Gu Fan was forced to sign a contract with the devil and help the devil develop games to harvest negative emotions. As a scapegoat and tool man, he could only make junk games strictly according to the design plan provided by the devil. Not only could he not make any money, he would also be cast aside by countless players.
So, Gu Fan decided to save himself as a programmer: he wanted to hide a BUG in the code of these junk games, change the core gameplay of the games, and make these junk games become classics!
