As the oath had said, there was nothing in the world that the Silver Hand could not cut off.
Of course, it was just a cut, not a kill. The ocean was huge. Even if Lu Chen's Silver hand could cut the surface of the ocean open and stop it from closing up, it still wouldn't be able to kill the ocean of life.
However, the death god was different. He had a physical form with the God of War. Although such an existence was more powerful in attack, the existence of his physical form also made it possible for them to be killed.
"What are you going to do?"
Lu Chen was waiting for the Grim Reaper to escape. But one had to admit that even if a person had gone crazy, the pride of a God was still there. In the face of a 'mortal's' provocation, the God of War didn't choose to avoid it, nor did the Grim Reaper.
