Everyone knows that the immortal master Cui Jibai and the demon king Kuai Zai have been mortal enemies for half their lives.
Little did the world know that when Cui Jibai died, Kuai Zai was the only one willing to die with him.
Not to mention that the world didn't know it, even Cui Jibai himself couldn't figure it out, how could he be reborn with Kuai Zai? Are they bound together by the system with a void red thread?
Kuai Zai: Damn it! Who wants to be tied to this annoying guy? My wise life will be ruined in one day!
Cui Jibai: Just talk, why do you have to hold hands and talk?
Kuai Zai: Do you think I am willing? It's not a damn system. Otherwise, who would be tied to you? This king's wise life will be ruined in one day!
Cui Jibai: You should let go first.
Kuai Zai: ... Don't let go.
When two enemies, one good and one evil, were born, the two people who the whole world thought were mortal enemies got together.
