I do research in ancient times

What Ning Fei wants to do is soil cement.

Niubei Mountain stretches for hundreds of miles, and some steep peaks are the natural barriers of Mozongwu Fort.

But the mountain is a barren mountain. Most of the mountain is exposed sand and rocks. A small number of shrubs that can grow green plants and are resistant to cold and drought are not edible.

It is said that people rely on mountains to eat mountains, and naturally no one wants to come if there is no food on the mountains.Wudai Jizi saw that Niubei Mountain was an unowned wasteland that no one cared about, and there were no products on the mountain worth fighting for, so he led his disciples to take root at the foot of the mountain.

After so many years, Niubei Mountain has lived up to expectations. The forest coverage rate has always remained below 5%. Occasionally, when the weather is good, a little grass grows, that is, it is completely bald and becomes the Mediterranean Sea. The difference is not much.

Hu Qi came over a few times and then gave up. Cattle and sheep would starve to death if they entered the mountain without gnawing on rocks. Not to mention there are a group of business people who are good at using institutions at the foot of the mountain. It is not worthwhile to exchange the life of a warrior for a barren mountain.

But Niubei Mountain is not useless.

After Chang Shan, the son of the sixth generation, succeeded to the throne, coal mines and saltpeter were discovered on the mountain, which is why he insisted on developing "Tianhuo Lei" despite all opinions.

Now that Ning Fei has a product map in his hand, in his eyes, Niubei Mountain is a treasure mountain!

Look, coal, saltpeter, iron, limestone, phosphorus... what do the experimenters like best?Of course, it is the experimental materials with complete categories, sufficient quantity and ready to pick up!

Now Ning Fei can suddenly understand the mood of Sixth Generation Gou!

With drawings and materials, who can resist doing it?

He wasn't interested in black powder, though.It's risky to make that thing, and Mo Zong won't be able to use it for the time being, the cost performance is not high, Ning Fei doesn't like it.

On the contrary, it is cement, which is easy to prepare and super practical, and can quickly solve Mozong's current housing dilemma.

Of course, what he wants to do is not the composite cement produced by modern large-scale industries, but the slag soil cement under the simple processing technology.

The natural rock whose main component is calcium carbonate is calcined at high temperature, decomposed quicklime and ground in advance, then mixed with gypsum and clay, stirred evenly and then crushed and calcined. Soil cement is done.

The grade of cement produced in this way is definitely not as high as modern standard cement, but it is enough to build houses and walls.

He knew about the mines on Niubei Mountain. Mo Zong's blast furnace and fire pit were ready-made. What's more, he prepared his own blueprints for preparing soil and cement, so he didn't need to exchange them from the system, which saved a lot of trouble.

He felt that this project was very reliable, but Mr. Yu was completely confused.

Fortunately, Mo Zong was used to obeying Juzi, so Mr. Yu didn't ask any more questions. He silently wrote down Ning Fei's words, and then reported on his current work before joining the harvesting army with Juzi.

The food aroused everyone's fighting spirit. Except for the guards on duty, the whole Wubao, regardless of gender, age, and age, all participated in the intense harvesting work.In order not to waste time, the people in the food room took their lunch directly to the field, and distributed a large boiled potato to each person, and worked while eating, which made everyone feel happy.

As a result, the potato field, which was expected to take another day to be dug, was emptied shortly after nightfall. Seeing the full warehouse of grain, everyone's eyes were full of satisfaction, and they felt that life had never been so full of hope.

After dinner, Ning Fei had a small meeting in the dining room.

No way, who made Shijian the only place in the city with a stool.

There is room in the main building, and there is a wooden statue of Yue Wanfeng, the son of the first generation, in the main hall, which is solemn and solemn.

However, in the meeting there, you have to pay homage to the patriarch first, and you have to suppress your voice so as not to disturb you, which is really restrained.

Ning Fei is from a technical background, he doesn't like meaningless red tape, and he hates people delaying the progress of the project the most.Ever since he knew the black history of this senior's negligence, he felt that Yue Wanfeng had to bear a lot of responsibility for Mo Zong to get into this situation.

Yue Wanfeng used the resources given by the system to climb to the pinnacle of life, but perfunctorily evaded his own obligations, wasting a lot of time and resources chasing personal fame and fortune, causing the system to run out of energy, Mo Zong was miserable and poor, and even his successor was also impoverished. Had to fight back.

