Two days quickly passed.
Near the star system of Mosmo Planet, a gigantic Titan Battleship hovered in the starry sky.
At this moment, numerous robots and "engineers" in protective suits were floating above this gigantic Titan Battleship, constantly installing something.
Additionally, the star equipped with a Dyson sphere-like device was now charging a huge machine.
This machine resembled a cabinet, the difference being that it had many slots on it.
And on those slots, there were black crystals the size of marble slabs.
Whenever energy was transmitted to the black crystals, they emitted a faint glow.
These black crystals are special energy storage crystals, capable of storing vast amounts of energy.
One crystal filled with energy is enough to power Earth's humans with electricity for 660,000 years.
Thus, it is evident how advanced these energy storage crystals are.
