Spiritual energy revives, the world undergoes tremendous changes, abilities are divided into hierarchies, the nine realms of cultivation are tightly guarded, and spiritual beasts and humans are in constant conflict. Student Lin Yuan was originally an ordinary boy, but during the awakening ceremony he gained level-less powers. He could infinitely superimpose his blood volume and freely switch between offense and defense. It was like a bug. From then on, his life was no longer ordinary. In the campus, he faced the gazes of his classmates and responded in a funny way; in the spirit ruins, he bravely fought the spirit beasts and grew up in the crisis. The heroine Su Yao and Lin Yuan are secretly in love and accompany each other ambiguously.
