Pingyu is forty miles away from Zhuge Liang's current camp, Zhuge Liang's army set off in the early morning, took half a day, and arrived near Pingyu County after noon.

Not far from Pingyu, Zhuge Liang led the army to march, walking, Zhuge Liang suddenly stretched out his hand to signal the army to stop.

Zhao Yun urged him to step forward at this moment, and said to Zhuge Liang: "Da Sima, a few miles ahead, it is the county seat of Pingyu, and Sima Yi's camp is stationed not far outside the South Gate. The night before I led my troops to attack the camp, I found that there was a high mountain not far ahead, and when I climbed to the top of the mountain, I should be able to see the situation in Pingyu County. ”

Zhao Yun knew Zhuge Liang very well, and knew that Zhuge Liang was cautious by nature, and would not rashly pull the army under Pingyu City, but first observe the clear shape. Therefore, it was suggested that Zhuge Liang go to the mountain in front of him to observe the situation.

"That's exactly what I wanted! Now that it is not far from Pingyu City, the soldiers can be ordered to assemble the return artillery, so as not to wait until the time when Pingyu is encamped, Sima Yi will attack us with the return artillery. Zhuge Liang nodded, turned over and dismounted, and gave the order to assemble the return cannon.

"Send someone to the advanced mountain to investigate, in case the Wei army is ambushed!" Zhao Yun waved his hand and sent scouts into the mountain to inquire about the situation.

After half an hour, the scout reported that there was no Wei army in the mountains and forests, so Zhuge Liang went to the mountains and forests under the protection of the generals.

The group climbed the mountain and looked north, and they could see the county seat of Pingyu several miles away.

Looking at Pingyu County, Zhuge Liang muttered: "Pingyu City is not a plain area, there are mountains in the north and east, barley in the west, and an open plain in the south.

Sima Yi's camp was built in the east of Pingyu City, with Pingyu City on the left, mountains on the right and behind, and only one side was enemy.

Since this is the case, our army went to the Pingyu City Xi'an camp and set up a camp, with the mountains in the north and the water in the west, so that only the southeast and southeast sides were attacked by the enemy. ”

Returning to the bottom of the mountain, the soldiers had already assembled the return cannon, and the soldiers were almost rested, so Zhuge Liang ordered to continue the march.

Wei military camp.

A soldier ran into the big tent of the Chinese army and reported to Sima Yiyu: "General, the Shu army is here, and now it is heading to the west of Pingyu County. ”

Sima Yi sat on his seat and closed his eyes in contemplation, listening to the soldier's words, the hand that was originally on his knee couldn't help but tighten, and then slowly let go. Sima Yi slowly opened his eyes and said lightly: "Zhuge Liang must go to the camp in Xi'an, and the generals will go out with me to have a look." ”

The generals followed Sima Yi to the outside of the gate, looked west, and saw the Han army encamped.

Among the generals, there were still many generals who wanted to take advantage of the Han army to attack when they were encamped, but when they saw dozens of return cannons discharged to the east and the Han cavalry patrolling around, they extinguished their thoughts of attacking the Han army.

Seeing the posture of the Han army, Sima Yi couldn't help but sigh and said: "Zhuge Liang is too difficult, he won't give me any chance at all." ”

There was a strong look of jealousy in the eyes of the first general: "Zhuge Liang also brought five thousand cavalry over, these five thousand cavalry are enough to be 30,000 foot soldiers." "Fortunately, the people of Yuzhou have moved to Yanzhou a few days ago, as long as I hold on for a while, we can also retreat when the people of Yanzhou retreat to Hebei."

Sima Yi watched for a while, and saw that there was no chance to attack the Han army, so he returned to the camp.

After the Han army established the camp, it was already night, and Zhuge Liang asked the soldiers and horses to be on guard, and he didn't do anything.

The next day, Zhuge Liang summoned the generals.

