    Xiao Yan has a delicate appearance, with a lazy smile on his face. His lacquered black eyes sparkle with a brilliant luster, making him appear exceptionally gentle and profound. On its forehead, there is a flame mark, presenting many brilliant colors. Dressed in black, with a slender body and a free spirited demeanor, carrying a large black ruler diagonally on his back. On the surface of its body, brilliant flames are burning, and from a distance, it looks like a Flame God who controls the flames, full of inexplicable pressure.

    Light Novel

    The ruthlessness in his bones would chill people. If you didn't provoke these people, they were fine, once you did, they would be like a wounded hungry wolf in the desert who stare intently at you waiting for the moment when you become relaxed. In the past, Xiao Yan could leave behind the comfortable life in his clan because of the humiliation caused by Nalan Yanran cancelling the engagement. Clench his teeth tightly and battle Magic Beasts in the mountain range. Overcome the loneliness and isolation in the desert while going through tough training for three years. If he could be so cruel towards himself, just imagine how ruthless he is towards his enemies. At the bottom of Xiao Yan's heart, he had never thought of himself as a good person with a heart of gold. The least thing he could offer was to give some water to an injured stranger in the desert. If someone wished for him to protect and escort them out of the desert, he could only offer his apology. Xiao Yan may seem calm and composed, but inside, he deeply enjoys thrilling adventures, has an indomitable will, and even a devil-may-care attitude. Years of wandering have made Xiao Yan's personality as calm as a rock, even in the face of any challenge he is capable of adjusting himself to the most perfect state. Although he's usually gentle to others, there's a chilling ferocity hiding in his bones that will definitely kill anyone who provokes him. Later on in the light novel, this is demonstrated many times, as evidenced by people who were much stronger than him. When confronted with Xiao Yan, they quickly developed a very cautious and wary nature. If he sees an enemy as a significant obstacle in the future, he has demonstrated a tendency to go to extreme lengths to eliminate them. However, Xiao Yan was not a person who was totally cold-hearted. It was possible for him to be cold-hearted towards his enemies, however, to normal people or those who knew him, he was extremely kind. And this personality allowed him to have friends and experts gather around him. People like Hai Bodong, Little Fairy, Queen Medusa, and even Tian Huo Zun-Zhe all felt this. People who were cold-hearted towards their friends would struggle to get others to treat them genuinely. This point played a role in Xiao Yan's charm. Xiao Yan never reconnected with those who abandoned him in his years of hardship. He was aware that those who became respectful and friendly to him because of his resurrected talent would act like cold strangers when he lost his talent. This kind of backstabbing, experiencing it once was enough. A dragon's scales were impenetrable to touch. Those who did so would be subject to its wrath. It's clear that Xun Er, who had been thinking about him since they were young, was Xiao Yan's untouchable scale. As an alpha male, he had no intention of relying on a woman's name to strut around triumphantly.

    He wasn’t a person from this world. More accurately, his soul wasn’t from this world. He was from a deep blue star called Earth. As for unexplainable mystery of why he would be here, he himself had no clue. However, after living here for some time, he slowly realized: He passed through to the other side! In his past life, Xiao Yan was a mediocre, average commoner. Wealth, fame and beauty seemed to run parallel to his life, never intersecting it. Then, when he came to this continent, Xiao Yan was shocked. Because of a second set of experiences, his spirit became much stronger than the average person

    Xiao Yan is someone who reincarnated from Earth. In the Dou Qi Continent, Xiao Yan was born as the third son of the clan leader, Xiao Zhan.

    Xiao Yan is a genius who is considered by the people in his clan and town. At 4 he started practicing, and at 10 he achieved the 9th stage of Dou Zhi Qi. At 11, he broke the 10th-stage Dou Zhi Qi barrier and successfully condensed his Dou Zhi Qi Zu. He has become the youngest Dou Zhe in the clan for the past 100 years. Unfortunately, his label was soon stolen from him as all the Dou Zhi Qi he absorbed seemed to be completely gone. He dropped to Dou Zhi Qi, 3rd stage! From the position of a genius, he fell below the average person in one night. He had no clue what happened to his body and felt depressed.

