"So that's how it looks, teacher, but what is this glass? Why have I never heard of it?"

He nodded his head without understanding. In short, one principle is not to argue with the teacher. If you don’t understand, ask. It’s no big deal.

"I can't explain this to you for a while. Let's take the tools and go out to find materials!"

When Li Zhi heard Xiaocheng's question, his head instantly grew bigger. This guy, when he was with this little guy, seemed to have to review the 100,000 whys soon.

"Teacher, didn't you say you were looking for materials? What did you do when you ran into the river to dig sand?"

Originally, Xiaocheng was holding the tools and followed the teacher to look for materials with great enthusiasm. Unexpectedly, after just a few steps out, the teacher had already entered the river and started digging sand.

"Have you never seen glass? Then today I will give you a good experience of how glass is made!"

Although Li Zhi was talking, his hands did not stop at all, and he kept throwing the fine sand in the river towards the shore.

Xiaocheng was even more confused. The teacher could compare glass with crystals. Obviously, this glass would also be a very precious material. But now the teacher is making sand and is still making glass. Xiaocheng thinks that the teacher is teasing himself no matter how he thinks.

However, the teacher did it himself, so he naturally had no reason to stand by and watch, rolled up his pants and entered the river, helping the teacher dig the fine sand in the river.

In a blink of an eye, two hours passed. Looking at the small pile of sand on the shore, Xiaocheng was in tears. He thought it would be a very happy thing to find materials, but he never expected that he would use this method to find materials.

Throwing the shovel in his hand aside, Xiaocheng sat directly on the stone beside him, gasping for breath. Although his body was much stronger than his peers, he was still there and had already reached his limit after doing so much work.

"It's not bad, thanks to your help, otherwise, I don't know when I will dig it."

Seeing the little guy being so tired, Li Zhi grinned and said, "He could clearly feel the kindness of Xiaocheng to him, so he would spare no effort to teach this child, which can be regarded as helping him change his destiny for poverty."

"Teacher... is this thing the material for making glass?"

Xiaocheng asked pantingly. Until now, he didn't believe that these useless sand could make other things.

"I can use all the remaining things except these tiny stones inside!"

While speaking, Li Zhi took a bamboo basket at some point. While picking out the stones in the fine sand, he put the fine sand into the bamboo basket.

"Let's go, these should be almost done!"

Looking at most of the basket of fine sand, Li Zhi nodded with satisfaction, squatted down slightly, raised the fine sand, turned around and greeted him, and walked directly to the inner courtyard.

In the deepest part of the manor, there are messy materials piled up in a huge warehouse. The things here belong to Li Zhi and Xiaocheng. When they learn theory and draw drawings every day, they will be in the room, but when it comes to actual operation, they will come here.

"Teacher, what's the use of this sand?"

Seeing that the teacher really brought him to the laboratory, Xiao Cheng felt a stir in his heart, and these useless broken sands, he didn't believe that the teacher could turn them into flowers.

"Populate the sand into the pot, and I will go and light the fire!"

After giving a casual command, Li Zhi walked outside, and he had to look for something flammable and hot.

“Can this thing be stewed?”

After hearing Li Zhi's words, Xiaocheng muttered dissatisfiedly, but he did not dare to ask questions and could only act as the teacher's instructions.

"You must be patient in making glass and don't underestimate every item in this world. Just like these fine sand, who can imagine that it can also be made into crystal clear glass."

Seeing Xiaocheng's impatient expression, Li Zhi shook his head slowly and added some wood to the bottom of the pot from time to time, then he said earnestly.

Perhaps it was because my body was really tired when I was salvaging the sand. Under the instinct of the fire, Xiaocheng felt that his eyelids became heavier.

As the temperature in the iron pot became higher and higher, a little crystal began to appear at the bottom of the iron pot, and then the gray sand turned white little by little. Even due to the stirring, these crystals were like liquids, drifting with the flow.

"Teacher...How come this...you aren't you secretly changing things!"

Xiaocheng, who was sleepy, suddenly looked up at the iron pot, and then his eyes widened. He clearly remembered that the iron pot was filled with fine sand. After a short snatch, he had become like this. It was incredible.

"Do you need to deceive me? After all the sand in the pot melts, put it in the prepared mold, so that we will be done!"

After hearing Xiaocheng's words, Li Zhi showed a faint smile. It was normal for Xiaocheng to not understand such changes.

"Teacher, is there really sand inside? The sand we just salvaged?"

Xiaocheng looked at the liquid in the pot in disbelief. He never dreamed that the sand could have such a big change.

As all the liquid in the iron pot turned red, Li Zhi then took an iron scoop and scooped the liquid in the pot into the prepared mold.

However, when the liquid at high temperature touched the mold, it kept emitting black smoke, and even a lot of liquid dripped to the side. Xiaocheng went up several times to catch the liquid, but was stopped by Li Zhi.

"Teacher, is this the glass in your mouth? That existence that can be compared with crystal?"

As the miracle witnessed happened, Xiaocheng's thoughts became active again. Since it could be comparable to crystal, it was naturally more precious. The materials were so simple that if more were produced, it would bring a lot of profits.

"There is no comparison between the two. Crystals are naturally formed, and their preciousness cannot be generalized. Although the manufacturing method of glass is simple, and its aesthetic level is even more beautiful than that of crystals, in terms of price, it is definitely a difference between heaven and earth."
