After the automatic sensor door is opened, there are only three elevators in the empty room, and there are security corridors on the left and right, which is really simple and straightforward.

"Hey, this base is not something we designed at the time, and the whole base structure can be said to be simple and crude. Zero explained as he pressed the elevator button.

Bite~

The door opened immediately, and what made the two of them shine was the elevator space, at least the size of 3 normal elevators, and it should be no problem to stuff 50 people at a time.

Actually, this design is too power-intensive, maybe people at the time thought that we would come and go often, but in fact, except for the flow of people who routinely explore in the morning and evening, no one used it the rest of the time, so the base director only opened one elevator, and the other two morning and evening rush hours were opened. ''

''Tsk, it seems that the old man was rightly worried. Nameless shook his head helplessly.

The three of them entered the elevator, but it felt a little empty in such a large space, and there were only 5 buttons inside the elevator, which were ground, combat, work, scientific research, and management. This design is really simple and crude, so that the combatants can enter the battle in the first place, it doesn't take long to climb the stairs, the work area is used as a buffer zone, and the scientific research management lasts, this design is also very good.

Zero pressed the button on the battle floor: ''As you can see, very rough zoning, but it's not just a minus 1 floor, minus 2 floor. The combat area is five or six meters underground, and then includes 3 floors, the elevator only goes to the first floor of the combat area, and the remaining two can only take the stairs, the work area is the largest, including a total of 5 floors, and two floors in the scientific research area, but our scientific research force is actually only one floor enabled, and the last layer is the management, not the office you imagine, in fact, it is more of a general control center, and I have heard others say that it is not enough to enter it.

''Didi,,,''Suddenly, a small electronic alarm sounded in the elevator.

Zero hurriedly took out a card and slapped it to the card area: "Hey, patronizing the introduction, I forgot to swipe the card, there is an electronic card hanging on the key of your dormitory, that is your ID card, every time you take the elevator, you have to brush it once, of course, when there are many people, someone must brush it, and you must remember to brush it when you sit alone, mainly for idle people not to enter the scientific research management." Also, your card hasn't been activated yet, there are integrated service centers on each floor, I'll take you there. ''

Box box ~ box box ~

After a short time, the elevator arrived at the combat area, and the fixed fortifications were greeted by two half-lying sentries on duty seats, waving to three people, with obvious numerical codes on the chests of their clothes, CN.0026 and CN.8276X.

"Let's go, I don't know who is on duty today, your dormitory is on the second floor, and you have to go down the stairs." ''

''Wait, zero, that X is dead more than twenty times?' ''9527 asked halfway.

"Hey, no, the base will code you uniformly, but it won't write out the number of times you have died, you haven't seen this yet, this is also a code, the same as your 9527, but there is an extra X, the specific reason is unknown, but the size of the potential clone has expanded from 4 digits to 5 digits at once, so, there is still a lot of hope for the future. ''

''Heh, that's about that later.'' Nameless rose to the top of his waist, and the three of them continued, making their way to the stairwell.

As soon as they entered the stairwell, the two of them were shocked by the huge electronic door, the thickness of which felt like it could be blocked even if a nuclear explosion occurred.

This is part of the base defense system, if the zombie breaks through the surface defense, the electronic door will automatically lock, the soldiers in the combat area rely on the fixed fortifications to block, if the pressure on the first layer is too large, the electronic door will be opened, the zombie part of the drainage to the second layer, disperse the pressure, and so on.

''Already thinking about the capture of the base?'' ''

After all, the last bastion of mankind, it is not too careful, all we can do is to thank the people before us and defend this place. Zero waved his hand and continued to walk down with the two of them, walking about 4 flights of stairs before the battle area on the second floor slowly appeared.
