Global Trial

"What is it for?" Cen Heng asked, and added: "Can you explain it to us in Yangjian dialect, which is easy to understand and understood by ordinary people?"

Xia Mingdong: "...Since when did I talk about the underworld?"

"Basically every time." Cen Heng complained, but his voice was very low, obviously afraid of Ning Ge.

Xia Mingdong rolled his eyes, "Then don't listen to the underworld."

Cen Heng: "...No, I still have to listen, and I can't give up the treatment."

"Then I'll tell you."

Xia Mingdong typed in the trial system: If I remember correctly, soft materials are used for thermodynamic stealth

Cen Heng:? ? ?

Cen Heng: Why is thermodynamic stealth involved?

Xia Mingdong: Of course it is to give the trial officer 5761 cards

Cen Heng: What do you mean?

Xia Mingdong: Didn't you find something very obvious?

Cen Heng: What?

Xia Mingdong: I'm so sorry that your observation skills are so poor

Cen Heng: ...

Ren Sheng: ...

Xia Mingdong: 5761 has not moved since we entered this instance

When he said this, Cen Heng and Ren Cheng suddenly realized that it was true.

5761 has been standing in the middle of the lab since the beginning, has been standing in the middle, never moved.

Xia Mingdong: Whether it is a trial level or a dungeon, there is no rule that the trial officer cannot move, so I speculate that 5761 has been standing still, and it should be hiding or protecting something extremely important

Xia Mingdong: The only thing worth protecting in the whole dungeon is the invention and creation of the Chief Trial Officer

Cen Heng: What do you mean, so that the inventions and creations that we cannot see are around 5761?

Xia Mingdong: I guess so, but it needs to be verified

Cen Heng: How to verify it?

Xia Mingdong: I think splashing water should be useful

Cen Heng: ...splashing water on the trial officer 5761?

Xia Mingdong: Otherwise?

Cen Heng scratched his head, as if there was really no better way.

Ren Sheng couldn't help typing another line: So now, what's going on with that thermodynamic invisibility?

Xia Mingdong: Thermodynamic cloaking requires the use of soft materials. Ideally, soft materials can be completely adsorbed on another solid. There is no air between the two objects, so that the contact thermal resistance is zero. If we cover the whole body with soft materials, theoretically we can The thermal contact resistance among the three, soft material and air is zero, and the frequencies and wavelengths emitted by the three of us are exactly the same, so 5761 has no way to capture our traces through infrared imaging, and we can approach 5761 silently , looking for traces of inventions

Cen Heng: Is it so metaphysical?How does it feel like we have become air?

Xia Mingdong: Actually, it's not impossible to understand...

Cen Heng: ...

Cen Heng: So how to produce soft materials?Also, are you sure you don’t want to give us some cool negative refractive index materials? After listening to it for a long time, I feel that we only need soft materials to steal things from 5761 quietly by achieving thermodynamic invisibility in front of 5761. What is invisibility for?

Xia Mingdong: No matter what the purpose is, shouldn't we scoop up the dungeon's wool?Something like a perfect invisibility cloak can't be used in this dungeon, so can it be used in other dungeons?

Cen Heng: It makes sense, wool, squeeze!

Ren Sheng: ... So, how should it be produced?

Xia Mingdong: Just make whatever you want, follow the instruction manual

Cen Heng: ...?

Xia Mingdong stopped explaining, casually picked up the materials on the table and stood in front of the machine labeled SF.

Cen Heng swallowed, and asked vainly, "Fourth, what do you want to do?"

"Follow the instructions." Xia Mingdong had an innocent face, as if he didn't seem to have that kind of bold attempt at all, "The instructions say ingredients, start, just throw the ingredients in, and then start."

Cen Heng: "...don't need to distinguish which raw material belongs to which instrument?"

Xia Mingdong pointed to the various metamaterials on the table: "You do what you want."

There are various materials on the table, there are stones like silicon dioxide, crystals like cristobalite, and black balls like coal. After a few glances, Cen Heng hesitated, and said directly: "I can't, it's you Come."

Xia Mingdong: "So let's just let it go, we can't tell the difference anyway, if something goes wrong, we can only blame our bad luck."

"Then you come." Cen Heng immediately handed over the job, "You know I have a dark face, I have never left the country to enter Europe, and I have never won a five-yuan lottery since I was a child. I don't have a chance, so you do what you want."

Xia Mingdong didn't care, he felt that if something happened, the four of them who were in the same laboratory would definitely not be able to escape, so it didn't matter who came.

He didn't pick and choose, just randomly picked up a stone-like metamaterial and wanted to throw it into the soft material instrument.

Ning Ge grabbed Xia Mingdong's hand and whispered, "I'll do it."

He took out the material from Xia Mingdong's hand, and rubbed his fingers against Xia Mingdong's palm, carrying his body temperature slightly higher than that of ordinary people, Xia Mingdong felt scalded.

