The important discovery of the research institute made Jiang Xingchen have no time to take care of it, and the last time the little pompom was sold cutely and pretending to be pitiful, he could only ask the old man for help, Tang Chuxue and the little cat girl.

But the old man didn't seem to see the little pom-pom's request for help, lowered his head and pondered for a moment, shouted a little soul and so on, and ran after Jiang Xingchen.

Tang Chuxue also didn't look at the little pompom, turned her hands behind her back, and her feet were like clouds and water, and she quickly went down the mountain and left.

This is especially true of Catwoman, who is busy directing millions of bees to go back, and has no time to take care of the little pompoms. Even crabs and leeks turn a blind eye to this. This is confinement, and they don't dare to plead, if they anger the boss and lock themselves up for two more days, they will be unlucky.

In a moment, the top of the mountain became empty, and only small pompoms and cats with obvious malicious smiles remained.

"A group of cold-blooded, unrighteous ......" The little pom-pom was so depressed that he scolded in his heart, but in the end, it was useless, and he was obediently taken to the cage by the cats......

Jiang Xingchen walked not far before the old man shouted, stopped and turned his head and asked, "Old guy, let's talk about it later, I'm in a hurry to go to the research institute!"

"This matter is more urgent than you going to the research institute!" said the old man.

Jiang Xingchen frowned and nodded: "Then what do you say, what is the matter?" In his mind, the old man came to ask for wine again. Since the drunken boxing, the old man has come to ask for wine almost every day. However, the sorghum wine brewed is not surplus to be purchased by the territory and super users. The second batch of sorghum was still fermenting, so Jiang Xingchen did not agree.

However, wait for the old man to speak. Jiang Xingchen realized that it was not what he imagined.

"I remember a description of the night owl in an ancient book, saying that this monster is very vindictive. And most of them exist in the form of families. I'm worried that this night owl that ran away today won't stop there!" the old man said solemnly.

Jiang Xingchen also became solemn when he heard this. If what is said in the ancient books is true, then it is really troublesome. Even if only that night owl in a night owl family is level twenty-four, and the others are all night owls below level twenty, it is not easy for the star leader to deal with the threat from high altitudes in Pink's absence, after all, there is only one high-end force in the air!

It is possible to mobilize big bees or beetles, but the key is that we don't know when the night owls will come, and we can only catch thieves for a thousand days, so how can we prevent thieves for a thousand days? Bees have their own jobs. The same goes for beetles.

"Boy, you'd better come up with a solution sooner!" said the old man.

"Hmm! got it!" Jiang Xingchen nodded, and his mind began to think about countermeasures.

At this time, the old man spoke again: "Boy, you should think slowly about countermeasures first! What, I provide you with such important news, should you give me some rewards!"

Jiang Xingchen looked at the old man and suddenly smiled: "It turns out that I guessed correctly." The ultimate goal of your old thing is still for the new liquor......"

After a slight pause, Jiang Xingchen continued: "Old thing. I said, why are you so addicted to pretending? If you say that it is used for cultivation, even if you are nervous about the liquor, I will give it to you! But the purpose of asking for liquor is to find the old marquis and Mr. Huang Shi and them, do you think I can give it to you...... For your cultivation. I've racked my brains to think of a way to guide you with drunken fists, you're ......"

"Who said I wanted wine to pretend to be forced?" Before Jiang Xingchen could finish speaking, the old man immediately interrupted. He said loudly and righteously: "I want baijiu just to practice! Hurry up and give it to me, and I will start the retreat immediately." Now I feel like I'm about to break through!"

The corners of Jiang Xingchen's mouth twitched when he heard this, and he couldn't wait to jump over and give this old guy a kick. His ability to tolerate fools has been reduced. Can you be more fake when you talk nonsense? Cultivating drunken boxing, you didn't say that you would go to Wanrou and the second brother for help, but you said that you would go to retreat...... Drinking in retreat, you still practice a fart. The most annoying thing is that the old guy is ashamed to say that he has a feeling of breakthrough, what you are practicing now is the body, not vitality, where does the feeling of breaking through come from!

"There is no liquor now, let's wait for the second batch of liquor to be brewed!" Jiang Xingchen replied coldly, turned around and left, leaving the old man still in place.

The old man opened his mouth, watched Jiang Xingchen walk away in a daze, and suddenly provoked and yelled: "Little Soul Dan, there is no such thing as you, I will tell you the news, you eat and wipe clean and run, this is crossing the river and demolishing the bridge......"

Jiang Xingchen turned a deaf ear to the old man's shouts and hurried to the research institute.

When he arrived at the research institute, a young man under twenty years old was already waiting at the door, it was one of the first children to come to the territory, named Du Peng, who was very valued by Xian Ning.

This time, the Xianning Belt R&D team left the research institute and appointed him to take over the research and analysis of various ores.

Seeing Jiang Xingchen at a glance, Du Peng strode up to greet him: "Sir, you are here!"

