People say that tea is just two postures: floating and sinking.

There are only two postures for drinking tea: pick it up and put it down.

Life, sometimes, is like tea.

Calm when you are silent;

Indifferent when proud;

If you can afford it, you have to be able to put it down.

Now the state of Zhao Yili, Si Shuangshuang and Fang Liwen is the most appropriate to say that it is floating and sinking.

When the yacht first arrived at Duniu Island, it did not organize everyone to disembark in a unified manner, but according to the convention, in the shallow water area at the edge of the island, anchored and stationary, and put down water slides and other equipment, so that everyone began to adjust their state in the offshore water.

Then after the cruise ship docked, the young people who had completed the grouping in the cabin all ran to dive and swim.

Originally, Zhao Yili planned to just go fishing in the sea, but Guan Linlin came in a two-section swimsuit with a graceful posture, followed by a few girls who wanted to pull the three of them over to swim in the sea.

mentioned the point of going to the sea, Zhao Yili, as Si Shuangshuang's hair, did not know what her swimming foundation was, so she asked Si Shuangshuang and Fang Liwen, but they were ridiculed by the two of them, how could people who could stay in a coastal city for several years still not know how to swim, but swimming in the sea is very different from that in the swimming pool.

Although the buoyancy is much higher than that of the swimming pool, the physical exertion is much faster in the constantly moving seawater.

Zhao Yili's swim trunks are typical four-corner flat-toe swim trunks, because of long-term and large amounts of indoor and outdoor physical exercise, Zhao Yili, who has changed into swim trunks, shows everyone a wheat-colored tendon meat, and his eight-pack abs are as strong as a bodybuilder. With each step, he writhed naturally and aesthetically in front of Si Shuangshuang.

The nymphomaniac Fang Liwen couldn't help screaming, and when she came up, she reached out and touched Zhao Yili's abdominal muscles. A few exclamations said:

"Not bad, Stone, how do you exercise your body, not bad!"

For Shuangshuang, although he has been inseparable from himself in the past two days, he has not had any too intimate close contact, and now he sees Zhao Yili's sturdy and strong figure under the sun. I couldn't help but be a little bright-eyed, but I suddenly thought of something, and my face turned red in an instant. He turned his eyes and looked at the waves rushing outside the ship.

Offal.

Sea swimming.

Zhao Yili accompanied Si Shuangshuang to swim in the deep water area demarcated by the scenic spot, in fact, this was the first time the two of them had swam together, I don't know why. The action is not fast.

After the rain, the sky is as blue as washing, even the air is particularly fresh, and there are seagulls flying over the island, and the chirping seems to constantly remind everyone that this place has been far away from the city and returned to the embrace of nature.

If not immersive. You won't notice the hustle and bustle of the city and the island vacation. It's basically the same distance between two worlds.

Si Shuang shuang's swordfish rushed out, sometimes freestyle, sometimes breaststroke, tired to let the body float on the sea surface backstroke, as if since coming to Hong Kong to study, I really have the first time to relax my mood so much, empty myself, it turns out that life is so beautiful!

Zhao Yili quietly accompanied Shuangshuang, watching the sea water wet Shuangshuang's ponytail, floating on this carefree sea with the warmth and happiness of the two people.

An hour later, everyone who was finally willing to climb up to the desk to rest, while gathering together to chat, frolic, and replenish drinking water, it was also a quiet and harmonious scene.

Swimming is not all there is to the sea, but diving is more attractive than swimming.

Based on the diving foundation of these three people, Guan Linlin took these three people and pulled Captain Levi, who originally wanted to make up for sleep in the cabin, into battle, and asked him to train the three of them to carry out literacy on the relevant skills and precautions of diving.

Levi's smiled wryly and explained the history of the development of diving to the three of them in a concise manner:

As early as 2,800 years ago, during the heyday of Mesopota culture, the army of the Azriya Empire used sheepskin bags to attack enemy troops from the water, which may be the ancestor of diving.

The predecessor of today's professional diving is the mechanical diving invented by the British Golmon Besy 160 years ago, that is, helmet diving.

This type of diving first appeared in Japan in 1854. In 1924, the "mask submersible", which used glass as diving goggles and pumps to draw air from the surface, was the predecessor of scuba diving equipment. In this year, the Japanese used a mask submersible to dive 70 meters to the bottom of the Mediterranean Sea and successfully retrieved the gold nuggets from the sunken ship Yasaka, which shocked the world.

During the Second World War, a special military "air cover submersible" was developed, using a closed-circulation device with air cylinders. At the end of World War II, France developed an open "air submersible", which became very popular in Europe and the United States around 1945.

In recent years, due to the progress of diving equipment, diving sports have flourished, and more and more people have devoted themselves to diving and liking diving sports.

In addition to being an experienced captain, Levi's biggest personal hobby is diving.

Levi continued:

Necessary learning for sea diving: including how to use snorkels and regulators, how to rest on the surface, how to deal with emergencies, etc. Preparation before entering the water is very important.

Check whether the equipment is functioning properly by yourself, and check each other again.

Position to enter the water: Vertical diving - the water depth should be more than 1.5 meters, with both feet open in front and back, holding the mask with one hand and the air tank strap with the other. Entering the water with your back to sit - sit on the boat facing inwards and enter the water with your back on your back.

Frontal seated entry into the water - for beginners. Sideways into the water - then float on the dinghy and roll into the water. Dive: B.C. (Buoyancy Moderator) method - when using a buoyancy regulator, with a counterweight belt, the head and feet of the dive. Do not use B.C-head under foot. Ascent: Control the rising speed to less than 18 meters per minute, simply put, do not exceed the rising speed of the air bubbles you exhale; Don't stop breathing; Look up at the water as you ascend. You can stretch out your right hand to specify the direction, pay attention to your back, and slowly rotate your body.

