Global Trial

Vector: a geometric concept with both magnitude and direction

Gravity is also a type of vector.

The largest vector on the ground is gravity. Does detecting the ground vector mean detecting the gravity of the ground?

Why, it turns out that the Floating Void City also tried to change the gravity of the ground.

These tasks are under the instruction of who, who is responsible for the scientific research progress and task assignment of the crystal people.

Xia Mingdong didn't see any blank tasks on the task board, which proved that he had already received all the tasks. He tried to ask the crystal people around him vaguely: "When will there be new tasks?"

"I don't know." The male crystal man next to him replied indifferently: "The next task must be carried out according to the detected data results."

Xia Mingdong: "Then did any major incident happen recently? I see that there are so many people around... The task was completed so quickly."

The male crystal man narrowed his eyes and looked at him, Xia Mingdong noticed the number plate on his chest: five

Crystal person No. [-] looked at Xia Mingdong suspiciously, "How could you not even know about this kind of thing? Tomorrow is your birthday."

"Sorry, I just came here recently." Xia Mingdong gave a random reason, "What is a birthday?"

"Birthday is the rebirth of the floating city." No. [-] calmly stated: "On the birthday, we will create new light and suspension, and completely discard the garbage on the ground before. It is a birthday that belongs only to the floating world. "

Xia Mingdong: "..."

Suddenly there is a feeling of coming from a science fiction world to a cult organization.

"Conscientiously complete the inspection task." No. [-] explained, "We must ensure that tomorrow's birthday is safe."

Xia Mingdong: "...Okay."

A new task appeared on the task panel——

Detects changes in vector due to changes in temperature

Xia Mingdong immediately took the task, tried to input the number at random, and succeeded.

Xia Mingdong: "..."

Crystal Man is really confident and inflated.

After receiving the task, he pretended to find an instrument and was ready to start working.

Cen Heng and the others followed not far away, while Ning Ge followed Xia Mingdong directly.

In this level, they are not in the team, so they can't use the trial system to communicate, they can only rely on their eyes and feelings.

The instruments here gave Xia Mingdong a feeling very similar to that of a carrier ship, with the same three-dimensional screen, coordinate scales and complicated buttons.

On the screen of the instrument, the ground is not the real earth, but a plane that is much smaller than the earth. As Xia Mingdong guessed before, it is not the whole earth, but a fragmented small world.

The detection instruments have been continuously recording the temperature and vector changes of the ground.

On the instrument, the floating city is a small floating island suspended above the ground, which also has temperature and vector records.

Ground vector: 9.8N/kg

This happens to be the number and unit of gravity.

The vector here is the gravity on the ground.

The force received by an object due to the attraction of the earth (ground) can be called gravity. Previously on the earth, the number of gravity was 9.8N/kg.

The so-called ground vector of crystal people should be the gravity they understood before.

The direction of gravity on the ground is always vertically downward, pointing to the center of the earth.

But the vector of the floating city is always the same as the gravity number on the ground, and the direction is opposite.

When standing on the ground, Xia Mingdong once looked at the Floating Void City from afar. The upper part of the Floating Void City is a reinforced concrete concrete human building, and the lower part corresponds to a black substance. Although it is too far away to see clearly, Xia Mingdong vaguely feels that it is not him. Any kind of metal I've seen.

If the floating city itself can have a vector, then this should be related to the black matter under the floating city.

The vector of the floating city is completely opposite to gravity, probably because the black matter is a special anti-gravity substance, which can have a vector opposite to the gravity of the ground itself, offsetting the gravitational force of the ground, so that the floating city can float still in one position .

It is not the floating caused by the huge energy consumption that he had thought before, but the gravity offset caused by the anti-gravity vector, forming a floating state.

This is the reason why the floating city is floating.

After Xia Mingdong figured everything out, he recorded a few numbers casually, and when he was about to find a way to submit the results, there was a loud voice outside.

A crystal person shouted outside: "Yes, there are enemies, mix in..."

Whoops, the crystal man who fainted in the toilet finally woke up.

Just let him see how the scientific research center under the dome works.

He turned his head and glanced at Cen Heng who was pretending to be doing things behind his back, and seeing Cen Heng looking over, he winked, meaning he should be more careful.

Hearing someone yelling, only a few crystal people around looked up, others continued to do what they were doing indifferently, and very few people would go to the door to look.

Xia Mingdong decided to be a very special person.

He pushed open the black crystal door, and saw the crystal man who had been knocked out by them before moving forward with extreme difficulty, with his hands clasped in a very embarrassing place.

And only a handful of crystal people around try to help him.

But the original crystal man No. 17 was like a frightened bird. Anyone who touched him would scream. He limped to the dark gray wall and pressed a red button on the wall.

In an instant, a red warning light was lit in the scientific research center, and the warning light flickered crazily above their heads, and the originally empty dome began to be covered by a metal dome.

Oh, they seem to be stuck in it.

