How much is the offer!

Although he could design better ball bearings, Zhu Mingzhong is more willing to buy the patent for this roller bearing that still seems a bit original, because it represents the technological progress of the Ming Dynasty. It was an invention without his intervention, and such creation should naturally be encouraged.

Moreover, Zhu Mingzhong knew what kind of changes this roller bearing would bring to the carriage, and he could realize its value. The advent of roller bearings will undoubtedly bring qualitative changes to the transportation industry of the Ming Dynasty. The carriage will become faster and have a larger load capacity. Of course, the railway will also benefit from it. With the same pull-up force, a "train" has more composition and a larger load capacity.

At this time, Zhu Mingzhong seemed to have seen the new carriage galloping across the country, and saw the scene of the new train leading to the Western Regions. It will bring countless wealth to merchants, and will also bring him wealth, and more importantly, it will bring a small revolution to traditional transportation.

"You, you want to buy it?"

Dai Zi looked at the person in front of him in surprise.

"Are you sure?"

"Of course, ten thousand... ten thousand taels, how about it?"

What!

"Ten thousand taels!"

Dai Zi shouted in surprise.

"You're going to spend 15,000 taels to buy it?"

He never thought that his invention would be worth so much money. For him, it would have been enough to sell it, but the man in front of him was willing to buy the bearing for 15,000 taels.

"That's right, it's just 15,000 taels!"

"Just this little thing?"

As soon as Zhu Mingzhong finished speaking, the merchants who had been attracted by Dai Zi's shouts all looked at the copper bearing in surprise, and could not believe that it was worth so much money.

"Ten fifteen thousand taels, beloved, what's so valuable!"

“It’s used in the carriage!”

"The carriages are enough for hundreds of carriages!

"No, how many carriages have to be sold to pay for the money?"

Everyone's words made Zai Zi blush and said.

"First, sir, this is not worth so much?"

"Why isn't it worth it?"

Zhu Mingzhong shook his head and watched Dai Zi take the initiative to explain to him.

"With this bearing, a carriage with two pulls can be turned into a single pull, and its speed does not decrease and its load capacity does not decrease. As long as a few bearings are replaced, there will be less horses or more horses. Why is such a good thing not worth the price?"

Zhu Mingzhong did not say its usefulness, but just told the public directly that using it can reduce the use of horses, which is enough. After all, the cost of raising horses is not low. If you use one less horse, the money saved is not a decimal.

"Sir, you mean, this thing can save a few horses..."

Just when a businessman was interested, Zhu Mingzhong had already picked up the bearing and turned it gently. When the rotational sound it made was rotating in his hand, Zhu Mingzhong said with a smile.

“Can the bearing shells be rotated so easily?”

Of course not!

Even the bearing shell that had just dripped oil cannot rotate like it. If I didn't understand it before, some merchants have realized the wealth it contains, and almost immediately someone asked tentatively.

"This young master, this is your invention. The gentleman just now offered 15,000 taels, and I offered 16,000 taels..."

"I'll pay 17,000 taels!"

Someone actually increased the price!

In an instant, the museum became lively and everyone nearby was attracted. After realizing the wealth contained in this book-sized bearing, people began to add up prices. After all, there were tens of thousands of carriages in the Ming Dynasty, and a business of more than tens or even hundreds of thousands of bearings a year. What's wrong with raising prices...?

"Twenty thousand!"

Amid the crowd's price increase, Dai Zi, who had been shocked by these enthusiasm, saw the gentleman who had been standing aside with a smile on his face, thought that it was his keen eye that made everyone bear it.

"Everyone, listen to me, I have transferred the patent to this gentleman. If you want to, you might as well discuss it with this gentleman."

He directly pushed out the huge sum of 5,000 taels.

Is it heartache? Even Dai Zi, who went out to the official family, really made him feel heartache for a while, but he didn't regret it. Even when he thought that he would immediately have a large sum of money to make money and could continue to engage in research, he turned red at this moment.

For him, the money was only used for research.

Dai Zi's refusal disappointed everyone, and praised his character. After all, people who can choose righteousness at the same time will always be admired. In addition, everyone has even begun to think about it automatically. Some are wondering whether they have to buy it from this person at a high price, while others are wondering whether they can improve this kind of bearing. After all, the patent law also has loopholes.

