Hongwu Survival Guide

Chapter 59 It's Too Dark

I struggled a little bit about the title, thinking that since it was the order of Lao Zhu, it would be impossible to drive the four little eunuchs away, Zhu Yuan didn't mention it for the time being, and turned to other things.

He Xuan sent another letter from Lao Zhu.

Zhu Yuan opened it on the spot.

Lao Zhu first said that all the tokens had been received, and then asked Zhu Yuan to pay attention to his body and not to be tired, and he had to be taken care of by four eunuchs in daily life.

Then it's business.

The first one concerns the collection of timber for shipbuilding.

Lao Zhu sent 10 taels of silver, and also squeezed ten more ships over, and gave Zhu Yuan another cheap move, allowing coastal residents to use wood to deduct this year's tax.

When discussing shipbuilding, Zhu Yuan also thought of using taxes as offsets.

However, on the one hand, this is not something he can decide arbitrarily. It needs to be decided by Lao Zhu, just like the tax exemption for fishermen before.On the other hand, because he already has an idea and intends to get wool from the sea merchants, there is no need to use taxes.

During this period of time, all sea trade merchant ships transferred to Mingzhou have completed tax collection, and the accumulative income of Ying Hai Division has exceeded 4 taels of silver. Considering the follow-up plan, even if there is no supplementary replacement plan, Zhu Yuan can still complete the timber. call for.

Unexpectedly, Lao Zhu still thought of it for him.

Not only gave another cheap move, but also sent 10 taels of silver.

With only this 10 taels of silver, plus a tax deduction, even if Zhu Yuan didn't have the previous plan, he could still get the wood collection done.

It's like Lao Zhu helped his precious 23rd generation grandson to handle a big event.

Not only that, Lao Zhu probably also realized a certain problem, and he also stated in the letter that he had sent a letter to the troops of the Southern Expedition, strictly ordering the generals not to detain any sea ships without authorization, but to send them all to Mingzhou.

After Zhu Yuan read this, he couldn't help feeling his "system" and his "grandfather" again.

No.

It's the ancestors!
How did that song sing.

Only ancestors are good in the world~~~A child with ancestors is like a treasure~~~
Like a treasure!

Then read on.

The second one is about Zhu Yuan's work diary.

Lao Zhu asked not to use the previous post, so he specially sent a team of soldiers from the Guard Division, and these people will be responsible for all the correspondence in the future.

Zhu Yuan paused briefly after reading this.

It seems that even if he can't reach the level of "Book from Heaven", Lao Zhu still takes his work logs very seriously.

After thinking about it, it is indeed very important.

When dictating, except for not directly pointing out a certain fact, Zhu Yuan said many things, for Lao Zhu who had read "Book of Heaven", he could understand at a glance, that is, all kinds of things in the "next" hundreds of years.

It really shouldn't be posted.

As for the matter of asking the woman around him to write for him, Lao Zhu didn't mention it.

This is a good thing.

After all, how to mention it, let His Majesty praise them a few words?

Not suitable.

Not mentioning is the default.

At the end of the letter, Lao Zhu told Zhu Yuan again, telling him not to be anxious or tired, it is best to be safe and stable.

It's okay to say that things go wrong.

After reading this letter, Zhu Yuan felt more and more that Lao Zhu really regarded him as his 23rd grandson.

You know, to put it bluntly, Lao Zhu treats his subordinates like a mule. This is due to his personality. On the other hand, Lao Zhu also treats himself like this for decades. Before I start, I start first'.

But for children and grandchildren, Lao Zhu is a typical Chinese parent.

On the surface, he may be stricter with the children, but Lao Zhu wished to pass on those who could be given to his children and grandchildren. This point, from the strong relationship between the "Prince" and the "Minister" who are both at the first rank, have an annual salary of fifty thousand shi and the other one thousand The comparison is evident.

Most people know the allusion of '[-] stones', but they may not know that there is actually a long list after that, even the horse feed of the children and grandchildren's family is considered, and it is specially listed in the salary list.

Zhu Yuan obviously felt that he was receiving similar treatment more and more.

Thinking of this, Zhu Yuan put the letter back into the envelope, put it away solemnly, and looked at He Xuan again: "Is there anything else?"

