When the war in the north was going on, Li Xin had already led 20,000 pro-troops to quietly rush to Shangdang, where he and Liu Xiaohai watched the war together. After the military order, although the whole army moved, not all the large armies acted together.

After all, once this kind of war starts, if all fronts start fighting at the same time, some new problems are likely to arise. Not to mention anything else, it will be very difficult to grasp the situation of a battle alone.

Another one is that for the center of the imperial court in charge of logistics in Chang'an, the pressure will definitely be unprecedentedly strong.

So, it's a good choice to start with a relatively easy place to start in the north, and then see the effect by the way.

Facts have proved that after three years of rest, the Tang Army can indeed fight a big war. On the contrary, although the Yan army has also recovered for three years, it is even less of the Tang army's opponent.

In just two months, the entire northern part of the river has been completely taken, and the conclusion is that it is the right time to destroy the Yan.

"Looks like the time is almost there!" In Huguan County, Li Xin, who had just received Liao Chuan Peng Lin's recital, said to Liu Xiaohai beside him. And behind him, there are also Deng Qiang, Zhang Hao, Hong Yi and other generals.

"Murong Chui wants to rely on the water and the water to block Liao Chuan and them from going south, if our strength is only this, he will definitely succeed. But this time, we came out with all the strength of the country, and it was not easy for him to rely on two rivers to stop us! Liu Xiaohai responded.

"Yes! Liao Chuan: They may be blocked for a while, but that is when we don't do it. Now, they have played a good situation, let's do it now, just enough to break the game for them and open the channel for them! After Li Xinhe paused, he nodded, quite satisfied with the progress now.

According to the news, now Huanwen is in Xuzhou, and it has gradually gained an advantage. The Yan army led by Fu Yan, Yue Ming and others was gradually forced to retreat to the vicinity of Tancheng County, Donghai County. The Yan army in the area east of Qiaojun, Chenjun, and Yingchuan was also thwarted in its southward offensive under the counterattack of Huan Huo, Huan Chong, Yuan Zhen and others. Judging from the overall situation, our actions at this time should be just in time for Yan Guo to be at its weakest! ”

"Murong Ke is not an ordinary person after all, if someone else is in charge, I am afraid that the entire Yan Kingdom will be a mess now, where will he continue to send troops and horses to the front line to support. Yang Lu went north and took away an army of 100,000, and then, two days ago, King Mu of Beihai brought an army of 100,000 composed of slaves and tenants to the south to support Huangfu Zhen and them. It seems that all the sources of troops in the hinterland of the Central Plains are almost exhausted, and we will not face too many enemies after all! Li Xin said lightly.

Anyway, the fewer Yan troops left north of the Yellow River, the more beneficial it would be for them. Of course, Li Xin also had some confusion about the fact that Murong Ke was able to send 100,000 troops south to support Huangfu Zhen at this time, and it seemed that the Jin army must be repulsed.

After all, even if these soldiers and horses were not sent south, Huan Wen would at most hit the previous border, and it was unlikely that he would make a greater breakthrough. Because if Huan Wen wanted to take the entire area south of the Yellow River, it would be impossible with the current strength in his hands.

In particular, Jiangzuo's cavalry could not compare with the Yan army, and the siege battle was protracted and time-consuming.

In this case, Murong Ke only needed to order Fu Yan and them to slowly retreat to the original counties, and then take a firm strategy, basically speaking, he would be able to defuse Huan Wen's offensive.

"Your Highness, please give the order! The soldiers have been waiting for a long time, just waiting for your order to march! Liu Xiaohai bowed and said.

"Your Highness, please!" Deng Qiang and the others bowed down in unison and said.

"Okay, then let's go our separate ways! According to the previous plan, the prince led the army and the flying dragon horse, and went out of the mountain from Jingcheng to attack Tumen Pass and Shiyan Pass, and first solved Murong Chui's department with Liao Chuan, and then immediately turned around and went south to Yecheng. ”

"Liu Xiaohai, you led an army of 50,000 to the party from Fukou, Malingsai, Junji Pass and Qishui Pass, and attacked Yecheng, so be sure to give me Murong Ke's attention firmly over there. Then, when the war in the north is over, this king will lead Liao Chuan and them to join you and take Yecheng in one fell swoop! ”

"Then order Zhao Ji and Chen Kang to advance eastward along the Jishui River, and attack the emperor Fu Zhen Yu Chenliu! He was especially told not to fight with Jiang Zuo's soldiers and horses, but he must not let himself suffer! Li Xin took a deep breath, and then gave the order to march to the people behind him.

"The last general commands!" The generals responded in unison, as if roaring.

On June 15, Li Xin officially led the army from Leping County out of the old pass and the old pass, and passed through Jingcheng out of Taihang Mountain to Shiyan Pass. There are two passes at the east entrance of Jingcheng, the west is Shiyan Pass, and some of the east is Tumen Pass.

The road is not easy to walk, but there is no way to do it because of the march. Tang Jun's appearance at Shiyan Pass was not an accident for Yan Jun.

