[Lottery + invincibility + leveling up + martial arts + ruthless, no saintly do-gooder]
Chen Shiyun transmigrates into an immortal martial world, becomes a barefoot doctor, and inherits a small clinic.
From the start, he masters the Huangdi Neijing completely, and selling medicine lets him draw prizes.
Manggu Zhuha, Five Poisons Demonic Scripture, Ice Silkworm Poison Palm, Life and Death Talisman, Yin-Yang Harmony Powder...
As Chen Shiyun grows stronger step by step, he suddenly realizes that things have taken a rather unexpected turn. I set out to heal the world, so why do the immortals all call me the Old Poison?
Listen, I can explain. I'm really a doctor.
