Huo Chi pressed his ear to the cold hatch, closed his eyes, and listened carefully. Beneath the ground, there were no human voices or footsteps, only a slight buzz.

He listened for a while, and felt that there should be no problem, so he raised his head and said, "There is no movement down there." ”

"Alright, everyone get their weapons ready, let's open the hatch. Fu Ze took out the pistol and put on the silencer.

Others, like Fu Ze, attached silencers to pistols and assault rifles. However, because the sound attenuation effect of the assault rifle was far inferior to that of the pistol, the five people still held the pistol in their hands first.

Xiao Jian was standing next to the button that opened the hatch, he got Fu Ze's instruction, and directly reached out and pressed the white button.

With a "rub" sound, the mechanism of the hatch opened again. Fu Ze stood on the edge of the hatch and nodded at everyone, and everyone became nervous.

Seeing that everyone was ready, Fu Ze took a deep breath and carefully opened the hatch.

Beneath the open hatch came a slightly moist air, very different from the dry night breeze on the ground, which made people feel warm and comfortable.

Fu Ze looked down, and under the hatch was a metal escalator, the ladder style was simple but it looked very strong. The ladder led down to a narrow, slightly darkened corridor that seemed to end with an iron door.

Fu Ze frowned slightly, he had a little understanding of the structure of the White Eagle Bunker, under the bunker was generally a basement with two to four floors, and the plane area was only slightly larger than the building upstairs.

The basement of the bunker is not complicated because of its purpose as a store of supplies and habitation, but there is only a corridor under the hatch that leads to the distance. Apparently, this place has been transformed.

It seems that there is something wrong with this place. How did the people here renovate the basement under the nose of the White Eagle, and why didn't the White Eagle find a problem here?

Fu Ze raised his head and gestured at Huo Chi, Huo Chi understood, and immediately waved his arms lightly, and two bumblebees emerged from his sleeves one after the other.

The bumblebee flew straight to the hatch, and soon, the two small monsters approached the metal door at the end of the corridor, and the two bumblebees flew around the iron door twice, conveying the message of safety to Huo Chi.

Huo Chi immediately nodded to everyone, and when Fu Ze saw this, he knew that it was safe for the time being, so he walked down first.

Huo Chi followed behind Fu Ze and carefully stepped his foot on the metal escalator, but he still made a slight noise.

It's not a good thing to have too good ears, and you don't know how loud your voice really is when you sneak into an action like this. Huo Chi sighed, hurriedly lowered his steps a little lighter, and then came to the corridor with Fu Ze.

The others saw that there was nothing wrong with the two of them, and they also walked down. At this time, Fu Ze and Huo Chi were already approaching the metal door at the end of the corridor.

The metal door is still similar in style to a certain hatch, except that, unlike the one on the ground, it is locked with a valve.

Fu Ze looked at the round valve on the hatch and hurriedly beckoned to Xiao Jian.

Sapper Xiao Jian walked over, carefully inspected the hatch and nodded that there was no problem, and Fu Ze carefully rotated the valve.

This valve is obviously used a lot, so it rotates very smoothly and does not make too much noise.

Fu Ze didn't know what was on the other side of the door, although Huo Chi listened carefully and felt that there was nothing wrong with the door. But to be on the safe side, he still spins very slowly, basically taking a minute to make a turn.

Those minutes or two seemed like a century to the rest of the Snow Leopards. Quietly above the hallway, only the sound of everyone's breathing could be heard.

Fu Ze found that he could no longer turn the valve, which meant that the gate had been unlocked. He released his hand from the valve and placed it on the doorknob, and with a little force, the heavy iron door opened.

Two bumblebees immediately flew in through the crack in the door, and soon, Huo Chi nodded his head to indicate safety.

Fu Ze hurriedly opened the iron door completely, and everyone carefully looked at it and found that it was another narrow corridor.

However, at the end of the corridor, there is actually a metal door. However, this metal door is no longer a sealed hatch, but a password door with an electronic lock.

Seeing this, Huo Chi's brows furrowed. I'm afraid of this kind of door, and I don't know the password and want to open the password door, but it's very difficult.

"What should I do?" Huo Chi felt a little tricky.

Fu Ze turned his head to look at Xiao Jian and said, "Can you unlock this combination lock?"

"This type of lock is common to White Eagle, and it generally only has a four-digit password. Xiao Jian said: "It's just that if this kind of password is entered more than six times, an alarm will sound." ”

"That means we only have five chances?" Fu Ze asked.

"Theoretically, that's true, but I expected that to happen, so I've brought some of this today to help us eliminate some of the wrong numbers. Xiao Jian took out a small bottle and a small brush from his waist bag.

Huo Chi noticed that Xiao Jian's small bottle was some white powder, and Huo Chi, who had watched spy war movies and criminal investigation films before, instantly understood what it was. It seems that Xiao Jian really came prepared, and actually brought such a thing.

Fu Ze nodded slightly, and Xiao Jian immediately walked towards the metal door, while the others followed closely.

Coming to the iron door, Xiao Jian carefully checked the password door, he felt consistent with his previous judgment, and then opened the bottle, dipped it in powder with a small brush, and gently swept it on the black button.

Xiao Jian brushed carefully, and the white powder on the brush was quickly absorbed by some keys.

The buttons are black, so the white powder is particularly eye-catching. Huo Chi noticed that the 1248 buttons on the keys adsorbed the most powder, and it seems that these buttons should be pressed frequently.

"Hopefully, they don't have the habit of changing their passwords too often. Xiao Jian said in a low voice: "Captain, look, how can these numbers be combined?"

Fu Ze glanced at Xiao Jian, knowing what four numbers are, it is not easy to decipher the password, there are twenty-four combinations of four fixed numbers, and it is not complicated to try them one by one. The problem is that they only have five trial-and-error chances, and beyond that number, the combination lock will call the police.

"There are only five chances, do you have any impression of these four numbers?" Fu Ze asked in a low voice.

Huo Chi immediately shook his head, he had been in this world for too short a time to know any information related to these four numbers at all.

"Try 1284?" Qin Lang said, "I remember that the time of the second large-scale attack of monsters lasted from December to August of the following year. ”

"Is it August 4th?" Fu Ze asked, "I don't remember the specific time it ended." ”

"It seems that the official time is on the fourth of August, and I remember it as follows. Qin Lang said.

"Try it. Fu Ze thought for a while and nodded at Xiao Jian, Xiao Jian immediately pressed the button carefully, but unfortunately, in everyone's expectations, the back door did not open after this password flashed twice.
