Everyone Else Is Afraid of Vicious Dogs, but They Don't Know That Dog Owners Are the Ones Who Have the Worst Nightmare

[Pure imagination, no system] Traveling through the world of immortality, I awakened a special physique and became stronger while sleeping. He doesn't do any work all day long and keeps a big black dog. Dogs roamed the mountain gate, biting talented people, chasing away elders, and hiding from everyone they saw. Rumors spread around the world: Once this dog comes out, not even a blade of grass will grow! Countless forces are sharpening their knives to get rid of this vicious dog. They are scared to death of dogs. As everyone knows—— The dog is just an arrogant shell, and I am the ultimate nightmare that destroys the world. The dog can get into trouble at will, and I will take care of everything for it!
