In mid-December, the number of tourists led by Xingchen once again exceeded 30,000, and Grandpa Fu smiled so hard that he couldn't close his mouth. Now it's less than half a month since the Ice and Snow Festival, and all the tourists from the Qiankun Empire were still there. The four kingdoms and the Orc Alliance did not arrive. The number of tourists could double again in late December. The number of 60,000 tourists is approaching the limit of the reception of Xingchen.

Not to mention this, more than half of the tourists who came will not leave for a short time, because the winter catch will follow.

The entire Xingchen Collar was like a machine that was winding up. It became busy again. A large number of supplies were transported from outside every day. Mei'er was so busy that it was not easy for Jiang Xingchen to see her.

For tourists, they are completely immersed in fun and enjoyment, delicious food, fun, and the ice and snow world called miracles. Although many areas of the empire have suffered floods this year, everyone who can come is from those who have not been affected. After holding it in for a year, it is so satisfying to spend money.

The wolf pulls five yellow crystal coins for the sled, and ten yellow crystal coins for the ticket to the Ice and Snow World. There are hundreds of painters in it. It costs fifty yellow crystal coins to draw a painting by the ice lamp, which is not too expensive for these tourists.

The wasteland heading to the snow world has been crushed out of the road, hundreds of small sledges shuttle back and forth, and laughter and joy resound throughout the wasteland.

"Geehhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

The second prince had a dark face, and his muscles were thrusting wildly. I am a human being, not a wild wolf. He is now confused. Why did the father agree to his younger sister's request and ask him to take her to Xingchen to play.

"Little sister, I am also the second prince of the empire after all. Don't be heard so loudly, it will damage the empire's face!" The second prince said to the sixth prince in a low voice.

"Tsk! You said you are stupid but you don't admit it. You are dissatisfied and yelled that who will know our identity?" The Sixth Princess glanced at the second prince with contempt.

The second prince was speechless and could only have a bitter face, and shed tears silently. He was almost tortured by the way. He was not allowed to fight back when playing snowball fights, and he couldn't hide quickly... He had to stand on the side as if he had made a snowman. In the end, his legs were stiff and the aisle was struggling.

The only thing that made the second prince happy was that the Xingchen Collar was really good. It was the first time he used hot water showers and soap. He had never used such a luxurious thing in the palace to wipe his butt.

Moreover, the living in the house is comfortable, and the paper-paste windows are very bright. I sat on the warm kang and got a pot of liquor. A few side dishes were so enjoyable.

Not to mention what you eat, the food here is famous all over the world, and the signature dishes of major restaurants cannot be eaten anywhere else.

"If there was no such girl, it would be nice to come to Xingchen Collector!" the second prince thought silently.

"Second brother, let's see the ice and snow world today, go in during the day and come out at night. This way you can spend a portion of money and see two beautiful scenery..."

The Sixth Princess patted the Second Prince, showing her expression that I was very smart. Come and praise me.

The second prince suddenly felt full of fear and shouted in his heart: "Little sister, are you trying to experience the life of a civilian? The ticket price of ten yellow crystal coins is just that. You have to freeze outside for a whole day, and at night... let people live!"

"Why are you doing this expression? Do you disagree?" The Sixth Princess had a stern face and patted the second prince.

"Agree, haha, agree..." The second prince smiled so uglier than crying. Do you dare to disagree? You can come up with a more ruthless trick just by saying no.

"Just agree. Let's watch the ice lantern today and go to the amusement park tomorrow! Second brother, take me to play with ice sleds, and then go to bungee jump..."

"Ouch~" The second prince's legs became weak and he almost sat outside the sled. Since he fell off the kite last time, he has been afraid of heights and asked him to play with ice sleds and bungee jumps. Isn't this a fatal blow?

He really regretted it at this time. If he had known this, he would have agreed to pull the sled at the beginning. Why bother to suffer this?

"Second brother, what's wrong with you? Why are you doing with a drooping face and laughing to show me!" The Sixth Princess said again.

"I'm going!" The veins burst out from the second prince's neck, and he felt the urge to go wild!

Behind the two of them, the great worshipper who protected them, saw this scene, and his old face couldn't help but snatch it twice. This is not the Sixth Princess, she is simply a little witch. She has been trying to make trouble and the second prince is considered a tragic...

The arrival of the second prince and the sixth princess did not attract others' attention, at least Jiang Xingchen and Marshal and others knew about it.

After two days of playing, the four commanders of Wu Tianfeng, Wei Ning, Chen Xuangan and Dingbei Hou left first, and they could not leave the legion for a long time.

The marshal, old marquis, Feng Xuanzhang, and Wang Shuangyang stayed in the house every day, playing mahjong, drinking tea, or just squeezing cups and starting a real vacation.

