Chang Sheng Gou Said: Starting from Being an Undercover Agent in the Demon Sect

Lin Shi was reborn into the Immortal Sect's closed door, his spiritual energy was exhausted, and he had not left the Immortal Realm for nearly a thousand years. He had just learned that he was an undercover agent, but he never expected that he would be directly identified by the Demon Sect's spies the next second! When he was about to die, he relied on his survival system and experience as an undercover actor to kill the spy on the spot. Afterwards, Lin Shi was promoted from the Miscellaneous Court to the Inner Court, and received the survival reward "Divinity: Nine Heavens Divine Art" So far, he has been living in the Demon Sect as an undercover agent, cultivating gods to achieve immortality, hiding his true strength, killing people and demons to flatter a dragon, and thinking twice before making any decisions. I originally planned to just stay at the Demon Gate waiting for help, but I didn't expect that this was actually a huge scam! What's more, I didn't expect that I was not a "human"...
