Chapter 684 The Voice of the Alien Invaders

Xu Xin looked around at the strange alien invaders in all directions.

This scene would definitely scare most people into fainting.

Thinking of entering this group, he felt his scalp numb.

If it weren't for the cloak of the Invisible that gave him a certain amount of confidence, he would really want to turn around and go back now.

He turned slightly and looked behind him.

The long corridor behind him suddenly appeared in the entire inner space of the World Tree, like a one-kilometer-long train body.

Within the entire World Tree, this corridor, which looks like a train body, is the only thing that can be called a "building". The rest of the place is flat.

On both sides of the corridor, there are also many alien invaders "setting up stalls".

Unexpectedly, when they were walking in the corridor just now, there was only a wall, only a few meters away from the alien invaders.

At this time, Lou Fei'er gently came to his side.

Xu Xin looked at her with questioning eyes.

She opened her cloak slightly, and Coco slipped out of her arms with a swish, and was instantly in Xu Xin's arms.

Xu Xin suddenly broke out in cold sweat on his forehead.

He looked around slowly.

Fortunately, no one around them noticed their presence, and the alien invaders were still immersed in their market.

Xu Xin breathed a sigh of relief.

At this time, Li Wenxi beside him gently pulled his arm.

Xu Xin looked at Li Wenxi and saw her looking at the corridor behind them with a look of fear.

Xu Xin looked towards the corridor again.

He couldn't help but take a deep breath through his nose.

I saw the originally wooden corridor behind me slowly slowly...

Become transparent!

The originally wooden corridor has become like glass, and the situation inside can be clearly seen from the outside!

The alien invaders' group was also attracted by this change for a few seconds.

Of course, because they have eyes all over their bodies, they don't need to turn around to look like humans do. Instead, they seem to straighten their dark bodies, and their eyes widen as they face the transparent corridor.

Xu Xin and the others were not far from the entrance of the corridor, and the eyes of these alien invaders were staring directly at them.

There was no cover in all directions, and the only cover, the corridor, was transparent, causing them to directly bear the gaze of all alien invaders from all directions.

Li Wenxi's hand tightened on his arm.

Lou Fei'er and Jin Yue both came to their sides and looked around cautiously.

Fortunately, the alien invaders' gaze did not last long.

They seemed to have become accustomed to the changes in the corridor. They just paid attention here for a second or two and then returned to their original state.

It seems that this kind of thing is commonplace and common, so it is not worth paying attention to.

The four of them breathed a sigh of relief.

Xu Xin looked around again, her eyes stopped at the crack of the open door of the corridor, and saw the inside of the corridor.

Huh……?

He didn't look there on purpose.

After all, the entire corridor is transparent. Even if you don't see through the door crack, you can still see the inside. Generally speaking, you don't pay attention to the door crack.

But the situation in front of me is different.

Because Xu Xin discovered that looking in through the crack in the door, one could still see the completely opaque, dark red wooden wall with growth rings.

In the completely transparent corridor, only the crack in the door was not transparent, which of course caught his attention.

His expression changed slightly.

What does this mean?

This shows that although the corridor is transparent when viewed from the outside in, it is still opaque when viewed from the inside out!

In other words, people outside can see inside, but people inside cannot see outside.

Judging from the reaction of the alien invaders just now, this kind of change is actually very common. It is so common that they look here and don't care.

... Could it be that when they were walking in the corridor just now, the corridor was also transparent?

Li Wenxi and the others also noticed this situation, and they all showed a little fear.

It turns out that they were not safe at all when they were walking in the corridor just now. They could be seen by the alien invaders outside...

No wonder there is not even a camera in the corridor, it is empty, because there is no need to install it, because the outside can directly see inside!

From this point of view, the difficulty of infiltrating this World Tree is simply hellish...

Even if you know how to get in, you think no one has discovered it after you get in, but you have been watched over and over again by hundreds of alien invaders...

It would be completely impossible for other alien invaders to sneak into this place.

Xu Xin's face showed a slight bitter smile of surviving the disaster.

Zhao Xiaochuan's Invisible Cloak saved them too many times without realizing it.

This thing is absolutely invincible when sneaking in, and it performs its role perfectly.

Thinking about it, this is the World Tree that has existed for nearly a thousand years. It is the base camp of alien invaders. How can it be so easy to sneak in?

That means they were lucky, otherwise they would have died on the spot as soon as they entered.

After thinking about this, Xu Xin relaxed.

Since they were not discovered in such a terrifying surveillance corridor, it has confirmed the super effect of the cloak of the Invisible.

They don't need to be too nervous.

"Hey..." Coco was in Xu Xin's arms, with her little head half out and her little paws half out, pointing in one direction.

