"Uncle Master."

"What do we have to do with so much sand?"

Xiaobidong was still very happy to see so many piles of sand.

She suddenly realized that drilling sand piles is also a very fun game.

There is no geological structure of the beach around Bailu Mountain. If you want to play, you can only go to the nearby sea.

On ordinary beaches, there is no such delicate sand.

Now that there is so much sand on Bailu Mountain, do a little trick, get some rain and wet the sand, so you can easily use them to play games.

Xiaobidong has already done this. She used this wet sand to build many buildings of different colors, castles, towers and caves, etc., and had a lot of fun.

"I want to try to use these sands to refine five-color stones."

"If you can succeed, you don't need to go deep into the Chaos Sea to collect the Five-Colored Stones."

Wang Yinguo grabbed a handful of sand, checked the components and structures, and said to Xiaobidong.

"What?"

"Can sand be refined into five-color stones?!"

After hearing Wang Yinguo's words, Xiaobidong and Bai Ze, Xiaoyun Monster, Xiaolong Aozhou and others around him were all shocked.

They followed Wang Yanyu and went to Chaos Sea together, so of course they knew it was difficult to collect the five-colored stones.

If the True Ru King Cause and Effect said, the five-color stones can be prepared by using sand, and if they succeed, it will save everyone a lot of time and energy.

"This is a big thing that benefits the prehistoric world!"

"Sure enough, if you do anything at will, you will shock the entire prehistoric world!"

Bai Ze couldn't help but sigh.

"No wonder my uncle came back with a five-color stone. Is he going to make a sample?"

Xiaoyun Monster's eyes were particularly pointed, and he was the only one among the people who noticed this.

"Ha ha!"

"That's true. I need a sample to analyze whether I can refine qualified five-color stones!"

After hearing Xiao Yunqian's words, Wang Yinguo took out the five-colored stone he left behind, nodded with a smile and replied.

"grandfather."

"This matter must be difficult, right?"

Xiaobi looked at the sand and then at the five-colored stones in Wang Yinguo's hand, and suddenly felt that this matter was as difficult as climbing to the sky.

It is not easy to look at this randomly visible sand into a five-color stone emitting a dazzling light.

God knows what the uncle Wang Yanguo thought, but he actually had such a wild idea?

“It’s not very difficult.”

"It's just that the process is a bit complicated and needs attention to details."

"I guess it's better to try it a few more times."

Wang Yinguo didn't expect that one day he would make monocrystalline silicon himself, and it was in this prehistoric world.

If it weren't for the systematic analysis of the composition of the five-color stone and giving a clear component explanation, Wang Yanguo wouldn't believe that the raw material for Saint Nuwa's stone refining and repairing the sky was actually a single crystal silicon with extremely high purity.

"I'll help the uncle!"

Bai Ze actively made a request to Wang Yinuo to participate.

"good!"

Wang Yinu nodded.

Although Bai Ze could not do anything specific, he walked around here twice a day and said some blessings, even if he helped a lot. This is the meaning of the existence of the head of the auspicious beast in the prehistoric world.

Monkey Xiaojin is of course one of the main forces in refining the five-color stone. After all, it has had many successful experience in alchemy and is very serious in doing things. It is a reliable and skilled worker.

The group of calf demons led by Niu Mengniu Gang are also subordinates that Wang Yanyu can rely on. Although they are not creative enough, they have strong execution ability and can be used as tool bulls, so they don’t have to worry about creating chaos.

"Uncle Master."

"I want to join in, and do my best."

Xiaolong Aozhou also needs to participate in the project of refining five-color stones.

"What can you do?"

Wang Yanyu asked.

"I'm good at spitting out water and fire."

"If you want to refine elixirs, don't you all need these two things?"

Xiaolong Aozhou replied.

“That’s right.”

"That's yours."

Wang Yinguo nodded and agreed to Xiaolong Aozhou's joining.

In fact, in the process of preparing single crystal silicon, heating and water cooling are indeed needed. Xiaolong Aozhou's talented magical powers should be used in this process.

“I want to join too.”

The stone man Zhou Xiaoping also asked.

As a model for the enlightenment of stones to become spirits, the existence of the stone man Zhou Xiaoping can itself clear the minds of the people around you and produce many magical and effective ideas.

Based on this reason, Wang Yinguo nodded in agreement.

In short, this is a major event that benefits the people of the world. The more people join, the better.

At least, they can get some merits in this matter.

"grandfather."

"Does all these sand be used up?"

Xiaobidong was a little reluctant to let go of the various artworks she made on the sand pile.

"That's not."

“I just have to use a small part of it.”

"For other sand, you can find a place to save it, build a small lake, build a beach, etc., which can also be regarded as decorating the scenery of Egret Mountain and adding a game place."

Of course, Wang Yinguo knew what Xiaobidong wanted, so he said generously.

"Very good!"

"There will be sand to play in the future!"

After hearing this, Xiaobidong's enthusiasm for work increased by more than 200%.

"Uncle Master."

"How many alchemy furnaces are needed this time?"

"The number of Bagua alchemy furnaces we have grown is not very enough."

Monkey Xiaojin looked at the piles of sand, but he felt a little worried.

The capacity of the alchemy furnace is very limited and cannot hold so much sand at all.

"This time, we don't need to use the Bagua Alchemy Furnace."

"We need to make some special containers to prepare five-color stone (mono-crystal silicon)."

Wang Yinguo shook his head and comforted the monkey Xiaojin.

To refine elixirs, of course, you must choose the Bagua alchemy furnace.

However, when preparing things like five-color stones (mono-crystal silicon), there is no need for high-end, atmospheric and high-end Bagua alchemy furnaces. Instead, Wang Yanguo needs to make some equipment such as quartz crucibles and glass separators, and also make some special closed containers, etc. These things are the main force in refining five-color stones.

Fortunately, Wang Yinguo probably knows a little about the production process of these things.

In his current environment, it is not difficult to create such an assembly line.

After all, this is a world where immortal cultivators exist.

Wang Yanyuan only needs to have a complete idea to produce these main equipment. As for other details, it needs to be carefully experienced during the experiment and gradually improved.

The main component of sand is silica.

To obtain crude silicon, the first thing to do is to react silica and coke at high temperatures.

However, crude silicon contains a lot of impurities and cannot be used directly, so purification is needed, mainly to react with crude silicon and chlorine to form a silicon tetrachloride solution.

Then, by using fractionation technology, relatively pure silicon tetrachloride can be obtained.

Finally, by reducing the hydrogen gas with silicon tetrachloride, a relatively pure polycrystalline silicon can be obtained.