Therefore, in order to give everyone a standard demonstration of action. Levi was even more active in putting on the diving equipment of Guan Linlin, Zhao Yili, Si Shuangshuang and Fang Liwen one by one, and then chose a diving area with a medium depth of 80% light transmittance and began to practice.

It is worth mentioning the vignette, however, because the lighting conditions here are very good, and the water temperature has reached an idealized level of about 28 degrees, so the diving suits of several beauties did not choose which one to protect the whole body, but was led by Guan Linlin. I chose a two-section wetsuit that leans towards the Japanese visual kei, and the advantage of this wetsuit is that in addition to the very good cold protection effect, it can also bring out the beauty of the female body. Seeing this choice of the beauties, although Levi was not surprised by Guan Linlin, he still shook his head again with a wry smile.

Zhao Yili's eyes were sharp, and he saw that the coach was this expression. I was stunned for a moment. For a while, I didn't understand why the coach had this expression.

It was his first time diving, and Si Shuangshuang was even more nervous, after all, when he had no experience and dived for the first time, the subtle feeling of isolation was even more memorable.

Although he grabbed Zhao Yili's left hand tightly, Si Shuangshuang's heart settled down a lot, but the expression on his face still looked a little nervous, and he slowly followed Zhao Yili into the cool and clear water. The sunlight is refracted by the water into countless stars, constantly twinkling and shining in front of the eyes.

In the process of diving. Colorful corals and colorful fish, affectionately snuggled up to him, and swam around the people in a circle, Si Shuangshuang suddenly felt happily that the original nervous mood had long since disappeared since seeing the corals and schools of fish.

Zhao Yili also feels that he is now in a wonderful and novel world, enjoying the colorful and diverse underwater creatures; As a string of bubbles, happily floating through my ears, through the exploration of a new world, I was surprised to find myself easily fanning my flippers, floating freely in the water, truly experiencing the wonder, romance, freedom and happiness of the water world.

Only then did everyone remember what Levi had just explained:

The benefits of diving are not only the great enjoyment of the strange world in the water, but more importantly, it can improve and improve the cardiopulmonary function of the human body. According to scientific evidence, the balanced pressure of water on the human body helps blood circulation, and long-term oxygen inhalation under water can effectively kill cancer cells and inhibit the spread of cancer cells.

After reaching a given underwater depth, the buoyancy device does not sink, but is suspended above the seabed, in the seawater.

According to Levi's request, in addition to enjoying the alternative beauty in the sea, everyone also began to check their diving personal equipment one by one.

Today, everyone is wearing light-loaded equipment, which is different from the heavy-duty professional equipment that is more suitable for scientific research work. There are masks (and light helmets), air hoses, communication cables, telephones, emergency tanks, wetsuits, waist lead, boots and fins, etc.

As night fell, the partners on the shore had already fixed their tents according to the groups in the cabin in advance, and on Duniu Island, in order to protect the environment and prevent fires, bonfires and other activities were to be carried out at designated locations.

Fortunately, everyone's tent site is not far from this place.

The moon is bright and the stars are sparse, the breeze is blowing, and Zhao Yili and others, who reluctantly ended the first unforgettable diving experience area, have changed into casual clothes and sat around the bonfire and chatted.

What is rare is that it is not just Guan Linlin and Zhao Yili who are camping on the island today.

Usually there are not many tourists camping on the island, many people are going back and forth on the same day, only on weekends, the number of people on the island will increase, after all, there are more than 230 islands off the coast of Hong Kong, and most of them are suitable for playing.

And Yanjing at this time.

But the moon was dark and the wind was high.

It is said that on such a special weekend night, many people will choose to have a small gathering with friends, although at this time there is no big week in the country to implement the two-day system, but people who commute on time, in the early 90s, entertainment projects are also pitiful.

The time has long passed the time to get off work, Ma Yan has already gotten off work, he is alone, thinking that it is okay to go home early, so he went to the canteen of the institute to have dinner, and after packing up the materials in his hand and filing, he said hello to the director Gao Dayong and walked slowly to the outside of the office.

At this moment, the old black telephone on Gao Dayong's desk rang loudly.

Gao Dayong immediately picked up the phone, while Ma Yan slowed down his pace of leaving from work, only to hear Gao Dayong's deep voice coming intermittently:

"Got it, I'll immediately bring someone to fully assist, okay, pay attention to safety."

At this time, Ma Yan, who had complicated undercover experience, was immediately able to guess what was going on, since there was something, although he was an outsider who came from temporary training, and he was also a policewoman, he had enough reasons to stay out of the matter, but the pride in his bones made Ma Yan unable to pretend not to know, so he said to Gao Dayong:

"Gaosuo, what's going on?"

"An hour ago, in Jianguomen, there was a serious foreign-related shooting case, and intelligence showed that the suspect is now in our district, and the above asked us to cooperate with the armed police and comrades in the army to arrest him, but we must absolutely block the news.

To be honest, the danger of this operation is too great, as a cadre who has come on a temporary post, pony you"

"Gaosuo, don't say it, it's not the first time for me to face a complicated situation, and I've encountered something worse, let's not waste time, let's act immediately!"

Gao Dayong had no choice but to decisively issue an order, with 8 public security officers including Ma Yan, driving two police cars, to the meeting place.

No one could have expected that the result of this operation would be a farewell to 5 young and lovely public security officers! (To be continued.) )
