The dense gun muzzles were facing their position in the scarlet light, reflecting a dark red metallic luster.
The gun muzzles were like dark caves, scattered all over the scarlet crystal.
Looking at the dense gun muzzles below, Xu Xin felt himself breaking out in a cold sweat.
He was afraid that at this moment, the cannon would suddenly fire at them.
Behind him, Wang Lei and others also slid over.
But because Xu Xin and Xu Ying were blocking the way ahead, they could not move forward at all. Also, because they were positioned at the back, they could not see the situation below and could only feel the red light which was extremely dazzling at this time.
"Brother Xin, what's wrong?" Wang Lei whispered behind Xu Xin.
His feet were already on Xu Xin's body.
Then, there was a sudden force from behind, and Xu Xin and Xu Ying were almost pushed down.
"Fuck, be careful!" Wang Lei whispered to Zhao Xiaochuan who suddenly bumped into him from behind, "He almost knocked us down!"
"It was too slippery, I couldn't brake!" Zhao Xiaochuan also whispered.
"What's going on down there?" Wen Guixin also lowered her voice and asked in a low voice, "Why aren't you going down there?"
"Down there..." Xu Xin narrowed his eyes, "Yingying, go down, it's too dangerous here."
They had previously speculated that it was the light from the core of the World Tree that caused them to be discovered by the alien invaders even though they were wearing the Cloak of the Invisible.
As for why they didn't guess that it was caused by the scarlet crystal, it was because Xu Xin and the others had come into very close contact with a small piece of scarlet crystal before.
Although it was only a small piece, the distance was close, and the light they received from the small piece of scarlet crystal was much stronger than the light from the large piece of scarlet crystal that shone through the core of the World Tree and onto Xu Ying and the others.
But Xu Xin and his team had a smooth journey, but Xu Ying was discovered.
Therefore, the scarlet light should not have this effect.
And now, they are right in the core of the World Tree, and their whole bodies are illuminated and wrapped by the light of the core of the World Tree.
If the Hider's cloak fails and is detected by the numerous cannons below...
Xu Ying obviously thought of this as well. She nodded slightly, then took out a pair of sunglasses from her backpack and put them on.
They are different from alien invaders. Alien invaders have eyes all over their bodies, but they only have two eyes, which can be blocked by a pair of sunglasses.
Of course, scarlet light has strong penetrating power, so the effect of sunglasses is actually very limited, but it is still better than not wearing them.
"I'm going down."
Having said that, she slid straight out of the hole.
Then it fell from the sky and landed on the ground very lightly.
Below the cave entrance is a huge scarlet crystal, and it is only about ten meters away from the exit of the white crystal above.
The ten-meter height is very easy for the explorers, even those like Li Wenxi who have no combat ability, to jump down.
Xu Ying looked around.
The surrounding turrets are placed on the ground around the scarlet crystal.
Because it is the underground space of the World Tree, the ground is made up of the thick roots of the World Tree. On top of each thick root, there is a whole row of artillery positions.
The Scarlet Crystal is as tall as the World Tree.
She squatted down slowly, and was surprised to find that as long as they lay on this scarlet crystal, the turrets below could not attack them.
"Plop." At this time, Xu Xin also landed beside her.
He also wore a pair of sunglasses on his face.
"Brother, don't stand up." Xu Ying whispered.
Xu Xin was in a squatting position when he landed, and after hearing what Xu Ying said, he nodded slightly.
The two men first gestured to the people above to wait, and then looked around.
The underground space of this world tree is not large, about the size of a football field.
As long as they lay on the scarlet crystal, they could not see the surrounding turrets. Logically, the turrets should not be able to reach them, but those turrets were not the only crisis.
"Are these little mechanical jellyfish again..." Xu Xin whispered to himself.
"Are these small drones flying around in the air the mechanical jellyfish you mentioned before..." Xu Ying looked at the small jellyfish flying in the air around her.
Because of the strong light of the scarlet crystal, these small mechanical jellyfish were covered with a hazy red light.
It was said to be in the air, but because Xu Xin and the other person were on the top of the scarlet crystal, which was more than ten meters above the ground, the flying height of these small jellyfish was actually basically the same as theirs.
Fortunately, these small jellyfish did not approach the scarlet crystal, but were spinning around it at a constant speed and would not collide with Xu Xin and the others for the time being.
Xu Xin and Xu Ying looked at each other and nodded. Then Xu Xin made a gesture upwards, indicating that they could come down.
“Pah.”
“Pah.”
The people above also jumped down one by one and landed on top of the scarlet crystal. Everyone wore sunglasses and a layer of transparent film on their bodies.
Everyone landed very easily without stumbling or slipping.
Because the shape of the scarlet crystal is different from the World Tree Core above. The World Tree Core is a standard sphere, but the scarlet crystal is not, but a flat sphere, like a dough that has been flattened but not yet rolled.
Therefore, a large part of the scarlet crystal is flat.
This is normal. For alien invaders, they have to land here first when they come down from above. It is normal that this place is flatter.
"Finally I'm down..." Wang Lei patted his chest as soon as he got down, and said with some fear, "Oh my god, there are so many gun barrels down there, I'm really afraid they will just shoot at me..."
Everyone was squatting at this time.
