When Class 1 of Senior High School was in class, 45 students in the class and their coach Han Zheng were drawn into a different world. The first time I traveled through time was a campus where zombies were rampant. Zhou Leyan, who was originally weak and always lost, was forced to fight back because he was closest to the first zombie. He awakened the overt power "Life Tempering Body" and gained the hidden ability "Infinite Space".
After completing the task, they can return to reality, but the countdown will start again and they will randomly go to the next world.
From the zombie campus to the subsequent different worlds, Zhou Leyan led Jiang Lening, Lu Xiao, Tang Xiaoxing, Han Zheng and others to survive, become stronger, find ways to resurrect their companions, and gradually uncover the truth behind infinite time travel.
In the end, what he has to do is not just survive, but bring everyone home to attend his wedding to Jiang Lening.