He Xuan continued.

In addition to the ten large ships and 10 taels of silver mentioned in the letter, there is also a batch of crystals.

Jiang Zuosi recently confirmed the location of a very extensive crystal deposit, which is located in Haizhou, Huai'an Prefecture.

Zhu Yuan asked a few questions to confirm the location.

Later, Donghai County, Lianyungang, the famous hometown of crystal, I heard a few words by chance when I bought crystal utensils in my previous life.

After chatting for a while, Zhu Yuan asked Xieyi to take He Xuan and the others to settle down after the matter was finished.

Both Zhao Xu and Zuo Qi started to lead troops, and they are already the fifth-rank Qianhu. It is not appropriate to let them be in charge of all kinds of trivial matters in the mansion. Since Lao Zhu sent a few eunuchs here, they can be cultivated into the outer court Steward.

As for the inner house.

Zhu Yuan was not really indulgent, so he didn't let a few little eunuchs get involved.

I really can't get used to it.

Later, I saw the guard Baihu who came with He Xuan, named Wen Zao, a short and stocky man about 30 years old.

Of course Zhu Yuan knew the nature of the Gongwei Division.

Old Zhu sent Wen Zao here, in addition to being responsible for delivering the letter, he should also inquire about some news.Of course, ever since Zhao Xu and Zuo Qi were promoted to Qianhu and confessed to Zhu Yuan some of Lao Zhu's confessions, Zhu Yuan knew that his ancestors no longer monitored him.

What's more, it doesn't matter even if it is monitored.

Except for one of the biggest secrets, Zhu Yuan really has nothing to hide from Lao Zhu.

After talking about the details of sending letters in the future, and dismissing rumors, the sky also darkened.

Zhu Yuan ordered dinner to be served directly in the hall on the garden side, and asked to call Qingniang's two younger brothers.

Seeing people, Zhu Yuan once again had a strange feeling.

The kind I saw the green tea girl at the beginning.

Because the "Guier" and "Nieer" mentioned by Qing Niang, one is 29 years old and the other is 23 years old.

Fortunately, Zhu Yuan is just a boy's skin, and the inside is bigger than both of them, so it's just weird.

After the ceremony, everyone took their seats.

The four of He Xuan got into the mood very quickly, and took the initiative to take charge of entertaining, arranging the tableware, and delivering the dishes, very skillful.

After all, Li Gui and Li Bian were scholars, based on their clothes and other details, they could faintly feel the identities of the four eunuchs, but they were not sure. After all, according to the etiquette system, how could this be possible?

During the serving time, Zhu Yuan also noticed that both brothers were dressed in old clothes.

Thinking about how decently dressed the two Nizi families, Xieyi and Liubai, were when they met for the first time, Fu Shou probably wouldn't favor one another in this regard, but just smiled.

I don't feel anything.

Zhu Yuan has never been obsessed with morality and cleanliness, and believes that no matter what personality type, if you use it well, you are a talent.

Ask about the situation along the way.

Sure enough, they still took the family with them. The seven aunts and eight aunts around the Li family, a total of 96 people, except for the two brothers Li Gui and Li Nie who Zhu Yuan explained, all went to Jinling.

He also mentioned that Fu Shou gave the settlement fee again.

However, probably drawing on the experience of being returned last time, the family only gave ten taels of silver this time.

Zhu Yuan didn't say anything after thinking about it.

When the water is clear, there are no fish.

What Zhu Yuan hopes is that the people around him can have a sense of proportion, instead of being a fish in clear water.

So while eating, he turned to other daily topics, and Zhu Yuan quickly figured out the general characters of the two brothers.

The youngest, Li Gui, is somewhat 'pedantic', but not to the point of 'rotten', cautious and respectful.The fourth brother, Li Bian, was very active in his mind. Zhu Yuan guessed that the idea of ​​the two brothers wearing old clothes to see him should be Li Bian's idea.

When the dinner was about to end, Zhu Yuan drank a small bowl of chicken soup and finally asked the two of them, "What are your plans for the future?"

