– Now you have a screen, your thoughts will first be reflected, they will go back into your brain, you will hear yourself, and then you will decide which ones to release. You can release exactly what you want, that is, you can lie. That's it, time is running out, find a similar radio-isolated shelter and do a couple of experiments on yourself to get used to it and understand how it works.

– How do they hear my thoughts?

– All in the form of brain bio-signals, they can only be decoded. For example, such as truth, lies, anxiety, euphoria, and the like. Dialogue is by mutual initiation only; in cases where the receiver knows you well and has had numerous non-conflict communication sessions, then your chip will let it through. You will recognize it, it is provided, you can feel it, you just need to get the hang of it. There is, of course, a way around all blocking, directly, but you need a code for that.

– Where, who has it?

– Let's get another charge. That's enough, it might arouse suspicion.

They repeated the procedure with the wires, the doctor explained further.

– I don't know exactly, it's written in the secret department of the coders, kept by the person in charge of controlling the coding and encryption service.

– Where are they?

– No one knows specifically, this is where all the original codes come from, rumor has it – it's called "The Sphere".

Ruthra took a deep breath and began to exhale slowly, shaking his head.

– There is the center itself, which does not exist for everyone, and there are a lot of organizations, which either are or are not. ZKR, "Sphere", what else?

– Go on, everybody, forget about me.

Ruthra couldn't help but ask another question.

– How does ISU-A2 read minds?

– It doesn't read, it sees, as if on a network. The computer-brain interface is like an extension of one in the other. You draw everything from its base, and it draws from yours.

– Why does she have free access to me?

– "Not now," the medic said and pointed to the top of Ruthra's head, then put his index finger to his lips, giving the silence sign, pushing him in the shoulder toward the door.

Ruthra went to the exit, stepping out into the hallway.

– You've been gone a long time, did something happen? – he heard Isa.

"Well, bitch, you're following me," Ruthra thought and immediately realized how the lockdown worked, his own voice sounding in his head. "It's okay," he thought and directed his thoughts to her.

– I'm happy for you," the computer replied.

– I'm going out, goodbye.

– Exit via the stairs or the pod.

– You have a service here. Can I get a regular cab? – Ruthra asked jokingly. – Is there an elevator? I don't want to take the stairs for half an hour.

– Yes, to the left of the capsule hatch.

– Didn't notice. Just like everyone else here. Ready, here I come.

– Did you give a request to get out?

– No. What's the request?

– It's not like we're in a backyard, you have to give notice, get permission.

– No one told me.

– Go to the ops guy you talked to, he'll authorize it.

Ruthra made his way to the CUO and scanned his eye, the door opened. An operative with two assistants sat at a console with numerous glowing indicators, with numerous monitors in front and to the sides. The Operative was not the one who had been in charge of the alert headquarters: it was more pleasant for Ruthra, he didn't want to ask something from a man who had just been court-martialed.

– Here. I was warned," the operative said and held out a small device that looked like a magnifying glass.

Ruthra picked up the object, began to examine it.
