Luo Mu has had a rival since he was a child, Lu Shen.
Just because Lu Shen was there, he was always the second best in everything he did. Not only did he rank second in academic performance, but he could only get second place in competitions. He couldn't even grab a meal in the cafeteria as fast as Lu Shen.
Because of a fit of anger, they entered the forbidden area of University A - the strange building, but unexpectedly came to the world hundreds of years later.
Here, zombies are everywhere and humans are on the verge of extinction. They are forced to work together to survive in the apocalypse and find a way home.
