Background / History

Xiao Yu was originally from Blue Star and transmigrated into the Xiao Family. Before gaining a system, he deliberately stayed close to Xiao Xun'er because he knew her Gu Clan background and recognized the protection that connection could offer. He cultivated during the day and secretly used Dou Qi to nourish her body at night, becoming the person closest to her within the Xiao Family. 1 389

His first sign-in reward was the Bone Spirit Cold Flame. Its absorption elevated him from one-star to four-star Dou Zhe, establishing the Heavenly Flames as the foundation of his subsequent cultivation. 1 2

At the Xiao Family's confrontation with the Misty Cloud Sect, Xiao Yu defeated Ge Ye's four-star Dou Zhe disciple Xia Jie in one punch. Nalan Yanran subsequently challenged him to meet again at the Misty Cloud Sect in three years. 6

During his travels, Xiao Yu used the identity “Xiao Shi Yi,” encountered Yun Yun in the Monster Beast Mountain Range, and later refined the Green Lotus Core Flame into his second Heavenly Flame. 29 77 He eventually revealed his true identity at the Misty Cloud Sect's Three-Year Agreement gathering, where he was also recognized as the Alchemist Grand Meet champion. 147

Xiao Yu became involved in the conflict surrounding the Misty Cloud Sect, Yun Shan, and the Soul Hall. He exposed Yun Shan's Soul Hall ties, protected Yun Yun and their daughter Xiao Nian, and killed Soul Hall operative Wu Ying. 151 158 160

After learning of the Soul Hall's threat and the Xiao Clan's fallen history, Xiao Yu resolved to form the Underworld. Its stated purposes were protecting his family, consolidating power in the Black Corner Region, and opposing the Soul Hall. 198 293 346 Under Ya Fei's administration, the Underworld later occupied the Wind Thunder Mountain Range and made it its Central Plains headquarters. 508

He developed into a renowned alchemist as well as a cultivator. His refinement of a Grade 8 pill with Nine-Colored Pill Lightning earned him recognition as a peak eighth-grade alchemist and restored the Pill Tower's prestige against the Soul Hall. 540

After entering the Great Thousand World, Xiao Yu established Chaos Palace in Tian Luo Continent and became a leading force against the Outer Domain Evil Clan. 724 730 748

Appearance

Xiao Yu retains youthful features even when recognized as a powerful expert. He has displayed black eagle-wing tattoos that transform into tangible wings, as well as black-gold runes across his body after cultivating his physique. 28 100 559

• Black eagle-wing tattoos on his back, capable of manifesting as wings. 28
• Dark-golden Dou Qi wings upon reaching Dou Wang. 227
• Black-gold runes on his cultivated physical body. 559
• Chaos Fire can form dark-golden armor around him. 625

Personality

Xiao Yu is highly calculating and plans far ahead, particularly where his family and the Underworld are concerned. He chooses relocation, alliances, recruitment, and displays of strength according to their long-term value rather than immediate comfort. 101 198 293 576

He is deeply protective of those he considers his own. This extends from supporting Xiao Yan at the Three-Year Agreement to protecting Xiao Nian, aiding Xiao Yi Xian's cultivation, and confronting powerful factions on behalf of Ya Fei and Yun Yun. 113 151 294 475

In battle, Xiao Yu is ruthless toward hostile forces, particularly Soul Hall operatives and factions that threaten his companions. He is also notably confident in his own strength, often choosing intimidation or direct confrontation over negotiation. 118 491 496
