This Omega is Sweet and Wild

Chapter 61

Xiao Yiheng first told Youyou how Archimedes discovered the principle of buoyancy while taking a bath, and this principle is actually the same as the essence of Cao Chong's conception.

Youyou had never heard of Archimedes, but Cao Chong said that she still knew! "Cao Chong's Appreciation of Elephants" is a compulsory content in elementary school textbooks, but the Chinese class focuses on Cao Chong's intelligence and wisdom, while Xiao Yiheng talks about the physical principles involved.

Youyou didn't know until today that Cao Chong started to study physics at such a young age, the ancient friends are too pitiful

"In short, the buoyancy force on an object is equal to its own gravity." Xiao Yiheng dipped his fingers in the water and drew a simple stick figure on the shore. The stick figure was a stick figure in a swimming skirt, and it looked like a pomelo.

He drew a pool, drew a stickman pomelo, and then drew a vertical upward arrow on the stickman's belly.

And this is the force analysis diagram of pomelo pomelo swimming.

Youyou half understood: "Brother Xiao, what do you mean, when I was swimming, an invisible hook lifted me up?"

Xiao Yiheng: "...It's not a hook, it's buoyancy."

"Does the elephant also have this hook?"

"..." Xiao Yiheng retreated in defeat, "Yes."

"Then why the hook didn't lift the elephant up, but it lifted me up."

"Because elephants are denser than water."

"Density? What is density?"

Xiao Yiheng explained how the ten-year-old boy knew density and buoyancy. The more you listened, the more confused you became.

Youyou is tired and doesn't want to fight anymore.

"Brother Xiao, I really don't understand what you're talking about." Youyou hugged the neck of the flamingo pontoon and said aggrievedly, "I can't see that hook either."

Xiao Yiheng tried his best to explain: "The hook—I mean buoyancy—is not visible to the naked eye, it is something you can feel."

"But I can't feel it!"

Li Cheng listened for about ten minutes, watching Xiao Yiheng drawing force analysis diagrams and explaining density formulas. He was busy for most of the day, but the progress was negative.Looking at pomelo pomelo again, the two big eyes are covered with two groups of tears, which is more pitiful than the little day lily in the field.

After all, Youyou is only ten years old, so multiplication and division are not easy.Xiao Yiheng wanted Youyou to understand the force analysis diagram that even Li Cheng couldn't understand.

Li Cheng could not stand hearing the smoke coming from his brain.He jumped into the water, walked quickly to Xiao Yiheng, and asked Alpha to let the two brothers and sisters go, and stop reciting those annoying formulas: "There are so many messy things in swimming, do I have to do it every time I stroke the water?" Do you calculate the buoyancy formula in your heart? Swimming is an instinct, you have talked so much, do you know how to swim?"

Xiao Yiheng was unexpectedly silent for a long time.

Li Cheng:! ! !

Li Cheng was shocked: "woc, you don't really know how to swim, do you?"

He thought that Xiao Yiheng was the king, but he didn't expect that Xiao Yiheng was not even as good as bronze.

Xiao Yiheng has a plausible saying: "A good gourmet may not be able to cook; a good film critic may not be able to make movies..."

"—But a good swimming coach can definitely swim!" Li Cheng interrupted his sophistry, "Okay, Xiao Yiheng, just stand next to Youyou honestly! My brother Li doesn't believe this evil anymore, isn't it just Swimming, I will definitely teach you two today!"

So Li Cheng changed from teaching one person to teaching two people.

No, not people, but two pigs.

No, pigs are so cute, and they are born to swim, how could he use these two stupid elm heads to insult the cute little pigs?

Li Cheng once thought that a top student like Xiao Yiheng must be proficient in everything. Apart from being able to draw and solve problems, he should be good at all kinds of sports as a matter of course. How could Xiao Yiheng not be good at something as simple as swimming? will it?

Xiao Yiheng smiled wryly: "Remind me, there is no causal relationship between 'I am a top student' and 'I can swim'."

Li Cheng bared her little tiger teeth ferociously: "Then what constitutes a causal relationship? Can there be a causal relationship between 'you can't learn to swim' and 'I'm going to be stupid to death by you'?"

"..."

Li Cheng put his hands on his hips, looked at the two landlubbers in front of him, and issued orders with a serious face.

"I'll count one, two, three." Li Cheng said, "Dive down together and hold your breath. Pay attention, don't squat straight down, bend your legs slightly, bend over and bury your head in the water. You must relax your body, Especially relax your waist and abdomen, and feel that something is holding your lower body up to the surface of the water. As long as your buttocks float up, your legs will naturally float up!"

"That's not 'something'," Xiao Yiheng corrected, "It's 'buoyancy'."

"That's not 'something'," Youyou imitated, "It's 'little hook'."

Li Cheng said firmly: "It doesn't matter what it is, in short, you have to hold your breath underwater for a while... Forget it, hold your breath for 30 seconds first."

"30 seconds is so long." Youyou said nervously, "What if I choke on water?"

