The thing i remember most is that the mc had a power to go back 1 day or smth each time he killed himself. There were superpowers in the world. The story starts with mc sitting in a room and watching TV of a powerful man. He eventually goes back to the time he wants and started re living. Then he sees the powerful man he saw on TV when he was not powerful and eventually kills him because that man evil. Then he meets a man who can see the kill count of ppl and he is hostile to mc because he sees a large kill amount on mc’s head and thinks he is a serial killer or smth. Mc says the numbers are due to killing himself and to prove he kills himself then and there
That novel is unreadable after the murim arc. It’s sad because it used to be one of my favorite novels.
