Legend had it that a long, long time ago, when the war in the universe reached its climax, it was still difficult to determine the victor.
There was an ancient race that had developed a powerful killing weapon. It was said that once this weapon detonated above a certain space, it would release a powerful light wave attack.
The light waves were all-pervasive, and the energy carried by one beam of light was enough to blow up a planet with the highest defense!
The terrifying thing was that this destructive energy would not decline even if the target exploded. Instead, it would follow the planetary fragments and travel rapidly through the galaxy, continuously transmitting.
As soon as this news spread, all the creatures in the universe objected. However, the battleship carrying this great killing weapon still set off. It circled around the universe and finally disappeared. This great killing weapon was the Divine Rubik's Cube!
