I've Guarded the Demon-Suppressing Pagoda for Ten Thousand Years, and You Still Treat Me Like a Tool?

The Demon-Suppressing Sect sealed away peerless hordes of demons for eighty thousand years, until the world gradually forgot it existed. Qin Heng took over as the sect’s new leader and exhausted himself trying to keep the grand formation running. After finally producing some ox-demon dung to cover expenses, he found that its miraculous healing effects had attracted the covetous attention of rival sects and factions. They surrounded him, threatened him, and demanded answers. After enduring endless torment inside the Soul-Refining Banner, his mind finally broke, and he was reborn on the day his sect was destroyed. Fine! Fine! The sect guarded the world in silence for eighty thousand years, and this is how it gets repaid? Then I’m done serving humanity. Why not join these peerless demons and take humanity’s side as my enemy? That sounds far more satisfying. Black Fiend Star Ox Demon Venerable: “Boss, these people can’t take a hit.” Thunderflame Holy Tiger Demon Venerable: “My king, I think this city-protecting formation is more fragile than an eggshell.” When the people of the sacred lands and imperial dynasties are devastated and beg the Demon-Suppressing Sect to step in and seal these monsters away once more, Qin Heng says, “I had no choice before. Now I choose to be the villain.”
