Undercover Demon Sect? I Quit!

Chen Yuansheng, who has traveled to the world of immortality for more than 170 years, finally realized the ultimate secret of long-term survival in the world of immortality, which is to "cosmetic". Don't attract the attention of your fellow sects, don't attract the attention of your enemies, and you can live forever if you just do so. However, the Qingyang Sect wanted to send a disciple with no power, no background, and no one noticed to go undercover at the Ten Thousand Demons Sect. Chen Yuansheng couldn't be more suitable and was forced to accept the undercover mission. After living in obscurity for hundreds of years, no one heard about it, but once he was undercover, the whole world knew about it! In this way, Chen Yuansheng embarked on a broad road to becoming a "gou" saint.