Dafuteng was taken by Zhao Danqing to handle the tattoo shop, and was preparing to take advantage of the stars to open the business as soon as possible.

After accompanying him for two days, Jiang Xingchen finally made time to go to the research institute to study the problem of refractory materials with Xianning.

Before the experiment was carried out, the first problem arose. The materials collected by Jiang Xingchen were not good. The high temperatures of more than 1,400 degrees will melt, and the kiln is unstable, making it easy to have safety incidents.

Not to mention that if you want to burn glass liquid, a crucible is essential. To make a crucible that is resistant to high temperatures, you must also ensure that it cannot react with the glass liquid... Now that you can't even make the refractory bricks for building kilns, how can you make a crucible?

The experiment was in a deadlock, and Jiang Xingchen could not think of a solution for a while.

"Xingchen, let's do it, I'll continue to look for materials here! You go to the world's business and ask them to find some purple gold to try. Isn't the temperature of purple gold required? " Xianning suggested that

"Purple financialization is about 1,400 degrees!" Jiang Xingchen said in his heart that he could feel the specific temperature. But Xian Ning didn't know that there was only the concept of temperature in his mind, no specific numbers.

Of course, Jiang Xingchen could not explain this to Xianning and nodded and left the research institute.

Jiang Xingchen knew in his heart that the melting point of ordinary metals is very high, and pure iron seems to require more than 1,500 degrees. In other words, purple gold may not be pure single, and can melt at around 1,400 degrees.

Although he understands this principle, pure iron may not be effective, because he is not sure whether it is enough to burn the glass liquid for 1,500 degrees. In the end, he has to find more refractory metals or materials.

Back in the new town, Jiang Xingchen immediately found the old man and asked if there was any metal that needed higher temperatures than Zijin.

The old man was a little surprised and asked, "Not only does this kind of metal have a small amount, it doesn't have much effect yet, because it can't be melted and built weapons at all. What are you going to do?"

"Don't worry about what you do. Tell me quickly which metals are there, which one is the best to find!" Jiang Xingchen asked quickly.

The old man originally wanted to take it, but when he saw Jiang Xingchen's serious look, he knew that he could not joke, and said, "Red tin, ingot, water gold..."

The old man said seven or eight kinds in one breath, and finally said: "These are all unmelting, and none of them are easy to find. These are basically natural materials, and there is no mine at all. Anyone with these metals is treated as collections and generally they will not be sold!"

Jiang Xingchen didn't say much, and wrote a letter to Qin Manwu, asking her to help.

But in just two days, Qin Manwu's reply arrived, and these metal world stores did not have them, but they had already sent a message to acquire them, but I just didn't know if they could receive them.

When Jiang Xingchen saw the reply, he could only smile helplessly. As early as when he decided to produce glass, he considered this issue and did a lot of work and sent people to find materials. However, he did not expect that the soda ash had been shipped, and the problem of refractory materials had not been solved yet, so he could not even do an experiment...

On December 20th, Jiang Xingchen received another letter from Qin Manwu, but still did not collect the rare metals.

Jiang Xingchen had no choice but to put this problem aside first. There were other things in the territory, so he couldn't just focus on this. It was the end of December soon, and he had to ensure that the winter arrest went smoothly.

But at this time, good news came from Xianning. The people who went out brought back a stone that was more fire-resistant than the materials in the past.

Jiang Xingchen immediately ran to the research institute again and saw a white stone, slightly gray. There was a pile of powder next to this stone, which looked like flour.

"Xingchen, look, this is what I'm talking about, next to it is crushed powder! I've burned the kiln to a bright red flame, and these stones are fine!" Xian Ning said excitedly.

Before Jiang Xingchen could speak, Xianning continued, "And I thought of a method to build a kiln. We combine quartz sand, soda ash, and feldspar, plus large bluestone powder, calcined into bricks, and use it to build a kiln, because the material itself is the raw material for producing glass, so..."

While Xianning was talking here, Jiang Xingchen's eyes were always staring at the pile of white powder, as if he hadn't heard Xianning's words.

"Xingchen, Xingchen, have you listened to me?" Xianning noticed Jiang Xingchen's abnormality and patted him gently.

But even so, Jiang Xingchen still did not respond. Instead, he reached out and pinched a pinch of powder, twisted it gently, and murmured: "This seems... porcelain clay!"

"Uh!" Xian Ning was stunned and asked, "Xingchen, what did you say?"

Jiang Xingchen suddenly raised his head and said with a smile: "Xian Ning, this thing may be porcelain clay. We will do an experiment later. If it is true, not only will our problem be solved, but this is also a way to make a fortune... By the way, where did this thing be found?"

Xian Ning stared at the excited Jiang Xingchen blankly and pointed to the side: "You ask him!" (To be continued, please search for Astronomy, novels are better, updated and faster!
