The strife and excitement outside seem to never affect Cheng Zhijie.

After returning from Zhenbei, Cheng Zhijie only held the position of a general of the left army.

This is actually a position of real power, one of the sixteen generals, and the status is naturally needless to say.

But for the left leader, Cheng Zhijie didn't care about it, and the two generals were all in charge, and he himself was either dozing off or looking for someone to chat, and he couldn't be more idle.

In fact, Cheng Zhijie's choice was very right, and he did not invest his energy in useless places.

The general of the left army seems to be very good, and it is also a position of real power.

In fact, with the implementation of military reform, the sixteen guards will gradually withdraw from the stage of history, to put it bluntly, the current sixteen guards, just stand on the last shift, and you don't need to worry about the rest.

The Tubo people made trouble, the Tubo people were arrested, the Tubo people were beaten, and all kinds of rumors sprung up all over Chang'an and the entire Tang Dynasty, becoming a hot topic for the people of the Tang Dynasty to talk about after dinner.

No one has ever dared to be so presumptuous in the territory of Datang, there have been before, but those people now don't know how many years they have been dead.

Outside Chang'an City, a few years ago, in exchange, Li Yuanji got the piece of land.

After a few years of abandonment, it has changed dramatically.

On hundreds of acres of land, there were strange-looking houses, the houses were very long, one was hundreds of paces long, and there was a slightly pungent white smoke at one end.

You don't have to think much about it to know that it must be the smell of the black stone after it is burned.

Blackstone, that is, coal, has now become a good business, the price is not expensive, it is easy to use, especially suitable for heating, the largest amount is in Taipingfang, where all the heating is done, and it is necessary to use blackstone for heating.

Cheng Zhijie also has a lot of money at home, which is very cheap, although it has risen a little more than before, but six hundred yuan a car, a car has the appearance of several stones, this price is still acceptable.

The people couldn't accept it, so they could only spend more physical strength and chop more firewood while the weather was still cold.

"What's that?" Pointing to a row of houses, shining places, Cheng Zhijie asked with great curiosity.

"You'll know when you get there!" Yu Ren smiled slightly and sold a pass.

There is business to the door, he is too late to be happy, the prospect of greenhouse vegetables is very good, but the market is not big, after all, there are not many people who eat.

Selling vegetables and materials, as long as they can be sold, Yu Ren is very welcome, and making money is the most important thing.

'Hiss......'

Walking closer with doubts, Cheng Zhijie couldn't help but gasp.

Still a few steps away, Cheng Zhijie could see the green vegetables inside at a glance, and the glittering things before could be seen clearly now.

Seeing this scene, Cheng Zhijie instantly had the idea of retreating, this is too extravagant, and it is not something he can play at all.

"Don't ...... Don't go! Cheng Zhijie turned from joy to sadness, turned around and left, but Yu Ren was in a hurry, and hurriedly reached out to pull.

Cheng Zhijie turned his head angrily and scolded angrily: "Why don't you leave? If you had said earlier that you would have used so many crystals, the old man wouldn't have to run this trip in vain, and it would have been good if he didn't settle accounts with you, but he dared to buy and sell it? ”

"Su Guogong, this is a crystal, but it is not a crystal, in short, this thing is not as expensive as you think." Realizing that Cheng Zhijie was scared away by so much glass, Yu Ren explained a little speechlessly.

The preciousness of the crystal can no longer be described in words, let alone such a large piece, it is a crystal artifact, which is also priceless.

To grow vegetables in a greenhouse, it takes so many crystals to use it, even Yu Ren feels that it is a waste and a luxury.

But there's no way, he didn't say anything about it, anyway, the price is already known, and it's not as expensive as imagined.

"Not that expensive? How much? Do you sell such a big piece of ten? How many come as many as you want! The old man took it all. Cheng Zhijie was angry and asked angrily.

"There's about a thousand yuan here, Su Guogong, do you think we should sign a contract first?" Just ten pieces, buy fifty pieces and give you one, and this slave and maid will be in charge. Yu Ren instantly wanted to burst out laughing happily in his heart, and secretly said How could Cheng Zhijie know that a piece of glass was ten times?

"I ......" Cheng Zhijie was about to scold, but after reminiscing, Yu Ren said that it was for sale, and he was stunned for a moment, and asked, "How much is a piece?" ”

"Selling it to Su Guogong is ten yuan, but selling it to other people, to say the least, it will cost twenty yuan! This is the price set by His Majesty himself. Yu Ren said very frankly.

"Is this really that cheap?" Feeling a little unbelievable, Cheng Zhijie couldn't help but speed up his pace and ran to look inside.

Transparent, although the transparency is not particularly high, but standing in front of it, you can basically see the opposite wall, and you can also see wisps of green vegetable leaves.

