The most arrogant in history

Human emotions are very complicated.

Although Yu Guinong was not a good guy, at this moment, Ye Kun believed that he was expressing his true feelings.

After all, they have been together for nearly ten years, and there has never been a falling out between the king and his subjects.

"Master Yu, you are older than me and can be considered my teacher. If you are reluctant to leave, I will be reluctant to leave too." Ye Kun sighed and smiled.

"But for the future of the Chinese race, we must go out and control the Nanyang continent. If the Chinese continent is invaded by foreign races in the future, the overseas Chinese descendants must not forget to lead a million strong army back to the homeland and restore the Chinese clothing!"

Yu Guinong nodded repeatedly: "I will warn my descendants that even if it is ten thousand years later, when the nine provinces of China are in danger, the descendants of the Chinese people in the Nanyang Continent will definitely come across the ocean to fight the national crisis together!"

Ye Kun was very touched: "I am very comforted by your words."

Sang Buyi and others were standing nearby, all of them were moved.

He Kangju wiped his eyes and sighed, "It turns out that the emperor allowed the Huaxia people to expand and develop overseas, and there is such a deep meaning behind it..."

Ye Kun nodded: "Yes, I am worried that in the future, the surrounding alien races will rise up, slaughter our Chinese people, and destroy our Chinese clothing, so I let everyone expand overseas. Our current territory is large enough. Even if there are surrounding alien races that rise up in the future, it is impossible for them to sweep across the world and completely exterminate our Chinese bloodline and clothing!"

The current territory includes the entire Jiaozhi Peninsula and the Jizui Peninsula.

It will be impossible for any powerful alien race to completely occupy the area in the future.

Even the ferocious Yuan Mongolian cavalry failed to capture the entire Jiaozhi Peninsula.

After seeing Yu Guinong off, Ye Kun felt a little lost.

One reason is reluctance;

Another reason is that they are worried that the descendants of the Chinese people in Southeast Asia will retaliate against their homeland after they develop.

So, Ye Kun kept a trick up his sleeve.

Ye Kun provided most of the scientific and technological information and technical personnel that Yu Guinong asked for.

Including black powder technology and black powder-driven gun manufacturing technology.

However, Ye Kun did not give Guinong new gun and artillery technology and gunpowder technology.

According to common sense, it would take at least a hundred years for the Yu Guinong family to become powerful after traveling to Australia.

And a hundred years later, the nine provinces of China should be very developed relying on systematic technology.

Coupled with its population advantage and comprehensive strength, it will be many times ahead of the Australian Islands in the South Pacific.

Huang Ye came to report: "Your Majesty, Gongsun Shangfei, the son of the retired emperor Gongsun Zhang, has returned. He has written a letter requesting to see Your Majesty."

Ye Kun frowned: "Let him rest in the palace of the emperor for two days. Yu Guinong just left these two days. I am in a bad mood and will not meet him for the time being."

Huang Ye took the order and left.

Ye Kun also calmed down and went to the Science and Technology City to continue supervising various scientific research activities.

Pang Jia was very excited and reported: "Brother Emperor, you will definitely be satisfied with the bearings this time!"

"Really? Let me see!"

Ye Kun also became happy.

The latest manganese steel bearings are indeed very precise, and they are ball bearings, so there is no abnormal noise even at high-speed rotation.

It’s just that the bearing is relatively large, about the same size as the rim of a large bowl.

For this thing, the larger the specification, the more it can accommodate errors;

The smaller it is, the harder it is to control the precision.

Pang Jia continued to introduce: "We have put this thing through five days and five nights of non-stop high-speed testing, and we haven't seen any wear and tear so far. When tested on a steam engine, the service life is more than thirty-six hours."

"Great." Ye Kun nodded repeatedly:

"Bearings are the most important basic parts in industry. Once this barrier is overcome, we will enter an era of rapid development. With this thing, we can also build another steam engine called a 'steam bladeless turbine'. The structure of the turbine is even simpler than our current steam engine, but the speed is too fast and needs to be controlled."

Today's steam engines are of the stroke type.

Steam turbines are different. They do not have stroke motion and are similar to electric motors.

And the noise is also less.

This thing is perfect for making a water pump.

After listening to Ye Kun's introduction, Pang Jia was very excited and said with a smile: "Brother, there is such a good thing. Why didn't you tell me earlier? If you told me earlier, I would have made it now."

Ye Kun shook his head: "The speed of the steam turbine is very fast. Without qualified bearings, it is useless for me to give you the drawings. Let me take a look at the latest steam engine first, and then I will tell you the principle of the turbine when I have time."

Pang Jia nodded and accompanied Ye Kun to see the steam engine.

The service life of today's steam engines has increased several times, and they can provide stable power.

There is also the problem of sealing rings, and after continuous exploration and experimentation, great progress has been made.

He Tiantian said: "Your Majesty, our steam engine warship has been launched. Do you want to go and take a look?"

"Of course I have to go and see it."

Ye Kun smiled and said, "I have been waiting for this day for a long time."

He Tiantian ordered a carriage to take Ye Kun to see the warships on the Shengang Lake.

There are only two steam-powered warships now, which are used as experimental products.

The Shenzhen-Hong Kong Lake, which serves as a testing ground, was also specially built and is not far from the Science and Technology City.

In addition to steam-powered warships, there are also various types of ships here, all of which are experimental products of the Science and Technology City.

Pang Jia was playful and made a pedal boat, which was like a treadmill on the water. When people stepped on the pedals on the boat, the boat would move forward. There was no need for rowing, sails or oars.

There are also various kinds of paddle steamers powered by animals, which are strange and bizarre.

Ye Kun didn't know whether to laugh or cry at Pang Jia's "great achievement" and squinted his eyes and said, "Brother Pang Jia, I plan to set up a 'most useless' scientific invention award in the future. Most of the things you invented can win the award."

Pang Jia pretended to be confused: "Why, are my inventions all useless? I don't think so. At least, these inventions are fun, right?"

Ye Kun was too lazy to argue, so he boarded the steam warship and checked the engine room.

Due to technical problems, steam engines are relatively large, but their energy utilization rate is not high.

Pang Jia was worried that the warship was not fast enough, so he installed four steam engines to drive four paddle wheels.

In this way, the warship looks very strange, like a monster.

Ye Kun checked it and ordered the boat to set sail.

As the steam engine started, the warship moved forward.

Pang Jia drove the boat himself, constantly accelerating, and finally increased the speed to about 50 kilometers per hour.

Ye Kun nodded and confirmed the speed of the warship: "Without sails, 50 kilometers per hour is about right."

This is a paddle steamer and is very inefficient.

If it is replaced with a propeller warship, the speed can be further increased.

He Tiantian introduced the situation and took Ye Kun to see the propeller warship.

The warships here are manufactured according to practical standards and are prepared for mass production. They are the most advanced in terms of both appearance and speed performance.

Pang Jia drove the warship very fast, and said with a smile: "Brother Emperor, in another six months, our new warship will be launched to the sea. It will only take five days and five nights to get from Tianjin Port to Jiaozhi! It will only take ten days to reach the South Continent in the South Sea."
