Dingxiang City has different passes from Yumenguan. Dingxiang City will be besieged on three sides, which is suitable for large armies to spread out. The only thing that will not be attacked is the southern city wall. There are many potholes around the southern city wall and it is a karst landform. If you are not careful, you will be killed.

You will fall into a pothole. The only access is the straight path from the south city gate. If you want to attack the south city wall, you must go around to the back of Dingxiang City and attack from the path!

With such a small road, the army cannot deploy at all, let alone attack the city!

This was also the way for the Tang army to retreat once they saw that the situation was not good, and it was also the purpose of the Tang army to build the city here.

But being besieged on the other three sides is not that easy, and it is naturally incomparable to Yumen Pass.

In Yumen Pass, Luo Zhang and everyone were sitting in a conference hall, discussing the situation of tomorrow's battle, and the spies sent out also collected the news here one by one to give Luo Zhang a judgment for tomorrow's battle.

Judging from the news we have now, the Tubo people did not evacuate, but set up camps farther away. However, the person in charge of the Tubo army and horses is no longer Lu Dongzan, but a different person.

The representative promoted by the big landowners and gentry is named Montu!

This man is also well-known in Tubo, he is brave and good at fighting, and he is not a simple-minded person with well-developed limbs. The fact that he can plot against Lu Dongzan at such a time shows his intelligence.

Although the commander-in-chief of Tubo had changed, Luo Zhang did not take it lightly.

According to the information gathered, after the Tibetan army and horses were gathered, there were still about 200,000 people. Compared with Yumen Pass, this number of soldiers and horses was still five times as many as Yumen Pass.

The current number of men and horses at Yumen Pass is only 40,000, including some who are injured, but whose actions are not hindered.

If these people were removed, there would probably be only over 30,000 people.

Fortunately, the 30,000 troops brought by Luo Zhang did not suffer many casualties. The real casualties were Zhang Hongyu's troops who originally defended Yumen Pass.

Luo Zhang had nothing to worry about whether he could hold Yumen Pass. There were still a lot of artillery shells, and although there were a few wooden bumps, it was not a problem to hold on for a few days.

As long as reinforcements arrive during this period, he can counterattack again.

With 30,000 cavalry, he dared to chase the Tubo people and flee in embarrassment. Give him more troops and horses, and Luo Zhang would definitely wipe out these Tubo people.

These are the elite of Tubo, and they are also the majority of Tubo's labor force. If this army can be annihilated, Tubo will definitely fall into civil strife. At that time, if Luo Zhang goes to attack with his troops and horses, he will definitely be able to annihilate Tubo.

Flat ground! Just like Gaoguli.

In Chang'an, after learning the news about Yumen Pass and Dingxiang City, Li Shimin has been looking at the huge map drawn by Luo Zhang hanging in the study.

After a long time, Li Shimin turned around and looked at Qin Qiong, Duke of Yi State, and Zheng Rentai, Duke of Tong'an County, who were standing in the hall. Both of them were strong generals who had followed him in his early campaigns in the north and south. Needless to say, Qin Qiong, Zheng Rentai was also extremely brave.

.

At this moment, calling the two people to the palace, it is natural that there is an order.

"Qin Qiong, Zheng Rentai listens!" Li Shimin said solemnly.

"Your Majesty, accept the order!" Qin Qiong and Zheng Rentai came down to pay homage at the same time.

"Qin Qiong, when the army is assembled, you will personally lead 100,000 troops to Yumen Pass to join Luo Zhang and counterattack Tubo!" Li Shimin said here, while the secretary on the other side quickly wrote the imperial edict.

By the time Li Shimin finished speaking, the imperial edict had been written and placed in front of Li Shimin's desk.

Li Shimin stamped the seal and handed the imperial edict to Eunuch Huang who was standing aside. At the same time, there was also a tiger charm. Without the tiger charm, the army and horses could not be mobilized!

Qin Qiong paid homage to receive the decree!

"Zheng Rentai, when the army is assembled, you will personally lead an army of 150,000 to the north, Dingxiang City, to assist Li Jing. If Dingxiang City is destroyed halfway, then support Li Jing and defend Dingyuan City! If Dingxiang City is not broken, then

Listen to Li Jing’s orders!”

"Your Majesty, take the order!" Zheng Rentai said with a solemn expression.

A sealed imperial edict and tiger talisman were also handed into Zheng Rentai's hands.

"Go ahead and rectify the army and horses outside the city. The army will arrive one after another in the next few days. We will strive to dispatch troops as soon as possible. Don't slack off!" Li Shimin waved his hand.

Qin Qiong and Zheng Rentai bowed to accept the order and retreated.

Looking at the two people leaving, the expression on Li Shimin's face was not as happy as when he received the news from Luo Zhang.
Chapter completed!
