On December 6, Leng Zhuo's second and fourth brigades went south in batches and stationed in this hidden valley, and the falling snow covered all traces for them.

After all, at present, the four major brigades and regiments have formed their own command systems in the previous series of operations, and if a reorganization is carried out, first, it will not be possible to form combat strength in a short period of time, and second, it will be too time-consuming, not to mention that each military general has his own command characteristics.

For example, Han Xin, who likes to command large-scale mobilization of troops and horses, is not harsh on a single combat force, but requires his subordinates to absolutely obey the command, a typical commander-type general, and Xiang Yu, brave and unstoppable, must charge forward in every battle, is a brave general, charging into battle is a good hand, leading the army does not have to be much, but it is a fierce pawn.

Every military general has their own characteristics, and Leng Zhuo is not easy to point fingers, but he falls behind.

"My lord, you are looking for me!" Wu Ce came to the mountainside cave under the guidance of a soldier, but at this moment, the cave was expanded, forming several separate spaces, and Leng Zhuo naturally occupied the largest one.

Wu Ce glanced at the cadres in the stone room, but they were all the main figures of their self-organized division, two military divisions, two staffs, and the chief and deputy brigade commanders of the four major brigades, although Wu Ce was also a person who had been a brigade commander, but in this swamp division, he was only a battalion lieutenant commander.

People are under the eaves and have to bow their heads!

Leng Zhuo nodded, stood up, came to the table made of wood, tore off a piece of cloth on it, and revealed a fortress made of clay, which Leng Zhuo relied on his memory and shaped with mental power, and it looked similar to Yuntian Fortress, but this was just an appearance.

"I heard that you were the brigade commander of the Yuntian Division, and you were responsible for guarding the Beiguan Pass Wall that day, and personally participated in the battle for the wall, so I came to you to ask you some questions about the Yuntian Fortress, and I hope you can answer truthfully!"

Wu Ce nodded, Leng Zhuo and his party wanted to capture the Yuntian North Pass, Wu Ce was supported by both hands and feet, and only after opening up here, it was possible for Wu Ce to return to his original position, and only half of the Yuntian Fortress could not be called a fortress at all.

"I don't know what adults want to know, but everything I know, I will tell the truth and never hide it!" Wu Ce said.

Leng Zhuo nodded, and said: "This is the best, this model is made by me from memory, you see what are the differences, I know that there are actually many arrangements in the fortress, these are not known to me, these must be carefully explained by you, and in that day, you have participated in that battle, you should have some impressions of some Hu people's strong people, these people are likely to be stationed in the fortress, everything you can think of must be said, we can make a targeted plan to increase the chances of winning!"

Wu Ce sighed and looked at the model made by Leng Zhuo, basically, this model has already depicted most of the surface of the Yuntian Fortress: "This model made by the adult is very intuitive to make a section of the North Pass, but the adult must not have been to the top of the wall, so there are some arrangements that the adults don't know!"

Leng Zhuo nodded, the wall is a forbidden area, except for the garrison soldiers and horses of the Yuntian Division, they are not allowed to approach at all, although those places are not too secret, but for Leng Zhuo, a passerby who has only walked back and forth from the pass a few times, he basically has no understanding, and most of the people here are also like this.

"Because the North Pass is facing the grassland, so when it is built, it is much more majestic and tall than the South Pass, and there are countless various defensive measures arranged, in addition to the large arrow tower of fifty meters that the adults see, on the wall, there is a bed crossbow stone platform every ten meters, and a giant bed crossbow can be placed, and not all entities are in the wall, at the top, in fact, there is a crossbow arrow mechanism for dark shooting!"

"It is densely packed with arrows, which can be controlled by the mechanism, and if you load the arrows at once, if you fire them, you can cover the area of the wall from 50 meters to 150 meters, but this mechanism is a bit laborious to load, and if you want people to fall into the shaft, even if you are trained, it will take three minutes to complete a load!"

"In addition, under this arrow hole, there is a rolling stone exit every ten meters, which can be thrown into the rolling stone and fire oil from the top of the wall!"

"The average wall of Beiguan is as high as fifteen chapters, counting several giant round towers, the highest point is twenty zhang, and the top is more than seven zhang wide, and all of them are made of huge bluestone, even if it is the strongest thunderbolt catapult in existence, the thousands of pounds of boulder cannonballs thrown out can't shake one or two!"

"In addition, on the cliffs on both sides, there are actually a lot of hidden platforms, which cannot be seen on the ground, these places can be looked, can be used as arrow towers, even if they are attacked on the wall, the archers on it can also be shot one by one, so that it has no place to stand!"

"After closing the wall, there are three large warehouses in the Yuntian Fortress, two of the largest of which contain a large number of bed crossbows, catapults, spare armor, blades, as well as a large number of crossbow arrows, fire oil and other defensive equipment, and the other one is a small garrison fort, which is set up with a small grain depot, counting the space in the other two large warehouses, which can accommodate two thousand soldiers and horses!"

