Zitong county was established in the Qin Dynasty.

In Zitong County, the terrain is higher in the northeast and lower in the southwest, while in the middle of Zitong County, there is a low concave Tongjiang River Valley. Zhang Lu's route to withdraw is to move from the southwest, from the northeast and from the low to the high.

Zhao Yun led his troops to ambush in the Tongjiang River Valley in the middle of the country.

It's June and it's hot.

The water of Tongjiang River also began to rise sharply. Although the river is not turbulent, the water shoreline is much higher.

Zhang Lu's army had to cross the Tongjiang River to go north.

Zhao Yun and Lu Su chose to intercept on the North Bank of Tongjiang river.

On the north bank, in a mountain forest.

The army is stationed!

Zhao Yun and Lu Su lived in the mountains, and the soldiers in the army were waiting.

"Chaka! Click

Feet in the woods, sound.

A soldier quickly came to Zhao Yun's position and reported: "general, there are sentinels in the rear to report the news."

"Bring it here!"

Zhao Yun said directly.

Lu Su said: "the Lord's sentry has arrived. It seems that the war in Chengdu is over."

Zhao Yun said: "there is a lord in Chengdu, as well as Huang Hu, Sha Moke, Chen Zhi and others. There is no suspense about this battle. I just don't know if Zhang Lu will be defeated on the spot. If Zhang Lu loses on the spot, it's really disappointing. "

Lu Su chuckled and said: "general, no matter how incompetent Zhang Lu is, there are nearly 50000 soldiers. This force is not easily defeated. Even if Zhang Lu is defeated, it is not easy to defeat so many soldiers. "

"I hope so," said Zhao Yun

Lu Su said: "is the general worried that there will be no war?"

Zhao Yun laughed and said, "wenpin has gone to Hanzhong. With his strength, he can easily capture the empty Hanzhong. Obviously, wenpin is sure to make contributions. And Zhang Lu is bound to lose in the face of the Lord. Once Zhang Lu faces the Lord, he will be completely defeated and captured. What else can we do? You can't get any good. "

"Then how can I win the reward for the soldiers after this war?"

"So we have to hope that Zhang Lu will lead the soldiers to escape."

"Only when Zhang Lu escapes, can we have a chance to capture Zhang Lu alive and win in one go."

As a general, Zhao Yun not only considers the overall situation, but also the situation of his soldiers. If the soldiers are not benefited in this battle, how can they fight bravely and fearlessly? If the benefits are won over by other armies, the soldiers under Zhao Yun's command will certainly have opinions.

Therefore, Zhao Yun hopes that Zhang Lu will escape.

Lu Su nodded slightly and said, "general, Zhang Lu is sure to come. It's not easy for the Lord to take down Zhang Lu in one go. "

"Rustle!"

A burst of footwork came, and the sentry sent by Liu Xiu came.

Zhao Yun said: "do not salute, let's say, what's the situation in the rear?"

The sentinel answered with a fist: "Liu Jingzhou has defeated Zhang Lu, and now Zhang Lu is on the run."

After a brief introduction, the sentinel took out a letter from his underwear and handed it to Zhao Yun. This letter is still sealed with fire paint and has not been blocked.

Zhao Yun tore up the letter and took it to check.

After he looked at it carefully, a smile appeared on his face and handed it to Lu su.

Zhao Yun looked at the sentry and said, "go back and tell the Lord that Ben will be ready to defeat Lu su."

"No!"

The sentry got the order, turned and stepped down.

Lu Su, with a smile on his face, said, "general, the Lord has released more than 10000 prisoners this time and told the soldiers about wenpin's attack on Hanzhong. This is a wonderful move! In this way, Zhang Lu's army must have lost their heart and never wanted to fight again. Even in order to get back to Hanzhong, Zhang Lu would go at full speed regardless of the cost. We will win this battle. "

Zhao Yun said: "yes, Zhang Lu has lost his family. Under such circumstances, it would be a shame if Zhang Lu could not be defeated. "

Lu Su thought about it and said, "I don't think it's appropriate for us to ambush Zhang Lu on the north bank."

