Chen Zhengtai took pen and ink, wrote and painted on paper, in fact, he didn't know a lot of things, but the general principle is still the same, as for whether these craftsmen can understand it, is another matter.

In fact, in order to solve the problem of repeating crossbows, the essence is to solve the problem of standardized production.

Each arrow and bow are required to be consistent, not the same as in the craft, and each crossbow and arrow is different, and the results cannot be matched with each other.

Therefore, there must be a ruler and a special production improvement.

You can't rely on the craftsmanship of a few craftsmen to decide whether something is good or bad.

The skilled craftsmen of ancient times were indeed able to create incomparable and exquisite works of art, which was enough to amaze later generations, but if it was large-scale production, it was impossible to count on the level of craftsmanship of the craftsmen.

Putting down the pen, Chen Zhengtai said to Chen Donglin: "Take it back, study it well, if there is something you don't understand, you can ask more people, within three months, it can't be done, and it's useless to keep you." There are too many of our Chen family, and there are still a lot of them, and they are still mining in the mountains, it's pitiful to think about. ”

Chen Donglin's face turned blue with fright, and he hurriedly said: "Uncle, don't worry, if my nephew can't do it, I don't need to send it to the mine, I will hang myself to die." ”

Hearing this, Chen Zhengtai was relieved, people were forced out.

The reason why he cares about the crossbow is because the prince's guards are scarce, full of battles, and the soldiers are only 1,500 people, so a small number of military horses, if they want to exert enough combat effectiveness, then they must spare no effort to increase the output of firepower.

…………

Xiazhou ......

A man named Chen Zhengdao arrived at the Xiazhou Thorn Mansion.

Thorn Shi felt strange about this uninvited guest, but after the other party took out the door sticker, this Thorn Shi looked at the door sticker of the Chen family, but became cautious.

After all, this Chen Zheng was introduced into the mansion.

Chen Zheng went to the assassination history to pay a salute: "I am ordered by the head of the family to come to Xiazhou, and in a few days, I will go deep into the desert. ”

The history of the thorn is called Huang Yan, Huang Yan is the head, the Chen family has been in full swing recently, which many people did not expect, in the face of such a newly rising family, the world's wang clan has adopted an attitude, that is, it should be polite, but it is necessary to keep a certain distance.

After all...... Recently, who knows if they can last long, the Chen family's county prestige does not match their current worth in the eyes of many people, so they can neither offend them, but also try to ...... Don't marry them, because the Chen family has a shallow foundation, and no one can predict whether it will fall in the future.

Even if you really want to marry a daughter, then find a widow...... Or the daughter of a concubine.

Huang Yan then said kindly: "Oh, the old man has also heard of Chen Zhan's name for a long time, what's the matter, you want to go to the desert, what's the matter?" ”

"The head of the family said that the Tiele Department and Tuyuhun attacked each other, in his opinion...... The Tiele Department will lose this battle, so I was ordered to go deep into the desert and find a way to recruit the capable people of the Tiele Department, and in addition, see if there can be other gains. ”

Huang Yan glanced at Chen Zhengdao, he was a little suspicious.

As the history of Xiazhou Thorn, no one knows the situation in the desert better than him, after the Turkic weakened, Tiele and Tuyuhun in order to compete for hegemony on the grassland, both sides continue to kill, it stands to reason that Tiele has more men and horses, even if he does not win, but he will never be defeated by Tuyuhun, so according to his estimate, either the two sides are stuck in a stalemate and are evenly divided, or Tiele annexes Tuyuhun.

What's even more puzzling is this person named Chen Zhengdao, this person is also a close relative of the Chen family, it stands to reason that it is very dangerous to go deep into the desert, generally in such a situation, the descendants of the family will not be allowed to go, but this Chen Zhengdao in front of him is dark-skinned, where is the appearance of a family child, but like an ordinary pawn of a peddler.

"Tiele is going to be defeated? Why hasn't the old man heard of it? ”

This man, nine times out of ten, is a madman.

Huang Yan's heart suddenly lost interest in the person in front of him who claimed to be a disciple of the Chen family.

"This is the head of the family."

Huang Yan sighed, his attitude suddenly cold, and then said: "If you want to go deep into the desert, you need a guide, this point, the old man will arrange a few healthy soldiers, into the desert, horses and grain, you yourself have to prepare more, you go all the way to the west, you need to cross the Turkic Department, and after walking hundreds of miles, you can reach the boundary of the Tiele Department, the old man suggests that you disguise yourself as a merchant, in the desert, people are often very friendly to the merchants, if there are no merchants, they would have eaten the northwest wind a long time ago." ”

Huang Yan explained, and then instructed the scribe to select the guards, and then sent Chen Zhengzhi out.

He held the prayer note in his hand, and couldn't help muttering in his heart: "Either this Chen Zhengzhi is a liar, or ...... Then Chen Zhengtai is a madman......"

Immediately, he threw the prayer post aside.

Even if he is a liar, he doesn't care, after all, it doesn't matter, but if it is really the Chen family, he doesn't want to offend.

