Like the Royal Academy of Engineering and Ordnance, the Ming Shipbuilding Bureau often caused frequent fires due to the accumulation and utilization of large amounts of flammable materials.

Therefore, the buildings of the Daming Shipbuilding Bureau are no longer wooden structures, just like several natural science research institutions in the capital, but are buildings made of the latest concrete wall structures.

In this era, this type of building is not expensive, so it has not been fully popularized, so it does not challenge traditional Chinese wooden structures. Of course, the artistic and aesthetics of traditional wooden structures cannot be replaced by concrete buildings.

Moreover, at this time, the Ming Shipbuilding Bureau, like the steel smelting base affiliated to the Ordnance, was criticized by local military and civilians, because looking at the black smoke in the sky, you know that it was a heavy pollution enterprise.

The county magistrate here even sued Zhu Youxiao, impeaching Mao Yuanyi, the head of the Ming Dynasty Shipbuilding Bureau, to pollute the holy vein, poison the fertile land, and aggravate the people's illnesses!

Zhu Youxiao did not blame the county magistrate, and even praised the county magistrate in front of the cabinet. He was the first Ming official to recognize the problem of environmental pollution. His foresight seems to be ahead of the current world by hundreds of years.

Moreover, Zhu Youxiao directly promoted the county magistrate to be the inspector of the Northern Zhili Censor, and was fully responsible for the relocation of residents near the Shipbuilding Bureau of the Ming Dynasty, including major heavy industrial bases in the capital.

There is no way to solve the damage to the natural environment brought about by the exhibition process, even in the 21st century, not to mention that in the Ming Dynasty today, under the influence of limited capital costs, technical strength, and national consciousness, in order to prevent local people from paying the price of their lives due to these heavy industrial pollution, Zhu Youxiao could only let them move out of their hometown. This is the only effective solution now.

Under the dark chimney are rows of factories and docks, while the Haihe River near the docks is already dark and seems to have poured ink into it.

But it is also precisely in such a filthy black sea river that you can hear the sound of whistles that will only last hundreds of years, and you can even see a steam ship that has taken shape heading towards the estuary of the sea river.

This is the second steam-powered ship of the Ming Dynasty to be launched and put into service. Its size, draft and even degree are even stronger than the "Zheng He". Of course, it still has not broken through the shackles of truly realizing all iron armor transformation.

Xu Guangqi, the Grand Secretary of Wenyuan Pavilion, and Yang Sichang, the Left Minister of War, were standing on the deck of this steam-powered ship. This was the first time they had come into contact with such a ship that did not rely on manpower to paddle, and naturally they were deeply moved in their hearts.

Especially Yang Sichang, the left assistant minister of the Ministry of War, was different from Xu Guangqi. He was not as good as Xu Guangqi, a pioneer in Western learning in natural sciences. Therefore, now he just like Liu Laolao entering the Grand View Garden, constantly touching here to see where, and even asked Mao Yuanyi on the side: "Zhisheng (Mao Yuanyi's name is Zhisheng). What exactly does this ship rely on? Why can he run away by himself? And it's very fast. I think someone burns coal here. Could it be that the flames of burning coal can make the ship move?"

Mao Yuanyi couldn't help but sneer, and did not dare to make fun of the War Department officials who knew nothing about natural science. He held back his smile and explained: "Mr. Yang, this is not as simple as burning coal. To be precise, he transferred the heat energy generated by the combustion of coal to water, so that the water was converted into mechanical energy in the form of water vapor, which was to drive the bearings in the cylinder, and then rotated the propeller below through the bearings. However, the loss caused by this process was huge, basically burning hundreds of kilograms of coal, which only allowed our ship to travel a short distance. Therefore, the reason why this ship was built was not only to install more cannons, but also to install more coal."

"Well, since that's the case, why can't we find a way to convert all the thermal energy after the coal is burned into the mechanical energy you mentioned? Will this make the ship faster?" Although Yang Sichang didn't understand this aspect very well, he was not stupid. He could roughly understand what Mao Yuanyi said, and even consistently learned from one example.

Xu Guangqi and Mao Yuanyi smiled secretly. They both taught themselves a lot of natural science theoretical knowledge at the Royal Academy of Sciences. It was a fact that they had to admit that the conservation of energy could not be 100% passed on. Because they still did experiments under the opposition of Zhu Youxiao but still failed. So when they heard Yang Sichang, the rookie mentioned this, they didn't know what to say.

But it was not too cold, Xu Guangqi had to say from the side: "Mr. Yang, this is the reason, but the heat energy generated when coal burns is not only transmitted to the water, but also to you and me. Think about whether you are boiling water on the stove and your water is boiling, do you feel warm? This is, according to Your Majesty's words, it is generated when electronic movements. I don't know what electrons are. This is what Your Majesty and his heavenly books said."

Yang Sichang wanted to ask again, but seeing that Xu Guangqi and Mao Yuanyi had turned their heads, it was hard to ask again. He thought that he could only go back to the Royal Academy of Sciences to study hard. He heard what Mao Yuanyi said about hydrogen, helium, lithium, beryllium, boron and thermodynamics. He knew nothing and could not understand it at all.

But this time he came to inspect the Beihai Fleet, not the Shipbuilding Bureau of the Ming Dynasty, so he did not ask further. After all, the main person in charge of inspecting the Shipbuilding Bureau of the Ming Dynasty was Xu Guangqi, and only Xu Guangqi could understand Mao Yuanyi's heavenly book-like things.

Yang Sichang had never had the awareness of paying attention to marine strategy before, but since he participated in military aircraft with Zhu Youxiao, he gradually realized that this was the real life gate for the future of the Ming Dynasty. It can be said that although there are tigers and wolves in the north, they are just fierce on the surface, and their strength will only take one or two years. On the ocean, the rising Folang Ji people and the Red Witches are the great troubles for the future of the Ming Dynasty and even the entire Han people.

For this reason, Yang Sichang himself made up for several months of marine knowledge. This time he came to the Beihai Fleet with a familiar attitude, so his attitude seemed very humble and sincere. Qin Botong and Heiwa and other officers of the Beihai Fleet did not feel too strongly disgusted with him.

After Yang Sichang and Xu Guangqi inspected the Ming Shipbuilding Bureau and the expanded Beihai Fleet in accordance with Zhu Youxiao's will, and returned to the capital with Li Mingrui, the Grand Secretary of the Cabinet, Zhu Youxiao began to prepare for the reorganization of the Beihai Fleet.

According to Zhu Youxiao's intention, the Ming Dynasty court would no longer care about his Zheng family pirates and directly established the Ming Dynasty Royal Imperial Guard Navy, and the fleet would be directly expanded into three fleets, namely the North Sea Fleet, the East Sea Fleet, and the South Sea Fleet.

After recovering from injury, Gu Sanmazi was directly appointed as the general officer of the South China Sea Fleet. His first task was to take his fleet directly to the south, pass by the Zheng pirates' control area to the Pearl River field, and assist the governor of Guangdong and Guangxi Shang and Zhou Zuo to remanage Macau.

According to Zhu Youxiao's intention, Macau cannot be so confused that it becomes a free place for the Westerners.
