After determining the next plan and strategy, the Shu army immediately took action, the Huns' "prison tactics" have just entered the stage of implementation, although the pass fortresses everywhere have begun to take shape, but they are still far from the real defense system that is completely iron-barreled, which undoubtedly gives the Shu army a chance to break through its prison.

Around Gu Yuan, there are as many as a dozen newly built pass fortresses, each of which needs to be garrisoned, don't look at Liu Yuan's more than 100,000 troops, the momentum is aggressive, but the troops really allocated to the fortresses are very limited, and even overstretched.

A defensive ring was arranged around the valley, and the battle line stretched for hundreds of miles, if it was a Pingchuan area, Liu Yuan did not dare to hope that it could be surrounded, that is, the Shangdang land was narrow, and there were only a few passable roads between the lofty mountains and mountains, so that the Huns' "prison plan" became a reality.

In spite of this, each pass fortress can only be stationed with three or two thousand people, no matter more, Liu Yuan really can't be transferred, among the 100,000 troops, Liu Yuan has to ensure that there is a sufficient number of field corps, in addition, Shangdang County, Tunliu, Changzi, Xiangyuan, Gaodu and other county towns, also need to send troops to garrison, compared to the vast territory of Shangdang County, 100,000 troops are really nothing.

So when Liu Yin decided to concentrate his forces and pour a little bit to prepare for a forced breakthrough, the Shu army could completely gain the upper hand, and no matter which point the Shu army chose, it was the same.

Liu Yin set his sights on the Hanshan between Tunliu and the eldest son, the Hanshan Pass is an important passage in the south of Shangdang, connecting the east and west parts of Shangdang, as long as the Shu army can open the Zhaishan Pass, it can smoothly enter the designated target.

Now the Hanshan Pass fortress is under construction, the Huns sent 3,000 men and horses to garrison Hanshan, that is, to prevent the Shu army from flowing eastward, at the same time, the Hanshan fortress is also one of the thirteen fortresses of the Huns besieging the Guyuan Shu army, and it is the most important part of the Huns' "cage tactics" system.

Although the Hanshan fortress has a dangerous terrain, but its camp has just begun to be built, and the repair has not yet been completed, although the Huns drove a large number of Han people to build a new Hanshan fortress for labor, digging mountains and quarrying, carrying soil and transporting sand, and overhauling fortifications, but the progress of the project is slow, and it is difficult to complete it in a short time.

Not only this part of the Hanshan Fortress, but also all the construction of the pass fortress has such and such problems, the most serious problem that plagues Liu Yuan is the shortage of labor, due to the killing of the Han people in Shangdang, the number of Han people is decreasing sharply, and now Liu Yuan has recruited the Han people for labor, even if he has been using coercive means, forcibly to enslave the Han people to do hard labor, to build fortresses in various places, it will also be limited by the number of laborers, so that the pass fortresses everywhere have been far from the success of construction.

Therefore, Liu Yuan could only temporarily cobble together some troops and garrison them in and around the fortress to prevent the Shu army from taking the opportunity to break through.

At the same time, Liu Yuan also knew that the forces stationed in Hanshan were relatively weak, so he maintained an army of tens of thousands between Shangdang and Tunliu Zhucheng, which could reinforce Hanshan and several nearby passes at any time to prevent the Shu army from infiltrating eastward.

For Liu Yin, if he wants to break through the Hanshan Fortress, he must prepare in advance and not let the Huns find out, fight quickly, and take Hanshan before the Huns can react.

In order to achieve this goal, when the Shu army moved to the cold mountain, it was completely silent and quietly advanced, and when the Shu army drove to a place ten miles away from the Hanshan fortress, the Huns were also unaware.

Climb the high ridge in front of the cold mountain, Liu Yin can see the situation on this side of the cold mountain clearly, the mountain road winds like a long cloth belt, at the end of the cloth belt, you can see countless people are busy, due to the distance, these people look like ants, so small that it is almost just a black spot.

The Hanshan Fortress has begun to take shape, looking at the past from Liu Yin's side, the camp fences are connected and orderly, once the fortress is completed, this passage can indeed be sealed.

"Attack!" Liu Yin's expression was solemn, and he coldly gave the order to fight.

The soldiers of the Shu army, led by Gao Yuandi, launched an attack on the Hanshan Fortress.

Guarding the fortress of Hanshan, is a member of Liu Yuan's general Lu Ta, black and strong, like a black tower, it is said that Lu Ta can at least rank in the top ten among the Xiongnu generals, skilled in archery and horses, and has the courage of ten thousand people.

In several defense points, Liu Yuan did not dare to rely on the Qianren anymore, but sent his cronies to lead troops to garrison, and Luta was also a general that Liu Yuan trusted, so he would be entrusted with important tasks by Liu Yuan.

Due to the insufficient number of Han laborers and the high intensity of work, the construction of the fortress was very slow, which made the irritable Luta angry, and he personally supervised the work of the servants on the Hanshan fortress.

The fate of these Han laborers is very tragic, and the labor time of nearly seven or eight hours a day almost drains their physical strength, despite this, Luta still thinks that the progress of the project is slow, and vigorously uses a leather whip to greet the Han laborers, and all the Han servants who pass by Luta's side, ****'s backs are covered with bright red whip marks without exception.

Mining rocks itself is high-intensity labor, and the Han people work day and night, and those who can persevere are already good hands, and many Han people who can't stand the labor are so tired that they vomit blood and die.

But Luta doesn't care, every time a Han dies, he will drag his body out like a dead dog, in Luta's eyes, the Han people don't have any status at all, they are just a group of slaves, Luta can be treated however he wants, as long as Luta is happy, kill a few Han people, it's all a casual matter.

Today, Luta also looked at the two Han people who were not pleasing to the eyes, and as soon as they relaxed, Luta's leather whip came over, beating them to the flesh, and Luta scolded while beating: "These lazy guys, really damn it!" ”

However, before Luta could increase the punishment, a Hun soldier hurriedly reported to him: "General Qiyu, the big thing is not good, Shu people...... The Shu people are attacking! ”

Luta was taken aback, looked up, and couldn't help but gasp, sure enough, in front of the Cold Mountain Pass, the Shu army was already coming all over the mountains. (To be continued.) )
