Chapter 448

They walked along the hard road of Qingzhou City to the workshop area. Along the way, rod was surrounded like an animal.

With rod, they arrive at the workshop area, where the craftsmen are building a new workshop.

Next to the building being built, there is a pile of cement, sand and stones. Xiao Ming brings rod over. The craftsmen immediately stop their work and stand aside respectfully. Xiao Ming grabs a handful of cement and says to rod, "this is cement, mixed with water, sand and stones. After three or four days, the hardness will be the same as the road just now."

Rod looked at something like flour. He couldn't believe it. He looked at some of the craftsmen who were mixing concrete. "The road is so hard. Why do you rely on it?"

"Yes, don't underestimate it. Don't think that only you in Europe can have such magical things." With that, Xiao Ming went to the concrete mixing place and picked up a few hard blocks to return to rod. "You can have a try. This is the cement block that hasn't set for a long time. It's not hard enough, but it's hard to cut the sword after a few days."

Rod took it and used a lot of effort to crush the cement into powder. He was shocked.

He once thought that Dayu was just a backward civilization. Even if the king of Qi had flint guns and artillery, he just learned from Europe, but now everything is wrong.

It's incredible to have something here that Europe doesn't have.

The cement is just a small episode. Xiao Ming knows that what rod wants to see is not cement, which is the livelihood of the people, so he takes rod to the Qingzhou army.

After seeing the equipment and training of Qingzhou army again, rod was not good at all. His body was shaking when he walked in the barracks, and Lufei and others seemed to work hard to frighten rod.

After that, Xiao Ming took rod to the equipment department to see the military foundation of Qingzhou. After seeing these things, rod was like a defeated rooster.

"Ambassador Rhode, how about our king's Qingzhou?" After a few places, Xiao Ming asked with a smile.

Rod's smile was a little reluctant, he said: "Your Highness's strength is beyond my expectation. When I go back, I will talk to count Clare about Ryukyu Island."

Xiao Ming nodded. From rod's expression, he knew that rod was shocked.

The reason why he took rod to visit these places was to subdue the soldiers without fighting. Now the attitude of the Dutch has softened. To scare them again, Ryukyu said that they can't take it back without fighting.

It seemed that he was stimulated. Rod had no plan to stay in Qingzhou. He was gloomy all the way and didn't know what he was thinking.

Seeing this, Xiao Ming said, "ambassador rod, it's time to have dinner soon. It's better to have dinner in the palace."

"No, I think I have to go back."

"All right." Xiao Ming said that he did not want to entertain the arrogant Dutch.

Rod declined the invitation, and on the same day he went to Dengzhou under the protection of the guards, ready to go back to Ryukyu.

Seeing rod leave, Xiao Ming turns to go back. At this time, he sees Liang Yubin coming on horseback.

In front of Xiao Ming, Liang Yubin said excitedly, "Your Highness, Lin Wentao has got the pump steam engine out."

"Pumping steam engine?" Xiao Ming was stunned when he heard that it was not a new Komen steam engine, was it?

Thinking of this, he immediately went to the school of Bowen.

When he arrived at Bowen college, Liang Yubin directly led Xiao Ming to the laboratory of physics college.

At this time, the laboratory was surrounded by college students, and everyone was paying attention to the new things Lin Wentao had made.

"Not bad!"

The steam engine in front of Xiao Ming is just a simple model of steam engine, not a full-scale one.

This steam engine is composed of two parts, one is a conical boiler, which belongs to the steam engine, and the other part is connected by the connecting rod, which is the pumping part. At this time, the connecting rod continuously moves back and forth to let the other half pump up the water in the tank.

The successful development of the steam engine inspired all the students in the college. Lin Wentao was full of tears. After the last explosion, he finally developed the newcomer steam engine.

Although this kind of steam engine can only be used to lift water, it is not a real duplex steam engine, but it is the progress of Qingzhou and physics college.

"Wentao, you've made a great contribution." Xiao Ming patted Du Zhiping on the shoulder.

So far, the difficulty of this steam engine is undoubtedly the biggest. After all, this is a direct jump from poverty to the complex equipment of steam engine.

Lin Wentao not only had to solve the problem of steam, but also the problem of connecting rod. He said, "come on, what kind of reward do you want?"

Lin Wentao then said: "Your Highness, I don't want any reward. This newcomer steam engine is just the most basic steam engine. Please reward me when I make the duplex steam engine."

Xiao Ming nodded. He was very satisfied. Now Lin Wentao has changed from studying steam engine for his title to loving science. He said, "OK, I promise you."Although Lin Wentao didn't want anything this time, Xiao Ming rewarded him with 1000 liang of silver. He wanted other students to see that everything was possible only if he was willing to work hard.

After the successful development of the basic model of newcomer steam engine, Xiao Ming immediately asked Lin Wentao to study the construction of newcomer steam lift for the mine. In terms of the current number of mines, Xiao Ming needs more than 30 pumps at a time, so that the mine can be further excavated.

After all, many minerals in his fiefdom belong to deep mines. Once the mine cave is flooded, it can't be constructed. Now with the advent of newcomer steam engine, he can improve the efficiency of minerals many times.

However, at this time, the newcomer steam engine is only the most primitive steam engine, and it consumes a lot of coal, so it is only suitable for use in the mine.

The new year is coming soon. Xiao Ming didn't expect that Bowen college could give him such a surprise at this time.

He is going to put the construction of newcomer steam engine on the agenda, and let the equipment department cooperate with Lin Wentao to build a real steam engine. After all, Lin Wentao is only experimenting with his small model, and the real restoration still needs a lot of craftsmen.

After praising Lin Wentao and others, Xiao Ming excitedly returned to the palace. Although the newcomer steam engine was the simplest one, it was through continuous improvement that the later steam engine got the later watt steam engine.

Now Lin Wentao has found the way to the steam engine. He believes that it will not be long before he can develop a real steam engine.
