"We will exterminate the aliens in the valley before moving on."
"!!!"
"That many?"
"Should we really exterminate them? Can't we go around them?"
The girls looked concerned.
Nathan shook his head. "Unfortunately, it's not possible. The surrounding area has a lot of alien groups. If we loop around, we are bound to encounter any of them, and there's a high chance the aliens in this nest will come to us.
"When that happens, encircling us shouldn't be that hard with their number. On the other hand, if we completely abandon this area and loop with a much higher radius, the time it will take is not something I want to think of. There's also a chance of unknown variables to come.
"On the other hand, if we go straight by exterminating these aliens, we can create a path that we can use for the return trip as well. And only the groups near the hills will be coming toward us. I don't know if it's more or less, but it's more definite than fighting in other places.