So he sat down and prepared to repair the book, since he helped the Chen family, he had to let the family remember his kindness, so this letter was sent to Chen Zhengtai, and he explained what happened, and then asked Chen Zhengtai if the identity of this Chen Zhengtai was suspicious, and at the same time expressed his admiration for Chen Zhengtai, of course...... Among them, it is indispensable to explain the long family relationship between the Huang family in Xiazhou and the Mengjin Chen family, even if he married his daughter hundreds of years ago, a few decades ago, the two families had children who were classmates, and they could also write a big book, after a letter was written, Huang Yan couldn't help but laugh.

The scribe on the side said, "Ming Gong, I don't know why I'm laughing." ”

"This Chen family was also a family with a county reputation at the beginning, but now Shengsheng has tossed himself into an upstart, but the old man has to talk to him about the origin, the old man is happy in the bitterness. Hum...... Tiele was defeated...... It's a shame for his whimsical ......"

Huang Yan put down his pen with a look of contempt, and was about to tell the scribe to send the letter.

Unexpectedly, at this time, someone from outside hurriedly came: "Assassin Shi, Assassin Shi, I got urgent news from the Turks...... Tiele thirteen surnames infighting, Tuyuhun took advantage of the situation to attack it, Tiele suffered heavy losses, nine surnamed Tiele all surrendered, the remaining four surnames, eight or nine out of ten, were slaughtered cleanly, this is still the territory of the remnants of Tiele who fled to the Turkic people, and only then did I learn the news......"

"What?" Huang Yan suddenly got up, he was a little confused, this is really ...... What do you say?

"So...... Isn't it that in the future, this desert will be the world of Tuyuhun? "He is a thorn in history, and he knows no more than the need to maintain the balance of power on the steppe, but now...... This balance of power was broken in an instant, which Huang Yan did not expect.

He thought suddenly...... Chen Zheng, who had just been sent away, arrived at ......

That Chen Zhengtai ...... What a crow's mouth.

"Come, immediately take pen and ink, and repair the book...... Playing. ”

……

Two guests came to Erpigou, one was a princess and the other was also.

Chen Zhengtai was a little confused, but he saw that Princess Changle and Princess Sui'an came together, hugging their guards and eunuchs, and when they arrived at the door, the two got out of the car, and Chen Zhengtai hurriedly greeted them: "What kind of wind did the two junior sisters blow in?" ”

When I heard it blowing, it was blown by the wind...... Princess Changle felt a little unhappy in her heart.

Because in this era, there is obviously no saying that the north wind blows.

Princess Changle thought to herself...... Did he deliberately sarcastically mock me for being weak? Yes, I'm too slender and not plump enough, and he must hate me for being like this.

So his pretty face was tense and he didn't say anything.

Princess Sui'an didn't think about it so much, she said with great interest: "Father said...... When I reach the age of tomorrow, I will leave the palace, and when the time comes, I will inevitably build a princess's mansion, and he asked me where the princess's mansion is located, and I said to think about it again, and the royal sister will ...... with me today."

Princess Changle corrected Princess Sui'an and said, "It's not Sui, you invited me." ”

Princess Sui'an began a brief break.

Did you invite yourself?

Doesn't it see?

It was clear that she said that he would come to see it too.

All right......

Princess Sui'an bowed her head: "Yes, I invited the royal sister to come out and see where it is suitable to build." I know that my brother understands everything, so I came here to ask for advice. ”

"Well." Chen Zhengtai said: "This is easy, you come in and talk." ”

"Go in?" Princess Changle was curious: "But...... Isn't it time to walk around and see the feng shui and the topography? ”

Chen Zhengtai said with a smile: "Who said that you must see it with your own eyes, I have a map, and the mountains and rivers in it are all in the map, but it is detailed, and the two junior sisters will know it when they see it." He said while continuing: "Since it is the princess's mansion, of course we have to find a good place, I think Erpigou is good, we are about to build a new East Palace in Erpigou, and there are countless residences, and the university hall is also going to be expanded, plus the princess's mansion of the junior sister, isn't this everything complete?" If you come, it's best that when you come to the place where your princess's mansion is located, I will take a name and call it 'Wutong Fang'. ”

"Sycamore?" Princess Sui'an looked surprised and a little puzzled.

Princess Changle smiled lightly: "He is saying that you are a phoenix, the phoenix is not a sycamore, and the place where you live is not the sycamore?" ”

Princess Sui'an suddenly realized: "Senior brother is really knowledgeable, he really understands everything." ”

Princess Changle coughed lightly, thinking to herself...... But I've explained it to you, so why don't you say I understand?

Chen Zhengtai nodded repeatedly: "What Senior Sister Changle said is not wrong, that's what it means, haha...... Speaking of this princess's mansion, I have a lot of experience, the two sisters please sit down, drink tea first, I slowly tell you, this project, you don't have to let the Ministry of Engineering come, I see......... Leave it to the construction team of Erpigou, my construction team is particularly exquisite...... Make sure that the teacher sister is satisfied. ”

The fifth chapter was delivered, so tired, I wrote so late every day, I went to sleep, and I asked for a monthly pass at the beginning of the month.
