Super Killing Adventure

This is a killing game, between killing and being killed, you have no choice! In the Slayer Alliance, everyone comes from different planets. If they fail to complete the designated tasks, they and the planet they belong to will be destroyed... Is it survival? Or death? The only thing you can do is to keep getting stronger! Ding Lei unfortunately signed a devil's contract. As an agent of the earth, he will embark on a series of challenges full of killings. Fortunately, he actually obtained the dark super power... A mysterious power that can swallow everything! PS: The completed work "The Peerless Physiologist" has 2.2 Million words. Friends who are interested can read it.
