Xiao Jingmao thought thoughtfully: "So that's the case?"

"Isn't that because I didn't take into account the chamber pressure?"

Qin Feng looked annoyed, pointed to a device installed on the boiler, and shouted: "This time I added a pressure relief valve to this boiler, as long as the pressure exceeds a certain level, this piston can be pushed up, and the steam inside will also come out." In this way, the boiler explosion can be avoided naturally. ”

Yang Chenglong still refused to give up, and argued strongly: "Even so. But your boiler is too rudimentary. What if you accidentally let a fire come out of the boiler and burn everything on the car?"

"Hmph!" Qin Feng chuckled lightly and said, "What's so difficult about such a trivial matter? As long as you hit the iron plate next to it, you can naturally stop the spread of the fire." ”

"That said. You're too expensive. All of them are forged with 100 refining steel, and I'm afraid that just one will cost a thousand times!" Yang Chenglong shook his head, still maintaining a veto attitude.

"A thousand guan?" Qin Feng shook his head, showing a little annoyance, and shouted: "Do you know that in order to get this thing, I put all my net worth and life into it! ”

Hearing this, Yang Chenglong was even more convinced, and complained: "If it is so expensive, it is even more impossible to use." ”

He's not stubborn, he just doesn't like high-risk things.

After all, if you use a railcar as a means of transportation, the horse can stop at any time and anywhere if something happens.

But if the train is a little careless and something happens, I'm afraid that a car of people will be planted in it.

And listening to what Qin Feng said, but to build such a one, it will cost more than 3,000 yuan, but if it is replaced by an ordinary railroad carriage, it only needs 30 yuan, and the horse can run back and forth.

Qin Feng saw that Yang Chenglong always refused, so he became even more anxious, and shouted: "I said that you guy, you obviously look very smart, why are you so brainless?"

Xiao Jingmao, who was standing next to him, also listened to the content of the debate between the two at this time.

Seeing that the two were arguing, he interjected and laughed: "Since he pleaded like this, why don't you just compete with him?"

"But he really works?" Yang Chenglong asked suspiciously.

"If you don't give it a try, how do you know how effective this thing is?" Xiao Jingmao said with a smile: "What's more, when you first built the railway, weren't you also questioned?

In the distance, Qin Feng shouted: "That's right! Obviously, I helped you at the beginning, but why did you turn your face and don't recognize anyone, and you didn't even give me this opportunity?"

Yang Chenglong shouted: "But this is different!"

"What's the difference?" Xiao Jingmao shook his head and persuaded again: "I know that you are worried that this thing is defective, and if you are not careful, it may lead to an accident." But you should also know that things are not static. We only need to continue to improve, and I think these shortcomings can be eliminated. In that case, why not compare yourself to him?"

Qin Feng persuaded from the side: "That's right. And you've seen the pressure reducing valve, too. I'm telling you very clearly, there will definitely be no last blow up this time. ”

Yang Chenglong saw that Xiao Jingmao was so earnest, so he had no choice but to bow his head and reply: "Since this is the case, then listen to you." Then he looked at Qin Feng in the distance, and said, "It's just that since it's a gambling contract, there must always be a charter on this matter, right?"

"Then how do you say we should compete?" Qin Feng said confidently.

Yang Chenglong replied with his head in his head: "Naturally, it depends on who arrives at the destination first." ”

"Oh, isn't it simple?" Qin Feng's eyes lit up, but he showed a happy expression, as if for him, the so-called failure would never appear.

Yang Chenglong nodded and replied, "Of course!"

Standing aside, Xiao Jingmao also smiled: "Since that's the case, let's start." Then behind Yang Chenglong, he got into a carriage, and the carriage sitting in front of him waved a long whip, and immediately let the horse take a step and walk along the railway and towards the outside.

When Qin Feng saw this scene, he immediately pulled away the whistle next to him.

"Woo......"

The loud voice spread to the four fields, which immediately made the crowd outside suspicious.

"What's going on here?"

They looked together, and immediately saw two cars slowly coming out of the open gate.

One is a traditional horse-drawn carriage, which they have also made many times when they lived in Chang'an City.

But the other car was covered in steel, and while making a roaring sound of "woo-woo", it drove slowly along the railroad tracks towards the distance.

Seeing this scene, some people were taken aback and shouted.

"Isn't this the son of Old Minister Qin? Why did he come here?"

"It's that weird? No wonder you made this thing. After all, this guy is a genius when it comes to mechanics. ”

"It's just a pity to waste your years on this. With such a kid on the stall, Old Minister Qin can be regarded as having poured blood mold for eight lifetimes. ”

“......”

The group talked a lot, obviously recognizing Qin Feng, and Qin Feng was the son of Qin Jian, who had presided over the construction of blast furnaces and artillery in the Red Phoenix Army, otherwise how could he get such a thing, and even ran here, intending to compete with Yang Chenglong?

And those who had never heard of it were also very surprised, and opened their mouths to ask.

"What's going on, why are you so contemptuous of this person?"

"Don't you know, this guy has always been crazy, and in order to make things, he once sold all the family's land. You say it's infuriating?"

"Huh? This guy looks normal, but he didn't expect to do such a thing?"

Those people are also dumbfounded, after all, among the Chinese, they have always had the idea of living and working in peace and contentment, and naturally regard the purchase of land property as the first priority, such as Qin Feng, such as rebellious people, of course, they regard them as outliers.

Just as everyone was talking, the train also came to the starting point with the railroad carriage, waiting for Xiao Jingmao's order.

At this moment, Yang Chenglong was also slightly excited, and said to Xiao Jingmao: "You can start." ”

It took him three years to get it out, and although it had been tested many times before, only today was the first time that the entire line had been tested, and if it was successful, the railway would be operational.

"Of course. I'm always available. ”

Next to him, Qin Feng also raised his eyebrows and laughed loudly.

Seeing the crowd gathered next to him, he was even more excited, and immediately took an iron rod, and made a "clang" sound from the iron furnace, attracting everyone's attention, and then shouted: "Everyone, take a look, take a look, this is the first time the 'Canglong' is running, if you are interested, you can all come up and have a look, how about experiencing the taste of this train?"

Seeing Qin Feng's invitation, a bold young man below took a brisk walk, immediately climbed onto the train, and shouted: "Then let me be the first guest." I just don't know if I want money for this thing?"

"Don't worry. This is the first time to run, no money. Qin Feng smiled and replied.

Seeing that they had not stopped it, the rest of the people also rushed up together, and the carriage, which could only hold twenty people, was suddenly filled.