    He was arranged to marry Nalan Yanran before he was born, as their grandfathers were very good friends. However, Nalan Yanran did not consider Xiao Yan worthy of her and rejected him outright, thereby creating a very strong motivation for Xiao Yan to become stronger, at least for 3 years.

    Volume 1: Wu Tan City

    After being considered as a genius and praised by the whole clan, Xiao Yan's cultivation falls to Dou Zhi Qi, 3rd stage. Xiao Yan is facing treatment that is completely opposite to what he received when he was a genius. His clan members took distance from him, mocked and insulted him, but the only light in this young man's life was a girl named Xiao Xun Er. He was always supported by her, despite her strong background and peerless talent. Troubles never come alone as Xiao Yan faces with his fiancée, Nalan Yanran and Ge Ye who comes to Xiao Clan and under the compulsion of the Misty Cloud Sect. She demands that Xiao Clan break the engagement between Xiao Yan and her. Xiao Yan is furious because his father is ashamed in front of the whole clan. He and Nalan Yanran have made a Three Year Agreement where they will face after three years in Misty Cloud Sect and decide their fates. Xiao Yan meets with Yao Lao and discovers that he is the real reason for his fall in cultivation, and of course he is happy because he finds out he can cultivate Dou Qi. He accepts a man in spiritual form named Yao Lao as his teacher. Yao Lao also decides to train him as an alchemist. With the help of many medicines and pills, Xiao Yan regains his cultivation even faster than before when he was considered a great talent. During the Coming of Age Ceremony, Xiao Yan showed his strength in front of the whole clan and announced that he is back. He regains his father's face, who was for years under the suppression of elders who saw him as a waste. There are happy people because of Xiao Yan's return. Those who once distance themselves from Xiao Yan, such as Xiao Mei, may never have the chance to have a good relationship with Xiao Yan again. Xiao Yan helps his clan by acting as a mysterious alchemist and comes in contact with Ya Fei of Primer Auction House. Xiao Yan was recognized by her, but she didn't reveal his secrets to anyone else. Taking into account the alchemist behind Xiao Yan, Primer Auction House has established great cooperation to assist Xiao Yan in dealing with the Jia Lie Clan. After all the clan arrangements are done, Xiao Yan leaves Wu Tan City to train hard for the upcoming challenge against Nalan Yanran.

    Volume 2: Magical Beast Mountain Range

    Xiao Yan was accepted into Jia Nan Academy, but he is asking for a one-year absence because of the Three-Year Agreement. Xiao Yan was granted a one-year absence after enduring twenty rounds against instructor Ruo Ling. His first training location was the Magic Beast Mountain Range, where he met the Little Fairy Doctor. He and Little Fairy Doctor discovered a cave where they found valuable items like a Flying Dou Technique “Eagle Wings” and a Rainbow Poison Book. But while they were in the cave, they were attacked by the Wolf Head Mercenary Company. Xiao Yan and the Little Fairy Doctor manage to escape. Xiao Yan goes deeper into the Magical Beast Mountain Range to practice his new Dou Technique, Flame Splitting Tsunami. While practicing, he witnessed a fight between two Dou Huangs ( Battle Emperor), Yun Yun and Amethyst Winged Lion. Xiao Yan was able to save Yun Yun after she was severely injured by Amethyst Winged Lion. Yun Yun was temporarily weak as her power was sealed. As she was attempting to pay back Xiao Yan, she tried to make some food, but at the end, she prepared it with an aphrodisiac. Xiao Yan's self-control saved them from ending up with sexual intercourse. Later, Xiao Yan helped Yun Yun, who introduced herself as Yun Zhi, to steal the Purple Spirit Crystal and by doing that Xiao Yan was able to obtain Amethyst Lion Birth Essence. After that, Yun Yun left Xiao Yan and gave him Sea's Core Vest, as well as the Dou Technique and Qi Method classes. After advancing his cultivation, Xiao Yan wiped out Wolf Head Mercenary Company. With the Little Fairy Doctor, he comes to the valley in the Magical Beast Mountain Range, which is rich in energy and rare medicinal herbs. Xiao Yan discovered that the Little Fairy Doctor has a Woeful poison body. After some time, they parted ways. Little Fairy Doctor left for the Chu Yun Empire while Xiao Yan continues his training in the Jia Ma Empire. Xiao Yan arrived at Black Rock City Alchemist Association where he received the badge for Tier 2 Alchemist and was pretty satisfied when he saw how much benefits every alchemist enjoys. He was the youngest 2nd Tier Alchemist in a hundred years. He made his way to Tager Desert, where he reunited with his two brothers, Xiao Ding and Xiao Li. They are happy to see that their young brother is no longer a waste. While visiting his brother, Xiao Yan happens to meet an intriguing girl named Qing Lin. He treats her as a human being, while others detest her existence as a hybrid between a snake and a human. Xiao Yan is assisted by Qing Lin in finding the Green Lotus Core Flame. Its location was found, but unfortunately Queen Medusa had already taken it.

