The Villain Lied That I Was Invincible, and the System Took Him Seriously

I, Gu Changfeng, may be the most miserable transmigrator in history. The good news: I awakened a System that can make rumors come true. The bad news: it only listens to my nemesis. Scene One: At the sect tournament, my nemesis pointed at me. “He’s only pretending his cultivation has been crippled! He’s already cultivated back to the Sea-Congealing Realm!” Me, horrified: “I’m not! I haven’t! Stop making things up!” [System: High-emotion rumor received. Raising your cultivation to the Sea-Congealing Realm...] The elders in the crowd: “Tsk... How terrifying! He can suppress his cultivation to such an incredible degree!” Scene Two: After I “defeated” my nemesis, he cried out in frustration, “He must have inherited the founder’s legacy and gained the supreme demonic constitution!” Me, despairing: “Please, just shut up!” [System: High-intensity rumor received. Heaven-Demon Heart-Devouring Body (trial version) awarded...] The Grand Elder, emerging from seclusion: “This young man... is actually the hope of our sect’s revival!” Scene Three: Now my nemesis is locked in prison, roaring at the heavens, “Gu Changfeng is the reincarnation of an Immortal Venerable! He’s going to overthrow the entire Immortal Realm!” Watching tribulation clouds gather overhead, I’m completely numb. “Bro, I was wrong, bro! Come out and let’s talk this over for a few cents, okay?” Has he snapped?! Cultivation realms: Meridian Refining → Sea Condensation → Mansion Building → Nirvana Crossing → Transcendence → Saint → Emperor Lord → Immortal Venerable
