prosperous national teacher

While Su Yi was busy, coolies came, no, Yi Ran came.

As soon as Yi Ran came, Su Yi took Yi Ran to study mathematics.

Yi Ran was dumbfounded.

Although Yi Ran knew that Su Yi was compiling the book before he came, he also thought that although the emperor gave him a task, he would definitely help Su Yi coordinate the compilation of the book.Yi Ran is quite familiar with this kind of coordination and overall work.It's just that he didn't expect that the first thing he came here was not to do things, but to go to school.

Yi Ran has a powerful force and can hunt tigers with the help of guards at a young age.He is also very capable of dealing with affairs, but he is unreasonable, which makes some ministers in the court hate him.But Yi Ran's mathematical ability is not the same as that of Mu Yan, and she is also a person who can only apply formulas directly, and can't turn a corner.

Su Yi was heartbroken.

The only thing that comforted him was the correspondence with the prince, who was very sensitive to mathematics and had a strong learning ability.Su Yi thought, he deserves to be the younger brother he brought up, let him go!

After Yi Ran was forced by Su Yi to study for a while, she found an excuse to go to the boat and stay there.

That excuse was naturally the emperor's will.

Although Yi Ran wanted to stay with Su Yi very much, the charm of mathematics was too strong, so he ran away in a hurry.

Mu Yan was also busy with business, so he ended Su Yi's math class.

Su Yi pouted.Forget it, at least they memorized the formulas and examples, and he didn't ask for anything else.It's better to exchange math problems with his prince brother.

After Yi Ran came to the boat, she fell in love with the sea, and from then on she set her ambition on the sea...that was impossible.He got seasick.

Yi Ran had been on a boat in the river before, and did not notice seasickness.Who knew that once they got to the sea, they would be dizzy.

Mu Yan pretended to be regretful and said: "It seems that His Highness is not suitable for going to sea, so please ask Your Majesty, Your Highness should return to Beijing first?"

Yi Ran viciously poured down a bowl of bitter medicine, wiped her mouth, and said, "I can't bear this bit of bitterness, how can I explain to my father? Please also ask Master Mu to hide it for me for a while, so that I can get acquainted with it again. "

Mu Yan sighed: "Why bother, Your Highness? The sea is dangerous, and it's impossible for Your Highness to go to sea in person."

Yi Ran said: "That's not impossible. You can't go to far places, but you can go to nearby places. According to the national teacher, the world is vast, and I also want to see those places that have not been set foot. "

Mu Yan knew that he couldn't persuade him to leave, so he left with regret.

Su Yi has a thin skin, and Yi Ran eats and lives with Su Yi very unceremoniously.Although he can still share the bed with Su Yi at night, when Yi Ran is around during the day, Su Yi refuses to be too close to him.

He had always hoped that Yi Ran would leave quickly, but who knew that when Yi Ran was forced to leave by mathematics, he also ran away.

Now that Su Yi gave up teaching him two maths, Mu Yan would find time to be lazy at any time during the day, but Yi Ran came back to live again.

This brother-in-law is really annoying.

Su Yi agrees with Yi Ran's desire to overcome her seasickness.Su Yi has always wanted the people of the Hua Kingdom to pay more attention to the sea. If there is a prince who is willing to go to the sea in person to experience the charm of the sea, it will definitely help Hua Kingdom to pay attention to the sea.

The compilation of mathematics books is on the right track, and the road has to be taken step by step. Now that the first book is on the right track, Su Yi doesn't have to keep staring at it, so he also goes to the boat with Yi Ran to help Yi Ran train.

Su Yi used to go on an expedition to Goguryeo with a sea boat, so he was naturally not afraid of taking a sea boat.Su Yi thought of some modern methods of treating seasickness, and finally decided to let Yi Ran take the helm himself.

It's like a car sick person who doesn't get sick while driving, maybe Yi Ran won't get seasick if she concentrates on driving the boat?

I didn't expect this method to work.Yi Ran still gets dizzy when she is on a boat, but she really doesn't get dizzy when she is at the helm.

It appears that distraction is a useful form of therapy.

After Yi Ran learned how to drive a boat, she really liked the feeling of sailing on the sea.

Ever since Yi Ran dared to hunt tigers at a young age, she knew that Yi Ran was very courageous and liked to take risks.This may have something to do with his childhood.After his mother committed suicide, Yi Ran felt very depressed, and kept using exciting things to numb herself.But Yi Ran is a good boy, he can't do things to torment others - beating up playboys and former court officials who persuaded him to snatch the crown prince is not counted, so he can only torment himself.

Taking risks can make him forget his troubles.

Although there is no need to do this now, the risk-loving factor has penetrated into his heart.

What could be more exciting than navigating the waves in a big boat?Probably just fly the plane.