    Volume 3: Green Core Lotus Flame

    Xiao Yan travels deep into the Tager Desert and even sneaks into Medusa's place, where the Snake-People were engaged in a fight against the group led by Gu He. Their goal was to obtain the Green Lotus Core Flame from Queen Medusa, but they were rejected as Queen Medusa used the Heavenly Flame to evolve. Xiao Yan was keeping an eye on her as she evolved. She was too lazy to deal with him because his cultivation was insignificant to her. After Queen Medusa evolved, she merged with the soul of the Seven-Colored Heaven Swallowing Python, which was taken by Xiao Yan. Xiao Yan obtained the Green Lotus Core Flame and quickly escaped with the Heavenly Flame in front of Gu He's group and the Snake-People Race. Gu He sent Yun Yun to get the Heavenly Flame, but she let him go after realizing that it was Xiao Yan. Xiao Yan went to Hai Bodong and obtained a map fragment for the Purifying Lotus Flame from him. Under the promise that he would refine a Tier 6 pill for Hai Bodong to recover his cultivation, Hai Bodong became his bodyguard. Xiao Yan headed back to Rock Desert City, the place where Xiao Yan's brothers resided. Xiao Yan helps their mercenary group, which escaped being destroyed by people sent by the Mo Clan. The Mo Clan abducted Qing Lin and sought to erase all evidence of those who knew Qing Lin and her Triple Jade-Green Snake Flower Pupils. Xiao Yan was enraged and went to Yan City where he killed the Great Elder of the Mo Clan. Unfortunately, he couldn't save Qing Lin because she was taken by the Sky Serpent Mansion. Xiao Yan used the Angry Buddha Lotus Flame to fight against Dou Huang Magical Beast Bai Ya, and he managed to injure him. But Yao Lao went into slumber due to high exhaustion of spiritual strength. Xiao Yan makes his way to Jia Ma Sacred City. Xiao Yan went to the Nalan clan under the name Yan Xiao to help Nalan Jie remove the 'Searing Poison' in exchange for the Seven Magical Green Spirit Saliva, which can recover spiritual strength. Xiao Yan is preparing to participate in the Alchemist Grand Meeting of the Jia Ma Empire.

