Ren Jie found a mysterious supercomputer in an abandoned factory not far from Kaide College, and was driven by curiosity to open it. Later, he found that this computer was running in a virtual world called Lyoko, and found a mysterious girl in the virtual world. Ren Jie named her Maya. Later Maya learned from the round tower that her name was Elita One. As soon as the supercomputer was turned on, a strange thing happened at Kaide College. If she does, Elita One will disappear. Ren Jie doesn't want this. He wants to find a way to get Elita One off the supercomputer. While Ren Jie was trying to find a way, Xia Zhinan continued to launch into the earth.

Comic version of the picture (8) attacks, and all kinds of things that threaten human life have happened. As it happens, Ren Jie met his classmates Chen Di, Li Qi and Yumi Ishiyama, whom Li Qi met in the gym. They * * * resisted Xia Zhina's attack. In order to prevent Xia Zhina from threatening the earth, Elita One must enter the round tower started by Xia Zhina and lock it. Only in this way can Xia Zhina's attack be stopped. In Lancome, Xia Zhina created many monsters (aggressive programs) to prevent Elita One from entering the Round Tower, while Chen Di, Li Qi and Yumi Ishiyama entered Lancome and digitized them with scanners to help Elita One eliminate monsters. Ren Jie operates computers in the real world and provides them with all kinds of tactical information. After successfully locking the round tower, Ren Jie will start the time reversal program to return the time to the state before Xia Zhina's attack, but only if there are no human casualties during Xia Zhina's attack and the time reversal program can't bring the dead back to life.
