The gate to the Broken Border was opened, and beasts infected by spiritual power invaded from foreign lands. The world gradually escaped human control. The world on the ground was submerged in yellow sand, and the concentration of spiritual power was getting lower and lower. Humanity's last weapons were slowly failing. Human beings were not allowed to transfer their living space underground. While seeking a way to survive, they were preparing to launch a counterattack against the alien creatures.
