Below the Great Emperor, I am at the Emperor Realm; Above the Great Emperor, I Cheat

“Lin Xuanqing is transported to the Sacred Purple Empyrean Sect and becomes an Ancestor, but has no cultivation power. To avoid exposing the fact that he’s a novice, he maintains a stern face and pretends to be a master for a full hundred years. Finally, one day, he awakens a system that can instantly kill Great Emperors: ‘Great Emperor Killer’: It can only kill Great Emperors specifically – this ability can’t defeat anyone except Great Emperors. So Lin Xuanqing decides to become a Great Emperor harvesting machine, cutting down all Great Emperors before him. This way, no one will dare question my identity as a powerful cultivator, right? All the Great Emperors cry out: Purple Empyrean Ancestor, please don’t come near us!”
