Inside the hot spring baths, the fog is shrouded, and it is basically difficult to see the situation on the other side.

It's just that when everyone is taking a bath, they always make some conversational sounds, so the sound of the girls laughing on the other side can easily be transmitted here.

"Sound travels faster in water than it does in air." Lin Xiao heard the sound of the conversation over there, and couldn't help but say something a little surprised, "Therefore, the water content in the fog is relatively high, and the speed of sound propagation is between air and water." ”

"I haven't paid attention to this." When Du Yu heard this, he didn't quite understand what Lin Xiao was talking about, so he shook his head and said, "I didn't study physics hard in middle school before, and I was messing around when I was in college, I really don't know what you said." ”

"Hehe, actually, it's nothing." Lin Xiao waved his hand and said, "If you have experience when you were a child, you know that lying on the train tracks, it is easy to hear the train whistle from a distance, but the sound in the air is much later. ”

"Oh, the density of steel is naturally greater than that of water, so the sound travels faster in it?" At this moment, Du Yu understood, but he still didn't quite understand, why did Lin Xiao say such inconsequential things?

After all, everyone is just here to take a bath, not to discuss some middle school physics knowledge, it is completely possible to say a little bit of wind and snow, at least you can tease the two beauties, why do you have to turn this beautiful thing into an academic seminar?

However, he had known Lin Xiao for a long time, so he would not ask Lin Xiao why he said this.

It's just that Shui Ling'er and Yao Tong have just changed into bathrobes and are walking over.

"What are you talking about? I just heard you guys discussing the speed of sound propagation, is that a valuable question? Shui Ling'er asked.

"There's no value." Lin Xiao spread his hands and smiled, "It's just boring, do I have any common language with Du Yu to pass the time." ”

"It's not funny for you to talk like that!" When Du Yu heard this, he was immediately very unhappy, "From the capital to Qingshan Province, how much suffering and how tired have I suffered with you?" You have wiped all this out without a common language now, do you feel sorry for yourself? ”

"Why, you still expect me to make a promise?" Lin Xiao asked rhetorically.

"My sexuality is very normal!" Du Yu immediately stated his position and took the initiative to get closer to Yao Tong to show his innocence.

Lin Xiao laughed twice and looked at Shui Ling'er and Yao Tong's figures.

Although the two women are wrapped in wide bathrobes, they are curvy, and they can still be seen, especially the skin is the same fair and tender, as if they can pinch the water, and they are really rare beauties.

Yao Tong's figure is more outstanding, especially the bulging chest, Du Yu, this kid is really blessed.

"We've got this pool covered." Du Yu walked over with them and stopped in front of a hot spring bath of about 20 square meters.

Lin Xiao nodded, feeling that although this pool was not too big, twenty square meters was enough for the four of them.

If you use an acquaintance, it's not an impossible thing to take a mixed bath, but you first have to wrap the whole pool to use it more securely.

Otherwise, it is indeed easy to have problems with everyone huddled together in the bath.

After the four of them went into the water one after another, they found that there was a small fish swimming in the bath, and there were many of them, and they were not afraid of people, they surrounded their bodies, pecked them with their small mouths, and felt that their skin was a little itchy, but it would not hurt.

"Hey, these are the little fish that live in the hot springs!" When Yao Tong saw it, he couldn't help but be a little surprised.

"Hasn't Miss Yao tried the hot spring fish service before?" When Shui Ling'er heard this, she asked with some curiosity.

As a wealthy woman worth tens of billions, Shui Ling'er must have seen these things, and she intuitively thought that Yao Tong, a child of the family, should also enjoy such treatment, so she asked this question.

"I've always been on missions in the open sea before, and I really haven't had time to try such a hot spring fish bath." Yao Tong didn't feel embarrassed to be asked like this, and replied calmly.

"Oh, you military people, always don't think about yourself. by. Shui Ling'er listened, but nodded and said.

Lin Xiao couldn't help but look at Du Yu, and said in his heart that Du Yu's family had found such a family affair for him, but he didn't know what kind of consideration he was in?

If it is speculated according to the general situation, Yao Tong should soon bid farewell to the specific tasks of the military, and it is very likely that she will be transferred to some civilian departments to work, after all, after becoming Du Yu's daughter-in-law, there are some dangerous jobs, and it is unlikely that she will be allowed to continue to contact with each other's families.

After all, women are indeed not as convenient as men in some military jobs, especially after marriage, family life, which also makes them not suitable to continue to stay in the army to perform those dangerous tasks.

