Billions of years ago, at the beginning of chaos. The evil god of darkness controls the chaotic space, and Pangu splits the root of chaos, which is called the sacred red sandalwood tree. The root of chaos, the evil god of darkness, dies. The three realms appear, the red sandalwood sword comes out, and the three realms are in chaos!
The red sandalwood sword is the blessing of the three realms to those who are good.
With the red sandalwood divine sword, the evil one can destroy the three realms, and the evil god of darkness reappears.
