Stretched out his hand to take the paper fan, opened it and saw that it was a painting, the scroll was not a common ink painting of this era, but the painting techniques of the Song Dynasty, rendering various colors.

I saw that at the bottom of the picture, there were mountains on a side.

The painter of the painting should be a master, but with a few brushstrokes of light ink, he can paint the momentum of the mountains at a glance.

Even the green pines in the mountains painted with thick ink are so freehand.

And the most striking thing is that on the highest peak, in the gravel pile, there is a plum blossom waiting to be released.

Next to the plum blossom, is a green bamboo that goes straight to the top of the fan, the green bamboo can not see the top, just a few branches, two or three green leaves, the arrogance and humility of the hollow bamboo are vividly displayed.

In the upper left corner of the fan, there is a fiery red cloud, and in the center of the cloud, there is an orange sun.

It's like a sunset, and it's like a rising sun.

In the upper right corner of the fan, there is a poem:

"The roots are in the broken rocks,

Insist that Qingshan does not relax. ”

"Poof!"

Zhang Yan couldn't help laughing.

Zhu Cijiong's intentions, Zhang Yan already knows everything.

He pointed at her with a plum blossom ribbon and represented himself with green bamboo, and as for the sunset, he told her that after night was the rising sun......

As soon as she saw this painting, Zhang Yan seemed to see the bad boy again, and he told her that the Ming Dynasty was broken, and the two came from a chaos, and stood hand in hand on the highest peak in the world, sitting and watching the clouds roll up......

The green bamboo can top the rocks and stand proudly in the sky, and the plum can not be afraid of the cold and bloom in early spring, what else can the two of them not break through?

That's it, that's it.

You can have a confidant in life, what else can't you give up?

Qing'er couldn't help but be overjoyed when she saw Zhang Yan smiling: "Queen Mother, did you promise Your Majesty to go back?" ”

She turned around eagerly and was about to pack her bags.

Zhang Yan shook her head:

"Qing'er, you are accompanying the palace for a while, and when the Taoist temple is built, the mourning family will personally make decisions for you and send it to Your Majesty."

Qing'er was embarrassed, and she murmured: "What did you say, Queen Mother?" Qing'er wants to serve you for a lifetime, if you don't go back, Qing'er will accompany the Queen Mother. ”

Zhang Yan shook her head, but didn't say anything.

She wanted to go back, too, but she couldn't!

……

Nanyang workshop.

Zhu Cijiong did not return to the palace directly.

He didn't see Zhang Yan, so he had to give Zhang Yan the fan that asked Zhu Yan to paint, it was a smart woman, and he believed that Zhang Yan could understand what he meant.

Zhu Cijiong, who was unwilling to return to the lonely deep palace compound, simply went to the artillery workshop.

Today is the twenty-sixth day of the lunar month, and the craftsmen in the craftsman's workshop have no holiday.

The battle of Xiangyang was just around the corner, and Zhu Cijiong offered double the pay, as long as the craftsmen were willing to stay and work overtime, then he would directly give double salary.

The Han family is the most hard-working and rich, especially the Henan people who have many people and little land.

This is a place where no war has not been affected, and the suffering of our ancestors is integrated into their blood.

Because of this, they take every opportunity to accumulate more of their heritage......

When they heard that they could get twice the salary if they stayed overtime, no one from the master to the elementary school apprentice chose to go home for the New Year.

The repeated hardships have made Henan people know a sentence - the year is good, the month is good, and the life is not good!

If they can save an extra penny, they will never let it go.

People here lack flexibility, but once they have a stable environment, as long as the policy is equal, they are always the first to get rich......

Wu Tiexing saw Zhu Cijiong coming, and hurriedly brought several masters over to salute:

"Weichen see Your Majesty!"

Seeing that it was so late, and the masters were still working overtime, Zhu Cijiong smiled at the corner of his mouth: "Everyone, please get up, these days, it's hard work!" ”

"Don't dare! Can't! ”

A group of masters hurriedly greeted.

"Wu Dazhui, how much can the output reach now?"

Wu Tiexing stretched out three fingers: "Your Majesty, now we can build thirty Franc machines every day, and as for the red-coated cannons, we can build one every two days." ”

Zhu Cijiong nodded, this output is enough.

"Are there any difficulties?"

Wu Tiexing thought for a while: "The difficulty is nothing, but there is one thing that Weichen doesn't know how to solve." ”

"Oh?"

Zhu Cijiong was surprised: "What is the matter, so that the artillery workshop can't solve it?" ”

You must know that the current artillery workshop has gathered hundreds of masters!

"It's still a matter of the gun mount."

Wu Tiexing smiled bitterly: "Your Majesty, this artillery is placed on the car, so it is naturally easy to travel." It's just that in this way, the gun carriage has to be very heavy, because the recoil of the gun is too great......"

"If we take care of lightness and make it thin, this gun carriage will easily collapse after releasing a few shots."

"If we thicken the gun carriage, the weight will be too much, the gun carriage will be bulky, and it will be difficult to transport......"

The Franc machine is okay, the cannon with the gun carriage is only six or seven hundred catties, and even the small Franc machine weighs only two or three hundred catties.

However, the red-coated cannon is different!

That thing weighs thousands of catties of artillery alone, and it can even cast nearly 10,000 catties of cannons.

Even the lightest of the cannons in red is very difficult to transport!

……

So that's what happened!

Zhu Cijiong smiled dumbly.

In the vehicles of this era, the body was placed directly on the axle.

Therefore, when firing the gun, the gun carriage is equivalent to bearing all the recoil.

Historically, when solving this problem, the method of shock absorption and brake was adopted in parallel.

Of course, the brake can't be made now, but the shock absorption is possible.

"I want you to work together with the Musket Workshop to study this problem."

Zhu Cijiong picked up a thin iron sheet casually, bent it into a steel plate to absorb shock, he pressed it lightly with his hand, and the thin iron sheet was deformed, but when he let go, it returned to its original state:

"You see, if you make the axle junction like this, the recoil will be canceled out by the spring when the gun is fired, so you can reduce the weight of the car."

Fan Jiazhu frowned: "Your Majesty, this method is good, but the elasticity of this iron piece is not good!" After a few bends, it loses its elasticity. ”

"Isn't that the same as building a soft sword!" A white-haired craftsman said, "If it is made of steel, it will be competent, but if the steel continues to be beaten, it will easily break......

Zhu Cijiong chuckled: "No, as long as you use the finished steel sheet, bend and shape it after it is red." ”

The white-haired craftsman shook his head: "Your Majesty doesn't know, if steel is overheated, it will turn into iron and lose its elasticity. ”
