Everyone is accustomed to the habit of Song Luai asked questions, so he did not speak, and waited for Li Jiancheng's answer!

"The use of coal is very simple, just one word -burned!" Li Jiancheng said with a smile.

"Burning?" Not only Song Lu was wondering, but even the people present wondered. Is it that simple?

"Yes, it is burning!" Li Jiancheng confirmed again.

Dugufeng hesitated and asked: "Building a brother, according to your statement, coal is so simple and available, so why have we not heard of it?"

"Oh!" Li Jiancheng laughed and scratched her lonely phoenix's nose. She made her shy, but she was still very happy.

"Of course, I mean the usage of coal is very simple. But there are other aspects of work to do. For example, the detection, mining, etc. of coal looks simple, but it is not easy." Li Jiancheng explained softly.

After listening to him, everyone suddenly realized that if it was really as simple as Li Jiancheng said, why rarely hear the coal?

"Cough ..." Song Que, who has been listening to, spoke once, "What do you mean by the detection and mining you said?"

Li Jiancheng's mouth was tilted, and he smiled with some unhappy! But he glanced at Song Que, and then put away his smiley face. "The so -called detection is to find a gathering place for coal, and mining is to dig out the coal to dig out.

. ""

"But ..." Song Lucai, who was anxious, said half of them, and was interrupted by Li Jiancheng.

"Do you want to say why I can get it so easily?" Li Jiancheng twisted his head and asked.

"Uh!" Song Lu nodded depressed.

"There are two types of coal mining!" Li Jiancheng said that two fingers were erected in his right hand, and seeing that Li Jiancheng seemed to be a big talk, he suddenly calmed down and listened to Li Jiancheng's description. "One is an open -air mine,

The simple point is that the coal is on the ground and can be seen everywhere; and the other is buried under the ground. At this time, it is necessary to rely on the detection technique to find it. "

Set up for a while, give everyone some time digestion, and then continue to say: "It is not easy to minimize coal! If the mining is not good, it will explode, and it will collapse.

Mining is terrible! As for why I can get coal so simple, because there are many open -air coal mines in Taiyuan, they can be mined casually. "

"Oh!" After listening to Li Jiancheng's explanation, everyone suddenly realized.

"As for, I am not very clear about those hidden coal and advanced mining technology, so I can't introduce you in detail." Li Jiancheng said helplessly.

"Hehe ..." Song Que smiled and laughed: "Even so, the nephew is not easy."

There is nothing wrong with Song Que. Li Jiancheng not only reached the realm of the master at the age, but also learned more talents. He was a lot of money to start his own business. In addition, people are also Yushu Lingfeng.

Prince White Horse.

"Uncle's fallacy!" Li Jiancheng was a little embarrassed. He could be so powerful but he supported the credit, otherwise Li Jiancheng's real fate was heartbreaking.

After being modest, Li Jiancheng let everyone calm down, and then continued: "First of all, you must ignite the coal and set up a stove at the place where the coal ignite.

. Finally, let the boiler connect to the steam engine! "

"This ..." Everyone didn't understand some of them when he heard it, he wanted to ask questions, but he was embarrassed.

And Song Lu did not ask questions! But after Song Lu glanced at Song Que, he stood up wronged. "I said the nephew, can I explain it clearly?"

Li Jiancheng was helpless, very embarrassed, and depressed, but he still explained carefully.

"Boil water with coal to form air pressure, and finally drive the steam engine to rotate."

"According to the nephew, as long as you boil water, why use coal?" Song Zhi asked puzzledly.

"The second uncle asked about the idea!" Li Jiancheng praised the sentence. After listening to Li Jiancheng's words, Song Zhi's humble arched hand.

And Song Lu on one side was dissatisfied with it. Isn't he asked about it? But look at Song Yuzhi behind Li Jiancheng, and then touched his beard, and eventually put his dissatisfaction in his heart.

"The reason why coal is used is also related to the boiling point."

"..." The crowd puzzled again.

"Uh!" Looking at the expression of the crowd, Li Jiancheng couldn't know why. But he still explained patiently: "In fact, it is very simple.

Temperature. To make it boil, it is also necessary to reach a certain temperature! After boiling, to let him form water vapor, then it will be higher, and the general burning thing cannot reach this temperature.

