Ning Yuanzhou was bent on overcoming the poison of the mountain, and later solved it. He took the poison of his former dynasty for ten days and needed to take the antidote every ten days.
Ning Yuanzhou was poisoned by this poison because the Prime Minister of the State of Wu did not trust him to take the mission to the State of Wu and used this poison to contain him.
Ning Yuanzhou was injured once on the way, poisoned once and almost lost his life. It was Ren Ruyi who saved his life with the poison in her blood and Li Tongguang's panacea.
