Five heads shaking fast? I stretched out a finger: "At least one year, they must travel through the boundless deserts and Gobi, and there are no burials of dangerous mountains and plains, and those greedy barbarian nations like jackals to reach the border of our Tang Dynasty." There is no exaggeration. The spies I sent only took less than half a year to reach Constantinople, the capital of the Qin Dynasty, the Byzantium, which we call the Great Qin Dynasty. But it takes at least eight or nine months for ordinary people to travel through the Eurasian continent, and at least one year for a long time.

Hiss... The five students all changed their faces and took a breath. How many years can a person's life be in a year?

"You should also know why my Tang Dynasty was so prosperous? It relied on trade, mainly international trade, and a large number of high-end luxury goods such as silk and porcelain were exported to exchange for all the items we needed." I sat down and signaled that the princes would all gather around, kneel obediently on the couch, and listen to my explanation.

"But do you know? If our Tang Dynasty ships set out from Guangzhou or Quanzhou and go to the Strait of Malacca, well, that is, the small place of Luoyue. Then pass through the Naked Man Kingdom and the Lion Kingdom along the coast of India, you can directly reach Boqi Bay. Do you know how long this waterway is? More than 15,000 miles. But our Tang Dynasty ships only take a year to go back and forth. You can calculate that one person can only carry fifty kilograms of cargo, and carry the same amount of water and food. Every time he arrives at a supply land, he has to replenish water and food. However, a caravan with a thousand people can carry only ten thousand kilograms of cargo, and also require a large number of transportation to carry various food and medicines.

But the sea is different. I believe you don’t know how developed the shipbuilding industry in the Tang Dynasty is. I will give you an example. My largest ocean-going ship in the Tang Dynasty is more than 60 meters long and more than ten meters wide. It can carry tens of thousands of kilograms of cargo, but only more than 300 sailors are needed to share the corresponding food. Let me tell you which way to do business is more reasonable?”

"It must be a journey." Li Zhi's eyes were green, and he said something like a hungry dog ​​who saw flesh and bones. Greed and plunder seemed to be his nature. I am very satisfied. Li Zhi, who was originally weak and had a little unimprovemental mentality, now has a strong ambition to invade than before. Under my instigation, his desire for land even exceeded that of Uncle Li, but this will only reveal his extremely aggressive side in front of me for the time being. Because at present, he is still the crown prince, a very virtuous and virtuous prince.

"What's more, my Tang Dynasty Sea is thousands of miles away. Do you think there is really no danger? Your attitude is first of all." I said, "I rolled a long voice regardless of the five-tongue and cleared my throat and continued: "This is the difference in the angles we stand on, and the eyes will also be different. You see that the ground is just in front of you, but you don't look at the whole thing with strategic thinking."

I got five pairs of rolling my eyes again. I didn't care about this, mainly because I was used to this way of education. Although they looked very disdainful on the surface, the pair of ears that were stunned and the fists that were subconsciously tightened, exposed their hearts being saved by the deep analysis of things. They almost wanted to pinch my neck and let me speak, but on the surface, they pretended not to care.

I know very well that children at this age, poor children, look the same as the teenagers in later generations, and are typically adolescent rebellious psychological syndrome. In any era, young people are a group with actions higher than thinking. It is common for them to fill their foreheads with passion. If you ask them to chase dogs, they have the ability to catch chickens for you. For such children, as a kind of educational talent for later generations, I am used to not promoting corporal punishment education. Of course, occasionally slapping them a few times is just a kind of care and love for students by teachers. Boiling - Teng - Text - Learn to beat members by hand

Long-term teaching experience led me to a conclusion. What children with rebellious psychology most need for most is not prevention and strict control, but guidance. I will never use a whip to teach a stubborn donkey who is angry in which direction to move forward. I will only take a slow step in front of me, throwing a sweet date or half a carrot from time to time. For these children, this teaching method can also achieve good results.

"You should know that since the Han Dynasty, the strong sea in the Tang Dynasty has often suffered from border troubles. I wonder if you have heard of it?" I narrowed my eyes and glanced at them.

