Grass Boat Borrowing Arrows is a classic story in "The Romance of the Three Kingdoms". Back then, Zhou Yu deliberately made things difficult for Zhuge Liang and restricted him to build 100,000 arrows within ten days. Zhuge Liang looked up at the sky. Knowing that this was a harm to others, he calmly stated that it would only take three days. As a result, Zhuge Liang succeeded in "borrowing" 100,000 arrows through the foggy weather and Cao Cao's suspicious character, leaving Zhou Yu speechless. But why did Cao Cao prefer to shoot 100,000 arrows instead of shooting a rocket? Could it be that he didn't think well?
Actually, Zhuge Liang is very smart. He chose the time of dispatching troops at around 4 in the morning, when the fog was thickest and visibility was extremely low. On the other hand, Cao Cao was sensitive and suspicious. Seeing such a heavy fog, Zhuge Liang was sure to do something, but for safety reasons, he chose to close the camp and take defensive measures to prevent the enemy from attacking the camp. In addition, the soldiers in Cao Cao's camp are all wearing armor and ready to fight.
When Zhuge Liang's ship approached from Fang's secret whistle, Cao Cao couldn't see the enemy ship clearly through the thick fog, so he could only order the arrow to be released and strike in all directions. However, Zhuge Liang was worried about this. In order to concentrate on obtaining arrows, he kept beating the drum loudly so that Cao Cao could roughly judge his position. As we all know, when an arrow is tied to a cloth strip with fire, its lethality will be reduced, and the range will be shortened. In order not to waste the arrow, Cao Cao did not intend to use the rocket.
Secondly, the use of rockets in dense fog will expose one's position. Both sides fight in an environment with extremely low visibility. Whoever finds each other first will have the advantage. Naturally, Cao Cao will not take the lead. Exposure position. In addition, due to the fixed location of Cao Cao’s camp, he was not sure whether there were any flammable and explosive materials on the enemy ship. Once a rocket was fired, although it could ignite the enemy ship, if there was no one on it and it hit his camp straight, His camp is likely to burn into flames, and the gains outweigh the losses.
Third, the rocket is expensive and the cost is too high. During the Three Kingdoms period, sulfur and kerosene were rare materials, not as cheap as bamboo and feathers, and could not be used at will. What's more, because of the sudden incident, Cao Cao didn't have time to let the soldiers take out the kerosene and cloth strips and tie them to the arrows. Once the fighters were missed, the consequences would be disastrous. In addition, good steel is used on the blade, and the effect of using rockets on sunny days is unknown how many times better than foggy days.
The last point, Cao Cao doesn't like to use fire attack to win. At that time, Prime Minister Cao was invincible and invincible in the battle, with millions of soldiers, and he had the potential to sweep the world. If you need a fire attack to deal with the small Sun and Liu coalition forces, wouldn't it make the world laugh? What's more, Zhuge Liang is a master at playing with fire. Burning Bowangpo, Burning Xinye, Burning Chibi, and Burning Vine Armor are all his masterpieces. After winning, he himself said that playing with fire is not good and it is easy to lose life.
In fact, Zhuge Liang has already taken fire prevention measures. "Beitang Shuchao" volume 132 records: In wartime, the cloth curtains and cloth clothes on the boat were taken from the water and accumulated to aid flooding. Thieves have torches and rockets to cover them. Violators have ears. It is concluded that even if Cao Cao uses rockets, it is doomed to be in vain.
