The Portal Finally Appeared
I kept moving forward for five hours before I saw the early batches of the incoming forces. The enemy would never stop sending troops here. And I'd never stop sucking them dry!
I didn't use much bones for the upcoming hours. The cube's radius was always limited to one thousand miles at most, clearing all the enemies in that region.
After flying and doing this for five more hours, I finally reached a spot that needed me to move around, circling around this entire zone, clearing the enemy forces fast using my cube.
The cube would take five minutes to suck any living soul inside the one thousand miles radius. It might seem a losing bargain, especially when only double this time would let it cover tens of thousands of miles, but it was still profitable in regard to my bone consumption.
One hour passed, five hours, ten, twenty… I kept doing this forever until all of sudden, the entire world around me trembled.