In the camp, Zhuge Liang frowned slightly and said: "Runan is the county of Yuzhou, and it is also the most populous county, and Pingyu is the place of governance, and there should be a lot of people around."

Yesterday I led the army over, but I didn't see many people on the road, our army has always put benevolence and righteousness first, and there is no shortage of food and grass, Sima Yi will not be strong and clear the wilderness to deal with our army. Uncle Zhi, you send someone out to inquire and find out what the situation is. ”

Generally speaking, there are two scenarios for using the strategy of Fortified Kiyono to deal with the enemy.

In the first case, the enemy is very brutal and likes to kill, and when encountering such an enemy, it is necessary to gather the people in a safe place and implement the tactics of fortifying the walls and clearing the wilderness to deal with the enemy. Otherwise, the people will suffer wherever the enemy goes.

For example, in later generations, when the Japanese army invaded China and swept away, our army often implemented this strategy to deal with the Japanese army.

There is also a second situation, where the enemy comes from afar, alone in depth, and there is not enough food and grass.

In the face of this kind of enemy, you can also use the tactic of clearing the wilderness with strong walls, leaving not a grain of grain for the enemy, and after a long time, the enemy will retreat on his own without food and grass.

However, the Han army was not brutal, would not do anything to the people, and the grain and grass were also sufficient, but the people near Pingyu were gone, and the Wei army's tactics of clearing the wilderness were a little wrong, which made Zhuge Liang suspicious.

However, Sima Yi did not intend to hide it, as long as Zhuge Liang had the heart to investigate, the matter of Wei's retreat to the north of the Yellow River would be known to Zhuge Liang sooner or later.

Chen Zhi gave up his hand and took the order: "The last general will send someone to find out!" ”

Zhuge Liang nodded and continued: "I am also an old acquaintance with that Sima Yi, how about the generals accompany me out to catch up with him?" ”

The generals smiled and said: "Since Da Sima is interested, I will accompany Da Sima on a trip." ”

"Since this is the case, I will gather troops and horses and go to Wei Zhai!"

After a while, the generals ordered 10,000 soldiers and horses and accompanied Zhuge Liang to Weizhai.

Because the Han army had cavalry, Zhuge Liang was afraid that Sima Yi would not dare to go out of the camp to reminisce, so he did not bring cavalry, only 10,000 ordinary foot soldiers.

Wei military camp.

"General, Zhuge Liang has come over with his soldiers and horses."

Hearing this, Sima Yi hurriedly asked, "Zhuge Liang is here?" How many soldiers and horses did he bring? Are the cavalry coming? Did you bring back the gun? ”

The first general replied: "There are only 10,000 soldiers and horses, and there are no cavalry, and no return artillery has been brought over!" ”

Hearing this, Sima Yi groaned: "I only brought 10,000 foot soldiers, and the cavalry and the return artillery did not come over, it seems that Zhuge Liang is not here to attack us." Prepare 10,000 soldiers and horses, and follow me out of the camp! ”

Sima Yi said, walked to the bronze mirror of the camp tent, and tidied up his clothes.

Seeing this, the generals couldn't help but be a little stunned, what did Zhuge Liang and the general have in mind?

When Sima Yi tidied up his clothes, another soldier came to report that Zhuge Liang had stopped 800 steps away from the camp, and 10,000 soldiers and horses had set up a formation, and Zhuge Liang sent someone to invite Sima Yi out of the camp to catch up.

Sima Yi led 10,000 soldiers and horses out of the camp and set up a position at the gate of the camp, and the two armies were 800 steps apart from each other.

In the middle of the Han army, Zhuge Liang sat on a four-wheeled vehicle, saw the Wei army on the opposite side out of the camp, and waved his hand lightly.

A cavalryman urged his horse out, looked at the Wei army on the opposite side and shouted: "My family's big Sima asked Sima Yi to come out to reminisce about the past." ”

As the cavalry was talking, two soldiers in the Han army pushed Zhuge Liang's four-wheeled cart and looked at the center of the two armies.