Yan Jun, who had already been on strict guard, immediately reported the news to Yang Lu in Zhending County and Murong Chui in Anping County, Boling County.

However, at this time, they didn't know that the soldiers and horses at this expense were led by Li Xin himself, because Li Xin deliberately hid his Daxu honor guard and other things. After all, you want to achieve an unexpected effect.

Otherwise, once Murong Chui and the others knew that they were personally attacking Shiyan Pass and Tumen Pass, they were afraid that they would immediately adjust their deployment.

In terms of military talent, Yang Lu is not a good general, and his talent and ability lie more in politics. In comparison, Murong Chui's military talent is much higher than he doesn't know.

Therefore, Li Xin is using his own horse to fight Yang Lu's horse, using the principle of Tian Ji horse racing, and strive to solve the war in the south of Changshan County in the shortest possible time. Then, he directly waved his army eastward to attack Murong Chui and others in Boling County.

At the same time, Liao Chuan and others, who were in the north of Lushui, also received Li Xin's order and knew his plan. So, he and Peng Lin ordered the army to cut down trees on a large scale and make it look like they were going to build a bridge to cross the river.

Every day, the trumpets are sounded, the drums of war are beaten, and the appearance of a faction is going to attack in a big way. What's even more powerful is that they used the advantage of the cavalry in their hands to constantly mobilize soldiers and horses, which made Murong Chui's entire defense line very nervous.

Although Murong Chui was very worried about the Tumen Pass, he had to deal with the urgent documents sent from the garrisons of the cities along the river.

Anyway, it seems that a large number of Tang troops are about to attack near every county seat, which makes him have to sit honestly in Anping County, and he does not dare to stay away for a moment.

Just after Li Xin led the army to act, Liu Xiaohai also officially assigned the generals, respectively from Fukou Cheng 30,000 troops, from Junji Pass and Malingsai also sent 10,000 troops. Then he sent 10,000 troops from Taihang, and cooperated with Lü Guang's soldiers and horses at Qishui Pass, and went north to attack the Yan army north of Qishui.

As soon as the soldiers and horses of Hanoi County moved, Zhao Ji and Chen Kang of Xingyang and Henan County also immediately took action. The soldiers and horses had already been prepared, and at this time, Chen Kang led 20,000 troops to attack along the south bank of the Yellow River to the north bank of Jishui, preparing to rush north from the confluence of Jishui and the Yellow River.

Zhao Ji led an army of 30,000 to attack the Yan army at the confluence of Suishui and Jishui. After crossing the river from here, you will face the 50,000 army led by Huangfu Zhen of Xiaohuang County.

By this time, wars were already waging in various places bordering the Tang Dynasty and Yan Kingdom. With the armies in unison, the scale of the war was unprecedented, far more than any previous one.

Especially such an all-front offensive operation, it seems that the Central Plains Dynasty has not been in the past few hundred years.

As a result, the various defense lines of the Yan State were in an emergency, and the generals in charge of defense were facing great pressure from the Tang army. And Murong Ke and other officials in the imperial court, facing the urgent documents that flew like snowflakes, were also in a hurry, because they really didn't know what place to save first.

In contrast, the pressure on Huan Wen's side has been greatly reduced, especially in the area of Yingchuan and the southern part of Xingyang, Huan Huan Chong Yuan Zhen and others, at this time, after hearing the news that the Tang army sent troops to attack Huangfu Zhen, they couldn't help but breathe a sigh of relief.

Because the soldiers and horses of the Yan army, who were fighting against them, received the news that the Tang army was attacking Chenliu, they immediately dispatched a part of their soldiers and horses to advance northwest along Suishui, preparing to attack Zhao Ji's department from the flank.

After all, the soldiers and horses of the Yan army in that area are not particularly far from Xingyang County and Zhongmu County. Especially when there are no mountains and dangers in the middle, it is also a good way for the Yan army to support Huangfu Zhen's side in this way.

Back to Li Xin's side, Tumen Pass and Shiyan Pass are about ten miles apart from each other, it is located at the southern foot of Baoqi Mountain, the south is the West Mountain, and there is exactly a passage between the two mountains, and the two passes are the east end and the west end respectively.

And the cliffs around this Baoqi Mountain, but the top is flat, just blocking the main road of Taihang Mountain out of the North China Plain.

After leaving Taihang, to enter the North China Plain, if you take the Jingcheng, you must pass between these two valleys.

Back then, Han Xin's last battle took place in this place. In order to confuse the enemy, he ordered his soldiers to hold a flag and look at the Zhao army from the top of the mountain, which made the Zhao army panic because they thought that the Han army had a large number of troops.

Now that Li Xin is leading his troops to Shiyan Pass, he naturally does not plan to learn the allusion of the last battle, and the Yang Lu is not Chen Yu of Zhao Guo. But Li Xin and Han Xin faced the same situation, that is, the road was blocked by the enemy.

However, Han Xin has a backwater to defeat the enemy, and Li Xin also has his own clever plan.
