Ghosts Revive, Others Control Ghosts and I Become a Buddha

During a trip, Chen Xuan, a migrant worker from Tianxuan, was buried by a plateau Buddhist temple that had been in disrepair and accidentally traveled to a strange world. I thought that as a time-traveler who was the Son of Destiny, he would rise up and become Long Aotian to conquer the world. I didn't expect that he would stay in a dilapidated ancient temple for twenty years. Just when he was about to lie down, the world suddenly went crazy. He actually met a group of strange people at the gate of his temple, and then the world began to change! System: Congratulations to the host, you have finally entered the drama mode and become a Buddha and become the ancestor of the system binding! The ghosts are about to resurrect, please prepare the host to harvest merit and become a Buddha immediately! Chen Xuan: What? When ghosts and monsters come back to life, how can I, an ordinary person, harvest merit? Chanting sutras? PS: No CP, system text, although the protagonist is a monk but not a pure virgin, sometimes a little selfish, some classic characters will appear in the text, but they are just in name, and the characters will be changed, please do not substitute too deep for the original characters. It's a semi-cool article, and you can dig holes. Please don't delve too deeply into the details and logic. My suggestion is to store and eat your brain, otherwise I'm afraid you'll scold me to death and no one will scold me.
