In 2050, the earth was filled with great resentment from human beings, which aroused the evil sword fairy who was originally sealed in the earth's crust.
But this is no accident - the old world's technology was highly developed, but its spiritual cultivation was far from adequate. Greed, hatred, fear, despair, and negative emotions accumulate on the surface of the earth to form "spiritual pollutants", and the Evil Sword Immortal is the embodiment of resentment, feeding on it and growing continuously in the seal.
In order to eliminate the evil sword fairy, the earth released soothing molecules, but they were interfered with and transformed into "genetically modified molecules" in the form of black mist - the only emotion left in the infected people's hearts was called: extreme.
Humanity has used the anti-gravity system to build seven huge cities suspended in the air: Xizhou, Shuoxing City, Yanyuansk, Canxing Castle, Woyuan City, Xiguang City, and Huicui City. These are the last refuges of mankind.
With the revival of the Evil Sword Immortal, the immortal heroes in the old world began to choose which inheritors with firm faith would pass on their power. However, using powerful power often requires paying a corresponding price.
The protagonist is the container developed by Xizhou that can contain the resentment of the Evil Sword Immortal.