"Du Peng, what is the important discovery?" Jiang Xingchen immediately asked.

"When I was calcining ore with charcoal, I found a silvery-white liquid, very similar to the mercury in the dean's record!

"Mercury?" Jiang Xingchen was a little stunned, could it be that he had discovered Dansha! No, Dansha is mercury sulfide, if you get mercury directly from Dansha, you can just heat it directly, and you don't need charcoal to reduce it at all!

Thinking of the answer in his heart, Jiang Xingchen asked Du Peng to lead the way quickly, and the two of them stepped up their steps and soon came to the real room.

There are private guards in the real room, and you can't enter the academy if you don't have enough rank, mainly to guard against those students who come from the Imperial Academy to study.

The place of calcination is not in the real yàn room, but in a courtyard behind the real yàn room. Since there are many types of ores, I don't know what the characteristics are, but if they are poisonous. Just like phosphate rock, refining white phosphorus is toxic.

Therefore, Jiang Xingchen placed the location of the real yàn at the back of the real yàn room, and required that when calcining the real yàn, he must wear a mask with toner.

The two of them passed through the real room, and when they entered the backyard, the calcination in the crucible was still continuing, Jiang Xingchen put on a mask and approached him, and sure enough, he saw a bright silver liquid the size of grape beads in the crucible.

"Is it really mercury?" Jiang Xingchen just came up with this thought, his eyes froze again, and he found that what was being calcined by charcoal was gray-black ore fragments.

"Huh?" Jiang Xingchen frowned again, shouldn't the dansha be red, why is the ore gray-black?

Du Peng looked at Jiang Xingchen nervously beside him, and asked in a low voice, "Sir, how is it?"

Jiang Xingchen shook his head and said, "It's impossible to judge yet! In this way, let's end the calcination first and lower the temperature!"

"Okay!" Du Jiang nodded, brought the lid, and covered the crucible to isolate the air.

Not long after, the temperature of the crucible began to drop, and Du Peng was just about to lift the lid, but Jiang Xingchen blocked him: "Wait a little longer!"

Du Peng stopped his movements and sat on the chair with Jiang Xingchen and waited quietly.

Jiang Xingchen didn't speak, Du Peng didn't dare to speak, and there was so much silence in the room that there was no sound, which made Du Peng feel a little depressed.

After a full month, Jiang Xingchen suddenly got up, reached out and touched the surface of the crucible, and then directly opened the lid of the crucible with his hand.

"It's not mercury!" Jiang Xingchen laughed the moment he saw the situation inside the crucible. The bright silver bead just now had condensed into a piece of silvery-white metal.

And he laughed because the current situation confirmed his suspicions. Although this is not mercury, it has a much greater effect on the current star collar than mercury. If the inside of the crucible is really mercury, it is indeed an important discovery. But now this piece of metal is heavier than the heavy dà, which can definitely be called a huge surprise for Jiang Xingchen!

"What kind of metal is this?" Du Peng asked subconsciously. He always thought that what he had found was mercury, but he didn't expect it to be another metal.

However, he has no regrets, when he was real, the temperature of the crucible was only more than 200 degrees. It melts at more than 200 degrees Celsius, and condenses into a solid at room temperature, which is also a new metal that has not been discovered before.

Jiang Xingchen used tweezers to clip this piece of silver metal out of the crucible, and said with a smile: "This should be tin...... Hehe, what is really lacking will come!"

Tin was discovered by the world long ago in the previous life, and it was known as one of the hardware in the ancient times of Jiang Xingchen's motherland. But in this world, it has not been discovered.

At first, he thought that there might be no metal element such as tin in this world, just as saltpeter and copper metal could not be found. I didn't expect it to be discovered so suddenly.

Now the above-ground construction of the new city is accelerating, and the demand for flat glass has been put on the agenda. He and Xian Ning had been wondering how to make flat glass. Now the sudden appearance of tin has simply solved one of his big problems, and float glass can finally be done.

In fact, from the color he found out about the ore just now, he suspected that it was tin ore, because liquid tin is very similar to mercury. If it weren't for Du Peng being next to him, he wouldn't have been able to go over immediately and use the temperature control pressure array.

"Tin?" Du Peng shook his head, he had learned about the mercury from Xian Ning's notes, but Xi had never heard of it.

Jiang Xingchen laughed, patted Du Peng's shoulder and said, "You have made a great contribution this time, your dean knows how to be happy, and the problem that has been bothering her is about to be solved!"

Du Peng was confused and confused when he heard it, and he only knew how to nod his head.

Jiang Xingchen didn't say much, found a knife, and cut off a piece of metal with two clicks.

"It's so soft, it should be tin!" Jiang Xingchen nodded, he originally wanted to use the temperature control pressure array to lower the temperature and continue the test, but Du Peng was still here, so he could only give up. However, it has now been basically confirmed that this is the metal tin.

"That's right! Who found this piece of ore, hurry up and gather it back!" Jiang Xingchen suddenly remembered this important question. (To be continued......)