In the face of nature, human beings are so small.Looking at the overwhelming waves, the big boat is like a leaf floating on the water in the huge waves, as if it will be overturned if you are not careful.

Yi Ran became addicted to sailing.At first, he just practiced his sailing skills in the offshore, and then he drove farther and farther until he was stopped by Su Yi.

Yi Ran thought about it, when she told Mu Yan that she was going to sea, she just wanted to stay here and fight against Mu Yan.But now he really wanted to go to sea.

If it is far away, the father will definitely not agree.But I heard that there are many islands in the south, and those islands can also grow food, as well as spices and precious wood, maybe he can send an envoy to these small islands.

If there was a political power on the island, they would be very willing to submit to Yu Chao, a behemoth.If there is no political power on the island, then you can immigrate directly or build a supply base.

The idea of ​​the supply base was proposed by Su Yi.When the Mu family's first huge fleet returns with a full load, maritime trade will definitely rise. At that time, supply bases for the fleet will always be built along the route, and soldiers will also be deployed to go to sea at any time to escort the fleet away.

Otherwise, what if you encounter pirates?

If maritime trade really takes off, so-called supply bases must be built on the southern islands.While escorting the caravan, the army might be able to collect some protection fees.

Although the sea is a bit more difficult, but earn a lot.Moreover, the troops stationed at the supply base will be rotated at intervals, and they will not come back if they are not placed there.They must be willing to blow the sea breeze for a while and earn more money.

Yi Ran felt that she could be the vanguard.

Originally, Yi Ran's first job was to promote new crops.Now that the new crops have been harvested several times, and the resistance has been cleared away, there is no need for a prince to keep an eye on them all the time, so Yi Ran has already handed over the matter to the ministers of the DPRK and China.

Yi Ran had another important task before, which was to collect evidence that the vassal kings and aristocratic families colluded with the enemy, and now those vassal kings and aristocratic families have been executed.

The crown prince is now in charge of cultural and educational promotion, and the emperor has been thinking about what to do for Yi Ran, one of which is to be responsible for the opening of maritime trade.

Yi Ran felt that this suits him very well.

So Yi Ran told the emperor that he would lead the fleet south to find out where the supply base could be built.However, the emperor said that he would wait until the first batch of fleets returned.

Now the south is still a land of barbarians, and the people in the north are not suitable for the southern climate, thinking that the miasma in the south is heavy and they are easy to get sick.In fact, the humidity is too heavy and there are many mosquitoes.

The emperor was worried about letting his son go to that kind of place.

However, if maritime trade develops, the south may develop rapidly.

After Su Yi heard about it, he remembered the plight of the southern development at that time.

For roads, cement can solve it.Explosives can solve things like opening mountains.Miasma and so on, maybe he can come up with some medicine?Like penicillin?

Su Yi once cultivated and extracted penicillin in his own laboratory.This is actually not a difficult experiment, just need a microscope.

Now that the glass manufacturing process has broken through, colorless and transparent glass can already be produced. Although the output is not high, colorless and transparent glass must be used by Su Yi first.

Su Yi has already used it to make a telescope, and the telescope has been sent to various frontiers. Although it cannot become popular equipment for the army for the time being, at least the general will have one.

When Wang Boyuan returned to northern Xinjiang, Su Yi specially provided him with several telescopes.

As for the musket, Su Yi had already provided it to the emperor.The emperor is making weapons secretly.These weapons will definitely appear on the frontier in the future.

Before that, folks will open mountains and build roads, which may be used first.

Su Yi began to make simple microscopes.Although he once made a simple telescope by hand, the parts and components at that time were available for purchase, and the drawings can be downloaded from the Internet.

Now it is very difficult for Su Yi to manufacture microscopes through memory.

While Su Yi was tossing the microscope, he was also making a simple astronomical telescope.

He still remembered the promise he made with Mu Yan, to let Mu Yan see the real moon.

Because the telescope has been successful, the astronomical telescope is faster than the microscope.Of course, this has something to do with the fact that Su Yi made many simple astronomical telescopes for his nephews and nieces to play with, but he only made a microscope once, and then bought a high-end electron microscope.

He is more familiar with this.

After the astronomical telescope was completed, Su Yi kept his promise and took Mu Yan to see the moon on a full moon night.

As a result, that night, the yard was full of people queuing up to watch the moon.

Mu Yan felt a little bitter in his heart, where are the two people who agreed?

"They are all waiting for the astronomical telescope to be ready." Su Yi said that he was also helpless, "I can't refuse, right?"

Su Yi's heart is soft, and he can't stand other people's little eyes that look forward to pleading.Although he originally planned to see the moon with Mu Yan and then show it to these people, but for such a big event as the moon, everyone wants to be the first to see it.

If other people knew that Su Yi and Mu Yan wanted to be romantic, they might not follow them so shamelessly.But apparently they didn't know, they thought Mu Yan and Su Yi were just pure friends.