Li Cheng comforted her: "Don't worry, my brother is here to watch over you, and my eyes will never leave you. And I have been trained as a lifeguard. If you really choke on water, my brother will give you artificial respiration."

Upon hearing "artificial respiration", the little adult Youyou seemed to cover his mouth, and said in disgust, "Hey, forget it!"

Li Cheng: "..." Is there any reason for an older brother to be disliked by his younger sister?

Under the deterrence of Li Cheng's iron face, the two beginner swimmers stood up slowly, held their breath, and lowered their heads into the water.

Li Cheng counted for them, one, two, three...

I don't know if it's because Xiao Yiheng was with Youyou this time, under the water, the little girl's body gradually relaxed, her waist gradually floated up, and then her buttocks, legs, and feet went up one by one, and her whole body was supported by the water Get up!

Her limbs were spread wide, her eyes were tightly closed under the water, and she was dragged up to the surface by the invisible "little hook".

It wasn't until the oxygen in her lungs disappeared that she broke through and popped out of the water with a bang, her whole face was flushed with excitement.

"Brother, did you see that!" Youyou danced, "I learned how to swim!"

Li Cheng tapped her on the head: "You just learned to float, you haven't learned to swim yet. Well, you go to the shore to rest, and come down later to continue practicing."

After practicing for so long, Youyou was already tired, and after receiving her brother's pardon, she immediately jumped ashore.There are vending machines on the shore, and you can put coins in the pomelo and exchange for a bottle of cool happy lemon tea.

When Youyou was relaxing freely, Li Cheng frowned and stared at Xiao Yiheng's shadow under the water, his expression became more serious.

One minute has passed, and Xiao Yiheng's figure is still under the water, neither floating nor relaxing, like a heavy stone.

Is his lung capacity so strong that it is not exhausted now?

Li Cheng was worried that Xiao Yiheng was showing off his power, so he hurried to his side and stretched out his hand to pull him out of the water.

Unexpectedly, before Li Cheng stretched out his hand, his waist tightened—Xiao Yiheng, who was underwater, actually hugged his waist, and dragged him into the water with all his strength!

"Fuck, you dare to sneak attack! Gulu Gulu Gulu..." Li Cheng was caught off guard, and all the unspoken obscenities turned into a series of bubbles.

The shallow water area is only 1.2 meters, and when Li Cheng stood up straight, the water just overflowed his waist.Because of professional training, after entering the water, Li Cheng did not panic, but immediately opened his eyes, turned around as fast as he could, and kicked Xiao Yiheng's shoulder—this bastard dared to sneak attack him in the water Donghai Little Dragon King, who gave him courage?

If you don't give Xiao Yiheng a little color today, then Brother Li might as well take his surname!

Unexpectedly, facing Li Cheng's kick, Xiao Yiheng didn't dodge or dodge, but went up to him directly, holding Li Cheng's ankle with his big hand, and dragged the omega towards him domineeringly.

Shui Liu became Alpha's most powerful assistant, Li Cheng's body lightened, and he was actually dragged to Xiao Yiheng.

Li Cheng's eyes widened in surprise, her lips opened unconsciously, and the bright red tip of her tongue flashed between the two rows of white teeth.

——The next second, Xiao Yiheng kissed her.

The four lips joined together, the air in the mouth was taken away and sent back lingeringly.

The underwater lights and shadows are mixed, and the clear and mysterious blue surrounds the two teenagers. As the water waves rise and fall again and again, those chaotic lights are divided into countless fragments.

Li Cheng stared blankly at Alpha who was close at hand, between the messy light and the blue water waves, Xiao Yiheng's handsome face was a little distorted.

Xiao Yiheng's eyelashes closed lightly, and the water gently brushed the corners of his eyes and brows.He is no longer a cold iceberg, he has already been melted by Li Cheng.

No one knows that in this seemingly calm swimming pool, there is a passionate kiss hidden under the surface of the water.

……

Youyou was sitting on the shore with her chin resting, with a straw of happy lemon tea in her mouth, looking suspiciously at the two people in the pool.

"Brother Xiao, what's wrong with my brother?" She asked ignorantly.

Just now, brother Xiao was practicing holding his breath underwater, and brother suddenly dived into the water, and then saw the waves churning, and then gradually calmed down—then, the two of them got out of the water at the same time!

Li Cheng's face was flushed, and his mouth was broken. Xiao Yiheng half-supported and half-armed him, and sent him to rest on the bench by the bank.The blond hair was wet with water, and it hung wetly on his forehead, making him look like a cat that just took a bath.

Youyou circled around in concern, she took Xiao Yiheng's hand, and asked again: "What's wrong with my brother?"

Hearing her sister's question, Li Cheng turned around in embarrassment, covered her red ears with a towel.

In the end, it was Xiao Yiheng who answered her question.

"I just choked on water." Xiao Yiheng touched her head and said solemnly, "Your brother gave me artificial respiration underwater, so he is very tired now and needs to take a good rest."

Li Cheng: "..."

