Global Trial

A very mechanized and undistracted voice said: "Trial officer 5761 has felt your desire and call for the dungeon, and welcomes you to enter the lab dungeon of the main trial level."

A "little man" full of metal and mechanical sense stood in front of Xia Mingdong, the height was only about his waist. The little man was made of silver-white metal, with a human-like torso and limbs but no facial features. Two small red dots flashed at the position of the eyes.

Xia Mingdong: "You are... the trial officer? Can you see us?"

"Please don't doubt the tester's eyes, I can see everything." 5761 said rigidly, "And I heard 7891 mention you."

Xia Mingdong laughed, "That must not be a good word."

"Of course." A little emotion could be heard in the mechanized voice of 5761, "You are so hateful, you dare to beat the trial officer, you three..."

5761 paused, "No, aren't there three of you, why did you become four?"

Xia Mingdong: "Oh, our team has expanded."

5761: "There is one more hateful tester."

"Why do you have such a big opinion on us?" Xia Mingdong asked curiously, "What is the relationship between 7891 and you? What have you guys talked about?"

5761 moved his body, "Of course we are..."

For some reason, 5761 did not continue.

Xia Mingdong realized something, "You guys know each other and often communicate together. It seems that you have a good relationship. After all, you still hate the tester who once bullied him? If you use the relationship between modern people on the earth to describe you, you two are more like... …colleague?"

5761:"……"

This damned tester, he only said one sentence, how could he guess so much.

What's even more exaggerated is that Xia Mingdong is still guessing.

"You are all in charge of a series of dungeons of the Chief Trial Officer, so can you speculate that you are all subordinates of the Chief Trial Officer? Trial Officers should have ranks, and your different numbers should also mean different levels, right? ?”

5761 stood there quietly, with a sense of vicissitudes and helplessness on his face without facial features.

Why... guessed it again, does this damned tester have any special talents that even they don't know about?

"However, I guess you and 7891 should be on the same level." Xia Mingdong said, "Since you have heard about us from 7891, why not just tell me the rules and tasks, you come and I go for a while and then talk about how troublesome and delayed the dungeon tasks are." Everyone time."

"No..." 5761 was struggling almost desperately, "I think it's necessary, you can do whatever you want, it's very quiet and peaceful here, don't worry about the punishment for not passing the copy, you can stay here with peace of mind..."

"It's just that there is no food and water. If you don't leave here, you can only sit and wait for death, right?" Xia Mingdong shook his head and sighed, "Why don't you have a long memory? This trick is useless to me."

"...Necessary procedures, thank you for your cooperation."

Ren Sheng watched silently from the side, and for the first time felt that 5761 looked weak, pitiful and helpless.

"Then please cooperate and explain the clear rules and missions of this dungeon." Xia Mingdong continued, "But you can roughly guess a part of it. The clear rules of the dungeon should not destroy the laboratory and the like, and the missions should also follow related to the laboratory."

5761: "I think you can break through the level by yourself."

"No, the process still has to go." Xia Mingdong said, "You have to tell me what the mission is and the clues."

A reminder came from the trial system——

Instance: Chief Trial Officer's Laboratory (in progress)

Dungeon Requirement: Find the research results belonging to the Chief Trial Officer in the laboratory

progress: none

Reward: unknown

Xia Mingdong: "I have received the mission request, what about the clues, and the rules that cannot be violated? Don't play word games with me, believe me, you will never be able to play mine."

5761 stared at Xia Mingdong with those little red dots instead of eyes, and the entire mechanical body exuded silence and rejection.

Xia Mingdong was not in a hurry, he casually looked in the laboratory.

The rules of the chief trial officer's series of dungeons seem to be in the same line, and the clear rules are basically the same.

The previous rule was that the candy house cannot be destroyed, but the word "destruction" is very connotative and full of the charm of words. Only moving the candies in the candy house aimlessly is destruction, and tidying up is not destruction.

He thinks that this level cannot destroy the laboratory, but it does not mean that he cannot move or use the instruments in the laboratory.

The laboratory is closed on all sides, without a single window or door, with the most traditional incandescent lamp overhead, surrounded by the latest optical and electromagnetic related instruments, and a lot of materials, but these instruments and materials have no traces of use .

The laboratory is not big, so I quickly looked around, and 5761 was still standing on the floor in the middle of the laboratory in a daze.

Xia Mingdong shook his hand in front of 5761, but 5761's red eyes did not respond.

Xia Mingdong was thoughtful.

After a few minutes, he coughed lightly and asked 5761, "Have you figured it out?"

