Northern Song Dynasty: Starting from the son of Song Renzong

Chapter 336 Achieved
The sixty-third year of the Li Yuan Dynasty.

Japan, east coast.

Once the ship set sail, there was nothing left for Zhao Xin to do.

All we can do now is wait for news of their return.

However, if they are coming back, their landing point will probably be around Taiwan or Xiaosong Island.

This is the answer obtained after various measurements and calculations.

But let’s be honest.

Although the Japanese women are good-looking and their dressing style is beginning to have some Song Dynasty style.

It's pleasing to the eye.

But supplies are scarce here, not as good as Zhao Xin's in Srivijaya and India.

In Srivijaya, in India, Zhao Xin could at least enjoy freedom of fruit, beef, mutton and pork.

Here, we can only eat tofu and fish. Of course, no matter where the Chinese go, they will definitely develop more dishes.

Some fried foods, for example, are starting to become more common here.

only……

Compared to other places, it is still much worse.

therefore……

After considering these two factors, Zhao Xin decided not to stay in Japan for long.

Several months after the ship set sail, Zhao Xin proposed to Zhao Xi the idea of ​​returning to the Song Dynasty.

Zhao Xi also led all the Japanese ministers and watched Zhao Xin leave.

When Zhao Xin returned to Xuchang, it was already the end of the year.

Then...

Zhao Xin also made the overseas information public to everyone in the Academy of Sciences.

By the way...

Make another copy and send it to Youzhou.

In fact, in today's Song Dynasty, Zhao Zhe no longer has much to do with affairs.

Maybe he was influenced by Zhao Xin.

and so……

Political affairs began to be handed over to the emperor's grandson.

of course!

Zhao Zhe also stated in the letter that if it was a letter from Zhao Xin, he would definitely read it personally, and if there was anything, he would let Zhao Li handle it personally.

Yelu Sager died only ten years ago.

Fortunately, Zhao Zhe did not favor other concubines too much because of Yelu Saguzhi's death.

Therefore, nothing has happened yet that could shake the country's foundation.

After returning to Xuchang, Zhao Xin continued to work.

first……

It is to watch and browse the achievements in physics, chemistry, mathematics and other fields made by the Song Dynasty after he left for so many years.

Secondly...

Also see if there is anything else I can add.

For example, manned space technology.

Although it may not be possible now, Zhao Xin must give them a topic.

What is the ocean? The sea of ​​stars is their real goal.

and……

There are great advantages in developing manned space technology.

However, since we are talking about manned space technology, we have to mention radio.

To be honest, if you ask anyone on the street, 99.9999% of them will not know the specific principles of radio.

only……

This does not prevent Zhao Xin from taking this out separately and explaining it.

even……

Next, I worked with everyone to make the world's first carbon microphone in the Song Dynasty.

Although there is no rubber now, it does not mean that we cannot use some other things for insulation.

after all……

It's just a laboratory product.

With a carbon microphone, you also need a speaker.

Zhao Xin also invented the loudspeaker with everyone else.

But again, it is just a laboratory product now, and we can only say that it has been verified in principle and technical feasibility that it can be done.

But it is still far from being truly practical and commercialized.

For example, how can you mass-produce magnets? For example, how can you leave the wires exposed without being disturbed by the environment?

Also, how to improve sound quality, how to control volume and so on.

Regarding some things that had already appeared in the Song Dynasty, such as electric lights.

Zhao Xin also prompted him to make some improvements.

For example...

In the past, we used materials that would break when burned.

just now……

Zhao Xin could ask them to use bamboo fiber carbonization instead.

Since carbon can withstand high temperatures of 3550 degrees Celsius, it can be used as a wick for electric lamps.

can only say……

When the bamboo filament light bulb was made, everyone in the Academy of Sciences was dumbfounded.

If Zhao Xin could read minds, then these people would definitely think, "Damn it! How can you do this?"

of course!