Coco is giving him directions.

Over there is the most densely populated area of ​​​​this "market".

There are many alien invaders "setting up stalls" and alien invaders operating freely.

Xu Xin calmed down and gestured to the three women around her, indicating that they should go that way.

The three women all nodded slightly.

Just when Xu Xin was about to take the first step, suddenly, above his head, the small mechanical jellyfish wandering in the air started to move.

Some of them suddenly changed their flight direction and began to fly towards them!

this……!

Several people's expressions changed immediately.

what happened? !

Discovered?

No, it's impossible. They haven't done anything yet, how could they be discovered.

Xu Xin reacted immediately.

These little mechanical jellyfish should be heading towards the corridor behind them!

Because they are still at the exit of the corridor!

Xu Xin grabbed Li Wenxi's arm and slowly walked towards the side of the corridor.

Lou Fei'er and Jin Yue also followed closely behind.

Just as a few people made way for the exit, dozens of small mechanical jellyfish had already flown in and nimbly got in through the gap in the already transparent door of the corridor.

One after another.

Xu Xin saw that the small mechanical jellyfish that had penetrated were flying quickly towards the end of the corridor, which was the entrance to the World Tree.

It seems that although the first batch of small mechanical jellyfish that entered did not find Xu Xin and the others, the managers of World Tree probably thought that someone had come in.

But because this passage cannot hide people at all, the managers here do not think that the intruder has come out of the passage, so they once again sent a small mechanical jellyfish to enter from the exit and intercept it.

It's a pity that they don't know that the intruders have already passed through this corridor under their noses and entered the interior of the World Tree.

Although the other party paid great attention to the inexplicable disappearance of the intruder, Xu Xin was still slightly happy in his heart.

Because they focused all their attention on the corridor, Xu Xin and the others who had already come out and were about to blend into the "market" were much safer.

Of course, this safety is certainly temporary.

If nothing is found in the corridor, they may begin to suspect that the intruder has infiltrated the "bazaar".

Therefore, they must move quickly.

Xu Xin winked at the three girls and walked towards the market without stopping.

He walked very slowly, one step, two steps.

After seeing little reaction from the alien invaders around him, he gradually quickened his pace.

Soon, he returned to his normal walking speed.

Still hasn't been discovered.

He did not continue to speed up, but just walked into the lively "market".

The three women followed closely behind.

A large area here is a "bazaar".

Although lively, it is not crowded.

After all, this area is very large, and the number of alien invaders is only about a thousand.

Although it looks like they are everywhere at first glance, the density is not high and people are not crowded enough to come into contact with each other, so Xu Xin and the others are considered safe.

At this time, Xu Xin was already standing in front of the stall of an alien invader "setting up a stall".

On the stall in front of it, there were dozens of scattered things, which looked strange.

There are unknown metals, weird biological specimens, strange handicrafts, and some tools that I don’t know what they are used for.

In Xu Xin's identification ability, only the unknown metal mine emitted a golden light, which was obviously a high-quality metal, while other things did not emit any light.

I don’t know if it’s useless or if I can’t identify it.

As for Magnet, behind the booth, an alien invader with bumps and eyes all over his body was sitting on the wooden ground.

In fact, whether the alien invader is sitting or standing, he looks like a puddle, with no body structure visible at all.

But the standing alien invaders, such as the alien invaders currently wandering around, are obviously much taller than the alien invaders in front of the stall, so Xu Xin believes that the "stall owner" in front of the stall It's sitting.

The sitting "stall owner" was completely unaware of the arrival of Xu Xin and the others, and even most of his eyes were closed, with only a few scattered ones still half-open, looking like they were Take a nap.

Just in time to test what they can do now.

"cough……"

Xu Xin suddenly cleared his throat and made a little sound.

This cough frightened Li Wenxi next to him. She stared at him with wide eyes, grabbed his arm, and blinked crazily at him.

This is in front of alien invaders!

Only one or two meters away from the alien invaders!

Lou Feier and Jin Yue were also frightened.

Among the group of alien invaders, their spirits have always been highly tense, but Xu Xin suddenly made a voice!

Xu Xin squinted her eyes and looked at the alien invader in front of her.

【Sleepy……】

【...No...come...meaning...】

He had already activated his mind-reading ability at this time.

As long as he has not experienced time travel, he can more or less read some voices.

None of these alien invaders have experienced time travel, so they can hear their voices to some extent.

But unfortunately, perhaps because the nervous system of the alien invaders is so different from that of earth creatures, although he can listen to some voices, he cannot fully capture what the alien invaders are thinking.

I could only capture some intermittent words, and I couldn't even piece together the general meaning.

But it was enough, at least Xu Xin could hear the fluctuations of emotions from the intermittent voices of her heart.