5761:"……"

"The chief trial officer likes to treasure his inventions and creations." 5761 said, "Please conduct scientific research in the laboratory."

Instance: Chief Trial Officer's Laboratory (in progress)

Dungeon Requirement: Find the research results belonging to the Chief Trial Officer in the laboratory

Progress: Please carry out relevant scientific research

Reward: unknown

A few other people had obviously seen the related missions. Ren Sheng didn't understand human high-tech, so he was blinded by these missions. Ning Ge looked indifferent, not knowing if he understood. Only Cen Heng came to Xia Mingdong's side and said: "Why do these look so high-tech instruments in school laboratories, what do you want us to do?"

"Carry out relevant scientific research." Xia Mingdong said casually, "When will you learn to examine questions?"

"What are you researching?" Cen Heng pointed to the things in the laboratory, "Those things are unknown to me, are you sure we can research something?"

"So we are looking for reference materials, which are references." Xia Mingdong can probably recognize some instruments, but he is not sure. He has not studied optics, electromagnetism and other subjects in depth, but he can tell what those instruments are for. Used, but not very proficient in the principle.

There are generally relevant literature materials as references in the laboratory. If you can find reference materials, it should be able to speed up their copy process by a big step.

Xia Mingdong gave a clear direction, and the other three followed to find it, but the four turned the laboratory upside down but found nothing.

Cen Heng scratched his head, "Fourth, could it be that you are thinking wrong, maybe there is no reference material in it, the Chief Trial Officer should not be able to leave us a copy clue thoughtfully."

"But every dungeon must have clues..." Xia Mingdong whispered, "Research in the dungeon..."

The laboratory is not big, and you can see all of it at a glance. It takes a lot of skill to hide things in such a place. According to previous experience, this place for hiding things will definitely be slanted, and it will not be placed so conspicuously that people Places that people can see at once will not be placed in a remote corner, and they need to rummage through boxes and cabinets or even pry open instruments to find them.

Must be an amazing location.

And this position is related to doing research.

According to the currently known clues and tasks of the dungeon, research is needed, and this place should be found using the results of the research.

So what is the use of their current optical and electromagnetic instruments and various materials.

Xia Mingdong slowly walked back and forth among various instruments and materials.

Cen Heng looked dizzy, and asked: "Fourth, did you see anything?"

Ren Sheng silently reduced his sense of existence at such a time, and he, an illiterate, should not be able to help.

Ning Ge will always be by Xia Mingdong's side no matter whether he can help or not.

Xia Mingdong slowly picked up a strange material, it was a round block of gray-black metal, with a texture between crystal and frosted, with a few letters engraved on the back: metamaterial

He froze for a moment, it was a super material.

Metamaterials are a new concept that only emerged in this century. They usually refer to materials composed of artificially synthesized structures. These materials usually have extraordinary physical properties that natural materials do not have.

Here comes the metamaterial...

And it is very likely that it is a metamaterial that cannot be synthesized by current earth science and technology, and may have special uses.

He saw the instrument next to the block again, and it read: DARPA

If he guessed correctly, the full name of DARPA should be: Defense-Advanced-Research-Projects-Agency

negative refraction material.

optics, electromagnetism...

Xia Mingdong seemed to realize something, and suddenly looked back at 5761.

5761 has no real facial features, only a pair of eyes like infrared emitting points.

This is the first trial officer he has encountered without five senses.

What exactly does this mean.

Things are complicated, as if shrouded in a cloud of fog, he can see many lines of things, but he can't connect these lines together to form a perfect closed circle.

The clues are too messy, and he can't judge the core content and essence of the dungeon for the time being.

He put down the materials in his hand, stood there and meditated for a moment, and walked over to 5761.

As we all know, he didn't have the slightest reverence for the trial officer, and he simply sat on the ground next to 5761 and looked at 5761's eyes curiously.

Cen Heng: "... Fourth brother, what are you doing?"

"If you are undecided, find the trial officer."

"...that's okay too?"

"There's nothing wrong with it, chatting will never violate the rules." Xia Mingdong waved his hands casually.

5761 seemed to be aware of the gaze of others, and turned the silver-white mechanical neck uncomfortably, "This tester, please don't get too close to the tester."

"Don't you know who I am?" Xia Mingdong asked curiously with one hand on his chin: "Can you tell us apart, and do you know who your colleague 7891 hates the most?"

Ren Sheng: "..."

I actually went to chat with the trial officer, but will the trial officer give the trialer any clues?

They seem to be hoping that the tester will not be able to pass.

The author has something to say:

I really went to CNKI to read the paper, do you believe it QAQ

Please bear with me if there are places that are not logical or scientific, I will try my best orz...
