Under the surface of modern civilization, there is a global consensus barrier called the "curtain" - the official paranormal organizations of various countries have joined forces to conceal all paranormal events, abnormal beasts, and pollution disasters from ordinary people.
The essence of the curtain is the shackles left by the ancient gods in ancient times to seal the "Lord of Ten Thousand Gates", the ruler of the past. The power of the Lord of Ten Thousand Sects seeped into the human world through the cracks in the seal, forming "source pollution", giving birth to the extraordinary sequence system, and also created countless abnormal beasts and crazy polluters.
The fate of the Sequencer is a race against madness: the closer to the peak of power, the closer to the indescribable abyss, and the easier it is to become a puppet of pollution. The survival of human civilization depends entirely on a group of people walking in the darkness, using their flesh and blood and reason to cling to the world behind the curtain.