Just as the adults were thinking about it, He Jia, He Yu, Yu Xin, Yuting, and Yuting were still playing in the museum. The Ming Dynasty now does not need to worry about flower shooters and plundering children, because there are cruel laws to punish them. As long as you catch them, the light ones are beheaded, and the worst ones are Lingchi, and the three tribes are exiled. Even if the buyer is punished, it will be severely punished. Not only will the whole family be sentenced to ten years in prison, but the Lian tribes are even exiled. Because of this, the plundering of children has become a high-risk industry that is not worth the loss in the Ming Dynasty. Occasionally, the buyer's relatives and neighbors are often proactively reported to the buyer.

This kind of zodiac seems rough, but it is very effective. Almost since the second year of Xingqian, there have been no cases of plundering children. Of course, He Jia, He Yu, Yu Xin, Yuting and others don’t need to worry about this. After all, when they looked left and touched the right, there were always people following them not far behind.

For these children, everything here seems to be very interesting, but it is often not very fun. After all, there is nothing for children to play with. Just when they are bored, Zhu Hejia suddenly saw something. It was an egg-sized gray-white ball. After obtaining the consent of others, he picked up the ball and felt it was hard, but if he pinched it hard, he could feel its elasticity.

“Is it table tennis?”

Zhu Heyu also stared at the ball curiously and said. Table tennis was an entertainment activity brought to this era by Zhu Mingzhong, but its ball was made of cork.

"Table tennis is made of cork. This is not cork."

Zhu Hejia, who was a little curious about this little ball, suddenly threw the small ball in his hand to the ground with a whim. The moment the ball hit the ground, it suddenly bounced away for several meters.

“It’s so high!”

Now the children were having fun. Unfortunately, the things here were not for them to play with. Just as they were running and recovering the flying ball, the students guarding the glass cabinet over there were smiling and trying to take back the ball.

"How much does this cost?"

Regarding this small ball that could pop up a few quick heights, Zhu Hejia naturally had the intention to take it as existing, so he immediately started to take it as existing.

"Yes, yes, how much does one cost? How many of them are there here? Are you selling them to us? I'll do it..."

When Zhu Heyu calculated how many brothers and sisters could play this ball, the students there refused without hesitation.

"The young master was joking. The things here are exhibits, not for sale. These exhibits are collected from various countries..."

At this moment, Zhu Mingzhong, who had just finished the procedures, had already come over. When the children saw him coming, they immediately shouted.

"Dad, dad, come and take a look. The small ball here is interesting. It can bounce a few feet high at once!"

As the children were pulling, they came to the glass cabinet and saw the ball in the cabinet, and asked with a smile.

"This is from America!"

Although its appearance is different from that in imagined rubber, Zhu Mingzhong still recognized it as rubber. Nothing can have such elasticity unless it is rubber.

"This gentleman is very knowledgeable. This is brought by Mr. Alfonso from the Americas in the school. It is very elastic. The local native football game uses it to make the balls, and they also apply some thick white liquid on their clothes. Wearing this kind of clothes on rainy days is not rainy. We found that this material can effectively wipe away the traces left by the pencil..."

After listening to the students' explanation, the Zhu Hejia brothers said with great interest.

"Dad, tell the master and give us these balls."

The master was naturally Zhu Zhiyu, the mountain captain of Qinghe Academy. The children's words made the student look at the person in front of him in surprise. He was the student of the mountain captain? But even if the student of the mountain captain, I am afraid the mountain captain would not necessarily give them these balls, after all, they are too precious.

"This is……"

Suddenly, Zhu Mingzhong's attention was focused on a glass box next to the ball. The box contained more than a dozen seeds the size of quail eggs. It could be recognized from the pattern on it. These were rubber seeds.

"This is its seed!"

At this time, Zhu Mingzhong's tone seemed a little suffocated. When the Navigation Association began to sail to America, he had instructed them to collect local species, especially the cinchona and the seeds of rubber trees, but he never expected that he would see rubber trees here.

"Yes, sir, this was collected by Mr. Alfonso in the academy. He had preached in the Americas for many years. As a botanist, he collected a lot of seeds during his time in the Americas. However, this kind of tree is not suitable for seeds in Qinghe..."

Of course it is not suitable, this is a tropical crop!

"Are there only a dozen seeds? Are there any more?"

Zhu Ming asked immediately.

"Professor Alfonso may have some more there."
