Human beings were attacked by the four-dimensional civilization and fled to the depths of the universe to battle wits with them. There were spies secretly sneaking into the depths of the base, there were lone heroes who bravely broke into the enemy's formation, there were millions of troops confronting each other head-on, tearing apart the pretense of peace. Who has the upper hand, good or evil? This battle lasted for more than a million years, with countless casualties, and who won the victory.
