The Happy Prince of Tang Dynasty

Everyone was used to Song Luai's habit of asking questions, so they didn't say anything and waited for Li Jiancheng's answer!

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

"Burn?" Not only Song Lu was puzzled, but everyone present was also puzzled. Could it be that simple?

"That's right, it's burning!" Li Jiancheng reconfirmed.

Dugufeng hesitated for a moment, and asked: "Brother Jiancheng, according to what you said, coal is so easy to use, so why have we basically never heard of it?" [

"Hehe!" Li Jiancheng chuckled and scratched Dugufeng's nose.It made her very shy, but she was still very happy in her heart.

"Of course, I mean that the use of coal is very simple. But there are other aspects of work to be done. For example, coal detection, mining, etc., seem simple, but in fact it is not easy." Li Jiancheng explained softly.

After listening to his words, everyone suddenly realized, if it is really as simple as Li Jiancheng said, why is coal rarely heard of?

"Ahem..." Song Que, who had been listening all the time, made a rare speech, "Nephew, what do you mean by exploration and mining?" After speaking, he turned his head a little embarrassed.

The corners of Li Jiancheng's mouth curled up, and he smiled maliciously!But after being glared at by Song Que, he put away his smiling face. "The so-called detection is to find the gathering place of coal, and mining is to dig out the coal."

"But..." the impatient Song Lu was only halfway through speaking before being interrupted by Li Jiancheng.

"Are you trying to tell me why I can get it so easily?" Li Jiancheng asked, turning his head.

"Uh!" Song Lu nodded depressedly.

"There are two types of coal mines!" Li Jiancheng raised two fingers on his right hand as he spoke, and everyone who seemed to be about to talk about Li Jiancheng immediately became quiet and listened to what Li Jiancheng said. "One is an open-pit mine. To put it simply, the coal is above the ground and can be seen everywhere; while the other is buried under the ground. At this time, it is necessary to rely on detection techniques to find it."

Pause for a while, give everyone some time to digest, and then continued: "Mining coal is not so easy! If the mining is not good, it will explode in the hand, and it will collapse and die in severe cases. Therefore, I have not studied it, and I will die indiscriminately. Mining is terrible! As for why I can get coal so easily, it is because there are many open-pit coal mines in Taiyuan, and I can mine it casually."

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

"As for the coal hidden deep in the ground and the advanced mining technology, I don't know very well, so I can't give you a detailed introduction." Li Jiancheng said naively.

"Hehe..." Song Que smiled and said, "Even so, it's not easy for my nephew."

What Song Que said is not wrong. Not only has Li Jiancheng reached the realm of a master at such an age, but he is also knowledgeable and talented. His youth and riches are all based on his own business. In addition, he is also a handsome man, which is exactly what every Huaichun girl thinks of. Prince Charming.

"Uncle's praise!" Li Jiancheng said with some embarrassment.It is thanks to time travel that I can be so powerful, otherwise Li Jiancheng's real fate is heartbreaking.

After being humble for a while, Li Jiancheng calmed everyone down, and then continued: "First of all, the coal should be lit, and a stove should be built where the coal is lit, and a boiler should be placed on it, and water should be added to the boiler to seal it. .Finally connect the boiler to the steam engine!"

"This..." Everyone was dazed after hearing this, and some of them didn't understand very well. They really wanted to ask questions, but they were embarrassed.

And Song Lu rarely asked a question!But after being glared at by Song Que, Song Lu stood up aggrieved, "My nephew, can you explain it clearly?"

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

"Use coal to boil water to form air pressure, and finally drive the rotation of the steam engine."

"According to my nephew, we only need to boil water, so why use coal?" Song Zhi asked puzzled.

"Second Uncle's question is right!" Li Jiancheng praised.After listening to Li Jiancheng's words, Song Zhi bowed his hands humbly.

On the other hand, Song Lu was very dissatisfied when he heard it. Could it be that what he asked was not an idea?But looking at Song Yuzhi behind Li Jiancheng, and stroking his beard, he finally put his dissatisfaction in his heart.

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

"..." Everyone was puzzled again.

"Uh!" Looking at the expressions of everyone, Li Jiancheng couldn't understand why.However, he still patiently explained: "It's actually very simple. If you have ever burned a fire, you know that if you want to make the firewood burn, you must reach a certain temperature. And if you want the water to boil, you must also reach a certain temperature!" After boiling, to make it form water vapor, it needs a higher temperature, and ordinary burning things can’t reach this temperature, only coal can.”

