The neural exchange device was still a few days to be made, and the recruits who came to test the neural load arrived first, a total of 30,000 people.

With the screening conditions given by Qin Ran, the pass rate of this batch of recruits has increased significantly, 30,000 people, 311 people passed the test, plus the previous 254 people, a total of 565 people passed the first round.

However, although there are many recruits who have passed the first round, Qin Ran estimates that the elimination rate of the second round is estimated to be higher than that of veterans, because this group of recruits are all from Tiannan and Haibei, and their life resumes are different, so it is difficult to find only resonance, and many veterans have served for several years, and their resumes are similar, which is easier to resonate.

In order to make it easier to identify the possible successful neural connections between those people, Qin Ran asked Wang Cheng to do a survey of these 565 people, and then draw a table to summarize their personalities, family backgrounds, life resumes and other similar or identical people, which can reduce the number of trial and error, there can be no 565 people, one by one, one nerve exchange once, 565 people, each nerve exchange 564 times, even if each failure only loses the memory of a certain point in time, but so many times cumulative, It is likely that the subject will lose important memories or have complete amnesia, which would be troublesome.

"Qin Gong, can I also join the God Exchange Test?" When Qin Ran finished arranging work, Wang Cheng suddenly made a request.

"You?" Qin Ran glanced at him in surprise and asked, "Do you think you will resonate with them?" ”

A person engaged in scientific research, a group of soldiers, the two can't fight with eight poles, how can they resonate?

Wang Cheng did not answer directly, but handed a document to Qin Ran.

Qin Ran opened it and saw that it was a personal resume.

"Wang Xiaohu?"

"Yes, it's him, he's my cousin! I'm 22 years old, I'm three years older than him, we grew up playing together, and we went to the same school, but in different grades. I'm in sixth grade, he's in third grade, I'm in my junior year of high school, he's in my freshman year of high school, I'm in my junior year, he's in my junior year of high school, I'm graduating and working, he's still in my third year of high school.... Well, he didn't do well in the college entrance examination, he stayed in a few grades, and finally finally got a junior college exam, and he only graduated this year....."

"Okay, you can try it!"

Seeing that Wang Cheng was so confident, of course Qin Ran would not object, to be honest, he was very uncertain now, he really didn't know how many of the more than five hundred people could pass the nerve exchange test, since Wang Cheng took the initiative to ask for help, then Qin Ran was naturally willing.

Three days later, the neural exchange device was finally built, which looked like a turnstile, divided into four areas, and could support four people for neural exchange testing at the same time.

But for the sake of insurance, Qin Ran decided to test in pairs first, to make sure that there was no problem, and to test four people at the same time.

The researcher checked the device again and confirmed that there were no problems, and testing began.

"The first group, Wang Cheng and Wang Xiaohu, please get ready!"

The researchers on both sides put on the 'thinking hats' for each of them to confirm that the data connection was smooth.

Thinking hat, in fact, Qin Ran doesn't like this title very much, he thinks it should be called a combat helmet, the helmet that can be used for testing does not have other functions, maybe it is more appropriate to call it a thinking hat.

The thinking cap is densely packed with 300 nanoneedles, which can unknowingly inject a relay gel into the subject's capillaries, which can be transmitted to the cerebral cortex through blood circulation, and then unfolded.

The relay gel is a bright yellow particle that is stored in the interlayer of the mask of the thinking cap, and the surface looks like a mask on the mask.

The preparations are complete and the tests are officially started.

"Neural exchange is initiating, 15....14.....13.....12....."

As the countdown begins, the relay gel decreases at a visible rate, like the potion in a bottle when a needle is slinged, slowly decreasing.

Of course, the consumption rate of relay gel is not comparable to that of a sling needle.

The reason why the relay gel is stored in the mask compartment is to better and more intuitively show the progress of nerve exchange, whether it is the driver or other people, it is like a scale, as long as the relay gel is consumed abnormally, it will immediately stop the nerve connection between the two sides.

Obviously, the nerve exchange test of Wang Cheng and Wang Xiaohu went well, and in the expectant eyes of everyone, the relay gel was finally completely implanted into the bodies of the two, the bright yellow color disappeared, and the confused faces of the two were revealed on the mask.

At this point, the countdown is just over.

"Neural exchange connection successful!"

Hearing this broadcast, everyone at the scene was boiling for a while.

"It worked, it finally worked!"

"I was so nervous just now, but... Nothing went wrong! ”

.......

Among them, Dr. Wan Li was the most excited, and her lips were trembling right now.

She knew that she was not as good as those authoritative experts, and she was lucky to be part of the Giant Mecha Project, but now that she had made a major academic breakthrough, it was enough to make her famous in the entire academic world.

Of course, Wan Li knew that all this was brought by Qin Ran, and she wanted to seriously thank the other party for her guidance and help, but she was not good at words, and a thousand words came to her mouth, and there was only one sentence left.

"Qin Gong, thank you!"

"It's nothing, I'm just talking about it, it's you guys who really work hard!" Qin Ran smiled, looked at Wang Cheng, who had just recovered from his confusion, and said, "Actually, I was also surprised, but I didn't expect this kid to always surprise me." ”

"I... I did it? Wang Cheng took off his thinking hat, was stunned, and asked Qin Ran.

"Yes, you made it!" Qin Ran replied with a smile, then glanced at Wang Xiaohu and corrected his wording. "You should have succeeded."

Hearing this, Wang Cheng patted Wang Xiaohu's shoulder excitedly, "Xiaohu, do you hear it, we succeeded!" Hehe! ”

Wang Xiaohu grinned and smiled at this time, with his slightly chubby figure and harmless face, he looked a little silly, which made Qin Ran have a delusion, could it be that the memory of a fool is easier to be deceived?

Of course, Wang Xiaohu can be admitted to university, he is definitely not a fool, at most the nerve reaction is half a beat slower, even if the fool is more likely to succeed in neural connection, there is no need for experimental demonstration, what if the demonstration is successful, you can't let a fool be a driver.

originally thought that Wang Cheng had made a good start, and the subsequent tests would have a smooth ride, but it turned out that probability could not be fully applied to practice.

After the three-day test was completed, only two of the 564 people had a successful neural exchange, with a success probability of 0.35%, which was much lower than the neural load test.

Although this result was expected by Qin Ran, he was still not very satisfied, after all, before the result came out, Qin Ran still had some illusions.

Qin Ran was ready to report the results, and asked for an increase in the number of tests by the way, but thinking that it was enough for Wang Xuezheng to estimate that the two of them could succeed, and now there are two additional Wang Cheng brothers, it is estimated that Wang Xuezheng is already satisfied with this result and will not approve of increasing the number of tests.

Therefore, Qin Ran planned to only report the results and not make any requests, but before that, he had to ask Wang Cheng what he thought.
