If it weren't for this discovery, Lin Bin wouldn't have known that this underground ruin was still alive. He was also secretly glad that he had been tinkering with the space boxes he had collected, and that he hadn't immediately looked for some door to try to open. And one thing is certain, the "demon" must have discovered his existence, anyway, no matter what method is used, the "demon" just discovered his existence, and he will attack when he is impatient.

"Stay, or go?"

"Do you want to try to open a door, or stay in the plaza and continue exploring?"

Wandering left and right in his mind, Lin Bin had more thoughts of leaving than staying, because he didn't know what would be behind which door.

"Let's go!"

Since he had an idea, Lin Bin did not hesitate, his range of activities for more than a month was also a range of four or five miles, and he was originally exploring ways to go back, and the idea of taking risks was only incidental.

All the way back, it took Lin Bin more than four hours to return to the exit, which took about twice as long as when he came in.

Of course, there is a reason why it will be slower, and that is because he unraveled the "shell" of all the undamaged corpses, and also collected more space boxes along the way, and by the way, he also collected a few crystallized corpses left by the demons.

When I came out, it was relatively calm outside.

On the other hand, it is because with the naked eye you can see that there are towering tornadoes in the distance, and some areas are covered with lightning and thunder, and this side is just a wild dance of wind and sand, but it is not enough to blow people off the ground.

Because it was not too far from the previous basement, Lin Bin chose to go back to the basement first, and when he entered the basement, he immediately took out a "fluorescent liquid" and sucked it clean at one time, shouting "Cool!" Sitting cross-legged on the ground, he concentrated on "digesting" the excess nutrients that were like a "fluorescent" liquid, and then opened his eyes.

"I don't know what kind of liquid is refined, but the effect is so strong!"

Lin Bin didn't know what the "fluorescent liquid" was in this foreign civilization, maybe it was also an auxiliary item for cultivation, or it was really a food, but he was very satisfied that he could find something to eat.

Sitting on the ground for a while, Lin Bin took out some things that had been studied or not studied.

"How do I charge these things?"

It can only be said that it is at a loss, as if the ancient people suddenly went to modern times and did not understand what the socket is. Since you don't understand it, you won't use it, and the reason is as simple as that.

"Grandma is a bear, I'm not much better than a primitive now!"

The discovery that there are still "living" creatures on this planet made Lin Bin's heart a little hairy.

I used to think that everything in this place was full of death, anyway, I didn't see anything alive, not even a living grass, thinking that it was like that, although Lin Bin would be nervous and lonely, but at least he had some spectrum in his heart.

Now, Lin Bin has discovered the first living creature, and guesses that it is a monster or humanoid creature that has invaded this different civilization, of course there will be two, or even more, and it must be false to say in his heart that he does not feel fear. He was in dire need of something to protect himself right now.

"Charger, charger! This thing is clearly a weapon, but it has no energy! This damn alien civilization is an epoch-making product, can't it make some knives and swords...... Can you cut people with weapons like that!? ”

Lin Bin was very, very depressed, sulked for a moment, and looked up at the light source floating in the air in a daze.

"If there are invaders still alive, does that mean that there will be survivors in other civilizations? If there are survivors in another civilization, where should they be? ”

In the final analysis, Lin Bin's range of activities is only four or five kilometers, and he has not been to too many places, so what he can find is very limited.

"This special dress comes with temperature regulation, it's really a bunch of aliens who know how to enjoy it. I can't find anything like wires, I'm almost at the ninth level of basic martial arts, and I can't even tear up such a piece of clothing! ”

Lin Bin was very firm, the technology of the alien civilization must be higher than that of the earth, and it is impossible to determine how high it is, anyway, if he wants to vent his fear, he can't tear his clothes.

"I'm xx your oo's ab!"

Lin Bin, who was very irritable, directly threw the clothes in his hand and threw them into the air, and then a magical thing happened!

