In terms of life experience, in fact, Li Qinzai is not as good as ordinary dealers.

In this era of relying on the sky to eat, it is not easy for a farmer to grow up safely and smoothly.

Not only do they have to work hard to farm, but they also have to hunt, dig wild vegetables, collect and hoard all kinds of edible food, and be ready to deal with natural disasters.

Snow disasters, floods, droughts, locust plagues, and all kinds of disasters emerge one after another.

In this regard, Li Qinzai's experience is far inferior to that of Zhuang Hu, and his sense of crisis during the disaster year is far less than theirs.

Li Qinzai thought that giving food to the farmers in the disaster year was relief, but in fact, what the farmers wanted was not food, but that there was a way to live in addition to farming in the disaster year, even if there was no harvest in the field, they could still rely on their strength to earn food for their mother-in-law and children and feed the whole family.

This is not only self-esteem, but also a sense of anxiety about the future.

Every year of disaster, he stretched out his hand to the master's family to ask for relief, and over time, he really became a slave.

By selling labor to earn food, any generation can be an upright person, and when he goes out, he is still a man who stands up to the sky.

Li Qinzai understood the thoughts of the farmers and admired them deeply, so he no longer mentioned the word "relief".

After the county lord of Jinxiang came to Zhuangzi, he didn't seem to have any intention of leaving.

Every day with Cui Jie, the two women seem to have endless words, but Jin Xiang's attitude towards Li Qinzai is still polite and cold, obviously cheating her father out of money.

In fact, it is easy to ease the relationship with her, just return the deceived money.

But Lee didn't think about it at all.

Why should you pay back the money you got by being cheated by your ability? The relationship is stiff and cold, I don't plan to marry her, nor do I plan to sleep with her, does it matter if the relationship is good or bad?

Every day, in addition to teaching the students, they also inspect the ditch digging projects of the farmers.

This is a project that will be beneficial to future generations, and Lee takes it very seriously.

Digging a ditch is not digging a ditch, the process is not simple, after digging the ditch, it is necessary to keep ramming the earth, tamp the soil in the ditch, and then smear the wet mud, and then spread a layer of dry soil to continue tamping.

The construction site was in full swing, three or five men were bare-chested, and they lifted a thick log and smashed it to the ground, and the construction site was full of human-shaped pile drivers, all of which were small electric motors.

Li Qinzai squatted on the edge of the ditch, watching the farmers smear the ditch with wet mud, and his brows became more and more wrinkled.

"What's the principle? Smear on wet mud and then spread dry soil, isn't this taking off your pants and farting? ”

A farmer squatting next to him said with a smile: "Wu Shaolang is a rich and noble man, you don't understand, the wet mud is smeared and dried, and then the dry soil is paved and tamped, and finally a layer of wet mud is smeared to dry, so as to ensure that the ditch will not seep into the soil when the water passes, otherwise the water attracted will not wait for the ground, and it will all go into the soil." ”

The Zhuang family surnamed Wei who spoke was the son of the old Wei who was still conquering the remnants of the Baekje campaign.

Compared with Lao Wei's old and unserious, Xiao Wei ...... It doesn't look serious.

Other farmers are working hard to drive piles, but Xiao Wei is lazy to squat on the side and chat with him, this attitude has to deduct him at least two taels of grain.

"From Weishui to the head of our Zhuangzi, we have to connect several main canals, and according to this kind of rammed earth inch by inch, we will ram it to the year of the monkey and the month of the horse?" Lee was dissatisfied with the construction schedule.

Xiao Wei said in embarrassment: "But that's how you dig a ditch, otherwise what?" ”

Li Qinzai blurted out without thinking: "With cement, this won't be?" ”

Xiao Wei was stunned: "What is cement?" ”

Li Qinzai was also stunned.

Cement has not yet been launched, and the people of the Tang Dynasty have no idea what it does.

Then Li Qinzai's spirit perked up, yes, cement! This is a good thing, not only for digging ditches, but also for building roads, bridges, and military walls and fortresses......

If it is popularized, the value of cement is not inferior to gunpowder.

It is used for people's livelihood, and it is a necessary item for infrastructure madness, and it will become indestructible when used in any building.

For military use, gunpowder is offense, cement is defense. Both of them are necessary for the Tang Dynasty to attack cities and seize land in the future.

Li Qinzai squatted by the ditch and thought for a long time, then clapped his hands and stood up.

"The rammed earth procedure has stopped first, everyone go and do something else, and assign a hundred or so people to me, I can be useful."

After speaking, Li Qinzai went back to the other courtyard.

Sitting alone in the study, Li Qinzai held the pen and tried to think about the firing method of cement.

It's not too difficult, but it's not that easy either.

It is extracted from limestone at high temperatures, but it is not only limestone required for its formation, but also gypsum powder, iron slag, clay and other substances are mixed in the firing process.

