Start with Immortality

[Funny, no heroine, no knife, the protagonist likes to watch the fun and is brave] Li Changxiao accidentally traveled to a world called the Ancient Beast Realm, but fortunately he had a cheat system. But on the first day, the system tricked him into giving him a Gouyu immortality technique, and at the same time forced him to sign a contract with a dog. "Chang Xiao, why don't you smile? Chang Xiao!" During the sparring session, he "accidentally" showed off his eighteen diamond-encrusted gold-rimmed abs, which shocked his opponent! I, Li Changxiao, have no interest in fighting and killing, so I'll leave it to you if you want! What! You said you wanted my dog! Then go die!
