Bi Su

Bi Su is Black Mountain Tribe's favored young prodigy and the principal junior opponent of Su Ming during Dark Mountain's destruction. Ambitious, cruel, and protected by Bi Tu's resources, he performs near Feng Zhen's strongest youths before dying to Su Ming's final arrow while pursuing the refugees.

Biography

Dark Mountain and the Berserker awakening

Bi Su arrives at the Wind Stream trial as an unknown outsider, quickly competes for second and third place, and declares that he will surpass even Ye Wang. His prepared endurance and seventh-level Blood Condensation cultivation justify much of that confidence, but he dismisses the slowly rising Mo Su until the disguised Su Ming overtakes the leaders. Back with Black Mountain, Bi Su reveals a crueler ambition: he kills a small animal to extract green qi, joins the assault on Dark Mountain, and recognizes Su Ming as Mo Su during the battle. (Chapters 52–92)

Bi Tu has given Bi Su a blood-mist defense shaped like Wings of the Moon and said it can stop attacks below Awakening. Su Ming's blood-covered, moonlit arrow breaks that protection, pierces Bi Su, and kills him before he can reach Lei Chen. His death terrifies Black Mountain's fighters because Bi Tu had invested everything in him. Someone later removes his corpse, but the original Bi Su does not return. (Chapters 93–102)

South Morning and the Immortal conflict

Much later, Su Ming learns of Bi'su, a female Sacred Lady of Evil Lust Sect, and sees a male Immortal counterpart who has Bi Su's face. The narrative and translation notes distinguish these people from the dead Black Mountain youth. Their presence reflects the paired identities surrounding Yin Death and the Immortal lands, not Bi Su's resurrection or later cultivation. (Chapters 642–650)

Appearance and personality

Bi Su is a black-clad youth under twenty whose hair or clothing obscures half his face. His eyes burn with fanatic ambition, and his expressions become gloomy, cruel, and fearful as circumstances change. He is competitive and prepared, but his confidence rests heavily on status and Bi Tu's protection; facing death exposes panic rather than resolve. (Chapters 53–57, 90–95)

Abilities and cultivation

Bi Su reaches the seventh level of Blood Condensation and shows endurance on Wind Stream's pressure path. He can draw green qi from a freshly killed animal into his brow, though the dossier does not establish the lasting effect. (Chapters 53–77, 90)

His Wings of the Moon blood mist is a protection supplied or taught by Bi Tu and is said to stop sub-Awakening attacks. It fails against Su Ming's arrow because the blood and moon power cause the mist to recoil and melt, showing that the defense has affinities and counters rather than absolute realm-based immunity. (Chapter 95)