"It can only accommodate two thousand soldiers and horses?" Zhang Liang asked with a frown.

"I'm talking about normal living, if it's crowded, plus the other two large warehouses are emptied, you can also build a camp tent on the wall, and it is estimated that it will be no problem to accommodate 10,000 soldiers and horses!" Wu Ce said.

"If only 10,000 people can be stationed at the pass, counting the situation we investigated before, there are almost more than 10,000 Hu cavalry in Guanxia, then there are only about 20,000 soldiers and horses at the north pass of the Yuntian Fortress at the moment!"

This attack on Yuntian Fortress is not a problem of a small number of people, the empire's 200,000 soldiers and horses stormed the fortress with only four or five thousand people at that time, or two sides of the force, and in the end it was not taken, it can be said that there is no problem with the defense of Yuntian Fortress, the reason why the fortress is lost, to a large extent, is that no one would expect the fortress to be attacked, so the above arrangement is almost not launched!

No matter how powerful the defense is, it must be supported by someone to call it an impregnable wall.

Wu Ce licked his dry lips and continued: "Last time, Hu Wei dispatched a lot of strong people on the grassland to seize Beiguan, and one of the three-blooded Golden Wheel Holy Beast warriors of the Helabran clan came, and the Hera Bolan clan believed in the Hera Golden Great Beast, and the strong man in the clan had an incorruptible body, as strong as a dragon, and even more powerful, and incomparably powerful!"

"The female venerable of the Great Moon Clan, the mantis double blade in her hand, is extremely sharp, cutting gold and jade, and extremely flexible, and her strength is not much better than that of the powerhouses of the middle level of the Heavenly Spirit!"

"In addition, it is the most terrifying beast mad warrior in the grassland, this group of people are all born of human and beast intercourse, the body is very animalistic, as long as it is slightly provoked, it will fall into a state of rage, and it is the same as a mad beast, it doesn't know pain at all, only knows killing, and because it contains beast blood in the body, the vitality is extremely strong, and it is difficult to kill!"

"That's all I know, as for whether there will be other strong people of the Golden Clan in addition to the powerhouses of these two clans now, I don't know!"

"There's a lot of space in this warehouse, isn't it?" Leng Zhuo turned his head and asked Wu Ce.

Wu Ce nodded and said, "Well, the warehouse in the Yuntian Fortress has been excavated for hundreds of years, and the space is not small, after all, the rift valley is long and narrow, and the entire fortress is almost suspended on the cliff except for the north and south passes, and you can only find space from the cliff, so the excavation has never been interrupted!"

"This warehouse is the closest to the wall, and in terms of thickness, it shouldn't be thicker than the wall!" Leng Zhuo pointed to one of the rock walls.

Wu Ce snorted and said, "This, I don't know, but there shouldn't be, do you want to open a hole from here, and then enter? This is impossible, compared to the bluestone wall, this place is almost a whole, if you want to dig a hole, there will definitely be a huge movement!"

Wu Ce shook his head again and again from his subconscious, but speaking of which, he really didn't expect that according to normal people's thinking, they would think of a way from the north gate, instead of focusing on the mountain, but this seemed to be easier to break through than the wall, and the side facing the outside of the mountain wall had also become very thin after years of continuous expansion.

If the door of the warehouse is still ten zhang away from the north pass, plus the width of the wall, it is almost twenty zhang, and the wall is embedded in the cliffs on both sides, and it is necessary to add a few zhang of protrusions, but after so many years of continuous expansion and excavation, the inside of the warehouse is facing the north, and it is almost fifty meters away, and there are even a few guard towers together with the warehouse, which seem to be only five or six zhang away from the outer wall, less than twenty meters.

Leng Zhuo smiled, yes, the seemingly impossible passage is often a shortcut to success, attacking the Yuntian Fortress head-on, Leng Zhuo's more than 30,000 people are not enough to see at all, the huge wall as high as fifteen zhang is an insurmountable iron wall.

Repeating the re-enactment, the Hu people's seizure of Beiguan is estimated to be a failure.

If you want to gain a firm foothold on the wall in front of these countless Hu people, and then seize the North Pass under the siege of tens of thousands of fierce Hu warriors, even if Leng Zhuo has some masters in his hands, he doesn't dare to say that he can take it.

And the first step to win the North Pass is actually how to gain a firm foothold in the North Pass, and not be knocked down by the opponent all of a sudden, and it seems that it is difficult to have a good way without finding another way.

"There are 10,000 soldiers and horses on the wall, more than 10,000 under the pass, and this place is close to the swamp, if you hear the information, it will not take two days, there will be no less than tens of thousands of swamp soldiers to come, and after that, there is a steady stream of reinforcements, and there is almost no big chance of winning if you break through the pass head-on!"

Leng Zhuo glanced at everyone and said, "If you want to take here, I think the only way is to find another way!"
