Zhou Yu was jealous of Zhuge Liang's talent. When Sun Liu was running out of arrows, he deliberately ran up to Zhuge Liang and asked him to hand over 200,000 arrows in 10 days. This is impossible, but Zhuge Liang has a careful plan. In case Zhou Yu has other deadly tricks, he readily promised and told Zhou Yu that 10 days is not needed, as long as three days is enough, and a military order was issued.

In fact, Zhuge Liang knew that there would be fog on the third day, so he had long thought of a plan to borrow a straw boat and take an arrow, and there would be fog on the third day.

Zhuge Liang borrowed dozens of boats and hundreds of soldiers from Zhou Yu. The gongs and drums were all ready, and the mowers rushed to Cao Cao's boat to drum and shout, knowing that Cao Cao would not fight in foggy weather.

Can only shoot arrows to repel the enemy, and sure enough, Cao Cao did not participate in the war. He ordered Cao Bing to shoot back the enemy with disorderly arrows. Under Cao Bing's disorderly arrows, hundreds of thousands of arrows were all inserted in the grass man and spread all over the boat. Zhuge Liang estimated that there were already more than 200,000 arrows, and all the soldiers shouted Xie's arrows. When Cao Bing knew that he had been cheated, he had returned to Jiangdong Camp.
