An invention of Zhuge Liang saved 100,000 troops in the Shu kingdom, and now the "traffic police" use it every day
Introduction: Today's society has made a lot of progress compared to ancient times, but this does not mean that the ancients were stupid, and some of the things they used, even after a thousand years, we still use them. Take the current traffic police, when they are on duty, they will almost always use this thing from the Three Kingdoms period. I believe that you must have seen it in life and should not feel strange.
Sima Yi and Zhuge Liang were both well-known courtiers of the Three Kingdoms, and they represented different camps, so they often fought. However, Sima Yi did not seem to be Zhuge Liang's opponent, but the Old Master always helped him. During Zhuge Liang's Fourth Northern Expedition, Sima Yi was almost killed by fire, probably because he was not stopped, and a heavy rain saved Sima Yi's life. Zhuge Liang also ordered the withdrawal of troops back to Shu because the supply of grain and grass could not be supplied.
Zhuge Liang was repeatedly defeated, the Vietnamese war became more and more courageous, and after preparing everything, he launched the Fifth Northern Expedition. This time, Sima Yi had a long memory and knew that he was not Zhuge Liang's opponent, so he ordered that the camp be strictly guarded. During this period, he received women's clothes sent by Zhuge Liang, and although he was angry, he could only bear it, because he had already heard about Zhuge Liang's diet and living, and concluded that he would not live long.
Looking at Zhuge Liang again, he had already calculated that his body was not good, but he wanted to complete the Northern Expedition in his lifetime, but he did not expect that Sima Yi could really endure, and the Radical General Law would not work for him. Zhuge Liang knew that if he delayed any longer, he would have to die on the front line, and in order to prevent the Shu Han army from being destroyed by Sima Yi after his death, he invented something before his death, ordering the army to scatter it on the road during the retreat, so that it could retreat unharmed.
One day, Sima Yi found that Shu Han had not moved, and when he inquired, he knew that they had returned with Zhuge Liang's body. They led their troops in pursuit of the Shu army, but when they reached the halfway point, they found that there were many Zamartins on the ground. The nails were made of iron spikes and were very sharp, and Sima Yi's cavalry suffered heavy losses and could only retreat. Sima Yi and Zhuge Liang had been fighting for many years, and he was not willing to let the Shu Han army escape from the front of his eyes, so he selected a thousand people and let them wear shoes made of wood to clean up the horse nails in front. However, there were too many nails, and Sima Yi cleared the empty space of the nails, leaving the Shu army with plenty of time to retreat. Sima Yi looked at the nail in his hand, where there was still the shadow of the Shu army, he could only leave sorrow in vain.
If zhuge liang had not invented this object, the Shu army would not have been able to retreat safely, and even if it retreated, it would have been pursued and killed by Sima Yi, and the losses would be very heavy. In the face of these horse nails, Sima Yi admired Zhuge Liang and praised him as a wizard! Now that a thousand years have passed, the zama nails that have made great achievements have become today's roadblocks. When the traffic police intercept the vehicle for inspection, it will be used to stop the vehicle from moving forward. For drivers who want to break through the traffic police line, as soon as the barricade comes out, the tire will burst, and where can they escape.
Conclusion: Zhuge Liang is very clever, he invented a lot of things, and many of them are still in use today, in addition to the horse nails, there are Kong Ming lanterns. Although the conditions were not as good at that time as they are now, it was still impossible to stop his fantastic ideas. It has to be said that Zhuge Liang's wisdom spanned time, and his invention not only helped shu Han, but also benefited today's society.