Ning Ge stood in front of the instrument, his eyelids drooped, his expression was cold and indifferent, and he held the material with his slender fingers, "Stay away from me."

Xia Mingdong: "...Are you talking about me?"

"Yes." Ning Ge said: "Hide behind Cen Heng and the others, don't get hurt."

Cen Heng: "..."

He doesn't want to get hurt either.

Xia Mingdong smiled, "It's actually nothing."

Ning Ge pursed his lips, turned his head slightly, and looked at Xia Mingdong persistently, his golden black eyes were full of seriousness and determination.

Looking into those eyes, Xia Mingdong gradually softened his heart, and backed away obediently, "Okay, I'll stand behind Cen Heng, I believe that Cen Heng's huge and fat body will definitely block me."

Cen Heng was speechless: "Please, I'm only slightly fat, I'm not so big and fat, I'm just not as thin as you are."

Xia Mingdong: "Cooperate, you are big and fat now."

Cen Heng: "...All right."

Ren Sheng looked at it, and also wanted to squeeze behind Cen Heng silently, but due to his relatively large size, it was impossible to be blocked, so he could only stand obediently by the side.

Ning Ge directly threw many unknown metamaterials into the instrument, and then pressed the green start button.

5761 saw the figure standing beside the instrument without even saying a word. He had a feeling that the group of testers had already found the key to the dungeon. It was useless for him to talk more, as if resistance was futile.

No, he still had to resist.

The green start button was pressed, the entire instrument lit up, and there was an obvious sound of electric current. Strange and weird words flashed on the instrument screen one after another, and the control panel in front of the instrument lit up with several colors of light.

Ninge took a few steps back, stood in front of them, and looked at the instrument calmly.

After about 1 minute, the previously lit light on the instrument gradually went out, and the originally closed metal surface below directly bounced off, and a metal disc popped out.

As the disc pops out, the instrument comes to a complete stop.

Ning Ge stood on the spot and waited for a while, but he didn't see that the instrument continued to start, so he stepped forward and leaned over to look at the things in the disc.

Xia Mingdong poked his head out from behind Cen Heng, and walked over when he saw nothing.

Inside the metal disc is a soft material between liquid and solid, like transparent jelly, which feels like a gel.

Xia Mingdong wanted to reach out and touch it.

Ning Ge grabbed his hand, and reached out to try to touch the soft material in the metal disc.

"How is it?" Xia Mingdong was caught by Ning Ge and couldn't move his hand, "Is there something wrong?"

"No." Ning Ge said, "It's a bit sticky."

Xia Mingdong: "Then can you let me go now?"

Ning Ge let go of Xia Mingdong as usual, as if nothing had happened.

Xia Mingdong also tried to touch the "jelly" in the metal disc, just like what Ning Ge said, it felt sticky.

But when you really want to leave the soft material, nothing sticks to your hands, and the characteristics are very strange.

It just feels disgusting when you touch it, but if you really don't touch it, it won't leave marks on your body.

Cen Heng stood behind and looked at Xia Mingdong and Ning Ge's heads touching each other, and lowered his voice to ask Ren Cheng: "Do you think we can pass now?"

Ren Sheng: "What are you in a hurry to do, can you be useful?"

Cen Heng: "...We can still be friends without revealing."

Ren Sheng: "I don't want to be friends with you."

Cen Heng: ...

This goddamn ancient animal husbandry.

Xia Mingdong stood up, ignoring the contents of the tray, "Let's try another instrument."

Ning Ge directly followed the method just now, crammed the materials on the table into the instrument, and pressed the start button.

They couldn't see the material that popped out of the metal tray this time.

When Ning Ge stretched out his fingers to touch, he didn't know what happened. One of his fingers seemed to be entangled by invisible materials, and it looked like it was broken, leaving only one part, which was quite terrifying and mysterious.

"Damn it?" Cen Heng couldn't bear it this time, and went directly to pick up the optical cloaking material and wrapped it around his hands.

To the naked eye, his wrist seemed to be cut off in the middle. He could feel his hand, but he couldn't see it with the naked eye.

He rubbed his glasses and exclaimed in surprise, "It's amazing, my God, there is such a black technology, I must get more."

Xia Mingdong glanced at the top of the instrument, "I think this matter may not go as you wish."

"why?"

"Because the instrument seems to have completely stopped working."

The green button on the top of the instrument split in two at some point and could no longer be activated.

Xia Mingdong concluded: "It must be because we don't want to be plucked by us and changed the rules temporarily."

5761, who had been silent for a long time, couldn't help it anymore, "No, each instrument can only be used once."

"Oh." Xia Mingdong criticized, "Why are you so stingy? You can only use it once to fight. As the chief trial officer, you should be more generous and don't be so petty like other trial officers."

5761:"……"

This group of testers is really annoying.

He had never met such a nasty tester.

The author has something to say:

5761: Already bald by you!
