Everyone in the world knows that Qingzhou has implemented the salt and iron official camp, and set up an iron smelting department, which belongs to Dasi Nong, and produces iron products for sale. But what they didn't notice was that inside the Shaofu, there was a divine machine supervisor!

Shaofu's Shenji Supervisor is responsible for the manufacture of the army's weapons, armor and other military supplies, and in Shaofu's Shenji Supervisor, there is a more advanced iron-smelting technology than the Iron Smelting Division - the steel filling method!

Shaofu is responsible for the Son of Heaven, equivalent to the emperor's steward, and the establishment of a divine machine supervisor in Shaofu is also a powerful force for Liu Xie, which is conducive to the central government's control of the army!

Chu Yi took Feng Cai to the Shenji Prison, and he is now also a Shenji Prisoner.

"Subordinate Chen Wu see your lord!" As soon as Chu Yi entered the Divine Machine Prison, someone immediately came over to pay a visit.

His name is Chen Wu, and he is also a native of Nanyang, and he came to Qingzhou with the idea of giving it a try when he heard about the recruitment order, and later after Cui Yan's assessment, Chen Wu is indeed a skilled craftsman, with exquisite craftsmanship, and even can copy the ground motion instrument of his fellow countryman Zhang Heng!

Although Chu Yi was nominally the leader of the Divine Machine Supervisor, the affairs of the gods were basically handed over to Chen Wu to be in charge of.

"Well, get up, I want your stuff to be ready."

Chen Wu scratched his head: "This ...... Adults let us get too many things, I don't know which one it means? ”

Chu Yi smiled and asked, "What have you done?" ”

"The four-wheeled cart you asked for has been completed, as well as the armor you wanted, and we are now working on the crossbow according to your orders."

Chu Yi's face was happy: "The steering device of the four-wheeled vehicle has been figured out?" ”

A hint of pride flashed on Chen Wu's face: "Yes, after being mentioned by the adults, we have been thinking about it for a month, and we have finally created this!" ”

"Pull it out and show me!"

"No!"

After a while, several craftsmen drove a carriage slowly.

Four-wheeled vehicles have existed since ancient times, but they are not commonly used, because four-wheeled vehicles in ancient times have no steering device, do not turn around, and are very inconvenient to use, so most of the time they use two-wheeled vehicles.

However, a four-wheeler has a big advantage over a two-wheeler, that is, the weight of a four-wheeler is much greater than that of a two-wheeler! This will greatly reduce the burden of logistics and transportation, and will also reduce the loss of materials in the transportation process! In the many wars that followed, this was a great weapon!

Chu Yi looked at the demonstrations of the craftsmen of the Divine Machine Supervisor and nodded frequently. The technical difficulty of the simple steering device is not high, but ancient China has not paid attention to it, and now that Chu Yi has mentioned it, then after having ideas, the Chinese are still quite fast.

Chu Yi clapped his hands and smiled: "Well done!" I will ask the Son of Heaven for you to take credit, and those who participate in the manufacture of four-wheeled vehicles will be promoted to two levels! ”

In Qingzhou, the promotion of knighthood means that you can have more fields and money, and the craftsmen were overjoyed when they heard this: "Thank you, thank you!" ”

"You have made meritorious contributions to the Han Dynasty and the Son of Heaven, you don't have to thank me!" Chu Yi smiled slightly, and said to Chen Wu, "By the way, take out the armor and show it to me!" ”

Chen Wu asked people to lift out a shelf, and there was a pair of iron armor on the shelf.

This set of armor is different from the previous form of Xuanjia of the Han army, although it is still in the form of armor, but it adopts the method of making a certain curvature of the entire iron plate, and then pressing one by one.

Of course, this is not particularly unusual, after all, this method of piercing armor has already appeared in the Eastern Han Dynasty. However, on both sides of the armor, there is a round piece of iron on the chest and the back of the heart, which is called the round guard, and it was originally something that would not appear for hundreds of years.

This thing can effectively increase the defense of the armor, and it is carried forward on the bright light armor. Now it is naturally impossible to replicate the Mingguang armor of the Tang Dynasty on a large scale, but Chu Yi can learn from some of it.

Using advanced steel filling technology, the performance of the armor is improved, and three pieces of circular protection are nailed to the chest and back of the heart, which can better protect the life safety of soldiers.

"Well, well done." Chu Yi looked around this new type of armor for a while, and said, "Feng Cai, put this armor on and take a look." ”

Feng Cai's little face tightened, looking a little nervous: "No." ”

After a while, Feng Cai walked out wearing this suit of armor again, and his delicate face revealed a heroic spirit.

Yang Wu and the others hurriedly came up and patted the: "Eh, after this female general wears it, she is really majestic, and the women don't let her eyebrows!" ”

Chu Yi glanced at them and asked, "How are you feeling?" ”

"It's okay, I don't feel like there's much difference......" Feng Cai moved his arm and made a bitter face, "It's just a little heavy." ”

"The point is good, and it can save your life at a critical time." Chu Yi patted Feng Cai on the shoulder.

Chu Yi ordered: "That's it, no need to change it, you can let people mass produce." ”

Seeing that Chu Yi was satisfied, Yang Wu hurriedly nodded: "No!" ”

"By the way, how's your bed crossbow research?"

"Is that the three-bow crossbow you're talking about?"

"yes, how are you doing?"

"According to your request, we have roughly done it two days ago, but the current range is far from reaching the sixty zhang you said, at most twelve or three zhang."

"Hmm." Chu Yi thought for a while, twelve or three zhang was almost three hundred meters, but Chu Yi was obviously not satisfied with this, "You guys continue to improve, if you can make the three-bow bed crossbow range reach fifty zhang, you are the hero of my great man, and you will be promoted to the fifth level!" ”

Yang Wu and the others glanced at each other, a trace of ecstasy appeared on their faces, and they nodded heavily: "No, my subordinates must do their best!" ”

No one here discriminates against their "strange and skillful skills", and even uses them a lot, and even many of them have official positions, how can this make them not grateful and motivated?

"How many ring-headed knives have been built these days?"

"My lord, as of yesterday, a total of seven hundred and ninety-six have been forged."

"Let someone send me to my unclothed army today."

"No."

Chu Yi looked at Feng Cai and said, "You quickly change your clothes and armor back, and then go back to the army." ”

"Oh...... Promise. Feng Cai looked at the armor on her body with some reluctance, although it was a little heavy, but she still liked it.

Yang Wu hurriedly stopped: "If this female general likes it, she will dress it well." It's okay, my lord. ”

"If you don't have a template, I'm afraid it will take a lot of work."

"It's okay with this, we still have a set of such armor. If this female general can like this set of armor, she can wear it directly. Yang Wu looked at Chu Yidao ambiguously and flatteringly.

The corners of Chu Yi's mouth twitched slightly, isn't it your eyes that suspect me of Jinwu Zangjiao? Am I like that? sighed, seeing Feng Cai looking at him with a hint of pleading in his eyes, as pitiful as a little beast, he waved his hand weakly: "That's it, that's it." ”
