Several readers have reported that they can't figure out why the protagonist obviously has a Grim Reaper system, but Wu Yuan, the master, and left because of a simple marriage, and the bear child will explain to you again: First of all, the people faced by the Grim Reaper system in this novel are more than ordinary people, and the Grim Reaper system cannot forever allow the protagonist to be strengthened without hindrance, in that case, there is basically no one in the entire world who cannot be killed, and it is pure Shuangwen in this way, and it doesn't mean much. Secondly, the real reason is not marriage, but the reason is the enhancement limit mentioned later, and the protagonist originally wanted to collect souls to convert death points by being a killer, (could there be any other class that is easier to kill than a killer?) So these two points are the reasons why there is a master, and the marriage is just a fuse, a reason for the protagonist to leave temporarily.