Li Shen opened his mouth first: "I know that until now, the troubles of the sea border have never subsided. From north to south, there are sea disasters. Shen remembers that during the Han Dynasty, there were two records about the Japanese scrambling our coast. Whether it was during the Southern and Northern Dynasties or the previous dynasties, there were also such records. However, now our Tang Dynasty is so prosperous, so naturally the Japanese dare not worship it."

"Well, it's right, but since you know this, I'll ask you, why do the Japanese come to steal the people of China?" I took a sip of tea and continued to guide. "It's nothing more than a word of profit." Li Zhi answered very simply, well, remembering my education in mind.

"Correct, then I want to ask you again, what is profit in your eyes?"

"The profit is nothing more than gold, silver, copper and iron, silk, satin and cloth, and food." Li Fu on the side gave me a pitiful, extremely narrow explanation. On the side, Li Zhi blinked: "There are also land, minerals and all survival resources."

"Well, Xiaozhi's answer is good. But do you know that my Tang Dynasty is coming down from the ball, and there is a large island called Luzon. Do you know what is there? And what is there on the Japanese country that buzzes like a fly in front of our Tang Dynasty all day long?"

The young men were all stunned and moved their heads horizontally.

"Xiao Shen, go and get the map." I waved at Li Shen. The little guy ran quickly. After a while, he quickly walked back with a map.

"This is the island I said just now called Luzon. It is not crowded, but it has the extremely high-quality iron and copper mines that my Tang Dynasty needs most. They can be digging for more than a thousand years..." With a gentle sentence, the five little kids all took a fierce breath, and their eyes almost glared into the bulging Qiqiao Linglong Tower.

Copper, what the Tang Dynasty lacks at present is this thing, mainly because its function occupies almost all industries in the Tang Dynasty. The production of artillery requires it, and the production of various vessels is also inseparable from it. In addition, due to the economic strength of the Tang Dynasty, the copper coins of the Tang Dynasty became the common currency of the Tang Dynasty and its surrounding vassal states. Even if the Tang Dynasty newly minted three million coins every year, there is still a shortage of supply, but this is the current limit of the Tang Dynasty. Because of the current technical content and the excellentness of copper products in rust prevention, it makes the boiling... 投... 投... … Learning members' hand-made copper products are much larger than iron products. It is precisely for this reason that the Tang Dynasty racked its brains to find new copper mines every year. China is really too big, but it is because it is too big that mineral sources are more difficult to find. The opening of copper mines in the past is almost in short supply.

"Hundreds of years?" Li Zhi dripped a drop of water on the map, and quickly wiped it off with his sleeves. Seeing that his four younger brothers were currently in a scattered pupils, no one noticed his embarrassment. He couldn't help but breathe a sigh of relief and squeezed at me in a despicable way: "Brother Jun, aren't you lying to us? For more than a thousand years, how much copper is that? Isn't that island made of copper?" Li Zhi's dirty expression really made me feel the urge to put his face with big feet. He took a few deep breaths. The teacher's noble sentiment restored my aura of being a role model.

"Lie you?" I slapped this little kid and glanced at the dart. I have taught world geography. I have to understand everything I teach. Otherwise, where did my reputation as a general teacher come from? Not to mention the Philippines, I can even understand the minerals in the Japanese country.

"What benefits can I have if I cheated you? Could it be that if I cheated you, I can have a good meal? Let me tell you, I have absolutely no exaggeration. The annual copper production of my Tang Dynasty is only more than 200,000 kilograms. Do you know that there is a near Luzon Island... Wait, wait, when I convert it to my teacher, I remember that it seems to be nearly 4 billion tons. If I fold it, I am afraid that according to our current method of purchasing, it will be fine for one or two thousand years. This is still a matter of being counted by the teacher.

If there is iron, I am afraid there must be half of the copper..." I smashed my mouth, and it was a charlatan to calculate. I don't know if there are so many, but what I know is that according to the current mining level of the Tang Dynasty, the copper and iron ore in Luzon can definitely be mined. The ore quality is very good. The most important thing is that it is relatively large in comparison with the vast Tang Dynasty. It is very concentrated. It is a bit too big, and it is not easy to find ore veins? There are hundreds of experienced prospecting craftsmen in the Ministry of Industry alone.
