"Oh! It turned out that it was the Glen Kingdom that was making trouble in the back, and it just so happened that the two of them would solve it together. ”

Liu Yuetian didn't take them seriously at all.

"That's the best, as long as we eliminate them, our Great Zhou will be completely free of external troubles."

Liu Che nodded yes.

"Big brother, although the land of our Great Zhou is vast, but the real world is far bigger than we imagined, it is just a matter of raising hands to solve the country of Gülen and the Russians, there must be more countries besides Gülen and Russia, what we want to do is to become the real overlord of the world, even if this country is tens of thousands of miles away, we must worship our Da Zhou."

"What? The true lord of the world? ”

Liu Yuetian's words shocked the audience.

How do they know how big the world is outside of the Great Zhou? Legend has it that the country of Gülen is more than 10,000 miles away from the Great Zhou, and such a distance feels like the edge of the sky, and now Liu Yuetian actually said that there are other countries besides the country of Gülan, which is beyond their cognition.

"What the Great General King said is right!"

At this time, Sun Quan on the side nodded and said.

"We have a lot of sailors there who go to sea, once they encounter wind and waves, some of them will die at the bottom of the sea, but there are also a small number of people who are blown out by the wind and waves and do not know how far, and they are displaced to some strange countries, and many of them have never been able to come back, but there are also some people who have returned to their hometowns after years, or even decades, and in their mouths, I have heard that some countries are thousands of miles away, and the customs there are completely different from our Great Zhou, and there are even people who say that the local residents are all black. It's unbelievable that you can't even distinguish faces at night. ”

"What King Wu said is extremely true, the sea is boundless, if you want to cross the ocean to reach the other side, even your building boat can't do it, but there is no problem with my dragon boat, I still have to build a lot of dragon boats, the largest can even put down hundreds of people, with dragon boats, no matter how big the wind and waves can't stop it."

"Okay, okay, I also want to see those strange countries, strange inhabitants, and I will build ships according to the orders of the great general when I return."

King Wu replied immediately.

"Everyone, the world is big, far from what you can imagine, so we all have to take a long-term view, we are all Central Plains people, with the same culture and the same bloodline, in the whole world, in fact, we are a family, what we have to do in the future is to spread our advanced culture and technology, so that everyone in the world recognizes our culture, at that time, we human beings are a family, there will be no more disputes and wars! This is my Liu Yuetian's dream! ”

It turned out that people didn't care about those princes at all, his dream was to conquer the real world, and Liu Yuetian's dream was enough for everyone to look up to.

Everyone soon returned to their territory, Cao Pi and Li Jing told their father and master what they saw and heard, Cao Cao and Li Shimin were still a little unconvinced, and sent a team of envoys to Chang'an again, but after going back, they still said the same thing: Can't beat it! There is no chance at all!

Finally, Cao Cao and Li Shimin could not sit still, and a few months later the two of them went to Chang'an in person, and when they saw the power of artillery and muskets with their own eyes, they immediately expressed their submission to Liu Che, and also asked Liu Che to provide them with these two weapons.

Liu Che was very arrogant, and gave each of them three cannons, plus two hundred muskets, and the reason why he would do this was because Liu Yuetian told him that according to the current level of science and technology, these two weapons could not be built by others for the time being, and it would take at least five or six years to make it possible, and after five or six years, he had already manufactured more advanced weapons.

The same is true of the Great Qin, who sent envoys to Chang'an many times, and a year later, the King of Qin finally came to Chang'an after more than a month of trekking through mountains and rivers, at this time there were already a hundred artillery pieces and 20,000 muskets in Chang'an, and in a volley of artillery that was enough to destroy the mountain peaks, the King of Qin lowered his proud head and knelt on the ground with the courtesy of a monarch and a minister.

Of course, he also asked Liu Che for two cannons and a hundred muskets, hoping to study it well when he went back, and Liu Che played it.

In the early spring of the second year of Tianyou, Liu Yuetian and Sun Shangxiang's first child was born, it was a girl, you must know that Liu Yuetian never married a wife in his previous life, and finally had a child in this life, he doted on this daughter very much, so that Sun Shangxiang was a little jealous.

In the third year of God's blessing, Sun Shangxiang gave birth to twins again, both of whom were boys, and the whole world was happy for Liu Yuetian.

In the past three years, the two cities of Hongnong and Tianshui have expanded frantically, the scale of the city can accommodate 2 million people, agriculture and commerce continue to develop, and Liu Yuetian has developed a steam engine as the power of sowing and harvesting machines, which can sow thousands of acres of land in one day, which greatly improves productivity.

The large number of residents moved in and the resources began to be scarce, especially the land, the original city simply could not accommodate so many people, and the city began to expand, doubling in just two years.

At the same time, the steam engine also began to develop to civilian, and the development of the steam engine was gradually carried out, especially those Mojia people, the theory of the Mojia family contains simple scientific principles, through the understanding of nature to manufacture various appliances, so their understanding of the principle of the steam engine is much stronger than ordinary people, in fact, the manufacture of the first generation of steam engines has their credit, and as Liu Yuetian taught them more theories, these people's ingenuity suddenly burst out, and the invention of gears is the most important step.

Of course, gears were the first to be invented by Liu Yuetian, but they were soon carried forward in the hands of the Mojiamen, and in just two years, the Mojiamen people applied the gears in many places.

The characteristic of the gear is to conduct power, and the use of the steam engine is undoubtedly a perfect match, for example, the power system of the fire dragon car was very simple in the past, the steam engine drove several linkage shafts to drive the steel wheel after pushing the piston, so the speed of the fire dragon car is not easy to control once it runs, and the speed can only be reduced by reducing the driving force of the steam engine, and after adding gears, people can guide the thrust to other places, such as adding a trebuchet to the fire dragon car, and the vehicle can attack while traveling.

Of course, the biggest role of gear is to roll pig iron, the huge force generated by steam will be rolled into real steel, with steel, a large number of machinery can be born in a steady stream, and even without Liu Yuetian, the wisdom of the general public can continue to manufacture machinery useful to them.

It can be said that as long as 10,000 people continue to study the steam engine, then the industrial age will come.

And Liu Yuetian, he has already begun to develop electricity.
