The Two Gatekeepers Are All Demon Emperors! You Said He Is a Mountain Village Doctor?

Li Changsheng traveled to a foreign land, and in this world full of immortal cultivators, he became a mortal with no spiritual roots. An unreliable system and a dilapidated medical clinic. Everyday salted fish lies down leisurely. Little did he know that the fish he raised were ancient golden dragons and the chickens he raised were of the prehistoric phoenix species. A bowl of fresh soup can make people soar from the ground, and they can doodle at will, but it is like a supreme fairy weapon Although he is a mortal, he can attract countless powerful people to visit him, and he is like a dog and horse. What, it turns out that I am already invincible.
