Chapter 692 The Secret Hidden Behind the Wall

Li Wenxi looked around, her eyes a little solemn, and whispered: "They are all paying attention here, just wait a moment."

Everyone stood there and looked around cautiously.

Their eyes had begun to adjust to the scarlet surroundings.

But in the eyes of others except Li Wenxi, the movements of the small jellyfish around them had not changed much from before.

"Is it the sound of the laser gun that attracted the attention of those little mechanical jellyfish?" Wen Guixin whispered, "Yingying, you should have taken it out earlier."

"It's not that I don't want to use it." Xu Ying looked at the small sound-eliminating device in her hand and said with some worry, "Although this thing can cancel the sound, it may be discovered."

"Will he be discovered?" Zeng Tao whispered in surprise.

"Yes." Xu Ying nodded, "This thing relies on reverse sound waves to neutralize air vibrations, causing the sound to not be transmitted. This thing also emits some sound waves and electromagnetic waves."

She looked around: "In this place that is extremely important to alien invaders, I am afraid that they will have the ability to detect such abnormal fluctuations."

Everyone else looked around nervously when they heard this.

"Wen Xi, how are you?" Xu Xin asked in a low voice.

"...Their attention has begun to shift." Li Wenxi's voice relaxed a lot, and she said with some fear, "I almost attracted them because of the sound...Ah! Two small mechanical jellyfish flew over here. !”

Just as Li Wenxi said, two small mechanical jellyfish flying in different directions flew towards Xu Xin's location.

They glowed red under the red light, like two bombs about to explode.

It's quite oppressive.

"Let's hide for a while." Xu Xin whispered.

Everyone walked towards this small pothole.

The two small mechanical jellyfish found the position where they had just cut very accurately, circled the hole a few times, exchanged a few words with each other, and then left.

They did not see Xu Xin's group of people who were seven or eight meters away from them.

"Huh, it seems there's no problem." Li Wenxi breathed a sigh of relief, "The little mechanical jellyfish around us won't pay attention to this anymore."

Unexpectedly, the cutting sound is still an aspect that needs attention.

Xu Xin touched her chin and started thinking.

Everyone came to the pit again, and Zhao Xiaochuan jumped into the pit again.

With the help of the sound cancellation device, everything went smoothly this time, and the surrounding mechanical jellyfish did not notice this.

And Zhao Xiaochuan also started to cut like a welder "sssssss-".

In fact, the cutting sound is not loud, it can even be said to be very small.

But it was obvious that the surroundings were a little quiet.

"This cutting speed..." Wen Guixin said a little speechlessly, "With just this cutter, it is indeed a bit too slow."

"Huh? You're kidding, I'm already very fast, okay!" Zhao Xiaochuan retorted while slicing.

Zhao Xiaochuan's cutting can be said to be relatively fast. In just half a minute, a piece of scarlet crystal the size of a fist was cut out.

He put the scarlet crystal into his backpack and continued cutting.

However, at his speed, it might take some time to cut a hole in the scarlet crystal that can fit a small nuclear weapon.

Moreover, they not only have to cut in this place, not to mention they also need to go deep into the scarlet crystal and directly bomb the deepest part of the scarlet crystal.

According to Ji Chaoyang's prediction, they have less than ten hours left.

It takes ten hours to complete the task with just one cutter.

It seems that their idea just now was correct, and they must consider grabbing the three cutters used by the three alien invaders below.

"Yingying, how many of these little sound-eliminating props do you have?" he asked.

"This is the only one." Xu Ying looked at the small metal ball in her hand, "This thing uses technology from another time and space."

"Huh?" Wen Guixin was surprised when she heard this, "Can't you use things from another time and space? As long as you use them, you will..."

Xu Ying shook her head: "This thing just uses technology from another time and space, but it was made thousands of years ago when they were still there. I only have one in my hand, and I don't know how to make it, otherwise you would have mass-produced it long ago."

Xu Xin looked at Zhao Xiaochuan who was cutting scarlet crystal, and then at the numerous small mechanical jellyfish around him.

"If that's the case, then we have to find a way to lure away these little mechanical jellyfish around us, otherwise we won't be able to do many things."

"Lead them away? Shall we lure them away? It always feels so dangerous...ah!" Zeng Tao suddenly said, "That monster!"

Xu Xin nodded.

"It's time to let it out."

Zhao Xiaochuan raised his head and raised the cutter that was releasing a short laser in his hand: "Then leave this to me first. I can't use the cutter in my hand. It's a waste of time."

"Wang Lei, Jin Yue, you two stay with him." Xu Xin said, "The scene will probably be chaotic in a while, so you should be careful here."

