Li Changfeng did not refuse, and had an in-depth discussion with Liang Dafu on the details of various aspects of the steam engine.

Li Changfeng, who received a modern education in his previous life and was involved in all aspects, every time he put forward some suggestions for improvement, he could make Liang Dafu stunned when he started the shooting.

"Your Highness, I think you should let go of the worldly distractions and come with me to engage in scientific research, this is what you should do!"

Liang Dafu looked serious.

Li Changfeng said with a smile: "If this prince engages in scientific research with you, who will earn scientific research funds for you?" ”

Liang Dafu knew that this was impossible, and said with a dry laugh: "Yes." ”

"The successful development of the steam engine is just the beginning, the most important thing is to use it!"

"I haven't really thought about that."

Li Changfeng began to guide: "You say, if you put wheels on the transmission shaft, what will happen?" ”

Thanks to Li Changfeng's frequent exposure to it, Liang Dafu naturally knew what the propeller shaft meant.

Liang Dafu's eyes immediately lit up: "Then it will be like a carriage, walking on the road!" ”

Speaking of this, Liang Dafu's expression became excited: "Moreover, this is much stronger than a carriage, as long as there is coal and water, it will run tirelessly, and the carrying capacity is incomparable to that of a carriage!" ”

Li Changfeng nodded with satisfaction: "That's right, this prince is very pleased that you can find this, this is your next research direction." ”

"But ......" Liang Dafu thought for a moment, frowned and asked, "What should I do if such a big guy turns?" Also, the weight of the steam engine is too amazing, not to mention the roads in the capital, even the asphalt roads in Baishi City can't withstand the pressure! ”

Li Changfeng continued to guide: "Then we can change our thinking, since the road is not good, why not lay the rails?" After the roadbed is tamped, stones are laid, and the rails are fixed with anticorrosive wooden strips......"

Next, Li Changfeng described in detail the method of rail manufacturing and related operation methods according to his memories of the railway of the train in his previous life.

The more Liang Dafu listened, the more excited he became, and he exclaimed again and again.

After saying this, Li Changfeng said that he wanted money to give money to people, and asked Liang Dafu to let go of it, and left the scientific research institute after some encouragement.

The world of the steam engine is undoubtedly epoch-making.

But the most important thing is to use it.

Steam trains are undoubtedly the best choice.

Once put into use, no matter whether it is to transport people or goods in the future, it will bring him huge profits.

And it's a monopoly business.

Of course, it can also stabilize the whole job.

"It would be nice to have an internal combustion engine when we got it."

Li Changfeng slapped the soot on his body and couldn't help but sigh.

He had already mastered several oil fields, and even low-grade gasoline and diesel had been initially developed, but they had no other use than to set fires.

If the internal combustion engine can be built, it will not be far from the car, and life will become very convenient at that time.

However, Li Changfeng also knows that this cannot be achieved in a short period of time.

The internal combustion engine is too complex, and only after the steam engine technology is mature and relevant experience is accumulated, can the internal combustion engine be better developed.

In the next few days, Li Changfeng has been staring at the expansion of honeycomb coal production and sales channels, and has found a few businessmen to sell them in the cities around the capital.

Honeycomb coal is expanding at a breakneck pace, gaining more recognition from the people, and its income is growing every day.

Since the honeycomb coal began to be sold in large quantities, Li Changfeng was surrounded by a large number of masters at all times, either bright or dark, and he did not encounter any danger, and the Zhao family was very peaceful and did not do anything out of the ordinary.

This surprised many people who were determined to have something big going on.

The Zhao family swallowed their anger like this?

How did they know that Zhao Tianquan couldn't bear to swallow his anger, and with the two families of the Zhao family and the Wang family, they didn't dare to do anything to the Li royal family.

It's getting colder.

This has led to a slowdown in the growth of vegetables in the greenhouse, and the supply of ingredients at the Hudi hot pot restaurant is a little tight.

Anyway, all the money earned is the money of the magnates, Li Changfeng directly announced a price increase of 30%, although the magnates were dissatisfied, but it did not affect the business of fishing at the bottom of the lake at all.

The colder the weather, the more precious the green vegetables.

Then Li Changfeng personally went to the vegetable greenhouse, and pointed out some details of thermal insulation on the spot, so that they could regenerate some heaters at any cost to ensure the temperature of the greenhouse.

The value of these vegetables is much higher than the coal that is burned.

In addition, the demand for honeycomb coal is also increasing, and the output of Li Changfeng Coal Mine is a little tight.

Coming out of the vegetable greenhouse, Li Changfeng took a carriage back to Beijing.

There was an improved stove in the carriage, and there was a special chimney sticking out of the carriage to emit smoke, and the inside of the carriage was very warm, and Li Changfeng felt a little hot even in a thin shirt.

The carriage swayed all the way, and it was not long before it suddenly stopped, and a loud noise came in.

Li Changfeng opened the thick cotton curtain and asked, "What's wrong?" ”

The groom hurriedly turned around and bowed and said, "Your Highness, it is a member of the Five Cities Soldiers and Horses, who are driving away the refugees who are trying to enter the capital. ”

The groom spoke in a low tone, with a look of unbearability.

Li Changfeng was stunned, then lowered the curtain, put on a thick sheepskin coat, then lifted the curtain and jumped out of the carriage and walked towards the refugees.

"Your Highness, refugee status has not been investigated, and you must not go!"

The master of the inner group arranged by Emperor Qianwu hurriedly went up to stop him, but was pushed away by Li Changfeng.

"It's fine."

Seeing this, Zhao Shanhe, who was investigating the situation in front, hurriedly came to Li Changfeng's side to protect him, and when he saw Li Changfeng's gloomy face, he didn't speak and followed closely to the side.

Li Changfeng is in a very bad mood now.

He doesn't think he's a good person in the true sense of the word, but he really can't bear to see ordinary people who don't even have any hope of living.

I saw that there were about 1,000 of these refugees, all dressed in thin clothes, only a few wore winter clothes, many did not even have shoes, and their feet were frozen black.

The refugees looked haggard and their faces were yellow, and they looked like they had not eaten for a long time, shivering in the cold wind, kneeling on the ground and kowtowing to the officers and soldiers wearing official uniforms and holding swords.

"Please, master, let's go in, my children are about to freeze to death!"

"I haven't eaten in two days, please let us go in and beg for food!"

"Uncle, you can do it, okay, if you can't do it, you can buy my child, as long as you give him a bite to eat, don't freeze to death and starve to death!"

……

However, these officers and soldiers looked indifferent, brandished the long knives in their hands and grinned and threatened: "Let me die far away, is the capital a place where you homeless people can come?" ”

"You poor sour things, don't dirty the eyes of the old men in the capital, if you dare to stay again, you will be killed on the spot!"

At this moment, an angry shout came.

"Kill on the spot? Who gave you the power?! ”

The officers and soldiers were shocked.

Looking around, I saw Li Changfeng walking briskly with a gloomy face surrounded by many escorts.
