The world is in a great way, and those who follow it will prosper, and those who go against it will perish.

Gao Huan knew that the Dagan Empire had a fatal flaw. Now because he was in charge of the government, this flaw was not obvious. It can even be said to be the advantage of the Gan Dynasty. It is hard to say after it can be said.

This flaw is that because the imperial system led to the development of the empire, especially the development of science and technology, relying very much on an enlightened and wise monarch.

If the heirs of the empire lack understanding of science and technology, have no curiosity about science, and are not interested in these, the political system that has been in charge of the dynasty will probably soon become rigid, and science and technology will progress slowly, or even stop moving forward.

Now, as the emperor, Gao Huan, because of his persistence, Ganchao's technology has developed rapidly, but the later monarchs are not wise and the brain of the empire does not work, which will inevitably affect the development of Ganchao.

After all, the system of the empire requires a wise ruler to leverage the advantages of centralized autocracy. Once the heirs are not good, the empire will decline.

Gao Huan is now in his prime. In order to better promote his will, autocracy must be carried out. As for how to determine in the future, the heirs are all wise rulers and how to reform, Gao Huan has not yet been in the mood to think about it.

Gao Huan smiled and said to Song Yingxing: "Today I have something to ask you, Mr. I hope you can give me some good things to you for me and tell me the achievements of the Ministry of Works, so that they can become interested in science!"

Song Yingxing understood Gao Huan's meaning. The princes were the future heirs of the empire. Their understanding of science and technology is beneficial to the development of various science and technology in the Ministry of Industry and the future.

If the prince only knew the Four Books and Five Classics, he learned all the liberal arts and did not understand technology, and after inheriting the empire, he would naturally not pay attention to technology, and would not use technology as a means to solve national problems, but would go to the doctrine of the saints and find ways to govern the country.

"I understand!" Song Yingxing immediately saluted and said sideways: "In this way, Your Majesty and Your Highness, please come with your followers!"

At that moment, Song Yingxing led his group into the Ministry of Works and took several princes to visit, visiting various new matters such as weapons manufacturing, civil technology, etc.

The children were curious and immediately opened a new door.

When Gao Huan explained the principles of weapons in Song Yingxing, he asked Gao Hu how these muskets and cannons were compared to swords. He taught him how to make scientific and technological progress and weapons innovation. If he did not master advanced military technology, he would be passively beaten once he was surpassed by the enemy.

Among the many princes, only the crown prince Gao Hu was interested in weapons, and the rest of the children were attracted by other things that were dazzling.

The Ministry of Industry and Technology is very big and needs to educate children, but it will not be effective in one day.

Song Yingxing's speech was vivid and interesting. After taking the children to do one or two optical experiments, he brought Gao Huan and his party to the topic today.

Gao Huan came to the yard and saw the huge creature he saw last time, which was obviously a circle smaller than when he saw it last time, and he couldn't help but feel happy.

However, the children were still shocked when they saw this dark, huge and ugly thing.

"Father, what is this?" Gao Hu couldn't help asking.

Gao Huan smiled and said, "Let Mr. Song explain it to you!"

Song Yingxing said: "Your Highness, this is a steam locomotive, it is an amazing invention!"

The children naturally couldn't see the reason and didn't understand its meaning. Gao Huan asked excitedly: "Where are the problem of airtightness solved?"

Song Yingxing said: "After Your Majesty last described what rubber is, I wonder if my country is vast and rich in resources. Will there be similar items? Later, I found a kind of Eucommia rubber, made into rubber rings and rubber pads, brushed with oil and put them on the piston. The airtightness has indeed improved greatly on the machine."

After hearing this, Gao Huan immediately said, "Open it and try it!"

When Song Yingxing heard the words, he waved his hand and ordered, "Burn the boiler!"

The craftsmen lit the fire and sent shovels of coal into it. This time, the steam engine did not leak everywhere from the beginning.

Soon, amid the sharp whistle, the steam piston began to move, and every time it exhaled the usual white air, which made the little princes feel scared.

Gao Huan was overjoyed when he saw this and exclaimed: "Okay! This is a huge progress!"

Gao Yuncheng, who was standing beside him, asked with his little head on his face: "Father, this strange thing has such a terrible voice. Is it useful for governing the country?"

Gao Huan was slightly stunned, but he didn't expect him to ask such a question.

Song Yingxing, who was standing beside him, said: "Second Your Highness, take a look again, and then what do you think it is useful!"

After saying that, Song Yingxing winked at the craftsmen, and the craftsman pulled down a iron rod, the steam locomotive's reciprocating connecting rod, immediately put on the gears, and transmitted the force through several sets of gears, driving the wheels and slowly moving on the laid rails.

When many princes saw this scene, they exclaimed, "Father, it's moving, it's moving..."

In the children's perception, only humans and animals can move. Now, when they see steam locomotives moving slowly on the rails, they are all stunned, and some are so scared that they hide behind Gao Huan.

This made Gao Huan feel that he was wrong to bring them here today. If he left a shadow on them, it would be a mistake.

Seeing this, Song Yingxing quickly asked the craftsmen to stop the motorcycle that was moving, and the children immediately calmed down.

In order to eliminate their fear, Gao Huan took them to the motorcycle and observed them closely. The children were curious and quickly eliminated their fear.

At this time, Gao Huan looked at Gao Yuncheng and smiled and said, "Emperor, do you think this steam locomotive is useful for governing the country now?"

Gao Huan was surprised that such a young child could think of governing the country, but after all, he was a child, and his cognitive ability was revealed, not born to know it like him, so Gao Yuncheng had a red face and couldn't tell why, just said, "Father, this thing is really magical."

Gao Huan smiled slightly and asked Yang Yan to take several princes to the cart dragged behind the motorcycle, and asked the craftsmen to start the steam locomotive again.

This time the car moved, the children were no longer afraid, but instead found it very fun and laughed happily.

Gao Huan and Song Yingxing stood aside and continued to have a conversation, "My dear, a section of the railway in Shanxi has been laid. Can the Ministry of Industry and Technology build one and transport it over?"

Song Yingxing politely said, "Your Majesty, I have something that requires your Majesty's approval."

Gao Huan waved, "You said."

"Your Majesty, the steam locomotive prototype has been made, but in order to be truly practical, many places need improvement and testing. For example, the life of the steam engine and the aging of the rubber ring, the Ministry of Industry and Engineering has no data. Therefore, I hope that the court can build a steam locomotive workshop in Shanxi to conduct testing and improvement of the steam locomotive nearby." Song Yingxing said in a deep voice.

Gao Huan nodded slightly. After the things were made, they really needed to go through repeated tests before they could be put into practical use. Otherwise, if a major accident occurred, it would be detrimental to the imperial court to promote steam locomotives.

Gao Huan said: "No problem, but when the Taijin Railway is completed, I asked the steam locomotive to be online immediately."
