Lantian Pass, the guard general Yan Pu stood at the highest point of the Guancheng, and the fog on the top of many mountains in his sight had been blown away by the wind.

The fog is relatively heavy, and at this moment it is still permeating all the ravines and valleys, and looking down from the highest point of the beacon, you can't see the outline of the ravine, only the surging fog.

He saw a group of knights coming from the north, waving flags on the half-slope, the mountain road was relatively slippery and not easy to climb, the defenders of Guancheng threw the rope down, and the knights who came grabbed the rope and borrowed their strength to step on the mud and go up the hillside, and under the observation of Yan Pu, they handed over the military information.

After a short time, the military officials under Yan Pu trotted to Fengsui: "Marquis Jun, Marquis of Jinyang led the army to help, and when the letter was sent, it was about in Lanqiao Pavilion, and now it is about in Lanxi." ”

Yan Pu climbed the ladder and walked down, now he was much fatter than back then, and he took the military book with his broad palm, and carefully examined the contents.

Zhang Hu ordered him to repair the camp in the middle of the valley road, so that Zhang Hu's tired army could rest quickly.

Lantian Guan Xiu is on the high ground on the hillside, and the resources that can be hoarded are limited, and the troops that can be stationed are also limited.

It is a very standard and normal tactical layout to choose a steep place to repair the camp in the valley passage under the pass, and use it as a horn with the pass.

Yan Pu hesitated in his heart, paced with this military order in his hand, and walked towards his barracks.

The top of the mountain and the ground of Sekiki have been dry due to the high terrain, direct sunlight, and wind.

Stepping on the dry, hardened ground, Yan Pu remembered that the hillside path was slippery and difficult, and he needed ropes to help him get up the mountain...... The slopes of the mountains are like this, and the road surface of the ravine should be more slippery, so Zhang Hu's department, who forcibly marched from the southwest valley to Lantian Pass, must be very tired and urgently need to rest.

It also means that if the Beifu soldiers try to make a surprise attack and sneak up here by stepping on the mud, they will also be in a state of exhaustion.

Without auxiliary tools, the Beifu soldiers wanted to attack Lantian Pass...... It's just delusional.

What's more, Lantian Pass has hoarded too many war preparation materials, and it can directly attack the Beifu soldiers marching in the ravine here, and if Lantian Pass is not pulled out, the Beifu soldiers will not want to pass through Lantian Pass smoothly.

Whether it was a stone or something else, it could slide and smash into the ravine road, attacking and interfering with the marching columns of Beifu.

Therefore, Lantian Pass is very important, either pull it out or detour it.

However, according to Zhang Hu's orders, the new camp can be repaired, which will disperse the garrison of Guancheng...... If the Beifu soldiers attack during this period, wouldn't they have suffered?

Unable to make up his mind in his heart, Yan Pu was a little afraid to obey this military order.

Over the years, I have dealt with Beifu soldiers, what are Beifu soldiers? It was the original colleague and robe Ze who were defeated, absorbed, and re-trained by the Han army.

This Han army, which was reorganized by former colleagues and robes, has made surprising moves in every battle, and it really can't be handled with common sense.

Can you refuse Zhang Hu's order?

Not to mention Zhang Hu's annoyance, in case Zhang Hu's department did not rest well and affected the combat effectiveness, Wu Zhen and Zhang Hu would definitely not mind cleaning themselves up.

What's more, it is difficult to refuse this order itself.

With a tangle in his heart, Yan Pu handed over this military order to Wang Xiong, the commander of the army, and expressed his attitude: "Uncle Yuan, I thought that the troops would be divided to build a camp...... There is a danger of attack. Although the Marquis of Jinyang has an explicit order, it is not easy for me to refute it. It's just that I have clashed with Beifu several times, and I know that Beifu is good at the use of strange weapons. ”

After Wang Xiong examined the military orders and thought for a while, Yan Pu gave up his right to decide: "Yuanbo can be ten times more than me, and now only Yuanbo will make a decision." ”

"Whew~!"

Wang Xiong's face was serious, and he got up and paced to think and weigh the gains and losses.

War is like this, looking heroic and blazing, in fact, it is a business, and you have to be careful with your calculations.

The worst-case scenario is to divide the troops to build a camp for Zhang Hu in the ravine, and at the same time be attacked by the Beifu soldiers, so that many of the defensive tactics prepared by Lantian Pass will not be used.

Beifu's capture of Lantian Pass meant that three days later, the main force of Beifu would be able to fight out of the pass in an orderly manner and reach the vast flat land of Luyuan.

