Background / History

Xiao Yu was originally a resident of Blue Star who transmigrated into the Dou Qi Continent and became Xiao Yan's younger brother. He spent fourteen years in the Xiao Family before awakening his system, having initially relied on his knowledge of the future and stayed close to Xiao Yan and Xiao Xun'er for protection. His first sign-in reward was the Bone Spirit Cold Flame, which immediately accelerated his cultivation. 1 2

He cultivated alongside Xiao Yan and Xun'er, gained the Pill Codex's alchemical knowledge, and began refining medicines such as Snow Jade Spirit Liquid. His exceptional talent led the Xiao Family to open its Dou Qi Pavilion to him ahead of schedule. 9 16

During his travels through the Magic Beast Mountain Range, Tagor Desert, and Jia Ma Empire, Xiao Yu obtained flight capability, encountered Yun Yun, aided Xiao Yi Xian with the Calamity Poison Body, and became involved in the conflict surrounding Qing Lin and the Heavenly Snake Mansion. 28 41 87 98

After confronting the Misty Cloud Sect and Soul Hall operatives, he openly claimed responsibility for Yun Yun and their daughter Xiao Nian. His increasing strength and knowledge of Soul Hall's activities prompted him to establish the Underworld, intended both to protect the Xiao Family and oppose Soul Hall. 150 160 198 346

The Underworld expanded from the Black Corner Region into the Central Plains, gaining Jia Nan Academy's support, absorbing allied families and experts, and establishing its headquarters in the Wind Thunder Mountain Range. 282 492 508

Following his rise to the Dou Emperor realm, Xiao Yu entered the Great Thousand World. There he founded Chaos Palace on Tian Luo Continent, sought to unify the continent's fragmented powers, and became a major threat to the Phoenix Clan, the Futuo Ancient Clan, and the Outer Domain Evil Clan. 697 711 727 750

Appearance

Xiao Yu is introduced as a handsome young man with sword-like brows and starry eyes. During major breakthroughs, his appearance can visibly change under the influence of his cultivation. 1 559 682

• Black eagle-wing tattoos can appear on his back and manifest as tangible flight wings. 28
• The Prison Suppressing Divine Body produces faint black-gold runes across his body when activated. 559
• After comprehending Source Qi, his eyes turn amber and gain an unusually profound appearance. 682

Personality

Xiao Yu is pragmatic and calculating. Before his system awakened, he deliberately remained close to Xiao Yan and Xun'er because he understood their future importance and wanted reliable protection. 1 389

He is protective of those he considers family or companions. He risks himself for Qing Lin, seeks methods to help Xiao Yi Xian control her constitution, supports Xiao Yan, and repeatedly uses his influence to secure the Xiao Family's future. 9 41 87 231

Although he often teases Xun'er, Xiao Yi Xian, Cai Lin, and Zi Yan, he becomes ruthless toward Soul Hall and anyone threatening his loved ones. He can also show restraint, such as sparing the Heavenly Snake Mansion due to Qing Lin's ties to it and disabling Lin Guannan rather than killing him before Yao Ye and Yao Yue. 106 302 430 650
