Mo Zheng and Da Lao Chen immediately protected the van.

This stuff couldn't be better. It cannot be destroyed.

"Teacher, if this car can move, how fast will it be?" Hu Deyong asked.

Yan Ming silently calculated and said: "If the roads are smooth and intact, they are all cement paved, and they can be driven to Chang'an in one day." ”

"So fast?" Hu Deyong was shocked, but he immediately understood that what the teacher said was that the road was intact and the cement was paved.

Nowadays, the roads in and around the New Taipei City are paved with cement, and even the oil residue left over from oil refining is mixed with gravel paving, and the road surface is very intact and resistant to wind and rain.

But if you want to pave such a road between New Taipei City and Chang'an, it will be too difficult.

Hu Deyong voiced his doubts.

Yan Ming said: "Therefore, there need to be people like you who know how to construct in all the cities and villages of my Han Dynasty." In this way, roads began to be built in every city and village. In a few years, all the roads in my Dahan will be connected to form a transportation network. ”

Hu Deyong couldn't imagine what kind of picture it was. He's only staggered.

After a while, he sighed and said, "I finally know why teachers have to implement compulsory education throughout the country." ”

……

Mo Zheng and Da Lao Chen's main work during this period of time was to study the structure of the van.

Yan Ming took a group of children from the north and began to study the knowledge of ships on the artificial lake.

There were two shipbuilding experts on the side of Chang'an City.

Yan Ming was entertained with delicious food and drink.

The two of them worked very hard, and according to Yan Ming's requirements and proportions, the ship of the Han Dynasty was transformed and reduced into a small warship that could only carry a few people.

Yan Ming did not propose to build a building ship or even an iron ship, but first had to understand the power system of the ship.

After the model of the boat was built, it was the work of the elder Chen and them to transplant the power system.

An engine with gasoline is obviously not very realistic yet.

Today's engines are only removed from vans.

They don't yet have the machining tools to make the perfect engine.

Therefore, everything is still with a relatively backward steam engine.

When Da Lao Chen combined the steam engine system with the ship, it was the first test voyage.

A soldier who is good at swimming learns how to handle and use the ship's power system under the guidance of the elders Chen and Mo Zheng.

Yan Ming watched all this indifferently on the shore.

Although he was very calm, he was very excited in his heart. If this system test is successful, it will be a qualitative leap for Dahan.

Everything was ready, and the fuel added to the steam engine was also oil residue and coal.

With the accumulation of heat energy, the steam engine emits the sound of power transmission.

"Whew!" As the ship vented, the shrunken warship slowly sailed off shore. The muzzle velocity is not much faster than that of a human-powered ship.

Han Yan and the others gathered around the shore were already cheering.

In their opinion, as long as this thing can sail without human power, it is already a divine object.

As the steam engine became more and more rounded, the speed of the ship became faster and faster, leaving a trail of white waves on the surface of the lake, drifting away in both directions.

The soldier who controlled the ship had never sailed such a fast boat, and his heart was excited and scared at this time.

He steered the rudder of the ship, and with a slow spin, the ferry headed for the shore.

The shipbuilding experts from Chang'an were shocked by this meeting.

The two of them never dreamed that the boat they built would be able to go so fast.

The two of them suddenly had a word in their minds: "Great Voyage".

Before they came, Liu Che had personally summoned them, saying that he would go to the north to help Yan Ming and complete the first step of the Han Dynasty's dream of great navigation.

Now, they can already imagine what such a clipper looks like at sea.

The two of them hugged each other and cried, even more excited than Yan Ming.

At this time, Yan Ming saw that the ship was sailing steadily, but he lost his previous apprehension and excitement, and let out a sigh of indifference, leaving from the crowd cheering on the shore.

Han Yan saw Yan Ming leaving, and also followed closely behind Yan Ming.

"This thing is ingenious." Han Yan said.

Yan Ming smiled and said, "Not really." ”

"When you came back, you told me about the Great Voyage. Has His Majesty the Emperor decided to make a great voyage? Han Yan asked.

Yan Ming nodded.

Although Liu Che has not yet made up his mind to sail. But he believed that as long as he sent a sailing ship to cruise around the sea according to his words, Liu Che would arouse his determination to sail.

Water is the source of life, and life is said to come from the sea, and it will eventually return to the sea.

Conquest of the sea is the dream of mankind.

Yan Ming didn't think about it so much, he just wanted to rely on his ability to leave a trace of knowledge for Dahan.

Although he didn't have much time to teach, he went all out to promote compulsory education. As a result of this, in the near future, the Han Dynasty will have a large number of people entering science.

The strength of the Han Dynasty will inevitably come.

Before Liu Che's voyage and the end of the round-the-world voyage, what Yan Ming had to do was to pave the way and help the Han to be as strong as possible.

He wants to build a network of roads, a network of railways throughout the country.

If the steam engine is applied to ships, it can be applied to trains.

There are also things like hydropower, thermal power, etc., which must be improved.

After the beginning of the industrial revolution, it was the follow-up of various technologies. There are some things that Yan Ming doesn't understand very well, but fortunately, there are a large number of people from the Mo family around him, and there are many smart children who study with him.

He believes that Dahan is not short of talents. It's just that the eye for spotting talent is missing.

Now, what Yan Ming has to do is to let Liu Che mobilize the power of the whole country to engage in production.

Only when production is carried out can it be possible to carry out the next plan.

Once the circumnavigation is confirmed, with Liu Che's strength, he will definitely find a way to plunder the world.

Most of the Western countries are backward slave societies.

On the current land of Europe, it should be the beginning of Rome's domination of the world.

In later generations, some people have speculated countless times that when the Han Dynasty and Rome collided, who was stronger?

Yan Ming wanted to feel the collision between the Han Dynasty and Rome with practical actions.

Before colliding, Yan Ming would arm the Han Dynasty's army to the teeth.

And this kind of armament will start from New Taipei City.

The old industrial base in Northeast China, this is not in vain.

Yan Ming wrote the steam-powered ship experiment in detail. Report to Liu Che.

When Liu Che received the recital, he didn't sleep all night.

He wanted to see with his own eyes ships that sailed not on manpower and wind, but on their own power.

Liu Che, as one of the few grand strategic emperors in Chinese history, understood the importance of such ships. Once it is true, then the Age of Discovery is really coming.