In the end, Mu Yan had no choice but to adjust his mentality.Anyway, I know that Su Yi made the astronomical telescope first to fulfill his promise, so that's fine.

Su Yi has seen the moon countless times, and he is already familiar with those potholes on the moon.But for these ancients, this is really a miracle.

When they saw the moon without fairy palace, Chang'e and laurel tree, they were very unhappy.Especially those who are quite romantic literati.

Su Yi can only talk nonsense, even if there is a fairy world, it is not the same interface as the human world.Even if ordinary people can go to the sky and enter the earth, they can't find the heavenly palace and the underworld.Otherwise, although people today cannot go to heaven, it is still no problem to dig a hole.Did they think that if they dug the pit deep enough, they would be able to dig into the underworld?

When everyone heard it, they suddenly felt polite.Even if there are fairy palaces and fairies on the moon, it shouldn't be the same world as them.So the so-called "moon" is just a human imagination. In fact, the fairyland and the human world should not be the same world.

Maybe Su Tianshi was able to go before, but now he can't go because of the common people.

"Then can we go there in the future?" If it wasn't for the image, Yi Ran really wanted to hold the binoculars and not let go.

That's what he saw from the telescope, but he was willing to keep watching.

The starry sky is so beautiful.

"When we go up here, it's the atmosphere. It's the clouds you see. Going up, thanks to the gravity of the earth, it's a vacuum. A vacuum doesn't have air. Without air, you can't breathe." Su Yi briefly introduced the planet and The concept of the universe makes these people dizzy.

However, Zhang Heng has already made an armillary sphere, and some scholars also know that the round sky is just a legend, and Zhang Heng's armillary sphere has been accepted by many scholars.Now they looked at the moon through the astronomical telescope, and agreed more with the statement that the earth is a ball.

What's more, this is what Su Tianshi said.

"Then can't we go?" Yi Ran regretted.

Su Yi said: "Of course I can go, but I can't go now. After thousands of years, people can create a machine that can fly in the sky. If the machine is fast enough, it can break through the gravity of the earth and enter space. If the fuel Enough, you can go to the moon. At that time, the spacecraft will be equipped with equipment that can produce oxygen...well, air, and people will be able to set foot on the moon's land wearing thick protective clothing."

"Perhaps thousands of years later, people's technology has developed again, and it will solve the current situation of no air on the moon, and it is also possible for people to move to the moon." Su Yi said, "People have dreams. Now our dream is The whole earth, we have to measure every inch of the earth with our footprints, and our ships have to sail every inch of the ocean. When we have completed the journey to the sea, the next step is the sky and the stars. Human dreams are endless of."

Listening to Su Yi's words, everyone suddenly felt very excited.

They never doubted Su Yi's words. Since Su Yi said that after thousands of years, human beings can walk on the land of the moon, it must be possible.

Although they are envious, as Su Yi said, the land they live in has not yet been measured clearly, so they can't aim too high.

"If the earth is a sphere, then if we move in one direction, will we return to the origin?" Mu Yan asked.

Su Yi said: "I once said, of course it is possible. It is too difficult to travel on this land, and you can sail through the sea. But because the distance is far away, it is very dangerous. If you want to complete the circumnavigation, the people on the ship must be prepared to escape death. Prepare."

Although he may prepare as much as possible, and even draw a rough map of the world, no one knows what dangers he will encounter on the sea.

If his navigator in the west of the world hadn't been looking for "the land of gold everywhere in the east" and wanted to open up new routes, he wouldn't have done such a dangerous thing.

Just for scientific research, few people have such courage.It must be supported by sufficient interests.

Perhaps the New World of America is a good support for interests, but given their location, they don't need to sail all the way, as long as they go all the way east.If you set sail in summer and sail along the land bridge, the danger may not be too great.

After Su Yi explained, everyone sighed.They also know that in order to prove that the earth is spherical, it is really impossible to spend so much money.Every human life is precious.

"But the New World... I really want to go..." Yi Ran sighed.

"It's still a no-man's land." Su Yi said, "There is no country there, and you can claim territory if you go there."

Yi Ran felt even more envious.

"If that's the case, then when the fleet returns, maybe I can convince His Majesty to send the fleet to the east to look for it." Mu Yan said, "The vast and fertile land..."

Su Yi said: "There are still many minerals on it. Even if we don't send people to reclaim it, at least we can dig out the mines on that piece of land."

Several people nodded in unison, and even the Mo family agreed.

Since Su Yi has said that it is a land without owner, there will be no war.

There are actually indigenous peoples on the American continent, but with Huaguo's foreign policy, as long as they don't attack the people they send to land, Huaguo will not go to war with them.America is so big that they can enclose land that no one has planted.As for minerals, if there is no political power in that place, there will be no demand for minerals.