But Xia Mingdong was not in a hurry at all, he leaned against the door frame calmly, waiting for the so-called person in charge of the scientific research center to arrive.

But it wasn't the person in charge of scientific research who came, but a few... security guards in black uniforms?

Xia Mingdong saw three security guards coming to Jingjing people to inquire about the situation. Two of them faced them sideways, one with his back to them, and the one with his back to them asked No. 17.

The person with their backs to them spoke softly and methodically, asking NO.17 little by little.

Xia Mingdong asked the crystal man who was "joining in the fun" beside him, "If such a big incident happened...there is no leader, only the security guards are in charge, is that okay?"

"Leader?" The other party looked at him strangely, "Are you out of your mind, where did you get the leader from?"

Xia Mingdong apologized, "Sorry, I'm new here, I don't know much about this place, my ex... passed away a few days ago."

The other party finally had an understanding expression on his face, "I probably know what you want to ask. There is no leader here. All tasks are assigned by the central computer in charge of calculation. The computer is the greatest invention of our crystal people so far. It can Let us get all the calculation results we want, and just accept the task according to the calculation results."

...It turned out to be machine-controlled.

There is no one in charge here at all.

Crystal people especially believe in their own inventions and creations, and they don't even need a person in charge, just a computer operation is enough.

So……

Xia Mingdong, one of the murderers involved, simply let go of his courage and walked over.

The so-called darkness under the lights may not be as good as him.

When Cen Heng saw Xia Mingdong's actions, he almost gasped and died on the spot. What made him even more astonished was that Ning Ge walked behind Xia Mingdong.

Cen Heng: "..."

They are all bosses, he can't afford to mess with them.

Xia Mingdong walked to NO.17, and asked calmly, "What happened?"

"Someone has invaded." He explained to one of their security guards sideways before: "There have been two consecutive attacks today, and it is suspected to be related to people on the ground, but no trace of people on the ground has been found so far."

"so……"

The security guard with his back to them has been asking about NO.17——

"Have you seen the other person's appearance clearly?"

"I only saw one, and it was quite fat."

Roughly speaking, it seems that NO.17 did not remember Cen Heng's appearance very clearly.

"Then if you see it again, can you recognize it?"

NO.17 nodded.

Xia Mingdong's heart moved, he took a few steps, and stood on the other side of NO.17 from a different angle, finally seeing clearly the security guard who had been facing away from them.

It seems to be the security guard at the gate who checks the pass, which is their ID number.

Xia Mingdong suddenly found that he couldn't remember the appearance of the other party.

At that time, he had been thinking about what to do when he came in, and he hadn't paid attention to the security guard. The other person's appearance seemed to be the type that could be easily forgotten in the crowd, just like the character of passerby A, with a vague appearance.

Recalling it again, what I saw at that time seemed to be covered with a layer of white mist, and I was not clear.

But under close observation, Xia Mingdong suddenly discovered that the other person's appearance was not like this.

The man's appearance was gentle and elegant, with a very refined temperament, and there seemed to be a smile on the corners of his brows and eyes.

Xia Mingdong raised his eyebrows and revealed a shallow smile.

He had only seen this feeling in one person——

Trial officer ABJ

It seems that he finally found the trial officer HS this time, another seemingly inconspicuous but actually very important role——

Security of the scientific research center.

Oh, it should be the leader of the security team.

After listening to No.17's narration, Xia Mingdong speculated that it was the security guard of HS, and said: "According to what you said, if the other party has not left here, we can close the dome for screening, but this will definitely affect tomorrow's plan .”

After hearing this, NO.17 said directly: "There is no need for closed screening, I believe the other party can't do anything that can really disrupt the plan."

Xia Mingdong slowly raised a question mark.

Crystal man... so confident?

"Okay." The HS reserve officer nodded with a smile, "Then I respect your opinion."

The other party left, and the originally closed dome slowly opened, NO.17 planned to drag his unsure body to Vector's laboratory.

Xia Mingdong immediately rushed ahead of him to the vector laboratory, walked up to Cen Heng and said in a low voice, "Follow me."

He told Ning Ge: "You and Ren Sheng block Cen Heng."

Although Cen Heng is a little bigger in size, it is only horizontally large, not as tall as Ning Ge and Ren Cheng vertically, and the two of them together are enough to block Cen Heng.

When they walked out, NO.17 was walking in, glanced at them indifferently, and skipped it directly.

Cen Heng's heart was almost in his throat, and then he found that the other party just passed by so lightly, and didn't notice him at all.

Cen Heng: ...?

After walking a certain distance from the vector laboratory, Xia Mingdong said, "Let's go, let's visit the HS reserve."

Cen Heng's eyes lit up: "Fourth brother, have you found out who is HS?"

"I found it, let's confirm it at the end."

Cen Heng: "How do I confirm?"

Xia Mingdong rubbed his chin, and said slowly: "Trial officers... seem to care about personal property in general."

Cen Heng: "?"

The author has something to say:

Xia Mingdong: We are all ordinary people, there is no need to pretend to be elegant
