"Oh my god!" Song Ziyu bounced away like a cat stepping on its tail, looking at the girl as if facing a formidable enemy.

As for Ma Xiaolong and An Tong, they were stunned on the spot.

"Get out of the way!" A watermelon knife struck, and Xu Yingnan took action boldly, taking the head of the girl with short hair.

However!

An incredible scene appeared! ??

The watermelon knife was slashed out and wiped across the girl's neck.

Xu Yingnan even kept his hands and used only the blade of the knife.

However, Xu Yingnan cut the air.

Cut the air...

The light ripples and folds then return to their original state.

The girl stood there, looking at everyone with her clear eyes.

"Who are you? Why is there no identification mark?" the girl asked again in a crisp voice.

"Are you a human or a ghost?" Xu Yingnan felt like facing a formidable enemy.

I tried my best to slash, but it failed.

The girl didn't say anything, but the whole space suddenly seemed to come alive. Several holes were opened on the ceiling above her head, and countless muzzle bullets stuck out from the holes.

"Intruder found, activate the secondary defense strategy... start it?" As the girl spoke, she turned to look at Song Ziyu.

"Start it?" the girl asked again.

Song Ziyu suddenly realized that this girl seemed to be asking herself!

"Are you...asking me?" Song Ziyu looked at the girl and asked in surprise.

"Of course I am asking you, the respected secondary authority administrator." the girl replied.

"Then don't shoot. If you have anything to say, let's talk it over." Song Ziyu waved his hands quickly and said.

"Is this a valid order issued within the authority?" the girl asked.

Song Ziyu rolled his eyes and said, "Of course! This is an order."

"As you wish!" the girl said.

Then, smallpox

All the muzzles on the board were retracted almost at the same time and disappeared behind the alloy curtain.

"So, who are you?" Song Ziyu calmed down and then asked cautiously.

There was no emotion on the girl's face regarding this question.

"My name is Han Meimei, the internal affairs manager of the 013 Dungeon. I specialize in serving you, the respected second-level authority manager."

Of course Song Ziyu knew that his "secondary administrator authority" was stolen, but the...internal affairs administrator in front of him was really weird.

For some reason, the girl gave herself an unreal feeling.

"You are not a human! What are you?" Xu Yingnan looked at Han Meimei and asked.

Just now, Xu Yingnan felt weird when he took action. No matter how bad the watermelon knife was, it would never be able to hit the air. At this time, while Song Ziyu and Han Meimei were talking, Xu Yingnan reached out and touched Han Meimei. Unexpectedly, he caught an empty hole.

This Han Meimei does not exist!

This discovery was undoubtedly horrifying, and everyone looked at Han Meimei as if they had seen a ghost.

Among everyone present, except Song Ziyu, Han Meimei has surpassed everyone's cognitive scope.

"Are you a projection?" Song Ziyu asked.

Han Meimei nodded and said: "I am an artificial intelligence AI. The image in front of you is my concrete projection. If you don't like it, I can change it. So, do you like a mature one? Or a sexy one?"

As she spoke, Han Meimei showed her charm.

Song Ziyu quickly waved his hands and said: "It looks good like this now."

Now that it was clear that Han Meimei in front of her was just artificial intelligence, Song Ziyu felt slightly relaxed.

"What is this place used for?" Song Zi

Yu asked.

"Dungeon 013 is a permanent shelter that exists to cope with major disasters." Han Meimei replied.

Cataclysm!

This was not the first time Song Ziyu heard this term.

"This underground city is numbered thirteen. It has a capacity of 500 people when it was initially built. It can fully meet the self-sufficiency in a closed state." Han Meimei continued to introduce.

"The underground city is divided into six floors. The first and second floors below are ordinary office areas, the third floor below is the agricultural area, the fourth floor is the management area, and the sixth floor is the underground evacuation passage."

Hearing this, Song Ziyu asked: "Where is the negative fifth floor?"

"Minus five...minus five...minus negative..." Han Meimei suddenly got stuck and kept repeating one sentence.

Is this a crash?

"Are you okay?" Song Ziyu asked softly.

At this moment, Song Ziyu raised his voice in his heart, fearing that the artificial intelligence would go down and shoot everyone with bullets.

Fortunately, after a brief lag, Han Meimei restarted and returned, and then said: "The data on the negative fifth floor was damaged, and I cannot read the information... However, according to the data left behind, the negative fifth floor is very dangerous... You guys

It’s best not to go.”

Song Ziyu didn't care about what was on the fifth floor, he only cared about how to get out.

"Is there an exit from this shelter?" Song Ziyu asked quickly.

"The shelter should have a backup safety exit, but you need to go to the management area to get a map to know the specific location." Han Meimei said.

"Then what are you waiting for? Let's go to the management area...you will lead the way." Song Ziyu was overjoyed.

"plz follow me!"

So under the guidance of Han Meimei, Song Ziyu quickly found the elevator door hidden behind a large green plant.

Song Ziyu and his party passed the elevator and went down to

The management area on the negative fourth floor.

"You should be careful, there are many mutants on the negative fourth floor." Han Meimei suddenly warned.

Tang Jian checked the bone blade in his hand and then stood ready.

Everyone was gearing up, and everyone knew that the battle was about to begin again.

"Han Meimei, can you destroy them?" Song Ziyu asked.

Han Meimei shook her head and said: "These mutants are the legal authority holders of the shelter. According to my program settings, I am not qualified to kill them."

But Han Meimei continued: "Although I can't kill them with my own hands, you can... I can provide you with the location of the mutants through the base's blind-angle surveillance, and then inform you in advance."

Song Ziyu was overjoyed when he heard this. Such words were like opening a map plug-in!

really!

With the help of Han Meimei, the zombies in the management area were eliminated very easily. They almost always gave advance warning, set up an ambush in advance, and then made a sneak attack... Soon the team arrived at the core area of ​​the management area.

Unlike the previous floors, there are many strange-looking machines on the negative four floors.

Song Ziyu observed carefully and was almost certain that these strange mechanical equipment all showed the characteristics of high-tech civilization.

The alien civilization that built this shelter in front of you is very advanced!

Even higher than the Blue Star Civilization that exists on our own!

This makes Song Ziyu somewhat unacceptable...

But the facts are right in front of us.

Moreover, what makes Song Ziyu feel even more incredible is that the craftsmanship of the two civilizations is completely the same as seen from these machines.

What is the relationship between this collapsed world and the Blue Star civilized world?

Song Ziyu couldn't understand it, but he was also deeply afraid.
Chapter completed!
