"Why is that?"

Fang Yun explained, "The teeth of goats are peculiar. When they graze, they eat the grass along with its roots. The more goats you raise, the greater the damage to the grassland."

"That's a strategy, but it seems insufficient to make a decisive impact," the general commented.

"This is just the first step. The second step is to purchase large quantities of grassland insects such as mantises, dragonflies, and ladybugs, all of which prey on pests, under the pretext of medicinal use. Within three years, the grassland will surely be overrun with pests."
