This is the result of Qin Zicheng discussing with the deputy generals.

In order to avoid innocent sacrifices from the soldiers, they need to train these people together first, and the first group of people who meet the requirements will be the most likely to enter the Pioneer Camp.

Because according to their training intensity, if the person who can meet the requirements in the shortest time will be the bravest and strongest.

The Pioneer Camp also needs such soldiers the most.

The second and third batches will be allocated according to their expertise.

If you are good at hiding and have excellent observation skills, you can enter the scout camp and be responsible for collecting wartime intelligence.

By analogy, they broke up all these people and then entered the various barracks to continue to temper their training.

Because after the city wall is rebuilt, the border city defense has increased.

So General Qin Zicheng's military camp made another adjustment.

The Pioneer Camp remained unmoved and was still stationed in place. Whenever there was any movement, he attacked quickly.

Because the north and south directions were lengthened, Qin Zicheng divided the defense part into two battalions.

The two battalions rotate once a month, so that everyone can understand the terrain of the entire Jiayang Pass.

In addition to the defenses of these two places, Qin Zicheng has set up a mobile patrol battalion.

The patrol battalion is divided into two teams: inside and outside the pass.

As the name suggests, there are those who are responsible for patrols within the jurisdiction and those who are responsible for patrols outside the jurisdiction.

The so-called patrol within the pass is actually to be able to discover the insiders in time and to catch people out. Moreover, their patrol areas are larger, and even affect the areas where they trade.

The patrol outside the pass mainly sets up some invisible obstacles outside the city, requiring them to inspect these trap agencies outside the pass every day to ensure that their defense will not fail.

Qin Zicheng stood on the high city wall, looking at the flying sand of the loess below, and felt that he could strengthen his defense more steadily.

Song Lun had already looked around with an old man who was proficient in water conservancy.

The old man retired from the Ministry of Works. Because he had injuries on his feet, he retired and returned home in less than fifty years.

Unexpectedly, Song Lun invited him out again.

"Your Highness, we have a strong wind and sand here. Even if we dig a trench, it will not have any major effect. There is no water source. If we dig this trench, we can only install some barbs at the bottom, but the grass people think it doesn't have much effect. We also need to consume too much manpower and financial resources."

The old man said, then raised his hand and pointed, "Look, the defense line between the north and the south is too long. If we want to dig a trench out of thin air, even if the manpower is complete, it will probably take more than a year to complete the construction. But what after the completion?"

Qin Zicheng understood the old man's words.

This defense line is too long. Although there are mountains in the north, it can be said that it is a flat mountain from the foot of the mountain to Hongyang Pass.

They basically don't need to have too much defense to the north, but there is indeed something else to think of right in front of the city gate.

"Your Highness, digging a trench is not worth the loss. According to the opinions of the people, we should think of another way."

Qin Zicheng and Song Lun looked at each other, and felt that their previous thoughts were too naive.

If there is a source of water, after the trench is dug, there will be water directly inside, which will be a very perfect barrier.

But if it is just a ditch, it does lack some defense function.
