Zhou Heng nodded hurriedly and stared at the emperor's feet, why is this old emperor so shameless, knowing that he still asks?

Immediately, Zhou Hengxin turned his heart and said quickly:

"Your Majesty is wise, this thing is called a condom, when the yin and yang between men and women are harmonized, wearing it will naturally avoid conception, and you can also enjoy the love of men and women normally, of course, it can be improved, this thickness can be ...... A little thinner, and the surface can be made with particles or threads according to different molds......"

Zhu Yunmo looked confused, he didn't understand what Zhou Heng was talking about, but looking at what the emperor meant, he already understood and was very interested.

"Why does this thing prevent conception?"

The old emperor raised his eyes, stared at Zhu Yunmo for a few moments, and then raised his head and laughed.

"It seems that I should find a family affair for Yunmo, and I naturally understand this with my wife."

Zhu Yunmo was startled and hurriedly waved his hand.

"Uncle Huang, don't scare me, Yunmo is still young, let's talk about getting married two years later, the matter of the rubber tree in front of me, as well as the matter of the cabin hospital, are imminent, the workshop in Beishan also needs to be expanded, and the training of the medical school is in full swing, where is the time to think about this now."

The old emperor looked at Zhu Yunmo, who was eager, and bowed slightly, he didn't expect that the most unlearned kid could pretend to be so many things in his heart, it is true that many things are imminent now, the things produced by this rubber tree, although Zhou Heng did not elaborate.

Obviously, there are more important uses, and no one has made them before, especially these rubber trees are still out of reach in the capital of Fujian, so they really need to be arranged.

"Well, there is some truth to that, but your marriage will also start to be screened, and I will pay attention to it."

Zhu Yunmo looked bitter and wanted to explain something, Zhou Heng pulled the corner of his clothes behind him, and then stepped forward and took the bottom thing in the box and said:

"Your Majesty, there is another most important thing here, of course, our assumptions, if successful, the defense of the frontier, as well as reconnaissance, can be said to be an unprecedented development."

The emperor was instantly attracted by Zhou Heng's words, although the area of Daliang is vast, the manpower and material resources spent on guarding the frontier land are really head-wrenching, and his words directly pierced the heart of the old emperor.

His eyes immediately fell on Zhou Heng's hand, at this moment he was holding a black ball similar to an oval, with a small basket underneath, and several threads tied to the bottom of the ball, and he didn't see the reason for looking at it for a long time.

"What is this?"

Zhou Heng smiled and raised the ball in his hand in the air.

He had to persuade the emperor to join the stock and send troops, otherwise the rubber himself would not be able to use it at all, and he might be subject to others.

After all, the political envoy of Fujian is Wen Changming, who is the third brother of Wen Shangshu, not to mention that he is not going to die with the Wen family now, it is also an irreconcilable relationship, if a pair of small shoes comes down during this period, it is enough to drink a pot of himself.

"Your Majesty, please see, we have made a model, this is a hollow rubber flying ball, the actual size can be three or four zhang in size, can withstand high temperatures, the weight is very light, in the opening below, we hang the basket.

After this is ignited with fuel, the ball can fly when the air is heated, and the fan blades can be changed at any time through this rocking handle, and the basket below can take four people, and there can also be a fire oil bottle or some other things in it, and the personnel can also be a master of a hundred steps.

If we were to patrol the border, we would be able to see everything we could do within a radius of ten miles on the ground, even if we drifted across from the enemy to investigate, harass, and assassinate, we were condescending, and it would be extremely difficult for the other side to destroy the ball. ”

The old emperor was stunned, took the ball, raised it and looked at it carefully, he had never seen such a novel thing.

However, Zhou Heng's explanation is too tempting, this is simply tailored for the shortcomings of the beam.

He raised his eyes to look at Zhou Heng, there was doubt in his eyes, and there was a hint of murderous aura, yes, murderous aura.

For a moment, the old emperor really wanted to kill the kid in front of him, and he seemed to be able to peek into the secrets of his heart.

"How did you come up with this, as far as I know, you don't seem to have been to the frontier, let alone seen the battlefield, how can you know so much?"

Zhou Heng looked at the old emperor indifferently, he knew that today would definitely make the emperor suspicious, after all, a doctor knew so many things, which in itself was enough to make people vigilant.

In particular, the design of the border defense layout, as well as some things to defend against the enemy, these are all taboos among taboos.

