Chapter 308

Iron is relatively easy to solve for Ren 8000. As long as a blast furnace is built and hydraulic forging is used, even if it is forged with a heavy hammer pulled by a rope and cable manually, it is more efficient than beating repeatedly with a hammer.

As long as the steel is enough, each soldier can be equipped with a safety goggle. Ancient soldiers have strong vitality. Having a safety goggle can reduce many casualties without affecting their actions.

However, Ren 8000 is scratching his head about the problem of food.

New crops such as pumpkin, potato and sweet potato have just been popularized, and it will take at least half a year to harvest a considerable amount. Only then can these crops be targeted at civilians, reduce folk meat consumption and supplement them to the army.

There is a problem that he has not been aware of before, that is, for ancient warriors, especially in battlefield fighting, they must eat a lot of meat to ensure sufficient physical strength. Because the power of martial arts comes from food, and animal meat in the world contains the most substances that can be converted into needed calories.

No matter how many pumpkins and potatoes there are, they can't be used as staple food, especially for the army.

If you only eat sweet potatoes and pumpkins, you don't have to do anything else in the day. You have breakfast, lunch, lunch, afternoon dinner, dinner and supper.

In this case, there is only one way to supplement the army's food, that is, fishing.

The ancient people ate less fish. On the one hand, the ancient people were used to hunting and animal husbandry and had no fishing habit. On the other hand, it was troublesome to eat because of thorns.

And unlike livestock, fish can be sent to a place alive. In bright weather, it will stink in one day.

Therefore, fish are generally not on the table menu of Dayao people unless they are along the river and lack other food.

There is an idea that eight thousand of the ancient people love fish. In fact, they can solve them in one way. They can be sardine canned fish, and can be eaten together after being cooked at high temperature.

This is a feasible way.

There are two choices. One is glass cans, which is easy to achieve. Glass factories are ready-made. After the glass bottle is packed, heat it at high temperature, plug it in, and then seal it with wax. Although the shelf life is not as long as vacuum cans, it is enough.

The disadvantage is that the transportation is troublesome, the glass bottles are too heavy, and the cans need to be wrapped layer by layer when they are packed. Otherwise, the glass slag can only be sent to the place by Dayao road.

Another is tinplate cans, that is, tinned iron cans, but he doesn't know whether Dayao has tin ore or not.

Besides, making tinplate cans requires not only iron and tin, but also many other processes.

The female emperor saw him frown and asked. Ren 8000 told her the idea of making a fish can.

After hearing this, the female emperor wrinkled her nose slightly and seemed a little happy: "this is a good way. Glass cans can be made bigger. I always thought that your earth cans are too small to eat in one bite."

Ren Bayi clapped his hand: "yes, it can be made into Glass barrels and glass jars. It's much easier to make and transport. Your majesty is really gifted. He thought of such a good solution at once, but I didn't think of it."

The female emperor was very useful. She "hummed" twice in her nose and raised her little face slightly.

Ren 8000 felt that the female emperor was becoming more and more lovely, which made him always ready to kiss.

However, he had to go back to earth at night. In order to prevent serious injury, Ren 8000 still gave up this tempting idea.

"My intuition tells me that you seemed to have a bad idea just now?" The empress looked at him sideways.

"Your Majesty... Wronged!"

That night, Ren 8000 returned to the earth to recruit assistants, find someone to prepare the examination paper, and find the ancient forging press drawings on the Internet.

The learning progress and literacy level of these ancient students are probably in the fourth grade of primary school. Mathematics is the second grade of primary school. Physics and chemistry are outstanding courses, and the progress is different. If you want to take some papers at school, you don't have to think about it. You must find someone to work out a set of test questions.

When the news that Ren 8000 was looking for an assistant was noticed by the state, it was a burst of close analysis. After the analysis in terms of gender, age, appearance, height and personality, Ren 8000 had an assistant around him a few days later.

Look at the sex on the Adam's apple and data. It should be a woman. She speaks and walks a little like a man. She looks masculine and has a flat chest.

This is the most appropriate result after many people's analysis.

When Ren 8000 saw the candidate, he didn't know what to say. Although the one in front was either too beautiful or seven feet * *, although he nodded in his heart, he had to give up.

But this man is really beyond his requirements, isn't he?

And there is a man's name, Shen Feng.

However, leaving aside the gender of this man, other aspects meet Ren 8000's requirements very well.

After Ren 8000, everything can be changed

After a little thought, he hired this man with test papers and street light equipment.

These two days, he hesitated about whether to bring street lamp equipment or salt. Bringing 600 kg of salt at a time is a drop in the bucket for Dayao.

To ensure that more than 30 million people use salt, the salt consumed a month needs about 2 million kg, which is still under the condition that the salt intake of Dayao people can only reach half of the ordinary people on earth.

If you want to reach the normal salt intake level, you need at least 4 million kg.

It doesn't make much sense to go back to earth once a month after five days of classes.

I'd better finish the road lights in the Palace first.

I've seen salt for a few days. I went to see the black pool myself. If it doesn't work there, you can only rob it in cloud country.

……

After the first day of the temple discussion, Dayao discussed for several days, and the attack on the cloud state was almost decided.

As for the summer, no one thought about it. Anyway, the soldiers came to block the water and cover the earth.

Gu Zicheng, to everyone's surprise, was not sacrificed to heaven, but put into prison. Everyone in the whole embassy was put into prison, and only one was driven back to Daxia with a letter of state.

However, everyone knows that the day of the summer attack is when Gu Zicheng is sacrificed to heaven.

His legend, which has lived for so many years, has come to an end.

On the fourth day of discussion, news came from Pingcheng. Three days ago, Dayao increased his troops by 200000 in Tiesuo pass, Qingyang pass and Yunluo City, and was ready to move.

On the same day that the female emperor received the emperor's question, the summer surge had arrived, and it arrived at night.

In recent days, the northern guards found that there was more cooking smoke in these three cities than in the past. They only detected it from high altitude by using the UAV left by Ren 8000.

The increase of troops in Daxia was faster than everyone expected, which also shows that the emperor of Daxia, as Ren 8000 said, was just looking for an excuse to become famous. He didn't care how the female emperor explained. War is imperative.

But correspondingly, Dayao didn't want to explain at all.
