The killing bureau started, and the old friend was killed. The wooden slip traced the clues all the way back, but happened to hit the fishing line. The known requirement: break the bureau. Killing to stop killing is the preferred way to break the situation. A health-preserving person enters the game with a sword. "Since you dare to use human life as bait, don't blame me for following the line and fishing in reverse." Along the way, all kinds of supernatural and fantasy events are intertwined into a network, and underneath the network, everything in the world is revealed.
