Hongwu Survival Guide

Chapter 328
Thinking of resting for a day, Qian Tang rushed all morning, but in the afternoon, he still couldn't make it.

First, Jinling University sent people to pick up the books, intending to take them back and copy them.

Zhu Yuan personally ordered, no matter if it was the earlier "Song Huiyao", "Taiping Yulan" which he got only a few years ago, or other things, they should be taken away.

Moreover, all good things are done.

After all, there are not as many books on my side as there are in the palace, not to mention, there are a large number of Yuan Dynasty classics and archives brought back from Dadu last year, which Zhu Yuan had already considered.

Anyway, it's the same word.

copy.

Speaking of this, many people may subconsciously think that printing technology appeared so early, and movable type printing has already existed, so why copy books?

Because this is reality.

In this day and age, printed books are, after all, a minority.

After a few carts of books were taken away, news came from the cement workshop that the first batch of prefabricated slabs poured years ago were basically dry and ready for some tests.

Obviously in order to accommodate Zhu Yuan, Shen Quan personally brought a batch of prefabricated panels to Houhu Medical University on the north bank of Xuanwu Lake.After all, if it is to be used, the laboratory of Houhu Medical University and the planned penicillin workshop must be the first batch.

Zhu Yuan also wanted to take a look at it immediately, so he left the lake from the back door of the mansion and rushed to the University of Medicine by boat.

In an open space on the north side of the laboratory courtyard, where a new laboratory is planned to be built, a total of ten prefabricated panels were brought in this time, with different lengths and widths.

However, when Zhu Yuan arrived, the first thing he noticed was the cart that pulled the prefabricated panels here.

A cart with brand new bearings.

You should know that even with holes, the prefabricated panels are very heavy. There is a little bit of data here, and the average is around 500 kilograms, and the heaviest sample even exceeds [-] kilograms.

With such a weight, it would be very laborious for ordinary cars to pull at this stage. Even if they can be pulled, the key is that the wear and tear on the vehicle will be great.In comparison, the cart with ball bearings is not only easier to drag, but also minimizes wear and tear.

Of course, because of this extension, Zhu Yuan thought of something else.

artillery!

In human history, artillery appeared much earlier than most people imagined.However, one of the biggest limitations encountered by artillery is transportation.

An iron cannon that weighs thousands of catties.

Too heavy.

Therefore, even if one or two doors can be transported, ten or twenty doors, or one or two hundred doors, it will become a problem.In the era of lack of accuracy, artillery cannot be used intensively on a large scale, which is of little significance.

A key to solving heavy artillery transportation, it is simple to say, ball bearings.

The world is so simple and wonderful.

When Zhu Yuan was thinking about this, Dai Sanchun and Shen Quan came to him together. After saluting, Dai Sanchun said: "My lord, do you want to test now?"

"Of course, it's all here," Zhu Yuan said, and looked at Shen Quan with a smile: "Don't let me down."

Shen Quan obviously didn't have much self-confidence, he just said: "Your official...do your best."

The method of testing is still simple and crude.

standing people.

Zhu Yuan ordered the smallest piece, one foot long, one foot wide, and three inches thick.

The two sides were padded up, suspended half a foot high, and began to order people to stand up.

It was full in a blink of an eye.

They squeezed as much as possible and hugged into a ball, and finally squeezed twelve big men.

It was estimated that the total amount would be [-] jin. As a result, the narrowest and thinnest prefabricated panel remained motionless.

Still not right after thinking about it.

The total amount is still too small, after all, the density of people is close to that of water, which is too low.

Simply prefabricated boards stacked prefabricated boards.

The smallest piece was still at the bottom, and people lifted the others and pressed them up.

When five prefabricated panels of different sizes were pressed horizontally, the total weight was judged to be more than 3000 catties. Moreover, the centers of gravity of the five prefabricated panels were all biased towards the middle, and the bottom one finally broke and collapsed.

Not broken.

Because, among them, steel bars have been added, so it is only broken.