Zhou Heng smiled, and hurriedly saluted the old emperor and said:

"Didn't Your Majesty ask the ministers to give Ning Yuanhou and a group of old generals to diagnose and treat, I heard them talk about when the casualties were the greatest, what was the most panicked by the border guards, and the most injured were attacking or defending.

Knowing this, when we were making rubber products, we stumbled upon the beauty of this rubber ball, you see here. ”

Zhou Heng leaned over to find a balloon inside the box, filled the balloon with a hand-held pump, and then tied the tail with a rope.

Pulling the rope, the balloon gradually floated up, and Zhou Heng pulled the rope and handed it to the emperor.

"Your Majesty, when we were making condoms, we wasted a few raw materials, and at that time it was also to test the elasticity of rubber, so we filled it with gas, but I didn't expect the balloon to float up instantly.

Then Chen thought of the principle of Kong Ming lantern and designed this flying ball, but all this is in the imagination, if it is made, it is necessary to add some other things to add to the inner layer of latex, specifically to make a rubber that is not afraid of heat, so that the flying ball is useful. ”

The old emperor came to his senses, glanced at the condom next to him, it was indeed very similar to this balloon, and he firmly believed in Zhou Heng's words at this moment, after all, what a doctor could think of was to cure the disease and save people.

As for this rubber ball, it is estimated that these old generals complained a lot before they came up with such an idea, but this person is really smart.

"Zhou Aiqing said very much, although this idea is bold, it is not impossible, I will order you to secretly develop this thing."

Zhou Heng solemnly saluted and said:

"The minister obeys the order, and will develop the flying ball well, but this rubber plantation is far away in Fujian, the minister is just a doctor, and he is really a little powerless, although this is a business, it is related to the major affairs of the border society, Your Majesty or you and us, and we ......"

Zhu Yunmo saw that Zhou Heng was a little hesitant, and hurried closer.

"If you have any ideas, just say it, Uncle Huang is a far-sighted and far-sighted gentleman, Uncle Huang, how about we cooperate in this business? It doesn't go through the military department, it doesn't go through the previous dynasty, it just does it as a business, so no one studies the use of this thing?

You don't need to pay for the money, and you don't need to go out of the personnel, just coordinate a team to protect the rubber plantation, as for transportation, this also needs to be escorted, what we can do is only to organize a team of carriages and horses, but the escort is still a problem, thousands of miles away, who knows what will happen on the way, in case it is intercepted and falls into the hands of someone with a heart......"

The Emperor stared at the two of them, his eyes darkening.

Obviously, these two people have already discussed before coming, and they are thinking about each one so clearly, and it is true that the fewer people who know about it at this time, the better.

If they really put money into the military department, they want to save some money from the internal funds.

The emperor had already gone through this matter several times in his mind, and no matter how he thought about it, he felt that it was indeed a good thing, but seeing the two of them singing and harmonizing, the old emperor coughed.

"I'll think about it, it's not early, so let's go back."

Zhu Yunmo was stunned, he didn't expect him to think about such conditions, but whether he agreed or disagreed, everyone was released, the samples were ready, and he didn't need to invest the money, how could he think about it?

Zhou Heng didn't need to look up to know what Zhu Yunmo was thinking, so he hurriedly said:

"Wechen retired."

Zhu Yunmo looked unhappy, but Zhou Heng said that he couldn't stay alone, and he also bowed slightly.

The two of them withdrew from the Heart Cultivation Palace, and Fang Jizhong looked at the two of them with a defensive face, lest they make any more moths, so he came up with a smile on his face.

"Shizi Zhou's court judged, Fang Hua is already waiting here here, two of you, please."

Zhu Yunmo snorted and followed Zhou Heng into the car.

Fang Jizhong saw that the car was gone, so he quickly entered the Heart Cultivation Palace, and saw the emperor looking at the chessboard in a daze.

"Your Majesty?"

The emperor raised his eyes to look at Fang Jizhong.

"Gone?"

"Let's go, Your Majesty is going to turn over the cards tonight?"

The Emperor shook his head.

"I want to think about it, how did you say that Zhou Heng knew so many things that others didn't understand?"

Fang Jizhong was stunned.

"This old slave really doesn't know, his life history has been investigated clearly, maybe he has lost his memory, and his brain is different from ordinary people, right?"

The emperor raised his eyes to look at Fang Jizhong and sighed.

"Perhaps, I remember that in the news you sent back, he once enlightened General Cao and said that a small doctor heals the sick, a Chinese medicine heals people, and a big doctor heals the country, maybe he has other ambitions."