"Huh? Why is it dark again!! ”

Crazy, depressed, irritable, almost all emotions that can be related to fear appeared on Lin Bin this time.

"Fortunately, it's daytime, not a special night season, otherwise Lao Tzu would have stayed in the dark for more than ten days!"

With some of the light shining in from the entrance of the basement, Lin Bin naturally continued to slap the hemisphere in the past, and the sound of "ping pong" was accompanied by the shouting of "Hey, hey, Hai!" He was so shocked by a shock that he flew out and fell to the ground.

It seemed that after venting his brain and calming down, Lin Bin suddenly remembered such a thing.

"No, I've tried touching the light source body, and I haven't gone out when I touched it more than once, this time ......"

After another burst of operation, the basement was back bright, Lin Bin immediately took the dress just now to observe, this look noticed a detail, it seems to be a "charging" thing that appeared, a green light groove appeared on the left chest of the clothes, showing that it was almost full.

"Huh! Don't......? ”

Without saying a word, Lin Bin took out another piece of clothing from the space box and threw it towards the floating light source body, this time the light source body disappeared again without accident.

"Got it, got it! This alien way of charging is not a wire socket! The floating light source body has a charging effect! ”

This discovery made Lin Bin extremely excited, he excitedly went over to slap and "hey, hey" at the hemisphere again, waiting to be shocked out again, this time he didn't take his clothes, but put a thing that looked like a weapon towards the light source body, and then ......

"It didn't work? How could it not be effective! ”

Yes, there is no effect, even if Lin Bin stabs a part of what looks like a weapon into the small light source body, the light source body is still glowing, and it is not like the clothes that come into contact and then be "absorbed".

"What is the reason? That's right...... The weapon must have something like a safety device, and the energy device should also be wrapped in the body. So where is the energy storage device for this thing, or how do you get it out and charge it? ”

The next thing is to tinker with the things that look like weapons, Lin Bin is about to touch every detail of the things in his hand, and finally figure out some ideas.

"Only the base has obvious gaps, and the rest of the thing is in a state where there are no gaps. Then this must be the card slot for the energy device, just get it out......"

Touching, touching, relying on the touch of his eyes and hands, Lin Bin didn't let go of the slightest bump, tossed for about half an hour, and with a "click", guessed that the part of the energy card slot was finally loosened, and then he took it off!

"It's not easy, it's really not easy, it's finally out!"

In an instant, Lin Bin immediately jumped up directly from the posture of sitting cross-legged on the ground, and couldn't wait to put the card slot he got out towards the light source body, but the collapse happened, the light source body was still "glowing", and there was no sign of being "absorbed" at all.

"Bought a watch last year! Definitely bought a watch last year! ”

originally thought that there was a new discovery, but the result was very frustrating, and almost an hour of tossing was equivalent to working in vain, so that Lin Bin regained his sluggish expression.

"That's right! It's kind of like it can be plugged in that place! ”

Lin Bin's face returned to an excited expression, if he remembered correctly, it seemed that he had found something in some war equipment in the square.

"Go back, go back to the underground ruins!"

Just do it, Lin Bin didn't clean up the things he had just messed up, he ran out of the basement with his legs, and then ran towards the entrance that led to the underground ruins before.

"O dark clouds, dark clouds that cover the sky. The wind is getting stronger and stronger, depending on the direction of the wind, the dark clouds will be blown this way, but don't be covered by lightning again, otherwise it will ......"

Two months of experience have given Lin Bin a little understanding of the weather on this alien planet, he has seen a scene covered by lightning, which is like being in a world of thunder and lightning, and there are "electric snakes" running around everywhere. What's worse is that once the lightning covers come, the world's energy system seems to have problems, and everything that can be related to energy will fail.

