The end of technology.

But to precisely control where the lightning strikes, and even let the lightning fall directly from the sky, he wouldn't believe it if he was killed.

Soon he took off the belt and gave it to the staff next to him. He put on a rope that Ning Ru found for him in the dormitory, and asked the staff to help him find a pair of shoe covers. Wait a minute. Send it to him.

Then he turned off the phone in front of Ning Ruo, put it back in his pocket, and then said to Ning Ruo, "Is it alright now?"

"Let's go." After speaking, Ning Yu walked out of the bedroom first.

……

The test took place at the school's second football field.

The school was still on summer vacation, and the playground was not as lively as it was when the school started, but Ning Ru still greeted the school security department early, and the entire football field had been completely closed.When Ning Yu arrived with Dominette, the playground was empty, and security guards blocked all the surrounding intersections on the way.

This posture made Dominette feel a little surprised. Could this guy be serious?

Soon, Ning Ruo took Dominite to the northeast corner of the playground. Here Dominite saw a large instrument facing the sky at an angle of about 75 degrees. There were also many cameras set up around the playground. Aim at the center of the playground.

Around the big instrument, there were still two Chinese people standing there. Dominette noticed that they were obviously surprised when they saw him.

"This self-proclaimed Harvard professor must come with me to observe the experiment. This is President Chen of our university, and Minister Luo of the security department." Ning Ruo casually introduced the two sides in Chinese and English, and then took care of himself Since the beginning of debugging the instrument, it is none of his business as to how the two sides communicate.

……

Chen Yonggang and Luo Weimin came here, of course, not by accident.

Because this test is dangerous, the venue needs to be arranged in advance, so Ning Yu made a report to Chen Yonggang yesterday, and agreed on the approximate time and exact location of the test.

Of course, this time and place are naturally booked in March.

After taking into account the weather conditions, as well as Dominite's scheduled flight time, and the school's temporary accommodation for Dominite, the plan was directly drawn up in March.

In fact, according to the original plan, I didn't expect that after Dominite arrived at the University, he didn't go to the room to rest first, but took the initiative to find Ning Yu.

Because under normal circumstances, after taking the plane for more than ten hours, everyone should choose to settle down first, then take a shower and get a good sleep.

The guest house in the school is not too far from the second football field of the school, and the straight-line distance is about 500 meters. More critically, when the car that picks up Dominite goes from the school gate to the guest house, it must pass through the blocked area.

In this way, during the negotiation process between the two parties, there is a high probability that Dominite will be interested in this test.

It would be best if he offered to come and watch the test.Even if he had no interest in this experiment, when he was resting in the guest house, he happened to be able to see the lightning falling from the sky from the window, which would make him curious again.

All in all, in March's calculations, Dominite was one of the spectators who had to be part of this trial.

If Dominette knew that there were so many calculations, he would probably be very upset and start to admire Ning Yu's acting skills.Because he was just at the door of Ning Yu's dormitory, he really thought that this reckless student would ask someone to drive him away directly.But for Ning Yu, it was actually acting in his true colors.

After all, humans and machines think differently.Ning Ruo didn't care whether the man would be mad at him or not.

……

As for Chen Yonggang and Luo Weimin, the former one had already said that they would come to see the experiment after listening to Ning Wei's idea; the latter was here to maintain order and accompany the principal to observe the experiment.

To be honest, Chen Yonggang didn't really believe that Ning Ruo's idea of ​​trying to control thunder and lightning would be successful.

After seeing Ning Zhi's report, he also specially logged into the index system of the school library to see if there was any research on this aspect at home and abroad.

But most of the research on lightning in the database is how to reduce disasters, such as the setting of lightning rods and so on...

These are obviously very different from the contents of Ning's experiments.

After all, according to the content reported by Ning Wei, this test consists of two parts. The first step is to trigger lightning when the cumulus thickness is sufficient but no lightning conditions are formed; the second step is to make the falling lightning strike the tile accurately. The target on the ground of a wide square, and the error is limited to within 5mm.

how to say……

Because Ning Ruo had won so many resources for the Tidal University, he had to give Ning Ruo this face, so he made great efforts to facilitate this experiment.

But the reason he came to observe the test was actually to comfort Ning Zhi for the first time after the test failed.

Of course, he also planned to persuade Ning Ruo to focus on mathematical research. These messy experiments can be discussed later when the time is more mature.

After all, such a laser generator with such a high power is also very expensive. It is said that in order to order such a big thing, Ning Ruo basically used up the scholarship that Fan Zhenhua helped him win.

Although Ning Ruo also said that after this laser generator is used, it will be donated to the school.But Chen Yonggang naturally didn't want to take Ning Zhi for nothing.

He also thought about it. After Ning Zhi failed in this experiment, the school would simply pay for this thing.Anyway, the school is not bad for this equipment cost. As for the future use, it is another matter.Even if it is really useless, it can be resold through the school.

In short, this small amount of money must not let Ning Ruo lose.

