With this coffin, Leng Xuan successfully escaped the deadline and waited for an era suitable for cultivation. It's just that after he came out of the coffin, he found that both the strong ones in the mouth of humans and the supreme beings of demons seemed a bit weak. ... Earth-level demon: "Hey, hey, he was just passing by, and his leg was broken." Heaven-level demon: "Humans are just blood food for us! Damn it, what the hell is this?" Strong man outside the world: "I just wanted to capture a few slaves, but I ended up becoming a slave myself." Many years later, Leng Xuan couldn't help but shake his head when he looked at the powerful men at his feet. "Why is there no one who can fight?" This novel and its characters are purely fictitious.
