Chapter 688 Escape Quietly

"Hey!" Coco raised her little head, looking very proud.

Lou Fei'er's curiosity was suddenly aroused: "What did you get just now?"

Xu Xin looked towards the front of the corridor: "Let's go ahead and talk as we walk."

When Xu Xin Jinyue entered the bracelet, Li Wenxi had been chatting with the monster for some time.

In their hands, they were holding the two items that Xu Xin had put into the bracelet from the counter.

A stack of transparent film, and a metal rod that emits laser light.

The monster was obviously very surprised by the two things in its hands, making its already ugly face even uglier and looking extremely ferocious.

"The transparent film is used to be worn on the body to resist the corrosive effect of the concentrated scarlet crystal light on alien invaders... something like a raincoat."

"And the metal rod that can emit short laser light with a temperature of hundreds of millions of degrees is a tool used to cut scarlet crystal."

Several people were walking deeper in the corridor, and Xu Xin explained to Lou Fei'er in a low voice.

"...Huh?" Lou Fei'er's eyes widened, "...What a coincidence? Why is there such a thing here?"

"This is just a coincidence. According to the monster, this World Tree should not usually have so many alien invaders gathering. This time there are so many alien invaders gathering, probably because of these two Something." Xu Xin said.

"Yes." Li Wenxi took over the words and said, "These alien invaders are probably holding a selection here."

"Selection?" Lou Fei'er was a little confused, "Selection...what?"

"Select a worker who processes scarlet crystal." Jin Yue whispered.

"This..." Lou Fei'er didn't know what to say.

How many of them happened to fall into a selection process by mistake?

"The monster said that the reason for this selection may be that the alien invader's giant ship was dispatched again after a thousand years."

Xu Xin looked deep into the corridor and said while observing: "The activation of giant ships requires a large amount of concentrated scarlet crystal as fuel. This time the four giant ships are activated at the same time, perhaps to distribute them to other alien invasions on the earth. Most of the 'source of life' has been consumed, so more workers are needed to cut the scarlet crystal."

The monster said that cutting the scarlet crystal is a very confidential and arduous task. This work must be completely controlled by the leader. Only in this way can it truly achieve complete control.

Even a little bit of smuggling and leakage will not work.

Therefore, in order to minimize the possibility of leakage, the workers for this work are all carefully selected by the leader, and the number is also kept to a minimum.

The fewer workers there are, the less likely things are to go wrong.

If there are few workers, the productivity will not be high.

Therefore, the "production capacity" of the scarlet crystal as the source of life is only barely sufficient every time it is distributed to all alien invaders.

Not even enough, so every time there are less obedient alien invaders unable to obtain the "Source of Life".

But this time, after a lapse of thousands of years, the giant ship was activated again, consuming a large amount of concentrated scarlet crystal that had been cut and prepared to be distributed to the alien invaders as the source of life.

At this time, if we do not increase the number of staff, I am afraid that most of the alien invaders will not get anything when the "Source of Life" is distributed next time.

That is absolutely not possible.

We are already in this situation now. If there is another situation where the "Source of Life" cannot be released, it will be chaos!

Therefore, the monster believes that there are so many alien invaders gathered in this world tree, and this tool for cutting scarlet crystals appears, it is obviously to select new workers to cut scarlet crystals.

As for why these two things are displayed like exhibits, I'm afraid it's just to let these alien invaders come into contact with them.

Anyway, in the World Tree, everyone has no weapons. The mechanical jellyfish are flying everywhere to monitor all locations. It is impossible for these two things to be snatched away.

But the other party did not expect that Xu Xin and others used small pieces of scarlet crystal to disrupt the scene, and then stole these two items with the cloak of the Invisible.

"It's actually like this..." Lou Fei'er was still a little puzzled, "So, the scarlet crystal was really cut by the alien invaders themselves? I thought their technology was very advanced and everything had been cut. Even if it can be automated, it will still require 'workers' to cut it manually."

She curled her lips and said.

