"What's wrong with this door?" Wang Kaixuan looked at the iron door in confusion, but he couldn't see a reason.
To say that he is good at charging into battle, but the precise matter of finding traces is really not what he is good at.
After staring at the iron gate for a while and failing to get any results, he complained: "You said there are only three of us here. Is it interesting for you to play riddles?"
However, Chen Ziyan saw some clues and understood what Hu Bayi wanted to express. He looked at Wang Kaixuan and said seriously: "Fat man, look carefully. The gap in the door is caused from the outside."
It was only then that Chen Ziyan discovered that the edge of the gap was sunken from the outside inward, which meant that something was attacking the iron door from the outside, causing such a gap.
"Is it caused from outside?" Wang Kaixuan was a little confused at first, but he soon understood, and his face became more solemn: "This gap was actually caused from outside!"
He is just not good at this aspect, but it does not mean that he does not understand it at all. At this time, he is not sure what is going on when he gets the prompt.
It doesn't matter which side of the iron door the gap is caused by, but if you add the device that blocks the door, there is something special about it.
At the same time, it further illustrates that it was humans, not beasts, who destroyed the iron gate in the first place. At least the leader was definitely a living human being.
If it was really the work of wild beasts, how could they deliberately move the equipment to cover it up after destroying the iron gate?
If a beast can have such intelligence, it can no longer be called a beast.
As soon as Hu Ba saw that the two people understood what he meant, he said to them: "From the existing clues, it is inferred that someone should have been here many years ago. When they left here, they deliberately blocked the entrance with that device.
”
Wang Kaixuan was surprised and asked: "Someone came here many years ago? Where did they come in?"
He believed what Hu Bayi said, but he couldn't figure out where the other party got here.
My family knows their own affairs, and it is somewhat of a coincidence that they were able to enter this fortress.
And being able to set foot on the third floor, whose entrance has long been destroyed, is even more due to the cave of the prairie giant otter.
But now they tell him that someone has been one step ahead of them. How can he believe it so easily?
Hu Bayi was also puzzled, but still said: "Although there is no other evidence, the marks on the door in front of us are enough to prove that someone did come here before us."
"This is strange." Wang Kaixuan had no way to refute this.
Although there is no way to explain this matter, the fact is already before his eyes, so he cannot help but not believe it.
Just as everyone was about to go downstairs, a flash of light suddenly flashed in Chen Ziyan's mind, he looked at the two of them and said:
"Is it possible that the cave we came down to was dug by someone who directed the prairie land otters?"
In fact, after seeing the situation here, Chen Ziyan vaguely felt that something was wrong.
However, he couldn't figure out what was wrong for a while, but just now it suddenly occurred to him that there were no traces of prairie land otters living here.
Whether it was the outside of the steel building or the inside of the building, they had already checked it, but they could not find any trace of the prairie land otter.
This also means that those prairie otters sleeping soundly in the maintenance room have never been active in this third-level fortress.
So the question becomes, since they have no interest in this place, why do they still want to dig a passage leading here?
If it hadn't been for the discovery just now, Chen Ziyan wouldn't have thought about this kind of thing, but now he couldn't help but think about it.
Although this speculation is unbelievable, but combined with the gap in the door, it is probably the truth of the matter!
It is easy to see that the gap in the iron door behind you was torn open by some kind of creature, rather than caused by human tools.
If it weren't for the equipment blocking the iron door, they might have immediately thought that it was the prairie land otter.
"This..." Hu Bayi looked at the gap in the door and couldn't help but ponder.
Although there were still many things that didn't add up, he had to admit that Chen Ziyan's guess was very consistent with the current situation.
If you put it this way, everything can be connected together.
There was one or a group of people who had been here before, and they knew the situation here very well, so they used some method unknown to them to drive the prairie otters to dig a passage directly from the ground to here.<
/p>
This can also explain why they did not find traces of other people coming in and out of the secret fortress, because that group of people never entered the fortress at all.
It is even very possible that they did not know that there was a fortress before entering here.
Wang Kaixuan also thought about it, but after a while he felt his head hurt and said, "Let's go down and have a look. What's the use of thinking here?"
Chen Ziyan nodded: "The fat man is right. If you want to figure out what's going on here, you still have to go down and look for other clues."
The words are rough but the reasoning is not rough.
Wang Kaixuan is right. The situation here is clear at a glance, and there will be no gains if you continue to stay.
If you don’t have enough time to think about it, you might as well go to the lower level to find it.
If, as he suspected, some people had visited this place before, they would probably have left traces on the next floor.
Although there is no evidence yet, based on the clues he knows so far, combined with some of his guesses, Chen Ziyan feels that those people should have come with a certain purpose, and it is not a pure adventure like them.
Wang Kaixuan had already been a little impatient. When he heard Chen Ziyan's words, his fat body immediately moved past him and Hu Bayi and walked excitedly down the stairs.
Fortunately, there is a small platform here, otherwise the fat man would not have even thought about completing this operation.
Seeing Wang Kaixuan walking down the stairs, Chen Ziyan and Hu Bayi also followed.
The staircase was not very long, and it reached the bottom in just three or two steps. After rounding the corner at the bottom, a room exactly like the one upstairs appeared in front of them.
In the center of the room is an experimental bench, and on the walls around the room are transparent glass jars of different sizes.
These glass jars are filled with unknown brown liquid, and the liquid is soaked with creatures that are familiar or unfamiliar to them, including pig-faced bats, prairie ground otters, and the weird weasel that Wang Kaixuan is carrying.<
/p>
"This seems to be the main body of the laboratory." Hu Bayi glanced across the room and said.
Although he didn't understand experiments, he could guess the purpose of this room based on what he saw.
Chen Ziyan did not say a word, but carefully observed the laboratory in front of him. At this time, he had a bold guess in his heart.
Maybe...the creatures in these containers are still alive now.
As for the reason, naturally he saw a damaged jar next to the container that also contained the weird weasel. It was also the only damaged container here.
