If it weren't for this discovery, Lin Bin wouldn't have known that there were still some living underground ruins. He was also secretly glad that he had been fiddling with the space boxes he had collected just now, and he was not looking for a door to try to open it. One thing was certain that the "demon" must have discovered his existence. No matter what method was used, the "demon" discovered his existence and only attacked him when he was impatient.

"Stay, or leave?"

"Stay open a door, or stay in the square to continue exploring?"

He was wandering around in his mind, and Lin Bin had more thoughts about leaving than staying because he had no idea what would be behind which door would be.

"Walk!"

Since he had an idea, Lin Bin did not hesitate. His range of activities for more than a month was only four or five miles. He was originally exploring the way to go back, and his adventure was just a side effect.

It took about four hours to return all the way back, Lin Bin returned to the exit, which took about twice as much time than when he came in.

Of course there is a reason why it will be slower, because he untied all the undamaged corpses, collected more space boxes along the way, and also collected several crystallized corpses left by the demons.

When I came out, it was relatively calm outside.

To put it in contrast, it is because you can see towering tornadoes in the distant places with your naked eyes, and some areas are covered with lightning and thunder. Here, there is nothing but wind and sand dancing, but it will not blow people away from the ground.

Because it was not too far from the previous basement, Lin Bin chose to go back to the basement first. When he entered the basement, he immediately took out a "fluorescent liquid" and sucked it clean at once, shouting "Function!", sat cross-legged on the ground, gathering his heart to "digest" the excess nutrients brought by the liquid like "fluorescent liquid", and then opened his eyes.

"I don't know what kind of refining this liquid is, it's so effective!"

Lin Bin didn't know what "fluorescent liquid" was in this alien civilization. It might be an auxiliary item for cultivation or really a food, but he was very satisfied to find something to eat.

Sitting on the ground and being stunned, Lin Bin took out some things that he had studied or had not studied.

“How to charge these things?”

I can only say that I am confused, just like ancient people suddenly went to modern times and could not understand what the socket is. Since I don’t understand, I will not be able to use it. The reason is that simple.

"Grandma, I'm not much better than the Primitive Man now!"

The discovery of "living" creatures on this planet made Lin Bin feel more or less furious.

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. I thought it was just like that. Although Lin Bin would be nervous and lonely, at least he felt a little confused.

Now, Lin Bin has discovered the first living creature, and he guessed that it was a monster or humanoid creature that invaded this alien civilization. Of course, there would be two, or even more. It would be fake to say that he didn't think he was afraid. He urgently needed some things that could protect himself.

"Charger, charger! This thing is clearly a weapon, but it just doesn't have energy! This damn alien civilization is a landmark product. Can't we make some weapons that can cut people with swords, swords, etc.?"

Lin Bin was very depressed, and after a suffocation, he looked up at the light source floating in the air and stared blankly.

"With invaders still alive, does that mean that there are survivors in different civilizations? If there are survivors in different civilizations, where should they be?"

After all, Lin Bin's range of activities is only four or five kilometers, and he has not been to many places, so the things he can find are very limited.

"This fucking clothes come with temperature adjustment. They are really a group of aliens who know how to enjoy them. They can't find things like wires. I'm almost at the ninth level of basic martial arts, but I can't even tear such a piece of clothing!"

Lin Bin was very firm. The technology of a different civilization must be higher than that of the earth. As for how high it is, he cannot determine it. Anyway, if he wants to vent his fear and pull his clothes, he can't pull them.

"I xx your oooo ab!"

The very annoyed Lin Bin shook the clothes in his hand and flew into the air, and then something magical happened!

"Ah? Why is it getting dark again!!!"

Crazy, depressed, irritable, and almost all emotions that can be linked to fear appear on Lin Bin this time.

"Fortunately it's daytime, not a bad nighttime, otherwise I'll be so stupid that I'll stay for more than ten days!"

With some light coming from the basement entrance, Lin Bin naturally went over and continued to slap the hemisphere. A slap of "ping-pong" sound was combined with the shouting "Hehe Hay!", and he was shocked by a shock force and flew backwards and fell to the ground.

It seemed that after venting his mind, Lin Bin suddenly remembered something.

"No, I have tried touching the light source body, and it has not been extinguished after touching it more than once. This time..."

After another operation, the basement was bright again. Lin Bin immediately took the clothes just now and observed it. He noticed a detail, which seemed to be something that only appeared after "charging". A green light groove appeared on the left chest of the clothes, which showed that it was almost full.

"Huh! Could it be..."

Without saying a word, Lin Bin took out a piece of clothing from the space box and threw it towards the floating light source body. This time, the light source body underground disappeared without any surprise.

"I understand, I understand! The charging method of this alien civilization 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 and slapped the hemisphere and "Hehe Hayi" again, waiting to be shaken out again. This time he was not taking clothes, but turning a thing that looked like a weapon towards the light source body, and then...

"No effect? ​​Why is it uneffect!"

Yes, it has no effect. Even if Lin Bin stabbed part of the weapon into a small light source body, the light source body was still emitting light, and it was not touched and then "absorbed" like clothes.

"What's the reason? By the way... the weapon must have something like a safety device, and the energy device should be wrapped in the body. So where is the energy storage device for this thing, or how to get it out and charge it?"

