At this moment, everyone's attention was focused on Zhou Hai.

Han Aya watched Zhou Hai gradually move towards the equipment full of sci-fi atmosphere, and the whole person held her breath, and she was a little nervous for some reason.

He Ping and Jiang Lei stared at Zhou Hai with their eyes, clenched their fists, and were extremely nervous in their hearts.

"I don't know if he'll be able to get through." Zhang Zhe's eyes narrowed.

Zhou Hai's face was indifferent and he arrived next to the detector.

"Go in and sit down." A female doctor greeted her, with a young face, about twenty-seven or eighteen years old, surrounded Zhou Hai and motioned for Zhou Hai to enter the detector.

Zhou Hai nodded, stepped into the detector, and sat in the soft seat set up in the center, and the female doctor put on a seat belt and related detection sensors for Zhou Hai.

"Relax, and if you can't bear it, call for help immediately." After doing all this, the female doctor smiled and reminded softly: "Are you ready?" ”

Seeing the young female doctor's smile, Zhou Hai subconsciously remembered the female doctor he had met, swallowed his throat, and nodded: "Okay, I'm ready." ”

To be reasonable, that physical examination was like a nightmare.

"Start the device, 1st speed."

The female doctor nodded, gave Zhou Hai a gentle smile, stepped aside, and gave a hint to the other female doctor.

The female doctor who is in charge of controlling the switch of the device, gets the instructions, her face is calm, she presses the switch, and activates the multi-dimensional space rotation detector full of science fiction atmosphere, and enters the slowest gear.

"Drop!" The device is powered on, and a dazzling and attractive green indicator lights up.

Immediately afterward, the entire system is activated, and the interior seats rotate in a clockwise direction at a rate of one time per second.

Sitting in the dazzling and rapidly rotating seat, Zhou Hai closed his eyes lightly, his breathing was steady, and his face was still the same.

Physiological data such as heartbeat data and pulse are collected by the miniature sensors of the device that are close to the body, and transmitted to the computer not far away through the wire.

At this time, everyone's hearts were raised, and a few people's faces were a little ugly.

This multi-dimensional space rotation detector is far more advanced than the electric swivel chair used by the Air Force for recruitment and physical examination, and the degree of testing of the vestibular organs and balance system of the body is not at all a level.

"Second gear, official timing."

After observing Zhou Hai's physiological condition with both eyes and confirming that there was no abnormal reaction, the young female doctor gave new instructions to her companions who were staying on the console.

The female doctor in charge of controlling the device nodded, and increased to second gear.

The second speed, about two rotations per second, is the standard speed of the official assessment, and only if you insist on this speed for 120 seconds will it be counted as a valid result.

The speed increases dramatically, and the interior seats rotate clockwise twice per second, creating a kaleidoscope of detectors.

"Gollum ......" looked at the high-speed rotating detector, and many candidates couldn't help but swallow their throats, their eyes straight.

Marxist-Leninist, this cliff is to play the rhythm of the dead!

The young female doctor had a solemn face, standing outside the safe area, her eyes staring at Zhou Hai, who was spinning at high speed, and said with a straight face: "Classmate, what do you think?" ”

"No problem." Zhou Hai heard the young female doctor's words and responded.

At this time, Zhang Zheng, who was expressionless, came to the young female doctor and gave the latest instructions: "Make it more difficult for him." ”

"Okay." When the young female doctor heard Zhang Zheng's words, she was stunned, her eyes showed some confusion and doubt, she nodded, and said to her colleague: "Start the multi-dimensional irregular movement mode." ”

When the female doctor who controlled the device heard this, her face was calm, and she replied while controlling it with both hands: "Start the multi-dimensional irregular movement mode." ”

"Da!" The mode switch is pressed, and a crisp, short sound is heard.

"Buzz!"

In an instant, the multi-dimensional space rotation detector, which spins at a high speed twice per second, suddenly changes, and the central rotation device changes from clockwise to counterclockwise.

After a few seconds of high-speed rotation in a counterclockwise direction, the central mechanism changes again, becoming the clockwise rotation it had before.

Clockwise, counterclockwise, the direction of each rotation is held for an uncertain time, some are two seconds, some are ten seconds, some are five seconds, and then they are changed.

Zhou Hai, who stayed on the detector seat and was tightly restrained by the seat belt, was like a spinning top with high-speed spin, and the irregular movement made his mind a little dizzy, and there was a hint of dizziness.

Such high-speed irregular spin movements are extremely challenging for the vestibular nervous system of the human body.

Fortunately, after more than ten seconds, Zhou Hai's vestibular sensory organ returned to normal, fully adapted to this high-speed irregular spin movement, the dizziness disappeared, and the perception of spatial attributes and body control were restored.

"Oh my god, do you have to change direction?"

"Damn, how are you going to play this?"

Seeing Zhou Hai being frantically thrown around, the many candidates who were observing in the testing room were all dumbfounded and in a state of bewilderment.

God, what's going on?

Do you want anyone to pass the assessment?

Originally, the difficulty of the multi-dimensional space rotation detector was far greater than that of the rotating electric chair during the physical examination, and now, the direction of rotation movement must be changed!

Changing the direction of rotational motion, what is the concept?

In a word, people who are not dizzy will vomit directly for you.

Change the direction, and no one does not vomit.

You must know that the vestibular nerve organs of the human body are complex and fragile, and extremely sensitive.

The average person spins on itself, and at most ten or so turns, they will be dizzy, nauseous and retching, and lose control and perception of their body.

People who are gifted or trained to use some technique during rotation and keep their eyes firmly focused on a target to relieve pressure on the vestibular nerve, but even then they can't support it for long.

If a trained ballet dancer is asked to rotate for a period of time and then change direction, the vestibular nerve organs will react violently in a short moment.

When recruiting for physical examination, everyone made rotating electric chairs, and most of them used this anti-vertigo method.

However, in today's multi-dimensional and three-dimensional background, what kind of trouble is the irregular high-speed spin movement?

Do you want someone to pass the assessment?

At this point,

At this moment, all the candidates looked at the detection equipment full of science fiction in front of them, and the vast majority of them looked extremely ugly.

"Questions? Schoolmate. Standing outside the safe area, the young female doctor asked Zhou Hai a question with a serious face.

As is customary, she does not ask questions to interfere with the test takers, but the boy in front of her is undergoing the most difficult assessment.

Second-gear speed, multi-dimensional irregular movement mode, without training and relying entirely on talent, the two add up, and there is one in 100,000 people who can successfully hold on for 120 seconds.

150 seconds?

So far, the young female doctor has seen twenty people.
