Iron is relatively easy for Ren Baqian, as long as he builds a blast furnace and forges with water power, even if he uses a rope to pull up a heavy hammer to forge it, it is more efficient than repeatedly hitting it with a hammer.
As long as there is enough steel, each soldier can also be equipped with a heart shield. The ancient warriors have strong vitality, and having a heart shield can reduce many casualties without affecting their actions.
However, regarding the issue of food, Ren Baqian was a little scratching his head.
New crops such as pumpkins, potatoes, and sweet potatoes have just been promoted, and it will take at least half a year before there will be a considerable amount of harvest. Only then will these crops be available to the civilian population, reducing the meat consumption of the civilian population and replenishing the army.
There is a problem here that he has never been aware of before, that is, for the ancient warriors, especially fighting on the battlefield, they must eat a lot of meat to ensure sufficient physical strength. Because the strength of warriors comes from food, and the animal meat in this world contains the most substances that can be converted into the required heat.
No matter how many pumpkins and potatoes there are, it is impossible to use them as staple food, let alone as the staple food of the army.
If you only eat sweet potatoes and pumpkins, you don’t have to do anything else in the day. You eat breakfast and lunch, lunch and lunch, lunch and dinner, and dinner and supper.
Ren Baqian died bitterly for a long time. In this case, there was only one way to replenish the army's food, and that was fishing.
The ancient people ate less fish. On the one hand, the ancient people were used to hunting and animal husbandry, and had no habit of fishing. On the other hand, it was troublesome to eat because of the thorns.
Moreover, unlike livestock, fish can be sent somewhere alive, and in Dayao's weather, it only takes one day for them to stink.
Therefore, unless it is along the river and there is a lack of other food, fish is generally not on Dayaoren's table menu.
Ren Baqian has an idea. The two points that the ancient people don't like fish can actually be solved with only one method—canned fish, similar to canned sardines. After being processed at high temperature, even the thorns are so crispy that they can be chewed and eaten together.
This is a feasible way.
There are two options, one is glass jars, which are easy to achieve, and glass factories are readily available. After being packed in a glass bottle, it is heated at high temperature, stuffed with a cork, and then sealed with wax. Although the shelf life is not as long as that of vacuum cans, it is enough.
The disadvantage is that the transportation is more troublesome, the glass bottle is too heavy, and the cans need to be wrapped with straw layer by layer when packing, otherwise, with the road of Dayao, only glass slag will be delivered to the place.
The other one is tinplate cans, that is, tin-plated iron cans, but he doesn't know if Dayao has tin mines.
What's more, making tinplate cans is not only about having iron and tin, but also requires many other processes.
Seeing his frown, the empress asked, and Ren Baqian told her about the idea of making canned fish.
After hearing this, the Empress wrinkled her nostrils slightly, and seemed a little happy: "This is a good idea. Glass cans are fine, and you can make them bigger. I always think that the cans on your earth are too small to be eaten in one bite."
Ren Baqian clapped his hands: "Yes, it can be made into a glass barrel, a glass jar, and made thicker, so that it will be much easier to make and transport. Your Majesty is really talented, and he thought of such a good idea all at once. The solution, I never thought of it."
The empress "hummed" twice in her nose very usefully, her small face was slightly raised.
Ren Baqian felt that the empress was getting cuter and cuter, and he was always eager to kiss her.
However, he had to go back to Earth at night. In order to prevent serious injuries and go back, Ren Baqian still gave up this tempting idea.
"My intuition tells me that you seemed to be thinking of some bad idea just now?" The empress squinted at him.
"Your Majesty... wronged!"
That night, Ren Baqian returned to Earth, recruited assistants, found someone to prepare exam papers, and at the same time searched the Internet for ancient forging machine blueprints.
The learning progress of these ancient students, the literacy level is about the fourth grade of elementary school, mathematics is the second grade of elementary school, physics and chemistry are outstanding courses, and the progress is inconsistent, so it is no need to think about taking some papers at school , You must find someone to come up with a set of test questions.
When the news of Ren Baqian looking for an assistant was noticed by the state, there was another round of intensive analysis. After analyzing gender, age, appearance, height, and personality, an additional assistant appeared beside Ren Baqian a few days later.
Judging from the Adam's apple and the sex on the information, it should be a woman, her voice and walking are a bit like a man, her appearance is more masculine, and she has a flat chest.
This is the most appropriate result after many people's back and forth analysis.
When Ren Baqian saw this candidate, he didn't know what to say. Although the one in front of him was either not very beautiful, or he was seven feet tall, although he nodded in his heart, he had to reluctantly give up.
But this person really exceeded his requirements, right
And there is also a man's name, Shen Feng.
But regardless of this person's gender, other aspects are quite in line with Ren Baqian's requirements.
After Ren Baqian, everything can be changed
After a little thought, he hired this person with test papers and street lighting equipment.
In the past two days, he hesitated between bringing street light equipment or salt, and bringing 600 catties of salt at a time was a drop in the bucket for Dayao.
To ensure that more than 30 million people use salt, the salt consumed in a month needs to be about 2 million catties. This is still based on the current situation that the salt intake of Dayao people can only reach half of the average person on the earth.
If you want to achieve normal salt intake, you need at least 4 million catties.
It doesn't make much sense to go back to Earth once a month after each five-day class, and the maximum weight is only 2600 catties.
Let's fix the street lights in the palace first.
Salt has only seen it for a few days and went to see the black water pool by himself. If it doesn't work there, you can only go to Yunguo to grab it.
…
After the first day of the palace meeting, Dayao discussed for several days, and the matter of attacking Yun Kingdom was almost settled.
As for Daxia, no one thought about it, anyway, it was the soldiers who came to cover the water and earth.
And Gu Zicheng, contrary to everyone's expectations, was not sacrificed to heaven, but thrown into prison. Everyone in the entire embassy was thrown into prison, and only one person was driven back to Daxia with a letter of credence.
But everyone knew that the day when Daxia attacked was the day when Gu Zicheng was sacrificed to heaven.
His legend that has lived for so many years has come to an end.
On the fourth day of everyone's discussion, news came from Pingcheng that Dayao had increased his troops by 200,000 in Tiesuoguan, Qingyangguan, and Yunluocheng three days ago, and they were ready to move.
On the same day when the empress received the question from Emperor Daxia, Daxia's reinforcements had already arrived, and they arrived at night.
In the past few days, the Northern Protectorate's Mansion discovered that there was more cooking smoke in these three cities than before, and they only noticed it from a high altitude by using the drone left behind by Ren Baqian.
Daxia's increase in troops was faster than everyone expected. This also shows that Emperor Daxia, as Ren Baqian said, was just looking for an excuse to become famous, and he didn't care how the empress explained it. It must be done.
But correspondingly, Dayao didn't even think about explaining.
