A week later, Xianyang Palace, Qilin Palace!

"What do you think, Prince, of the purpose of the envoys from Rome and Carthage?"

Ying Zheng put down the credentials of the two countries sent by the Customs Department, looked at Ying Yu with a smile and asked.

"The two countries sent envoys this time just to find out the truth and see if they can get some benefits!"

Ying Yu said calmly.

"What His Royal Highness the Crown Prince said is reasonable. I think it would be better to refuse the visit of the envoys from these two countries. I can't let them see my Great Qin's artifact."

Dunruo immediately frowned and said.

"Why stop it? These railways and steam locomotives are not something they can learn by just looking at them."

"Let them see the power of the train with their own eyes, and it may have better effects."

Ying Yu smiled slightly.

Qin people have a habit of hiding good things, which is the so-called wealth should not be revealed.

This is indeed not a problem for some technologies that are easy for foreigners to learn, such as Quyuan plow, sugar craft, etc.

But for truly cutting-edge technology, you can’t figure it out just by looking at it.

You can learn it just by looking at the appearance, and it's not even as in-depth as Ying Yu's steam engine introduction published in Daqin Daily.

The reason why Ying Yu dared to do this was not only to let more people in Da Qin understand the role of science and engineering, but also to let the world know the technical content involved.

The principle of the steam engine is indeed very simple. It is nothing more than boiling water and using the power of water vapor.

It seems simple, but just a sealing problem can trouble all countries except Daqin.

Without rubber and corresponding processing technology, it is impossible to achieve air tightness under high temperatures.

The air tightness cannot be achieved, steam leaks out, and the steam engine with low thermal efficiency cannot be practical at all.

At most, it's just a large kettle, just listen to it.

After fixing the air tightness of the steam engine, how to drive it and utilize the energy is not a simple matter.

Not only does it require sufficient research on mechanics and physics, but the requirements for materials are also extremely high.

If the material is slightly inferior, it cannot withstand the strong impact and will be crushed into powder.

And it’s not just strength. Many components must have both strength and toughness, otherwise they won’t be able to be used for a long time.

In addition, it must be able to withstand corrosion under high temperature and high pressure, not be too heavy, etc.

In order to build Daqin's first steam locomotive, Ying Yu had to bite the bullet and spend nearly 100 million reputation points to purchase a batch of equipment directly from the system mall. This made Daqin Engineering Institute's research and development and manufacturing have a lot of achievements.

progress.

This is true for the scientific researchers of the Great Qin Academy of Engineering, who are far ahead of other countries. Outside of Great Qin, the envoys of Rome and Carthage, who have no scientific concepts, can't possibly see anything from the outside.

Let them witness that bringing back Rome and Carthage through their mouths will be extremely helpful to Qin's next strategy.

When the Mediterranean countries suffered from locust plagues and purchased grain from Da Qin, the "grain supervisors" placed by Da Qin in various countries had gradually gained considerable influence in various countries.

But after all, the time is very short, and some conditions are needed to fully control the fishing boat.

And nothing can be more convincing in both countries than the personal confirmation from the envoys of the two countries.

Letting the people of the two countries realize the gap between them and Da Qin will be of great help to Da Qin's cultural colonization and future occupation.

Even countries as developed as later generations have various theories of leading the way, let alone Rome and Carthage, which are now suffering from constant wars and it is no exaggeration to describe the people as having a hard time.

Moreover, the bonds issued by the two countries, imitating the Qin Dynasty, will soon reach the time to repay the principal.

At that time, many unfavorable factors will erupt together, and it will be difficult for both countries to avoid chaos.

The more internal chaos there is, the greater the loss of population in both countries will be.

And population is one of the core factors that will determine whether Great Qin can completely control the Mediterranean in the future.

"Although this plan is a bit cruel, it is indeed the best way to control the Mediterranean!"

"What Daqin needs to do now is to stabilize its development and then wait for the opening of the Suez Canal."

"Even the Suez Canal, there is no need to rush to open it."

After listening to Ying Yu's introduction, Ying Zheng thought for a long time and then slowly spoke.

Wang Zhi and others also nodded repeatedly.

Military generals do not have so many concepts of the Holy Mother, and there are never so many rules and regulations on the battlefield.

Kindness to the enemy is cruelty to oneself.

Although Nei Shiteng and other civil servants may not be as decisive as the generals, no one is stupid enough to speak out against it.

This kind of intercession for foreigners is definitely an act seeking death.

And if we want long-term peace and stability, the Qin people must have an absolute advantage.

It is better for the two countries to reduce their population by themselves now than for Great Qin to do it in the future.

"By the way, how are the preparations for the Xianyang to Luoyang railway going now?"

Ying Zheng glanced around the court, took in everyone's reactions, nodded with satisfaction, and then spoke.

"In addition to the extremely laborious opening of the tunnel, many of the railways in other areas have used the original roadbed of Qinzhi Road, so the progress is quite good."

"It is expected that in another month, the first section of the railway, which is about 60 miles from Xianyang City to Qinling Mountains, will be completed."

"By then, Daqin's first steam locomotive will be almost ready to be manufactured and put into trial operation."

Even with the aid of gunpowder, it is still not easy to dig a tunnel in the Qinling Mountains that can pass trains.

However, the laying of the roadbed in the flat areas, as well as the laying of rails and sleepers, went quite smoothly.

Therefore, Ying Yu simply asked the Engineering Academy and the construction unit to lay the first short section of railway from Xianyang City to Qinling Mountains first, and focused on the manufacture of steam locomotives.

At that time, while excavating the tunnel, we can use the already laid rails to test and improve the steam locomotives, and train train drivers at the same time.

After the tunnel is opened, all that is required is to continue extending the rails outwards.

"Then I'll be waiting for your good news."

A look of anticipation suddenly appeared on Ying Zheng's face.

Ever since he heard about the train, Ying Zheng has been yearning for it.

I originally thought that such a huge project would take at least one or two years to complete.

Now I actually learned from Ying Yu that we only need to wait another month before we can see the actual train.

This is definitely a great surprise.

Even with Ying Zheng's determination, he didn't show any joy on his face.

The courtiers are all looking forward to it.

At the same time, I was filled with emotions.
Chapter completed!