"That's not right! When lightning is covered, will the energy system of the underground ruins also be disturbed? ”

Lin Bin, who had already run into the corridor passage, was suddenly a little stunned when he went deep for about 1,500 meters, but he didn't forget that at least one "demon" was blocked by the light film of the door on the other side of the square, if the energy system of the underground ruins also failed when the lightning was covered, and the "demon" was released, then something would happen.

"The underground ruins are at least 500 meters deep underground, and the passage to the square is more than 5,000 meters long. In addition, since there is no 'demon' in the square, does it also mean that the barrier system of the door has been working for a long time? ”

Lin Bin still decided not to take any luck, turned around and immediately ran back and forth, he didn't want to hand over his safety to any unreliable fate.

The result......

"What! The light film at the entrance has been restored!? ”

Yes, the light film at the entrance recovered, as if something had happened, and then the barrier system recovered on its own under some kind of action.

Lin Bin didn't want to stay in this ghost place that looked like a war relic, but he tried several times, but he didn't know if it was incorrect or for what reason, every time he operated, there would be some "words" of operation sounds, but the light film just couldn't be opened!

"The language is not comprehensible, the language is not comprehensible!"

Lin Bin didn't understand what those "words" were, but listening to the solemn voice, he could probably guess what big problems would be caused by the opening of the light film, so he just couldn't open it!

In the end, Lin Bin still couldn't get out, so he could only turn around again and walk in the direction of the square.

It took about forty minutes for Lin Bin's figure to reappear in the square, he first carefully observed the door with the "demon", and then ran towards the war equipment in his impression.

"Found it! This is it, there's a pedestal for card slots! ”

Some of the noises are obviously the friction sound of an object being put into place.

"That's right, that's it, that's it! Ha ha! Finally let me try it out! ”

In fact, this war equipment is already in a semi-destroyed state, fortunately there is still energy, and in front of Lin Bin are rows of concave slots. When you put the card slot you took out of the weapon and put it in, a row of bright color signs appeared in that position, and it looked like it was charging!

"Huh? So fast! ”

It's very fast! That is, about ten seconds, the marked row of energy charging shows that the whole bar is green, no matter how you look at it, it looks like a full energy grid.

"One, two, three...... as many as you want, anyway, one only takes ten seconds!"

After tossing for a long time, Lin Bin estimated that he had filled more than 300 card slots, and then he took out the weapon he had tested before, and aimed the charged card slot into the position.

"It's on, it's on!"

There was an electronic sound that sounded like a prompt sound, and something that looked like a built-in light appeared on the long weapon, and what was even more amazing was that a projection-like sight also appeared at the quasi-signal position, and a light screen appeared at the rear seat aiming position, but Lin Bin couldn't read the text displayed on the light screen.

"It should be that some kind of operation is needed to unlock the weapon's safety device. Green usually represents safety, red represents danger, that is, press the red position to unlock? ”

It turned out that Lin Bin's conjecture was right, he touched the red position on the light screen, and then the guy in his hand was prompted by an electronic sound, and the trigger device that he hadn't seen before also appeared.

The square in the basement suddenly emitted a "boom" sound, because it was the environment of the secret room, no matter how big the secret room was, the small sound would be increased.

"Is it a Gaussian-like weapon?"

Yes, yes, Lin Bin had already pulled the trigger once, and the location was the wall of the war equipment, and a small crater appeared in the place where it was hit, but it was obvious that it did not penetrate.

"The material science of this alien civilization is very powerful, and this thing is another weapon of war, and a single weapon cannot penetrate it, which does not mean that the weapon is not very powerful!"

Lin Bin wanted to take out other guys who looked like weapons to test them one by one, but a "bang" appeared again, and he walked out of the war machine and looked at the source of the sound, it was definitely not the door where there was a "demon" before, it was another one.

What happened next once again confirmed that Lin Bin's memory was very good, because the door with the "demon" before was also being attacked, and then the scenes that continued to happen made him breathe rapidly, because more and more doors were being attacked!

"Seventeen, there are seventeen doors with 'demons' behind them!"
