Let All the Knives Disappear into Smoke

The boy accidentally obtained the "Knife-killing" system. There are always some things that are difficult to reconcile in every world. He travels through all the worlds, changing the stories within them. In the world of "Fox Fairy Matchmaker", is the mask organization going to go outside the territory? He works as a security guard! Is it difficult to reconcile the love between soldiers, kings, wealth and wealth? He works to promote the multi-child policy. In "The Shape of Sound", he reduces the dimensionality and strikes. In "Original God", what happened with the emperor in the end? He did ideological work for the emperor, is it about to end in the end? He lives for a thousand years until his death. Did Raiden really die in the Demon War? He became the ambassador of world nuclear peace... There will always be some setbacks in life. What if you have to suffer while watching animations and playing games? Then the whole life will become boring and boring!
