It Turns Out I Am the God of Medicine

"Senior Medicine God, can you sell me a bottle of amoxicillin? I am willing to exchange the artifact!" "Master Medicine God, do you still have high-calcium tablets?" "Master God of Medicine, can you sell me another bottle of Soothing and Brain-Replenishing Liquid? I am willing to be your slave." … Li Cheng wanted to say, I am just a mortal selling medicine, not a medicine god. I am under a lot of pressure when you big guys are so shameless and flattering! Until many years later, Ye Cheng was confused. Some people drank energy drinks and fought across realms. Some people used honeysuckle dew to extinguish the divine fire. Those who took calcium tablets every day became physically holy. Those who often bought calming brain supplements became spiritually powerful... Even the watchdog realized the supreme power after eating children's cough syrup.
