The area of the infantry barracks is the largest, and the fortress-style wall on the periphery is almost 100 square kilometers, and it is basically no problem to accommodate 100,000 soldiers to eat, drink and Lazar.

Under the escort of the personal guard battalion, Hong Tiancheng passed through the fortifications on the periphery of the infantry barracks, passed by the internal two-story small building of the officers and soldiers' dormitory building, and came to the most central core area of the infantry barracks.

The central core was different from the commander's residence or fortress that Hong Tiancheng imagined, just a ring of tall walled playgrounds that could not be seen as far as the eye could see.

This playground has four gates, south, south, and northwest, which just communicate with the city gate outside the entire infantry barracks.

"This ...... Is it where soldiers are summoned? Hong Tiancheng and his entourage soldiers stood on the review platform at the edge of the playground, looking at the blood-colored skull marks on the large playground that was empty and could accommodate thousands of people standing side by side at the same time, and asked the all-out war system in their hearts.

[Yes, host, this is the place to summon the corps of the system, as long as the central skull mark is not destroyed, and there is no indigenous inhabitant of the world entering the infantry barracks, you can summon soldiers, and the corps will be embodied in the playground in a formed situation, one regiment after another, and without the host's order, the summoned corps will go to the barracks outside the playground wall on their own under the leadership of the officer. 】

Hong Tiancheng's eyes narrowed slightly, and the all-out war system in his mind chose to consume two points of national prestige in exchange for a division of Taiping Army line infantry.

After the all-out war system was upgraded, although the price of soldiers was further reduced, and the bayonet of the card type also became mature in real modern infantry tactics, it lost the ability of Hong Tiancheng to summon troops by his side anytime and anywhere.

Now Hong Tiancheng must come to the barracks or administrative hall and other buildings, and then choose to exchange for recruitment, in other places, Hong Tiancheng can not be called by the army, of course, in the future, any capital-level historical city occupied by the Taiping Heavenly Kingdom can establish a set of system buildings to summon the army, as far as possible to avoid the situation that the army is too far away from the front line.

Of course, this kind of system building unified summoning also has an advantage, Hong Tiancheng only needs to prepare enough supplies in the nearby city of Kyiv, and after the corps that came out of the barracks to receive the supplies, he can directly embark on the journey, instead of being like a group of rogues, and he has to 'do it himself'.

And most importantly, with these system buildings, Hongtian has a military-industrial base for the mass production of ammunition.

In addition to the barracks and defense facilities, there is also an ammunition production workshop in the infantry barracks, as long as there are sufficient raw materials, black powder and lead bullets can be produced, and the workers in it are absolutely loyal Han civilians gifted by the total war system, and the complete secrecy of the military industrial system can be achieved!

It can be said that after owning this systematic construction area, Hong Tiancheng no longer needs to rely on white workers for the production of weapons and equipment, and naturally he does not have to worry about weapons technology flowing outside.

This may not be obvious now, but when the weapons of Hong Tiancheng's all-out war system are upgraded more and more, this kind of secret production base of all his own people has become very important.

The Taiping Army line infantry stood in a parade formation, and after giving a standard Taiping Army military salute to Hong Tiancheng on the review stand, there was an orderly formation out of the playground from the four gates, and then, a regiment of Taiping Army line infantry suddenly appeared on the playground again, one by one like robots, meticulously doing their own things.

Under this kind of efficient military discipline, Hong Tiancheng quickly spent 8 points of national prestige to exchange for four fully formed infantry divisions of the Taiping Army, with a total of 52,640 people!

And it is the kind of troops that have a complete range of personnel, from officers to logistics civilians, and can be pulled out and brought dry rations to the battlefield.

The ammunition base they carried was enough to cope with a high-intensity battle, and there was a slight surplus, so Hong Tiancheng only needed to provide them with enough food.

That's a huge savings!

Moreover, the Han workers in the firearms and ammunition workshop in the infantry barracks have begun to mass-produce ammunition, which is not high-tech, but has already taken the prototype of the advanced production concept of the assembly line.

In the future, with the upgrading of the infantry barracks, the production scale of the firearms and ammunition workshops here will also expand, of course, these system workers are given at one time, if the infantry barracks are breached, the system workers are killed, and the total war system will not be replenished......

Breaking the summoning function of the system building requires destroying the blood-colored skeleton mark in the central summoning playground, and if the attacking enemy does not realize this, Hong Tiancheng can continue to use the function of this system building after regaining it.

There is only one chance for the free gift of the system building to a capital-level historical city, once it is destroyed, Hong Tiancheng needs to spend the country's prestige to re-exchange, and the price is definitely unaffordable for Hong Tiancheng now.

The same principle is the same for the all-round artillery training camp and the administrative hall, except that the administrative hall occupies the smallest area, and after Hong Tiancheng exchanged two thousand administrative officials there, he no longer cares.

The exchange playground in the Almighty Artillery Training Camp is very small and can only accommodate hundreds of people standing in a queue at the same time, but the artillery workshop in the Almighty Artillery Training Camp covers a large area, and the system workers inside can produce their own shells through the study of ordinary shell samples in this world, as long as there are enough raw materials.

The biggest function of the infantry barracks and the all-round artillery training camp is that in addition to summoning the army out of nothing, it can become a military ammunition production base.

Of course, Hong Tiancheng can also order the system workers in the all-round artillery training camp to imitate the backward old artillery of this era, but the time taken to produce these old artillery is not much different from that of the indigenous artillery foundries in this world, and it needs to consume a lot of iron, and the performance of the artillery produced is as bad as the artillery captured by Hong Tiancheng, and there is no professional artillery operation, and the cost performance is too low.

In this era of limited transportation capacity, it is better to transport more ammunition raw materials to produce enough lead bullets and black powder to support the war of the army.

As for the siege artillery, the few bulky guys captured by Hong Tiancheng were enough to deal with it.

The sound of artillery in the 17th century was certainly terrifying, but it was muskets and cold weapons that really killed and injured the enemy.

Now there are still more than a hundred years before the invention of the flowering bullet and put it into the battlefield, even the range of the solid iron pellet is not satisfactory, the range of the grape bullet of the light field artillery is not as good as the musket, and the lethality of the artillery is the degree of hehe.