The only thing Chen Yonggang didn't expect was a random experiment in the school in order to make Ning Ruo give up on this kind of whimsy, and even the Harvard professor came to observe it.This made Principal Chen a little troubled...

It's not that I feel that this experiment needs to be kept secret, but if all my own people are present, it doesn't matter what happens, and no one will feel ashamed.But the presence of so many outsiders made him unhappy.

Chen Yonggang is a person who takes a lot of face, especially in front of those foreigners he usually calls him.

……

"Welcome, Professor Duncan. Please forgive me for not being able to pick you up at the airport because of this important experiment. However, you just got off the plane, don't you need to rest first?"

To be the head of a school, Chen Yonggang's English level is still very good. He probably won't pass the CET-[-] test, but there is no problem with simple communication in life.

"No, Principal Chen, I'm actually not tired. And I'm very interested in what Ning Yu is doing." Dominite glanced at Chen Yonggang and replied calmly.

From the attitude of the reception staff, Dominette Duncan probably understood the principal's attitude towards him, and naturally he would not be too enthusiastic.

Not to mention that this Harvard professor has a proud temperament. He just finished eating deflated at Ning Yu's place, and he is very angry at this time.

However, when he saw that Chen Yonggang and another so-called head of the school security department were both wearing sweatpants without belts, and the shoes on their feet were also made of thick insulating materials, it made his resentful mood a little better. .

This at least shows that Ning Yu didn't deliberately target or humiliate him just now, but really thought that the experiment would be successful for his safety.In this way, even if the attitude is cold or even rude, it can be reluctantly accepted.

This also made Dominette decide that after the experiment is completed, if there is no effect, he can give the student a little bit of sympathy.

But Dominette's answer made Chen Yonggang feel less beautiful, but he couldn't force people to drive the Harvard professor away.After all, this exchange really has to be said that Yanbei University has taken advantage of it, and the harmony on the surface has to be maintained.

It's just that without speculation, the two of them have no interest in chatting.

For Chen Yonggang, he will naturally be more enthusiastic about Dominite in public, showing the Chinese people's hospitable and polite demeanor, but he is too lazy to act in such private occasions.

Standing in the middle of the two, Luo Weimin wanted to interject a few words to liven up the atmosphere, but he was helpless. He couldn't speak English, nor could he understand that...

So, although the three of them were all standing in the same position, everyone was silent.

……

Ning Yu ignored this.

He just re-checked the laser generator according to the instructions to make sure that this thing will not have problems in the next test link.

It's not that I'm afraid of affecting the test results, the key is that if the thing fails to work properly after a while, the laser is not fired, but the lightning in the sky is drawn down, or it is delayed, and the lightning over there will come down, and the laser will be fired here. If you go out, it's not easy to explain.

Can't write in the thesis that he learned the lightning trick?

After confirming that the working state of the machine was correct, Ning Yu ignored the silent three people, but silently picked up the bag and prepared to arrange the special metal target belt.

This thing should be placed in the center of the playground, and the three corners should be fixed. Finally, a layer of protective film should be torn off. The special material coating layer that wraps the March hair extract will first react with the air, gradually fail, and then pass through The matter replaced by the particles in the medium space will be exposed to the air in its most primitive form...

At this time, let alone laser-induced, even if there is no laser, as long as the conditions of the cloud layer in the sky are sufficient, countless particles in the cloud layer may start to become violent, which will intensify the movement of the cloud layer and form lightning, and then directly chop up.

When explaining the principle in March, Ning Zhi felt that this was actually very similar to the working principle of the rejection response of the human immune system.When the immune system finds cells that do not belong to the body, it directly sends defense cells to engulf them.

So for these materials to exist in nature, they need to be coated with substances of this world on their surface, as if glycans can form a protective shell that the immune system cannot recognize.

In this regard, Ning Yu could only sigh that the natural world is indeed magical enough that such a rejection reaction that is very similar to that in the human body can occur between substances.

"I'll go with you." Seeing Ning Ruo going to the center of the playground, Dominite said quickly.

Standing here he felt suffocated.

Ning Yu glanced at Dominette, thought for a while, then handed over the bag in his hand, and answered concisely, "Okay."

Dominite subconsciously took the bag in Ning Ruo's hand, which felt heavy, but quickly realized that he was using it as an assistant again, and couldn't help but angrily said, "You asked me to take it?"

"Otherwise, what are you going to do?" Ning Ruo asked strangely.

Dominette suddenly didn't know how to answer.

Could it be that he just wanted to see if Ning Ruo cheated?

As far as the attitude of these people at the scene towards him, Dominette dare not speak so nonsense.

Although the information he got said that the security of the Huaxia capital is very good, there must be a premise, at least he can't take the initiative to provoke trouble.

Fortunately, the bag in my hand is actually not heavy, and the heavier one is psychological pressure.

