AA dragged the zombie into the operating room first, while 9527 and Nameless walked around the hidden hole, observing the surrounding situation.

9527 looked through the small notches with automatic turrets, while Nameless was interested in the abandoned fortifications.

Touching the thick reinforced concrete bunker, I can't help but wonder, if it is a secret research institute as AA said, this level of fixed defense is conspicuous enough, as for building a building outside? Although it is only a small flat building, it is already very conspicuous when it is built, after all, on the satellite map, the effect of building one layer is the same as covering dozens of layers, for what secret research institute, it is really a failure, or rather, it is an ordinary research institution? You don't need this level of fortification.

Just thinking about it, suddenly the alarm bell sounded, it was the old-fashioned class bell, but the sound was far louder than it, and even a few broken small lights kept flashing red, and in the bunker where he was, some machinery and equipment were also buzzing, although they had long been damaged, but they were obviously activated.

As soon as he got out of the bunker, he saw AA running past him and rushing straight into a bunker, and after a few seconds, everything calmed down.

9527 scratched his head and came out from the other side, and he knew by looking at that embarrassed but polite smile that he had done a good thing.

''Blame me, blame me, I forgot to say this, I only remembered it when I entered the house, but I didn't care if I thought it would be done in three or four minutes. AA played a round field, but 9527 also knew that he had suddenly committed two, and followed the muzzle of the cannon all the way to the cave, and found the password door, and there was a light on it, and it was still four digits on it, and suddenly the bad taste rushed to his heart, and the ghost accidentally entered the four numbers of 9527, and the alarm was triggered.

I've tried this cipher door a few times, and it's hard to guess even though there are only four of them, and every time it triggers an alarm, the first time it attracts a crowd of corpses, and it took nearly a month to clean it up. ''

But don't worry this time, there are no zombies nearby, pay attention when you sleep at night, at most it will attract some sporadic zombies.

AA continued to explain everything here, leading the two of them towards the electronic door, which was no different from the one in the movie, and the shimmering keyboard next to it proved that it was still functional.

"I've searched all the houses in the neighborhood, and there is no information about the password, so it's impossible to open the door, and it's ...... in my life."

Drip~~~~

At that moment, time stood still

Both AA and 9527 stared at Nameless with wide eyes, the voice they knew was the sound of entering a password, and Nameless stared at them with wide eyes......

This ,,, is not ,,,, ,,,, me, no,,,,

At this time, Nameless was also shocked, but his fingers were indeed pressed on the keyboard.

This,,I feel like I've been here.,I know the password.,Talking to myself.,Nameless pressed three more keys.。

The expected alarm did not sound, but there seemed to be no movement, no movement at all.

I was stunned for a few seconds, only to hear a click,,,, door opened.
