In fact, Zhang Feng really didn't expect that Yu Shinan's people would have such a great resistance to this matter.

However, when Yu Shinan was just talking, he also thought of one thing, that is, the struggle between Wen Chen and Wu Jiang during the Zhenguan period. He immediately knew something. Many people said that Li Shimin, the current emperor, valued martial arts and despised literature. Even some people angrily scolded Li Shimin. He was careless and only knew the regime on horseback, But where would they know if it was militaristic.

This will really make a country perish and can't last long.

If, as in the Song Dynasty, the emphasis is on literature and the light is on martial arts, then it will make a country.

Become like rotten catkins in general, have a superficial appearance, rotten catkins in it.

What's the use?

In their own academy, Yu Shinan and others seem to have only thought of one aspect, but they seem to have automatically filtered out the aspects of military science and medicine.

If there were no such people and soldiers to guard the border, if nothing else, it would be the collapse of the Tang Dynasty.

In addition to the current situation, at this time, they only know to recite poems against each other all day and talk about ancient and modern times. But have they ever thought about the border dispute? Is it really that they can solve it with only one mouth? If so, the world will be really peaceful.

I can only think about it.

Blacksmithing also needs its own hard work, not to mention a country. If there is no powerful military to be deterred, where will the world be peaceful and where will these literati talk about the past and the present under the bright mirror.

Zhang Feng, it's very clear that if you want to change this era at this time, everyone's pedantic psychology is very difficult, very difficult.

But he never thought it would be so difficult. At first, he thought that Yu Shinan and others were the only people.

These things he showed, these four people can rise, should have, which means that they have accepted this kind of people, but at this time, due to the emergence of a forging workshop, the four people are so angry. Obviously, they think too much. In their bones, they are still pedantic.

"Several teachers let the students give you a detailed explanation. Why are the students so?"

See a few people, don't talk, just smoke one by one. It seems that the cigarette made by Zhengfeng at this time has infinite magic.

Zhang Feng couldn't help feeling a little sick.

Sir, didn't you say that I can't make things? Then why can you accept this cigarette? But I just set up a forging house. Is that what you do?

Seeing this, Zhang Feng said, "several teachers think that the boy made this cigarette. How does it taste and how does it work?"

Several people didn't know what Zhang Feng wanted to express, but they still nodded and answered Zhang Feng.

Zhang Feng said, in fact, several teachers don't know. The smoking raw materials in your hands are from the hands of businessmen in the returning country. Not only is it, but also this raw material. For example, there is a kind of thing that people can grow wildly in the dry land, especially one that can grow in the field without rain in a year. This kind of thing is called potato and another is called sweet potato, If these two things are introduced into Datang, there will never be a food shortage crisis in Datang, and these things are tens of thousands of miles away. "

Yu Shinan and others heard the speech and couldn't help jumping their eyelids. Looking at the smoke in their hands, it's hard to smoke at this time. They can't help it if they don't want to smoke.

Sun Simiao seemed more interested in this. He couldn't help asking, "boy, you're serious. There is really that kind of food. If so, isn't this country very rich?"

Zhang Feng nodded, then picked up the rag on the table, wiped all the things written by the people who had previously handed over to Li Chengqian on the self-made blackboard, then twisted a self-made chalk and drew a big circle on it.

"This is where we live. We are in this circle, and the location of our lobby is probably in this place."

While talking, Zhang Feng drew a circle in one place, wrote the word Datang in the circle, and then said: "In fact, you should also know that there is an endless sea in the east of Datang, but do you know that at the end of the sea, there is a wild land. On this land, there are many things we don't know and don't know. In fact, some wild people are prepared to use them as the most basic rations, and even a large part of them are in the waves Fee, there are what the boy just said, potatoes and sweet potatoes, and even some things you haven't heard of. "

"Such as pepper and corn."

"These things are far away, but if we want to rely on these things, transportation, for example, we are going to God or Persia.

It takes at least half a year to go back and forth, and many of these things are uncertain.

We want to explore the outside world, and the outside world also wants to explore our Datang. For example, a big food country in black just appeared before is very prosperous. As far as I know, the national strength of this country is no less than Datang! "
