Half a night, Li Feng and Xie Yingdeng returned to the small temple near Longquan Village together and found a sign had been hung with three big words "Qingyun Temple". It seems that these Taoist masters are also quite nostalgic.

This Qingyun Temple is still under renovation, but the project is about to end, so there is no problem with the residence. Here will be a secret research base in the future.

When I entered the hall, I found that it was empty and there was not even a statue of a god. Originally, this was a temple, so the original Bodhisattvas and other things were invited out. The statue of Taoist ancestors has not been completed yet.

There are several backpacks on the ground, filled with pieces of coke with blue luster, and the quality is actually good. It seems that the coke oven is quite easy to use and can continue to expand the production scale.

Not only is the coke ready, but the large crucible that Li Feng asked to fire in the past few days has been made. These Taoist masters are indeed capable of "refining".

The sand was also prepared, dug out from the deep soil, and washed according to Li Feng's requirements to remove impurities such as clay contained in it.

Li Feng grabbed a handful of sand and the sand flowed down his fingers, very loose; there were also prepared lime and soda ash, which were not difficult for Taoist priests who were the main business of alchemy.

Everyone started to move the things outdoors, filled with coke in a thick iron furnace, and someone took turns blowing the air next to it.

Put a crucible on top of the stove and add the mixed raw materials, and the rest will boil.

The sky soon became dark, but the courtyard of Qingyun Temple was still prosperous. Accompanied by the sound of yelling blowing, the fire was red, and the Taoist men around him were sweating profusely, but they still refused to go away and all came to observe.

Li Feng was convinced by these Taoist masters, and they were really dedicated. However, the melting point of the sand is relatively high, and we have to wait for a while.

"Brother Feng, why haven't it melted yet?" When Xiao Kezi asked the tenth time, the sand in the crucible finally turned into liquid. At this time, the moon was already in the middle of the sky, and it was midnight.

Even so, the Taoist priests were still energetic, their eyes were red, and they watched Li Feng reach a hollow iron pipe into the crucible that had been brought to the ground and began to stir.

Li Feng is now fully armed, wearing thick gloves on his hands and a cotton hat on his head, covering his face.

"The stirring step is very important, which can greatly reduce bubbles." Li Feng said, changing an iron tube and taking some slightly condensed glass frit, just like picking noodles.

Then, he bulged his cheeks and started to blow in slowly. Then, something that made the Taoist man widen his eyes happened, and the glass frit at the front of the iron pipe began to slowly expand, becoming thinner and thinner and more transparent.

The people standing on both sides even saw the surprised expression of the person opposite through the two layers of glass: the glass bottle is getting bigger and bigger, and the eyes are getting bigger and bigger—

"Wow, Brother Feng, you are so awesome!" Xie Yingdeng also quickly turned into "Wind Blow".

The guy was still stretching out his hands, his eyes full of intoxicating light, reaching towards the exquisite glass bottle.

It scared Li Feng, quickly stopped blowing, and shouted: "Hot!"

Still one step later, Xie Yingdeng touched the glass bottle with both hands, immediately turned away from the fire, and then put it to his mouth to blow air. At this time, the glass bottle was several hundred degrees Celsius, so how could it be touched casually?

While the glass bottle had not yet completely cooled down, Li Feng quickly flattened the bottom, so that a crude glass bottle would be blown.

Although in Li Feng's opinion, the shape is not so uniform, a bit flat and unrounded, and the bottle mouth needs to be heated to make it smoother; but in the eyes of Taoists, this is simply the most exquisite treasure in the world, more precious than the best jade.

The fact is indeed similar. In the early stages of glass production, the price was on the same level as gemstones.

You can't hold it in your hands and play with it carefully, so everyone just watches it. Against the backdrop of the torch, the glass bottle is crystal clear and pure and flawless. It's simply beautiful and can't even look at it.

As I watched, I heard a crisp sound, the glass bottle broke, and the people around me felt that at this moment, my heart was also broken.

"Who, who broke it!" A roar sounded in the courtyard, as if he was about to eat people.

It is simply too tragic to call the best thing broken. The fragile glass heart of Taoists cannot bear it.

In the corner, Xiao Kezi's weak voice came: "It's really not me--"

This guy also knows that he is usually naughty, but he really didn't do it this time.

At this time, Li Feng said: "The glass bottle is broken by itself. This kind of glass products are naturally cooled at room temperature. The glass products are easy to break, so you still need to have matching fire-fighting equipment."

"How to do it?" The men all surrounded him like a baby and began to ask.

Li Feng briefly introduced the division into different temperature points, and then let the glass products slowly cool at different stages. This process is called fire fading.

Afterwards, Li Feng pointed out some theoretical things: for example, you can first blow some experimental tools in the treasure book, such as flask test tubes, and practice your hands first.

For example, when blowing, it can be quickly changed into various shapes according to needs, and even preset molds, etc. Of course, it can also be stretched into flat panels, then made into glass windows or mirrors, etc. Also, you need to find ways to expand production in the future, etc.

After saying that, he couldn't hold on and went to bed yawning.

The Taoist man's glass heart was broken again: "You said that using such precious glass to paste windows is too expensive, it is really too expensive!"

Li Feng couldn't do everything himself. In that case, even the great Mr. Zhuge couldn't hold on, let alone an ordinary person like him. So, usually, he just proposed a plan and tried to leave the rest to others. This is also a good exercise, right?

Li Feng still knows this truth by practicing it.

He believed that with the almost crazy persistence of these Taoist men, as long as they are deceived by him - leading to the right path, they will definitely burst out with powerful power.

The next day, Li Feng got up a little late, but he had to continue practicing morning exercises. Everything is important to persist, and he should not waste a day.

After packing up, I just came out to the yard and saw a group of Taoist masters gathering around and fiddling. My eyes were red, but my spirit was still very strong, just like I had just knocked on the Nine-Turn Golden Pill.

After a few words of advice, no one listened to him. Li Feng shook his head and could only run out of Qingyun Temple. Running on the road, there were busy scenes everywhere. Needless to say, the fields had already plowed oxen and walked around.

On the road, you can occasionally see coal trucks. When they ran to the other side of the coal mountain, a large group of laborers were already digging brick kilns.

Burning out the glass also increased Li Feng's confidence: burn more glazed tiles at that time, Yang Guang would spend a lot of money. If he didn't make a fortune, he would be sorry for Yang Guang's ambitions!

When he ran back to Qingyun Temple, Xie Hong, Yuan Tiangang and Huang Guanzi were each holding a glass bottle in his arms: "Dalang, I burned it all night, and in the end, these three finished products are left. Why not take it first and sell it to the rich, exchange some scientific research funds, and we purchase raw materials, but we have no money again-"

Li Feng looked at these three people, holding the glass bottle, with a painful look on his face, but he had to bear the pain of giving up. He couldn't help but want to laugh: It's a little progress, and finally I understand the principle of economics first, so I'll be disrespectful.

Taking advantage of the fact that glass products have just emerged, they will first launch a small amount to the market and make a big profit; when it spreads in the future, the things that are bullish on the street will be worthless.

However, Li Feng must not take the lead in selling this matter. After a year, the original hundreds of coins of things were not worth even if they were worth the money. Do you think the person who bought it will fight to Li Feng?