He came to Huaxia to be a teacher for Ning Ruo, but on the first day he arrived at the university, he was like a humble laboratory assistant, carrying the tools that he needed to use in the upcoming experiments, and followed Ning Ruo step by step. I don't know if the tall headmaster behind him was looking at him with mocking eyes.

Dominite didn't even have the courage to turn his head to look at it, it was too aggrieved!

Fortunately, the playground is so big, and before Dominite complained and wanted to explode, Ning Yu had already taken him to the center of the playground.

"Put down the bag." Ning Yu explained.

Dominite, who had been appointed, silently put the bag beside Ning Yu.

Looking at Ning Ruo, who had already squatted down, only then did he realize that the turf in the center of the playground had been driven into the grass in advance with three angle-steel nails the size of a thumb, and some modifications were made to reveal the end that could screw the nut and stick out from the ground. About 5 cm or so.

At this time, Ning Yu was reaching out and shaking the three screws forcefully a few times. After confirming that the screws were stable, he said without looking back, "Give me a piece of the target of the bag."

Dominite was stunned again, opened his mouth, and said nothing after all, silently took out a triangular target covered with a layer of plastic from the bag and handed it over.

Human adaptability is powerful after all.Once he accepts the setting that he is an assistant at this time, in fact, he does not feel that this request is abrupt.

Ning Yu took the triangular target, tore the plastic covering on the outside, and then directly aligned the round holes at the three corners of the target with the screws exposed on the ground.

"Bring me the nuts in the bag."

This time, Dominite cooperated very well. As soon as Ning Ruo spoke, he had already handed over the nut he needed.

Although he no longer speaks, his inner activities are very rich.

He has already decided that he will be ridiculing this hateful guy later.

Ning Ruo quickly tightened the nut, and then shook the triangular target again. After confirming that it was fixed, he clapped his hands, stood up, looked up at the layers of clouds in the sky, and said: " Come on, don't forget your bag."

After speaking, he turned his head and walked out of the playground.

……

Ning Yu walked in big strides and silently counted the time in his heart.

According to March's calculation, it takes about 7 minutes for the coating to volatilize, with a margin of error of 30 seconds.

It's not that the calculation in March was inaccurate, but that Ning Ruo did not conduct an accurate laboratory analysis of the purchased coating materials, because it was not necessary.

Even an error of 1 minute is within the acceptable range.

After all, the error tolerance rate of this kind of experiment is actually very large.He only needs to fire the laser within 5 minutes of the paint being exposed.

The chain reaction at the macro level will take time.Even in the paper, this waiting time is not fixed, it will be affected by external uncontrollable factors such as cloud layer thickness, air humidity, etc., so there will be no flaws in this aspect.

Of course the necessary preparations are still to be made.

Soon, Ning Yu walked to the laser generator again, and said to Luo Weimin, who was still standing there waiting, Chen Yonggang: "We can't stay here, we have to go to the flat ground. Stay away from trees and all things that are a certain distance above the ground. , and then squat down as required."

Although he didn't have much confidence in this test, Chen Yonggang's attitude towards Ning Ruo had already decided that he would definitely do as required.

When the principal has taken this attitude, Luo Weimin naturally won't say much.

As for Dominette, he has even been an assistant, and he will not express his opposition at this time.

It was only when he saw that Ning Ruo followed them to the spacious road opposite, he couldn't help but ask, "That thing doesn't need to be controlled?"

Ning Yu was really speechless this time. She stopped, looked at Dominette, and asked seriously, "So you haven't seen wireless remote control technology in the United States?"

As he spoke, he took out a black remote control from his pocket and shook it in front of Dominette.

For the first time, Dominette felt that he was so talkative.

In fact, whenever he sees a plot where the villain dies in a movie theater with too many words, Dominette will always ridicule the IQ of the director and the screenwriter in his mind. He can clearly solve the battle quickly, so why must he talk so much?

But today he realized that art really comes from life.

Sometimes when you don't say anything, you can live peacefully.But the mouth is always a little faster than the brain, so that it looks extremely stupid.

The moment Ning Yu took out the remote control, he even wanted to explain to Ning Yu that he was not so stupid at ordinary times, probably because he had been on the plane for a long time, and fatigue made his mind react for a while.

Fortunately, his IQ was finally online this time, and he forcibly held back his explanation.He had already decided that he would never say anything more until the experiment failed.

Without the interference, the four of them soon arrived at the predetermined position, and then squatted down according to the actions that Ning Ruo had explained in advance, and wrapped their hands around their knees.

Ning Yu directly pressed the remote control.

Watching the machine start, and about half a minute later, when a laser rushed towards the clouds, Dominette finally understood that the big guy was a laser generator.

Ning Ruo watched the laser generator work, and finally put a hanging heart back to her stomach.

How should I put it, the equipment that has nothing to do with the whole experiment happens to be the most important part of the experiment.

Now we can only wait. If the test fails, it probably only means that there is something wrong with the calculation in March. Anyway, the result will be available in two or three minutes.
