"Door?" Looking at the door where the two of them came in with puzzled and puzzled eyes, Yan Mo and Mo Yin noticed the ingenious design on the door.

Opening this door from the outside requires the magnetic card in the hands of Yan Mo and Mo Yin to open it, and behind the door there is a different design structure.

Behind the door, a combination lock with a "0-9" ten numeric keys plus a "back" and "confirm" buttons, and one side of the password lock, more than ten centimeters away from the password lock, is a place to swipe the magnetic card, the magnetic card is not deep in the door, only the device for swiping the card is outside.

Mo Yin and Yan Mo came to the door together, hesitantly fiddling with the magnetic card.

"I don't know if this is a trap, but according to common sense, people inside use password locks to open the door lock from the inside, and people from the outside world can't open the door lock without a magnetic card, this arrangement is also very careful, but it can't be determined what will be opened by swiping the magnetic card for the second time."

In the end, Yan Mo still tried to swipe the magnetic card once, and tried to see if he could start it with just one swipe of the magnetic card, and after swiping the magnetic card, there was no sound in the room, and the breathing of the fainted guard could be heard.

Then, Mo Yin swiped the magnetic card in his hand again, and there was still no movement in the guard room, which made the two of them wonder if a card reader was a decoration, or if the two of them ignored something!

"Let's see if they have magnetic cards on them!" Yan Mo immediately thought of finding the magnetic card on the two guards who went out, so the two guards who stayed in the guard room could find the magnetic card, then the two people who stayed in the guard room must also be carrying the magnetic card.

Sure enough, two magnetic cards of the same style were found from the pockets of the two, and Yan Mo swiped the third magnetic card from the card reader, "It's weird!" Is it really necessary to swipe four magnetic cards in a row to turn it on!? ”

Yan Mo muttered, and the fourth magnetic card inadvertently wiped from the card reader.

"Click" There was a slight tremor where the two of them were standing, Yan Mo and Mo Yin just wanted to retreat, and the floor where the two were standing sank for a short time. Suddenly, the floor on which the two of them had stepped began to rise.

The floor gradually rose to a height of half a meter, and the steel bars that supported them below were welded one by one, closely connected to the floor, after Yan Mo and Mo Xian jumped off the floor, they began to look under the floor through the exposed slits, and only a small range under the floor could be seen, as for the deeper places, it could definitely be called a finger that could not be seen.

When the floor was one meter high, Yan Mo and Mo Yin watched as the space below the floor gradually lit up, and there was a passage more than four meters deep. On one side of the passage, a chain of ropes resembles a rope ladder that extends to the lower end.

"I'll go down and take a look first, and I'll hand it over to you, pay attention to vigilance!" Yan Mo moved his body to the passage that flowed out after the floor rose, and hovered his hands and feet on the iron chain rope ladder, Yan Mo slowly fell, and after standing firm, he gently flicked the mask on his face, and walked towards the only bright road ahead.

Ground floor. Yan Mo touched the cold wall through his clothes, the road with light stretched all the way, and after walking for a few minutes, small forks began to appear, and it was only at this time that Mo noticed that there was a rotating monitoring device at every fork. Mo had obviously entered the monitoring area of one of the monitoring devices.

"How's that going to be? Yan Mo, who was hesitant, turned the direction of his head, and the mask was also facing to the side, and after a few seconds, Yan Mo walked forward casually. Out of the monitoring range.

After passing the monitoring range of this monitoring device, there was a small difficulty on the road ahead of Yan Mo, and the door at the end of the trail that Yan Mo entered was locked. And it was locked from the inside, and Yan Mo couldn't find a single keyhole on the door in front of him, so Yan Mo had to go back the same way, and once again passed through the monitoring range of the monitoring device, and returned to the forked intersection.

At the fork in the road, Yan Mo first marked a small symbol in the corner of the road he walked, such a symbol is a unique symbol of the Mo family, and only a certain type of disciple of the Mo family can understand it, so Yan Mo used three long and one short lines on the corner of the wall to depict the symbol, and then walked towards the middle passage of the fork in the road.

Meandering, on the middle passage of the forked road, there were already five monitoring devices on Yan Mo's head, and the passage was extending forward, and in the passage where the small door appeared, Yan Mo probed the situation inside the door, and it was all some boxes for storing supplies.

The further back he went, the door was tightly fastened with a wide chain lock, Yan Mo used a dagger to cut off the door lock and enter the house, and the supplies packed in the box were also transformed from military supplies to daily supplies, and there were still a lot of meat, beans, cold and fresh vegetables and so on stored in several rooms.

When Yan Mo realized that he had walked far away, Yan Mo had already walked out of the fork in the road for fifteen minutes, even if he had delayed a lot of time to check the materials in the door, but Yan Mo still made a preliminary calculation, the path that Yan Mo walked through at least ran through the underground of this town, just such a huge project, it could not be completed without three or five years, Yan Mo began to guess about other forks in the road, are other roads also like the forks in the road where he is, with supplies?

When Yan Mo walked back to the forked intersection again, Yan Mo's plan to investigate again was disturbed by Mo Yin's urgent call, and Yan Mo had to hurriedly return to the guard room.

"Mo, the people who have contacted them are constantly asking why they haven't been at work yet, and I think the person who called them is the fifth person who should be in the guard room! Be cautious when you come back, you might run into that guard on the way back! ”

After Mo Yin left, Mo Yin first put the two guards in the house in a lying position, and the blood stains sprayed in the house were simply cleaned up a little, and the unconscious guards gave him a good time after Yan Mo went down a few minutes, until a hoarse voice came out of the small speaker in the room just now, "It's time for work, I'm waiting for you in the old place, come quickly!" ”

There was no response to the successive urgings, and the guard who summoned the message began to curse angrily with some irritability, and Mo Yin had to quickly inform Yan Mo of this matter, so that Yan Mo would pay attention to the safety of the return trip.

"Quick! Get out of here! Yan Mo came up from the passage along the iron cable safely and soundly, and he pretended to go forward before returning, and knocked out a lot of monitoring devices while walking, and Yan Mo also deliberately chose the supply road he had walked.

Withdrawing from the guard room, the four of them evacuated back according to the old method, and the four of them, who couldn't take care of a lot, directly spread their steps and ran back, anyway, the monitoring of the east gate had been removed, and the four of them didn't take a while to get out of the enemy's line of sight, and after running far away, they crawled again and retreated slowly to the foot of the mountain.
