The important discovery of the research institute made Jiang Xingchen have no time to care about it. Xiao Fengqiu failed to act cute and pretend to be pitiful for the last time, so he could only ask for help with the old man, Tang Chuxue and the kitten girl.

But the old man seemed not to see Little Pomel's request for help. He lowered his head and pondered for a moment, shouted Little Hundan, etc., and ran after Jiang Xingchen.

Tang Chuxue also didn't look at the little pomrose, but with his hands on his back, his feet were like flowing water, and he quickly went down the mountain and left.

This is even more true for the kitten woman. She is busy commanding millions of bees to go back and has no time to deal with the small pomrose. Even crabs and leeks ignore this. This is in jail, and they dare not plead for mercy. If they anger the boss and lock themselves up for two days, they will be in trouble.

But in a moment, the top of the back mountain turned empty, leaving only small pompoons and cats with obvious malicious smiles.

"A bunch of cold-blooded, no loyalty..." Xiao Fengqiong was so depressed that she cursed in her heart, but in the end it was useless and was taken into the cage by the cat star...

Jiang Xingchen was stopped by the old man after walking not long ago, and stopped and turned around 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 when you go to the research institute!" the old man said loudly.

Jiang Xingchen frowned and nodded: "Then what do you think?" When he thought, the old man came to ask for wine again. Since Drunk Fist, the old man came to ask for wine almost every day. However, the brewed "Green Wine" still needs to be purchased by territory and super users, and it is not surplus. The second batch of sorghum transported is still fermenting, so Jiang Xingchen did not agree.

However, when the old man opened his mouth, Jiang Xingchen realized that it was not what he imagined.

"I remember a description of Ye Owl in ancient books, saying that this monster is very revengeful and mostly exists in the form of a family. I am worried that the night owl that ran away today will probably not stop!" The old man said solemnly.

Jiang Xingchen became solemn when he heard this. If what is said in ancient books is true, it would be really troublesome. Even if there is only the night owl in the Ye Owl family that is at level 24, the others are night owls below level 20. It is not easy for Xingchen to deal with threats from high altitudes when pink is not around. After all, there is only one high-end force in the air!

It is okay to mobilize big bees or beetles to come. The key is that you don’t know when the night owl will come. Only a thousand days to catch thieves, so how can you defend against thieves? Bees have their own jobs. The same goes for beetles.

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

"Yeah! I understand!" Jiang Xingchen nodded and began to think about countermeasures.

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

Jiang Xingchen looked at the old man and suddenly smiled: "So I guessed right. The ultimate goal of you old guy is to make new white wine..."

After a moment of pause, Jiang Xingchen continued, "Old thing. I said why are you so addicted to pretending to be so addicted to it? If you say you are used for cultivation, I will give it to you even if you are nervous! But the purpose of your request for liquor is to find Lao Marquis and Mr. Huang Shi and others to show off. Do you think I can give it to you... For your cultivation, I racked my brains to think of the method of using the drunken fist to guide you, so you're fine..."

"Who said I wanted wine to show off?" Before Jiang Xingchen finished speaking, the old man immediately interrupted. He shouted righteously: "I want white wine to practice! Give it to me quickly, I will start to retreat immediately. Now I feel like I'm about to break through!"

Jiang Xingchen's mouth twitched when he heard it, and he wanted to jump over and kick the old guy. His ability to tolerate idiots was reduced. Can you say more falsely? If you practice Drunk Fist, you went to ask Wan Rou and his second brother for help, but you said you went to retreat... After drinking in seclusion, do you still practice nonsense? The most annoying thing is that the old guy actually said arrogantly that he had a feeling of breakthrough. You are practicing the body now, not vitality, so where does the feeling of breakthrough come from!

"There is no white wine now. Let's talk about it when you brew the second batch of white wine!" Jiang Xingchen replied coldly, turned around and left, leaving the old man in place.

The old man opened his mouth and stared at Jiang Xingchen walking away, suddenly shouting: "Little Hundan, without you, I'll tell you the news, you'll run away after eating it, this is a bridge that will be destroyed after crossing the river..."

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

When he arrived at the research institute, a young man in his twenties had been waiting at the door. He was one of the first children to come to the territory, named Du Peng, who was very respected by Xianning.

