"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... well..." 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.”

"Speaking of which, what exactly is this place? It's a whole long iron tunnel, and the ladder is so torturous that you can only climb it..."

Wen Guixin grumbled a little and looked up into the passage.

Although the person behind was 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.

They were amazed by the mechanical and technological feel of the gravity mechanism.

"Hmm?" Coco suddenly let out a puzzled sound, looked up, turned her little head and looked around.

"Is this space really just a completely enclosed iron room?" Zhao Xiaochuan looked around. "The entire room is made of iron? Even this mechanism is made of iron. So, 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 metallic wall.

"It's very likely." Xu Xin nodded. "The passage above should be made of iron. After all, it's 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's probably not 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, made entirely of iron. How much iron must have been consumed? The room below is also made of metal, isn't it normal... Huh? Holy crap!

”

"Bing!" Keke also noticed something unusual and screamed. She pushed Xu Xin's face with one paw and pointed the other upwards, "Bing!"

Wang Lei and Keke's screams startled everyone else, and they looked in the direction they were pointing.

Then everyone's holes 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 was silent, without even a friction sound, and his hearing enhancement did not even hear it!

"Don't let it close!"

"Stop it!"

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 wanted 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 suddenly closed 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 found the exact location of the exit.

"this……"

"Hmm..." Keke 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 out and prevented them from going up.

Is it because the number of survivors detected in the room is enough to activate the mechanism?

These mechanisms buried deep underground are 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 they disappear for a while, it’s not a big problem.

By the way, can today’s 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 watch's communication 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 phone in modern society. I feel uncomfortable all over!"

"Forget it." Wang Lei swiped his watch twice. "There are not many people in this world who have watches, and they live well."
