I Rely on Medicine to Start the Apocalypse

Yinli, the number one pharmacist in Yunluo Continent, traveled through the apocalypse and became a useless person! Is it just you who has the final say? When my potion comes out, it won't be directed at anyone, everyone sitting here is rubbish! Torturing rookies, beating the corpse king, protecting the world, and saving people. The whole apocalypse is boiling, and all the big guys are offering their love! Finally, the arrogant little cat in Yinli's arms couldn't sit still anymore and became the number one person with doomsday powers! "Have you forgotten me?"
