Zhang Ke left the South Gate of the eldest son city in a gust of wind with his cavalry. Then, he left in the direction of the Southern family in Chenxi. Zhang Yang's 1000 cavalry were re trained by his original bodyguards after he was redeemed from Luoyang by Lv Bu. Although they can't compare with Lv Bu's Bingzhou wolf cavalry, they are also far better than ordinary cavalry, which can be said to be the elite of cavalry.

Zhang Ke is also a general who has been on the battlefield with Zhang Yang for a long time. From the first officer of Tunchang to the second officer of his own army, he also found out the seriousness of the matter from Zhang Yang's arrangement. So as soon as he left his eldest son, he divided the five hundred cavalry into five groups as he had been told, and they were five or six miles away.

After leaving the eldest son city for more than 20 Li, seeing that it was already bright, Zhang Ke ordered the cavalry to move quickly southward. All of a sudden, Zhang Ke was startled by the reaction of the cavalry of the first team in front of him. He saw that they turned their horses around and ran back. Some of them fell to the ground because of the rapid turn. But the cavalry immediately got up from the ground and quickly turned over and climbed onto their own horses.

Zhang Ke's team of 100 people was in the second position. Just when he was surprised, the head of the first village had already rushed to the front of him. He ran wildly while beating his horse, and at the same time, he cried out: "general, I found that there are thousands of cavalry in the Tang army! It's only three or four miles away from us

After hearing this, Zhang Ke's face changed greatly. Without hesitation, he ordered out loud: "hurry up, the back team will change to the front team, and return to the eldest son!"

After hearing this, the cavalry turned their horses around and ran in the direction they had come to the north. Zhang Ke knows that since a large group of Tang cavalry has appeared here, the worst situation that the governor expected has come. Most of the Tang army has entered Shangdang through gaopingguan. Now it is not important whether the fortresses of tianjingguan in the south are still holding fast.

At least to be sure, gaopingguan and Heshi county have been occupied by the Tang army, while Hao Meng and his 6000 troops must have been destroyed. Now the only idea in Zhang Ke's mind is to rush back to the eldest son city as soon as possible to warn the prefect.

As soon as the two cavalry fled and chased, they ran towards the eldest son city. More than ten miles behind them, more than ten thousand Tang soldiers, led by Tian Yu and Lu Zhong, were also coming towards the eldest son city in the north.

Tian Yu rode on his own horse, and Lu Zhong and Shi a followed him. After several battles, they both won a great victory, which made them very happy. Now for Tang and Zhao, they are all fighting for time. The area around the eldest son city is the most prosperous area in the Shangdang basin. If they can fight for the eldest son city before Zhao's reaction, it would be very important for Tang, The purpose of the whole war has been more than half.

While the three were chatting, suddenly several cavalry came at a gallop in the distance. Several cavalry kept running all the way to the central army where the three generals were. After arriving a few steps away, several cavalry stopped. One of them said, "report to the general. The order of the left general comes down. Our cavalry met the Zhao cavalry more than ten miles away. Now the Zhao cavalry is running north. General Zuo has led his cavalry to pursue. He specially ordered his subordinates to report to the general."

Three people listen to, all Leng for a while, Tian Yu reaction come over, toward cavalry a wave of hand way: "know, you wait to retreat!"

After the cavalry retreated, Shi alian said: "general Tian, since the eldest son city has been discovered, we should immediately return to Yu's family, and then first send troops to attack Gaodu, and then attack tianjingguan with the king's army on both sides, and then attack the eldest son after the king's army is joined into Shangdang."

"No!" Before Tian Yu could speak, Lu Zhong objected: "since Zhang Yang already knows, our army should take advantage of the situation to speed up and force Zhang Yang to go down to the eldest son's city. We can't give Zhang Yang more time. If we take over the king's army and attack the eldest son's city, Zhang Yang will be more fully prepared."

Tian Yu also nodded and said: "general Shi, general Lu is right. The faster our army is, the shorter Zhang Yang's preparation time will be, and the more favorable it will be for attacking the eldest son."

With that, Tian Yu turned to the messenger behind him and said, "the herald army, speed up the March and get to the eldest son city as soon as possible, and send someone to urge the equipment in the city to be sent to the eldest son city as soon as possible."

"No!"

After the messenger promised, he turned away immediately.

A moment later, the whole army sped up and headed for the eldest son city.

When Zhang Ke fled to the eldest son's city with 500 cavalry, he could not help but feel relieved when he saw that the city wall was ready. It seems that the Lord's defense is ready, but there are only 5000 soldiers in the city. Can they defend against the attack of the Tang army?

However, Zhang Ke didn't have the energy to think about it at all. The Tang cavalry behind him had already followed him. With a whistle, Zhang Ke led 500 cavalry to the north city. Instead of pursuing, thousands of Tang cavalry stopped hundreds of steps outside the city and quietly watched the General Zhao on the top of the city arranging soldiers Our defense.

In the evening, Tian Yu led most of the Tang army to the south of the eldest son city. After arranging for the army to camp here, the three men led their own guards to the bottom of the eldest son city and stopped at a place about 10 miles away from the city wall. Then, under the protection of the soldiers, they observed around the city, and then returned to their camp.That night, the general in charge of transporting siege equipment in the city escorted all the equipment and prisoners prepared in the city to the camp according to Tian Yu's requirements. As a result, the garrison on the wall of the eldest son's city saw countless torches entering the Tang army camp several miles away. At that time, they didn't know how many reinforcements had arrived at the bottom of the city, which made the garrison soldiers in the city very frightened. Even Zhang Yang was awakened by the noise in the middle of the night and rushed to the city to observe carefully. Unfortunately, it was late at night now, and it was too far away A few miles away, there is no way to know what happened in the Tang army camp.

After returning to the prefect's residence, Zhang Yang's brows were locked. As soon as he sat down, he said to LV Jiu and Zhang Ke, "is there a way to find out what happened just now in the Tang army camp?"

Everyone shook their heads. Since the cavalry of the Tang army arrived, they could not leave the city. At the beginning of the night, LV Jiu wanted to lead some subordinates to the camp of the Tang army to inquire about the intelligence. Who knows that before they got close to the camp, they were found by the shadow guard of the other party. After losing several subordinates, LV Jiu was able to get away, even himself Both of them have been hurt a lot. Looking at each other's posture, they should be very difficult people.
