Five heads shaking fast? I held out a finger: "At least a year, they must cross the boundless desert and the Gobi, the mountains and plains where countless dangers are buried, and the regions of those barbarian peoples who are as greedy as jackals, to reach the borders of our Datang." "It is no exaggeration to say that it took less than half a year for the spies I sent to reach Constantinople, the capital of Byzantium, which we call Great Qin. But the average person travels through Eurasia for at least ** months, and the long one takes at least a year.

Hiss...... The five students all changed their faces and gasped, a year, how many years can a person's life have?

"You should also know, why is my Datang so prosperous? It is to do trade, mainly that is, international trade, and export a large number of high-end luxury goods such as silk and porcelain in exchange for all kinds of goods we need. I sat down and motioned for all the princes to come over, and knelt on the low couch obediently to listen to my explanation.

"But do you know? If our Datang ships depart from Guangzhou or Quanzhou, they will pass through the Strait of Malacca, well, that is, the small place of Luoyue. Then pass through the country of the naked man, the country of the lion along the coast of Tianzhu, you can go directly to the Bay of Waves, do you know how long this waterway is? More than 15,000 miles. But our Datang ship comes and goes, it only takes a year, you calculate, a person can only carry fifty catties of goods, but also carry the same amount of water and food, each to a supply place, but also a large amount of water and food, but a caravan of 1,000 people, can carry no more than 10,000 catties of goods, and also needs a large number of means of transportation to carry all kinds of food and medicine.

But the sea is different, my Datang's shipbuilding industry is developed, I think a few of you don't know, I'll give you an analogy, my Datang's largest ocean-going ship, can be more than 60 meters long, more than 10 meters wide, can carry tens of thousands of catties of goods, but only need more than 300 sailors, and the corresponding food, you say, which way to do business is better? ”

"It must be by sea." Li Zhi's eyes were green, and he gritted his teeth and popped out such a sentence, like a hungry dog that saw meat and bones, greed and plunder seem to be his real surname, I am very satisfied, Li Zhi, who was originally weak and has some unenterprising mentality, now has a strong aggressive ambition than before, under my bewitchment, he even surpasses Uncle Li for the land, but this point, for the time being, will only show his extremely aggressive side in front of me. Because at the moment, he is only the crown prince, a very virtuous and virtuous prince.

---------------------------------------------------- "What's more, my Datang Haiqiang is thousands of miles away, do you think there is really no danger?" Your attitude is first and foremost not to drop. "I played a long note very well. Ignoring the five pairs of white eyes, he cleared his throat and continued: "This is the difference in the angle we stand, and the eyes will also be different, what you see is only in front of you, but you don't look at the whole thing with a strategic thinking." ”

Harvesting five pairs of white eyes again, I don't care about it, mainly because I'm used to this kind of education, although they are very disdainful on the surface, but the pair of stunned ears, subconsciously clenched fists, exposed their inner thirst for salvation by the deep analysis of things, and almost wanted to pinch my neck to make me speak, but on the surface, one or two pretended not to care.

I know very well that children of this age, poor babies, and the teenagers of later generations are the same, a typical adolescent rebellious psychological syndrome, in any era, young people are a group of actions higher than thinking, blood is commonplace, you let him chase the dog, he has the ability to catch chickens for you, to deal with such children, as the educational talent filled out of the later generations of cramming education, I have always not advocated corporal punishment education, of course, occasionally slap them a few times, this is only a kind of teacher's concern and love for students.

The long teaching experience has led me to a conclusion. For adolescent rebellious children, what is most needed is not prevention and strict control, but guidance. I would never use a whip to teach a stubborn donkey a temper in which direction to go, but I would only walk slowly and leisurely, dropping a sweet date or half a carrot from time to time. The same is true for these children, and the results can be achieved as well.

"You should know that since the Han Dynasty, my Tang Dynasty's Haiqiang has often suffered from border troubles, I don't know if you have heard of it?" I narrowed my eyes and glanced at them.