"Oh!" Everyone responded in unison, as if they all understood.

However, Li Jiancheng glanced at it from the corner of his eye, and at least saw the doubts on the faces of Song Lu, Song Yuzhi, Fu Junqiang, and Shan Wanjing. As for the others, they didn't know if they understood. It was better to cover it up. Anyway, he didn't see the doubts of others expression.

Without waiting for anyone to ask questions, Li Jiancheng continued to explain: "When the temperature is high enough, water will change from a liquid state to another state, that is, water vapor, which is a gaseous state!"

"I see!" After hearing Li Jiancheng's words, another excited voice rang out.Everyone turned around and saw that it was Song Yuhua, a talented woman.

Song Yuhua is not as restrained as he was at the beginning. Looking at everyone looking at himself, he said confidently: "Just like when we boil water, after the water boils, we open the lid, and white mist often rises. This white mist is Brother Li. The water vapor in your mouth, right?"

"Smart!" Li Jiancheng snapped his fingers happily. It's a good mood when someone understands.

After being praised by Li Jiancheng, Song Yuhua, the talented woman who had been talking about it in front of everyone just now, lowered her head a little shyly.

Seeing the tacit understanding between her elder sister and elder brother Li, Song Yuzhi felt a little apprehensive, but she thought it was her own elder sister, so she didn't think too much about it.

"Having said so much, I think everyone understands the same! Now let's watch the steam engine start!" After Li Jiancheng finished speaking, he gave instructions to Zhang Kangnian who had been waiting by the side.

Then Zhang Kangnian passed on the order, and after a while, many people came and saw them carrying a lot of coal and putting it in front of the boiler.

After receiving Li Jiancheng's instructions, he quickly threw the coal into the stove.

"Gurgling..." Not long after, everyone heard the sound of boiling water coming from the boiler.

Stretching their necks to stare at the boiler, finally, everyone only saw gas rushing through the pipe connecting the boiler and the steam engine at an extremely fast speed, and then the big wheel on the steam engine slowly turned, and then the small one The wheel also moved!The speed of the last two runners gradually increased, and finally reached the point when everyone could not see clearly.

"Datang Xiaoyao" moved!

Everyone only felt that the hull of the ship shook for a while, and then they had a feeling that they were moving forward. [

"Do you understand?" Li Jiancheng asked with a smile.

"En!" This time, everyone responded in unison, and no one had a puzzled look on their faces.Judging by their looks, they seem to understand.

Sure enough, the great man was right: practice is the only criterion for testing truth.No, let them watch the operation process of the steam engine, which is more effective than what he said for a long time.Thinking of this, Li Jiancheng was a little puzzled. If he had known earlier, he would just let them see it, and he wasted half a day of saliva!

"Boom, boom!" At this time, everyone under the cabin realized that the sound after the ship started was even louder than before, and they couldn't help covering their ears.

Li Jiancheng didn't speak when he saw him, and left the cabin first.When everyone saw it, they also followed up consciously.

"Huh!" When they came to the deck, everyone let out a sigh of relief.The dream fever and the ear-shattering voices under the cabin just now disappeared a lot, and the sea breeze blew my mind soberly.

"Hey!" Song Que sighed as he saw the "Da Tang Xiaoyao" sailing rapidly on the sea.

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

As if sensing Li Jiancheng's gaze, Song Que looked over and said, "I just sigh that the ship can reach such a speed. My Song family's previous fleet is not worth mentioning at all."

"Hehe!" Li Jiancheng smiled brightly, and under Song Que's puzzled gaze, he finally explained: "Now the Song family and my Li family are in an alliance, and Jian Jiancheng will give this technology to the Song family, so uncle has nothing to worry about. "

"Haha! I was thinking about how to ask for it, but I didn't expect my nephew to deliver it to my door, which saved my mouth." Song Que looked at Li Jiancheng with a wicked smile like a fox who had succeeded in tricks.

Li Jiancheng is so depressed!I didn't expect to be posed by this old guy.

If Dugufeng and Fu Junmei knew that Song Que had taken advantage of Li Jiancheng, they would definitely persuade Song Que!It's a pity that they don't know, which also caused everyone to suffer together.

Sure enough, Li Jiancheng yelled: "Zhang Kangnian, pass on the order and move forward at full speed, let our Song lord feel an extraordinary feeling."

"Decree!" Zhang Kangnian ran away quickly after performing the military salute prescribed by Li Jiancheng.

In just a moment, the "Da Tang Xiaoyao" opened at a speed faster than what everyone had seen before...
