At this time, Xu Xin's watch vibrated again. It was Li Wenxi calling.
Although it is not dawn yet, she is already preparing to go out mining with a large group of people.
"How's things going over there? I saw from the explorers that you said you've gone down and found some mechanism. It's not dangerous, is it?" Li Wenxi was a little worried.
"Don't worry, it's safe for us to come down together to explore this time." Xu Xin said with a smile.
"Well, you must be careful then."
Xu Xin was observing the surroundings while chatting casually with Li Wenxi.
She said that today she planned not only to dig iron ore, but also to take people to dig saltpeter and black gold.
Indeed, saltpeter is now needed to make explosive crossbows and heavy crossbows, and black gold ore is also the raw material for universal alchemical materials. These two ores are also indispensable.
"This is a huge burden for you. Why not let my beloved concubine and those two little guys help you? I don't know if they can enjoy your 100-fold explosion rate bonus." Xu Xin suggested.
"Yes!" Li Wenxi also thought of this, "Well, I'll take them to try mining this time!"
Aifei's mining speed is very fast, but without a high explosion rate, it may reduce the total output of a mine.
However, it doesn't matter. The world is so big, Li Wenxi can explore for minerals, and he can make convenient things like portals. The total production volume of a mine does not need to be considered at this stage.
At this stage, the priority is to improve mining efficiency.
"Okay, I'm leaving too, so you have to be careful too."
After hanging up the call, Xu Xin had already walked around the iron room.
The smooth iron walls and floors do not feel cold to the touch, but instead give people a faint sense of warmth.
That's right, he didn't pay attention when he touched the ground just now, but now he realized that the walls and floors here are actually a little warm.
Probably, the temperature is around 20 degrees.
The temperature radiating from the iron plates on all sides makes the inside of this iron room relatively warm.
Compared to the single-digit temperature outside, the temperature here is more suitable.
Moreover, it is worth noting that the gap between the wall and the iron plate in this iron room is not seamless.
Instead, a very tiny gap is left.
This made Xu Xin slightly alert.
He knew very well what this gap was used for.
Release the red mist!
That’s right, he was forced to climb up and escape in a panic because of the red mist released from this gap.
Since there is such a gap in this room, it means that red mist will also be released here.
Lou Feier had said before that there was a faint smell of red mist here.
He couldn't smell it.
"The sixth one has been found!" Lou Feier's surprised voice came over.
"Hmm!" Coco also let out a somewhat proud cry.
"Good job Coco!"
“Oh my!”
Xu Xin walked over.
At this time, Lou Feier was standing on a sinking iron brick. When she saw Xu Xin coming over, she walked out before the brick sank into place.
Then, she took out a stone from her backpack and placed it on the brick, then nodded with satisfaction: "Done! I turned on all the gravity machines and placed a stone on each one."
Xu Xin looked around.
Sure enough, a green-level stone was placed on top of every square brick he had stepped on before.
The green light emitted by these stones showed their locations before Xu Xin's eyes.
"Not bad... eh?" Xu Xin said softly.
"What's wrong?" Lou Feier asked in surprise when she saw him frowning.
"The location of these gravity mechanisms seems to... symbolize something." Xu Xin observed and pondered.
These six gravity mechanisms seemed to be at the six vertices of a hexagon, forming a circle at equal distances.
Xu Xin walked to the middle of the gravity mechanisms and reached out to touch the floor.
There are no hints.
Perhaps, something will appear only after the mechanism is triggered
"Hmm?" Coco ran to his side, tilted her head and looked at him, not understanding what he was doing.
Coco didn't find anything either.
It seems that he was overthinking it.
"Let's talk about it after they come down." Xu Xin picked up Keke, stood up, and looked at Lou Feier. "Where is the specific location of the thing that can make you stronger?"
"Hmm... I feel like it should be underground... Yes! It is underground." Lou Feier nodded with certainty.
Underground
"Perhaps, this mechanism is to open the passage leading to the underground?" Lou Feier guessed.
"Well, it's very likely." Xu Xin nodded.
At this moment, a faint sound was heard in the passage, which was picked up by his enhanced hearing.
"They are coming down." Xu Xin came to the entrance and waited.
"Huh? How did you know? Did you hear it?" Lou Feier also walked over and looked up, but couldn't see anything.
The two waited for another three or four minutes.
"Here they come! They are coming down!" Lou Feier had been staring at the passage and finally saw some figures.
Soon, the first person approached.
"Stay away!"
It was Wen Guixin's voice.
The two of them took two steps to the side, and Wen Guixin immediately jumped down from above and landed lightly on the ground.
Compared to Zeng Tao's way of hitting the ground with a "bang", Wen Guixin, who also has high combat power, is much lighter.
"Why are the others so far away from you?" Xu Xin was a little puzzled.
His ears could roughly detect the position of the person behind him, but he was too far away from Wen Guixin.
"Ah... um..." Wen Guixin said a little embarrassedly, "My poison can spread through the stairs, and Wang Lei was accidentally infected just now. I gave him the antidote and went down alone first, asking them to wait for a while before leaving."
“… That’s amazing.” Xu Xin’s mouth twitched.
