Background

Xiao Yu transmigrated from Earth into the Xiao Clan as Xiao Yan’s brother. Before gaining any special power, he intended to rely on Xiao Yan’s future potential and on Xiao Xun Er’s Ancient Clan background, using his knowledge of the original story to secure protection and opportunities. He remained close to Xun Er from her childhood and cultivated alongside her. 1

During the Xiao Clan Family Trial, Xiao Yu’s sign-in system finally awakened. Its first reward was the Bone Spirit Cold Flame, the Heavenly Flame originally associated with Yao Lao. This transformed his prospects and began his rapid rise through the Dou Qi Continent. 1 2

He joined Jia Nan Academy alongside Xiao Yan and Xun Er, but delayed his enrollment to pursue his own affairs. During this period, he protected Xiao Yi Xian, secured Hai Bodong as a year-long guard, confronted the Mo Family, and ensured Qing Lin could train safely with Heavenly Snake Mansion. 23 38 91 100

After returning to Jia Nan Academy, Xiao Yu became a central figure in Pan Men. His strength destroyed the Bai Gang’s standing in the Inner Academy, earning him the name “Overlord Xiao.” He later established the Underworld in the Black Corner Region, eliminated hostile factions, and began relocating the Xiao Clan and Mite'er Family there. 228 235 293 308

His conflict with the Misty Cloud Sect exposed Yun Shan’s ties to the Soul Hall. Xiao Yu fought Wu Ying, protected Yun Yun and their daughter Xiao Nian, and made opposing the Soul Hall one of the Underworld’s defining purposes. 151 158 160 346

After attaining Dou Di, Xiao Yu entered the Great Thousand World with Xiao Yan and their companions. He founded Chaos Palace, became involved with the Great Luo Heavenly Domain, trained disciples such as Nine Nether, and built a reputation strong enough to deter major Beast Realm and Great Thousand World factions. 682 697 699 727

Appearance

Xiao Yu is described as a young, handsome man. His appearance changes markedly when he channels his cultivation, physique techniques, or transformed Dou Qi. 288 437

• Black eagle-wing tattoos appeared on his back after obtaining his flying Dou Technique; they manifest as wings over three meters long. 28
• His Dou Wang wings are dark gold and are regarded as noble in appearance. 227 294
• Breaking through to Dou Wang exposes a notably muscular physique. 222
• Black-gold runes emerge over his body when his physique cultivation is active. 559
• After comprehending Origin Qi, his eyes become amber and unusually profound. 682

Personality

Xiao Yu is ambitious, self-assured, and strongly focused on personal strength. His early dependence on powerful future allies does not prevent him from cultivating tirelessly; once his system awakens, he pursues enough power to protect himself and those around him. 1 218

He is protective toward people he considers his own, including Xiao Yi Xian, Qing Lin, Ya Fei, Xiao Nian, and the Xiao Clan. This protection is often expressed through overwhelming force and explicit threats against anyone who harms them. 38 98 100 294

Xiao Yu can be ruthless toward enemies. He kills Gan Mu without leaving evidence, severely injures Luo Bu after defeating him in one move, and tortures Wu Ying before killing him. 22 38 158 Despite this, he can be playful with friends and family, particularly Hai Bodong, Zi Yan, Xiao Yan, and his daughter. 91 231 240 651
