Dual male leads, infinite-loop trials + fake replacement trope + salvation + two equally powerful leads, the foremost champion of the righteous path vs. the supreme ruler of the demonic path.
Yue Yunluo, lord of Buzhan City and supreme ruler of the demonic path, possesses an extremely yin constitution. With his cultivation stalled, he orders his subordinates to capture someone with an extremely yang constitution to help him break through in his demonic cultivation.
But those blind fools went and kidnapped the foremost champion of the righteous path, who was investigating a missing persons case.
Fine, they’ve already caught him. A rare, pure-yang body like that shouldn’t go to waste, so he might as well refine him into a cultivation vessel.
Who could have guessed that the righteous champion would suddenly recover his martial arts and fight him? They both fell off a cliff.
When he opened his eyes, he found himself trapped in an endlessly repeating illusion, with his mortal enemy right across from him. Even worse, that enemy lost his memory at the start every single time!
So he was forced into one role-playing scenario after another, struggling through endless loops, until one day a mysterious figure told him that the only way to break the illusion was to cultivate together with the pure-yang body...