What a god tm artificial respiration!

I don't know if it was because Xiao Yiheng's expression was too serious, but Yuyou was really fooled by such a wrong answer.She obediently sat aside, quietly waiting for her brother to rest.

Li Cheng hid her face under the towel, and it took a long time to suppress the heat on her face.

Damn, are all alphas like this guy who gets angry regardless of time and place?She actually attacked him in the swimming pool, causing him to feel hot from the toes to the earlobe.

Because he went into the water without taking off his T-shirt just now, the white T-shirt on Xiao Yiheng's body was completely wetted by the water, and it almost became transparent, so that he wore it on his body in a way that seemed to be exposed but not exposed, revealing his body line faintly , It is more eye-catching than stripping completely.

Li Cheng sat on the bank for a while, and found that several people were secretly looking at Xiao Yiheng when they passed by, and some people took out their mobile phones to take a sneak shot, but they were scared away by Li Cheng's eyes!

Li Cheng asked in a muffled voice: "Xiao Yiheng, how long are you going to wear wet clothes?"

Xiao Yiheng was very "obedient", grabbed the collar with both hands, and took off the soaked clothes directly.Before Li Cheng was ready mentally, Alpha's strong and thin body broke into his sight.

Different from Li Cheng's honey-colored skin, Xiao Yiheng's skin is much whiter because he stays indoors all year round, but it's not the kind of skinny and thin.He is a standard person who looks thin when he is dressed, and he is fleshy when he takes off his clothes. His muscles are thinly covered on his skeleton, supporting his straight shoulders and thin waist.

Li Cheng looked away shyly, but immediately looked back.

He forced himself to be tough, and deliberately looked up and down Xiao Yiheng several times with that kind of picky gaze, and finally a few words floated out from the corner of his mouth: "...All right, you barely passed the test."

"Reluctantly?" Xiao Yiheng raised his eyebrows, "Brother Li thinks that I am not good enough, please give me some advice."

While talking, he put his hand on his arm: "Is it because the biceps are not developed enough?"

Next, his hand moved to his chest: "Is the chest muscle not strong enough?"

The hand slid down the chest again, and finally, it fell on the waist and abdomen: "It's still the abdominal muscles..."

"—Stop!" Li Cheng immediately jumped up from the bench, covered Youyou's eyes, and scolded him with a blushing face, "There is still a little girl here, what kind of hooligan are you playing?!"

However, the little girl tried her best to break away her brother's hand, looked out from between Li Cheng's fingers, and yelled repeatedly: "Brother, brother, let me have the abs of a handsome guy."

Li Chengyu asked earnestly: "Youyou, how can there be such a handsome guy with big abs here, did you drink too much water when you were swimming just now, did you have hallucinations?"

……

After Li Cheng's persistent teaching all afternoon, Youyou finally learned to swim!

Li Cheng taught her the most basic basic breaststroke. Youyou was very clumsy with her hands and feet. She swam ten meters long enough for Huang Yelun to swim 50 meters.

However, Li Cheng was quite satisfied. When Youyou worked hard in the swimming pool with her own efforts, the big stone in Li Cheng's heart finally let go.

See, water is nothing to be afraid of.See, she can beat it.

As soon as youyou learned how to swim, she became more courageous. She took her brother's hand and said that she wanted to play on the ten-meter slide.

The large slide is the most eye-catching amusement facility in the entire indoor swimming pool, where all tourists gather to enjoy the weightless thrill of going down the river.

"Then... okay." Li Cheng hesitated for a moment, and allowed her sister's little willfulness.

Youyou was very happy, hugged the inflatable flamingo's neck, bounced towards the slide, and ran away without a trace.

"Li Cheng, what about me." Xiao Yiheng, who was also staying in the shallow water area, leaned over, trying to imitate Youyou's tone, "I also want to play on the slide."

"You can't." Li Cheng straightened his face, "Youyou have already learned how to swim, you idiot haven't learned yet. That slide is dangerous, you don't know how to swim, if you plunge into it when you rush out of the slide What if you can’t float in the water?”

"It's okay." Xiao Yiheng pointed to the promotional board next to him, "Look, there is a tandem slide there, two people can skate together."

Li Cheng looked in the direction of his finger, and when he saw the photo on the publicity board, his face blushed instantly.

There are a lot of photos posted on the board, in groups of two, all of them are sweet couples.With the assistance of the staff, the young lovers hugged each other, lying on the slide, and rushed down the water.

There is also a beating red heart next to the promotional photo, saying "Enjoy the feeling of extreme weightlessness with the one you love!"

There is just a small problem, the single slide is free, but the double slide is an extra charge, the price is really not cheap.

Li Cheng's little abacus was knocking again: "No, no, I want to find excitement, why don't I practice the [-]-meter platform for two? Ten meters, double, rapid weightlessness, swimming pool, the four key words are all there. Why should I spend money here to seek guilt?"

"..." Xiao Yiheng asked quietly, "Li Cheng, have you only heard the word 'romantic' before?"