"Okay Brother Xin, I understand." Wang Lei nodded.

"I understand." Jin Yue said.

Xu Ying handed the small sound-eliminating device to Jin Yue beside her: "This is for you, use it carefully. If there is any situation, stop cutting immediately and turn off the device."

Jin Yue took it: "Okay, how do you turn this on and off?"

"I teach you……"

The others glanced at each other, and Xu Xin nodded lightly.

Everyone slowly walked to the edge of the scarlet crystal.

Below, rows of black muzzles were facing them.

And the three alien invaders were still cutting the scarlet crystal like machines.

He was surprised to find the speed at which the alien invaders cut the crystal...

so slow.

Really slow.

It took them a long time to cut off a piece of scarlet crystal the size of a fingernail, and then carefully put it into a metal basket next to it.

At this time, only the bottom layer of the metal basket was covered by a scarlet crystal the size of a fingernail.

It may take a long time to fill up this metal basket.

"Why are they cutting so slowly..." Lou Fei'er whispered, "The cutters in their hands are not good, right?"

Xu Xin frowned.

It's possible.

Just now, Zhao Xiaochuan just turned his hand in a circle and dug out a fist-sized scarlet crystal from the wall.

But the alien invader fumbled there for a long time before getting out a piece the size of a fingernail.

This really raises the suspicion that there is something wrong with the cutter.

The cutter Xu Xin got was a cutter displayed by the alien invaders in order to speed up the cutting progress and select talents.

Therefore, the cutter in their hands is likely to be a specially optimized speed type.

...That's not right either.

If there is a specially optimized cutter, can it be used directly by the three alien invaders below?

What new workers will be selected?

Forget it, now is not the time to think about that.

"We have to find a relatively safe location to release it first," Xu Xin said.

"Do you want me to take you out first?" Xu Ying suggested.

"No." Xu Xin shook his head, "It must appear here directly to disrupt the situation here. If it appears outside or in other locations, it will only make the guards here more stringent and make it worse for us. Take action."

"Indeed." Xu Ying nodded lightly.

"That said, but... there is no safe place around here..." Wen Guixin looked around.

Basically, everything below is filled with black muzzles.

Moreover, if you look carefully, it seems that those forts are not moved from other places, but... grow directly in the roots of the World Tree that make up the ground.

The lower part of them is actually embedded in the root system of the World Tree.

It looks like they grew out of the ground on their own after learning of the crisis.

"There is still a way." Qin Fu raised his chin and said.

Indeed, on the ground dotted with forts, these forts gave way to a "path."

This road surrounds the scarlet crystal, forming a circle, and then branches and extends straight in one direction.

Everyone followed the "road" that was not occupied by the fort and looked in that direction.

There is nothing unusual, it is still an intricate wall composed of the thick roots of the World Tree entangled together.

If it weren't for this "road", they wouldn't think there was anything special about this wall at all.

but……

"Hey, that position...are the gaps between those roots a little bigger than other positions?" Li Wenxi suddenly tugged on Xu Xin's arm and whispered.

Xu Xin narrowed his eyes and looked over.

As Li Wenxi said, it is indeed true.

That small wall of World Tree roots seems to be...

The wall looks a little looser than other locations.

They are also all entangled with the roots of the World Tree. The roots in other locations are tightly intertwined, and that location...

Doesn't seem that tight.

But in fact there is a big difference.

It was to the extent that if it hadn't been for the road that made them notice the wall, they wouldn't have noticed it at all.

Who could find such a small, slightly loose spot among such a large wall of roots?

"It seems that the fort growing on the ground has helped us." Xu Xin said with a smile.

"Grown from the ground?" Zeng Tao looked at the ground and was shocked, "It actually grew from the ground!"

"Did you just find out..." Lou Feier said speechlessly.

"Okay, in that case, let's go over there and have a look." Xu Xin looked at the people around him, "Let's go together."

"good."

Everyone jumped down from the scarlet crystal and landed very lightly.

Fortunately, it did not attract the attention of the surrounding forts.

At this time, they were only four or five meters away from the three alien invaders who were working hard to cut away.

There were bursts of cutting sounds from over there.

From the sound point of view, it is no different from Zhao Xiaochuan's cutter. The sound is not loud and is almost exactly the same.

"Let's go, don't disturb them." Xu Xin whispered.

Everyone walked along this road without a fort, towards the edge of the underground space.

Because the underground space was not that big, just the size of a football field, they quickly reached the edge.