He wanted to fight now when he saw the wooden statue. If he really had a meeting in the main hall, he might not be able to contain his emotions at any time, and it wouldn't be nice to speak rudely to the "Patriarch".

In addition to the three elders, Old Man Liu and Granny Qiu were also present at the meeting.They were specially invited by Ning Fei to arrange the planting and harvesting of cotton.

It was the first time for the two old people to have a meeting with Xin Juzi. They were very cautious at first, and they didn't know where to put their hands and feet.

Ning Fei saw the nervousness of the two of them, so he smiled and chatted with them about harvesting potatoes today. Harvest is the most popular topic among Mozong, and the atmosphere in the dining room was quickly eased.

"That's such a baby!"

Old man Liu said excitedly.

"The three granaries can't hold it! Even if our wheat is not harvested, it will be enough for this winter! Old man, I have lived for so long, and I have never seen so much grain!"

"Juzi! You said that one bean can grow several sprouts, but is that true?"

Hearing his question, Ning Fei nodded.

"Of course it's true."

"So it is necessary to leave a part for sprouting, and the preservation of potatoes in winter is also very important."

"Today I went to the granary to have a look. I feel that the house is a bit dilapidated and not cold and moisture-proof enough. Once it snows, the potatoes are easy to freeze and rot."

"Potatoes cannot be used for breeding if they are blocked."

Hearing what he said, all five people present became anxious.Old man Liu even stood up directly from the bench, and asked anxiously:

"Ah! What should I do then?"

In just two days, potatoes have become his favorite, no less than his grandson Liu Tie.Now that I heard that these treasures may not be kept, the old man's heart trembled with pain.

Ning Fei paused, "It's nothing, I think we should rebuild a granary."

"The three granaries now are very small, and rat holes have already been drilled in them. Why don't we build another big one."

As soon as these words came out, he found that everyone present was a little embarrassed.

Mozong's granary was built in different years, the reason why the volume is not large is because Mozong's grain has never been abundant, and it is empty when it is built, which is a waste of materials.

Who would have thought that when they met Xin Juzi this year and led everyone to find potatoes, these granaries would appear out of date.

"That's fine," the old Yu who was in charge of the construction said immediately, "I will arrange people to go out to pull stones and burn bricks when I get back, and try to build a big one before winter."

"Alright."

Ning Fei nodded.

"It just so happens that I also have something I want to study. You assign a team to me. If you have good physical strength, you can dig mines and burn kilns."

As soon as they heard that Jizi wanted to start work, the expressions of the three elders froze instantly.

There is no other reason, the previous lesson was too tragic, Juzi Changshan deliberately turned on the sky fire thunder, and as a result, not only died in the mountain, but also almost all the elites of the sect were destroyed, and Mo Zong almost wiped out.

"May I ask you, what do you want to build?"

Xie Lao asked cautiously.

"Ah, nothing."

Ning Fei didn't understand why they were nervous, "It's earth cement, which is used to bond the joints of bricks. It can also be applied to the outer city wall to strengthen the wall and prevent moisture and erosion."

Hearing what he said, everyone in the dining room breathed a sigh of relief.

"Oh, it's mortar."

Yu Lao, who was in charge of the construction, nodded.

"That jig can be studied at ease, and there is no need to rush to catch up with the progress. It doesn't matter if it can't be built before the warehouse is built. Our civil engineering team can use it if it is completed."

"The outer wall of Wubao was built by ourselves, and it was glued and painted with Zongmen's special mortar. Although it is not as magical as Juzi said, it has been used for decades without any major problems."

He said it very easily, obviously he didn't believe that Ning Fei could really research anything.

Ning Fei took out the potatoes that saved Mo Zong from danger, for which everyone is grateful to him.But gratitude is gratitude. I found that potatoes cannot prove Ning Fei's research and development capabilities. Not to mention Yushan and Mu Donglai, even Mr. Xie, who supports Ning Fei, knows this well.

Mo Zong established his sect with skills, and those who are capable and capable speak harder than others.But Ning Fei is already a juzi, and juzi's requirements must always be met.The three elders discussed together for a while, and finally selected a few young people from the civil engineering group and the smelting group to be included in the list, among them was Liu Tie, whom Ning Fei had dealt with before.

Ning Fei has no objection to this, and doesn't care about everyone's attitude.

It is normal to be questioned when a project is established, and he has experienced a lot when he entered the group before.

Lu Yao knows horsepower, and he can see people's hearts after a long time. It will be fine when there are results.
