It has been three days since I returned to Erlong Valley, and Jiang Chuan can be said to be so busy in the past three days that my feet do not touch the ground. The first is to resettle the more than 5,000 people who followed, which is the most important thing.

Naturally, the existing houses are not enough, but fortunately it is summer, so you can live in tents temporarily. This time, Jiang Chuan seized a large number of tents from Liaoyang City, and naturally temporarily resettled the people.

Originally, when Liu Ji saw this large number of people, he was first overjoyed, and then frowned, because so many people were going to eat.

But when he saw the large amount of grain that Jiang Chuan had brought over, his brows furrowed again.

With shelter and food, the minds of the 5,000 people quickly settled down and began to look at this new environment curiously.

In order to let these people integrate as soon as possible, Jiang Chuan sent people to invite Guan Sanye, Guan Hu and others, so that they could walk around and communicate with these new residents more often, so that they could better adapt to Xin Huangjing.

In short, in terms of civil matters, Jiang Chuan handed over everything else to Liu Ji after he explained a rough outline.

Through the observation during this time, Liu Ji not only made achievements in strategy, but also was indeed a good hand in civil administration, and thousands of people were stable and stable under his combing, without any major waves.

And Jiang Chuanzhi is responsible for providing logistics, asking for money for money, asking for people to give people, asking for materials for materials, and asking for food for food, these things are now sufficient, so basically Liu Ji is busy working alone. Looking at Liu Ji's tired look, Jiang Chuan was also a little reluctant in his heart.

Thinking that this military advisor was still tied up by himself from the thief's den with a knife on someone's neck, and now that he is here, people are conscientious about their work, which makes him a little embarrassed.

Of course, he also has his things to keep busy.

Although it is said that it is very majestic to go out this time, he killed 5,000 people and horses, captured 29 red-clothed cannons, and a large number of baggage, took advantage of the situation and took Liaoyang City, and captured countless people, and also captured a princess by the way.

However, Jiang Chuan also knew that the pressure brought by this majesty would soon become apparent.

This time, he not only succeeded in attracting the attention of the Manchus, but also definitely attracted the attention of the Ming army. Although the Ming army is weak, it is not a fool, and it will definitely find out what happened soon.

Jiang Chuan has a clear understanding of these consequences, so his main work in the past few days is to expand the army again and rectify the armament.

Only with enough self-protection ability can he carry the past when the Eight Banners army comes to take revenge. And Jiang Chuan believes that as long as he carries it through this time, the situation he faces will be very different.

Therefore, after careful consideration, Egawa did three things: the first thing was to expand and renovate the walled wall at the mouth of the valley. The original walled wall may be easy to defend and difficult to attack for a horse thief's den, but if you have to face the attack of tens of thousands of troops, it is a bit insufficient.

Therefore, Egawa decided to make a comprehensive upgrade of the entire Taniguchi's defense this time, and made Taniguchi's defense a well-defended and truly impregnable fortress.

Because it involves the secrets of the system, the entire Taniguchi location is blocked by a long wooden wall, and no one is allowed to enter or approach except for Egawa and the army.

Jiang Chuan knew that he would definitely leave a lot of traces when so many people came in and out, and his location would be discovered sooner or later, which he knew very well.

It's just that he hopes that this day will come later, so he sent a large number of sentry scouts in all directions, on the one hand to inquire about the news, and on the other hand, to hunt down and block the scout sentries sent by the Qing army or the Ming army.

While doing a good job of internal and external secrecy, Jiang Chuan also trained 1,000 engineers from the systematic engineering battalion for construction.

The efficiency of these engineers is very high, unimaginably high, far beyond the efficiency that a natural person can achieve, so there is not a single civilian worker on the entire construction site to help, all of them are system engineers and other types of troops.

Under the ultra-efficient construction of these engineers, the outline of the entire Taniguchi fortress is rapidly appearing at a speed visible to the naked eye.

The second thing is to expand the army. With this large number of seizures and the annexation of more than 5,000 people, Jiang Chuan expanded the number of crossbowmen to 3,000 in one go, and all the equipment was upgraded.

Not only are all crossbowmen equipped with iron armor that can defend against vital points, but the short swords at their waists have been replaced by long swords that use more hand-to-hand combat.

In future battles, these crossbowmen will be the main class of troops in defensive operations.

At the same time, Egawa's pro-guard force was also expanded to a size of 1,000 people, which was Egawa's core strength. Once the time comes to defend the city, once the enemy attacks the city wall, the personal guard is the last barrier on the city wall.

In addition, the spear team has also been expanded to 1,000 people, and all the original equipment and leather armor have been upgraded to iron armor, and long knives suitable for melee combat have been announced to be hung on their waists, which were captured from the Tartar barracks this time, and they came in handy.

Spearmen are also an important force in close combat, in the original system setting, spearmen without armor were used as cannon fodder, but after Jiang Chuan's redress, they have basically initially possessed the characteristics of hoplites. As long as you train well, you can be pulled out as a hoplite for field battles, or you can use it to defend the city.

In Jiang Chuan's eyes, there are no cannon fodder troops, garbage troops, and everything can be turned into the main force as long as there are enough materials and equipment.

With the last remaining population balance, Egawa expanded the number of heavy cavalry to five hundred, and no one was equipped with two war horses, one for riding during battle, and one for carrying heavy cavalry armor and weapons, so that they could maintain more physical strength when fighting and charging.

The above types of troops all need to occupy the total population, and by the expansion of Jiangchuan, the extra population is basically exhausted this time.

Fortunately, mercenaries don't have to occupy the total population, but they consume more honor points.

Fortunately, this victory allowed Jiang Chuan to gain more than 50,000 honor points, which was enough for Jiang Chuan to recruit more mercenaries again.

Therefore, Jiang Chuan expanded the archers to 5,000 men and horses in one go, and the light cavalry was also 5,000.

And using the large amount of captured Tartar equipment, the 10,000 cavalry was rearmed. All cavalry are equipped with iron armor, and although the defensive ability is not comparable to that of the heavy cavalry, it is a large improvement compared to the previous defensive ability.

And all the archers were also equipped with sabers, and they did not lose their combat effectiveness when it was necessary to fight in close combat.

In Jiang Chuan's vision, all cavalry will eventually become all-round cavalry capable of both long-range cavalry and melee charge. Of course, this requires long-term training, but this is one of his goals in the future.