    The Divorce, Meeting Yao Lao and The Return of a Genius

    Xiao Yan's fiancée, Nalan Yanran and Elder Ge Ye from the Yun Lan Sect arrived at the Xiao family household to announce the cancellation of the engagement between her and Xiao Yan that was decided by Nalan Yanran's grandfather when she was little due to Xiao Yan suddenly losing his talent and turning from genius to trash in an instant three years ago, much to the anger of Xiao Yan's father, Xiao Zhan. Xiao Yan, feeling his pride was wounded, stabbed his chest through Nalan Yanran's sword but was alive due to the sword not piercing his heart. Xiao Yan realized that he was not to die today and declared a divorce of Nalan Yanran. Nalan Yanran, frustrated, agreed to accept Xiao Yan's divorce if he could beat her on the Yun Lan Mountain three years after this day. She and Ge Ye then left, after which Xiao Yan collapses due to the lost blood from the stab wound. When Xiao Yan recovered and woke, he heard the servants guarding him mock him and wished him be dead. Xiao Yan exclaimed that he never expected a former genius would fall to the extent that even mere servants can mock him. Xiao Yan held out the ring left to him by his late mother, stating that it was the only thing it could truly call his own. Suddenly, a person began talking from inside the ring, surprising Xiao Yan. The person, or ghost, was Yao Lao and he asked Xiao Yan if he wanted more power. Xiao Yan dismissed this as a dream and went to visit his mother's grave and apologized due to being unable to fulfill the hopes she placed on him when he was young. He declared that he will not suffer the same humiliation a second time and Yao Lao appeared again at this. He told Xiao Yan that he was the reason that Xiao Yan lost his Dou Qi three years ago, as he was in the ring secretly absorbing his Dou Qi to gather enough energy to wake up from his "deep slumber". Xiao Yan threw the ring away in a fit of anger, and later cries out in regret because he threw the only thing his mother left him. However, the ring returned, and Yao Lao commended his temper. Xiao Yan then confronts Yao Lao, accusing him as the one who took away his talent and made him suffer all the humiliation over the years. Yao Lao told him that he can return his powers to him, and when Xiao Yan expressed disbelief, Yao Lao pulled out his essence flame, the Bone Chilling Flame, to prove his powers. Xiao Yan then told Yao Lao that he will forgive Yao Lao taking away his Dou Qi if he could help him break through to 7th stage Dou Practitioner, threatening to throw the ring away if he refused. Yao Lao offered to teach Xiao Yan the arts of an alchemist, which Xiao Yan, though initially did not believe, accepts and declared Yao Lao as his master. Yao Lao then told the impatient Xiao Yan to buy ingredients for an elixir. To gather the expensive materials, Xiao Yan took Xun 'Er on a shopping trip in the marketplace. Xun 'Er agreed to lend Xiao Yan a thousand coins, which Xiao Yan used to buy the ingredients, bargaining with the merchants in the process. Xun 'Er then ran away because she was angry at Xiao Yan abandoning her to find the materials in the marketplace, much to the puzzlement of Xiao Yan. Then, Jia Lie Ao arrived at the marketplace and attempted to hit on Xun 'Er by giving her a bracelet with a monster core on it. Realizing that the monster core was one of the items Xiao Yan needed, Xun 'Er let down her pride to take it, but was stopped by Xiao Yan who arrived and gave her a bracelet he bought, a bracelet Xun 'Er liked and wanted before, which Xun 'Er happily accepted. Jia Lie Ao, angry, proceeded to attack Xiao Yan, which was stopped by the head of security of the Xiao family territories. Jia Lie Ao then began to mock Xiao Yan about the mishap with Nalan Yanran, but Xiao Yan did not fight Jia Lie Ao over his provocations. Xiao Yan tricked Jia Lie Ao and his associates by stating a man Jia Lie Ao beat up before was a servant of the Xiao family, and Jia Lie Ao was forced to leave lest a declaration of war is made. Xiao Yan then found the core and a piece of metal with a Dou Qi skill inside, the latter mistaken for a regular piece of scrap metal. Knowing this, Xiao Yan bought the core and the scrap metal. Yao Lao revealed that the hidden Dou Qi skill was Vacuum Palm, a Xuan Class Low Lever skill, which Yao Lao dismissed as useless but Xiao Yan greatly revered. Yao Lao then used the materials Xiao Yan bought to create the Elixir of Foundation Spirits, an elixir capable of increasing his power quickly. Xiao Yan was then told by his father that the Coming-Of-Age Ceremony of the Xiao Clan is starting in six months instead of a year, a scheme by the other Xiao Clan elders to force Xiao Yan out of the clan, and Xiao Yan realized that the elixir his master made for him may not be enough to increase his strength to his original level in time. However, Xiao Yan declared he would not give up and will make the other clan members recognize his strength. On the way of returning from taking several skill scrolls, Xiao Yan witnessed a duel between Xun 'Er and his cousin, Xiao Ning, who was the child of the first elder of the Xiao Clan, which Xun 'Er wins easily. Seeing Xiao Yan, Xiao Ning began to mock him of losing his talent and hiding behind the powerful Xun'Er, and declaring that Xiao Yan was not worth Xun 'Er and that he will make Xiao Yan die of embarrassment at the Coming-Of-Age Ceremony, to which Xiao Yan replies that he looks forward to it. In the mountains, Xiao Yan begged Yao Lao to teach him a powerful skill, to which Yao Lao reluctantly obliges: the Xuan-Class Higher Level skill Octane Blast, which would become his signature move later on. Xiao Yan then undergoes hellish training with Yao Lao, in which the latter constantly blasts him with Dou Qi to train Xiao Yan's physical toughness to master the new move. When Yao Lao calls for rest, Xiao Yan refused, stating that he will make the ones who looked down on him repent. Yao Lao then continues the training throughout the night, stating that Nalan Yanran has awakened a monster by challenging Xiao Yan's pride with the cancellation of the engagement. Two months later, Xiao Yan had to buy new ingredients to make the Elixir of Foundation Spirits that was used up. Xiao Yan, too embarrassed to borrow money from Xun 'Er again, hatched a plan to auction lower-quality elixirs made by Yao Lao anonymously in exchange for the ingredients at the Miteer Auction House. There he met Mister Clooney, who was astonished that an alchemist of such skill was in town. The auction was held by the niece of Clooney, Ya Fei, that was curious about the anonymous alchemist. After the elixir and other items were auctioned off, Ya Fei brought in a Xuan-Class Higher Level skill Wind Swirl, which Yao Lao remarks as useless and told Xiao Yan that he would show him a true powerful skill when he had become stronger.

