A young man who was sold as a medicine slave was fused with an ancient soul fragment "Guixu" when he was about to die - it could swallow all the gains from cultivation, but every time he swallowed it, he would permanently lose a piece of his memory. He embarked on the road of revenge, but found that the ascension to the world of immortality itself was a trap that swallowed everything.
