Since Empress Changsun said so, this maid naturally won’t say much.

In fact, there is no need to worry about any problems in Jinyang, because she had already started taking it in the Tang Dynasty because her physical deficit is different from Empress Changsun.

Although there is something wrong with her body, it is invisible, so there is no need to worry about any problems. And if it is repaired for a long time, Jinyang's health will actually get better and better.

In fact, when he came back and almost reached the Han Dynasty, Sun Simiao took their pulse again. Sun Simiao said that his body in Jinyang was basically no problem with normal children, but he was weaker, but he could exercise. If he continued to take Lingquan water, a year would be enough.

Therefore, Huo Gang naturally doesn't have to worry about what will happen to Jinyang after exercise, not to mention that she doesn't have much exercise. The stable has already prepared in advance. Not only are there small brushes specially made for Jinyang, but also equestrian suits made for Jinyang according to the specifications of later generations.

Little leather boots, leather jackets, etc., she was more flexible when working, and there was a person who specialized in feeding horses next to her. In addition, although she was a pony that had just been born for a month, she was taller than Jinyang, and she also prepared a triangular staircase fixed to the ground for Jinyang.

With two small stairs placed on both sides, the pony was in the middle, she could brush some places that could not reach. Although the pony grew very fast, the pony could almost catch up with the size of an adult horse a year later, Jinyang had no health at that time, and she could contact riding a horse.

Huo Gang taught Jinyang to clean horses here, but the entire Han Dynasty did not stop at all. About a month after Emperor Changsun came to the Han Dynasty, the alfalfa outside had turned the earth green, and the Industrial City finally heard good news.

Huo Gang took the train directly to the Industrial City. This time, Huo Gang came to a brand new factory. When he saw the extracted oil, even though Huo Gang had been in this world for several years, he couldn't help but feel a little excited.

Because this means that Dahan's chemical companies have finally embarked on the right path! Although due to the gap in basic science, for example, there are too few high-end scientists in chemical physics, the knowledge learned by brand new students is even slightly more advanced than in high school.

Huo Gang had obtained a full set of textbooks for the Han Dynasty before, and the higher-end textbooks were gone, and it was all relied on future scholars of the Han Dynasty to supplement it, but in fact... this is enough.

Because Huo Gang himself graduated from a college student, although he is not a prestigious university, he is also a top university in 985 and 211. He has written all the formulas, theories, etc. he learned in the university, and he can remember all the formulas, theories, etc.

Never underestimate these theories and formulas. You should know these things. How many scientists spent in their previous life to prove them? It can be said that they spent their entire lives.

Huo Gang just wrote these formulas and theories, and he could be said to be standing on the shoulders of all giants.

Never underestimate the level of physics and chemistry in high school. If high school knowledge can be transformed from book theory to reality, it can be said that a complete industrial system can be established. There is no problem at all.

So it is no longer a problem for Dahan to open the chemical industry now, and the place where Huo Gang came is naturally Dahan’s first oil refinery.

Oil located in Xinjiang has been mined in later generations. Although the output is not large and the daily output is only a few hundred barrels, because there are no refineries, the oil has been stored and a lot of it has been stored.

Moreover, it has not expanded its production capacity until it continues to make continuous arguments.

Now that the chemical industry is available, this means that the entire Dahan industrial system will be taken to a higher level.

"Good job, all of you have made contributions! The birth of the refinery means the birth of the entire chemical system, and means that at least two-thirds of the products of the chemical industry can be produced. Although these things are very basic, you must continue to work hard." Huo Gang took a deep breath and couldn't help but speak.

At present, there are few products in oil refineries, only gasoline, kerosene, diesel, and some lubricating oils. This is too far from later generations. Later generations, the entire oil-related industries cover almost half of the things in life.

It represents something that supports the modern energy system, and is not a joke.

"I heard that you have already developed the internal combustion engine?" Huo Gang asked.

"Yes, we have developed the diesel engine. With your previous reminder, we have made some cylinders. We have tested all the diesel made with alcohol and small-scale laboratories before." Lu Feng next to him immediately spoke.

"Test it." Huo Gang nodded immediately. Someone quickly pushed a diesel engine over there. The diesel engine was not very large. It was a single-cylinder. Its volume was slightly larger than the diesel engine on the small tractor that Huo Gang had seen later in life, and it looked thicker and heavier.

But in fact, its internal structure is already very delicate. Dahan is now capable of making a cylinder structure, and its starting method is also very simple than Huo Gang's impression, which is hand-cranking engine. There is also a specially filtered air intake next to it. A man was holding a torch next to it and preparing to ignite it.

Huo Gang remembered that when he was very young in his previous life, the tractor at home always had to be placed in the place in winter and then used to ignite. In fact, the diesel engines almost always use compression ignition, that is, the pressure is compressed to high temperature and ignite automatically.

However, because the external temperature is not enough, a little fire can increase the temperature in the cylinder in winter.

The current diesel engine is actually igniting next to it just in case. When a selected soldier walked over, just like Huo Gang remembered when he was a child, he opened the pressure relief valve with one hand, and then started to rotate quickly with the other hand with a shaker.

Huo Gang looked motionlessly, and soon a familiar sound came from the diesel engine. Soon, with the sound of "Woo..." as if it was breathing heavily, then the sound of the "da da da da da" diesel engine started instantly.

A stream of black smoke soon emerged from the chimney placed on the side. When the shaker automatically left, the entire diesel engine continued to vibrate.