Only coal can be reached. "

"Oh!" Everyone responded neatly, and it seemed to understand.

However, Li Jiancheng glanced at Yu Guang, at least seeing Song Lu, Song Yuzhi, Fu Junzheng, Shan Wanjing's doubts on the four people's faces. As for others, I didn't know if they understood it or cover it well.

expression.

Without waiting for someone to ask, Li Jiancheng then explained: "When the temperature is high enough, the water will change from liquid to another state, that is, water vapor, that is, the atmosphere!"

"I know!" After listening to Li Jiancheng's words, another excitement sounded. Everyone turned around, it was Song Yuhua, a talented girl.

Song Yuhua is not restrained at the beginning of the moment. Looking at everyone looking at himself, he confidently said: "Just as when we burn the water, after the water is boiling, the lid is opened. There will often be white mist rising. This white mist is Brother Li Li.

The water vapor in the mouth? "

"Smart!" Li Jiancheng made a good ring, and someone understood that the mood was good.

After being praised by Li Jiancheng, Song Yuhua's talented woman who had just talked about in front of everyone, at this time, was a little shyly lowered her head.

Seeing that her sister and Brother Li were so tacit, Song Yuzhi had some taste in her heart, but I thought about it, so I didn't think about it.

"After saying so much, everyone must understand it too! Now everyone will look at the launch of the steam engine!" Li Jiancheng finished speaking, and issued a instruction to Zhang Kangnian, who had been waiting next to him.

Later, Zhang Kangnian passed the instructions. After a while, many people came. I saw that they carried a lot of coal and put them in front of the boiler.

After getting the instructions of Li Jiancheng, quickly throwing the coal into the stove.

"..." It didn't take much time, everyone heard the sound of boiling water in the boiler.

Stretching the boiler with a stretching neck, and finally, everyone only saw the tube connected to the boiler and the steam engine, and the gas rushed over at a very fast speed. Then the large rotor on the steam engine slowly rolled up, and then the small one of the small one

The turntable also moved! The speed of the last two rotors slowly accelerated, and finally reached the time when everyone could not see it clearly.

"Datang Xiaoyao" moved!

Everyone only felt that the hull was shaking, and then a feeling of being moving forward.

"Look at it?" Li Jiancheng asked with a smile.

"Well!" This time everyone responded uniformly, and no one had a doubtful look on their faces. Looking at them, they seemed to understand.

Sure enough, the great man said right: practice is the only criterion for testing the truth. No, let them see the operation process of the steam engine, which is more effective than he said. Thinking of this Li Jiancheng, he was a little puzzled. He knew that it would be given directly to let me directly let it.

They just see it, and they waste their saliva for a long time!

"Boom, bombardment!" At this time, everyone who was under the cabin found that the sound of the ship started after the start of the ship.

Li Jiancheng did not speak when he saw it, and took the lead in leaving the cabin. Everyone followed it and followed it.

"Huh!" When he came to the deck, everyone took a breath. The dream heat and the sound of the shock ears just under the cabin had eliminated a lot. They were blown by the sea breeze, and the brain was sober a lot.

"Hey!" Watching the "Datang Xiaoyao" driving quickly on the sea, Song Que sighed.

Li Jiancheng looked at him puzzled, but didn't say anything!

It seemed to feel Li Jiancheng's glance.

"Oh!" Li Jiancheng smiled clearly. Under Song Que's doubt, this explained: "Now the Song family and my Li family are alliances. The establishment of the Song family will give this technology to the Song family.

"

"Haha! The old man thought about how to discuss it, but did not expect that the nephew was delivered to the door, and it saved the old man's saliva." Song Que looked like a fox with a trick, looking at Li Jiancheng with a smile.

Li Jiancheng's depression! I didn't expect to be put on the old guy.

If Dugufeng and Fu Junxuan knew that Song Que had occupied Li Jiancheng's cheap, then they would definitely persuade Song Que! Unfortunately, they did not know, which also caused everyone to suffer together.

Sure enough, I only listened to Li Jiancheng's drinking: "Zhang Kangnian, pass the order, go forward at full speed, let our Song valve owner feel the unusual feeling."

"Light!" After Zhang Kangnian took a military ceremony prescribed by Li Jiancheng, he ran away quickly.
Chapter completed!