I knocked it with my hand, it was a little cool, but it was not particularly cool, there was a lot of fog in it, and I could see the old farmers who were busy.

"The old man took it from you, and then went outside to sell it, do you have any opinions?" Cheng Zhijie instantly felt as if he was going to get rich.

Ten pieces, sold for twenty pieces, changing hands is double the benefits, and this thing does not seem to be short of sales in Chang'an, and luxury goods are always not worried about buyers.

And looking at the appearance here, this crystal can be made into a window, and when the time comes, the house will be bright, how good, it is simply tailor-made for those rich people.

I was worried about how to have some fun for the emperor, but I didn't expect an accident to make me find a good idea.

"This, officials don't do business......" Yu Ren rolled his eyes and said repeatedly.

"Boring......" Cheng Zhijie waved his hand boringly.

Accompanied by Yu Ren, Cheng Zhijie walked around the entire Zhuangzi, which was very extravagant, although it was still vegetables in it, but it gave people a very tall feeling.

I turned around a few sheds and picked a lot of vegetables myself.

Give money? It is impossible to give money, even if the emperor asks about it himself, it will never be given.

I just picked some to eat at home, and I didn't pull them out and sell them, so why should I give money for the vegetables I picked with my ability?

There is heating in the greenhouse, and vegetables need a lot of water, so it feels a little damp inside, but not cold, and it would be better if there was less water.

So, Cheng Zhijie had a bold idea.

……

"What do you want the craftsman to do?" Li Yuanji asked puzzledly, today Cheng Zhijie suddenly found himself and wanted to borrow a group of craftsmen.

The craftsman is definitely a treasure now, no matter what type of craftsman, it is not enough, and Li Yuanji hates to break a craftsman in half to use it.

"Transformation, the minister went to Zhuangzi, and I had a good idea in my head, if there are no craftsmen, this thing is not good, so I will lend my majesty the craftsmen who built Zhuangzi to me one or twenty, as short as ten days, and as long as a month." Cheng Zhijie said righteously.

"Transformation? What is the transformation of the good end? Isn't your house already heated? Li Yuanji asked without turning the corner for a while.

"Crystals, use crystals to cover the entire window, how bright the room should be, I feel comfortable thinking about it." Cheng Zhijie was still immersed in his sweet dream, and immediately said: "Your Majesty said to borrow it or not, don't borrow it from the ministers to go to other places to take a look." ”

You...... You're so meowy, are you borrowing someone like that?

Using glass as a window is an idea that Li Yuanji has had for a long time, but because he has been busy with various things, he has no time to renovate.

Unexpectedly, Cheng Zhijie, who went to Zhuangzi, discovered this secret, not only discovered it, but also planned to pay for it and be the first person to eat crabs.

"Okay, one or twenty is impossible, I don't have so many people, just transfer two craftsmen over, the progress may be slower, you pick the important ones and let them do it first." After thinking about it again, Li Yuanji nodded and agreed to lend someone to Cheng Zhijie.

"Your Majesty, five? Five? The two of them are too slow......" Cheng Zhijie tried to bargain.

"If you don't leave, there will be no more!" Li Yuanji glared at this thing fiercely, he was not afraid of heaven and earth, but his ability to do death was very superb, and the angry Li Yuanji directly threatened.

"Let's go...... knowing that it is impossible to come again, Cheng Zhijie muttered secretly, then turned around and left, whether it is two people, slow is slow, it is a big deal to let the people in the house help.

Looking at Cheng Zhijie's departing figure, the corners of Li Yuanji's mouth rose slightly, revealing an evil smile, and instructed Song Zhong beside him: "Let Danian take his apprentice and tell him that if you want floor-to-ceiling windows, you can use as much glass as you can, don't save him, you must be atmospheric and high-grade." ”

"No!" Song Zhong secretly covered his mouth and smiled, and quietly retreated.

If you don't expect glass to make money, what is it for?

As the owner of the Tang Empire, Li Yuanji has conditions that no one has.

No matter what you want to do, the cost is always the lowest.

It's like this glass, which outsiders call crystal, and the price is quite expensive, but how much is this thing actually worth?

The materials are all free, and if you order them casually, a steady stream of raw materials will be shipped, and what you need to pay is just the cost of labor.

Converted, the cost of a piece of crystal is less than a hundred dollars, and it is ten pieces that change hands, and it is enough to earn a hundred times the benefit, which is still a friendship price, and if you are someone else, you have to start from 200 times.

Li Yuanji began to have some doubts, was the price he set too low?

shook his head, then picked up the brush, and wrote the word crystal on the paper on the desk, if it wasn't for Cheng Zhijie's stubble, he would have forgotten about such a good thing as crystal.

I looked at the names on the list again, and it was basically done, and now I am just waiting to get rich......
