Cement?

Hearing this, many of the guards had their pupils constricted, their eyes dilated, and their faces looked surprised.

"Cement?"

"Why haven't you heard of it?"

"When I look at this name, it seems to be like water but not water, like mud but not mud."

Seeing the expressions on everyone's faces, Boss Qin smiled mysteriously and said, "Everyone, come with me." ”

Seeing that things seemed to be turning around, the guards were overjoyed and hurried to follow.

Boss Qin led him to a clearing, but this clearing, the whole body was gray-white, hard and dry.

It is clearly different from the moist land that is overgrown with weeds around it.

In the open space is a pile of gray-white powder mixed with water, which forms a peculiar solid-liquid state when exposed to water.

Like mud but not mud, like sand but not sand.

"Look, this is cement!" Boss Qin pointed to the pile of powder that was being stirred with water and said.

When the guards heard this, they all frowned.

They were overjoyed when they thought cement would be a harder building material than red brick.

Who would have thought that it would be such a soft thing, what use could it be?

This person seems to be honest, isn't he making fun of us?

Seeing the expressions of these guards, Boss Qin was not only annoyed, but looked like he was holding a pearl of wisdom.

"What do you think of the difference between the ground under your feet?"

Hearing this, the guards stomped their feet one after another, but found that the gray-white ground under their feet was particularly hard, and even if they used internal force, they could only leave a few inconspicuous traces on it.

When everyone saw this, they were shocked: "What is this?" ”

"If it is used to build a city wall, even if it can't stop the catapult, I am afraid it can have a miraculous effect!"

Seeing that the expressions on everyone's faces gradually turned from disappointment to shock, the corners of Boss Qin's mouth rose slightly, and he said, "This is also cement." ”

Rumble!

As soon as these words came out, it was like a thunderbolt on a sunny day, and the guards were stunned in place, at a loss.

"This little brother, don't be joking."

"You said clearly earlier that the soft thing is cement, and the ground is so hard, how can it be cement?"

"As you don't know, cement starts out as a powder and dissolves in water. At this point, it is in a liquid state, so it can be applied anywhere, and when it solidifies, it will be extremely hard! ”

"If you use it with red bricks, the effect is even better!"

Hearing this, the guards became short of breath.

It can be applied anywhere, and when it solidifies, it becomes even harder!

This... Isn't this a weapon for repairing the walls?

There is such a thing in the world!

Master Xiang also saw the role of cement, and stepped forward and asked: "I don't know if Huainan can use this cement and red brick to build a house now, if there is, I will also go and have a look, so that I can have a long insight." ”

Hearing this, Boss Qin nodded, and said, "Although this cement and red brick were first used in Jiangnan County, we also have them in Huainan. ”

"You know the center of the city, the most luxurious area, there are a bunch of houses, all brick houses built of red brick and cement, and the owner has given a loud name, what is it... Huainan Yipin. ”

"Huainan Yipin..."Master Xiang muttered in his mouth, showing an interested look, and said: "It's a good name, if you have the opportunity, you will definitely buy a set and experience it, what is the difference between living in this brick house." ”

"Eh, this house is not for sale."

"Not for sale?" Master Xiang showed surprise: "The house is built and not sold, isn't this a loss-making business?" ”

"Well, you don't know it. The best location in Huainan is made of the best materials, or brick houses, and there are not many such mansions that the whole Huainan can afford. ”

"So we don't sell it, we just rent it. Rent to travelers like you who come from other places and don't have a bad budget. ”

When Master Xiang heard this, he nodded, showed appreciation, and said, "It's a good idea." ”

"Brothers, when you go to Huainan City, you will definitely go to this Huainan to experience a good life."

The guards nodded their heads, wondering how sturdy the brick house could be.

At this point, the brick kiln department is finished.

The only ones left are the Ministry of Agriculture and the Ministry of Smithing.

Master Xiang first looked at the Ministry of Agriculture, it was still spring, and the farmers in the rice fields were facing the loess with their backs to the sky, and they were planting seedlings.

However, unlike before, they were all red and full of energy between their eyebrows.

Because of the planting of these seeds, the grain yield in the autumn may be increased several times.

"It is said that the hybrid rice researched by Gu Shijun can yield 400 kilograms per mu a year?" This is the issue that Master Xiang is most concerned about.

Since ancient times, marching and fighting, the issue of grain and grass has been the top priority.

What's more, in the Northern Expedition, the battle line has to cross the Yayu Mountains, and the grain and grass are even more important.

Sufficient grain and grass will be the confidence of Daqian to defeat the Northern Yan and recover the territory.

It's a pity that Li Lao Er didn't give him a positive reply, but shook his head.

Seeing this, Master Xiang chuckled in his heart.

However, he knows that it is normal for most grain merchants to like to brag about their seeds.

But even if there is no annual output of 400 kilograms, 350 kilograms, or rather, 300 kilograms is always available, right?

"You're just talking about the first generation of seeds, and now after our research, the second generation of seeds has been born."

"That's enough to produce 500 kilograms per mu per year."

Rumble!

As soon as these words came out, it was like a thunderbolt from the sky, making everyone present stunned on the spot and unable to let go.

After a long time, Master Xiang came to his senses.

grabbed Li Laoer's hand violently, and asked eagerly, "What you said is true?" ”

"Naturally, there will be a slight deviation, but on average, the value should be about 500 kilograms per mu."

Five hundred kilograms! Five hundred kilograms!

The four big words have been echoing in Master Xiang's mind, you know, this is a thousand catties of grain!

Nowadays, even in such a fertile land as the Jianghuai area, except for hybrid rice, the annual yield of the rest of the rice is only one or two hundred kilograms per mu, which is more than one and a half kilograms compared with 500 kilograms.

If all the territories of Daqian can be planted with this seed called hybrid rice, then why worry about the lack of food in the Northern Expedition?

When the time comes, the sergeants will eat as much as they want every day!

Wouldn't it be better to take Beiyan than to take things?

From this point of view, this hybrid rice is the most important weapon of the country, and it needs to be put into practice as soon as possible.

At least before the Northern Expedition, plant the Jianghuai area!

Seeing that Master Xiang showed such a look, Boss Qin secretly said in his heart that it was not good.

Is this kind of child so likable? If it goes on like this, I'm afraid this business is going to be snatched away by the second child of the Li family!

Thinking of this, Boss Qin couldn't hold back any longer, stepped forward, and said, "Honorable guest, their Ministry of Agriculture only has one hybrid rice. In contrast, our brick kiln department has both cement and red bricks, no matter how you look at it, we are superior. ”