Moreover, the people of Huaguo settled down and relocated. Unless there was an emergency, the possibility of large-scale emigration of the people to the American continent to reclaim the land and conflict with the local natives was very low.

After all, not every nation is like those "adventurers" in the West who treat people from different places as human beings.

However, if outsiders land on the American continent, even if they do not take the initiative to conflict with the local people, it may be a disaster for the local people.

Because of the virus carried by the landers, the local aborigines did not have antibodies.

And it is equally dangerous for the new arrivals.

It can only be said that the positions are still different.America cannot remain isolated from the rest of the world forever.

Su Yi believes that being the first to be discovered by Hua Guo must be better than his world.At least the Chinese people can't do the cruel thing of promulgating genocide laws and exchanging the scalps of the aborigines for money.

Huaguo Dynasty wanted to pay attention to word of mouth, if it did something too cruel, the ministers of the court and the central government would bump into the pillar.Some pedantic ministers would even criticize soldiers for killing too many people in war, let alone massacre civilians.

Su Yi ignited the fire of exploring the world in everyone's hearts. Even if this fire cannot be ignited now, but word of mouth will pass on, there will always be people who are interested in completing the unfinished feats of the predecessors.

． ． ． ． ． ． ． ． ． ． ． ． ． ． ． ． ． ． ． ． ． ． ． ． ． ． ． ． ． ．

The emperor and prince also knew about Su Yi's making of the astronomical telescope.

The emperor and the prince jumped anxiously, they also wanted to see the moon.But the astronomical telescope was expensive, and if others shipped it back, they were worried that it would be broken.And it's just boring to watch, Su Yi needs to explain it.

Coincidentally, it happened to be the emperor's birthday. The emperor hadn't celebrated his birthday for several years. This year, the weather was smooth, the frontiers were fine, and the court was peaceful. The emperor finally felt in the mood to celebrate his birthday.

So taking this opportunity, the emperor summoned Su Yi to come back with his astronomical telescope.

As a magistrate, Mu Yan is busy during this time, so he can't go back to Beijing together.Although Mu Yan was very reluctant, he knew Su Yi's true identity.The emperor must be looking forward to Su Yi returning to Beijing to celebrate his birthday, and so is Su Yi himself.

What's more, the palace is very curious about the astronomical telescope, and the emperor has already sent some urgent orders to urge Su Yi to return to Beijing soon.

So Su Yi took his astronomical telescope and set off first.

Yi Ran originally wanted to go with Su Yi, but he wanted to collect some birthday gifts and had to make a detour, so he didn't go with Su Yi.

But now the Yu Dynasty is very stable, the feudal lords and disobedient families have died, and Su Yi is returning to Beijing under the banner of a national teacher, the rest of the people are not worried about Su Yi's safety.

Mu Yan specially sent a team of cronies to accompany him. If he really encounters a bandit who doesn't have long eyes, he can also protect Su Yi's safety.

However, Su Yi didn't want to be too ostentatious, so it was still light and simple.Along the way, Su Yi continued to decline requests from local officials to see him.

Just keep rejecting, or people keep coming, it's really annoying.

So Su Yi tried his best to change the land route to the water route, and the accommodation was also on the boat, and he did not disembark for anything, and tried to avoid contact with outsiders as much as possible, so he became quieter.

When he had nothing to do, Su Yi would stop the fleet, and with one or two attendants, he would drive a flat boat and fish on the river where the fleet could see.

Although basically nothing can be caught.

Su Yi just felt that he was in a hurry before and didn't take a good look at the scenery.There was no rush to return to Beijing this time (Emperor: I am in a hurry!), and the road was safe, so he started to travel, taking a good look at the scenery along the way without deviating from the route.

The people on the road took Su Yi's orders first, and if Su Yi said there was no hurry, they were not in any hurry.

Even if officials go to work, if they leave early and there is no urgent matter, they will go all the way for fun.

Su Yi is already very worry-free, he basically does not deviate from the route.Only occasionally for a day or two.

So slowly, Su Yi and his party are about to enter the territory under the jurisdiction of the capital.

When he first entered the boundary of the capital, Su Yi heard from the accompanying people that there was a temple on a mountain nearby that was very effective, and Su Zhai was famous far and wide.

Of course Su Yi would not ask for a lottery, but he was a bit greedy.

Su Yi thought to himself, now that he has entered the border of Beijing, it doesn't matter even if he deviates from the route a little.He prepared to take a detour and go to the mountain in disguise to have a delicious vegetarian meal.It's not an overnight stay, he thought, it should be fine.

To put it bluntly, he was just hungry.

In order not to reveal his identity, Su Yi left some people waiting in the small town at the foot of the mountain, and only brought a few guards up the mountain.It's just a meal, but half a day.
