In the end of the ice age, I hoarded tens of billions of supplies

Zhang Yi will always pay attention to changes in the external situation, because it will affect whether his life is safe in the future.

Perhaps all of this is just his unfounded worry, and there will be no powerful organization to attack here.

But he must be prepared for all precautions.

"Xinxin, come and see your new equipment!"

Zhang Yi stood up from the sofa and wanted to take Yang Xinxin to the supercomputer.

Yang Xinxin sat in the wheelchair, Zhang Yi asked the others to stay, and pushed her to the control room by himself.

After pushing the door and entering, Yang Xinxin looked at the console in front of him, with a bright light in his eyes.

The scene layout in the control room makes people feel like they are in the universe.

Wang Siming is a person who pursues luxury, so he installed OLED screens even on the floor of the control room.

The blue light is like a river of stars in the universe, and the buttons of various colors on the huge console in front of him are neatly arranged.

"In the future, the network information security here will be entrusted to you!"

Zhang Yi patted her on the shoulder.

But her gaze involuntarily fell on her legs that could not walk.

A genius with an extremely developed mind who contracted polio and was paralyzed from the lower body - there is hardly a better candidate than her.

Yang Xinxin nodded and rolled the wheelchair to the console.

Zhang Yi used his highest authority to grant her secondary operation authority, preventing her from modifying the core content of the system.

Just to allow her to maintain network security.

Yang Xinxin didn't say anything, walked over, put Bai Nen's hands on the console, and started to dance like a pianist playing the piano.

Blocks of black and blue panels appeared on the big screen, and the codes slid past quickly.

Zhang Yi didn't understand either, but stood beside her with great interest.

In less than 10 minutes, Yang Xinxin checked the network of the entire shelter.

"How about it, is there a loophole in the network?"

Zhang Yi asked.

Yang Xinxin looked at him and said, "This Galaxy Light system was the top personal network system ten years ago, and its performance is very powerful."

"Even now, it can crush the absolute majority of network systems in the world. Its artificial intelligence is very powerful, and theoretically there is no security loophole."

Speaking of this, her tone suddenly changed: "However, top hackers can create loopholes."

"In the past two weeks, the system has suffered thousands of cyber attacks. If it is not discovered in time, the entire network system will be paralyzed in a month at most."

Zhang Yi stared.

His guess was right!

After Lu Fengda's incident, he and this shelter inevitably attracted the attention of interested people.

And people who can do this kind of thing are definitely not ordinary.

He asked Yang Xinxin: "Can you fix the vulnerability and prevent these attacks?"

The corner of Yang Xinxin's mouth curled up in a contemptuous arc.

"Brother Zhang Yi, don't forget what my major is!"

As the world's top hacker, she is best at network security, and she is especially good at attacking others.

Although the other party also has Internet masters, they are obviously far behind her.

"It's very easy to fix the vulnerability. And I will re-create an encrypted network for you to use, don't use the previous router again."

"Otherwise, it would be pretty easy to hack through a wireless network."

Zhang Yi said: "You figure it out!"

It didn't take too long for Yang Xinxin to operate, so she raised her head with a smile and said to Zhang Yi: "Brother, I'm done!"

On her bright little face, the words "quickly praise me" are written.

Zhang Yi smiled slightly and patted her head: "Xinxin, you are awesome!"

Yang Xinxin's touch on Zhang Yi was very helpful.

But she still said: "It's just simple maintenance, it's not difficult."

A sly gleam flashed in her eyes, and she seemed a little excited.

"Next, I'll see who wants to hack into the network here."

She stuck out her pink tongue and licked her lips, "It would be so interesting if I could hack into the other party's network in turn!"

As a top hacker, it is her instinct to constantly challenge more difficult tasks.

After thinking for a moment, Zhang Yi asked, "How sure are you? Or, if you fail, what are the risks?"

Zhang Yi was also very curious about the organization that was spying on him secretly.

He has no intention of actively attacking, but it would be great if he could learn some information about the opponent.

Yang Xinxin said: "It's hard to say how confident it is. After all, we haven't had a formal fight yet, so we don't know the opponent's strength. From the current point of view, their cyber attack on the shelter is not strong."

"But brother, don't worry, even if I can't attack their network, at least I can hide my whereabouts, so I can still do it without being discovered by them."

Zhang Yi nodded in satisfaction.

"Okay, if that's the case, go ahead and do it!"

Anyway, others have already done the first grade of junior high school, so he naturally wants to pay back.

While the two were talking, suddenly Zhou Ke'er's panicked voice came from outside.

"Zhang Yi, it's not good! It's weird... a monster!"

Zhang Yi and Yang Xinxin looked at each other.

"That cat really likes you, and they all chased you."

Zhang Yi smiled.

Yang Xinxin tilted her head: "Probably the only human being it trusts is me! Because I can't trust me, that's why it followed me."

Zhang Yi had already discovered that the cat demon had followed him.

He also has plans to subdue this cat demon and use it as a weapon in his hands.

However, right now it is indeed necessary to subdue it as soon as possible.

Otherwise, many people would die on the other side of the river.

"Let's go, let me go and have a look!"

Zhang Yi pushed Yang Xinxin's wheelchair out of the control room.

Zhou Ke'er's face turned pale, and she hurriedly hugged Zhang Yi's arm for comfort.

"Zhang Yi... there's a big monster outside! It's been meowing into the room outside the window."

"Keran said he had to call Xinxin over. It followed Xinxin."

Zhang Yi said: "Don't be afraid, it is Xinxin's friend. Let's go and have a look!"

Zhang Yi pushed Yang Xinxin to the living room.

Outside the window, there are two huge eyes in the night, staring into the room like red lanterns.

The cat demon Huahua howled from time to time, but she didn't seem to have any malicious intentions. Instead, she seemed to be urging others to feed it.

After seeing Yang Xinxin, it sat down quietly in the snow.

If you ignore its hair like steel nails, this is a big cat.

Yang Mi hid behind the table, staring at it with two eyes exposed.

Lu Keran was a little better. After all, he knew that it was a stray cat that Yang Xinxin had fed, so he wasn't that scared, but he also kept a sufficient distance from the glass window.
