Zhou Heng nodded quickly and stared at the emperor's feet. Why is this old emperor so shameless? He even asked?

Then Zhou Hengxin made a fuss and said quickly:

"Your Majesty is wise. This thing is called a condom. When the yin and yang between men and women are harmonious, wearing it can naturally avoid conception and enjoy the love between men and women normally. Of course, it can also 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 was confused and didn't understand what Zhou Heng was saying at all, but looking at the emperor's meaning, he already understood and was very interested.

"Why can this thing avoid conception?"

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

"It seems that I should find a marriage for Yun Mo. I will naturally understand it if I have a wife."

Zhu Yunmo was startled and waved his hand quickly.

"Uncle Huang, don't scare me. Yun Mo is still young. Let's talk about getting married two years later. The rubber tree matter in front of me and the temporary hospital matter are all imminent. The workshops in Beishan also need to be expanded, and the training of the medical school is even more intense. How can I have time to think about these things now?"

The old emperor looked at Zhu Yunmo with an anxious look on his face and nodded slightly. Unexpectedly, the most ignorant boy could pretend to be so many things in his heart. It is true that many things are imminent now. Although Zhou Heng did not explain the things produced by this rubber tree in detail.

Obviously, it has a more important purpose, and no one has made it before, especially these rubber trees are still beyond the reach of Fujian Beijing, so it is indeed necessary to arrange them well.

"Well, it makes sense, but you have to start screening your marriage, I will pay attention to it."

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

"Your Majesty has one of the most important things here, of course, our vision. If we can succeed, defense against the border and reconnaissance can be said to be an unprecedented development."

The emperor was instantly attracted by Zhou Heng's words. Although Daliang was vast, the manpower and material resources spent on guarding the border were really a big deal. His words directly touched the old emperor's heart.

His eyes immediately fell on Zhou Heng's hand. At this moment, he was holding an oval-shaped black ball with a small basket underneath, and several threads were tied to the bottom of the ball. After watching for a long time, he couldn't see what was going on.

"What is this?"

Zhou Heng smiled and raised the ball in his hand.

He had to convince the emperor to invest and send troops, otherwise the rubber would not be able to be used at all and might be subject to others.

After all, the Fujian governor was Wen Changming, who was the third brother of Wen Shangshu. Not to mention that he was irreconcilable with the Wen family now, it would be an irreconcilable relationship. If he had a pair of shoes during this period, it would be enough to drink a pot by himself.

"Please look, your Majesty, we have made a model, this is a hollow rubber flying ball, the actual size can be three or four meters, it can withstand high temperatures, and the weight is very light. At the opening below, we hung the basket.

After igniting this with fuel, the air can float when it is heated. The ball can swing the fan blades through this shaking handle, and the direction can be changed at any time. The basket below can be carried by four people, and tiny oil bottles or some other things can be placed inside. The personnel can also be masters who can walk through the sun for hundreds of steps.

If you use every move of ten miles of this ground to be in front of you, even if you float to the enemy to conduct reconnaissance, harassment and assassination are not a problem. We are condescending, and even if the opponent wants to destroy the ball, it will be extremely difficult."

The old emperor was stunned, took the ball over, held it up and looked carefully, he had never seen such a novel thing before.

However, Zhou Heng's explanation is so tempting, it is simply tailor-made for the shortcomings of the beam.

He looked up at Zhou Heng, with doubt in his eyes and a trace of murderous aura, yes murderous aura.

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

"How did you think of this thing? As far as I know, you don't seem to have been to the border, and you have never seen the battlefield. How can you understand it so thoroughly?"

Zhou Heng looked at the old emperor calmly. He knew that today would make the emperor suspicious. After all, a doctor knew so many things, which was enough to make people wary.

Especially designing border defense layouts and some things to defend against enemies, these are all taboos among taboos.

