Zheng Mingyuan is an ordinary online reader. His biggest hobby is writing long reviews for his favorite characters. Until one day, he received a strange message: "The character you saved, Peter Parker, is being eroded by an alien virus and is about to completely collapse." The next second, he traveled to the Marvel world. Here, Spider-Man has become an Internet celebrity who only posts to Moments all day long, Iron Man is obsessed with live streaming and selling goods, and Captain America has become a talk show actor - all the heroes' personalities have collapsed. What's even more frightening is that aliens are using this loophole to invade the earth, and only Zheng Mingyuan can correct his character through interaction. In order to save these ruined characters and return home, he started crazy operations: delivering food with Spider-Man who was carrying bricks, helping the blackened Iron Man to regain his original intention, and even preventing Captain America from attending the "Tucao Conference". But with each successful correction, a more powerful alien enemy is introduced. While saving the characters, Zheng Mingyuan discovered that there was a greater conspiracy hidden behind all this - aliens were rewriting the memory of all mankind, and he was the last hope.