Let people carry away the rest of the prefabricated panels, and let everyone look forward together...Look...Look...

then.

Ok.

Is this good, or bad?
Dai Sanchun and Shen Quan looked at Zhu Yuan together.

Zhu Yuan thought about it and said, "It should be good."

As he spoke, he took the clipboard from the hand of the official in charge of recording, which also appeared in Mingzhou and gradually spread.

Zhu Yuan turned a page and wrote while drawing to the two people standing on his left and right: "For formal construction, the prefabricated panels should be arranged horizontally. If it is multi-layered, the force is mainly at the two ends, and the middle... ...Well, I think what should be calculated is the force limit per unit area. What we just demonstrated is basically the weakest part in the middle of a prefabricated panel. The actual situation will not be like this...Anyway, even if it is 3000-[-]% of the building, the single I don’t think it’s a problem for a block with a load of more than [-] kilograms. Just like just now, there are so many people crowded on one board, it’s no problem, not to mention that it will definitely bear the same force in the future.”

After Zhu Yuan finished speaking, Dai Sanchun nodded slightly, and Shen Quan couldn't help but add: "What's more, my lord, even... even if it breaks, there will be no major problems for a while if there are steel bars connecting it."

As he spoke, he gestured towards the broken prefabricated board not far away.

Zhu Yuan also agreed.

However, I still plan to test a few more times.

So another prefabricated board was replaced, and the load-bearing test was carried out again, and there were more patterns.

As a result of the test, five of the ten prefabricated panels that were delivered were broken, but compared to the original one, the rest...better able to withstand it.

Have some final discussions and make a quick decision.

Go dry.

Dai Sanchun couldn't wait for this. He wanted both a new laboratory and a better penicillin workshop. Both of them needed prefabricated panels and cement.

However, Zhu Yuan was more conservative.

Instructions here, you can build a simple two-story building first, the traditional one, with three rooms upstairs and downstairs, to try the effect.After all, it was only a separate test of prefabricated panels before, and no one has seen how it would be used to build a house.

Even if you think it should be better, seeing is believing.

There are also considerations for choosing a small building instead of a bungalow.If it’s okay to build small buildings, then bungalows are no problem.

Dai Sanchun and Shen Quan also agreed.

It's simple.

Moreover, he gave Zhu Yuan a guarantee that it would be completed within ten days.

At first glance, Zhu Yuan thought it was a bit long.

I remember once, a building with a height of several hundred meters could be completed in less than a month, you guys...

Thinking about it again, it will take more than half of the time just to make the prefabricated slabs. After all, the prefabricated slabs are poured out, and it takes several days just to wait for the natural drying.

This year, after some more discussions, the matter was finalized, and Zhu Yuan was not able to leave.He was dragged by Dai Sanchun to the front laboratory courtyard, and discussed some experiences related to penicillin that he recently discovered.

Furthermore, what Dai Sanchun was looking forward to the most, Lao Zhu issued an edict the day before yesterday, when he was still in the fourth day of junior high school, asking all provinces, states and counties of Ming Dynasty to donate Penicillium strains to Jinling for screening.

When I got home, it was another evening.

Don't even think about resting tomorrow.

Lao Zhu has sent word that tomorrow morning, there will be a meeting to discuss the matter of Jinling Military University.

Soldiers, the great event of the country.

Zhu Yuan threw out the plan of Jinling Military University, and had talked with Deng Yu before, but it was far from enough.Now that Chang Yuchun is back and the Ministry of War has been established, and Lao Zhu himself can't let go too much, let's discuss it carefully tomorrow.

In the blink of an eye, it's another day.

The seventh day of the first month.

In the early morning, I felt very good, because there were cherry and plantain on the left and right, the two women were not as thoughtful as Zhuang Liuniang, but it made Zhu Yuan feel at ease.

I didn't have much breakfast, arrived at the imperial city, came to the East Pavilion on the left of Fengtian Gate, there was still some time before the appointment.

Zhu Yuan first came to Lao Zhu's study and talked about the prefabricated panels yesterday.

