When Chen Feng traveled to the world of martial arts, he took with him a system that went to the wrong set. What was even more unfortunate was that the once-in-a-lifetime opportunity to make a wish actually fell on a middle school boy with a strong sense of justice. Even if he is ready to play support for the rest of his life, sometimes, the speed at which this guy does things is really unbearable. In addition, there is a cat system that has completely degenerated into a mess and is waiting to die, a landlady who is gentle on the surface but is actually a cat burglar, and a group of forces who are inexplicably preparing to kill him... Chen Feng feels that the most difficult job in the world is definitely the best support in the world.
