Spoiling History: Starting from the Three Kingdoms

Holding the information handed over by Du Ruhui in his hand, Li Shimin thought about it for a moment and then ordered:

Summon Pei Shiqing.

The arrival of the Japanese envoy was a bit unexpected for Li Shimin.

After all, in the current planning, defeating Tuyuhun to open up the Hexi Corridor and remotely managing the Western Regions to restore the prosperity of the Han Dynasty are the top priorities.

The Korean Peninsula, the Japanese Islands, the South China Sea Islands, and the islands further away can be called heaven-sent treasure houses.

The prerequisite for managing it is to have a mighty naval force.

But the current navy of the Tang Dynasty... with the support of Lingnan Dao and Jiangnan Dao, it is still quite difficult to conquer Yizhou Island, and they cannot hope to go to sea to frighten the Yi Di in the East China Sea.

Therefore, Li Shimin has also postponed his plans for now.

On the one hand, a pavilion of arithmetic should be established in Chang'an. In addition to studying the classics of arithmetic, we should also explore its application in government affairs and maritime affairs.

On the other hand, they recalled a group of naval generals and mixed them with young generals headed by Liu Rengui to study together in Chang'an for a short period of time. They learned about the sea and the barbarians, learned about the sea conditions, learned sailing skills, and learned about the wind. After half a year of studying, they would return to China. The maritime territories of the Tang Dynasty were jointly in charge of the navy.

In the end, Ruhou Jun gathered, led by Lu Guogong, summoned a fleet, sailed new ships, tried new methods, summed up the gains and losses, and finally used them for the navy.

As for the Japanese envoys, this was indeed not part of Li Shimin's plan, and he was even quite surprised.

After the agreed-upon Battle of Baijiangkou, it took several more years before the Japanese government sent an envoy to the Tang Dynasty?

So after thinking about it for a while, Li Shimin sent Du Ruhui away first and asked him to sort out the situation of this Japanese envoy in detail.

On the other hand, Pei Shiqing, the Japanese master, was summoned.

After all, in the Tang Dynasty at this time, when it comes to understanding the past of the Japanese country, the first envoy to the Japanese of the former Sui Dynasty should be recommended.

After Wei Zheng learned about this person's past, Li Shimin promoted him from a noble and leisurely doctor in the driving department to a secretary supervisor who was convenient for work.

Later, he personally summoned him, asked about the customs and customs of the Japanese country, and ordered him to write a book to record what he had seen and heard about the Japanese country.

Now, it was the first time since the founding of the Tang Dynasty that he received news of an envoy from Japan. So after careful consideration, Li Shimin chose the simplest way: summon Pei Shiqing.

And soon, the quick-moving chamberlain invited Pei Shiqing over.

Although this was the second time he saw this minister who had accomplished the feat of being an envoy to Japan, Li Shimin had to sigh from the bottom of his heart when he saw it with his own eyes:

Rather, he is a talented person.

As an envoy, his appearance must be up to standard, and Pei Shiqing can be said to be very outstanding in this aspect.

Even though he is nearly fifty now, he still has a manly demeanor when he stands there, and he is not angry and proud, which is heart-breaking.

However, this magnanimity was shattered when he met Li Shimin. He bowed and saluted:

His Majesty.

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

The Japanese envoy has arrived at Hebei Province. What do you think we should do?

Although he had returned from the East China Sea for many years, after being re-elected and promoted by Li Shimin, Pei Shiqing also knew exactly what he needed to do, so he said without hesitation almost immediately:

The Japanese people must have come here to seek our Chinese culture.

After His Majesty summoned the ministers, I visited in my spare time and learned that in the sixth year of Taketoku, some of the monks who had accompanied the Japanese envoys to China during the Sui Dynasty had bid farewell to the temple and returned home.

It was eight years ago now. These Japanese monks must have returned home to praise our reputation in the Tang Dynasty. Therefore, they wanted to carry out great achievements in the past. They admired my Chinese etiquette and sent envoys to learn from it.

In the past, I traveled to the Japanese slave country. Its people were barbaric and ignorant of etiquette, and its king was vulgar and ignorant of shame. He called himself the Emperor of the Place Where the Sun Rises, but he was arrogant and arrogant.

Now that your Majesty is vindicating the people to conquer crimes and capture Jie to benefit His Highness, and to promote the power of the Tang Dynasty in Monan and spread it to Liaodong, the Japanese will certainly be unable to inherit His Majesty's power in a war between two groups. It is appropriate for Your Majesty to make a decision.

Listening to Pei Shiqing's talk about his confident attitude, when he heard the words shameless, Li Shimin was a little distracted for a while looking at this handsome face.

After learning about Pei Shiqing, Li Shimin also ordered Baiqisi to search for other members of the mission who had gone to sea with Pei Shiqing.