Lao Zhu also expressed his awareness.

In the early court, Shan Anren mentioned it, and also said that he would build a two-story building at the cement workshop in the next ten days to see the effect.

Zhu Yuan remembered that what he was thinking about yesterday was to start construction at the University of Medicine.

but……

Ok.

Although I quickly understand some people's thoughts, this is a small point, it doesn't matter.

Lao Zhu immediately mentioned another one: "Wenzao, do you still remember?"

"I helped deliver the letter for so long, how could I not remember it," Zhu Yuan smiled, and immediately realized: "My ancestor, Wenzao is back?"

When Zhu Yuan was in Mingzhou, in order to ensure the confidentiality of the communication with the 23rd grandson of his own treasure, Lao Zhu specially asked an arch guard, Baihu Wenzao, to be the messenger.

When Zhu Yuan returned to Jinling, Wen Zao was also promoted, and, if I remember correctly, he was sent to the Northeast.

"Come back from Koryo, landed in Mingzhou, injured, still recuperating, I asked him to come back later." Saying this, Lao Zhu also took a sandalwood box from the side and handed it over: " Take a look."

Zhu Yuan opened the sandalwood box.

Inside is a mass of things wrapped in white silk.

Zhu Yuan opened it, and saw some... black soil.

Black soil? !
Immediately reacted.

This is the black soil in the Northeast. I told Lao Zhu before that it takes hundreds of years to grow an inch of fertile land.

Unexpectedly, Lao Zhu was so caring, even...

Zhu Yuan couldn't hold back, and curled the corner of his mouth: "My ancestor, this sandalwood box contains a bag of black soil, isn't it too wasteful?"

Lao Zhu, who was flipping through a memorial, glanced at someone who was not doing the right thing, didn't answer this question, and handed over another letter, saying: "Wen Zao and his party went all the way north, first found this black soil, and then continued north." Okay, after passing the Beishan border, I felt that the days were getting shorter and shorter, and the weather was too cold, so I had to go back. On the way back, I met Nahachu and was entertained. I left and wanted to go back to the pass, but I was hunted down. We had to divert to Korea and found our Ming merchant ship, so we had to return to Mingzhou."

As Lao Zhu said, Zhu Yuan also quickly read Wen Zao's secret letter.

It is roughly an introduction of what I have seen and heard along the way.

Putting down the letter, Zhu Yuan thought for a while and said, "It should not be the people sent by Naha, otherwise, the other party can kill Wen Zao and the others on the spot."

"That's right," Old Zhu said, "The Yuan Dynasty is destroyed, and the Northeast side...the orthodoxy will be lost after Naha's departure. Not all the tribes outside the pass want to belong to our Ming Dynasty."

Zhu Yuan asked: "My ancestors captured Naha Chu back then, what do you think of him?"

Lao Zhu recalled it for a while and said, "It's just that he has a good background."

Zhu Yuan said: "If this is the case, the Northeast...may be in chaos."

Insufficient in ability, and without the orthodox name support of the Yuan Dynasty, Nahachu's situation can be imagined in the northern tribes where strength is respected.

"It's beyond the reach of the whip," Lao Zhu nodded, feeling emotional: "Even if we have spare power now, we must look for the true north. As for the northeast..."

He said and shook his head again.

"Does the ancestor think that it is possible to persuade Naha to surrender?"

"It's just that Naha surrendered, what's the point?" Lao Zhu pointed to the letter that Zhu Yuan had just read: "You have seen it, a commander who can't even protect his guests, if he doesn't surrender, or returns There are more people who obey him, if they want to surrender to our Daming, they will be chopped down in no time."

After Zhu Yuan thought about it a little, he had to admit that there was a high probability that this would be the case.

It is also a simple truth: after the ancestors are rich, it is actually not easy to surrender to others.

This is even more so for the Mongols. After all, the Yuan Dynasty was destroyed less than a year ago, and many people will instinctively harbor all kinds of fantasies about a comeback.