The reason why Zhao Xin was able to achieve these achievements is inseparable from the fact that over the years, people in the Academy of Sciences have mastered the technology of power generation more proficiently.

Without this premise, Zhao Xin would be helpless.

finally……

After the experiment, the light bulb stayed lit for almost two months, and the filament burned out in less than two months.

Be reasonable!
If this is spread out, the candle will be ruined.

only……

The biggest problem today is that there is no reliable power transmission system.

And a relatively high-power power generation system.

and so……

Zhao Xin directly proposed hydropower, thermal power and wind power.

at the same time……

The working principle of the steam turbine generator was also briefly explained.

We also conducted an experiment on the working efficiency of the steam turbine.

And the vision for the future development of the Song Dynasty.

After taking Zhao Xin's class, the people in the Academy of Sciences looked at Zhao Xin with gazes that were filled with undisguised admiration.

After sharing this knowledge, Zhao Xin was also thinking.

Should we further expand the scope of dissemination of this knowledge?

after all……

There are several thousand to ten thousand people in the Academy of Sciences alone.

Definitely not enough.

and……

Quite a lot of them actually have no talent.

of course!

Zhao Xin won’t do it for now.

but……

He will pass this idea on to his descendants.

When what Zhao Xin said was passed on to Zhao Zhe and the emperor's grandson Zhao Lina.

Both of them were dumbfounded.

His father, his great grandfather, divided the history of the world into the Stone Age, the Bronze Age, the Iron Age, then the Steam Age, the Electrical Age, and finally the Information Age.

Every era has its own characteristics.

Every era has its own vested interests.

However, the Zhao family naturally has to be the initiator of every era and the final vested interest holder.

This requires the Zhao royal family to treat new knowledge, new technologies, and new applications as national strategic levels.

So many years have passed.

Although the scientific knowledge of the Song Dynasty has been repeatedly summarized, broken through and discovered.

But Zhao Xin didn't think they really took this seriously.

Exactly!

Zhao Xin can use this to urge them not to underestimate the power of science.

at the same time……

We also teach them to have a broad and global perspective.

Don't just focus on what's happening in Youzhou City. You have to find ways to understand the changes in this world.

For example, what is Srivijaya like, and what developments have taken place in recent years. If you can't go there in person, you can ask someone to draw some of the local customs and practices, and have an artist draw them.

A special realistic painting academy was established to paint the customs, developments and changes of the outside world.

Painting once a year is too frequent.

Then you can have someone paint it every three or five years.

Speaking of which...

Zhao Xin thought of taking pictures again.

then……

He then proposed the concept of photography to the people at the Academy of Sciences.

but……

This requires the use of chemical methods.

It's just a matter of luck to see who can invent it first.

in this way……

I lived in Xuchang for about half a year.

During this period, I also communicated with Chen Yuanyuan. Now it is much more convenient and I have more free time.

nature……

The exchange of letters became more frequent, and Zhao Xin was motivated to write.

Anyway...

Along the way, there were constant post horses and steam engines delivering messages.

Nowadays, most steam locomotives are used to transport food and other goods, but a small number are also used to transport people, run errands for people, deliver letters, and even send money and clothes.

These services were not proposed by Zhao Xin.

Rather, the Song Dynasty was relatively open and adept at financial management throughout China's ancient history.

When such a thing appeared, the scholars and officials in the court naturally thought that the railway could be operated in this way.

in fact……

If you really mean it, it is possible to lose money by operating a railway.

So if you don’t want to lose money but at the same time you can’t raise prices excessively, what should you do?
Naturally, related value-added services will definitely be invented.

nowadays……

The exchange of letters from Kaifeng to Youzhou is also very convenient. If nothing unexpected happens, basically, it can be delivered within five days for a one-way trip, and within ten days for a round trip.

Zhao Xin also made full use of this advantage.

He wrote to Chen Yuanyuan every few days.

It could be a humorous joke.

Or maybe it's just a shameless love talk.