It can actually spread through stairs!
Fortunately, it cannot be transmitted through the ground, otherwise it would be useless even if I stood close to her.
“You are so capable.”
"By the way, what on earth is this place? It's a long iron passage, and the ladder is so torturous that you can only climb it..."
Wen Guixin grumbled a little and looked inside the passage.
Although the people behind were far away, it only took two or three minutes.
Soon, everyone else jumped out of the passage and stepped onto the floor of the iron room.
As soon as they came down, they began to look around.
Xu Xin took them to try out the gravity mechanisms.
The mechanical and technological feel of the gravity mechanism amazed them.
"Hmm?" Coco suddenly let out a puzzled sound, raised her head and looked upwards, turning her little head and looking around.
"Is this space really a completely enclosed iron room?" Zhao Xiaochuan looked around. "The whole room is made of iron? Even this mechanism is made of iron. Is this really iron? It looks like iron, but it doesn't feel like a simple metal. It should be some kind of alloy, right?"
He reached out and touched the metal wall.
"It's very likely." Xu Xin nodded. "The passage above should be made of iron. After all, it is covered with rust. But this room..."
Xu Xin looked around.
The room was surrounded by smooth metal walls without any signs of rust.
The material of this room is obviously different from the above.
It probably wasn't iron at all, but an alloy, or a new metal.
"At this point, is there anything else worth being surprised about?" Wang Lei stood at the bottom of the passage and pointed at the passage above his head. "Such a long passage, all made of iron, how much iron must have been consumed? It's not normal that the room below is also made of metal... Hmm? WTF!
”
“Bing!” Keke also noticed something unusual and screamed. She pushed Xu Xin’s face with one paw and pointed the other one diagonally upwards, “Bing, ing, ing!”
Wang Lei and Coco's screams startled everyone else, and they looked in the direction they were pointing.
Then everyone's eyes shrank!
They saw that the exit of the passage above was slowly closing without them noticing!
A piece of iron plate moves horizontally from the side, like a sliding door closing!
It's already half closed!
Xu Xintong's eyes shrank.
The closure happened silently, without even a friction sound, and his enhanced hearing did not even hear it!
"Don't let it close!"
"Stop it now!"
Several people rushed over immediately.
Wang Lei, who was just below the passage, came to his senses immediately. Without saying a word, he grabbed the ladder and tried to climb up, hoping to use his extraordinary strength to prevent the iron gate from closing.
But it didn't work.
Because, the moment he climbed up the ladder, the iron gate seemed to sense something, and the originally slow closing movement suddenly accelerated!
"Bang!"
The iron gate closed suddenly with a loud noise.
The only entrance for people to enter and exit this iron room and underground space was completely closed.
The original passage exit on the ceiling has completely disappeared, and the ceiling has become very smooth.
If there wasn't a ladder left in the room, I'm afraid no one present would have been able to find the exact location of the exit.
"this… "
“嘤…” Coco lay on Xu Xin’s shoulder and put her little head close to Xu Xin’s face, feeling a little scared.
Both Wang Lei, who had just grabbed the ladder and had not yet had time to climb up, and the five people behind him were silent at this moment.
There was a solemn look in the eyes of several people.
They were actually locked in this closed room!
Lou Feier subconsciously walked to Xu Xin's side and looked around vigilantly.
"… It seems that we can only continue exploring." Xu Xin said in a heavy tone.
This room actually blocked their way back and prevented them from going up.
Is it because the number of survivors detected in the room is enough to activate the mechanism
Such mechanisms buried deep underground are absolutely extremely dangerous.
However, they were originally here to solve the problem of the formation.
Moreover, Area 188 should be relatively safe until the end of this cold winter.
So, even if a few of them disappeared for a while, it wouldn't be a big problem.
By the way, can the current watches still...
He was about to raise his watch to check, but Ji Chaoyang had already put it down and shook his head at him: "The communication of the watch has been interrupted. We can no longer contact the outside world."
"No way...!" Zhao Xiaochuan clicked his watch a few times and screamed, "I feel so uncomfortable. I feel like my watch is useless. It's like losing my cell phone in modern society. I feel uncomfortable all over!"
"Forget it now." Wang Lei swiped his watch twice. "There are not many people in this world who have watches, but they are still living well."
"I could have endured the darkness if I had never seen the light." Zhao Xiaochuan looked at his watch with a look of grief and indignation, and then his eyes lit up, "Oh? Although we can't contact the outside world, we can contact each other! Is this the local area network?"
A few people tried it and found that it was indeed the case.
That's not bad.
Wen Guixin swiped her watch twice and put it down indifferently. "Just solve it as soon as possible. Let's go and trigger the mechanism."
The people present were all strong men from District 188, who had been on the world rankings and had experienced many desperate situations, so they did not have much fear or terror about the current situation.
Although Zhao Xiaochuan screamed, he was just upset that his watch could not be used.
Ji Chaoyang was looking at the surrounding mechanisms at this time, with his brows slightly frowned.
"Let's replenish our body's amplification first, and then trigger the mechanism." Xu Xin said.
Now they have no choice but to trigger the mechanism first.