Zhou Heng smiled, quickly bowed to the old emperor and said:

"Didn't Your Majesty ask me to treat Ningyuan Hou and a group of veteran generals? I heard them talk about when the casualties were the most serious, what was the most panicked in the border guards, and the offense and defense that were the most injured.

After understanding these things, when we were making rubber products, we accidentally discovered the beauty of this rubber ball. Look here."

Zhou Heng bent over and found a balloon in the box, filled the balloon with a hand-held pump, and then tied the end 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 used a few raw materials to waste them. At that time, we also used the rubber elasticity to fill it with gas. Unexpectedly, the balloon floated up instantly.

Then I thought of the principle of Kongming lantern and designed this flying ball, but all of this is in the imagination. If it is made, some other things need to be added to the inner layer of the latex to make rubber that is not afraid of heat. Only such a flying ball can be of great use.”

The old emperor suddenly realized and glanced at the condom next to him. It was indeed very similar to this balloon. At this moment, he firmly believed in Zhou Heng's words. After all, what a doctor could think of was to cure diseases and save people.

As for this rubber ball, it is probably because these veteran generals complained a lot that this idea came up, but this person is really extremely intelligent.

"Zhou Aiqing said it very well. Although this idea is bolder, it is not impossible. I will order you to secretly develop this thing."

Zhou Heng saluted his politely and said:

"I will follow the order and will definitely develop flying balls well. However, this rubber plantation is far away in Fujian. I am just a doctor. I am really a little helpless. Although this is a business, it is related to the border defense and the country. Your Majesty, you and us, and we..."

Seeing that Zhou Heng was hesitant, Zhu Yunmo hurriedly got closer.

"Just say what you have any ideas. Uncle Huang is a far-sighted and visionary wise king. How can we cooperate with this business? It does not go through the Ministry of War or the previous dynasty, but just acts as a business. In this way, no one studies the purpose of this thing?

You don’t have to pay money or personnel. You just need to coordinate a team to protect the rubber plantation. As for transportation, someone needs to escort it. All we can do is organize a team of cars and horses. It is still a problem to escort it. Who knows what will happen on the way? If it is cut off and falls into the hands of those who are interested..."

The emperor stared at the two of them, his eyes becoming deeper.

Obviously, the two of them had already discussed it before coming. They thought about it so clearly that the fewer people knew about it, the better.

If they really put it in the Ministry of War, they would save money even if they wanted the treasury to pay.

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

"I will consider it. It's getting late, so you can go back."

Zhu Yunmo was stunned. He didn't expect that he would still think about such conditions, but whether he agreed or disagree, he had released the people, and the samples were prepared, and he didn't need to invest money. Why did he think about it?

Zhou Heng knew what Zhu Yunmo was thinking without looking up, so he rushed to say:

"I'm going to leave."

Zhu Yunmo looked unhappy, but Zhou Heng said he could not stay alone even if he left, so he bowed slightly.

The two withdrew from the Palace of Heart, and Fang Jizhong looked at the two of them with a look of defense, fearing that they would make any more trouble, so he came over with a smile on his face.

"The Crown Prince Zhou Yuan, the judge, Fang Hua is already waiting here, please. Please, two of you."

Zhu Yunmo snorted and followed Zhou Heng into the car.

Seeing that the car had left, Fang Jizhong quickly entered the Palace of Harmony and saw the emperor looking at the chessboard, he walked over quickly.

"His Majesty?"

The emperor looked up at Fang Jizhong.

"Leave?"

"Let's go, your Majesty is going to flip the sign tonight?"

The emperor shook his head.

"I have to think about it, how did Zhou Heng know so many things that others don't understand?"

Fang Jizhong was stunned.

"This old slave really doesn't know. His life experience has been investigated clearly. Perhaps he has lost his memory and his mind is different from that of ordinary people, right?"

The emperor looked up at Fang Jizhong and sighed.

"Maybe, I remember that in the news you sent back, he once said when he enlightened General Cao that a small doctor treats diseases, a Chinese medicine doctor, a great doctor treats the country, maybe he has other ambitions."
