Lou Fei'er took one step ahead of Xu Xin and couldn't wait to enter the passage.

It seemed that there was indeed something down there that was attracting her.

Xu Xin also climbed down the ladder.

"If there is any situation, please contact us. We have been waiting at the entrance of the cave." Ji Chaoyang pointed to his watch and said.

Xu Xin nodded and climbed into it.

Lou Feier has climbed down more than ten meters.

Climbing very fast.

"Slow down!" Xu Xin scolded.

Climbing so fast, if there is any mechanism...

Or is it that this guy is relying on his extra life and is not afraid of death at all?

It would be really nice to have one more life.

The sound spread along the passage to the depths of the passage.

"Ugh!" Coco was startled.

Xu Xin felt a little regretful.

I shouldn't have called this, it would be bad if there was something down there.

"Oh." Lou Fei'er immediately slowed down her movements, waiting for Xu Xin to catch up, "Hurry up, hurry up, I feel like there should be something down there! Something that attracts me very much! I feel like that thing should be able to

Make me stronger!"

oh?

Make her stronger?

Xu Xin's eyes lit up slightly.

"Isn't it Red Mist?" he asked.

"No, it's something else. The red mist here is too thin and has no effect on me." Lou Feier said as she climbed down.

It's not red mist, but it can make mutated creatures stronger...

He thought of the radiation stone from back then.

It was that stone that allowed Mimi and Silver King to become intermediate mutant creatures.

After that, it also completed its mission and was completely shattered.

Perhaps the following thing is also such a thing?

"Keke, can you feel what's down there?" Xu Xin asked Keke who was lying on her shoulder.

"Ugh." Coco shook her little head to express that she couldn't feel it.

At the beginning, Coco did not sense the radiation stone.

It was Xu Xin who asked Ah Fu, who was unconscious at the time, to fly up and find out.

Maybe it's really a good thing.

If he could still find that kind of thing, then the people and beasts around him would benefit from it.

The two quickened their pace and climbed downward.

Lou Fei'er is not afraid of death, so she is very fast.

Xu Xin took the lead, so she didn't need to be so cautious and climbed down quickly.

"This passage is so long." After climbing for about ten minutes, Lou Fei'er sighed, "I thought I would be able to reach the bottom soon, but didn't I expect it to be so long?"

"Ugh!" Coco yelled in agreement.

"I don't know how long I climbed at the time, but it must have been more than an hour." Looking back on the experience, Xu Xin can still feel the horror and exhaustion.

Climbing down is the next best thing. Climbing up and being chased by the red mist really almost caught up with me.

However, Lou Feier should not be afraid of such a situation.

After all, Red Mist is a good thing for her.

"Ah? Then we won't have to climb for more than an hour, right?" Lou Fei'er stopped and glanced below, but it was still bottomless.

"If you still want to be the same as last time, then there is no need. This climb is much faster than the last time I climbed." Xu Xin said to Lou Fei'er below, "What are you stopping for? Continue."

"Oh, that's good. By the way, did Coco have the same experience last time?"

"嘤嘤!"

The two continued to climb down.

After climbing again for about fifteen minutes, Xu Xin's watch vibrated. He stopped and raised his hand to see that it was a message sent to him by Ji Chaoyang.

There is still signal for the watch in the channel, which is good.

"What's going on down there? Are you still climbing down?"

Xu Xin replied in voice as she climbed: "That's right, we haven't climbed to the bottom yet. However, this passage should be the same as last time and there is no danger."

"...How about we go down now? The three of them are a little anxious."

"We should hurry..."

"Ah, I saw the bottom!" Lou Fei'er suddenly shouted in surprise, "There are only a few hundred meters away! We'll be there soon!"

Xu Xin also looked down, and sure enough, not far below, the metal bottom could already be seen.

Below, there seems to be an iron room just like last time.

After climbing for so long, I finally reached the bottom!

Lou Fei'er's voice was also heard over there, and several people exclaimed.

"We'll go down right away to observe the situation. You guys wait a few more minutes."

"good."

After hanging up the call, Xu Xin and Lou Fei'er quickly climbed down.

Soon, Lou Fei'er stepped on the iron floor first and took two steps forward. Xu Xin also jumped down.

The moment he jumped down, Coco jumped off his shoulder with a "squeak" sound.

"This is... an iron room?" Lou Fei'er was a little surprised, "A completely iron room?"

Xu Xin had already expected this, so he wasn't too surprised.

He has seen such an iron room twice.

The first time was at the entrance to the underground world.

There was a skeleton in that room, with a line of unknown meaning carved on the back of the skeleton, and an iron door that could be opened. When he walked out of the door, he saw the underground world for the first time.

The second time, it was at the giant head.

In that room, they obtained information about the giant's head.

But here...

"What..." Lou Fei'er was a little disappointed, "There's nothing here? It's just a basement?"

That's right, there is nothing here.

A room that looks like an iron box.

The size of the room was huge, bigger than the two iron rooms he had seen before, and much bigger!

The height should be at least seven or eight meters, and the area should be at least four to five hundred square meters.

It is much larger than the previous two iron rooms with a height of four to five meters and an area of ​​only a hundred square meters.

But there is a problem with this iron room.

The space is too wide.

It was so spacious that except for the entrance above their heads, the entire iron room didn't even have a door!

A completely closed space.

