I Am a God in the Troubled Times of Demons and Ghosts

Demons and ghosts bring harm to the world and I am free. Who are the gods? I am a god! ... Chang'an relies on an old book with yellow paper to travel between two worlds In the troubled times of gods and ghosts, he is a small god with temples and statues worshiped by the people. In the modern city, he is a young heavenly master with transcendent Taoism and high spiritual power. While Chang'an accumulated incense and improved his godhood, he slowly grew from a lonely god in the wilderness to a Taoist priest in the dynasty, worshiped by the people of the world and the royal nobles. On the other hand, in the modern city where materialism prevails, holding a magic sword and using magic talismans, he becomes a distinguished guest that the rich are eager to invite. Some years later... When people from both worlds met, they suddenly discovered: The Taoist who calmed down the troubled times, eliminated the troubles of ghosts, and reestablished the order of gods and ghosts. The last modern heavenly master who exorcised ghosts and suppressed monsters. It's actually the same person!
