This gate is not actually the main gate of the base built by the Doug family on Mars, but a small door that is not usually used. The gate that Eric took Tang Feng into the base that day, that is, the door on the cliff of Mariner's Grand Canyon that could enter and exit the aircraft, was the main gate of this base.

But even so, the small door was big enough. When they walked up to Tang Feng, they found that this gate was more than ten meters high and more than twenty meters wide, and it might be a little difficult to get in and out of the aircraft, but there was absolutely no problem for ordinary large-scale engineering equipment on the earth to enter and exit.

This also shows the advantage of the Doug family's tall stature, and the buildings everywhere are generous

As soon as I walked through the door, my vision darkened. Tang Feng and the three of them unscrewed the spotlight on the helmet above their heads, only to find that there was a closed door not far in front. Between these two gates, there is a space of about 30 meters in length and width. The entire space is wrapped in an unknown metal, which is extremely smooth.

"This should be a storage zài similar to an airtight cabin." Han. After observing for a while, he said with great certainty, "It seems that the living habits of these aliens are similar to those of us earthlings, and the atmospheric conditions of Mars are not suitable for these aliens." ”

Not to mention, Han. Zheng's guess is really accurate. The Doug family and the earthlings are actually a kind of human being, and they are both very similar in terms of genes.

Tang Feng said: "Let's look for it first, and see if we can find the switch that controls it." Even if this is an airtight cabin, then we have to let the air pressure in it recover before we can move on. ”

Alexander was a man of action, and when he heard this, he immediately walked towards the open door, and soon the guy found several buttons that resembled switches next to the door.

Alexander glanced at Tang Feng, Tang Feng nodded, so the guy pressed those buttons without hesitation. I don't know if it was the button that worked, or if all the buttons worked, but the open door closed completely in a matter of seconds, and at the same time, the airtight cabin was also brightly lit, and rows of light sources of unknown shape suddenly illuminated the entire room.

The next moment, with a "hissing" audible sound, all three of them could see through the multifunctional microcomputer on Guò's left wrist that the air pressure in this space had recovered to one atmosphere of pressure almost in a matter of seconds. And through the detection of the guò microcomputer, the air here is almost the same as the earth, and even if there is a difference, it is that the oxygen content is slightly higher

Alexander was stunned: "It is worthy of alien technology, the technology used in a small airtight cabin is something that the earth has not been able to overcome for decades, I really look forward to what surprises are waiting for us in the base!" ”

Alexander is indeed right, not to mention such a large "air-locker", even the air-lock on the "Prince Barnett", which is currently the most advanced in the world, does not even have one percent of this space, but if the astronauts want to enter and exit the air-locker, it will take at least more than ten minutes.

Where is it like here, the door closes and the air pressure recovers, and it only adds up to less than ten seconds!

Tang Feng said with a smile: "When I have a chance for you to study the equipment here, maybe you can apply it to the spacecraft where it is after you crack it." When the time comes, I'll find someone to apply for a patent for you."

Alexander smiled and said, "Tyrant, I remember what you said, if you don't handle this when you return to Earth, I will go to your house to eat." ”

As he spoke, the closed door in front of him quietly opened, revealing the situation inside.

Tang Feng motioned to Han. Just as the two of them didn't move for a while, they raised their hands again and looked at their left wrists, and then reached out and took off the helmet of the spacesuit. He exclaimed with Alexander.

"It's okay, you two can take it off too, the air and air pressure here are like we are in a big forest on the earth, yes, very good, much more comfortable than holding a spacesuit."

Han. The two of them didn't know the situation, but Tang Feng couldn't be clearer. Just before Eric left, Tang Feng had completely taken over the main control computer here, that is to say, from now on, Tang Feng was actually the new owner of this base.

The main control computer of the base, as well as the core energy source, were sealed underground by Eric at a depth of several kilometers. The two of them were in a hurry, and there wasn't enough time left for Eric, otherwise Eric could use their technology to create a master computer similar to a supercomputer on Earth to monitor the entire base. Now this main control computer is still a computer made using the technology of the Doug family, and its function is many times more powerful than the so-called supercomputers on the earth.

But stay and stay. This main control computer and the small size, but the powerful mess of the nuclear fusion reactor were enclosed by Eric in the lowest secret room, if Tang Feng, the new owner, did not agree to open it, with the earth's scientific and technological civilization, even if it was blown up with a hydrogen bomb, it would not be able to blow up the secret room, but there was no need to worry about what damage would be caused to the equipment on the side after the earthlings immigrated to this base in the future.

Now Tang Feng knows the entire base well, and naturally knows that the air in it does not cause any harm to humans at all. So Tang Feng took the lead in taking off his helmet and began to take off the heavy spacesuit again.

With Tang Feng as an example, after a while, Han. Zheng and Alexander also took off all the spacesuits on their bodies, but took off the instant cameras on the spacesuits and fixed them on their respective shoulders. Every qiē here needs to be recorded, and if possible, it needs to be teleported to the forward base and the earth

Alexander jumped with a smile, let out a strange cry from his mouth, and said, "Tyrant, Han, you said that if we hold a sports meeting here in the future, will I win the high jump championship?" ”

The gravity of Mars is much smaller than that of Earth, and although it is not as high and farther as jumping on the moon here, even if it is an ordinary person's high jump score, I am afraid that it can break the high jump world record on Earth.

Tang Feng smiled and nodded, then didn't bother with the goods, and led the way behind the gate.

Behind this gate is a roadway that leads diagonally downward, boxy, I don't know how deep, even if there is a light source, but there is no end in sight.

At the top of the alleyway is a bottomless stairwell. Not to mention, the staircase is still usable even in a highly developed civilization like the Doug family. It's just that this stairwell doesn't know how deep it is, anyway, you can't see the bottom at all when you look at it.

Han. Zheng also said with a bitter face: "Boss, we won't just go on like this, right?" What time will it take! ”

Tang Feng shook his head and pointed to the stairwell and said, "This alley should be the passage for the alien spaceship when it flies out of the underground base, and as for this stairwell, it should be the passage used by the aliens to walk or overhaul." Of course, do you see the door next to the stairwell? If my estimate is correct, it should be an elevator similar to an elevator. Let's go over and have a look. (To be continued.) )
