Alien Relic Hunter.

Chapter 99 The Airtight Door

This airtight door is very large. Ke Lan visually measured it to be nearly five meters high and more than two meters wide. The entire door panel is made of a dark green alloy. An octagonal valve with a diameter of more than half a meter is installed. In the middle of the door panel, the metal handle is covered with rust.

Valves with purely mechanical structures are not common in the remains of the Alvin civilization. Most of their devices are driven by energy crystals, even the doors are no exception, and the airtight door in front of Ke Lan appears. , on the contrary, it is closer to the design style on the side of human civilization.

"Isn't this place transformed by humans?" An idea came to Ke Lan's mind, but he quickly rejected it by himself—let's not say whether anyone has ever entered this place, just look at this place. The degree of rust on the airtight door, it is estimated that this thing has been installed here for at least hundreds of years... and humans have only come to Alpha Planet for only 50 years.

"Well... Hundreds of years are still too conservative, I'm afraid it will be tens of thousands of years..." Ke Lan poked the door panel with his finger, but found that his finger was instantly sunk in half - this dark green thing is not at all. The original material of the door panel, but the alloy was oxidized to form a flocculent substance similar to rust. As for why it appeared this color, it must be that the formula of this alloy contains a lot of copper elements.

"But it's not right... The metal plates and metal frames used to reinforce the passage in other places are not so corroded... Logically speaking, the material used for this door should be better or worse than those places. Why does this door rust so badly?"

Ke Lan pondered for a few seconds, and then said in a somewhat uncertain tone: "Could it have something to do with what's behind the door?"

He glanced at the large characters engraved next to the airtight door - "First Level". Semantically speaking, these alpha characters should not have too much deviation in interpretation, but because of this, these characters have different meanings. The information that can be provided is also extremely limited.

Do you want to open this door?
Ke Lan's heart suddenly hesitated: the stalagmite on the corpse was pulled out before, awakening the erosive seed that had been in a state of suspended animation for decades; later, the ore on the stone pillar was pried off, causing the seawater to pour into the cave, almost Drowning in a hole... This time, if you open the door rashly, something terrible will happen again, right?
To be honest, Ke Lan is really a little cowardly...

As a relic hunter, being cowardly is not necessarily a bad thing. As the old dog said, those who are daring will die long ago, and those who are cowardly can live until now.

After thinking about it for a long time, Ke Lan finally decided to give up - his luck seems to be not quite right today, who knows what ghosts and snakes will be waiting for him behind this door. By then, even if he regrets it, it will be too late.

Ke Lan took out a circle of tape, tore off a few pieces, and pasted them on the crack of the airtight door and the shaft at the other end, and then continued to walk forward.

The sound of the water flowing overhead disappeared. It seems that the seawater from the outside world is no longer pouring into it. After all the seawater enters the reservoir, the cave above will be able to pass.

However, Ke Lan did not plan to go back to the top. After knowing that the drainage system of the Alpha people has the ability to deform at will, the original "underground labyrinth" was directly upgraded to a more difficult "moving labyrinth". With the design drawings for the construction of the drainage system, he may not be able to get out of it - after all, no one can predict when the water flow channel will change, and he does not know the incentive and purpose of the change. .

In contrast, this cave, which may be the "maintenance channel", is much more stable.

……

After walking another four pieces of chalk, Ke Lan was forced to stop.

It was another landslide, but this one did not even leave a gap. A large amount of gravel blocked the passage so tightly that even the snake-shaped robot designed to explore small pipes could not get through. .

The only useful tool in Ke Lan's hands was a folding pickaxe found in the 776 squad's camp. Based on his physical strength, if he wanted to clear up the one-meter-deep gravel, he would have to Spend the whole day.

The previous section of the collapsed passage was seven or eight meters long. If this section were that long, Ke Lan would have to dig for a full week.

Moreover, the further you go, the worse the situation in the tunnel, and it is estimated that such landslides will only increase.

"Alas." Ke Lan sighed helplessly, "It seems that we still have to go through that door."

A mark was left on the landslide, and Ke Lan could only turn around again.

Following the chalk line on the wall, he returned to the huge airtight door.

The tape on the door that was used as a seal was intact, which made him relieved-according to the common scenes in horror movies, the tape above should have been torn at this time, and then add something to hide Figures in the dark and the like...

However, this kind of plot, in the remains of the Alpha civilization, is not surprising... Ke Lan has read many tomb robbing novels from the old era. Compared with the high-tech traps of the Alpha civilization, the organs of those ancient tombs are only It can be regarded as a pediatrician, and things like zongzi ghosts are even more insignificant in front of the erosive seeds.

"...This valve...is really high..."

Ke Lan stood on tiptoe and stretched his arms up as much as possible, but he could only grasp the lower edge of the valve and couldn't turn it at all.

"It seems that the data published in the official documents is quite accurate..." For the Alpha people who are about [-] to [-] meters tall, the size of this airtight door is not exaggerated, and the height of the valve is just right. But for humans, that's a bit of a hassle.

There was no other way, Ke Lan could only hook the valve with a pick and turn it little by little by constantly pulling it down.

There was a sour friction sound between the metal and the metal, and large pieces of dark green oxide fell off... Fortunately, the mechanical structure inside the valve was still intact. When pulling the valve, Ke Lan even I can still clearly feel the force of the gears meshing between the gears - if these gears are as rusted as this door panel, then it is estimated that only one valve is idling bare there, even if Ke Lan turns a few hundred circle, and may also open this door.

"Crack."

A crisp sound came from the inside of the airtight door, followed by a continuous metal collision. Ke Lan waited for [-] seconds before the crack of the airtight door "popped" and opened. A tiny gap.

The door opened.
