Because several masters are very strong, they are also very fast in building.

Not long after, a brand new boiler was re-launched. In addition to these boilers, there are also some messy parts.

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

Although it looks simple, although the sparrow is small and has all kinds of core parts, 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 driving force to drive the entire small train, and the carriage behind is empty. Mo Zizhai is ready to add weights to it according to the situation. If everything goes well, this can be used to test the maximum weight load of the small train.

In addition to these, Deng Zhi and the others also thought that Mo Zizai had built too few rails, and they built a lot of them, connecting the ends of the yard to form a large circle. In this way, once the steam train can run, it will not be forced to stop because there are no rails.

After everything was done, 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 away?"

Tao Qiong always felt unsure about this steam train, but Tao Qiong habitually consulted his master for the things he had unsure about.

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

He always felt a little incredible. There was nothing he could run away with. Even if there was steam, it was not realistic.

“It should be no problem.”

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

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

"This thing is more important than you think about. If it can run smoothly, the entire Great Zhou will usher in new changes."

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

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

“Woo~”

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

"Can you really run?"

Zhou Qi was filled with shock as he watched the steam train make a "whimper" sound while driving rapidly on the rails.

As an outsider who can't forge, when Mo Zizai talked to Deng Zhi and the others about the principle, he basically didn't understand it, and at the end he understood one.

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

After enlargement, it can pull hundreds of thousands of stones of things, and it runs faster than a horse. The most important thing is that it does not have to eat or drink. As long as there is enough fuel, it can run continuously.

"If you use this thing to transport troops or food and grass, the army in the capital will be able to reach the border overnight."

Zhou Qi's eyes were full of heat when he looked at the steam train. On the battlefield, the soldiers were of great importance to speed. What is speed? This is speed!

He could not even imagine how desperate the other side would be if the fierce battle between the two sides was in full swing, and one side suddenly had more than 100,000 troops!

"Prince, 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 but feel a little surprised. When he saw Zhou Qi's excited expression on his face, he probably understood what Zhou Qi was thinking.

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

"No, there's something wrong."

Liu Xun stared at the steam train with his eyes tightly, and his brows frowned, "Prince, come and see."

While observing, Liu Xun put about a few hundred kilograms of heavy objects on the empty car behind the steam train, and loaded several hundred kilograms of steam train. The speed only dropped slightly and did not have much impact.

Originally, several people thought there was nothing wrong with the car, but when they heard Liu Xun say something was wrong, several people came over instantly.

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

Deng Zhi carefully observed the steam train that was still running smoothly, but did not see any problems. She subconsciously replied to Liu Xun.

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

After hearing Liu Xun's look at the stove, since he subconsciously turned his eyes over, after a while, Tao Qiong asked with some disconfidence: "Is this stove a little bigger?"

"It's not that it's a little bigger, it's because it's bulging."

As an expert who was bombed, Liu Xun was quite clear about this situation, "This thing is going to explode!"

When Zhou Qi heard Liu Xun say that it was going to explode, he subconsciously blocked Mo Zizai's face.

"Bang~"

As soon as Liu Xun finished speaking, the steam train that was driving rapidly made a loud noise. The entire boiler suddenly exploded into a big mouth. The boiling water was like a scattered flower in the sky, splashing the entire yard.

"This...what's going on?"

Zhou Qi reached out to catch a splashing piece of boiler fragment, and felt a little hot on his hands.

"The pressure is too high, and the boiler can't bear it."

This time, without Mo Zizai's words, Deng Zhi said the problem, "The outer wall of the boiler we built is too thin and cannot withstand such a great pressure. Just thicken it when you go back and make it."

“It’s not OK to thicken it.”

Liu Xun's brows were still frowning, "It's a matter of material. The iron boiler can't withstand such a lot of pressure. Unless you add it to a very thick one, it will still explode over time."

Regarding the explosion, Liu Xun is undoubtedly the one with the most say. He said no, then it must not be possible.

"If that's the case, then you'll have to change the materials."

Zhao Ran said slowly, "Ordinary fine iron cannot work, so just change to ink iron."

"Mo Tie is OK, but in this way, we are the old guys who can create this thing."

Deng Zhi nodded and said, "And, according to the prince, this thing is not just a front of the car, but also many carriages. These are easy to say, the most important thing is the rails."

"Ordinary railway tracks must not work if the burden is such a heavy thing, and they must also be made of ink iron."

"And this thing is going to travel all over the Great Zhou Dynasty. Have you ever thought about how many rails are needed in total?"
