Gou Is Working as an Undercover Agent in the Sword Sect, Why Is the Whole Sect a Spy?

Lin Fan traveled through time and became cannon fodder at the bottom of the Demon Sect, and was sent as an undercover agent to the "Shushan Sword Sect", the largest sect of righteousness. He has his own "Heaven-defying Comprehension" system, and he originally wanted to secretly learn the peerless swordsmanship and then run away (in the early stage, he was extremely low-key and crazy to hide his clumsiness). But he gradually discovered that something was wrong: the usually sanctimonious master secretly communicated with the demon saint at night; the senior brother who spoke of benevolence, justice and morality was actually the reincarnation of a ghost cultivator. Except for the mountain guardian beasts, the entire sect is an undercover agent sent by various forces! In order not to be silenced, he was forced to be involved in a series of infernal affairs among undercover agents. Every time he acted on the spot, he could rely on his understanding to make the lie come true. In the end, he turned an empty sect into the largest sect in the world.
