I Am in the Demon Sect, I Use the Immortal Cauldron to Cast Immortality

[No system] [Multiple heroines] [Ambiguous] [Not the Holy Mother] Yang Lin traveled through the world of cultivation. He became a disciple of the outer sect of the Biyang Demon Sect who was in charge of the pharmacy. Being in the Demon Sect, everything is precarious. As soon as the game started, the sisters forcibly took supplements. He was also blackmailed and threatened by the manager of the pharmacy.

"Junior brother, let's do it again!"
