Datang: Li Shimin begged me to rebel

According to the investigation of later generations, the entire Lancang River is a rare river that can be fully navigable after a slight rectification!This means that if the ship is powerful enough, the amount of land it can control along the river is too large!And the ships are enough to load soldiers, heavy bed crossbows, supply weapons, etc., and even the marching speed in Southeast Asia is much faster than land marching, because if this thing has a moon, when the weather is clear, the ship can be sailed at night and during the day.

"Nanzhao and other places are more difficult to march from land, but in fact, if you start from Guangzhou, then march here by boat, then arrive at the Lancang River, and then go upstream, it is not too difficult. This way, we can besiege Nanzhao from multiple angles. If it is, it is not difficult to take down the opponent." Li Ke said calmly.

To put it bluntly, if Datang controlled Vietnam, Laos, Thailand and other places in later generations through Lingnan Road, and in turn surrounded Yunnan and Guizhou in the hinterland, then it would not be difficult to solve them at all. , Don't you want to clean up how to clean up?

"As for these places, they are currently the source of the Kunlun slaves of the Tang Dynasty." Li Ke pointed to Malay, Indonesia, the Philippines and other places in later generations. "The land area of ​​these places is not small, and the climate It is also suitable for growing crops. Because they are hot all year round."

"The black people in these places, that is, the Kunlun slaves are still in the uncivilized stage. They don't have any concept of land at all. It is not difficult for us to build a town and port on it."

"In this way, the ships of Datang along the way will have a place for supplies in the future."

"And the ocean can also bring huge profits. As long as we control the production of advanced sea-going ships, then this means that we control the ocean."

"The simplest point, father, brother, if we can build a sea ship worth 1 hu, one ship can carry thousands of soldiers, and ten ships are enough to carry an army of [-] people. If we are willing, We can all attack Persia from the sea and conquer the land, and we will gradually expand our victories. If we are unable to fight, we can retreat by boat at any time, and the enemy will not be able to catch up."

"In this way, we will remain invincible." Li Ke told Li Shimin about the importance of sea power.

Seeing Li Ke constantly scratching on the map, Li Shimin and Li Chengqian were in a trance, as if this was not a map, but the land of the Tang Dynasty.

"Until one day, my national flag of Tang Dynasty can be planted in all corners of these places!" Li Ke simply drew a circle on the entire map with a wooden stick.

Li Shimin couldn't hold back anymore, good guy, your cake is too big for your father.

"You..." Li Shimin said: "The premise is that there must be enough sea ships, and they must be advanced enough. What you mean is that the sea ships you researched are very advanced?"

"Yes, at least it is more advanced than Datang's sea-going ships. A sea-going ship of [-] hu is unlikely, but there is no problem with a sea-going ship of [-] or even [-] hu. Moreover, if the iron-making craftsmen developed by Erchen craftsmen Steelmaking technology is constantly improving, father, steel can also be used for shipbuilding!" Li Ke said.

Li Shimin and Li Chengqian looked at each other, and they were not very shocked. In fact, many people thought that the ancients would be shocked to hear that steel can build ships, but they were not.

Because the ancients didn’t use steel to build ships because they couldn’t afford them. They had basic theories and cognitions about buoyancy and so on. The simplest point is that the ancient royal families and nobles had iron pots and basins, at least in the Tang Dynasty. There is.

An iron basin can float when thrown into the water, why not an iron boat?So the ancients of steel shipbuilding were not so shocked, but firstly they couldn’t afford it, secondly they had no technology, and thirdly they were unnecessary. Wooden boats were enough, so why do we need iron boats?

"Iron ships made of steel are stronger, and they are not afraid of fire and the like. And they can be made even bigger! At that time, it is not certain that a ship can transport tens of thousands of soldiers. The premise of these is to ensure that Shipbuilding technology must be kept in absolute secrecy."

"Actually, Dad, this is one of the reasons why I insist on giving titles to these craftsmen." Li Ke said with a smile.

Li Shimin and Li Chengqian looked at each other. If they hadn't figured it out before, these things were enough for them to figure it out and realize the importance of craftsmen.

"When will the nationwide universal school you mentioned be achieved?" Li Shimin asked suddenly.

"Actually, it can be done at any time, but the current conditions are not met, so I want to wait for a while, at least until the spring plowing is over." Li Ke thought for a while and said.

"Okay! Execute as soon as possible. How much pressure is there this time? Dad will bear it for you. Since these craftsmen are important, then the promise to them must be fulfilled, so that their children can go to school, and people who have learned knowledge will be trained to become It's obviously easier for a craftsman." Li Shimin nodded directly.

"No problem. By the way, I forgot what I just said, Dad, you have to give me the authorization to use the eight hundred li express, I have to hire someone back to Chang'an, and let him build the sea ship first Get up." Li Ke thought for a while and said.

"Yes." Li Shimin nodded directly. The [-]-mile express service is not just for casual use, it must be authorized by him.

"That's okay. Just two days later, my Datang Everbright City will start auctioning land. At that time, let these merchants start paying for it. This time, the caravan will be called Datang Royal Shipping Group." Li Ke smiled and said, "We are going to do business this time. Of course we don't need to go through the court."

Li Shimin: "..."

"Look at it." Li Shimin was a little helpless. What Li Ke said was not unreasonable. If it passed through the court, this matter might be leaked. Instead, it seems better to use normal business practices to conceal it?

"Did you two hear that?" Li Shimin looked at Chang Lin and Qi Julang and asked.

"Yes!" Chang Lin and Qi Julang both hurriedly saluted.

"If the sixth person knows the real purpose of this matter, and the three of us didn't say it, then you two, Zhu Jiuzu, I won't investigate who said it." Li Shimin's tone was very flat, but often Both Lin and Qijulang knew that Li Shimin was not joking.

"Yes!" Both Chang Lin and Qi Lang bowed down to salute.

"Chang's servant, prepare to draw up an edict, and hurry up in eight hundred miles." Li Ke turned around and walked to the table next to him, and then picked up the brush and special paper on the table.

And Chang Lin quickly prepared sealing wax and other items from the side.
