Background

Xiao Yun transmigrated into the Battle Through the Heavens world as Xiao Zhan's fourth son and Xiao Yan's younger brother. He began with only Second-Stage Fighter's Qi and was immediately framed by Xiao Ning for stealing a Yellow-tier fighting technique. Xun'er provided an alibi, preventing the elders from punishing him. 1

Following the incident, Xiao Yun awakened the Attribute Copy System. Its first successful copy gave him Xiao Zhan's Five-Star Da Dou Shi strength, overturning his reputation as a useless clan junior. 1

Personality

Xiao Yun is calculating and secrecy-conscious. He conceals both the system and his actual cultivation, attributing his sudden gains to a vague “fortuitous opportunity.” He also acquired alchemical ingredients gradually from several shops and refined pills in a secluded back-mountain cave to avoid attention. 3 7

He remains composed when challenged by stronger-looking opponents, answering Xiao Ning, the First Elder, Jia Lie Ao, and Nalan Yanran with mockery rather than visible fear. 6 7 12 19

His protection of allies is paired with extreme ruthlessness toward enemies. He defended Xiao Yi Xian from the Wolf Head Mercenary Group, killed several attacking mercenaries, and later killed Mu She and Mu Li after they begged for mercy. 23 25 27

Xiao Yun's thoughts toward Xiao Yi Xian are possessive: after recognizing her in Qingshan Town, he decided to make her one of his future romantic partners. 22

Story Role / Major Arcs

Rise within the Xiao Clan

After escaping Xiao Ning's false accusation, Xiao Yun awakened the Attribute Copy System and rapidly became one of Wu Tan City's strongest figures. He publicly defeated Xiao Ning, repelled the First Elder, and overturned the clan's view of him as worthless. 1 6 7 10

He also used his alchemy to strengthen Xun'er, earning her trust and drawing Xiao Zhan's attention to his hidden capabilities. 3 4 5

Conflict with the Jia Lie Clan

At the Xiao Clan market, Xiao Yun defeated Jia Lie Ao after the latter insulted both him and Xun'er. His strength later became associated with the death of Jia Lie Bi, causing Xiao Clan disciples to fear that Yun Yun's visit might bring retaliation. 12 28 29

Engagement Repudiation Incident

When Nalan Yanran arrived to dissolve her engagement with Xiao Yan, Xiao Yun defended the Xiao Clan's dignity. He broke her sword, intimidated Ge Ye, and exposed himself as a Dou Wang before gaining a system reward that elevated him to Dou Emperor. 18 19 20

When Yun Yun later visited, Xiao Yun accepted Nalan Yanran's challenge and publicly released his Dou Emperor aura. The incident forced Yun Yun to discipline Nalan Yanran and led the Misty Cloud Sect to regard Xiao Yun as a figure better befriended than opposed. 29 30 31 32

Qingshan Town and Xiao Yi Xian

A system mission brought Xiao Yun to Qingshan Town, where he rescued Xiao Yi Xian from the Wolf Head Mercenary Group. He defeated Mu Li, exposed his Dou Emperor cultivation to Mu She, and eradicated the father-and-son leadership after their attempted retaliation. 22 23 25 26 27

After obtaining a formula for the Woeful Poison Body, Xiao Yun persuaded Xiao Yi Xian to remain with him for three months so he could resolve her constitution's danger. He later brought her to the Xiao Clan and supplied her with a cultivation pill. 27 28

Mittel Auction House Cooperation

Ya Fei began pursuing a working relationship with Xiao Yun after recognizing both his alchemical ability and his status as a teenage Dou Emperor. Xiao Yun accepted her invitation to the Mittel Auction House while considering additional materials, equipment, and Dou Techniques he could acquire there. 10 34
