"Alright, that's it for today. We'll come over and transfer the silkworms the day after tomorrow. Oh, during this period, we might need to come here often to watch over them, otherwise, the birds in the sky will eat all the silkworms. Second Brother, starting from tomorrow, we need to prepare more slingshots, stones, and the like. Whenever we see birds, we have to scare them away." Birds are the natural predators of oak silkworms, and if we don't keep watch, I'm afraid we'll suffer a big loss.
Everyone went to find slingshots and then picked up many small stones by the river. The stones by the water are generally more rounded and perfect for use as ammunition.
