So far, the missing Kong Anping and Instructor Li are still nowhere to be found, and I don't know where they are now or whether they are still alive.

The ship was a mystery inside and out, and from the moment I saw it, I felt as if I was in a thick fog. Strange things happened one after another, but I didn't understand any of them, and the so-called clues were all speculation and conjecture.

This situation is very abnormal, and I think that everything should have a reason for it to happen or exist, even if it is accidental, there should be a prerequisite for it to happen.

This mysterious spaceship is a real existence, but we have walked around it, but we have never been able to figure out the reason for its existence, and this is what makes me most uneasy.

I thought about it as I hurried, and before I knew it, I had reached the end of this passage.

In front of our eyes was a heavy lifting iron door, which was very black and huge. I walked over and knocked on it, and found that the voice was muffled, and it seemed that the door was thicker than I had imagined.

In my impression, I am afraid that only the underground fortifications that prevent nuclear weapons will build the doors so strong that they cannot be blown open even by artillery bombardment.

Looking at the iron gate, I couldn't help but wonder secretly, with such a door, what is this to defend? Is it to block the contents of the door?

I took a few steps back and looked around, and there was nothing but the iron gate, which was a bare wall. I couldn't help but wonder even more, why didn't I see the switch?

This kind of huge lifting iron door is generally opened by hydraulic pressure with a powerful engine, so it is necessary to have a start switch inside and outside the door. But there is only one door here, how can this be opened?

Others also discovered the problem and scattered around to search the area. They thought that the mechanism that opened the door might be hidden in the dark. As a result, after looking for a long time, I found that the wall and the ground are solid, and they are very flat, not to mention that there is no secret door, there is not even a gap, and the so-called hidden switch cannot exist at all.

Everyone was puzzled, and they discussed and guessed for a long time, but they had no clue.

Shen Hao was whimsical, he actually thought that we were thinking complicated, and this door could actually be opened by someone carrying it. As a result, under the speechless gaze of everyone, he spent a lot of effort, and he didn't shake the iron door at all.

An Beimo came over and told me that if the corpses in the passage were here to deliver goods, and there were empty boxes outside, it meant that the contents of the boxes were taken out by them and sent into the iron gate. Because there is no other way here, the only way to enter this passage is to go here.

And when they were attacked, they should have been intercepted and killed on the way back after completing the mission.

We searched the bodies and they didn't have anything on them. Since there is no device to open the door, it is very unlikely that they have the "key" to open the door.

Or maybe the "key" is on someone else, and that person has fled in the space shuttle. However, this is not very likely, if there is a "key", then there should be a "keyhole" here.

Personally, I think there should be other ways to open this door, but we didn't find it. The secrecy work is done to the extreme, no matter what form the "key" is, there is a hidden danger of leaking secrets, and I prefer that this door has no "key" at all.

As the minutes ticked by, we studied for half an hour but still couldn't guess the mystery. Everyone started to get a little irritable, and their ideas gradually became wild, and Instructor Zhao even came up with the strange idea of a blood sacrifice.

Feng Jiutian stared at the iron gate for a long time, and suddenly said that the mechanism that was opened would not be on the iron gate. So she went to the iron gate and groped around it.

Just when we all thought that this was unlikely, and we didn't know where Feng Jiutian had touched it, the iron gate, which had been silent, suddenly heard a dull sound, and it was slowly rising upward.

All of us were taken aback, especially Feng Jiutian, who was closest to the Iron Gate, and the behemoth in front of her suddenly moved, and she was suddenly startled and retreated back to us.

Who knew that as soon as Feng Jiutian left the iron gate, the iron gate that was originally rising and opening actually slowly fell again, and closed with a "bang".

Everyone looked at each other, and Shen Hao hurriedly asked Feng Jiutian what he had touched just now, whether he had found the mechanism to open the door.

Feng Jiutian looked dazed, shook her head and said that she hadn't found anything, and there was no mechanism on the iron door. She didn't know what was going on, and the door suddenly opened.

Shen Hao didn't believe it, and ran to the iron gate to find it in person. I was afraid of danger behind the door, so I took a gun to the side to take cover.

But Shen Hao almost touched the iron door, and the iron door didn't move at all, and finally Shen Hao said to me with a puzzled face, there was indeed nothing on the door.

Instructor Zhao thought that Shen Hao's inspection was not meticulous, so he went over to help grope for the door, and after a while, Gu Nan also went over to help.

The strange thing is that these three people searched almost every inch of the iron gate, and they didn't find anything, and there was no movement in the iron gate.

