Xiao Ginseng came out of Cang Da's arms and asked suspiciously, "What do you want these things for?"

Cang smiled weirdly: "You'll know when the time comes." ”

Then he beckoned to the fire monkey on the side and said, "Fire monkey, come over and help me make a mold." ”

The fire monkey saw that Cang Miao had something to do for him, so he hurriedly followed Cang Mang.

......

A day later, the fire monkey had already made the mold according to the vast requirements.

Two days later, with the cooperation and consultation with Xiaolei, Cangmang finally got the design of the cave mansion.

This cave house covers an area of more than ten acres, which is larger than the Zhao family in Green Water City.

Garden, pond, alchemy room, refining room, cultivation room...... All the features imaginable are the same.

Cang Mang is also preparing to open up a spiritual field next to the cave, and this spiritual field may be handed over to Liu Xian and them to take care of in the future, so it is impossible to use the chaotic spiritual liquid to frantically give birth to the plants in the spiritual field.

He was still the same, leaving himself a small piece of land in the back garden, and if he needed something, he would grow it himself.

This time, the cave has specially designed a very special place.

Xiao Lei plans to open a stone cave at the foot of the mountain near the cemetery, which is a special cultivation place for the five of them.

After studying the formation of the Extreme Yin Land, Xiao Lei has already produced some experience.

Combined with the knowledge she had learned before, she redesigned a formation and prepared to practice it in this cave.

And the entire cave mansion, under Xiao Lei's arrangement, also faintly formed a larger formation.

......

Liu Xian and the others had already found what he needed for Cangmang, and a cart of white sand was piled up outside the Xianya Residence.

Sand, limestone and soda ash were prepared for the purpose of making glass.

As far as he can remember, glass is a good thing.

In this world, those high-level refiners can refine all kinds of strange and strange magic weapons, but no one really makes glass.

The doors and windows of all the houses here are still framed with cotton paper, so the light transmittance and other aspects are much worse, and you can't see the outside of the house directly from the inside of the house, which is very long and unaccustomed.

Now that he wanted to build a cave for himself, he decided that he must make glass.

With this thing, not to mention the shelter from the wind and rain, the lighting should be much better, and there is no need to light up the house during the day as in the past.

......

A group of disciples appeared outside Xianyaju.

"May I ask if Senior Brother Cang is at home?"

Cang Mang personally opened the courtyard door: "You are?"

"I've seen Senior Brother Cang, we are here to build a cave for you. ”

"Come in, please. ”

Cang Mang beckoned the disciples to sit down in the courtyard, and then took out the design drawings he and Xiao Lei had made.

In these plans, there is the plan of the entire cave house, as well as the shape and structure of all the houses.

The overall structure of the yard was designed by Xiaolei, and most of these house structures are designed with reference to the house structure on the earth.

"Come and see, can these drawings be covered?"

The disciples gathered around the stone table and began to study the small stack of drawings that Cang Man had taken out.

When they saw the design of the windows and skylights, they were all confused.

The windows are better to understand, but what is the skylight?

"Senior brother, what is this?"

"Oh, it's called a skylight. ”

"What about the skylight? What if it rains? Isn't it to make a cover on this skylight, or to arrange a formation to avoid water?"

Thinking of this, these disciples suddenly realized that they all praised: "The design of this skylight is really great! In this way, when it is not raining, the room will be very bright." ”

"Well, it's the first time I've seen this kind of design, Senior Brother Cang is really talented. ”

Several disciples began to discuss and even began to study how to design this skylight, their faces full of excitement.

Cang Mang said on the side: "This skylight is not so complicated, and you only need to install a piece of glass on it when the time comes." ”

Several disciples widened their eyes, you look at me, I look at you, and they all whispered to each other, "What is glass?"

Everyone shook their heads and didn't know.

Cang Mang continued: "You don't have to worry about the glass matter for now, let me ask, apart from these windows, can the cave house be constructed according to the drawings?"

Immediately, several disciples said, "No problem, I guarantee that it will be exactly the same as in the picture." ”

Cang Mang was very satisfied with this answer: "Okay, you come with me, I will show you what glass is now." ”

It's not just these disciples who are curious, they have been selling it for so many days, even Xiao Huang and they are very curious about what this glass is.

A group of people squeezed into the refining room, which was not spacious, with everything to be used, and Cangman had already prepared it.

Next, the Vast opened the earth fire and placed the cauldron on top of the earth fire.

He didn't make glass himself, but he knew how glass was made in theory, so he didn't know the proportion of ingredients.

Anyway, put more sand and less limestone and soda ash.

As the fire heated, the sand and other substances in the crucible gradually melted, turning into a warm yellow mass like melted sugar.

Seeing this mass of things, Cang Mang can basically be sure that he can successfully make glass this time.

Under the continuous high temperature, Cang Mang used some simple refining techniques to remove the impurities in the solution.

The solution in the crucible was then moved to the mold that had been prepared earlier.

When the two molds are pressed, the solution is covered in the grooves of the mold like ointment.

Cang Mang cleaned up the spilled glass solution and threw it back into the crucible, allowing it to heat up inside.

And he reopened the mold, and the glass solution that was like a warm yellow before had now turned dark red.

Cang Miao didn't know any cooling technology, so he could only let it cool down naturally.

Everyone watched as the contents of the mold changed from warm yellow to dark red, then slightly blackened, and now completely transparent.

After the glass in the mold has cooled completely, it is taken out.

The whole piece of glass is crystal clear, like a piece of thin ice without a little bubble, gently bumping into it, making a crisp sound.

Everyone looked at the thing in their hands, and they all couldn't close their mouths.

Several disciples asked curiously, "This ...... This is glass?!"

For the first time he successfully made the glass, Cang Mang was also very satisfied, and after seeing the surprised expressions of Xiaolei and the fire monkey on the side, a burst of pride rose in his heart.

He didn't know much about refining weapons, but through the simplest method, he made something that would surprise everyone.

Finally, someone spoke: "This thing is so beautiful, better than jade." ”

The people around nodded in agreement, agreeing with this conclusion. Take a hundred plating to read the latest chapter of "Peerless Soul Seal Claw Book House" for free for the first time.
