With enough workforce, the pace of house construction is unusually fast.

More than 10,000 people working at the same time is a challenge for Shi Caiying.

The number of people is naturally enough, so how to give full play to the labor force of these people is the key.

And Qi Heng handed over all these things to Shi Caiying and his officials.

At the same time, it can also exercise the ability of these people.

While all the labor force in the city was devoted to construction, 500 soldiers were separated from each other.

These 500 people are the elite of all the officers and men in the army.

Among them, 100 orphan soldiers with special family backgrounds and no surviving family members were handed over to Zheng Guangzu and set up a simple intelligence agency, which was regarded as a job behind enemy lines, called the secret guard.

Among them, it can be divided into martial guards and shadow guards.

Wu Wei is responsible for killing the enemy, and Ying Wei is a full-time intelligence.

The other four hundred people were handed over to Mu Ying.

Although Mu Ying is still young, even younger than him Qi Heng, Mu Ying knows better than him how to live and deal with things in this world.

After all, he was an orphan at a very young age, and his experience was not comparable to Qi Heng.

At the same time, it can be regarded as the first challenge for Mu Ying.

And their existence, Qi Heng called it: Divine Barracks.

The number of people will not be too much, and the role is modeled on the special forces of later generations.

The most advanced and sophisticated weapons will be equipped with them.

Perform special missions that are different from frontal combat in the field.

Perform special tasks such as decapitation, food burning, etc., alone or in conjunction with the Secret Guard.

However, the role of the Divine Battalion is different from the existence of the Divine Guards in the Dark Guard, which specializes in the battlefield and the Martial Guards are mostly behind enemy lines.

The Divine Barracks is an army order.

When they first heard Qi Heng's decision, both Mu Ying and Zheng Guangzu were in a state of confusion.

However, after hearing Qi Heng explain the role of these two institutions in detail, he understood Qi Heng's intentions.

At the same time, Qi Heng also made corresponding training programs for these two institutions.

For example, everyone in the Divine Battalion needs to be good at riding skills, rock climbing and other special terrain to travel ability.

The Dark Guard, on the other hand, needs to learn the dialects of various places, the skills of each class, and strengthen the ability to memorize and assassinate.

After explaining the big aspects, Qi Heng handed over all the next things to them to study and study by themselves.

Now that there are full-time subordinates in charge of all aspects of the city, Qi Heng himself is idle.

In recent days, he has been helping Shen Wansan improve his efficiency.

At the same time, the research and development of cement and the construction of cement plants were also started.

According to Qi Heng's assumption, the role of concrete is still very large and wide.

If it can be really mass-produced, it will be of great help to them.

It's not just city defense.

There are also other aspects such as transportation and water conservancy, and the emergence of concrete can bring about transformative improvements in these aspects.

If you want concrete to be mass-produced, other materials are better said, and the key is the refining of cement.

According to the modern cement classification of later generations, except for special buildings, ordinary cement is basically used on weekdays.

This kind of cement can basically meet the current needs of Qiheng.

The composition of ordinary cement can be divided into limestone, clay, iron ore powder.

It is made of limestone, clay, iron ore powder in proportion to grind and mix, at this time the mixture is called raw meal.

Then it is calcined, and the product after calcination is called clinker.

In the modern production process, gypsum is basically added at this time, and the main function is to adjust the setting time of cement.

But today's conditions are naturally not comparable to today, although gypsum can also be made, but whether it is to save time or cost, when these cements are only used in some simple construction processes, this step can be reduced.

The clinker is simply mashed to produce the required cement.

With cement, combined with other materials of concrete, mixing according to a certain proportion, concrete can be formed.

The process is actually quite simple.

The difficulty lies in the availability and efficiency of raw materials.

For example, cement, the limestone in the cement composition is not difficult to find, and it can be obtained by digging two mountains at will.

Clay and iron ore powder are not a difficult task.

But the question is how to dig the limestone and how to grind the stone into powder after the excavation.

Of course, there are rough and simple ways.

Just smash and grind the flour directly by manpower.

But this efficiency is too low.

The manpower required is also too high.

Not to mention any major national defense projects such as the Great Wall, just one Huanggang City may consume the labor force of the people in the entire city.

So, the first thing to solve is the problem of tools.

This is also the reason why Qi Heng is personally responsible.

However, it is not impossible to do anything until the tool is developed.

Although it is winter, ore mining can still be carried out.

It is possible to reserve limestone in advance for the next thing.

At the request of Qi Heng, Shen Wansan had already begun to prepare.

Explosives are not an uncommon thing in this day and age, and it is not difficult to use the power of explosives to open mines and blast them.

In addition to these, the issue of Haozhou City is also being carried out at the same time.

Especially after forming a secret guard, Zheng Guangzu has been sent to Haozhou City by Qi Heng again, preparing for the next mission.

And there are letters from Haozhou City that want to exchange Guo Tianxu, which have come almost every day in the past few days.

Even the price code has been raised to the level of two thousand soldiers.

In this regard, Qi Heng's attitude is very clear, it is impossible to release Guo Tianxu before he completely brings Haozhou City under his command.

But in case the dog jumps off the wall in a hurry, he has always shown an ambiguous attitude, between letting people discuss the chips with Haozhou City.

It's also about buying some time for the Dark Guard.

Guo Tianxu was robbed just now, and now Haozhou City can be said to be heavily guarded.

It will have to be delayed for some time to achieve the desired effect.

In short, Qi Heng's "strategic policy" is to peacefully 'liberate' Haozhou City.

The backyard of the county government.

It's different from the deserted ones of the past.

Since Ma Xiuying took the lead and began to weave linen clothes for Qi Heng and them, this place has almost become Ma Xiuying's base.

Now, although the three thousand Mai have long been completed, they have also been deployed in the army.

But the number of soldiers has increased a lot now, and the linen clothes are far from enough.

Not only that, but also the people of the city.

Linen wasn't just needed by soldiers.

Therefore, Ma Xiuying and the sisters around her have not dispersed, and the number has even increased.

It's just that seeing that so many people come in and out of the marshal's mansion and the backyard of the mansion every day, Qi Heng is still quite worried about safety.
