Holding the information handed over by Du Ruhui in his hand, Li Shimin pondered for a while and then ordered:

"Summoning Pei Shiqing."

The arrival of the envoy of the Wa Kingdom was quite a bit of a surprise to Li Shimin.

After all, in the current planning, defeating Tuyuhun to open up the Hexi Corridor and remotely controlling the strength of the Western Regions to restore the Han Dynasty is the current first-class thing to do.

The Korean Peninsula, the Wakoku archipelago, the Nankai Islands, and beyond are the treasures of heaven.

The premise of wanting to manage it is to have a mighty naval division.

But what about the current sea master of the Tang Dynasty...... With the support of Lingnan Province and Jiangnan Province in the rear, it is still quite difficult to attack Yizhou Island, and it is impossible to expect to go to sea to deter Yidi in the East China Sea.

So at present, Li Shimin has also suspended the plan.

On the one hand, it is necessary to set up an arithmetic cabinet in Chang'an to study the classics of arithmetic, and also explore the application of them to government affairs and maritime affairs.

On the other hand, it is to recall a group of generals in the naval division, mixed with young generals led by Liu Renliang to study in Chang'an for a short time, know the maritime affairs and Yidi, know the sea and learn to sail and know the wind, and after half a year of study, they will return to the Tang Haijiang to take charge of the maritime division.

In the end, it was like Hou Junji, who summoned a fleet headed by Lu Guogong, drove a new ship to test the new method, and summarized the gains and losses and finally used it by the sea master.

And the Japanese envoys, this is indeed not in Li Shimin's plan, and he is even quite surprised.

After the battle of Baijiangkou, which was said to be good, it took a few years for the Wa State to send an envoy to the Tang Dynasty?

So after a little pondering, Li Shimin sent Du Ruhui away first, and asked him to sort out the situation of this envoy in detail.

On the other hand, he summoned Pei Shiqing, the "Wa Guotong", to come over.

After all, the Tang Dynasty at this time, if you talk about the understanding of the past of the Japanese state, you should first recommend this former Sui "sent Japanese envoy".

After Wei Zheng learned about this person's past, Li Shimin promoted him from the noble and idle driver to the secretary and supervisor who was convenient for doing things.

Later, he was also personally summoned, inquired about the customs and customs of the Wa Kingdom, and ordered him to repair the book to record what he had seen and heard in the Wa Kingdom.

And now that he received the news of the envoy from the Japanese State, it was the first time after the opening of the Tang Dynasty, so after thinking about it again, Li Shimin also chose the simplest way: summoning Pei Shiqing.

Soon, the waiter who was quite fast-moving had already invited Pei Shiqing over.

Although it was the second time to see this courtier who had completed the feat of envoying to the Japanese country, Li Shimin had to sigh from his heart when he saw it with his own eyes:

It's a good material and beautiful jade.

As a messenger, the instrument must pass, and Pei Shiqing can be said to be very outstanding in this item.

Even though he is now nearly fifty years old, he still has a manly bearing standing there, and it is heartbreaking that he is not angry and arrogant.

It's just that this kind of bearing was smashed when he met Li Shimin, and I saw that he owed a debt and bowed:

"Your Majesty."

Li Shimin didn't talk nonsense, and said concisely:

"There is an envoy in the Japanese country, and now that he has arrived in Hebei Province, what does Aiqing think he should do?"

Although he has returned from the East China Sea for many years, after being re-enabled and promoted by Li Shimin, Pei Shiqing also knows quite well what he needs to do, so he said without hesitation almost immediately:

"The Japanese people are here, they must be here to ask for my Chinese culture."

"After His Majesty summoned the ministers, the ministers visited in their leisure time and learned that in the sixth year of Wude, some of the monks left behind in China with the envoys of the Japanese State in the former Sui Dynasty had left the temple and returned to their hometowns."

"At that time, it was eight years ago, and it should be these monks who returned to their hometowns and called me the prestige of the Tang Dynasty, so they wanted to do the old things of the great cause, admired my Chinese etiquette, and sent envoys to learn."

"The ministers used to walk in the country of Japanese slaves, and their people were barbaric and did not know etiquette, and their kings were vulgar and shameless, and calling themselves the Son of Heaven at sunrise was the arrogant and presumptuous words of Yelang."

"Now Your Majesty hangs the people and captures the crime in favor of His Royal Highness, and the prestige of the Tang Dynasty is spread in the south of the Mo Dynasty to Liaodong, and the Japanese people will definitely be in this trip when the two forces of war are difficult to inherit Your Majesty's heavenly might, and it is appropriate for Your Majesty to make a choice."

Listening to Pei Shiqing's eloquent and confident attitude, when he heard the words "shameless", Li Shimin looked at this handsome face for a while and was a little distracted.

After knowing Pei Shiqing's person, Li Shimin also ordered the Baiqi Division to search for the other members of the mission who went to sea with Pei Shiqing.

It's not that I don't believe this courtier, but the information pieced together by the mouths of everyone can be more comprehensive after all.

It's just that the years have passed, and the rest of the mission didn't find many at the beginning, but the people of the Hundred Horsemen brought back a small piece of news:

It is rumored that when the former Sui mission went to Dongying, because the Japanese were generally less than five feet tall, they thought that they were gods when they saw that the Han missions all had seven-foot bodies.

The queen of the Japanese people even sent her daughter to the Sui Embassy Mansion, wanting to keep her blood.

