Keep Defending!
One by one, I jumped from one zone to another, wiping out endless locusts in cold blood. After taking a full tour through all the twenty zones, I returned back to the second zone.
I took almost one hour to do so, and when I returned I found the situation typically like what I expected.
The world was filled with endless dead bodies of the locusts, while the new ones were finding it difficult to move in between such weird gatherings of dead bodies.
Their number wasn't that high yet, and I estimated they'd need a couple more hours to end up forming a great army around my shields.
"Time to build more shields out there then," I didn't know how far this wave of energy reached, but I got the feeling that it went past the places I saved before in my staff.
I took out my staff and moved to the stored point here. As expected, the entire ground was littered with dead bodies of the locusts, while new ones were racing against time to reach my central region.