At that time, it means that the overlord partial army will be cut off from retreating, and when the army's heart is shaken, there is a seventy percent probability that it will be defeated and surrendered by the Beifu partial army.

The second bad thing is that the garrison of Lantian Pass does not move, and after Zhang Hu's troops arrive, Zhang Hu's troops will build their own barracks...... If Zhang Hu's department is attacked during the period, although the defenders of Lantian Pass still have the strength to defend, there will be absolutely no good fruit to eat.

After Zhang Liao's death, the five Zhang Hu brothers were all generals, if the Lantian Pass defenders played their own small calculations, resulting in the destruction of Zhang Hu's department, after the war to study the development of the war, and then investigate the responsibility, no one can escape punishment.

Other good possibilities can be ignored, and the concern now is about these two possible negative things.

"The fog cleared before noon."

Wang Xiong first made a judgment based on the experience of this time: "The Marquis of Jinyang will arrive about noon, when the fog will clear and the vision will be clear. ”

Yan Pu followed his train of thought and gradually stabilized: "At that time, if there is an enemy situation, there must be a warning signal. ”

Wang Xionglu smiled: "That's right, although the Marquis of Jinyang is tired, but Beifu has come from afar, and he is also tired. What's more, the Marquis of Jinyang detected the enemy early, and the soldiers and horses were prepared, and the battle situation was reversed, or he could be ambushed. ”

"Okay, just Yuanbo."

Yan Pu immediately turned to the table, took out the coarse silk and laid it out, began to grind the ink, muttered the language for a while, and began to write a reply to Zhang Hu.

Though...... The probability of the Beifu soldiers attacking Lantian Pass today is not high, but Zhang Hu can lead his troops to forcibly march to Lantian Pass, so the Beifu soldiers naturally have the objective conditions for forced march.

When Yan Pu and Wang Xiong made the best decision so far and sent someone to deliver the letter, Tian Xin had already arrived at Hongshimen.

The mountain walls on both sides here are steep, like the door frame facing the sky, and because the rock wall is damp and red after rain, it is called the red stone gate.

More than 500 people scattered and rested in the whole forward army, Tian Xin sat on a stone, the shield was placed horizontally on his lap, he was still continuing to eat, and the others had finished eating and drinking in the previous fifteen-mile trip, and they were searching for mountain spring water at the moment to fill up the water hyacinth they carried with him.

The fresh water at the spring is often still drinkable, and there is no need to be too taboo about raw water.

In the rear, a steady stream of pro-army knights followed, and some horses dragged on charcoal and hay, and began to make a fire in a sheltered place to boil ginger soup.

Jiang Liang caught up with Tian Xin and handed over Xie Jing's official document: "Princess, the defenders of Anshan Plateau have been forced to land. The minister has sent people to build the Beichuan pontoon bridge, because the river is turbulent, the lack of trees around, can be completed at three o'clock in the afternoon. ”

"Four o'clock in the afternoon? This was slower than expected, with a pedestrian bridge and then a vehicle bridge. ”

Tian Xin gave instructions on the official document and said to Jiang Liang: "At one o'clock in the afternoon, the three guards of the Huya Army will cross the river, and they can no longer swim across the river, and the impact of swimming and contracting the disease will be far-reaching. You and Xie Jing should think of ways to speed up the construction of the pontoon bridge, don't pity the vehicles, dismantle it if you can, and speed up the construction of the human bridge. At two points, the human bridge should be built, first so that the Huya army can cross the river, and then the vehicles will cross the river. ”

Behind him, Yu Shifang wrote this extremely heavy verbal order on the folder, and after Tian Xinsao saw that there was no ambiguity, he immediately signed it, and Jiang Liang took it back to study it with Xie Jing.

At this time, the fog will not dissipate, and Tian Xin's sun lance will be inserted on the ground, but the specific outline of the sun is still not visible, and there is no shadow, so it is impossible to judge the exact time.

Tian Xin glanced at the stone cliff on the side, picked up the sun lance and climbed up, and soon climbed out of the fog obscuring range, and saw the Lantian Guancheng halfway up the hill in the distance, and also saw the pale sun.

The sun lance was nailed to the ground, Tian Xin picked up the compass to observe the time at the moment, pursed his lips, and the marching speed was half an hour faster than expected, which was a good thing.

Observe whether there is a Wei army beacon on the top of the surrounding mountain, and there is a beacon on the top of the second mountain in the north, and Tian Xin will retreat the same way.