"I asked about this too." Li Wenxi smiled and said, "As far as the monster knows, this is because the light of the scarlet crystal is too powerful, and the machine cannot be exposed to this light for a long time, otherwise it will be directly damaged due to overheating. Moreover, Rather than letting machines that may be hacked to mine, it would be more secure if they could do it themselves, and the cost and difficulty are much lower.”

Just now, Xu Xin took out a whole layer of transparent film from the platform. When he entered the bracelet, he made a rough estimate and found that there were at least thirty or forty sheets of this kind of film on that layer.

The monster also told them why there were so many, because this film is disposable.

Every time you cut, you need to consume and lose one piece of this film.

This is how they resist the intense light of concentrated scarlet crystals.

They do not have materials that can completely withstand the radiant light of concentrated scarlet crystal without being damaged. If a machine is used for cutting, it will be necessary to replace the shell of the machine from time to time, which is very troublesome, and the machine is also prone to malfunction.

As for the alien invaders to mine as workers, they only need to put on this transparent film and hold this laser cutter to mine scarlet crystals.

The cost of consuming a film each time is very low and hassle-free, because the alien invaders have a strong recovery ability. As long as you feel uncomfortable, just leave as soon as possible, and they will recover on their own after a while, unlike machines. Still needs fixing.

This is the reason why the alien invader leader always uses hand cutting.

"So that's it." Lou Fei'er understood now, "Then we have a disposable film and a cutting gun for self-defense, can we destroy the scarlet crystal? How to destroy it? Use the cutting gun to tear the scarlet crystal into pieces Is it a block..."

"Of course not." Xu Xin said.

The method given by the monster was to dig out some small holes in various locations of the scarlet crystal, then stuff small nuclear weapons into them, and then detonate them directly after Xu Xin and the others moved away.

The core temperature of a nuclear weapon can reach hundreds of millions, and a temperature of hundreds of millions is enough to evaporate concentrated scarlet crystals.

"Ah..." Lou Fei'er was a little confused, "Wouldn't it be better to just use a large nuclear weapon to detonate it?"

"In that case, the destruction may not be complete." Li Wenxi said, "No matter how large the number is, as long as there is an explosion outside the scarlet crystal, even if the core temperature can reach hundreds of millions, I am afraid that it will only evaporate part of the outer layer of the scarlet crystal. , it is impossible to destroy them all.

If you want to destroy them all, it is best to bury nuclear weapons in various locations of the scarlet crystal, blast them at multiple points, completely blow up the scarlet crystal, and then use another big one. "

This is the method that the monster recommends to Xu Xin and the others that is most likely to succeed based on their existing equipment and weapons.

Xu Xin touched the other bracelet on her wrist.

That was a super weapon from another time and space that Xu Ying gave him. If possible, Xu Xin doesn't want to use these weapons.

Fortunately, this plan did not use the weapons here. If this plan succeeds, there will be no need to use the weapons here.

Lou Feier was about to say something when suddenly, Jin Yue behind her said: "Be careful, the entrance to the corridor is open again."

Everyone looked back.

The door that was already far away from them opened a gap again, and another small mechanical jellyfish flew in through the gap.

At the same time, scarlet light suddenly shone from the other end of the corridor, illuminating the entire dim corridor in scarlet!

"It's coming, stay away."

There was only one small jellyfish that was easy to hide, so Xu Xin and the others did not have to lie down, but leaned against the wall.

The little jellyfish clutching the scarlet crystal flew through the corridor at high speed. It only took a few seconds to leap over a section of the road that Xu Xin and the others had walked for so long, and passed by them in a flash.

The moment the mechanical jellyfish flew by, Xu Xin and others felt a slight dizziness in their heads.

The light of the small piece of scarlet crystal seemed to have become more dazzling and powerful after being robbed by the alien invaders. It shone on Xu Xin and others, which really made people feel uncomfortable.

Fortunately, it only lasted a moment, and the little mechanical jellyfish was gone.

"gone."

