A good-for-nothing boy was reborn as a sophomore in high school after a car accident. He was bound to the system of "you can become stronger by lying". The world's credit debt became a countdown hanging above his head. If he didn't pay it off, there was a risk of being wiped out at any time. He was forced to become an "active liar". Struggling at the bottom of the wasteland world, should he change his destiny against the will of heaven, or fall into reincarnation again?