I suddenly realized something, and turned my head to look at Feng Jiutian. At the same time, An Beimo said lightly: "It seems that only a doctor can open this door!" ”

Everyone immediately focused their eyes on Feng Jiutian, Feng Jiutian looked innocent, and explained: "Don't all look at me like this, I didn't do anything just now, I didn't find the mechanism, what I said is true!" ”

I said, "Maybe there's no mechanism on the door, but this door only recognizes you!" ”

Feng Jiutian was stunned for a moment, and asked me puzzledly: "What do you mean by this?" ”

I said, "Don't be nervous, we'll try again." Saying that, I beckoned the three people in front of the door to come back, and then said to Feng Jiutian: "Now you go over and try again, and repeat all the actions you did just now." ”

Feng Jiutian's expression was very complicated at this time, and she didn't think that the iron door was opened just now and had something to do with her. Hearing that I asked her to try again, she did as I said, and slowly walked towards the iron gate. I let the others disperse to the sides to cover, in case the door is really opened, it will definitely protect Feng Jiutian's safety.

Seeing that we were on full alert, Feng Jiutian was a little nervous, and I comforted her and said, "Don't worry, we will do our best to protect you and won't let you be in danger." ”

Feng Jiutian nodded and slowly walked to the iron gate.

It's strange to say, as soon as Feng Jiutian approached this time, before he made any movements, the iron door actually made a heavy sound again, and it really slowly opened again.

At this time, Feng Jiutian himself was also stunned, and he couldn't imagine that the key that could open this door would actually be himself.

The iron door did not rise quickly, and I immediately lay on the ground and shone the spotlight under the muzzle of the gun into the crack under the door. The others followed my example and fell to the ground, their guns pointed at the space behind the door.

Feng Jiutian saw that we had a serious expression, thinking that there was something dangerous behind the door, so he couldn't help but take a few steps back and stay away from the door. When she was four or five meters away from the iron gate, I saw the rising iron gate suddenly stop and fall.

"Don't leave the iron gate, stand in front of it!" I shouted to Feng Jiutian, "You still don't understand? As soon as you get close, it reacts! And if you are beyond a certain distance from it, it will turn off. You don't have to worry about being behind the door, I promise you'll be fine. ”

Hearing my words, Feng Jiutian, who was a little nervous, walked back. Sure enough, as soon as she got closer, the iron door continued to open again.

It was dark behind the door, and our lights were all submerged in the darkness when we got in, and although I couldn't see clearly, I could feel that the space inside was huge.

At this time, the iron door was already half opened, and as soon as I waved, Shen Hao and I grabbed it at the same time, raising their guns and guarding both sides of Feng Jiutian. Seeing that Feng Jiutian was still in place, I pulled her and let her lie on the ground.

However, it was unusually quiet behind the door, and no moving objects were seen.

After a few minutes, the iron door opened completely, and the heavy grinding sound disappeared. I didn't dare to let my guard down, and waited a few more minutes to make sure that there was no danger for the time being, and then I stood up.

Seeing that I was standing still, Shen Hao asked me, "What are you waiting for?" Let's go inside. ”

I said, "Don't worry, I need to figure out something before I go in." After speaking, I looked at Feng Jiutian who was slowly standing up next to me, and couldn't help but say, "Why are you the only one who can open the door?" I just don't understand. ”

When Feng Jiutian heard my words, he immediately said to me, "I said, I don't know!" You don't suspect that this door is related to me, do you? ”

Of course I don't doubt her, I seem to be asking her this question, but I'm actually asking myself. Don't say I won't doubt it, and I guess the rest of the D.R.T. won't doubt Feng Jiutian either.

But Instructor Zhao and Gu Nan didn't think so, they surrounded Feng Jiutian in the middle, one left and one right, and Instructor Zhao was the first to ask: "Doctor, why can't all of us, only the door will open when you approach?" Who the hell are you? ”

Gu Nan also said: "Doctor, it's not that we embarrass you, but this matter is really strange, it's better for you to explain it to us." ”

Being asked like this, Feng Jiutian was obviously uncomfortable, her face changed, her eyebrows were slightly raised, and she suddenly showed a proud look, and said, "I already said I don't know." How? You don't believe me? ”

Instructor Zhao said: "I don't know you well, I haven't dealt with you before, and I know almost nothing about your identity, how can I trust you?" With the facts in front of us, I guess everyone should ask why, right? ”

Hearing these words, Feng Jiutian was even more unhappy, perhaps because of some mood fluctuations, she held the gun hand and moved, holding the gun tighter.

Instructor Zhao was standing opposite Feng Jiutian, but he didn't expect such a small action to cause him to misunderstand, he suddenly raised his gun and pointed it at Feng Jiutian, and shouted: "Don't move!" If you dare to mess around, don't blame me for being rude to you! ”

The sudden change stunned everyone, Gu Nan felt that Instructor Zhao had done a little too much, and hurriedly said to him: "Hey! What are you doing? If you have something to say, put the gun down! ”