It's not that I don't believe this minister, but the information pieced together from everyone's mouth can finally be more comprehensive.

It's just that it's been a long time, and the other members of the mission didn't find many of them at the time. On the contrary, the people from Baiqisi brought back a piece of gossip:

It is said that when the former Sui Dynasty envoys arrived in Japan, because the Japanese were generally less than five feet tall, they saw that the Han envoys all had seven-foot tall bodies and thought they were gods.

The Japanese queen even sent her biological daughter to the Sui embassy to preserve her bloodline.

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

His Majesty?

Ahem!

After Pei Shiqing didn't see Li Shimin's response, he called out. The Emperor of the Tang Dynasty, who had been interrupted from his reverie, came back to his senses.

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

The two of them just stood in the Manna Hall. Li Shimin pondered for a while and then asked directly:

If you want to permanently control the Japanese kingdom, how do you think we should control it?

Pei Shiqing was a little surprised by these confusing words:

His Majesty.

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

Japanese people are despicable, and they are definitely incapable of doing this.

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

It can only be said that Li Shimin has learned to look at problems from another angle after being tempered by his later experiences.

It is not difficult to simply eliminate the Japanese troubles. We built the Tang Dynasty Navy, sealed off the country's gates and cut off its sea routes, so that the people were ignorant and unaware, and then secretly supported the Japanese to attack their Japanese kings, so that the islands, cities and counties in this area would fight against each other and never have peace. , it can be protected for hundreds of years.

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

If China can finally establish a naval garrison on this archipelago, it can turn the East China Sea into an inland sea like the Roman Mediterranean, keeping enemies out of the country and maintaining tranquility on the sea frontier.

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

Although it was unclear whether Liu Rengui could lead his troops to the Japanese island in the Zhongzhenguan Dynasty, Li Shimin felt that it was better to make plans for such a century-old plan in advance, like now.

Pei Shiqing argued hard, but then he felt that such a strong rebuttal was not good, so he planned to add a few words.

But when I looked up, I saw that His Majesty had turned his back and was standing with his hands behind his back.

It was also at the same time that Pei Shiqing noticed that the decorations in the Manna Hall were all new and strange, especially a giant map on the right side of the hall. In an instant, Pei Shiqing took away all of his attention, and he immediately noticed what was on the map. Marked with the word Chang'an.

Is this a map? But how could it be like this...

Pei Shiqing couldn't describe it, but his experience in drafting sea maps when he was on a mission to the East China Sea to fight against the storms told him that the map of the Liaodong sea area was roughly the same!

But if it is true, it is really amazing...

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

My dear, do you know that the ocean is vast and occupies 70% of the world here. If you want to survive in the future, you must first defend the ocean?

My dear, 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?

My dear, do you know that if you want to conquer the world, you can only defend the sea?

Youyou's voice gradually became passionate, and the eyes staring at Pei Shiqing gradually became hot.

Rationally, he told this handsome old man that he should call for the imperial doctor at this moment, but emotionally, he felt that His Majesty's words must be targeted.

After making a difficult decision, Pei Shiqing finally said word by word:

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

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

To put it into perspective, it was quite a long time ago.

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

Is the difference between volcanic ash and slag really that big?

Hearing this, the young prisoner next to him was a little curious:

What is volcanic ash?

He and Yan Lide were relatively familiar with each other, because they were both serving as young prisoners at the beginning of last year. However, Yan Lide later gained Li Shimin's favor and was promoted, and successfully removed the word younger.

However, after being promoted, Yan Lide never forgot his former colleagues every time he had new ideas, and the relationship became more harmonious. At this moment, he became curious when he listened to Yan Lide talking to himself.

At this moment, hearing the young supervisor's question, Zuo Xiao, Zhen Guan, Baigong, etc. beside them also raised their heads curiously, wanting to learn more about the cement that the supervisor in front of them called cement.

Volcanic ash is naturally produced from volcanoes.

Yan Lide said matter-of-factly, and this answer made everyone who would be the prisoner more and more confused:

What is a volcano?

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

Okay, since that doesn't work, let's reconstitute the ratio of soil, slag and lime and try again!

Following the order, everyone present put away their curiosity and took action.

Yan Lide stood there, picked up the iron rod and slashed along the cracks in the cement base, smashing it open and carefully observing the cracks inside.

Just feeling the pain on his hands from the shock of the cement, Yan Lide also initially understood why this cement was favored by later generations and called it black technology.

I guess this is what better technology means.

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

Smiling gratefully, Yan Lide groped the inside of the cement and fell into deep thought.

Several things needed for the cement formula were available in Chang'an. Together with the efforts of the general supervisor, we soon tried to come up with a pretty good cement ratio.

However, the problem of agglomeration and cracking after drying has always troubled Yan Lide.

At this time, the young eunuch looked at Yan Lide thinking hard and said casually:

Perhaps this thing is missing a rafter beam?
