Then there is gunpowder, which is also one of the four great inventions, it is not difficult to get it, as long as you find sulfur, saltpeter, and charcoal in proportion, of course, he still knows one or two of the proportions.

Although this is the simplest gunpowder, it is a rarity in Daqin.

Of course, it would be better if he could make black powder, but he wouldn't.

Ay! It's still a lack of knowledge! Li Zhao shook his head and sighed.

Soon, he asked his servants to buy the raw materials, but he drew the drawings.

In fact, he doesn't need to prepare too much, there is still a lot of smelted iron when making air guns, or wrought iron of excellent quality, which can be used as the main raw material, as for bullets! The best material is a mixture of broken glass and iron beads, but glass has not yet appeared in Daqin, so it can only retreat to the next best thing and use small iron beads for the time being.

Two days later, a shop in a not very prosperous area of Xianyang City opened.

Unlike the other shops, this shop is not an ordinary thing, it looks very strange, it is actually a thin, yellowed, boxy thing, this thing looks very strange.

And the shopkeeper is Xiao He.

After a simple opening ceremony, the sale began.

In front of the door, two slaves were shouting vigorously.

"Sell paper! Freshly baked paper, a good thing to write. ”

This shouting did attract a lot of people, but there were many people watching the freshness, but there were no purchases.

Xiao He was doing business for the first time, and he didn't have much experience, and when he saw someone coming, he took out a piece of paper to show off, as if to say, this thing can change your fate.

However, the people of Great Qin had never seen such a thing, so how could they believe his nonsense.

At this moment, there is a boy who is slowly walking with a fan, he is Gao Fugui.

Since the last time I bought jade and lost most of my father's wealth, I was locked up by my father for several days, and I was able to come out recently, but when I think of jade that I bought at a high price but had to sell it at a low price, I feel very uncomfortable.

But he is not discouraged, he always believes that his investment idea is correct, investment! It's normal to have profits and losses, and if you lost last time, maybe you can find an opportunity and earn it back.

As he walked, he didn't know how many streets he walked, and suddenly, he heard a shout: Sell paper!

When I looked up again, there were many people around there, and I was suddenly curious: paper? What is it?

Driven by curiosity, he came to the door of the store and saw Xiao He swinging with a stack of papers, talking about how precious this thing was.

But this thing is too rare, no one has ever seen it, even if Xiao He said a lot of fanciful, no one bought it, but there were many teasers.

"Shopkeeper, it's useless to just talk, you say that this thing can be written, but you can write it!"

Paper is precious, even if it is a waste of Xiao He, it is impossible to write it, unless someone buys it.

"This guest officer, if you buy a stack, I can give it a try."

Xiao He explained.

This caused laughter.

"Shopkeeper, I bought it but it was waste, that's not a waste."

"That's right! I don't dare to try this, it must be a lie! ”

"That's right, the thing that can be written is a bamboo roll, and this thing will break when it is rubbed, can it be written? Don't fool me and other readers. ”

"Give it a try, or I won't be able to buy it."

The laughter was louder.

Xiao He has never encountered such a difficulty, and he is in a dilemma for a while, to try or not to try?

He knows how reliable paper is, but no one else knows!

In the end, he was still ruthless and ready to give it a try, if he wanted to trap the wolf, he had to put down some money!

So he took out a piece of paper, and was about to put pen to paper, when suddenly I don't know whose fan came to me, maybe with too much force, and actually slapped the paper in half.

Suddenly, everyone laughed again, this thing was too unbearable.

Someone smiled with anger and asked, "Shopkeeper, isn't this a lie?" How can there be a written thing that will be broken when touched, and the writer, the save, can this thing retain the geometry? If a precious book is written on it, but it is broken, will it not be destroyed, and this thing will be wasted? ”

What's more, he said: "Although this thing is cheap, it is thousands of miles worse than bamboo rolls, everyone, don't be fooled." ”

"You, vexatious?" Xiao He looked at the troublemaker angrily and reprimanded.

"What? Lies debunked and angry? Hey! This thing is ridiculous, even if it is given away, people don't have to, close the door as soon as possible! ”

The man was sarcastic.

However, at this moment, an incongruous voice was heard.

"You don't, I want it."

The person who spoke was Gao Fugui, and he walked over. In fact, he looked at it for a while, and what others couldn't see, he saw.

He is not mindless, but deliberate.

At present, on the occasion of the imperial examination, a large number of scholars have emerged. There is definitely a need for writing, and now more bamboo rolls, cloth and the like are used to write, but these things are expensive, a cheap bamboo roll has to be dozens of Qin and a half taels, and the fabric is more expensive.

Of course, bamboo rolls can't afford either.

But this rare thing is different, judging from the price tag, it only costs half a Qin and a half tael, which means that one Qin and a half tael can buy two.

Regardless of how many words can be written, the price will be very popular, at least poor students can afford it.

"Yes, it's a poor student." He thought of the key, at this moment, these people are all powerful families, so naturally they don't have to worry about money, but they are worried!

There are thousands of poor students, if one person buys some, wouldn't there be a particularly large demand, and the amount of paper at the moment is not much.

At this moment, before he could see clearly what paper was, a business opportunity was born in his heart.

He's going to buy them all.

The last time the price of jade fluctuated, he experienced it first, first the price fell to the bottom, and then soared to the peak, what is the reason? It's not because there has been a shortage of jade for a while, but at the moment this thing is rare, isn't it a shortage?

Hearing someone say that he wanted to buy it, Xiao He's eyes lit up, and he asked, "How much do you want?" ”

"I want them all."

Gao Fugui looks very arrogant.

Xiao He couldn't believe his ears, others had been watching for so long, and they were still ridiculed, but no one bought it, this person was good, he didn't ask for anything as soon as he came.

Rare guest!

However, Xiao He is a sincere person, and asked carefully: "Don't you need to see the finished product?" ”

Gao Fugui waved his hand, looking very indifferent, "No need, just pack it for me and send someone to my house." ”

Xiao He was very satisfied, his eyes narrowed into a slit with a smile, and at this moment, people seemed to see a profiteer being born, and he hurriedly ordered the slaves:

"Didn't you hear? Prepare it for your guests, and you will deliver it to your house in person. ”

The servant smiled and hurriedly prepared to go.

They didn't expect that within a short time of opening, all the finished products would be sold, which was unexpected!

Xiao He was happy, but the ridicule of the onlookers made him rich.

"Huh! Isn't this the son of the Gao Coordinator family? Is he crazy, a discerning person knows at a glance that this is a fraudulent thing, he just bought it all, does he have money and nowhere to spend it? ”

Someone knew Gao Fugui, so he whispered, "Hehe! You don't know! This son is the son of a Gao family, and it is normal to behave like this. ”

"What was more ridiculous some time ago?"

"Oh!" Someone was interested, but they didn't mean to lower their voices, "What nonsense?" ”

"Hey, hey! Remember jade? He actually bought a lot of jade in large quantities when the price of jade was high, no, in the end, he lost most of Gao Xie's family wealth, and was closed by Gao Xieshi for several days! It's not ridiculous or anything. ”

"That's it! What a loser! Looks like he's going to die again this time. The man covered his mouth and smiled, "I really don't have any eyesight." ”

"Just wait to see the show! This time, the high co-ordinator didn't know how to punish him. ”

Gao Fugui naturally heard these people's discussions, but he didn't care. Invest! Some arguments are normal.

He doesn't believe that every investment is so unlucky.