At least the alien invader in front of him didn't pay attention to his cough just now.

Can they speak quietly?

"...Ah, hello?" Xu Xin whispered.

Then he felt a slight pain in his arm.

It was Li Wenxi who pinched him gently.

Li Wenxi's little face turned pale with fright, and she quickly pinched Xu Xin to shut him up.

But she didn't dare to use force, fearing that the force would make Xu Xin cry out in pain, and that would be the end of it, so she only dared to pinch lightly.

Lou Feier and Jin Yue also stared nervously at the dozing alien invader in front of them.

The monster once said that human voices are very, very unpleasant to alien invaders, similar to the sound of human nails scratching a blackboard.

So, if the alien invader in front of him could hear his voice, he might wake up.

The alien invader did indeed half-open his eyes at the moment Xu Xin spoke, frightening the three girls Li Wenxi.

But it does have some doubts at this time.

[Why...is this...uncomfortable? 】

【how do I……】

【sick……? 】

Xu Xin tried hard to read the voice of the alien invader in front of her.

After a simple analysis, he understood.

The alien invader in front should be able to hear his voice.

But like his body, his voice was ignored.

It's like, a person who is engrossed in playing games at home will not care about what the aunt downstairs is talking about outside the window.

But despite this, his voice really reached the ears of the alien invaders.

This was an extremely unpleasant sound for an alien invader, and it made the "stall owner" in front of him feel uncomfortable.

It didn't know where its discomfort came from, and began to wonder if it was sick.

The corner of Xu Xin's mouth curled up into a slight smile.

It seems that they can still talk.

As long as you keep your voice down, there should be no problem.

Xu Xin took the three girls to a place a little further away.

"We can talk now." Xu Xin whispered.

His sudden words shocked the three women again, and they hurriedly looked at the alien invaders around them.

Fortunately, no alien invaders are paying attention here.

But the alien invaders have eyes all over their bodies and can see in all directions, so there is an illusion that all alien invaders are paying attention to them.

This is why Li Wenxi and the others are so nervous.

Being watched by so many alien invaders with terrifying appearances would make anyone nervous.

Only people like Xu Xin, who can read the voices of some alien invaders, can feel confident.

"Really...really?" Li Wenxi chose to believe what Xu Xin said and whispered.

Still not discovered by the surrounding alien invaders.

"That's it..." Xu Xin explained her guess.

"I see... Then we can indeed communicate in a low voice." Lou Fei'er also whispered, "Great, I have held back a lot of things to say. The first thing is... what on earth is this place?"

Xu Xin rubbed the head of the little guy who had been shrinking in his arms and didn't dare to show his whole head: "I'm afraid we have to ask Keke. He insisted on us coming in."

"嘤..." Coco's little ears moved and stretched out her little paws, "嘤..."

Coco's screams have become quieter, and she no longer wants to get out and run around by herself.

It seems that it is also starting to be afraid of the monsters around it.

"That's the situation. My appraisal ability can detect the quality of the things on those stalls. There are a lot of good things in them." Xu Xin whispered, "The things Keke wants us to find should be in there too."

"But, how are we going to take away the things on the stall?" Jin Yue whispered, "If it is a human, we can take it away secretly while the other party is not paying attention, but the alien invaders..."

The alien invader has eyes all over his body and can see in all directions. Unless he is as sleepy as the stall owner just now, there is no way he can take advantage of him without paying attention.

"The cloak of the Invisible, and...the space bracelet."

Xu Xin explained in a low voice.

The Invisible Man's Cloak does more than just make the person wearing the cloak disappear.

As long as anything is wrapped in a cloak, its existence will disappear, such as Coco in Xu Xin's arms, and the clothes Xu Xin is wearing.

These external things can still be hidden.

"Wrap an item with a corner of the cloak so that the weapon's presence disappears, and then put it directly into the bracelet." Xu Xin whispered, "This method may be feasible."

Li Wenxi and the three girls looked at each other for a few times, and then they all nodded.

At present, this should be the most appropriate method.

Xu Xin sighed in his heart.

I feel that this kind of thing should be done by Zhao Xiaochuan. He should be the best at it. He doesn't need to be wrapped in the cloak of the Invisible, as long as he reaches out and touches it.

Even if he directly picks it up and shakes it twice in front of the other person's eyes, the other person will not notice.

It's a pity that Zhao Xiaochuan is with Xu Ying and Wen Guixin.

"Then, let's take action immediately."

Xu Xin glanced at the corridor.

The corridor returned to its opaque state at some point, and the situation inside could no longer be seen.

But none of those little mechanical jellyfish came out of it, and they were even continuing to drill in.

...We must hurry up.
