Imprisoned under the Guixu tree for three thousand years, Xie Wudu guards a wrongful case he shouldered for someone else three thousand years ago. The young woman A Zhao arrives with her sister's lingering soul; with a sixty-day limit, she brings him an enticement every day, asking only to borrow his flesh to reshape A Fei's soul. He knew well that every bite of the enticement engraved a soul-locking contract upon his spirit. He knew that on the sixtieth day of sacrifice, he would be eternally buried at the root of the tree. The tender companionship was all a farewell; the sweet daily life was all a scam. Behind the scenes, Heng Yuan lays out a full chess game, using the obsession of the two to escape the destiny of guarding the tree. When the truth is torn open, the desperate predicament of choosing between two is laid before his eyes. How should he choose?
