BTTH: From Genius to Invincible

If Xiao Yan had never lost his Dou Qi initially.

If Yao Lao had died within the Soul Ring due to severe injuries.

If Xiao Yan happened to join the Hall of Souls by chance.

If a butterfly flapped its wings and altered the course of fate, how would the gears turn?

“.... Who are you?”

“Hall of Souls, Xiao Yan!”
