The students were excited, and even when they discussed it, it seemed that they had forgotten that Xia Hongsheng was still there. Xia Hongsheng www.biquge.info who wrote the pen was also unconcerned, laughing and listening to their lively discussion on the side.

After a long time, everyone suddenly remembered that Xia Hongsheng was still there, and he was left aside, so they hurriedly saluted and apologized: "The mountain chief forgives the sin, and the students are excited for a while, and they usually discuss it like this, and they forget that the mountain chief is still there for a while." ”

Xia Hongsheng smiled and waved his hand, and said: "This is very good, I am very pleased to see that you can study so together." ”

"I don't know if there are any other improvements that need to be made, please make it clear to the master!" Li Tai asked again.

Xia Hongsheng looked at the railroad tracks, then at the bucket car and the cable, smiled, and asked, "You thought of using the steam engine to drive the runner to do work to tighten the cable and drag the bucket car." Didn't think about using a steam engine to drive the wheels directly? Imagine that the steam engine drives the runner, and the runner directly drives the wheel to rotate through the connecting rods and gears, not through the cable, so that the bucket truck can run? Haven't you ever thought about combining the runner and the wheel into one, and then directly driven by the steam engine to make a rotational motion and run directly? ”

Everyone was stunned for a moment, and then slammed their heads, and suddenly shouted: "Yes! Why didn't the students think of using the wheel as a wheel! Wouldn't that be the steam engine itself that would be able to run back and forth! ”

"But, Master, if that's the case, the steam engine is so huge, how can it go down into the mine and pull things out?" Li Tai thought for a moment and asked.

When everyone heard this, they said, "Yes! Master, if the runner is directly used as a wheel, how can the steam engine be so big? ”

Xia Hongsheng laughed: "Is it possible that there are only mine caves in this world?" Let me ask you, if there is a batch of heavy ore-like goods at present, to be transported from Chang'an to Liaodong, how many people, how many horses, and how long will it take? ”

"This ......" everyone was speechless for a while, so they had to say: "I'm afraid it will take a long time!" ”

"Then just imagine, if the railroad tracks are laid from Chang'an to Liaodong, and then the steam engine is used to directly drive the runner, and the bucket car is hooked one by one, and it goes to Liaodong, how long will it take?"

Seeing that everyone looked at me, I looked at you, and couldn't tell, Xia Hongsheng said again: "It's the same time for a cup of tea, how many times can the wheels of the carriage turn, how far can it be transformed into growth?" How many times can the runner driven by the steam engine rotate, and how far can it be transformed? You don't know the difference, do you? ”

Everyone was silent for a while, only to hear Li Tai suddenly clapping his hands and saying: "What Shizun means is that the steam engine is used to directly drive the runner, the runner is the wheel, and the steam engine is the horse that pulls the cart, but this horse has great momentum and speed. It can pull things that are much heavier than a horse-drawn cart and is extremely fast. If there is such a railway track from Chang'an to Liaodong, and then drive it with a steam engine, I am afraid that it will be there in less than half a month! If it is pulled by a horse-drawn carriage, it is estimated that it will take at least half a year! ”

Xia Hongsheng nodded: "The morning and the evening are coming, and it doesn't have to be just a dream!" ”

The students had already understood at this time, and when they heard Xia Hongsheng's words, they couldn't help but be shocked and excited.

What is the speed at which the morning and the evening come?

From Chang'an to Liaodong, 800 miles is urgent, and it takes a few days. But 800 miles can be rushed, one person and one ride, and each post station on the road must be replaced with the best horse to do it. And with what the master said...... One hundred and ten people, countless goods, can do 800 miles of expedited speed! It takes a few days to travel from Chang'an to Luoyang by carriage, and if you have that speed, wouldn't it be a day?!

As soon as they thought of this, the students were extremely excited.

As soon as they thought of the miraculous creation as swift as the flying sword of an immortal, if it would be made from their own hands, so that everyone in the world could have the ability to travel thousands of miles like an immortal, the students present suddenly felt full of strength, and even their blood was boiling like water in the boiler!

Xia Hongsheng looked at this group of excited students from the side, and looked at the posture in his heart, within ten years, I don't know if the train can come out.

Encouragement, encouragement. Li Tai and his team returned to the improvement of the steam engine and railroad tracks, and Xia Hongsheng also left the academy and returned home—he still had important things to do.

Wang Xuance and Belus had already arrived, and were waiting in the front hall, when they saw Xia Hongsheng going back, so they got up.

"Forgive your sins, forgive your sins, there are some chores in the academy, I got up early today and went to deal with it, but I asked His Royal Highness the prince to wait for a long time." Xia Hongsheng saw the two of them get up, so he smiled and said.

"It's okay, it's okay, it's Xiao Wang who is too anxious, and he hurried over early in the morning, but it's disturbing Brother Xia's business." Belus laughed.

"Your Royal Highness the Prince, you have already prepared it and can demonstrate it to His Royal Highness the Prince at any time." Xia Hongsheng said to Belus: "Seeing that it is already noon, will His Royal Highness the Prince go immediately, or will he go over after lunch?" ”

Belus smiled: "Xiao Wang is really itching in his heart, and he is eager to watch, so why don't you go now!" ”

"Okay." Xia Hongsheng nodded: "Your Highness, please come with me." ”

Xia Hongsheng took Qi Yong, and the four of them walked out of the Xia Mansion together, and went to the open space that had been prepared for a long time.

It was a wasteland, but it is still now, and there will be no people.

When I got there, I saw a flock of sheep first, and I was watching a few family members.

"This is ......," Belus said, referring to the flock.

Xia Hongsheng explained: "How can the light of earth-shattering thunder show its power? These sheep are equivalent to enemy soldiers on the battlefield. ”

While speaking, Xia Hongsheng took out two more earbuds, handed them to Belus, and said: "Qi Yong and I have listened a lot on the battlefield and adapted a little. His Royal Highness the Prince is the first time, and the sound of this earth-shattering thunder is quite loud, so it is better for His Royal Highness to wear earplugs. ”

Belus saw that Xia Hongsheng and Qi Yong didn't wear it, so he smiled and said, "It's okay, since Brother Xia doesn't wear it, then Xiao Wang doesn't wear it either." ”

Xia Hongsheng didn't persuade him again, but just gestured to Qi Yong.

Qi Yong understood, raised his hand and felt a round iron bump.

"Your Highness, this is the Heaven-Shaking Thunder." Xia Hongsheng pointed to the heaven-shaking thunder in Qi Yong's hand and said, "This thing is extremely powerful, after igniting the line above, it must be thrown far away immediately." ”

Belus took the earth-shattering thunder from Qi Yong's hand, took it in his hand and looked left and right, looked back and forth, and for a long time, he couldn't see the reason, so he gave it back to Qi Yong.

"Qi Yong, throw it at the flock of sheep and demonstrate it to His Highness." Xia Hongsheng ordered Qi Yong.

"Yes, Childe!" Qi Yong responded, threw the earth-shaking thunder in his hand, and then took out the fire fold, blew it hard, got the fire fold, and then ran forward for a distance.