During the meal time just now, the two Li brothers only felt that Zhu Yuan's way of speaking... could be roughly understood, and both felt weird, but they didn't dare to question it.Hearing this question, the two of them put down the tableware together and got up at the same time. As the elder brother, Li Gui said: "My lord, the Li family is grateful for your kindness in saving your life. My two brothers have nothing to repay you, and they are only willing to let your lord dictate."

Having said that, the two knelt down together again and saluted.

Zhu Yuan didn't stop the two of them, he had small arms and legs, he couldn't stop him, he had given up struggling for this kind of thing, when the two brothers stood up, although he noticed that Li Bie's expression was mixed with other things, he still pretended not to know and nodded. : "In this case, let's start working tomorrow, I happen to be short of manpower."

Calling the two brothers over is mainly for this purpose, apart from looking at their character.

The two brothers saluted again.

After dinner, Zhu Yuan called Zuo Qi and asked him to take the two of them to settle down. By the way, he gave them a copy of "Sketch Techniques" and "Basics of Mathematics", asking them to learn as soon as possible.

As soon as the dinner plates were removed here, Dai Sanchun rushed over with Cui Shen, a jade craftsman.

Because I heard that another batch of crystals has been sent.

These days, Dai Sanchun kept talking about the microscope, but Zhu Yuan always disrupted his plans.

The batch of jade craftsmen sent by Lao Zhu earlier was originally intended to serve the Tai Hospital, so Lao Zhu also set up a medical device bureau under the Tai Hospital, and appointed Cui Shen, who came with Dai Sanchun, as the head of the medical device bureau , is eight products.

Zhu Yuan brought all those craftsmen here this time.

Then, not only these people have been grinding the convex lens needed for the telescope in the past few days, but in the past few days, they have been recruited by Zhu Yuan to grind the copper balls in the bearings needed for the hydraulic saw table.

I have to say, compared with ordinary coppersmiths, let these craftsmen who can make all kinds of exquisite jade objects grind copper balls, um... rounder.

It wasn't until Zhu Yuan thought of another method later that Cui Shen and others were relieved.

Very simple, car beads.

I remember that various wooden bead strings were very popular in the previous life. In fact, a little understanding can tell that someone behind the scenes is promoting the hype, just like fried tea, fried flowers, fried shoes, or even fried shallots and garlic.

The hype is a bit overdone, and Che Zhuzi has become an Internet buzzword because of this.

Everything can be a car bead.

The simple hand lathe is made, and there is no need to labor the top jade craftsmen to do such trivial things.

Zhu Yuan also ordered to build a hydraulic lathe by the river today, which will be more efficient by then.

Dai Sanchun was originally an old-fashioned doctor, but now he looks like an old-fashioned university teacher, with a thick stack of drawings, charcoal rulers, and a newly made vernier caliper.

Cui Shen, who is more than 50 years old and is similar to an assistant, is carrying a wooden box, which contains lenses and other related items.

The vernier caliper was thought of by Zhu Yuan a few days ago.

To match the lenses, you must first measure more accurately. In this era, the most accurate measurement method that Zhu Yuan can think of is a vernier caliper.

The principle of vernier calipers is actually very simple.

Just like before, the scale of the main scale is 1 cm, and the scale of the secondary scale is 0.9 cm. Both are divided into ten parts, and the gap between them is used to reduce the accuracy to 0.1 mm.

The current one inch is too long. When Zhu Yuan gave a suggestion, he also suggested that one inch can be divided into two, and then continue to be precise.

So the vernier caliper in Dai Sanchun's hand naturally got its name: half-inch caliper.

In order to make a microscope, Dai Sanchun, a 'university teacher', kept digging information from Zhu Yuan. He can be regarded as an 'optics expert' in this era, and he is still studying mathematics at the same time.

These days, Dai Sanchun discovered a method to determine the focal length of the lens.

It's actually very simple.

Focus on the light, gather points, and measure the distance.

Zhu Yuan didn't know if this was the standard focal length of a convex lens in his memory, but he had to admire Dai Sanchun's carefulness. It was a very common phenomenon. He even used a magnifying glass to show everyone how to ignite a fire in the sun.

I was very impulsive at the time.

Want to catch an ant.

