Wang Defa has messy reddish-brown hair, and behind the heavy spectacle lenses, there are a pair of eyes full of alarm and unease.

Sha Lin originally wanted to ask more, but seeing the vigilance and hesitation in Wang Defa's eyes, he decided to go with this kid first, maybe he had something to tell him that he couldn't let Laraki hear.

Sharin pushed his wheelchair out of the cell phone repair shop, and the rain outside the shop became much lighter, and the cold wind was blowing, bringing more coolness.

When they walked into the waste electrical appliance purchase station, which was separated by only a piece of plasterboard, Shalin closed the door, looked at Wang Defa, who was rummaging through the drawers looking for tools but found nothing, and asked him strangely:

"Do you have anything to tell me alone?"

The rummaging action suddenly stopped, Wang Defa slowly turned his head to Shalin, and kept swallowing saliva, and the slightest sound came out of his throat......

But in Sharin's ears, it exploded like a bomb!

He said......

"Sir, you ......"

"Do you know you're under the surveillance of the City-State's Special Affairs Investigation Bureau?"

......

"What...... What do you mean?"

Shalin was suddenly stunned, and his mind frantically pondered the meaning of this sentence, could it be......

"No, wait, you wait a minute!"

"Wang Defa, do you really know what you're talking about now?"

He was a little dizzy for a moment, and the black memory was like the waves of the sea that had been stirred up by a hurricane.

The images of contact with the members of the city-state special affairs investigation and processing bureau came to mind at the same time, but he still didn't know when he had been under the supervision of the city-state special affairs investigation and processing bureau!

Grabbing Wang Defa by the collar, Sha Lin stared at his eyes, hoping to see a little deception and vacillation in his gaze.

Because, as memories continue to roll and emerge, Shalin seems to see the 'truth' that he has not seen before.

If what Wang Defa said is right, then ......!

He didn't dare to think about it anymore, and he didn't dare to believe that those things were true, but although Wang Defa's gaze retreated, there was no trace of deception and cunning, and his two disabled legs were hanging in the air.

He swallowed his saliva and said:

"First of all, sir, please let me down first. ”

"I'm not lying!"

"Your folding weapon has an ultra-thin nanoscale signal transmitter built into it, I carefully examined it with an electronic magnifying glass, and it looks like a scaled-down version of a waveform signal base station tower, and it's working!"

"At present, in the free city-state, the only one who can reach this ultimate level of production technology is the nanochip research department under the city-state special things investigation and processing bureau!"

"Moreover, the folding weapon also has the number of the city-state special things investigation and processing bureau left inside, indicating that the dagger gun is also produced by the city-state special things investigation and processing bureau. ”

"Sir, your every move is being monitored by CBSI-HSM, if you don't believe it, you can go and check that nanoscale process signal transmitter yourself!"

Wang Defa, who was still a little cautious, suddenly became serious when talking about his professional field, and told Shalin in an unquestionable affirmative tone that he would never make a mistake in judgment.

And the reason why he chose to tell Shalin the truth may be because of Shalin's disguised 'thoughtfulness' that he has never experienced.

It's just that in front of Wang Defa, Sha Lin at this moment still refuses this information, and keeps muttering in his mouth......

"No, it can't ......"

"It can't be!"

Suddenly, a question flashed through his mind, and he immediately refuted the disabled person who was still in his hand:

"Damn, you kid, you're absolutely mistaken!"

"I've been using this dagger for more than half a year, and I've been at sea all this time, it's really a signal transmitter, how can it still be working now, won't it run out of power?"

"And I used to take it to fight sharks in the deep sea, even if the best electronic equipment is waterproof, it will break if it is immersed in seawater for a long time!"

"You must have made a mistake, could it be that you disassembled my dagger gun and couldn't assemble it back, so you used such an excuse to lie to me?"

Sha Lin shook Wang Defa viciously, the little disabled face was red, he grabbed Sha Lin's mottled arm hard, lifted a breath of anger, and explained with great difficulty:

"Sir, you—you've just arrived in the Free City-State in the past few days, haven't you?"

"In the free city-state, there are hundreds of magnetic induction wireless charging zones in every city, and as soon as you pass through these areas, the magnetic induction coil will automatically charge your electronic devices!"

"Of course...... The electricity bill will be settled when you pay the network fee and tax!"

"Whew, whew—"

Explaining everything in a state of almost suffocation, Wang Defa fell from Sha Lin's loose hand and fell back into his wheelchair.

He gasped for breath in compensation, and Shalin had no more reason to doubt him.

Soon, another question appeared in Sharin's mind, why did Andy put a signal transmitter on himself in that situation?

Didn't he say at that time that he was afraid that he would have radiation residues on his body, so he had to send himself to a designated quarantine area?

Didn't he say it in a righteous and awe-inspiring way?

What is the function of the signal transmitter, and he has not looked for himself later, so why did he put such a 'high-level' thing on himself?

Shalin thought desperately, thinking about this whole thing that seemed to be doomed from the moment he met Andy, what was Andy's reason for doing this, and what kind of benefit could this whole thing bring to the red-haired man?

Transmitter .....

Signal ......

Signal ......

Shalin recited the word a few times, and he finally realized what the signal really meant!

Signal transmitters are not just locators, and all the information that can be transmitted in the online world is done using signals.

Audio can be transcoded into a signal, and the signal can also be decoded back into audio information!

"Audio, yes, audio!"

Thinking of this, Shalin immediately turned on his phone and searched the Internet for all news videos related to the Kappa nuclear disaster.

Immediately afterward, he saw the 'internal visit' and 'deep decryption' that he had been ignoring......

The background of the entire revealing video is black and white, the sound has been specially blurred, and the characters are all modules represented by thermal radiation, so there is no way to tell who the person who secretly photographed these things is, and there is no way to tell where they are.

However, Shalin could instantly tell that the audio was coming from the underground hospital where he had stayed and fought.

The words that had been exchanged with Keck, the impassioned brute speech of Provisional Containment Cell F-037 in Sector D, and the screams of the radiation sickness patients as they were shot by the Firewall Corporation......
