Ling Yao, originally a young man from the bottom of the earth, bravely acted for justice and traveled to China in the Marvel world. At first, he lived an ordinary life, until he learned that he was in the crisis-ridden Marvel world, and at the same time, the "Chinese Civilization Guardian System" awakened. The system is set up to gain training points by killing aliens and rewards for completing tasks to help him practice powerful skills. However, alien forces and super villains continue to hinder him from protecting China and the earth. He was initially weak and struggled in the confrontation. Not only that, his protective behavior has been misunderstood by some people, and he faces a crisis of trust. But with the help of helpers, Ling Yao grew rapidly. When the Purple Sweet Potato Spirit snaps his fingers, he protects China with the Zhoutian Star Formation. In the end, with his powerful strength, the alien forces and super villains who invaded Blue Star had to bow their heads.
