Fifty-two years have passed very quickly since the restart of the Union fleet...... During this time, everything was steadily advancing, nothing special happened, and no planets with intelligent life were encountered.

One of the most advanced classified experiments appeared in the Shanhai's illusory experiment, and its secrecy level was set to S-class, and all the members of the laboratory signed a confidentiality agreement.

There was a strange electronic sound in my ears, and the source of the sound seemed to be in the far reaches of outer space.

"The mind acceleration experiment is ready, and the current number of experiments: 1 person."

"Verifying identity, debugging parameters...... Please ...... later"

"Countdown to the experiment...... 3,2,1 start...... I upload consciousness and succeed in ...... Memory reading, successful ......"

"Thinking is accelerating...... 2x the speed ......"

"3x the speed, success!"

Zhang Yuan opened his eyes slowly, he felt that his head had become very strange, I don't know why, there was always a wonderful illusion that his mind was detached from his body, and there was no way to move flexibly.

No, not an illusion, but a real feeling.

He is personally completing a mind-accelerating human experiment. This kind of experiment is very dangerous, and if you are not careful, you will risk insanity and even a collapse of your sense of self. Fortunately, the content of this experiment was designed by himself and has a little controllability.

A not-so-difficult definite integral math problem appeared in front of him, and Zhang Yuan needed to concentrate in order to be able to solve it.

"What are you?"

"Can you have enough, set, medium, note, will, force?"

There was a vague sound from the outside world, but in Zhang Yuan's ears, the voice was one after another, very discontinuous.

The main reason is that his thinking has been accelerated to 3 times the speed of ordinary people, which is equivalent to the speed of the outside world being slowed down to one-third.

"It's been solved. The answer to the definite integral is ......"

Zhang Yuan wanted to speak, but found that his throat was a little uncontrollable, and his voice became so rapid and fast that outsiders couldn't hear what he was talking about. In this virtual world, there are a series of simulation devices, and his body movements are similar to those in reality.

He raised an arm, trying to make some gestures, but at this moment, he almost threw the arm in his face.

I finally calmed down, but I found that I couldn't manipulate my fingers flexibly.

At 3 times the speed of ordinary human thinking, everything seemed to him to be too slow, so that there were some problems with the control of muscles.

And these movements seem to others to be really awkward, like a crazy person, writhing around.

Zhang Yuan simply lay flat and didn't move, he sighed in his heart: "This is only 3 times the speed of thinking, and the body movement can no longer keep up with the thinking...... The control module of the entire body has to be rewritten, otherwise it will not be able to be used at all. ”

"It's hard to imagine thinking at a speed of 100,000 times, or even a million times...... Thinking and moving, a series of cuts must be made. ”

"If the quality of thinking can be further improved in the future, then humanity will indeed change dramatically...... This is a fifth-level civilization! ”

After a while, Zhang Yuan gradually adapted to the current state, and said the first sentence not very clearly: "How do you feel now...... Good...... Ability to concentrate...... The body is barely able to maneuver, very reluctantly...... Motion Module &......%??! ”

"It is advisable to use textual means...... Communicate. ”

"Please adjust the thinking speed to 3.5 times."

"Clear-white-." After a long time, a response came from the outside world.

For the staff from the outside world, their response was already the first time, but for Zhang Yuan, it was still slow.

In the laboratory, Professor Ichiro Yamamoto, who presided over this work, looked serious and said, "You guys check whether Professor Zhang's physiological indicators are normal......

The other staff hurriedly said: "I haven't found any big problems at present." However, the rate of brain waves has reached the expected level of the experiment, and if it exceeds the standard, there may be risks......"

"Now I'm trying to think 3.5 times faster. In case of an abnormality, stop the experiment immediately! ”

"Understood!"

The electronic sound came again: [Thinking Acceleration Restart, 3.1...... 3.2…… 3.3…… 3.5x speed, done. 】

As the speed of thinking enlarged again, Zhang Yuan felt that his head was a little dizzy, and he could even feel all kinds of chaotic thoughts coming one after another, like never-ending waves, wave after wave.

Ichiro Yamamoto saw the data indicators on the screen, and his face showed worry. He looked at one of the professors around him, and still held back his thoughts.

The frequency of the heartbeat exceeds two hundred beats per minute, and there is already a risk!

A calculus math problem appeared in front of Zhang Yuan's eyes, and the difficulty was about the same as the previous one. It takes a lot of attention and thinking to be able to solve this problem.

"No...... Difficult to decipher. ”

"I don't understand what it means."

All the words seemed to be beating, like tadpoles, and formed a strange vortex. Now he was like a patient with a high fever, unable to concentrate on his thoughts, and even the meaning of the title was a little difficult to understand, and the rate of breathing began to increase dramatically.

The heart is beating faster and faster!

Drops –

A security alert has been raised in the lab!

"Blood pressure is elevating and there is a risk of cerebral hemorrhage! The heart rate is beating faster than the safety boundary! ”

"With a thinking volatility of 413.5, there is a risk of a crash! Professor ......"

"Stop the experiment!"

Ichiro Yamamoto didn't dare to delay, and hurriedly issued an order.

[The experiment has been stopped, and the mind recovery program has begun...... 3.5…… 3.4…… 3.3……】

[Returned to normal speed.] 】

Even so, there were bursts of tinnitus echoing in my head, and the speed of my brain began to slow down gradually. But Zhang Yuan still couldn't hold on, and he mixed up all of a sudden.

……

When he reopened his eyes, he found himself lying in a hospital bed, surrounded by concerned colleagues.

"Wake up, wake up!"

"Don't say anything, do a full inspection first." A medical expert patted his chest and exhaled a cloudy breath.

After checking various instruments over and over again, the chief doctor finally announced that there was no big problem.

"Basically, the crisis is over."

"How many hours have I been in a coma?" Zhang Yuan rubbed his ears, and the strong tinnitus began to fade away, which meant that he himself had begun to return to normal.

An older professor said with a smile: "Because the experiment was interrupted in time, you must have been in a coma for more than 3 hours." This time you have set a record, 3 times the speed of thinking, and you can still focus on thinking, which is close to the limit of normal people! ”

"Although the body's athletic ability, there is no way to pass. It can't be helped. ”

Next, the staff began to report the experimental data this time, the normal human brain, plus the auxiliary brain assistance, to reach 2-3 times the speed of thinking is basically the limit, and there is no way to go faster.

The original human body has a certain degree of self-regulation, but at a higher speed of thinking, it begins to be unable to keep up with the rhythm.