Several people left the wall.

"Half of the scarlet crystals have been recycled." Jin Yue said.

"...We move quickly."

When the scarlet crystal is completely recovered, the situation may become more serious for them.

These two tools that can cut scarlet crystal were stolen by them!

Xu Xin didn't believe that the administrator of this world tree didn't notice this. The sky is full of small mechanical jellyfish, and every mechanical jellyfish is probably a camera. How could it not be discovered?

"By the way, isn't this a big step for us?" Lou Fei'er looked at the little mechanical jellyfish going away and whispered, "As long as Yingying and Wen Guixin can discover the location of the scarlet crystal, Isn't it going quite smoothly? Why did you look so worried when you came out just now?"

"It's not that simple..." Xu Xin shook her head helplessly.

"The current situation is actually not optimistic." Li Wenxi said with some distress, "We have stolen those two things. I am afraid that the other party is already doubting whether our goal is the huge scarlet crystal."

This selection of "Scarlet Crystal Cutter" must have been announced to most of the alien invaders, otherwise there would not have been so many alien invaders coming to this World Tree.

In other words, in the eyes of the managers of this world tree, this deliberate chaos was probably organized by rebels in order to seize the scarlet crystal cutter.

Although Xu Xin and the others are not suspected, the other party will definitely increase their supervision of the scarlet crystal.

After all, the cutters were stolen.

In their view, the rebels who stole the cutter would definitely cut the scarlet crystal to obtain the source of life.

The most important thing is that if they find out that the important "gatekeeper" of the World Tree is no longer there, they will definitely be more vigilant.

The situation has really escalated. Although their action has obtained essential tools, it has also greatly increased the vigilance of the alien invaders.

"...It's useless to talk about this now. We can only take one step at a time." Xu Xin glanced at the cloak of the invisible person on his body. "With this cloak, even if the other party increases supervision, we still have the possibility of success. ,and……"

Xu Xin turned the bracelet: "The monster just said that when we really want to destroy the scarlet crystal, we will release it, and it will attract some of our attention."

Monsters might actually get most of the attention.

If a monster appears, the other party is likely to think that this series of events is caused by the monster, and will go all out to hunt it down.

Just let Xu Xin and the others complete their mission.

"Is it a monster..." Li Wenxi whispered to herself, then became worried, "Can it... really be trusted?"

"It makes no sense to say this now. The plan itself is also its proposal." Xu Xin shook his head gently, "If we don't trust it, there is no need for us to come here."

"That's right..." Li Wenxi pursed her lips, "Furthermore, Sister Guixin has communicated with it a lot, and now she trusts it. I...I believe in Sister Guixin's judgment. It's just feeling, putting our final I always feel uneasy when my fate is placed in its hands."

"It doesn't count as being handed over to it." Xu Xin said, "It is only responsible for attracting firepower. The final result still depends on our efforts."

"Um."

At this time, Xu Xin and others had reached the end of the corridor.

At the end of the corridor, there is another door.

However, the door is not closed, but wide open.

Behind the door is a very bright wooden hall, which is almost the same as the one when they entered.

"...I'll go first." Lou Feier took a few steps forward.

The wide open door feels like inviting you into a urn, but there is only one way they can go.

After walking out of the door, Lou Fei'er turned back slightly and looked behind the door.

Then her pupils shrank again, held her breath, and winked at Xu Xin and the others.

...really?

Is there a "doorman" behind the door here?

Xu Xin and the other three walked out of the door calmly, then glanced behind the door.

It was as dark as ink, squirming, and hundreds of eyes were blinking constantly.

Well, that's true.

At this time, Li Wenxi beside her gently pulled Xu Xin's arm with her hand, and then pointed upward.

Xu Xin looked up.

The entire ceiling was covered with small, dark holes as thick as a finger.

The small openings are densely packed, almost right next to each other.

Looking carefully into these small holes, there is a smaller silver tip in each small hole. These silver tips seemed to be alive, swinging slowly in every small hole.

