Chu Feng's soul transmigrates into another world, where demons run rampant and the realm has fallen into chaos.

He inherits a medicine shop on the verge of closing, then suddenly obtains a tome of immortal medicine.

As long as he practices medicine to help the world and saves lives, he can earn rewards.
