"So when swimming, we ask our bodies to be as parallel to the surface as possible so that we get the most buoyancy from the sea, but obviously it's not enough for us to do that. For example, floating, when we keep our back down and lie still in the water, then the gravity may be the same as the buoyancy, in this case we can ensure that the mouth and nose are always out of the water, of course, this is also a basic way to save oneself when a person is in distress in the sea. ”

"But when we're swimming, our backs are facing the sky, which means we're lying on our stomachs in the water, which is the most common thing we do when we swim. In this case, our human body will be much less buoyant, so we need to repeatedly stroke up and down with both hands to create an upward force. With this force, combined with the buoyancy of the water, we can basically keep us from sinking. ”

"But you're going to ask, I just moved my legs. That's right, when a person is swimming, his legs kick backwards, which creates a forward force that allows him to swim forward. That's the basics of how we swim, get it? ”

Brook winked wide playfully at Riley, expecting her response. Riley saw that Xiaoxi not only had a clear mind, good eloquence, and a very clear expression, but also had some humor and cuteness, and she had to admire this little sister in her heart, she felt that she was really lucky to have made this friend today.

"Creek, I basically get it, you're awesome! I like you so much. Riley pinched Brook's face and replied playfully.

"yes, actually, that's what I think." Creek gritted her teeth at Riley and pinched one of her faces.

Not to be outdone, Riley quickly scratched Xiaoxi's smooth waist with both hands, and said while scratching: "Yes, I haven't seen such a shameless sister, and I really want to go to heaven to give you a ladder." ”

"Ah...... Don't ......" Creek suddenly screams and runs away, the fear of being tickled is every girl's weakness.

However, Riley did not intend to let her go easily, and continued to entangle after the stream, facing such a cute girl of the same age, Riley was so playful that she completely forgot her awe of the sea.

"I was wrong, sister! I'm not great. Brook turned back in horror to prevent Riley from chasing after her, and exclaimed, "Ah...... I was wrong. ”

Riley proudly chased after this little sister and continued to punish her, she thought that she must take the initiative first and let the other party obediently be her good sister, otherwise this extremely smart girl will definitely bully herself every day in time.

Unexpectedly, Xiaoxi suddenly splashed a handful of water at her in a hurry, and Riley faced Xiaoxi's sudden counterattack, she was suddenly frightened, and took two steps back in a panic and begged for mercy: "Xiaoxi, don't mess around, I'm afraid of water." ”

Riley just looked aggressive, but she immediately felt empty, the momentum of the two suddenly came to a 180-degree reversal, Xiaoxi observed the cringe and hesitation on Riley's face, she immediately made an arrogant expression to Riley with confidence: "Hmph, who is just domineering, indifferent to my begging for mercy, for my such a lovely sister, you have no pity at all, this is simply unforgivable." ”

Riley looked at the serious expression on Xiaoxi's face, she knew that this girl would definitely not let her go, so she waited for an opportunity to prepare to escape. Unexpectedly, Xiaoxi had already noticed all this, and she first took a splash of water in her hands and sprinkled it at Riley.

"Ah......h

"Ah...... I was wrong! Good sister, I was wrong, stop it. Riley saw that she couldn't just suffer in vain, so she quickly lowered her posture and begged for mercy, and at the same time she was very unconvinced, and secretly made up her mind that she would take revenge if she had the opportunity.

Xiaoxi can be regarded as having basically mastered Riley's temperament, and she judged at a glance that Riley was just admitting defeat on the surface, so she continued to pour water on her while shouting, "What did you say?" I can't hear it, louder! ”

Xiaoxi shouted and laughed evilly.

"I was wrong! Stop it! Riley shouted angrily.

"Oh! Are you wrong? The creek finally stopped, "It seems that I also said that I was wrong, you say, which of us is wrong?" ”

After Xiaoxi finished speaking, she looked at Riley's aggrieved and embarrassed appearance, but she still couldn't help but smile at her.

Riley almost choked up when she saw this: "You bully people." ”

To make matters worse, Riley also spotted Carter not far behind the creek, and he was also looking at him with a wicked smile on his face, and the annoyed Riley suddenly picked up a handful of seawater and threw it at the creek.

However, due to Riley's natural unfamiliarity with water, her clumsy movements caused the water she picked up to lose its proper direction when it floated in the air, and fell into the sea halfway through, without hitting the stream at all.

The angry bird simply kept pushing the sea into the stream with the palm of her hand, but her crooked action really worked, and the splash flew straight to the stream.

