After quitting his job unexpectedly, Su Li spent ages wandering around without finding work. One day, while strolling by the road, he suddenly saw a little girl, around seven or eight years old, step into the street. In the blink of an eye, Su Li rushed forward and shoved her out of the way, only to be struck and thrown by a truck himself. Su Li insisted on deleting his entire phone browsing history and secret photo album before passing out. Just when he thought he had died, his consciousness suddenly appeared in a mysterious space, which gave him a second chance at life. He became a spy for the Knowledge Paradise, an agent tasked with transmigrating between worlds to steal secrets.