    •At 4 he started practicing, and at 10 he achieved the 9th stage Dou Zhi Li. At 11 he broke the 10th stage Dou Zhi Li barrier and condensed his Dou Zhi Qi Zu successfully. He became the youngest Dou Zhe in the clan since the past 100 years.

    •He was reborn into the Xiao Family.

    •On his finger was a black ring of simple design. The material used to make it was unknown. On it were some markings as well. This was the only present his late mother gave to him before she passed. He started wearing it since the age of 4 and even, 10 years later, he was still wearing. It was a precious gift from his mother and Xiao Yan treasured it dearly.

    •Though his Dou Zhi Qi was only 3rd stage, his spiritual awareness was akin to that of a 5 star Dou Zhe, perhaps even better.

    •He fed young Amethyst Winged Lion with laxatives.

    •Xiao Yan felt heartache by spilling Amethyst Essence so he licked it from the floor.

    •In the light novel, the first potion Xiao Yan made without the help of Yao Lao was an aphrodisiac. When Xiao Yan was being nurtured by Yun Yun she accidentally put this aphrodisiac in the fish she cooked. Xiao Yan and Yun Yun almost had sex because of Yun Yun's loss of control due to her Dou Qi being sealed. Xiao Yan loses his first kiss to Yun Yun during this time.

    •In the manhua it never really stated who Xiao Yan was in his past life however in the light novel it states "In his past life, Xiao Yan was a mediocre, average commoner. Wealth, fame and beauty seemed to run parallel to his life, never intersecting it." this suggests that in the past Xiao Yan was neither famous or rich as he was just an average person.

    •In the light novel its officially stated that he wore the ring that contained Yao Lao at the age of 4 and Yao Lao started absorbing Xiao Yan Dou Qi at the age of 12.

    •In the light novel he had a whole year to prepare for the coming of age ceremony while in the manhua he only had 6 months. However like the manhua he only needed 6 months to reach the 7th rank however reaching the 8th rank took a lot longer.

    •In the light novel, he didn't get robbed when he first entered the Black-Corner Region, in fact Yao Lao told him that this place is not a place where kindness and mercy exist, only those with enough ruthlessness and resolve can survive here, and Xiao Yan agreed wholeheartedly.

    •He started acting more flirty with Ya Fei after they became business partners and even defended her honor more than once. This left Nalan Yanran in shock as she thought he had a cold attitude towards her because of his personality.
