Eighteen thousand years ago, there were many immortals on the Blue Star, and geniuses emerged in large numbers. The four immortals Gu, Kua, Yi, and Wa led the Blue Star gods to engage in the "Yu" battle that shocked the past and the present. In the individual competition, they defeated the other heroes, seized the right to make the decision, and chose the battlefield of the final battle in the solar system Pluto. At that time, the strength of the Red Star in the Proxima Galaxy was far inferior to that of the Blue Star. If the Blue Star won this battle, it would be able to win an unprecedented award from the top management of "Yu" and rise to the top of the world, which was just around the corner. However, when the war ended, Blue Star was seriously injured. News of the death of Gu, Kua, Yi, and Wa came out one after another. Of the 100,000 immortals and gods who participated in the war, only a few returned with their broken bodies. And because the battlefield is in this department, countless immortals and gods are frantically extracting the source of the blue star in order to fight for their lives, causing the spiritual energy to become rapidly thinned. Eight thousand years ago, the current leader reluctantly decided to give up the current "Yu" war, and sealed the remaining spiritual energy in Kunlun, Penglai, Gushe, and Buzhou Mountains, setting up barriers to completely separate them from the outside world.
