In the classroom, a group of students sighed or gritted their teeth, and some even crushed the charcoal in their hands!

But until Mr. announced that the time had run out, they still couldn't figure out when the damn Xiao Gang would catch up with Xiao Ming! Or maybe his court judges, when will he be able to kill those thieves!

In the end, the poor baby could only take the black straw paper, cry and mourn, and go to the thirteenth to get her own piece of fried pork with bamboo shoots......

And the thirteenth who waved the whip and cleaned up these stupid students fiercely couldn't see how much hatred was on his face.

Hey, there is still a long way to go!

China Shenzhou, the land of civilization.

Since ancient times, there has been an endless stream of talented people! There are many people with great wisdom like the stars in the sky!

However, why was it left behind by the West in later generations?

Xiao Han had thought about this question before.

The difference is that what he thought before was limited by his vision and knowledge, and he was somewhat complaining.

At that time, he was no different from a fool at the head of a village, or blamed the heavens for being wrong, or blamed the ruler for being incompetent, or even blamed Confucianism for being pedantic!

However, as he came to live in Datang for a long time, Xiao Han suddenly discovered that those so-called reasons were just ridiculous excuses!

The most fundamental reason is that we only have technology, not science! In other words, what we lack is continuous research into one thing!

Since ancient times, we have given birth to many skilled craftsmen and invented many important things that can change the world!

However, we have not had a systematic research process.

A lot of things have been made, they have been effective, and they can even be exchanged for money, so that's it!

As for how it works? We don't know!

Are there any areas where they can continue to improve? Or maybe it can be used in other fields, I don't know!

"What we used to do can only be called a technique, not a technique! Technique is a kind of systematic research, which needs to be born by professional people, with professional equipment, from professional places! In this way, the development of the craft will lead to the production of new things that you see. ”

In the courtyard on the side of the Xiao family, Xiao Han leaned against a persimmon tree that had lost its leaves, and in front of him with a low voice, Chai Shao and Cheng Yanjin, who were staring at each other, explained the origin of science.

However, his painstaking efforts, against the two rough embryos in front of him, it was obvious that he had beaten the meat buns and fed them to the dogs......

"You don't have to tell me that! I'm a rough person, I don't understand! Tell me how much you can buy this thing! Or, you can exchange things for something! Cheng Yanjin glared at Chai Shao viciously, and swung a fan-sized slap hard, interrupting Xiao Han's words.

Seeing this, Chai Shao also spoke out with hatred: "That's it, you just say the price!" No matter how much money Cheng Lao Pifu drives, my old chai is definitely higher than him! ”

"You ......"

Xiao Han, who was still working tirelessly just now and teaching the world, was choked half to death by these two rough embryos, and wanted to pick up a hand from the ground and send them back to the West directly!

Okay, I just tried my best to talk for a long time, and I listened to the donkey's ears?

"Not for sale!" Xiao Han said fiercely.

"Huh?" When the two of them, who were still fighting cocks just now, heard this, they turned their heads together, and their four big eyes were staring at Xiao Han.

was stared at so fiercely by the two battlefield generals, Xiao Han was a little unbearable, and his tone couldn't help but soften: "Ahem...... It's not that they don't sell, it's that these things are too expensive, and they're all in the experimental stage, so if you get them, the benefits will be disproportionate to the pay......"

Hearing Xiao Han say this, Cheng Yanjin automatically omitted the second half of his sentence, just snorted twice, and said disdainfully: "Too expensive? How expensive can it be! I still have some money in Lao Cheng's army! ”

Chai Shao, as the general manager of the march, was even more unwilling to lag behind in this matter, and also said: "Hehe, what we are in charge of is the military camp and military quartermasters!" It's not a big deal to buy some new weapons, you just have to quote the price, if it's appropriate, how about 10,000 pieces?! ”

Xiao Han stood up straight, blinked and asked, "Rich?" ”

The two of them, who were almost fighting just now, stopped fighting each other, and looked at Xiao Han and replied in unison: "Yes!" ”

"That's good...... Let's do it! Xiao Han hesitated for a moment, and suddenly smiled maliciously.

Seeing this smile, Chai Shao and Cheng Biting Jin shuddered in their hearts for some reason.

Is it really expensive?

Xiao Han didn't pay attention to the two people whose faces changed slightly, he slowly moved to the middle of the courtyard, kicked a black pipe where it was placed, and said slowly: "This, the price is a thousand yuan!" Bullets, powder are counted separately! In addition, this one can't be used all the time, it can only be used ten times, and it must be replaced, otherwise there is a possibility of injuring your own people! ”

"What???"

Before Xiao Han's words fell, two exclamations exploded in Xiao Han's ears together! It shook his brain!

"You two are crazy? Can't you be quiet?! Xiao Han covered his ears and looked at Cheng Yanjin and Chai Shao angrily, but saw that these two were now like two toads, stammering, and their eyes were about to burst out!

"You say, it, how much does it cost?"

After a long time, Lao Cheng swallowed his saliva with difficulty, and asked again in disbelief.

In other words, he just wanted to learn Xiao Han to kick and kick the pipe, but now when he heard the price, this foot didn't dare to lean on that side even if he was killed, for fear that if he touched it, he would be relied on by Xiao Han and asked him to buy it!

When Xiao Han saw the appearance of the two of them, he was not angry, but proudly hugged his arms and said, "One thousand runs!" Hey, don't be too expensive, it's still up to us to have a good relationship, and I'll give you a 50% discount! ”

"A thousand? Also 5% off? ”

At this time, before Cheng Yanjin could speak, Chai Shao had already jumped up, pointed to the black broken pipe and scolded: "Why don't you break my bones?" A thousand times, even if this thing is made of gold, it's not worth the price, right? Are the two of us wronged? ”

"Huh? How can you be wronged? Although you both do have big heads......"

Xiao Han rolled up his sleeves to block the foaming stars that spewed out of Chai Shao's mouth, and laughed wickedly.

"You!" The two of them were not popular, so they rolled up their sleeves together and were ready to pounce!

Seeing this, Xiao Han was intimidated again......

He hurriedly waved his hand: "Hey, don't be angry! Do business, make money in harmony! Why don't you hear me about how this thing came to be, and then see if it's the right price? ”

"I don't care how it came to be......"

"Zhijie, if you let him say it, I don't believe he can say a flower!"

Cheng Biting Jin was like thunder, and he wanted to continue to go crazy, but he was forcibly dragged back by Chai Shao, and then he said to Xiao Han with a dark face: "I don't believe it, can a piece of rotten iron still be sold for the price of gold?" ”
