A hundred years ago, eternal night suddenly fell, and a zombie virus broke out around the world. Eighty percent of living creatures were mutated into zombies, and all technological weapons became ineffective. In order to survive, humans could only pick up the most primitive weapons to fight zombies. At the moment of human survival, twelve humans suddenly awakened and became powerful warriors. They led humans to resist the attack of zombies and established twelve holy cities to preserve the human fire. All survivors formed a United Empire. From then on, there were no longer distinctions between countries. The protagonist, Lin Jie, was born unable to practice cultivation. He accidentally heard that there was an Invincible Fruit outside the Holy City that could change human physique. However, he was framed by a friend while picking the Innocent Fruit and was bitten by a zombie. He awakened the invincible plant system when he was dying.