After half a year, Chen Yuanyuan was already very excited.

No one knew who leaked the news, but even Chen Yuanyuan knew that he had two concubines in Zhu Luo.

then……

She became jealous.

Zhao Xin said that he had never touched them.

and……

That Zhu Luo, whether male or female, is all dark-skinned and it's impossible to kill them.

If you don't believe me, have someone send a Zhu Luo woman over some other day.

Chen Yuanyuan replied, why don’t you send your two concubines back?

Zhao Xin also replied, "You can think of it. It can prove my innocence."

In fact...

She wasn't really jealous.

She just wanted to cause trouble with Zhao Xin.

It was June of that year.

Little Song Island.

When a group of Koreans were farming on the plains, suddenly, a large ship appeared in their eyes.

of course!

The Koreans were not inexperienced people, but they were still quite surprised by the appearance of this large ship.

The news that someone had arrived on the island was quickly reported to Goryeo officials.

The officials immediately entertained him.

The people on this ship also felt quite friendly towards these Koreans.

I found someone who knows Chinese.

The two sides soon started talking.

only……

However, the group did not tell the other party that they had returned from America.

Just know that they all finally got back safely.

They hugged each other and cried.

soon……

The ship then arrived in Quanzhou again.

Immediately afterwards...

From Quanzhou, the news was reported to the court.

The court also conveyed this news to Zhao Xin.

One of their ships has returned from America!
Zhao Xin knew that as long as scientific methods were used, it would definitely be feasible.

In the memorial, they also reported what they brought back this time.

Of course, they are all transliterations of the local indigenous people.

However, Zhao Xin could still guess what they brought back from the description in the memorial.

There are corn, pumpkin, pepper, sweet potato, and all kinds of magical fruits that you have never seen before.

The crew also discussed planting techniques with the locals.

only……

I came back too hastily and didn't study it carefully.

But they left a ship there, established a permanent base there and learned the farming techniques of the locals.

Fortunately, the locals are quite friendly.

Currently, only trade is taking place between the two sides, and no major conflict has broken out immediately.

After learning about the situation, Zhao Xin rushed to Quanzhou from Xuchang.

By the way, some people from the Academy of Sciences were also brought out.

If you haven't made much progress in other scientific research, you might as well follow me to study how to scientifically plant and cultivate American crops.

When Zhao Xin arrived in Quanzhou, some of the seeds and other things on the ship had gone bad.

This is due to improper storage.

Fortunately, a considerable portion of it has been preserved.

Zhao Xin then dealt with these things based on some scattered knowledge he had learned from the crew and the locals.

What crops can be planted in the next period of time.

This can be prepared immediately.

In order to better grasp the planting time of these things, someone needs to stay in America for at least two or three years.

This is also the reason why only one ship returned in the end.

of course!

In fact, common sense tells us so.

Generally, crops are planted either in spring or after the autumn harvest.

Rotate with other crops.

A few crops can also be grown in summer and winter.

only……

There may be more pests and diseases, and the yield is difficult to guarantee, and the taste may not be as good as that grown in spring and autumn.

Zhao Xin then also drew a test garden in Quanzhou to conduct experiments.

at the same time……

Generous rewards were given to those who returned, those who died on the way, and those who were still in America and their families.

Of course!
The money for this generous reward must have been paid by the Song Dynasty court.

On the way...

I can only say that we encountered some bad weather, but overall, the whole journey was safe and sound.

Zhao Xin was afraid of them, so after going there once, he didn't dare to go there again.

but……

Now is not the time to talk about this. They have finally come back, and you have to give them time to reunite with their families. So, next, these crew members went home, slaughtered chickens and ducks, and reunited with their families.

As for what you said about going out to sea next time.

I guess we’ll have to wait until next year at the earliest.

This year.

Zhao Xin also ate the pumpkin smoothly.

But, to be honest... the taste of this pumpkin is not as delicious as the varieties cultivated in later generations.

But it can also be eaten with rice.
