Chapter 682 The Horror Behind the Door!

The wooden door opened, and three small machines flying in the air flew in from outside the door.

These small machines have a flat elliptical shape and are red and white in color. There are several thin, leg-like mechanical limbs floating below.

It looks like a few mechanical jellyfish floating in the air. It is not big in size, not counting the mechanical limbs below, it is only about the size of a bowl.

It's exquisite, even a little cute.

"--beep--beep--"

"La-um-ka-"

The three small machines obviously paused after entering the door, then made a sound that Xu Xin and the others could not understand, and then started wandering around in the empty wooden house.

"——Beep-beep-click——"

"——Wow——Laka——"

Three small jellyfish-like machines came to a standstill in the center of the room. One of the small machines spun around a few times, and the mechanical limbs below them that looked like jellyfish streamers began to flutter.

"——Crash——?"

"Shaka - Raqqa -"

Now Xu Xin finally understood.

These small machines make sounds and it turns out they are communicating with each other.

They were probably discussing the situation in this room at this time.

With a little guessing, you can figure out what these little mechanical jellyfish are talking about.

"The World Tree should have brought some life here just now."

"Why is this place empty?"

This is probably what we are discussing.

With the cloak of the Invisible, even machines cannot detect them.

Xu Xin was even a little curious. If the current scene was recorded by a camera and someone watched the replay, would they be able to spot them?

Look carefully, there are some small cameras hidden in the corners of this wooden room, which can record members who enter the World Tree from outside the World Tree at any time.

Xu Xin, Li Wenxi, Lou Feier, and Jin Yue all leaned against the wall without saying a word, minimizing their presence.

Coco even more obediently nestled in Xu Xin's arms, huddled up and motionless.

And the three small mechanical jellyfish began to wander around in the empty wooden hall.

"Beep-beep-beep-wow-"

"Kala - Hu - Zhi -"

The hum of machinery echoed in the wooden hall.

At the same time, a small mechanical jellyfish floated towards the wall they were leaning against.

Getting closer and closer until he was only half a meter away from Xu Xin.

The mechanical streamers of the small mechanical jellyfish stretch out in all directions, like a detector, seeming to be detecting traces around it.

The little jellyfish came closer to Xu Xin again, only about twenty centimeters away from him.

Xu Xin didn't dare to breathe, and even held her breath.

This is too close!

Could this little mechanical jellyfish have discovered them?

Beside him, Li Wenxi looked at him with wide eyes, full of panic, but he did not dare to speak.

This is inside the enemy's World Tree, and Xu Ying is not with them. Once discovered, it is basically over, and there is almost no possibility of survival.

Lou Fei'er had already grasped the dagger at her waist, and Jin Yue began to gain momentum.

They were all afraid that the jellyfish would harm Xu Xin. In that case, even if they were discovered, they would still have to take action.

However, when the little robot was twenty centimeters away from Xu Xin, it stopped approaching and started spinning in the air again.

The mechanical limb below fluttered as it rotated, almost grazing Xu Xin's face!

Xu Xin felt cold sweat break out on his forehead.

At the same time, I felt a little aggrieved.

In fact, this little robot doesn't look strong at all. With the weapons in their hands, it is not difficult to destroy these three small mechanical jellyfish on the spot.

But the difficulty is that these three are robots, and there are cameras in this hall.

The three small machines are probably connected to some central system, and cameras are watching their every move.

Once a small robot is scrapped, an alarm is likely to sound in World Tree, which will make their situation more dangerous and may even make it difficult to move.

Therefore, these three little robot jellyfish may seem weak, but you must not take action against them.

The rotation of the little robot jellyfish in front of me stopped, and then a small screen on its "jellyfish head" flashed slightly.

"Beep-kaka-wow-"

The little mechanical jellyfish stopped dangling in front of Xu Xin's eyes and slowly left this position.

Xu Xin's Adam's apple rolled and he breathed a sigh of relief slowly.

...it seems to be okay.

The little mechanical jellyfish came here to search. It should have left some subtle traces on the ground here when a few people came up.

However, even if it checked, it could not find the four Xu Xin people right in front of it.

Zhao Xiaochuan's Invisible Man's Cloak is really an artifact... Xu Xin couldn't help but sigh in her heart again.

On the side, Li Wenxi's expression also relaxed, and Lou Feier and Jin Yue also took their hands off their weapons.

All four people broke out in a cold sweat.