He still has a random amplification that he hasn't chosen, but after the mechanism is triggered, he will choose it based on the situation.
Everyone made up the status.
"Then let's go directly..."
"Wait a moment."
Lou Feier suddenly interrupted Wen Guixin, her expression a little strange: "Why do I feel that the smell of the red mist around me is getting stronger?"
The smell of red mist is getting stronger
Several people sniffed the air carefully.
"No?" Zhao Xiaochuan asked doubtfully, "I don't smell anything."
"Sister Fei'er has a mutant physique, so she must be much more sensitive to the smell of red mist than us." Wang Lei did not ask what the smell was, but scratched his head and said, "But what does this mean?"
When Xu Xin and Ji Chaoyang heard Lou Feier say this, they rushed to the wall of the room and looked towards the gap between the wall and the floor.
I saw that the gap, which was originally just a slight crack, was now a finger wide!
There was a faint red color lingering around the gap, and at the same time, they could already smell a faint fragrance!
That’s right, this is the fragrance that appears when the red mist is very light.
"Ah!" Coco cried and covered her little nose.
"Not good!" Both of them were shocked.
Xu Xin immediately turned around and said, "Quick, go and trigger the mechanism!"
Ji Chaoyang immediately ran towards the farthest mechanism and said, "The red mist is about to be released. Activate the mechanism quickly, otherwise the whole room will be filled with red mist!"
Lou Feier took action immediately.
"Ah? What do you mean?" The others were a little slow because they didn't know what Xu Xin and the others were talking about.
However, they saw the nervous expressions of Xu Xin and Ji Chaoyang, and immediately took action, running towards the mechanism!
Xu Xin had already stepped on the mechanism at this time.
But what shocked him was that this time the mechanism...
There is no response!
There was no "click" sound and no sinking.
Don't move at all!
What's going on
Wrong location
No, it's here!
"Why can't the mechanism be triggered?"
"Yeah, that's me too!"
There were some doubtful voices coming from the people behind me.
"Shh..." A slight sound of air releasing came into Xu Xin's ears.
This made his heart tighten.
"Hmm!
"Keke suddenly screamed, pointed at the gap in the corner, and pushed Xu Xin's face with her little paws.
He immediately looked towards the gap between the wall and the floor.
There, no red mist has been released yet.
But the voice he just heard was definitely true!
"The smell of the red mist is getting stronger!" Lou Feier said at this time, "I can already feel that my strength is increasing!"
"What the hell is going on? Is this the red mist that made mutants stronger during the previous event?" Wen Guixin asked in surprise, "Are we... being locked up and deflated?"
Damn, what should I do
Ji Chaoyang also frowned.
Although it is unclear what harm this red fog will do to the survivors, but...
The smell alone is enough to make people faint!
"Squeak—"
At this moment, thick red mist suddenly gushed out into the room from the gaps around it!
The smell around quickly changed from a faint fragrance to a strong aroma, and then turned into a foul smell!
Several people's faces changed, and they covered their mouths and were about to retch.
This smells so bad!
Xu Xin glanced at Lou Feier.
Although she was nervous at the moment, her face showed a slight excitement.
Because of his request, the time Lou Feier could enter the red mist room was limited to half an hour every day, for fear that she would have mental problems. After all, red mist was not a good thing.
But because of this, she couldn't enjoy herself every time.
So when she learned that she could inhale the red mist here, her body even showed some symptoms of addiction.
Xu Xin looked at her and his eyes lit up slightly.
That’s right!
Lou Feier is not afraid of the red fog!
"Come here! I have an idea!" Xu Xin said immediately.
He took off the bracelet on his hand and handed it to Lou Feier, who ran over immediately after hearing his words.
“Huh? Ah…!” Lou Feier opened her eyes, immediately understood what Xu Xin meant, and took the bracelet.
"Let Lou Feier put us into the bracelet. She will stay outside. When everything is fine, let her let us out!" Xu Xin immediately explained to the others around him.
"Won't you lose your sanity in the red fog?" Ji Chaoyang asked Lou Feier.
Lou Feier immediately shook her head: "No, don't worry, even when my mental strength was very low before, I didn't lose my sanity, I just saw some hallucinations."
At this time, the red fog around them was about to spread and surround them!
"Hmm... Let's go in first. We can't be surrounded by this red fog. If we are surrounded by the red fog, we won't mutate!" Wen Guixin covered her mouth and nose and said quickly.
Xu Xin nodded to Lou Feier, who immediately took the bracelet and touched Wen Guixin with it.
Wen Guixin immediately agreed and entered the bracelet.
Fortunately, I was not infected through the bracelet.
So, she took everyone else in.
"Use the watch to contact." Before being taken in, Xu Xin pointed at his watch and disappeared into the room.
The moment he disappeared, red mist completely occupied the entire room.
Lou Feier was also completely buried in the thick red fog.
She took a deep breath, a relieved expression on her face, a red glow in her squinted eyes, and two blood lines crept up her cheeks.
"Huh... The density of this red fog is just like this, not even as high as the one in the cabin."
She murmured to herself, then took another deep breath and smiled with satisfaction.
