Afterward, Fang Lin followed the young boy and witnessed his rise to power step by step, as he immersed himself in the Tao of alchemy in the face of despair, eventually becoming a master of Pill. Also, he successfully controlled the Poisonous Human Bloodline with the power of pills, which prevented any further outbreaks in his later years.
Eventually, the boy didn't leave any offspring. He quietly passed away, having lived for only two centuries, while many Pill Refiners admired him.
The Poisonous Human Bloodline, after all, was too rampant and against nature. Even though the boy perfectly controlled it, it reduced his lifespan.
With the achievements of the boy, he could have lived for four or five hundred years. However, he only lived for two hundred years because the Poisonous Human Bloodline remained, not being completely removed.
However, the boy neither married nor left any offspring, so the Poisonous Human Bloodline was considered extinct.