Next, he made some trouble with the things that looked like weapons. Lin Bin was almost touching every detail of the things in his hand, and finally figured out some ideas.

"The whole thing only has obvious gaps on the base, and the rest of the things are in a state of no gaps. Then this is definitely a slot for the energy device, just make it out..."

Touch and touch. Relying on the touch of the eyes and hands, Lin Bin did not let go of any convexity. After about half an hour of tossing, he guessed that the part of the energy slot finally loosened, and then he took it off!

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

In an instant, Lin Bin immediately jumped up from the position of sitting cross-legged on the ground, and couldn't wait to put the slot out into the light source body. However, something collapsed happened. The light source body was still "luminous and hot", and there was no sign of being "absorbed".

"I bought a watch last year! I definitely bought a watch last year!"

I originally thought there was a new discovery, but the result was very frustrating. The effort of about an hour was equivalent to working hard in vain, so that Lin Bin returned to his dull expression again.

"By the way! This kind of installation device is a bit like it can be inserted in that place!"

Lin Bin's face regained an excited expression. If he remembered correctly, he seemed to have found something in some war equipment in the square.

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

He did it as soon as he said that, and Lin Bin did not pack up the things he had just messed up. He ran out of the basement and then ran towards the entrance leading to the underground ruins before.

"Dark clouds, dark clouds covering the sky and the sun. The wind is getting bigger and bigger. Judging from the direction of the wind, dark clouds will be blown toward this side. Don't cover them with lightning again, otherwise..."

The two-month experience has already given Lin Bin a little understanding of the weather on this alien planet. He has seen a scene covered by lightning. It seems that he is in a world of lightning, with "electric snakes" running around everywhere. What's more serious is that once lightning coverage comes, the energy system of this world seems to have problems, and everything that can be related to energy will fail.

"No! When lightning is covered, will the energy system of underground ruins be disturbed?"

Lin Bin, who had already run into the corridor, suddenly became stunned when he was about 1,500 meters deep. He did not 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 failed when it was covered by lightning and released, something would happen.

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

Lin Bin still decided not to be lucky, and turned around and ran back immediately. He didn't want to hand over his safety to any unreliable fate.

What's the result...

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

Yes, the light film at the entrance has been restored again, as if it had encountered something, and the barrier system recovers itself under some action.

Lin Bin didn't want to stay in this ghost place that seemed to be a ruin of war, but he tried several times, not sure if the operation was incorrect or for some reason. Every time he operated, some "words" of operation sounds appeared, but the light film could not be opened!

"I can't understand the language, I can't understand the language!"

Lin Bin couldn't understand what those "words" were, but listening to the solemn voice, he could probably guess what big problems would cause when the light film was opened, so he just couldn't open it!

In the end, Lin Bin still couldn't get out, so he had to turn around and walk towards the square again.

It took about forty minutes before Lin Bin's figure appeared in the square again. He first carefully observed the door with the "demon", and then went to the war equipment he had remembered.

"Finished! It's here, there is a base that can hold the slot!"

Some noises are obviously the friction sounds made by an object being placed in a suitable position.

"By the way, that's it, that's it! Haha! I finally tried it!"

In fact, this war equipment is already in a semi-destructive state. Fortunately, there is still energy. In front of Lin Bin are rows of concave slots. After putting them in from the slots taken out of the weapon, a row of brightly colored signs appeared at that location, which looks like charging!

"Huh? So fast!"

It's very fast! In about ten seconds, the energy charging row marked with a row of energy is green, and it looks like it's full of energy.

"One, two, three..., how many are counted, anyway, one only takes ten seconds!"

After struggling for a long time, Lin Bin probably had charged more than 300 card slots. Then he took out the weapon he had tested before and aimed the charged card slot at the position and inserted it.

"It's bright, it's bright!"

A burst of electronic sounds that sounded like a prompt sound, some things appeared in the long weapon like built-in lights. What's more amazing is that a projection-like sight appeared at the correct message. A light screen appeared at the sight of the rear seat, but Lin Bin couldn't understand 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 means safety, red means danger, that is, unlock it in the red position?"

The facts proved that Lin Bin's guess was correct. He touched the red position on the light screen, and then the guy in his hand gave another electronic sound prompt, and the trigger device that he had not seen before appeared.

A "boom" sound suddenly came from the square in the basement. Because it was the environment of a secret room, no matter how big the secret room was, the small noise would be increased.

"Is it a Gauss-like weapon?"

Yes, yes, Lin Bin had already pulled the trigger once, and the position of the target was the wall of the war equipment. A small crater appeared at the position where it was hit, but it was obvious that it did not break through.

"The materials science of this alien civilization is very powerful. This thing is another war weapon. The inability to penetrate individual weapons does not mean that the weapon is not powerful!"

Lin Bin originally wanted to take out other guys who looked like weapons to test them one by one, but a "bang" appeared again. He came out of the war machine and looked at the source of the sound. It was definitely not the gate that had "demon" before, but 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 attacked, and the scenes that continued to happen made his breathing become rapid, because more and more doors were being attacked!

"Seventeen, there are 'demons' behind the 17 doors!"
Chapter completed!