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

At first glance, Du Peng strode forward to meet Jiang Xingchen: "Sir, you are here!"

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

"When I was calcining the ore with charcoal, I found a silver-white liquid, which was very similar to the mercury recorded by the dean! I will send someone to come to you right away!" Du Peng replied.

"Mercury?" Jiang Xingchen was a little surprised. Did he discover cinnabar? No, cinnabar is mercury sulfide. If mercury is obtained directly from cinnabar, just heat it directly, and there is no need to restore charcoal at all!

Want to get the answer as soon as possible, Jiang Xingchen asked Du Peng to lead the way quickly, and the two of them stepped up their pace and came to the laboratory quickly.

There are private soldiers guarding the laboratory, and even if the level in the research institute is not enough, it is mainly to guard against those students who come to study from the Imperial Academy.

The place for calcination is not in the laboratory, but in a courtyard behind the laboratory. Since there are many types of ores, I don’t know what their characteristics are. What if they are toxic? Just like phosphate ores, refining white phosphorus is toxic.

Therefore, Jiang Xingchen placed the experiment location behind the laboratory and required that when performing calcination experiments, he had to bring a mask with toner added.

The two passed through the laboratory and entered the backyard. The calcination in the crucible continued. Jiang Xingchen put on a mask and came to him. Sure enough, he saw a ball of bright silver liquid the size of grape beads in the crucible.

"It's really mercury?" Jiang Xingchen had just thought, and his eyes condensed. He found that the gray-black ore fragments were burned by charcoal.

"Huh?" Jiang Xingchen frowned again. Shouldn't the cinnabar be red? Why is the ore gray-black?

Du Peng looked at Jiang Xingchen nervously from the side and asked in a low voice: "Sir, how about it? Is it mercury?"

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

"Okay!" Du Jiang nodded, took the lid, covered the crucible, and isolated the air.

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

Du Peng stopped moving and sat in a chair with Jiang Xingchen and waited quietly.

Jiang Xingchen didn't say anything, and Du Peng didn't dare to speak. The lab was so quiet that there was no sound, which made Du Peng feel a little depressed.

After a full month (month), Jiang Xingchen suddenly stood up, reached out and touched the surface of the crucible, and then opened the lid of the crucible with his hands.

"Not mercury!" Jiang Xingchen laughed at the moment when he saw the situation in the crucible. The bright silver liquid bead just now had condensed into a piece of silver-white metal.

The reason why he laughed was because the current situation confirmed his guess. Although this is not mercury, it is much more effective than mercury for the current star collar. If the crucible is really mercury, it is indeed an important discovery. But now this piece of metal is even more important than the major discovery, 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 found was mercury, but unexpectedly it was another metal.

But he had no regrets. When he was experimenting, the temperature of the crucible was only more than 200 degrees. It melted at more than 200 degrees, and then condensed into solid at room temperature. This is also a new metal that has never been discovered before.

Jiang Xingchen used tweezers to clip out the silver metal from the crucible, and said with a smile: "This should be tin... Haha, you can come whatever you lack!"

Tin was discovered by the world in its previous life, and was called one of the hardware in ancient times of Jiang Xingchen's motherland. However, it has never been discovered in this world.

At first, he thought that there might not be any metal element like tin in this world, just like saltpeter and metal copper cannot be found. But he didn't expect to find it so suddenly.

Now the ground construction of the new city is being accelerated, and the demand for flat glass has been put on the agenda. He and Xianning have been thinking about how to make flat glass. Now that the sudden appearance of tin has solved one of his major problems, float glass can finally be made.

In fact, since he discovered the color of the ore just now, he suspected that it was tin ore, because liquid tin is very similar to mercury. If Du Peng hadn't been next to him, he would have wanted to go over and use the temperature-controlled pressure array immediately.

"Xin?" Du Peng shook his head. He learned Mercury from Xianning's notes, but Xi had never heard of it.

Jiang Xingchen laughed, patted Du Peng on the shoulder and said, "You have made great contributions this time. Your dean knows that it is still not clear. The problem that has been bothering her is about to be solved!"

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

Jiang Xingchen didn't say much, so he found a knife and cut the metal off in two slight strokes.

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

"By the way! Who found this ore? Come back quickly!" Jiang Xingchen suddenly remembered this important question. (To be continued...)
