[Mortal flow + no system] Zhang Yang was originally an employee of a modern traditional Chinese medicine pharmacy. He had worked diligently for more than 20 years, but unexpectedly he was reborn in the miraculous medicine dynasty. My original intention is to live well in this world by relying on my old skills.

The germination of an unknown seed made him the enemy of the world. … See how he survives in this world and finally transcends.
