I Let You, the Demon Sect, Be an Undercover Agent, and You Become the Demon Lord for Me.

Lin Yuan, a handyman disciple of Yunxiao Immortal Sect, number 973. His daily job is to chop firewood, carry water, and clean toilets. He eats pig food and sleeps on a bunk bed. He is not even qualified to practice. He is so miserable that he is embarrassed to say that he is a time traveler. Until one day, the sect's "smart eye" picked out twelve of the most ordinary and inconspicuous hapless guys from the three hundred handymen and sent them to the Demon Sect as undercover agents. Lin Yuan is one of them. Before leaving, the elder of the Immortal Sect said earnestly and thoughtfully: "I will have a narrow escape from death, but for the sake of the sect's justice, you must endure the humiliation, spy on information, and wait for the sect's call!" Lin Yuan's MMP in his heart: If you can do it, go ahead. Fortunately, he also has a "Thousand Worlds Complaint System" that comes with time travel - although this system can only make sarcastic remarks and give bad ideas, it can at least give him a warning before he dies. In the demon gate, murderous intent is taking place at every step. Temptations by elders, plots by fellow sects, treasure hunts in secret realms, hearts eaten by demons... Lin Yuan relied on the pitiful prompts from the system to escape death time and time again. I don't know what happened as a result—— The elders of the Demon Sect thought that he was born with a demonic body and rushed to accept him as his successor. The Holy Maiden of the Demon Sect felt that he was the destined one and insisted on cultivating with him. Lin Yuan:? ? ? I just want to go back and do business alive! Many years later, Lin Yuan was sitting on the top of the Ten Thousand Demons, with hundreds of thousands of demons bowing their heads behind him, and beside him was the Demon Sect Saint's red sleeves. "Go back and tell the leader that the undercover mission has been completed. From today on, the Demon Sect will be merged into the Immortal Sect - the Immortal Sect with me as the leader."