At this time, the ants have not yet come out of the nest, and escaped unharmed.

However, I didn't expect the focal length issue.

The two spread out various blueprints on the round table where they had just had dinner in the hall, and discussed with divergent thinking. According to Dai Sanchun's discovery, they confirmed one more point. Perhaps, the focus of the concave mirror has been forgotten, but it can also be used similarly. method to measure, or infer.

After all, the curvature of both a concave mirror and a convex mirror is only a part of a circle.

Now with vernier calipers, the measurement accuracy has been greatly improved, so you can try to develop a set of standards.

The two wrote and drew and discussed for more than half an hour on the spot to find out the lens for a demonstration. Once again, Zhu Yuan's inspiration in this regard was wiped out, and Dai Sanchun returned to the topic and assembled the microscope on the spot.

Similar to the appearance in Zhu Yuan's memory.

But a simple straight.

It's not that it's impossible to make refracting lenses now, but it's too troublesome and unnecessary.

Picking different eyepieces and objectives, trying various things, but still no results, at best just some points of light with no content.

Zhu Yuan was also thinking about it, remembering that he had done a water drop microscope in his previous life, and he could indeed see things. He was about to remove the lens from the cylindrical lens and reassemble it. Looking around, he found a problem: "It's too dark, I need to light a few more lights..."

After saying this, Zhu Yuan suddenly froze.

too dark...too dark...too dark...

Look at the microscope that Dai Sanchun is fiddling with. The eyepiece, the objective lens, and the glass slide are right.

Something is missing.

what

what……

"reflector!"

When he was about to pull his hair, Zhu Yuan finally slapped the table and shouted.

And remember, the amount of light that can get into the microscope is very low, so a reflector is needed to fill in the light.

No wonder it's always been dark, occasionally you can see bright spots, and there's no content.I always thought it was a focus issue or something.At the moment, I finally realized that it was just one word, it was too dark.

Ok.

Well...that's three words.

Dai Sanchun and Cui Shen saw Zhu Yuan suddenly slapped the table and yelled, and at the same time looked over suspiciously, with worry in their eyes.

But don't...you get sick again?

Zhu Yuan ignored the weird eyes of the two, and was about to explain when a soft male voice came from outside the door: "My lord..."

It's He Xuan.

After finishing the dinner with the Li brothers, Zhu Yuan sent them to rest.

Why are you back?

With a promise here, He Xuan lifted the curtain and entered together with another young eunuch, bowed and said, "My lord, it's Haishi, it's time to rest."

It's only nine o'clock.

Zhu Yuan didn't refuse either, he waved his hand and said, "Wait for a while."

Turning to Dai Sanchun and Cui Shen, they both looked like they had seen a ghost.

Unlike the Li brothers, the two Dai Sanchun knew very well what the palace eunuchs were wearing, and they could confirm it with just a glance.

This……

Why is there an eunuch in someone's family?

Big sin.

Zhu Yuan understood the thoughts of the two at a glance, and was about to explain, but He Xuan said again: "My lord, it is time to let your body rest. Your Majesty strictly orders you not to be tired anymore. If you have any No way, slave... the younger ones don't want to live."

Now... there is no need to explain.

Hearing that it was Old Zhu's order, Dai Sanchun and Cui Shen also relaxed, but the expressions they looked at Zhu Yuan were still weird.

Even if someone is favored, it is too unethical to send eunuchs to serve him.

Cui Shen, who is more than 50 years old this year and can be regarded as an experienced man, also thought of another place.

Zhu Yuan.

Zhu...

'Zhu' ah.

I have to say, he was right.

No reward.

Zhu Yuan saw that if he didn't go to rest, He Xuan would probably turn into Tang Monk's constant chanting appearance, so he could only nod his head.

Finally, he turned around and pointed to the microscope in front of Dai Sanchun: "Below, there is a lack of a light-filling reflector. Make a, um, a flat or concave lens, plate it with silver, or grind a small silver mirror, and install it below. Tomorrow Look outside in good light. That's it, I'm going to rest."

After finishing speaking quickly, before He Xuan was about to start reading again, Zhu Yuan and Dai Sanchun gave two simple salutes and left the hall.
