"That's all there is to it."

Nodding, Lin Cheng actually planned to start from those cracks at the beginning, but the appearance of this metal door was really a bit abrupt, he really wanted to find out the specific situation of this door, since he couldn't open this door now, then he could only retreat.

Walking to a crack with the most serious cracks, Lin Cheng took the Soul Breaking Sword and stabbed it a few times, and the slight resistance from the sword body made him understand that this wall was completely different from the cement wall structure around the passages outside, even if it was cracked, but because its material was already extremely strong, he stabbed it many times with the Soul Breaking Sword to open this gap a few points.

More and more interesting, Lin Cheng was not anxious, he took the Soul Breaking Sword and patiently slashed in front of this gap, and finally, after consuming half an hour of his time, this gap was finally stabbed out by him with the Soul Breaking Sword A hole that could barely accommodate one person to enter and exit.

Looking back at the ruins in the passage behind him, seeing that there was still no movement over there after so long, Lin Cheng felt a little relieved, nodded to Bai Ling and Peter, and bent down and got into the hole.

"Step on ......"

The thickness of this wall was much wider than he had imagined, and after getting through the hole with some difficulty, Lin Cheng landed lightly on the ground inside, waved his hand to signal Bai Ling and them not to rush in first, and took out a flashlight and turned it on and quickly glanced at it.

This is a room of about 100 square meters like an office, the walls around the room are placed with more than a dozen metal tables and chairs, and there are some documents scattered on the ground, the position of these tables and chairs looks a little messy, I think it should be because the previous earthquake was shaken out of the original position, and because of the long time, the tables and chairs have formed a little rust, at first glance it gives people a strong sense of age.

The paper documents on the ground have been slightly yellowed, and the handwriting on them Lin Cheng took a few looks, and found that most of the handwriting on them was actually written in Eagle language, only some of the notes were in Doom language, and under Lin Cheng's careful study, he found that most of these documents were inconsequential things, such as who was late today, and who made a mistake today.

Quickly flipped through this office, and found that there was nothing here except for those tables, chairs, benches, and documents with little reference value, Lin Cheng frowned slightly, looked up and looked around, always feeling that something was not quite right in this room, but he couldn't tell where these things were coming from.

"How's it going, what's the catch?"

Seeing Lin Cheng standing in the middle of the house frowning and silent, Bai Ling, who was staying outside, couldn't help but ask him.

"Not yet."

Shaking his head, Lin Cheng searched around the wall of the house again with some reluctance, and Bai Ling and Peter saw that there was no danger inside and Lin Cheng did not stop it, so they also got through the opening in the wall, leaving only Coke to be on guard outside.

"Is such a thick metal door just to protect such an ordinary office?"

After the three of them searched the house again and again but still found nothing, Lin Cheng leaned in front of a metal table, holding a cigarette and thinking to himself.

Bai Ling and Peter, after looking at the few documents on the table, had already regarded this place as a high-level office in the underground mine, in their words, this room must have been more than this before, but it may have been removed from all the important documents and items in the room when they were evacuated, leaving only a room full of heavy metal tables and chairs, and useless documents that would not reveal any important information.

For Bai Ling and Peter's speculation, Lin Cheng was noncommittal, although this explanation sounded reasonable, but he was well-informed, but he faintly felt that this office could never be so simple, the metal door he had just carefully observed from the inside, and found that the materials and workmanship of the gate were somewhat familiar, and after thinking about it, he finally remembered that this was simply a special blast door for the arsenal used to prevent heavy weapons attacks!

The use of such a blast-proof door in a high-rise office room is unreasonable for this matter.

Because of this, he did not leave without finding any clues, but carefully recalled in his mind what he had just seen.

Finding that Lin Cheng seemed to be thinking about something, Bai Ling and Peter didn't bother him, the two of them walked around the room lightly, moving the metal tables and chairs piled up on the side of the wall from time to time, wanting to see if they could find other clues while Lin Cheng was thinking.

Just when they moved the last table, the metal table, which should not have any pressure under the joint efforts of the two of them, looked extremely heavy, and after moving it a few times, with a loud "bang", the metal table slipped directly from the hands of the two and smashed heavily on the ground!

"What's wrong?"

With this loud sound like thunder on the ground, Lin Cheng, who was contemplating and thinking, hurriedly raised his head, and found that Peter and Bai Ling were looking at the metal table next to them with a confused face at this time, and behind the metal table, a black wire connected to the metal table and the wall behind it was tightly stretched in the middle, and the end of the wire connected to the wall was a little worn, but it was not broken, and it was obvious that the material of this wire was not ordinary.

"Here...... How can there be a wire? ”

After standing for a moment, Peter finally reacted, stepped forward and pulled the black wire, and said with a puzzled expression.

Hearing this, Bai Ling pursed his lips indifferently, and replied in a not very fluent language: "Even if this underground mine is a little old, it's normal to have electricity or something, right?" ”

"You, you...... You can even speak the language of Doom?! ”

Hearing the words of doom popping out of Bai Ling's mouth, Peter on the side was suddenly frightened, he had always thought that only Lin Cheng could speak the words of doom, so when communicating with Lin Cheng, he always wanted to say what to say, but he didn't expect that this very young Huaguo woman would also speak the words of doom, and for a while he quickly recalled whether he had inadvertently said anything unfavorable to the other party before.

"......Shh

Looking at Peter's startled virtue, Bai Ling glanced at him with disdain, and turned his head to look at Lin Cheng, "What do you think?" ”

"What do I think?"

Hearing this, Lin Cheng unconsciously turned a cigarette in his hand a few times, then walked to the wire and tugged at it, feeling that his hand was tight, and the material was full of toughness, so he said: "I'm thinking, if this office has come to an end, then where did this wire come from?" Also, you've been talking about how old this underground mine is, but why haven't you realized that we've been here for so long that we don't even know where the doors of the mine are opening? ”
