The strong desire to survive made me feel hungry - I needed to replenish my energy.

There were a lot of compressed biscuits in my backpack, which Dr. Liu and Lawyer Tang had prepared for me. I quickly put my hand in, took out a white sealed plastic bag, opened it, took out a biscuit and stuffed it into my mouth, and was about to chew and swallow it, when I suddenly remembered the scene in the dungeon of Tianyue Mansion - I almost choked to death on dry food.

Thinking of this, I immediately took out the bottle of water, took a sip, moistened my throat, and slowly chewed on the compressed biscuits - these military-style compressed biscuits didn't need to be eaten too much, a small piece was enough. I remember that he said at that time that this is a compressed dry food for individual field operations, which was developed by the Quartermaster Research Institute in the early 90s of the last century, and it took three years to successfully research, and it was specially used by the army in the field environment. Physician Liu said that this kind of military biscuits are light in weight, small in size, easy to carry and use, each gram of biscuits calories up to 5 kilocalories, high calories in addition to providing the nutrients and energy needed by the human body, but also has a significant mobilization of human body fat and refreshing anti-fatigue effect, so that people can also carry out high-intensity exercise in the case of ingesting a small amount of food, he said, in the case of no fire and no water, 5 kilograms of military individual field dry food can be used for a person for half a year of minimum life support, a small package can also make people support half a month...... I remember he had two packets in his backpack, each containing fifteen tablets, for a total of thirty tablets – enough to sustain my basic survival energy for a month, which was great!

Even if I float in this vast sea for a month, I can still maintain the most basic energy! But moisture is the biggest problem! Then there is the shark attack, there are only three packs of shark repellent, and now one pack has been used......

Let's ignore all of that for now, let's figure out a way to find a passing ship!

I felt a real feeling of fullness when I ate a compressed biscuit in my stomach, and my whole body was full of strength – it was amazing!

I was wearing a yellow life jacket, so I was able to float on the surface of the sea with little effort. I stuffed the biscuits and water into my backpack, tightened the zipper, and lay down on the water, letting my body float together with the current......

I mentally counted the treasures in my backpack and thought about which one I could use at this time. Right! Red flares! Help, color powder!

There is a box of six red light signal flares in the bag, and two packs of distress color powder, according to Dr. Liu, it should be found that the fishing boat should be found, and the red light signal flare can be used, the method used is to pull the grip, unscrew the safety cover, and then quickly pull off the pull line, downwind fire...... It will burn red flames on the surface of the sea like fireworks, and send out a distress signal. The distress color powder is a small packet of special powder, open it and put it in the seawater, it will quickly disperse, and the sea surface within a radius of several kilometers is red and bright, and the plane in the air can see it! The most amazing thing is that after the powder is dispersed, three English letters for help will be formed on the surface of the sea: SOS!

Thinking of this, I quickly opened my backpack and looked for the two small packets of powder inside, and after looking for a while, I finally found the red packet of powder!

Before using the red flare, use this treasure, hoping that this magical color powder can be seen by airplanes or satellites in the sky - then I will be saved!

I quickly tore open the packet of powder and threw it into the sea.

Sure enough, those red powders, like bloodthirsty and ferocious animals, quickly spread around when they encountered the seawater, and within a few minutes, the entire sea around me was already red, and I felt as if I was in a red ocean!

The paint, diffused to a certain extent, slowly formed three huge English letters: SOS - I can't see that effect, but I know that if you look at it from the sky, it must be clear!

That's great! That's great!

I was excited, and then stared intently at the blue sky.

The sun was getting stronger, and she was already just above me—it was noon. Time flies!

I was waiting, minute by minute.

……

It is estimated that two hours have passed, and there is still no effect, no planes have flown in the sky, not even the birds I saw just now, are gone.

I close my eyes and let them rest for a while.

Gradually, I felt my whole face be hot, and high-intensity ultraviolet rays were frying my skin all the time.

I turned around and soaked my whole face in the water, and then turned around again after a while. Although this is a little more comfortable, the bigger trouble comes, the face that has been soaked in the sea water, under the more violent and scorching afternoon sun, begins to redden, and then peels......

I couldn't help but take out the bottle of water and take a sip. The refill solution in the backpack seems to be only three small bottles, and it is estimated that it can only last for about a week or ten days.

……

The sun is slowly starting to go down, and it's approaching sea level – dusk has arrived!

There was still nothing flying in the sky, and I was very disappointed. When it gets dark, those color distress signals are basically useless.

At this time, I suddenly missed that satellite phone very much, where did I lose it? Could it still be in some corner of the backpack?

Because, I remember Lawyer Tang said that this advanced satellite phone is equipped with special equipment that can call GMDSS, the Global Maritime Distress and Safety System.

I clearly remember that Mr. Tang explained to me that GMDSS is an international distress signal that the International Maritime Organization (IMO) decided to use more than 30 years ago, replacing the "SOS" that has been used for a century, as if since the nineties of the last century, the Global Maritime Distress and Safety System (GMDSS) has been implemented, which is a brand-new search and rescue communication system established by the International Maritime Organization relying on modern radio communication technology, a modern disaster relief emergency communication system. It relies on the use of land MF, HF, VHF wireless communication and satellite communication technology to transmit distress signals and carry out search and rescue communications, which can enable the distress warning signal to be transmitted and received in a long range, provide rescue services, and be suitable for the shipwreck rescue of various ships and offshore facilities in all sea areas around the world. The GMDSS system requires that the ship must be equipped with relevant equipment, and the corresponding equipment requirements in different sea areas are also different. When the ship is in distress at sea, it can send a distress signal to a nearby ship or shore station through the VHF, MF or HF digital calling equipment and international maritime communication satellites equipped on the ship, at this time, all places on the earth can hear and quickly communicate and contact with it, and carry out emergency rescue work, even if it is a sudden accident, as long as the button is pressed, all the data about the accident and location will be automatically reported to the rescue agency. This is much faster, more accurate and more convenient than the Morse telecommunications equipment that used SOS to display 80 words a minute. Inmartelecommunications satellites can also accurately mark the location of shipwrecked vessels and guide rescue vessels to rescue them...... Many sea or desert island explorers have installed this special equipment called GMDSS!

If I had that phone, I could have sent out a distress signal right away!

I rummaged through my backpack several times, but I couldn't find the phone – I thought, the last hope was to cut open the part of my left thigh, take out the metal chip, and activate it, so that Dr. Liu and Lawyer Tang would know my location and send someone to rescue me......

Flipping into the corner, I saw a note with blurred handwriting—so soaked in sea that I couldn't tell what it was. I opened it and looked at it, and I vaguely recognized that it was the "lucky charm" with a phone number written on it and a girl's portrait left for me by Ah Ling.
