In this chapter, we learn that the enemy's physical body isn't strong enough to repel the pursuers. The only way to do so is to use all the means at our disposal. First, we need to figure out how to get rid of all the Lachters. We learn that there are 25 of them, and two of them are at the top of their game, so they're definitely not going to catch up to the chasers. So, first, they need to eliminate the entire Lachter force, one by one, so that they don't have to fight them all at once. We also learn that they can't see what's going on because the enemy is so far away. They can only see the edge of the wall, which is where they've been hiding. They need to engrave the edge with an "alloy blade" to make sure the enemy doesn't catch up with them.