Li Shen was the first to open his mouth: "I know, from the Han Dynasty to the present, the troubles of the sea frontier have not subsided, from the north to the south, there are sea troubles, carefully remember the Han Dynasty, there were two records about the Japanese people scratching my coast, whether it was the Northern and Southern Dynasties or the previous dynasty, there were also such records, but now my Tang Dynasty is prosperous, and the Japanese people naturally dare not worship it." ”

"Well, that's right, but since you know about this, let me ask you, why did the Japanese come to rob the people of my land in China?" I took a sip of my tea and continued to guide. "It's nothing more than a sharp word." Li Zhi replied very simply, yes, keeping my education in mind.

"That's right, then I want to ask you, what is good in your eyes?"

"Leigh? It was nothing more than gold, silver, copper, iron, silk, cloth, and grain. "Li Fu on the side gave me a pitiful, extremely narrow explanation. On the side, Li Zhi blinked: "There are also land, mineral deposits and all living resources." ”

"Well, Koji answered well. But do you know that my Tang Dynasty is going down from the flow ball, and there is a big island called Luzon, do you know what is on it? And what is on the top of that Wa Kingdom that buzzed like a fly in front of our Datang all day? ”

A bunch of boys were all stupid, moving their heads sideways.

"Be careful, go get the map." I waved my hand at Li Shen, and the little guy ran as fast as he could, and after a short time in the apse, he walked back with a map in his hand.

"This is the big island called Luzon that I just said, there are no people, but it has the high-quality iron and copper ore that my Datang needs most, and they can be used by my Datang for more than a thousand years......" I said softly, and the five little children all gasped viciously, and their eyes almost turned into a raised tangram tower.

---------------------------------------------------- copper, Datang is currently lacking in this thing, mainly because its function occupies almost all industries in Datang, the production of artillery needs it, and the production of various utensils is also inseparable from it, in addition, due to the economic strength of Datang, Datang's copper coins have become the common currency of Datang and its surrounding subject countries, even if Datang mints three million new currencies every year, It is still in short supply, but this is already the current limit of Datang, because of the current technical content limitations, coupled with the excellent surname of copper products in rust prevention, so that the scope of copper products is much larger than that of iron products, it is such a reason that Datang every year to find new copper ore veins and rack their brains, China is too big, but because it is too big, it makes the mineral source more difficult to find, and the opening of copper mines in the past is almost in short supply.

"Hundreds of years?" Li Zhi dropped a drop of saliva on the map, quickly wiped it off with his sleeve, and saw that his four younger brothers were currently in a posture of dilated pupils, and no one noticed his embarrassment, he couldn't help but breathe a sigh of relief, and squeezed his eyes at me obscenely: "Brother Jun, you shouldn't be lying to us, right?" For more than a thousand years, how much copper does that have? Isn't that island all made of brass? Li Zhi's dirty expression really made me feel the urge to kick his face, and I took a few deep breaths, and the noble feelings of the teacher made me regain the momentum of being a teacher.

"Lie to you?" I gave this little kid a dart, but my son has taught world geography, and he has to eat everything he teaches, otherwise, where does my reputation as a general teacher come from? Not to mention the Philippines, the minerals of the Japanese people are even clearer to me.

"What good can I do by lying to you? Could it be that if I deceive you, I will be able to have a good meal and drink? Let me tell you, this son is absolutely not exaggerating, my Datang is now only producing more than 200,000 catties of copper every year, do you know that there are nearly ...... on Luzon Island Wait, wait for the teacher to convert, for the teacher to remember that it seems to be nearly four billion tons, and when it is converted, I am afraid that according to our current mining method, there will be no problem for one or two thousand years. This is still for the teacher, and iron, I'm afraid there must be half of the amount of copper...... "I smash my mouth, it's a magic stick's calculation, I don't know if there are so many, but what I know is that according to the current mining level of Datang, it is definitely possible to mine the copper and iron ore in Luzon, where the purity of the ore quality is very good, the most important thing is that compared to the vast Datang Dynasty, it is very concentrated, and the fart is a big place, and the veins are not easy to find?" Datang alone has hundreds of experienced prospectors.

I also know that Luzon still has countless reserves of more than 100 million tons of gold and billions of barrels of oil, which, let's not mention, is for another place. Besides, now that oil has a fart purpose, it's on the bottom of the sea, not on land.
