On a narrow pass, enemy supply wagons.
What should you do?
If the road was long, treacherous, and narrow, it was like two rats fighting in a hole: the braver one would win! Under normal circumstances, naturally, you'd kill the men and seize the grain.
There was nothing wrong with that approach.
But Kang Shi's goal wasn't the grain.
Before the battle began, Yu Zi had been puzzled. Her great-uncle had told her that if she didn't understand something, she should ask. "Isn't the strategist's goal to seize the grain? The enemy is risking so much, crossing mountains and valleys and hauling supplies through the night. That shows how important this shipment is. So why not take the grain now?"
Lin Feng, on the other hand, had caught on to the idea and ventured to speak up. "We aren't short on grain, so there's no need to seize theirs. The real goal is to stop the grain from getting through, so Linshan County can't receive these supplies? Does the strategist mean... we only need to kill the men?"
Kang Shi knew why his lord had sent the two of them over. He got along well with Chu Yao, so he wouldn't keep things to himself. And if time allowed, he didn't mind patiently teaching them. He said, "Kill them? Why go to all that trouble? Just destroy the supplies."
One of their tasks was to disrupt the enemy.
Achieving the goal was what mattered; the process didn't have to involve a direct confrontation. Kang Shi immediately showed Lin Feng and Yu Zi how it was done. First, he ordered men to lie in wait on the high ground and hurl down boulders. Then he advised Xianyu Jian to form ranks and bring down the mountain by brute force!