It was too close just now. If you get even one centimeter closer, the mechanical streamer of the mechanical jellyfish will hit Xu Xin's face!

"Beep--"

"Wow--"

The three jellyfish gathered in the center of the room again, making a short sound.

Then they all flew towards the open door.

The four of them, Xu Xin, just watched three small mechanical jellyfish fly out of the wooden door.

And the door did not close after they left, it was just open.

The four of them finally relaxed this time.

"Oh my God..." Li Wenxi grabbed Xu Xin's arm and said in a low voice, "That little jellyfish just now almost touched you!"

"It's really thrilling..." Xu Xin wiped the cold sweat on his head.

The streamer almost rubbed his face and turned, but he was indeed not noticed.

Is this good luck or bad luck?

"It's so scary. Just before I took you, I pulled out my dagger and cut the jellyfish in half on the spot!" Lou Fei'er also whispered.

Jin Yue looked at the open door: "At least now we can conclude that with the cloak of the Invisible, even machines cannot detect us."

Xu Xin rubbed Keke's head in her arms fiercely: "If it weren't for you little guy, how could we be in such danger?"

"Ugh..." Keke seemed to be frightened by the situation just now, and let out a somewhat aggrieved yip without retorting.

"The door is also open, it's time for us to leave." Xu Xin looked at the open door and whispered to the three women, "However, you must be extremely cautious. This is inside the enemy World Tree."

He always felt that this open door... was a trap.

Generally speaking, don’t they just close the door?

Not to mention that the door of the three little mechanical jellyfish was closed when they came, but it was just opened for them when they left?

Something doesn't feel right.

It's better to be careful.

Xu Xin nodded to the three of them and walked forward.

But then he was stopped by Lou Feier.

"I am fast and have a higher chance of evading traps and the like. I will take the lead." Lou Fei'er whispered.

"I am the queen." Jin Yue also whispered.

Xu Xin nodded and did not refuse them.

fair enough.

Xu Xin and Li Wenxi both have exploratory abilities and are just in charge of command.

"Hey..."

Coco was carried into her arms by Lou Feier.

As the leader, she naturally needs the little guy Coco to guide her.

"Hey..." Coco got into her cloak, closed her big tail, and stuffed the big tail inside.

It seemed to be quite frightened by the situation just now.

In this way, Lou Fei'er walked three meters in front of the two people, while Jin Yue was behind them.

The four of them walked towards the open door.

This hall is not too big, just a room about 20 meters long and 20 meters wide, with an area of ​​about 400 square meters.

The few people walked all the way to the wooden door without any accidents and no traps found.

Lou Feier walked out of the wooden door quietly.

Outside the door is a wooden corridor that is slightly wider than the wooden door, and this wooden door that opens outward is at the end of the corridor.

She looked to both sides and examined the wooden walls covered with growth ring patterns on both sides.

There are no dangerous mechanisms or anything like that.

She turned around and was about to signal to Xu Xin and others that there was no danger outside and they could come out, when her eyes drifted past the two doors of the double door that opened outward.

At this moment, her eyes suddenly widened and her pupils shrank instantly.

She slowly raised her hand and covered her mouth to prevent herself from making a sound.

The change in her expression was noticed by Xu Xin and the other three.

Suddenly, the three of them felt their hearts tremble.

what's the situation?

What did she see?

What's behind the door?

Because the door opened outwards, the three people who had not yet walked out could not see what was behind the door, but Lou Fei'er's expression was really concerning.

Lou Fei'er rolled her eyes, and after realizing that there was no danger, she moved her hand covering her mouth, gave an OK gesture to Xu Xin and the others, and then slowly and tiptoed out.

Xu Xin and Li Wenxi looked at each other and followed.

When they reached the position in front of Lou Fei'er, they both subconsciously turned their heads and looked behind the door.

Then, the two of them made the same expression as Lou Fei'er.

Xu Xin felt an air-conditioning rush to the sky, and her whole body was covered with goosebumps for a while!

Eye.

So many eyes.

At least hundreds of eyes!

The densely opened eyes are still blinking, and the pupils are also constantly shaking and contracting.

It grows on a body as black as ink.

At first glance, countless eyes met his.

If you were in a bad state of mind, you would probably scream out loud.

Fortunately, both Xu Xin and Li Wenxi are people who have survived in this life-and-death world.

Even when hundreds of eyes met, they made no sound.

But they seemed to know why Lou Fei'er had such an expression and covered her mouth just now.

If you are not prepared to see this suddenly, it would be a bit scary...

