Zhai Qinghe sat in a room with a simple layout, with only a snow-white bed behind him, and it could be seen that it should be a hotel or something.

But other than that, there was no information, even the curtains behind her were tightly drawn.

Everyone had just seen a little hope, and now that hope was gone in an instant.

Lin Yi sighed: "She even pulled the curtains tightly, probably just to prevent us from looking at the scenery outside to judge her location, how to find her?"

Jian Zhizhen took his mobile phone from Qin Yubai's hand, adjusted the volume to the maximum, and listened carefully.

Then he looked at Qin Yubai: "Listen, the sound of the waves."

In Zhai Qinghe's back voice, a slight sound of waves could indeed be heard.

Qin Yubai lowered his eyes and glanced at her, and instantly understood what she meant.

The base is very close to the shore and you can hear the sound of the waves.

And the place where Zhai Qinghe is located should be a little farther away from the coast, and the sound of the waves is very slight, but it can still be heard.

Jian Zhizhen held the mobile phone and gently touched the device on his wrist to wake up Jian Ji.

"Xiao Ji, record the sound for me, and separate the sound of the waves from the inside."

Jane is a ruthless royal sister who is a few words, and after receiving the order, she replied "yes" and immediately started working.

Qin Yubai did want to go with Jian Zhizhen, and without discussing it with her at all, he got up and left.

He went to the courtyard and instructed Qin Wang to measure the wind speed outside.

The other guests were a little stunned when they saw that one of them was on the sound track and the other was measuring the wind speed.

Zhou Sui simply asked directly: "I know you two must have come up with an idea again, can you talk to us about what is the solution?"

Jian Zhizhen thought for a moment and explained in simple words: "You should have done a classic math problem in elementary school: the speed of sound propagation is 340s, and after 10 seconds, how far away can people hear the sound?"

As soon as the words fell, Li Nanyan immediately reported the accurate answer: "3400 meters!"

"......" is great!

But that's not what Jian Zhizhen wants to say.

She continued, "I mean, sound can calculate the distance between two places. After analyzing the sound of the waves in Zhai Qinghe's background environment, and then comparing it with the sound of the waves here, we can calculate that the same sound of the waves is transmitted to our base, and there is a difference of a few seconds between it and Zhai Qinghe."

Saying that, Jian Zhizhen glanced down at her wrist, "Our 23rd century equipment is very advanced, even if we are talking here all the time, she can accurately record the sound of the waves."

Jian replied coldly: "Pass the prize."

Everyone nodded one after another, Jian Zhizhen said very well, they all understood.

Only Lin Yunfei had a cold face and didn't say a word.

She is now beginning to understand Zhai Qinghe's feelings.

Who wants to watch Jian Zhizhen be in the limelight all the time!

She can only be glad that she is not live now, and the audience can't see it.

However:

[lzyct: Teacher Jian's small class is starting again! This time, we will give you the application of primary school knowledge points in real life! 】

[Black bean sprouts: Lin Yunfei's metaphysics is useless at all at the critical moment......]

[Painful beautiful man: Then Jian Zhizhen's primary school knowledge points must be useful? ] Theory is theory, reality is practice, you can really calculate it and find people, you can boast about it! 】

Zhou Sui glanced at the courtyard, and then asked Jian Zhizhen, "Then why did Qin Yubai go out to calculate the wind speed?"

"In a calm, windless flat area, the wind speed is 340s, but the speed of sound is very susceptible to the speed of the wind, and the upwind propagation will reduce the volume of sound, and the height of the wind will have different effects on the speed of sound propagation. Slight wind speed can be ignored, but the wind and waves are loud at the beach, so the wind must be taken into account."

As soon as Jian Zhizhen finished explaining, Qin Yubai had already returned.

Qin Wang, as the most advanced assistant in the 23rd century, was at ease in a few minutes

It is easy to draw a very accurate graph of the wind speed difference.

Jian also separated the sound of the waves in Zhai Qinghe's background sound, matched it with the sound of the waves here, and calculated the interval speed of seconds.

Jian Zhizhen comprehensively calculates all the obtained data.

Soon, several possible directions were obtained.

When you open the map, you can see that only one of the locations is a B&B hotel.

In other locations, what are kindergartens, fruit shops, and restaurants...... It should not be possible to have such a room.

The audience took another vivid and specific primary school math lesson, and they all said:

[Yan Wei is open: The facts show that learning mathematics, physics and chemistry well is more effective at critical moments than some can be pinched. (I don't mean to step on a certain metaphysical girl, but just encourage everyone to study hard). 】

[Colors that are not allowed to be astringent: What does this tell us?] Tell us to trust the science! This wave is really the victory of primary school science and advanced technology over metaphysics! 】

[Zi Yan: Metaphysics is also true, and there are some metaphysical masters who are really super powerful, but Lin Yunfei can't understand it! ] Lin Yunfei's personal behavior, don't rise to the entire metaphysical world! 】

[Painful beautiful man: Jian Zhizhen is just deducing the location now, has he really found someone? ] Don't look back, there's no one at all! 】

Although no one is sure where the person really is, at least there is a direction, so there is no need to guess here.

Lin Yi glanced at Jian Zhizhen and Qin Yubai gratefully, "I'll go over and bring her back right away."

The two of them also spoke together in tacit understanding: "We'll go with you."

Li Ze also rolled up his sleeves and said, "I'll go with you, in case I meet the same situation as the previous issue, if there is a barbarian situation, one more person can still fight together."

Seeing this, the others also said that they wanted to go together.

But Lin also felt that it was not good to go to too many people, especially some people who were not strong in combat or brain, and when they encountered danger when they turned around, they also protected them.

So he said, "Jian Zhizhen, Qin Yubai, Li Ze, the three of you go with me. The others stayed at the base and helped watch Zhai Qinghe online, if she wants to do something stupid, you should quickly send a barrage to dissuade her."

Lin Yunfei was originally very angry that Lin Yi didn't choose her, but once again felt her status in Lin Yi's heart, and was slowly defeated by Jian Zhizhen.

But as soon as she heard the latter words, she calmed down again.

Yes, she stayed at the base, and she could also use the number one account to urge Zhai Qinghe to commit suicide quickly.

Don't look back and be saved, she has to worry about this disaster all the time.

So she nodded obediently: "Okay, I will persuade Zhai Qinghe."

Subsequently, Jian Zhizhen went to pack a bunch of medicines and bring them with him in case of emergency.

Then, one group set off, while the other stayed at the base.

Lin Yunfei went back to the room alone, she wouldn't use her trumpet in front of these guests.

Zhou Sui and Xu Qiuyuan were sitting on the sofa, and Li Nanyan was sitting on the sofa opposite, both staring at Zhai Qinghe.

The audience in her live broadcast room also began to increase slowly, and they all posted there:

[Is yesterday's preview true?] 】

[If you hype, you can't die well! ] 】

[Hurry up, hurry up, I can't wait!] 】