Li Qinzai doesn't remember much, anyway, it was burning, burning, burning, burning, and burning, and this thing was burned out.

Licking the dog can't lick the love of the goddess without stopping, but the lime keeps burning but can burn the cement, what a heart-piercing nature.

As for how many degrees of high temperature are needed, it doesn't matter, let's talk about burning first.

Pick up the pen and write down the steps on the paper, and draw a few drawings of the kiln, before the ink is dry, fold the paper and put it in his arms, go out and say loudly: "Ah Si, call our family, and the villagers, ready to dig the kiln!" ”

Liu Asi, who came in a hurry, was stunned: "What kiln?" ”

"It's over digging," Li Qinzai took out the drawings from his arms and gave them to him, and said, "Dig according to this pattern, get more people, and the farmers in the neighboring villages will also call over, and I will pay the wages." ”

Liu Ah Si said: "Fifth Shaolang has come up with something new?" The blueprint villain will keep it for you, and send someone back to the Gongfu quickly, and never let outsiders steal the secret recipe. ”

"What do you want to keep, what is the secret recipe for digging a broken kiln? The kiln is dug out, and the discerning person can understand it at a glance, what is the use of the secret recipe? Hurry up and do it. ”

The kiln digging project is not small, and Li Qinzai has to dig more than just one or two kilns.

Because he didn't remember the specific method of firing cement in his previous life, Li Qinzai could only dig a few more kilns and try them in different ways.

Not only digging kilns, but also collecting limestone and clay from the nearby mountains, sending people to the Ministry of Industry of Chang'an to ask for iron slag, etc., all require a lot of manpower.

Liu Asi's execution is good, he knows that every time Li Qinzai hands him over the drawings, he will definitely create earth-shattering good things, from the divine arm bow to gunpowder, three-eyed guns, etc., which are extremely important to the Tang Dynasty and the British government.

Hurriedly went out with the drawings, and soon Liu Asi summoned the villagers, and at the same time sent people to the Chang'an Ministry of Industry to ask for iron slag and ask for labor from the neighboring village.

In less than a day, Ganjingzhuang has gathered hundreds of young and strong laborers.

According to the drawings, under the personal command of Li Qinzai, a halfway up the mountain away from Zhuangzi was selected and the kiln was dug up.

The ditch digging project was temporarily stopped, and Li Qinzai felt that if the cement was fired first and then the ditch was resumed, the effect would be much stronger than the stupid rammed earth of the villagers.

The farmers in the whole village don't know why, they don't know why Wu Shaolang suddenly ordered to dig the kiln, but the master has an idea, and the farmers naturally won't say anything, anyway, they are all working, what are they not doing.

For several days in a row, Li Qinzai almost stood on the construction site, staring at the farmers digging kilns.

Two days later, Cui Jie and Jin Xiang's two best friends finally felt as if something was missing in their lives, so they came to the construction site together.

Jin Xiang looked at the hot construction site and couldn't help but be slightly surprised: "Uncle Li is ...... What to do? ”

Cui Jie chuckled: "My husband is different from ordinary people, he always has some strange thoughts in his head, and sometimes he creates a new thing unconsciously, and it is very useful." ”

Jin Xiang said thoughtfully: "I have heard some things about your husband, who was absurd when he was young, but now he has become a genius of the Tang Dynasty and has created a lot of great good things, he ...... Is it all such a sudden thought? ”

Cui Jie snorted, staring at Li Qinzai's busy figure obsessively, and said softly: "He...... It's really different. ”

Jin Xiang noticed her obsessive gaze, and couldn't help but snort, and muttered in a low voice, "...... Cheating money is also different. ”

Cui Jie came back to her senses and said: "The new things made by the husband are not only used by the community, but also used for people's livelihood, but they are not known." ”

"What else did he make?"

Cui Jieqiao's face flushed, and whispered in her ear: "The thing that our woman came to every month, husband and he made a ......"

After a stumbling whisper, the more Jin Xiang listened, the more shocked he became, the more he listened, the redder his face became, and before he finished speaking, he pinched Cui Jie hard, and said ashamedly and angrily: "You're going to die!" Can you say that? ”

Cui Jie giggled and said, "I'll give you a few pieces when I go back, try it when you come to the moon, this thing made by my husband is really easy to use, I was too ashamed to do it before, but after trying it secretly, I can't do without it anymore......"

Jin Xiang was extremely angry: "You still say, you still say!" If you are really married, your skin is much thicker than before! ”

Cui Jie didn't relent: "There are still ......"

"What else?"

"The husband also made something like a hood, saying that it can support our women's ......" Cui Jie continued to whisper in her ear.

Jin Xiang was dumbfounded, gasped, and his face was as red as a boiled crab.

"Phew! Shameless, disciple! Jin Xiang scolded hatefully.
