"What clue?"
Si Yao sighed. "Xiao Yu said there were no clues. The only clue is a self-portrait left behind by Liu Shou. He might have used the Three-Corpse-Slaying method to leave behind a portion of his divine soul, and just as his three thousand years of lifespan were running out, he entered the Endless Desolate Garden to search for the reaching-heaven pillar."
Saying this, she paused. "When he left to seek the Immortal Path, the demon calamity in the Western Transmission Realm had not yet risen. But ever since he left, the world has never seen him again, so everyone says he died in the Endless Desolate Garden. However, Qiu Wuya, the subsequent Alliance Leader of the Fuyuan Realm, obtained that painting through some unknown means and tracked it using the bloodline of Liu's descendants. Discovering that he was still alive, he suspected that he had advanced to become an immortal."