"Ouch! No, I'm afraid of water. Xiaoxi obviously realized that she had really scared Riley, so she played with Riley's little temperament, and she turned around and begged for mercy while running behind her: "Sister, don't, stop." ”

Riley looked at her underwhelming look and yelled, "Die! ”

"Okay, I was wrong, sister, you still have to learn to swim!" Xiaoxi was heartless and heartless, but Riley was angry, and Riley yelled in annoyance: "Sister is not studying!" You bring it to my sister! ”

"Haha......" Xiaoxi saw that Riley was really angry, and she laughed and plunged into the water, dodging Riley's innocuous splash.

Yang Bin also saw all this, and he quickly swam over to stop Xiaoxi and prevent her from bullying Riley again.

Riley looked at Carter with complaining eyes and said dissatisfiedly, "Didn't you tell me to swim?" ”

Carter smiled and said, "I think the brook will teach you well, and she has at least succeeded in getting you to overcome your fear of the sea." You see you dare to come into the water now, you didn't dare to do that before. ”

Carter said as he walked towards Riley, who listened to Carter's words and suddenly realized that she had indeed overcome her fear of water a little bit, at least she dared to walk around and play in the water over her waist. Riley's heart was relieved of this thought, and she was full of confidence at this time, and suddenly smiled and splashed a handful of water at Carter, who was walking towards her.

Carter saw that Riley finally forgot about her chagrin just now, and laughed happily, he didn't dodge, just let her splash water, he was glad that Riley could have so much fun in the water.

Yang Bin also came behind Carter at this time, he looked around for the trace of the creek, but by the time he found the creek, it was too late, and she was quickly sneaking towards Riley from behind.

"Ahh Riley, who was playing at this time, suddenly screamed, and her legs suddenly felt like something was firmly clamped from behind, and finally struggled desperately a few times to finally break free.

Poor Riley was smiling like a flower, but she was instantly frightened and jumped a few steps into Carter's arms. What's even more exaggerated is that Riley hugged Carter's neck tightly, and couldn't wait to jump on Carter's shoulders, her legs firmly clamped Carter's stomach, her face turned pale, and she looked left and right and said to Carter in horror: "Carter, hurry up and go ashore, there are water monsters." ”

Carter was a little dazzled by the two sexy goblins in front of Riley in front of him, and he really couldn't stand these two playful girls like children. Carter had already spotted the creek that was quietly approaching Riley from behind, after all, the water here was too clear for people to hide, and the creek was just taking advantage of Riley's carelessness to seize the opportunity to trick her. This can't be blamed on Riley, who still retains a certain awe of the boundless water.

"Carter, run!" Riley's legs tightly wrapped around Carter's waist, and seeing Carter's indifference, she urged loudly again.

"Hey, calm down, baby." Carter was holding Riley's ass with both hands, "Look behind you. ”

Carter stared at Riley tightly and comforted her, Riley saw the evil smile on his face, she still thought Carter didn't know the seriousness of the situation, and looked back in horror, but saw Jiang Xiaoxi behind her smiling and bending over while teasing her wet bangs.

"Haha! I bet it's the first time you've seen such a beautiful water monster. ”

Riley's face was still terrified, she was bent on escaping back to the shore, but she couldn't understand why everyone was indifferent, and when she heard Xiaoxi say that it was the first time she had seen such a beautiful water monster, she was still at a loss, and she didn't understand why Xiaoxi said this.

Riley's mind went blank and suddenly she felt that something was wrong, "No, water monster...... Beautiful water monster, Xiaoxi is saying that she is a beautiful water monster...... Oh, my God! Could this be a prank on the creek! ”

Riley's deep fear of the sea is fully exposed by this prank of the creek. She looked at Yang Bin again, and his face was also with a helpless smile at this time, as well as Carter and Xiaoxi, who were all looking at her. Riley finally realizes that this is a prank, and that it is the abominable brook that has just played tricks on herself underwater.

Riley's face was hot at this time, and she was full of foreign appearance in front of everyone, she simply turned away and didn't want to pay attention to anyone.

"Hey, baby!" Carter looked up at Riley, her eyes fixed on the sea in the distance, not saying a word.

Riley felt a little sad, she really couldn't overcome her fear of water, everyone didn't do their best to help her, and made such a big joke. However, Riley quickly calmed down, and perhaps in the perception of others, they may not really understand their fear of water. In their eyes, such a joke is completely normal, and the special thing is that her fear and strangeness of water far exceed their expectations.

Riley thought like this, naturally she didn't really get angry with Xiaoxi, and finally she broke free from Carter's arms and stood in the sea, looked back at Xiaoxi and Yang Bin, and then bravely held her breath and slowly squatted down to the bottom of the sea, letting the sea water slowly submerge her mouth and nose until her hair floated on the water.
