Survival of civilization vs. Unknown erosion: On one side is modern human civilization represented by the "Great Xia Kingdom", and on the other side is the "mysterious forbidden land" that has descended on the world and has unknown rules. This is not a war between countries, but a challenge for human civilization to fight against high-dimensional existence for the sake of living space and future. The victory or defeat of the protagonist is directly related to the fate and vitality of the country. The name of the protagonist "Sword Immortal", as the video of the first battle went viral on the global Internet, became the hope and pride of the people of Daxia, and also became the number one target of research and fear in other countries.
