War Sima Yi

On this day, Zhuge Liang said to Xiao Zhuge, "Over the years, Sima Yi and I have fought with each other, mostly by tricks and ambushes. This time, it's time for us to fight fairly. Tomorrow, I will lead an army to the open field to meet Sima Yi. "

Zhuge said, "Good!"

Sima Yi was ecstatic when he got the news. He said to his men, "My ambush and strategy are not as good as Zhuge Liang." However, if array methods are involved, it is different. I have been familiar with the array since I was a child, and I know its mystery. I will definitely defeat Zhuge Liang! "

The next day, the two armies confronted each other on the Yuan Ye. Sima Yi rode out and said to the Shu army, "Please ask Zhuge Liang to talk!"

Zhuge Liang said to Xiao Zhuge, "Please push me over!"

Little Zhuge and a soldier pushed a four-wheeled cart and ran to the middle clearing.

Sima Yi turned over and dismounted, saying, "I've heard a lot about you and admired you!" Then he sat on the ground.

Zhuge Liang said, "Zhong Da, I think you have real talent and learning. Why don't you come to my country? Let's do it well! " !

Sima Yi smiled and said, "What does an old man like you want to do?"

Zhuge Liang said, "You have no ambition when you are old?"

Sima Yi said, "Why bother? Why don't you just retreat to Shu and have a good rest? I can also be at leisure. There are only a handful of old bones, and it has been several years, too many! Or you can come to us, and the two of us will sing poems and enjoy the plum blossoms together every day. How comfortable we are. Much more comfortable than riding a horse on the battlefield. "

Zhuge Liang smiled and said, "Then come to me. I also have wine and plum blossoms there, which is much warmer than this Wei country. Also, your master, does he trust you? I accidentally lost my head! "

Sima Yi said, "I am used to the northern soil and water, and I don't want to leave my hometown."

Zhuge Liang said, "Well, let's not talk about it. I haven't seen you these days. Has your military strategy improved? "

Sima Yi said, "Why don't I arrange an array and watch it?"

Zhuge Liang said, "Good!"

Sima yi gave a hand and the army immediately started to act. In a short time, it was put into a circular array.

Sima Yi asked, "Do you know this array?"

Zhuge Liang said, "This is a mixed array."

Sima Yi said, "Will it be broken?"

Zhuge Liang said, "If I know, I will break it!" "

Sima Yi said, "You also form an array, and I'll see if I can break it."

Zhuge Liang stood up and waved his hand, and the Shu army immediately set up its position.

Sima Yi said, "I sent men to break the battle. Goodbye. "

When Zhuge Liang returned, Sima Yi's army rushed over.

Sima Yi's army entered through the door in the lower right corner. With a wave of Zhuge Liang's hand, the Shu army suddenly changed, and there was no door at once, which immediately trapped the enemy. ...

Sima yi saw the Shu army changing ranks and didn't know what it was. He saw three Shu soldiers pushing a car. The Shu soldiers said, "Wei Jun's expedition was hard. I specially sent three ink pigs to reward Wei Jun. "

Sima Yi uncovered the quilt on the car, which turned out to be three generals sent by Sima Yi. Sima Yi sighed: "It seems that I can't compete with Zhuge Liang in array!"

Xiao Zhuge said, "Let the three armies charge!"

Zhuge Liang said, "All troops charge!"

The army rushed up at once, and Sima Yi's army had to retreat. Zhuge Liang said to Zhuge Xiao, "I'll give you 20 thousand, so hurry up and chase Sima Yi!" " "

Zhu Gejin said, "Yes."

Sima yi's army is fleeing to the camp. There is a canyon in the middle, which is relatively wide. One hundred people can walk in each row, and each row is two feet long. The canyon is six miles long and Sima Yi has 150,000 people. The marching speed is three miles every quarter of an hour;

150000 ÷100 =1500 (row)

1500× 2 = 3000 (feet)

3000 feet = 3 miles

60+3 = 63 (Li)

63 ÷ 3 = 2 1 (quarter of an hour)

Small Zhuge thought: If 20,000 people try their best, but they can't beat 150,000 people, they must reach the top first, so that they can shoot him.

Xiao Zhuge looked at the mountain peak and thought, the speed of our army is five miles every quarter of an hour. The place where we went up the mountain is in the middle of the canyon, and it takes 35 miles to get there. The peaks on both sides are semicircular, just forming a circle, and its diameter is the length of the canyon. There is a hill in the middle, so I can't ambush, so I can only lie on the plank roads on both sides, so I have to bypass the hill:

35 ÷ 5 = 7 (quarter of an hour)

60× 3. 14 = 188.4 (plum)

188.4 ÷ 4 = 47. 1 (Li)

47. 1 ÷ 5 = 9.42 (quarter of an hour)

9.42+7 = 16.42 (quarter of an hour)

16.42 quarter hour (2 1 quarter hour)

Absolutely.

Little Zhuge said, "Don't chase, all the army will go up the mountain!" "

At the foot of the mountain, Sima Yi's army is coming this way. Zhu Gejin ordered: "Archery!"

Sima Yi's soldiers could not escape and suffered heavy casualties. Sima Yi and a group of soldiers rushed out of the canyon and fled to the camp in Longxi.
