Reborn in the Water Margin as emperor, built tanks to level the world

Just like this, Zhao Ji was lying on the dragon table in the Shangshu room, holding half a charcoal pencil in one hand and pressing one side of the rice paper on the dragon table with the other hand.

He frowned and pondered for a long time before slowly starting to draw.

At first, Zhao Ji just sketched the rough outline of an old-fashioned green leather train on rice paper with charcoal.

Then, relying on the memories in his mind, he roughly drew the wheels and transmission mechanism of that kind of train.

Although Zhao Ji himself graduated from the Department of Mechanical Engineering in his previous life.

But I have never studied the structure of the green train.

That's why the speed of painting at this time is so slow.

It wasn't until late that night that Zhao Ji was able to draw the preliminary structural diagram of the green leather train.

As for some more details, Zhao Ji couldn't figure it out no matter what.

However, there is nothing to be afraid of.

Because there are also many officials from the Ministry of Industry who are providing technical support for this train.

When those officials from the Ministry of Industry were doing technical research for this green train.

Just ask yourself from the side.

Just like building those tanks and chariots before this.

After the morning court ended the next day, Zhao Ji called Shen Kuo, the minister of the Ministry of Industry, to the minister's study room.

Moreover, he also showed him the sketch of the green leather car that he had drawn last night.

When Shen Kuo saw the drawing, he was stunned for a moment, then frowned tightly.

After pondering for a long time:

"Guan, is this another combat vehicle of some kind?"

"But why, why can't we see any gun barrel?"

Zhao Ji shook his head with a smile on his face:

"Such things are not used to fight the enemy, but to pull goods and carry people."

"The green box at the front of the drawing is the main traction force of the entire vehicle."

"As for the car bodies located one by one at the rear and connected in series, their traveling power is provided by the front of the car."

"When the time comes, if we can improve the front of the car, let it run faster and faster."

"Then correspondingly, the dozens of car bodies behind will be pulled faster and faster."

"As long as the traction force of the front of the car is large enough, we can hang several car bodies, dozens of car bodies, or even dozens of car bodies behind the front of the car."

"And each car body can be divided into two types according to its shape: those for pulling people and those for carrying things."

"In the past, we used to transport goods within our Song Dynasty, or carry people somewhere."

"Usually, horse-drawn carriages, ox-carts, etc. are used to provide traction."

"This method of operation is not only extremely inefficient, but may also be robbed by bandits and strongmen along the way."

"But what if after this, this method of transportation is used throughout the Song Dynasty?"

“Not only will the delivery efficiency be greatly improved, but many unexpected situations will also be avoided.”

"When the time comes, whether we use this thing to transport troops and horses, transport battlefield supplies, or carry ordinary people of our Song Dynasty to other places."

“It will get twice the result with half the effort, fast and stable.”

After Shen Kuo listened to Zhao Ji's story, it seemed as if a door to a new world had been opened for him.

Because before this, he had never thought that the application range of steam power engines would be so wide.

It can actually be applied in this field.

And what about himself?

But he is also an extremely smart person. After Zhao Ji just did that, he immediately clearly realized in his heart the role and value of this kind of pragmatism in the future.

So at this time, many thought-provoking questions were raised:

"Officials, the things designed by the officials today are indeed of great benefit."

"But I don't know if the officials have thought about it if the entire structure of such a large car is made of steel."

"The weight must be huge."

"Even then, this so-called front traction force is large enough to pull a dozen or even dozens of car bodies, traveling like flying."

"Then the ground in our Song Dynasty may not be able to withstand it."

"You know, in our Song Dynasty, there are very few roads paved with gravel, even like our main roads in Tokyo."

“What’s more, it’s a road that can accommodate such a large vehicle.”

"And according to Wei Chen, even if it is as solid as the main road in Tokyo City, it is paved with gravel."

"This kind of car may not be able to run."

"If the cross section of the wheel is made as narrow as the official painting."

"Then it won't take long for the wheel surface to become deeply embedded in the gravel, making it difficult to move smoothly."

"As for other roads on the borders of the Song Dynasty, they are mainly made of sand and gravel."

"If that's the case, how can you run up there?"

Zhao Ji smiled and nodded:

"Actually, I thought of this a long time ago."

"Look at the back of this drawing."

As Zhao Ji said that, he turned over the drawing of the green leather train to the back.

What is drawn on the back is a design of an ordinary railway track.

Up there, there are not only two parallel railroad tracks.

Below it, there are sleepers made of cement and countless gravels on both sides:

"Shen Aiqing, as long as there is this kind of steel track, the kind of steel vehicles we were talking about before can travel on it without any hindrance."

"This kind of steel vehicle is not only extremely versatile, but also of great significance to the future construction and people's livelihood of our Song Dynasty."

"So Shen Aiqing, you now need to allocate a small group of officials from the Ministry of Industry to study this kind of vehicle day and night."

"If conditions permit, it would be best to build a prototype vehicle and test run it in the shortest possible time."

"If the effect is good, then report it to me."

"If I feel good here, then your Ministry of Industry can officially start manufacturing."

Shen Kuo's hands held the construction drawing tightly.

While watching, he nodded excitedly:

"Officials, if you want ministers to come and see something like this, given the current capabilities of the Ministry of Industry of the Song Dynasty, it can be made."

"It's just a matter of time."

"Officials, please rest assured. Weicheng will work hard with his subordinates to study this kind of steel vehicle so that it can be manufactured as soon as possible and presented to His Majesty for viewing."

Zhao Ji looked at Shen Kuo's back as he hurried away with the drawing.

I couldn't help but think about a lot.

At that moment, it was like seeing the prosperous scene of the Song Dynasty in the future, with several trains running parallel on the territory of the Song Dynasty.

Unknowingly, there were more emotions in my heart:

I think back to when I traveled from that world to this one.