But……

Why are there alien invaders behind the door?

Yes, the owners of these eyes are alien invaders.

Behind the two outward-opening doors, there is an alien invader in each.

Because there is a corridor outside the door and the door is at the end of the corridor, the space behind the two doors is very small.

Therefore, these two alien invaders were squeezed behind the door and were crushed by the door. Their entire bodies were less than ten centimeters thick.

Therefore, Xu Xin's first glance just now was that the entire door was filled with countless blinking eyes above the pitch black.

Behind both doors are...

Are these two alien invaders responsible for guarding this door?

...Xu Xin was once again grateful for wearing the cloak of the Invisible.

Every step here is really dangerous, but luckily they won't be discovered...

The two took steps again, walking behind Lou Fei'er.

Jin Yue finally walked out of the room and also experienced the surprise of the three people in front of her.

But she recovered quickly and left immediately behind a few people.

Several people were walking along the corridor.

Behind him, the door at the end of the corridor was not closed, but remained wide open.

The two alien invaders behind the door did not move at all. Their hundreds of eyes were blinking behind the dark door, as if they were waiting for the people in the room to come out, so that they would pounce directly.

The group of people walked very far away on tiptoe, and when they were a good distance away from the door behind them and could barely see their blinking eyes, they got together again.

"It really scared me just now..." Lou Fei'er said with lingering fear, "I was really scared and almost cried..."

She suffered the most severe mental shock.

The three people behind her, Xu Xin, all knew that there was something scary behind the door. Although they didn't know what it was before they saw it, they could at least be mentally prepared.

And Lou Fei'er suddenly met hundreds of eyes without any preparation.

Not to mention there are hundreds of eyes behind the door, it would be scary to turn around and see a stranger hiding behind the door.

Lou Fei'er didn't scream out loud, which is really a sign of strong concentration.

"Why are there physical intruders in that place..." Li Wenxi whispered in shock, "Why are they squeezed behind the door..."

"The doorkeeper," Jin Yue said concisely.

"So they will always stay there? If they insist on hiding behind the door, won't they really scare other alien invaders..."

Xu Xin was looking back at this time.

This corridor was very straight, and even after walking several hundred meters, he could still see the open door behind him.

It's just that the two alien invaders behind the door can no longer be seen clearly at this time.

"Are those two alien invaders the 'doorkeepers' of this World Tree?" Xu Xin's heart moved.

The gatekeeper is responsible for bringing individual alien invaders in and out of the World Tree.

But this World Tree does not seem to require anyone to bring it in. All you need to do is stand in the right place and stamp your feet, and the mutated vines will automatically lead you into the World Tree.

But the World Tree is certainly not accessible casually.

Therefore, the two alien invaders behind the door are probably the ones screening individuals coming in and out.

That is... "the doorman".

It's just that the doorman's state of being squeezed behind the door is really unflattering.

It's actually a bit ugly.

However, I remembered that I was controlled by Wen Guixin before, and my whole body turned into a skin that corroded the trunk of the World Tree...

Do these two doormen feel more decent?

The doorman feels a bit pitiful...

"It seems that the hierarchy in this world tree is probably very strict." Xu Xin came to a conclusion.

This is quite normal.

The leader of the alien invaders, the father of the monster, is himself the leader of the army. Strict hierarchy is normal in the army, and it will naturally be managed this way in Yggdrasil.

However, the strict superior-subordinate system of the military is not suitable for treating the masses. I am afraid that it is precisely because of this that the interior of the alien invaders has become as chaotic as it is now.

"Let's keep moving forward, Coco, lead the way." Xu Xin said to the little guy who had half of his head exposed in Lou Fei'er's arms.

"Hey!" Coco's ears twitched.

The road we just walked was just a very simple corridor.

There are no doors on either side, and no cameras can be seen.

Li Wenxi also checked it and found that there were no metal traps here.

After walking a few hundred meters, this corridor was only half way.

It is precisely because of this that Xu Xin and others stopped to discuss it first.

This corridor should be the last place of peace.

Exiting this corridor is probably the living area of ​​the alien invaders.

They were afraid that they would see more alien invaders there.

"Let's go. With this cloak of the Invisible, our situation is not dangerous." Xu Xin whispered, "However, after walking out of this corridor, don't speak easily."

While the Invisible's cloak can make them less visible, the sound can increase their presence.

In this enemy's hinterland, it's better not to seek death.

"Huh..." Coco looked at the other end of the corridor, her little head tilted.
