 Five? Fifteen? We don't have enough parts to build more than three. If we need more than that, we'll have to rob the computer and the spaceship. And that's one thing I refuse to do. The spaceship is our only link with Earth until the next wave in two years. All right, then I'll tell you what we'll do. We'll floodlight the supplies at night. We'll post the guard with half-charged rifles until we can move to the new warehouse. That'll take about ten days. Meanwhile, our fast crops are ripening.