All the small holes were like this, and the swing of the silver tips made the entire ceiling seem to be crawling.

The entire ceiling was like a dense wormhole, with bugs squirming in it. This caused even Xu Xin, who didn't have any trypophobia, to feel a little numb at the moment.

Li Wenxi made a gun gesture with her hand.

Xu Xin and the others understood immediately.

These dark little holes are all... gun muzzles?

Are those little silver needles...bullets?

So, is it possible to swing slightly to adjust the direction of attack?

...In short, this room is very dangerous, with gunshots all over your head.

At the same time, this room is not just about this door.

In addition to the door they just entered, there were five more doors in front of them.

There are two doors on the left wall, one on the opposite wall, and two more on the right wall.

These doors should all lead to the buildings in the wall.

Xu Xin rubbed Coco's head in her arms.

"嘤...嘤."

After having his head rubbed, Coco, who had been shrinking, stuck out his little head again.

The little guy saw the black holes on the ceiling, and quickly retracted his little head halfway, only exposing his two eyes, and then extended his little paws half way, pointing to the door directly in front of him.

Is it really that door?

Li Wenxi and the three of them all saw Keke's little move. Lou Fei'er took the first step and walked towards the door.

Xu Xin and Li Wenxi followed closely, while Jin Yue glanced at the long corridor behind and followed.

Lou Feier walked to the door.

This door also opens to the left and right, but it is tightly closed.

"Hey..." Coco stretched out her two little paws and made a push forward motion.

Can I just push it away?

Xu Xin took a few steps forward and nodded to Lou Fei'er.

The two of them no longer hesitated and pressed on the door, one on the left and the other on the right.

The double doors were gently pushed open.

It's very silky and doesn't require much effort.

After just pushing open the gap enough for one person to pass, the two stopped moving.

Don't open it too high, as the risk of being discovered will increase.

Behind the door is a large ball made of vines.

Vine ball elevator?

Several people looked at each other, nodded slightly, and then walked directly inside.

Xu Xin reached out and pushed the door open.

With a slight sound, the wooden door closed.

Then, before a few people could react, the vines under their feet began to squirm!

Several people were a little unsteady for a moment and quickly helped each other.

But from the gap between the vine balls under his feet, four vines as thick as arms were covered with blood tattoos on their bodies!

The four of them knew what was going to happen next and did not speak or resist.

These four vines slowly wrapped around the bodies of the four people.

As the four vines gradually became entangled, the vines woven into the ground under the four people's feet began to gradually become sparse.

Finally, when they were completely entangled, their feet were already hanging in the air.

Gusts of cold wind blew up from below.

Xu Xin looked down and could already see the ground a hundred meters below.

Then……

The vines tied to several people suddenly softened, and they suddenly began to fall freely as if they were bungee jumping with ropes tied to them!

"Well……!"

Fortunately, all four of them restrained themselves from shouting.

Finally, when they were about ten meters above the ground, the vines wrapped around them exerted force again, slowing down their descent, and then...

They landed smoothly on the ground.

Then, after the blood-striped vines hanging from the crown of the World Tree slowly released from their bodies, they shrank back towards the World Tree at an extremely fast speed. It only took two seconds for them to retract and disappear.

"We... just came out like this?" Li Wenxi covered her pounding heart and said in disbelief.

"You are finally out."

At this time, Xu Ying's voice came from behind several people.

Xu Xin looked back and saw Xu Ying standing behind them with a relieved expression. The purple-black vortex under her feet was gradually disappearing.

She must have just discovered the situation here somewhere else and teleported here directly.

"Brother, you guys are so slow. If you are any slower, I will go straight in to find you." Xu Ying punched Xu Xin.

Xu Xin grabbed her fist and said hesitantly: "You... found the place?"

"Of course. What about you?"

"We have gained a lot." Li Wenxi laughed softly.

"Well, this is not the place to talk. Let's get out of here first."

"Okay, I've brought the others to safety, let's go find them now."
