Transmigrant Medicine Man (T3M)

After living abroad for most of his life, Zhang Chengyu struggles to adapt to life in China. After failing his high school entrance exam test, he flees the city for the countryside, where he falls into a well that transports him to the past. Only, it doesn't seem to be the one he learned about in history class; instead, it's a parallel world where magic is real, and he must learn to wield it in order to return home. Until then, he must become a medicine man and learn to play his cards right in order to fall in with the right people.