"Is this right here?" Zeng Tao stretched out his hand to touch the wall made of the roots of the World Tree. "It feels similar to the underground space of our World Tree... Why are you arresting me?"

Lou Fei'er grabbed Zeng Tao's hand that wanted to touch the wall.

Although Lou Fei'er's strength was definitely not able to stop Zeng Tao, Zeng Tao still stopped on his own.

"What do you think, can you touch anything here?" Lou Fei'er raised her hand and gave her a headache.

Zeng Tao covered her head: "Okay..."

At this time, several other people were trying to look inward through the gaps in these roots.

Xu Xin discovered that there was indeed a gap of about one finger between the entangled roots here.

But because the roots of these world trees are at least tens of centimeters or even more than one meter thick, this finger-width gap cannot be seen from a distance.

But up close, it can indeed be seen relatively clearly.

Compared to other locations where the fit is tight, or even partially deformed due to being too tight, this is indeed very different here.

From these gaps, Xu Xin could even hear the faint mechanical sound coming from inside.

"There is indeed something inside this." Xu Xin touched his chin.

"What could be inside this?" Wen Guixin said to herself.

"It should be the exit, right?" Qin Fu speculated, "This place must not be one that can only be entered but not exited."

Xu Xin nodded.

This is what he thinks too.

After the alien invaders carved the scarlet crystal from the inside, how did they take it out?

Do you have to jump more than ten meters high into the "rotating slide" above, and then spin up and climb up?

Although the physical abilities of alien invaders should not be a problem, it is really too troublesome.

So, there must be an exit here.

This should be it.

but……

How to open it?

"Try it by touching it?" Zeng Tao suggested.

"I'm sure it won't open if I touch it..." Li Wenxi said softly.

"Give it a try, there is no other way now." Zeng Tao looked at Xu Xin.

Xu Xin nodded.

Zeng Tao immediately reached out and grabbed the thick roots.

It really didn't work.

"I'll try harder!"

She inserted her finger into the gap as thick as a finger, and then began to exert force.

The roots were slightly deformed under her force, and they were opened from the gap of a finger to the gap of about a punch.

Everyone looked back and saw that the mechanical jellyfish and turrets had not changed much.

Zeng Tao had already used his greatest strength at this time, his face was turning red, and he was gritting his teeth and trying hard to break it.

"Okay, let go." Xu Xin patted her head.

"Well……!"

Zeng Tao immediately let go of his hand.

The entire root returned to its original shape the moment she let go.

"This is too difficult to open..." Zeng Tao said aggrievedly, rubbing her already red fingers.

Zeng Tao couldn't open it with all his strength, so what should he do?

"Otherwise, let's release it here." Xu Ying suggested, "It may not be safe here."

"But it's too dangerous here." Wen Guixin pointed to the densely packed forts around her. "Those forts feel like they can turn on us at any time. Once discovered, we will be blown to pieces."

Everyone pondered.

How to do it……

"Hey!" Li Wenxi suddenly exclaimed in a low voice, "Look, do they have an alien invader coming?"

Everyone looked around and saw one of the three alien invaders lifting the metal basket above his head and moving towards this side.

Are you really coming?

Xu Xin and others were surprised at first, and then happy.

Is it... just trying to get inside this wall? You should be able to open this place!

Everyone tacitly gave up this position and silently waited for the alien invaders to approach.

Soon, it moved here and stopped in front of the wall entangled with roots.

Then, something amazing happened.

This wall composed of thick roots of the World Tree slowly spread out in all directions like mutated vines!

These roots were received into the surrounding walls, revealing the scene behind the walls.

Xu Xin and others saw that the space behind the wall was not large, but very small, about the size of a bedroom. There was no passage to the outside world as they imagined. Instead, it was very high, nearly ten meters, equivalent to a three-story building. .

The most surprising and eye-catching thing among them is a huge machine, seven or eight meters tall, occupying most of the space!

The alien invaders move into the front.

Everyone looked at each other and followed him one after another.

Then, they discovered that the alien invader with the metal basket poured the dozens of fingernail-sized scarlet crystals in the basket that only covered the bottom of the basket into a small opening in the machine.

"Ka-ga-"

The machine made a sound, and the opening into which some scarlet crystals were poured slowly closed.

Then, the alien invaders put away the metal basket and returned the same way.

...This was originally the place where scarlet crystals were processed and preserved?

No one spoke or followed the alien invaders, but stayed here.

After the alien invaders left this small space, the roots of the World Tree that originally formed the wall gathered and entangled again, and the wall was formed again, locking Xu Xin and the others inside.

This small space became dark, and I couldn't see my fingers. The only light was the flashing red dot on the machine.