Zhao Yun said, "why?"

Lu Su simple way: "too guard!"

Zhao Yun's sword eyebrows picked, and a look of meditation appeared on his face.

Lu Su said: "once the fleeing soldiers return to Zhang Lu's army, there is no need to consider that Zhang Lu's army will never be able to unite again. At that time, Zhang Lu himself is a dog who has lost his family. He is in constant fear. "

"For such a large army, we only need to attack them head on and force them to places where they can't escape. We are now stationed in the north bank, where most of the soldiers lie in ambush, and there are troops in the south bank waiting for us to defeat Zhang Lu. ""It's certain that we can defeat Zhang Lu, but it's too slow."

Lu Su's expression was solemn and said: "even once Zhang Lu retreats and runs away in other directions in the process of escape, it is difficult for us to capture Zhang Lu alive. Although Tongjiang river is good and a good place to stop Zhang Lu, there is no need to be so safe. "

Zhao Yun asked, "where are you going to set up an ambush?"

Lu Su waved his hand and asked the soldiers to bring the map.

This map belongs to Zitong county. Lu Su's hand is on the southwest entrance of Zitong county.

In this area, the terrain is relatively flat.

Many places are open plains.

Lu Su pointed to one of the hillside shapes and said, "I have observed this place at the junction of Zitong county and Fu County. It's called the Tian River Valley. It's said that the Tian river once tilted and washed into a valley, so it's flat all around and there are few hillsides and woodlands. It's an excellent place for fighting. "

"We will withdraw our troops and stay in the northeast of Tianhe Valley leading to Zitong county. At the same time, ambush troops in the southeast and southwest, leaving only the northwest. "

"On this day, although the valley is flat on all sides, it is in the northwest. Although the ten mile road at the beginning is flat, the more you go to the northwest, the more the valley is. In the end, it turned out to be the bottom of a mountain and valley, unable to climb, but stuck in it. "

Lu Su's eyes were sharp, and he said: "we buried ambushes on three sides, waiting for Zhang Lu's army to enter the Tian River Valley. At that time, we will lead our troops out from the north and East. "

"It's impossible for Zhang Lu to retreat, but if we retreat, our ambush at the southwest entrance will be enough to cut off Zhang Lu's retreat and let him turn around and retreat again."

"Once Zhang Lu retreats to the northwest, we will pursue him directly."

"Once Zhang Lu retreats to the southeast, the southeast army will kill him again, and Zhang Lu can also be taken as an example in the northwest."

Lu Su looked confident and said: "since we want to defeat Zhang Lu, we need to capture Zhang Lu alive. This is the most appropriate way. What do you think, general? "

Zhao Yun smell speech, the face also has a smile, way: "good, so do."

As for Lu Su's suggestion, Zhao Yun had no reasoning at all. He knew that the plan could be carried out.

Because now Zhang Lu is already defeated and can't bear the first World War. For Zhao Yun, it's how to beat Zhang Lu, not how to beat Zhang Lu.

Lu Su said with a smile: "general, we have to speed up. If Zhang Lu's army retreats to Tianhe Valley first, all the plans will be in vain. "

Zhao Yun nodded and said, "come on!"

A soldier came up and stood with a bow.

Zhao Yun ordered: "summon the troops to retreat and retreat to Tianhe Valley in Zitong county."

After an order was given, the soldiers in the forest on the north bank moved quickly. Under the leadership of Zhao Yun, countless soldiers went out of the mountains and crossed the Tongjiang river. Then Zhao Yun joined up with the army on the south bank and made a quick march.

Nearly 30000 troops were on their way, mighty and fast.

In order to arrive before Zhang Lu, Zhao Yun ordered his soldiers to rush day and night, and in a day and a half, they had already arrived at the Tianhe valley. At this time, Zhang Lu's army had not arrived.

Zhao Yun in accordance with Lu Su's plan, quickly arranged down.

After everything was arranged properly, Zhao Yu took Lu Su to look at it again in all directions. After confirming that it was proper, Zhao Yu returned to the northeast direction where he led the army to ambush.
