The king behind the empress

Chapter 71
Because several master craftsmen are very strong, their speed of building is also very fast.

It didn't take long for a brand new boiler to come out again. In addition to these boilers, there were also some messy parts.

Mo Zizai assembled the various parts bit by bit according to the steam engine in his mind, and finally managed to piece together a miniature version of the steam train.

Although it looks rudimentary, the sparrow is small and well-equipped with all kinds of core parts. At least in Mo Zizai's opinion, it should be able to run.

The simple train is divided into two carriages. The steam engine is placed in the front carriage as the power to drive the whole small train, and the rear carriage is empty. Mo Zizai is ready to add loads to it depending on the situation. If all goes well, this can be used Test the maximum load of this little train.

In addition to these, Deng Zhi and the others felt that Mo Zizai had built too few rails, so they built a lot of them, connecting end to end to form a big circle in the yard. The tracks were forced to stop.

After finishing everything, Mo Zizai ignited the charcoal fire under the boiler with a sense of mission, and quietly waited for the steam train to run automatically.

"Master, do you think this thing can run?"

Regarding this steam train, Tao Qiong always felt that he had no idea, and Tao Qiong habitually consulted his master about the things he didn't know.

When Mo Zizai discussed the principle of the steam locomotive with Deng Zhi and the others before, Tao Qiong went to get the materials, so he didn't know much about this thing, and he didn't have much confidence in its ability to run.

He always felt a little unbelievable, how can there be something that can run by himself, even if there is steam, it is unrealistic.

"should be no problem."

Zhao Ran's face was a little serious. When Mo Zizai asked them to build something, he had already told them the principle of the steam train, so Zhao Ran and the others thought that this thing could run theoretically.

Seeing that Tao Qiong wanted to ask again, Zhao Ran interrupted him directly, "Don't talk nonsense, just watch carefully, if you have any questions, ask after reading."

"This thing is more important than you think. If it can run smoothly, the whole big week will usher in new changes."

Under the expectant eyes of Zhao Ran and the others, the water in the steam engine was completely boiled. Under the action of air pressure, the piston began to be slowly pushed, and the transmission rod was driven to drive the wheels forward.

At the beginning, the speed of the steam train was very slow, but as the air pressure became stronger and the pistons moved faster and faster, the train drove faster and faster.

"Woo~"

With a dull sound from the exhaust valve of the steam engine, the air pressure in the boiler officially reached its maximum value. At this time, the speed of the steam train was already faster than the running speed of an ordinary person.

"Can you really run?"

Watching the steam train making a 'woo-woo-woo' sound while speeding along the rails, Zhou Qi was filled with shock.

As a layman who doesn't know how to forge, when Mo Zizai explained the principle to Deng Zhi and the others, he basically didn't understand it, and he understood one sentence at the end.

That is, if this thing can run smoothly, it can still run after it is enlarged.

After zooming in, it can pull hundreds of thousands of stones, and it runs faster than a horse. The most important thing is that it doesn't need to eat or drink, as long as it has enough fuel, it can keep running.

"If this thing is used to transport troops or food, the army in the capital can reach the border overnight."

Zhou Qi looked at the steam train with fiery eyes. On the battlefield, speed is the most important thing in soldiers. What is super speed? This is super speed!
He couldn't even imagine how desperate the coach of the other side would be if one side suddenly had an army of 10,000+ when the two sides were fighting fiercely!

"My lord, this thing must be made!!!"

When Mo Zizai was observing whether there were any defects in the steam train, he suddenly heard Zhou Qi speak, and couldn't help being a little surprised, but when he saw Zhou Qi's excited expression, he probably understood what Zhou Qi was thinking.

"Don't worry, since the small ones can move, the big ones are fine."

"No, there is a problem."

Liu Xun stared at the steam train tightly, and Lao Gao frowned, "My lord, come and have a look."

When Liu Xun was observing before, he put a weight of about several hundred kilograms on the empty carriage behind the steam train. The steam train loaded with hundreds of kilograms only dropped slightly in speed and did not have much impact.

At first, several people thought that there was nothing wrong with the car, but when they heard Liu Xun said that there was a problem, they immediately gathered together.

"I said Liu Dapao, why didn't I see anything wrong? Are you talking nonsense?"

Deng Zhi took a closer look at the steam train that was still running smoothly, and didn't see any problems, so she subconsciously spoke to Liu Xun.

"Stop talking nonsense, I didn't let you look at the car, look at the stove, there is something wrong with the stove!"

Hearing Liu Xun talk about looking at the stove, since he subconsciously turned his gaze away, Tao Qiong asked a little unsurely after a while, "Is this stove a bit bigger?"

"It's not that it's a little bigger, it's that the top is bulging."

As an expert on being bombed, Liu Xun is quite clear about this situation, "This thing is going to be bombed!"

Hearing Liu Xun said that it was going to explode, Zhou Qi subconsciously stood in front of Mo Zizai.

"Bang~"

As soon as Liu Xun finished speaking, the steam train that was running at high speed suddenly made a loud noise, and the whole boiler exploded a big mouth, and the boiling water splashed all over the yard like a goddess scattering flowers.

"This...what's the matter?"

Zhou Qi stretched out his hand to catch a fragment of the boiler that splashed over, feeling a little hot in his hand.

"The pressure is too much for the boiler to handle."

This time, without Mo Zizi, Deng Zhi explained the problem, "The outer wall of the boiler we built is too thin to withstand such a large pressure. It is enough to thicken it when we go back to it."

"Thickening doesn't work either."

Liu Xun's brows were still furrowed, "It's a material problem. The iron boiler can't withstand such a high pressure. Unless you add it to a very thick layer, it will still explode after a long time."

Regarding the explosion, Liu Xun is undoubtedly the one who has the most say. If he says no, then it must not.

"If this is the case, then the only choice is to change the material."

Zhao Ran said slowly, "Ordinary fine iron won't work, so replace it with black iron."

"Mo Tie is fine, but in this way, only us old guys can build this thing."

Deng Zhi nodded and said: "Besides, according to what the lord said, this thing is not only a front, but also many carriages. These are all easy to say, the most important thing is the rails."

"For something with such a heavy burden, ordinary rails will definitely not work, and it must be made of black iron."

"And this thing is going to go to various places in Dazhou. Have you ever thought about how many rails are needed?"

"It's just a few of us old guys, even if we work hard to the death, it's hard to say whether the rails we made can get out of Tianjing City!"