It's like an iron box with a straw inserted into the mouth.

"Is this...is this a basement?" Lou Fei'er looked around, but still found nothing, "Who is so free! Buried the basement so deep! Ah!"

She turned to look at Xu Xin: "Did you get the gold treasure box from this basement? Isn't this really a dead end?"

Xu Xin frowned and said: "It was indeed such a room back then, but it had a door."

"Door?" Lou Feier looked around, "Where is there any door? Is it a secret door?"

"No." Xu Xin shook his head and said, "It's a very heavy door like a safety door. Only after I left this room did I find the gold treasure box."

Lou Fei'er has already begun to try to feel around on the wall: "Then it should be possible to get out of this room, right? I can feel that the thing that can make me stronger is very close! Maybe,

As long as you get out of this iron cube, you can find it!"

Outside the room...

It should be that world outside.

But why doesn't this room have a door?

"嘤嘤!" Coco suddenly shouted in the distance, "嘤嘤!"

Xu Xin looked towards Coco, who was standing in a position waving its little paws at Xu Xin.

That means obviously letting it pass.

"What's wrong?" Lou Feier also looked over.

"You first check the wall to see if there is a secret door." Xu Xin said as she walked towards Coco.

"okay."

Xu Xin walked to Coco's side.

Coco's current location is in a corner of the room.

But there is still nothing here.

The walls, floor and ceiling are all smooth and rust-free heavy iron plates.

"What's wrong?" Xu Xinke hugged her and asked.

"Hey!" Coco pointed her little paw at the floor.

"Floor?" Xu Xin squatted down and reached out to touch the floor.

Then his expression changed.

Because, a sound sounded in his ears.

[Survivor Gravity Mechanism: Survivors can trigger the mechanism by standing on it. There are six mechanisms in this room. After all the mechanisms are triggered, something will happen. 】

Xu Xin was shocked.

This is actually a gravity mechanism?!

Moreover, are there actually six mechanisms in this entire room?

In other words, six survivors are needed?

It just so happened that six of them were supposed to come down.

He pressed the floor with his hand, but nothing happened.

He stood up and stepped on it directly.

"Card!"

There was a clicking sound under the feet, and then, a square gap appeared on the surface of the originally smooth iron floor, and a 1*1 brick began to sink slowly under the feet.

"What's wrong?!" Lou Fei'er heard the sound and ran over immediately, "The floor has sunk in?!"

"It's okay." Xu Xin stopped her from trying to pull out her hand.

The sinking speed is very slow, and Coco has no reaction, so there should be no danger.

Moreover, the introduction also said that all six mechanisms must be triggered for anything to happen.

While the floor was sinking, Xu Xin told Lou Fei'er about the gravity mechanism.

"Something happened..." Lou Fei'er was also stunned, and then said, "Then I'll find the locations of the other ones!"

"Gene Era"

"Don't go to such trouble, Coco, can you find the location of the other ones?" Xu Xin rubbed Coco's tail and asked.

If there is no cocoa, someone may need to step on all the surrounding ground to find these six locations.

If there is a stuck sound, it means you have stepped on the right place.

It's not difficult to find.

But with Coco here, it’s even easier.

"Hey!" Coco jumped down from Xu Xin's shoulder and ran in one direction. Lou Fei'er immediately followed.

At this time, there was another clicking sound under the feet, and the iron block below also stopped sinking.

Probably, it sank twenty centimeters.

At this time, countless lines of blood-red light appeared on the sunken square meter, which shocked Xu Xin.

Fortunately, this is just a texture.

On the entire surface of the iron bricks, the flow shimmers.

Well, it feels like alien technology.

But think about it, isn't this real alien technology?

Xu Xin walked out of this small pit, and the bright lines on the entire square immediately dimmed, and then began to slowly rise.

Xu Xin stepped on it again, and the block began to sink again.

He thought for a while, called the Silver King out of the bracelet, and then let it step on the square.

"Ouch...?" Silver King was so big that he could only curl up on the block and looked at Xu Xin with a puzzled look on his face.

Its weight is much heavier than Xu Xin, but it does not prevent the cube from floating up.

Silver King cannot trigger the mechanism.

It seems that this mechanism is just like its name, [Survivor Gravity Mechanism], which must be triggered by survivors, and others cannot.

He immediately contacted the people above and told them the following situation.

"Is this really the case?" Ji Chaoyang thought about it.

"What are you going to do? Come down? Or should I go up directly?" Xu Xin asked.

"Of course we're going down!" Zhao Xiaochuan's voice came, "Of course we have to participate in such an interesting thing, Brother Xin!"

"Yes, you've come here, there's no need to go back. Didn't you say at the time that the golden treasure chest was found in a place like this? Then after triggering the mechanism, there must be good things there." Wen Guixin's voice was a little excited.

.

"Since there is no danger, let's go down now, Brother Xin," Wang Lei said to Ji Chaoyang's watch, "Hey, we are really overly cautious. We might as well go down together before."

"Well, let's go down there." Ji Chaoyang also said, "First find the six locations down there, and then see if you find anything else."

Regardless of whether the mechanism is activated or not, they must at least come down and take a look.

"Okay, then you should come down as soon as possible."

After hanging up the call, Xu Xin looked around the room again.

Outside the room, could it be the underground world?

What will happen after the mechanism is triggered?
