Three years ago, Ling Yun, known as the Sword God, guarded the last base of mankind and stopped an army of millions of zombies with one person, and finally died from exhaustion. However, when he opened his eyes again, he found that he was reborn three months before the apocalypse broke out. In this life, he not only has to prepare in advance to deal with the crisis, but also needs to find the traitors who betrayed mankind in his previous life. Relying on his past life memories and sword god cultivation, Ling Yun vowed to reach the top again in the apocalypse and cut off all conspiracies and darkness.