"Well, anyway, you've always had a lot of memorable experiences." Shui Ling'er sighed with emotion.

Yao Tong glanced at Shui Ling'er with a smile, nodded and said, "Actually, it's just because they don't know each other's circles, if you work and live in an environment for a long time, you will get tired of it after a long time." ”

"Well, you have a point." Shui Ling'er thought for a moment and nodded in affirmation of Yao Tong's statement.

"These words are valid for everyone." Lin Xiao lay on the side, watching the little fish wander around his body, but he didn't peck any dirt, "Even if we were doctors at the beginning, we would feel the gap between work and interest, although I don't averse to treating diseases and saving people, but stylized work will always make people gradually lose those original ideas." ”

Lin Xiao's body is now difficult to produce any dirt, the little fish pecked around, and they couldn't find any dirt, and his skin was hard to hurt, and there was no cuticle for the little fish to peck off, so after a while, the little fish seemed to feel a little depressed and left its body one after another.

When Du Yu found out about this problem, he felt a little surprised.

"Hey, Lin Xiao, how dirty are you, even the little fish don't want to serve you!" Du Yu's words made Lin Xiao very annoyed and wanted to beat him.

But before Lin Xiao could refute, Du Yu said, "Don't believe it, it seems that a small fish has been smoked to death by you." ”

"Oh?" Lin Xiao's heart moved, he opened his eyes, and sure enough, he saw that on the water surface of the hot spring, there was indeed a small fish that turned its belly, but it didn't look like it was dead.

Shui Ling'er and Yao Tong, the two daughters, watched Lin Xiao and Du Yu arguing there, and they all smiled, thinking it was more interesting.

In this era, it is really rare for characters of this identity like Lin Xiao and Du Yu to be able to joke and ridicule each other so unscrupulously.

Especially those children of the family, they fight when they disagree, and it is even more difficult to get along.

"Hey, there's another little fish belly turning." Yao Tong suddenly exclaimed.

As he spoke, a few more small fish flipped their bellies.

All of a sudden, everyone felt that something was not quite right.

"There's something wrong with the hot spring water." Lin Xiao frowned and said, "What do you guys think?" ”

"It doesn't seem like anything special, but it's better for us to go ashore first." Yao Tong shook his head and said, "The resistance of the little fish is relatively weak, but we can't be any stronger. ”

"Is there a problem with the water quality?" Shui Ling'er was also a little surprised and asked, "Du Dashao, has a similar situation happened here before?" ”

"There shouldn't have been any similar problems, otherwise, this hot spring bath wouldn't have been opened." Du Yu shook his head and said.

The four of them climbed out of the water and wrapped themselves in bathrobes.

"Ah......" Yao Tong took two steps, and felt that his legs were weak, and he almost fell to the ground.

Du Yu helped her in time and asked with concern, "Are you okay?" ”

"All of a sudden, I felt a little dizzy, my limbs were weak, maybe there was something wrong with the water." Yao Tong replied, "Someone should have injected nerve agents in the water, but the amount was not large. ”

If the other party had injected a large amount of nerve agent in the water, the little fish might have died long ago.

Just look at the fact that they have been in the water for so long, and some small fish have died one after another, which means that the dose of poison given by the other party is not large, so they will not die on the spot.

"Lin Xiao ......" Du Yu turned around and shouted Lin Xiao, his legs were also a little weak, "We are poisoned!" ”

"It doesn't matter, it's a trivial matter, and you can't lose your life." Lin Xiao replied, then walked over with Shui Ling'er in his arms, and then put a hand on Du Yu's shoulder.

Du Yu immediately felt his spirit lifted, and the feeling of exhaustion and weakness on his body disappeared a lot.

And what surprised him even more was that a force came from Lin Xiao's hand, passed through his body, and then passed into Yao Tong's body.

Du Yu felt that he was like a bridge, carrying on the transmission of power between Lin Xiao and Yao Tong.

That is, in less than a minute, all three of them felt that their bodies had returned to normal, and the feeling of exhaustion and weakness had finally disappeared.

"Hell, what the hell is going on?" Du Yu asked a little frightened at this time.

This place was found by him, and no one thought that there would be such a problem before, which made Du Yu feel shocked.

"Maybe it's not coming for us...... Lin Xiao said thoughtfully, "Just looking at this little dose of poisoning, at most, it will make people weak and weak, unable to resist other people's means, of course, if the physique is too weak, it is possible to drown in the bath because of this." ”

"Who the hell would do that?!" Du Yu was a little shocked.
