Supreme Medicine God System

Dumped by his girlfriend and out of work, Wang Youdao, already incredibly unlucky, is accidentally poked in the butt by a strange little girl and falls into a river. Upon waking, he discovers a Supreme Medicine God System has inexplicably appeared within his body. What? Taking pills and injections can level up? Damn, my body explodes if I don't complete a mission? Okay, you're so cruel! Strengthening techniques? Weakening techniques? Rejuvenation techniques? Haha, this is a complete skill training manual, right? This system is simply insane!
