Wasteland Code Survival

This beep...what is going on?!

Qi Lin's first reaction was that there was something wrong with the radio, but after he opened the radio's casing and checked it carefully, he did not find any problems.

There are no radio stations in the wasteland at this moment. The radio should not receive any signal. Even some messy electromagnetic waves should definitely not make such a huge buzzing sound!

Qi Lin's eyes stayed on the radio's FM frequency-FM103.7.

This frequency is not in line with any radio station in the old era. If you set the radio to this channel before the war, you will definitely hear a bunch of current noises, but at this moment, the expression on Qi Lin's face is frozen Up...

The internal communication channel of the Thunder Falcon team...it happens to be 103.7!

Although they are not using this short-wave communication, the channel coding is exactly the same.

"...Is it a coincidence?"

Qi Lin took a deep breath, and then connected the radio to the power again.

The ear-piercing buzzing sound exploded in the room like thunder. Qi Lin had an urge to cover his ears, but he abruptly listened to the buzzing sound.

The more we heard the strange color on Qi Lin's face, the more intense it became. Before he knew it, he had already accelerated the speed of the energy gathering vortex to three thousand five hundred revolutions...

After a while, Qi Lin unplugged the power.

To other people, perhaps this was just an unbearable harsh noise, but Qi Lin heard something different from this buzzing sound.

The frequency of the buzzer is very high, but it is not fixed. It has been repeating several frequencies at a high speed. If you don't listen carefully, you can't hear the changes in this frequency.

But just listening, this buzzing sound is enough to make a headache, let alone analyze it with ears.

Even Qi Lin was able to barely distinguish the change in frequency with the help of the energy gathering vortex overload force.

This is a string of Morse code, repeating three English letters all the time.

".S"

International distress signal.

Is it Cheng Yanqiu?The distress signal from Cheng Yanqiu?

Qi Lin had such a thought in his mind, but he quickly eliminated it.

The communication distance of shortwave frequency modulation is very short, and it is very easy to be intercepted and deciphered. Members of the Thunder Falcon team will never use this method to send distress signals.

And the most important point-although "SOS" is an international distress signal, the distress signal used internally by the Thunder Falcon team is another string of 32 characters that has been encrypted. Without memorizing the codebook, it is I absolutely can't read the content contained in this string of characters.

Then this distress signal...who would send it?

Is it another dispatch team?But as far as Qi Lin knows, Lei Falcon team has not sent out missions recently, even those secret missions that will not be saved, can be checked with Qi Lin's authority after joining the Shadow Force-at least he can be sure. He is the only member of the organization near the ruins of Leshan City.

And even for other dispatch teams, they would not use the three characters SOS as a distress signal.

Non-organized dispatch team?It's even more impossible. Even if they are forced to use FM radio to send them, they won't be so coincidental to "hit" the Thunder Falcon team's dedicated channel.

"Have I been exposed?"

Qi Lin is the only person around the ruins in Leshan City who knows the dedicated channel of Lei Falcon Team. Obviously, Qi Lin is the target of this distress model.

Generally speaking, the farthest receiving distance of FM broadcast is about 150 kilometers to 200 kilometers, and the signal of this buzzer is so strong, the distance must be closer.

Qi Lin opened the map and drew a circle with his location as the center and a radius of 100 kilometers on the scale. The source of this unknown distress signal should be within this circle.

As soon as the circle was drawn, Qi Lin couldn't help but frowned.

This circle...More than three-quarters of the area is within the ruins of Leshan City.

Qi Lin suddenly felt that this distress signal was probably a trap.

In an equally classic movie "Alien", the protagonist and others received a "distress signal" from an unknown source that led to a series of subsequent terrorist incidents.

Could it be a signal from the mastermind?

But... if the mastermind has found his own trail, why bother to do so, just send a born monster to encircle and suppress yourself, or simply wait for yourself to go deep into the ruins of the city and launch an attack. Anyway, your original purpose is to enter the ruins. Yes, why bother at this time?

Isn't it afraid that this "distress signal" will have the opposite effect of stunning the snake?

Qi Lin believes that with the master's IQ and calculation ability, he would never make such a move.

...

Qi Lin tried to change to another frequency, but it was silent. Only when the frequency was adjusted to FM103.7, could he hear the harsh beep, and the Morse code hidden in the beep The content has not been changed.

"Three points, three lengths, three points" corresponds exactly to the S, O, and S in the English alphabet.

However, this signal did not come from the ruins of Leshan City. As for how to determine the direction, Qi Lin thought of a way.

He found a pack of compressed dry food, then took out the food inside, leaving only the outer packaging bag.

The packaging bag is made of plastic film and aluminum foil. As we all know, aluminum foil can block electromagnetic signals and is an ideal shielding material.

Qi Lin folded the aluminum foil packaging bag slightly, then covered the antenna of the radio, leaving only a "window", and then slowly turned the simple "shielding cover" around.

He soon discovered that the signal was the strongest when the window of the shield was pointed in the direction of the ruins of the city, and when turned to other directions, the signal would be somewhat disturbed.

"Sure enough... the signal source is in the ruins..."

Qi Lin repeated the test two more times. Now, he can basically determine that the source of this "distress signal" is in the ruins of the city.

And... is the center of the ruins of the city.

Although his heart was full of ominous premonitions, Qi Lin did not shrink back, put the radio back to its original place, and he continued to move towards the interior of the ruins of the city.

From inside a dead city without any movement, an international distress signal came. It must be said that this is a very strange thing, and the distress signal is still hidden in a very harsh buzzing sound...this It seems to be hiding something... But why do you want to cover it up?