Li Shimin only thought it was absurd before, but now that he knows the behavior of this Japanese royal family, and then looks at Pei Shiqing's mighty appearance, it is not ......

"Your Majesty?"

"Ahem!"

After Pei Shiqing finished speaking, he couldn't see Li Shimin's response, so he called out, and the Tang Emperor, who was interrupted from his reverie, came back to his senses.

coughed twice to hide his embarrassment, and slowly nodded his head in approval.

The two of them stood in the manna hall like this, Li Shimin pondered and chose to ask bluntly:

"If you want to establish the country forever, how does Aiqing think it should be systematized?"

These puzzling words made Pei Shiqing a little surprised:

"Your Majesty."

After organizing the words, Pei Shiqing organized the words and said:

"The Japanese are despicable, and they have no such ability."

Of course, Pei Shiqing's opinion can't be wrong, after all, he has seen it with his own eyes, and this judgment is indeed reasonable.

It can only be said that after the tempering of what he saw and heard in later generations, Li Shimin has learned to look at problems from another angle.

It is not difficult to solve the woes alone, build the Tang Dynasty Sea Division, seal the country and cut off its sea routes, so that its people are ignorant and unaware, and then secretly support the Japanese people to hang their Japanese kings, so that the island cities and counties on this side will never be at peace, and they can be protected for hundreds of years.

But at this time, knowing the weight of the ocean, Li Shimin naturally knew the value of this series of slender islands.

If China can finally set up a naval guard in this archipelago, it will turn the East China Sea into an inland sea like the Roman Mediterranean, keeping the enemy out of the country and maintaining peace in the sea and frontier.

Not to mention that there is also a mountain of silver on Nawa Island, which can supply 30% of the world's silver, and its real estate is not as rich as the island, but considering its geographical location, it is still superior.

Although it is not clear whether Liu Renliang can lead his army to the island of Wa in the first day of Zhenzhenguan, Li Shimin feels that it is better to make plans early for such a century-old plan, such as now.

Pei Shiqing argued for a sentence, but then felt that it was not good to refute it so strongly, so he planned to make up for two sentences.

But as soon as I looked up, I saw that His Majesty had turned his back and stood with his hands in his hands.

It was also at the same time that Pei Shiqing noticed that the decorations in this manna hall were all new, especially a huge map on the right side of the hall, which instantly took away all Pei Shiqing's attention, and he noticed the word Chang'an marked on the map for the first time.

This is the map? But how can it be like this......

Pei Shiqing is not easy to describe, but the experience of sketching nautical charts when the East China Sea envoys fought the wind and waves in the past told him that the map of the Liaodong Sea is basically the same!

But if it's true, it's amazing......

At this time, Li Shimin's faint voice sounded:

"Aiqing knows that the ocean is vast and accounts for seventy percent of the world, and if you want to survive in the future, you need to defend the sea first?"

"Aiqing, do you know that we are the people who live on the earth, and there are barbarians among the stars who want to invade the earth?"

"Aiqing knows that if you want to be salty from all over the world, the only way to conquer the sea?"

The faint voice gradually became excited, and the gaze staring at Pei Shiqing gradually became hot.

Intellectually, he told this handsome old man that he should shout for the Imperial Doctor at this moment, but emotionally speaking, he felt that His Majesty's words must be targeted.

Under the difficult choice, Pei Shiqing finally said word by word:

"Your Majesty's words, there are ......"

"Sit!" Li Shimin concisely stretched out his hand to let Pei Shiqing sit down, and then recalled:

"That's a long time ago."

Just when the small class of the Ganlu Hall began, Yan Lide, who would be the supervisor, looked at the cracked pedestal in front of him with a look of regret:

"Is there really such a big difference between this volcanic ash and slag?"

The young eunuch next to Wen Yan was a little curious:

"What is volcanic ash?"

He and Yan Lide are quite familiar with each other, because at the beginning of last year, the two were both young eunuchs, but later Yan Lide was favored by Li Shimin and was promoted, and the word "less" was successfully removed.

But after being promoted, Yan Lide did not forget his original colleagues every time he had "new ideas", and the relationship became more and more harmonious.

At this moment, hearing the young eunuch's question, Colonel Zuo, Officer Zhen, Baigong and so on next to him also looked up curiously, wanting to learn more about the "cement" that was called "cement" by the prison in front of them.

"Volcanic ash is produced from volcanoes."

Yan Lide said as a matter of course, and this answer made the people who would be imprisoned more and more confused:

So what is a volcano?

Yan Lide naturally didn't know, but he chose to clap his hands and said:

"Okay, since this doesn't work, then readjust the ratio of soil, slag and lime, and try again!"

With the order, the people present also put away their curiosity and took action.

Yan Lide stood in place, picked up an iron rod and slashed along the crack of the cement base, smashed it open, and carefully observed the cracking inside it.

Just feeling the pain of being shocked by this cement in his hands, Yan Lide also initially knew why this cement was favored by later generations and called it "black technology".

I guess that's what it means to be more technological.

The young eunuch next to him also came to help, and also found an iron rod and tried to pry the cement open to facilitate Yan Lide's observation.

With a grateful smile, Yan Lide groped for the inside of the cement and fell into deep thought.

There are several things that are needed for cement formula in Chang'an, and then they will be the power of the supervisors, and soon they will try to find a good cement ratio.

But the problem of agglomeration and cracking after drying has been bothering Yan Lide immediately.

At this time, the young eunuch looked at Yan Lide's thoughtful appearance, and said casually:

"Maybe it's missing a rafter?"