Xu Xin suddenly frowned and looked at the mechanical jellyfish that were surrounding him from all directions, as if thinking about something.
Xu Ying rubbed her eyes that were stimulated by the high-intensity scarlet light and said, "You all saw what happened below just now, right?"
"It's too bright. I could only get a rough idea of it. They're all artillery batteries." Zeng Tao also said, rubbing his eyes.
"In addition to the turrets, there are three alien invaders who are mining scarlet crystals." Jin Yue said softly.
"I saw it too." Lou Feier nodded and whispered, "Everyone has a dazzling white laser in their hands."
"Besides that, there are no other alien invaders." Qin Fu looked down and said, "Maybe most of the alien invaders in this place are not allowed to enter."
"Well, they have the tools we need in their hands." Xu Ying said softly.
"Don't we have the tools?" Wang Lei asked.
"There's only the one in the boss's hand, I'm afraid it's very inefficient." Qin Fu spread his hands and said, "I observed the cutting speed of the alien invaders below, how should I say..."
"Too slow." Xu Ying pursed her lips and whispered, "The cutting speed is very slow. If it is the previous plan, we need to drill a lot of holes in the scarlet crystal and then put small nuclear weapons in them."
“But if we only use one laser cutter, our efficiency will be very low,” she said.
Everyone felt a little heavy.
Insufficient preparation.
But there is no other way. This is the best preparation they can make at the moment.
At this time, Xu Xin had already taken out the laser cutter that looked like a pen.
Because the laser gun's handle is not made according to the shape of human hands, it is not easy to hold. If you want to hold it firmly, it seems that you can only hold it forward or backward to cut like holding a dagger.
"We can try it first."
He wanted to turn on the laser cutter, but he looked at the mechanical jellyfish that were still spinning around at a constant speed with some worry.
He felt from the beginning that from their position, the artillery below could actually be hit.
What controls those turrets are not the turrets themselves, but the small mechanical jellyfish that are spinning around them.
These small jellyfish noticed the abnormal situation and sent attack instructions to the turret, and the turret attacked.
As for their current position, they can't see the artillery, and the artillery can't reach them...
The shells fired from the artillery don't necessarily have a straight trajectory like those fired by firearms, right
What if it was a mortar
Then can't we attack them who are now on top of the crystal
Xu Xin closed his eyes tightly, squeezed his eyes that were dry and uncomfortable due to the high-intensity red light, and then looked at the laser cutter in his hand.
If this laser cutter is turned on, will the strong white light be eliminated
It feels hard...
It would probably be difficult for him to do that with the invisible cloak he was wearing.
But there is one person who can do it.
"Zhao Xiaochuan, this laser cutter is for you." Xu Xin whispered and handed over the laser cutter in his hand.
"Me? Okay!" Although Zhao Xiaochuan was stunned for a moment, he still happily took the laser cutter that looked like a pen, "How do I use this thing? Do you want me to cut it here?"
"No." Xu Xin pointed at the mechanical jellyfish around him, "I guess..."
He repeated his previous guess.
Everyone nodded. Xu Xin's guess made sense.
"So, you are the least likely to be discovered among us. The task of digging the hole is left to you." Xu Xin whispered, "But this place is not suitable either. Let's find a place where it is not easy to be discovered."
The so-called opening a hole means that Zhao Xiaochuan holds the laser cutter and cuts a hole in the crystal that can be used by a person to cut inside without being noticed by outsiders.
Once such a hole is dug out, it doesn’t matter if Zhao Xiaochuan is not the one doing the cutting.
However, Xu Xin felt that even Zhao Xiaochuan should not cut in such a conspicuous position in the center of the normal square of the crystal. If he was discovered, it would be no joke.
"If we don't cut it here, then where can we cut it?" Li Wenxi whispered, "Compared to other places, this place should be very safe, right? We can't go down there, right?"
"I see." Xu Ying understood what Xu Xin meant. "Brother, you want us to directly use the broken part of the scarlet crystal to dig, right?"
Xu Xin nodded.
"Just now when I was up there, I took a general look." Xu Xin rubbed his eyes again and said in a deep voice, "Although this scarlet crystal is smooth overall, it also has some bumps and potholes."
"That's it." Qin Fu pointed to a place about five or six meters away from them, "There is a pit there."
"There are some over there, too." Zeng Tao pointed in another direction. "There are quite a few small pits on this crystal."
Xu Xin nodded slightly: "These small pits should be caused by the alien invaders who cut them here and there."
He stood up slightly and looked down: "But later, they probably felt that it was not appropriate to cut here and there, so they focused on cutting one place, which is the place where the three alien invaders are cutting now."
About one-fifth of the crystal below is already broken. This part is the consumption of the alien invaders over the past thousand years. Now the three alien invaders are constantly cutting it there.
"Oh, I understand." Wen Guixin raised her eyebrows slightly. "If we just cut at the places where they have already cut, it will not only save us some effort, but also make the appearance of the crystal look less changed and not easy to be noticed."
"That's what I mean." Xu Xin nodded. "Also, although those holes are not very deep, cutting in them can block part of the laser light."
He looked at the mechanical jellyfish in all directions: "It's best not to let these mechanical jellyfish see the laser. Dig in those holes, and if we have a few more people to surround Zhao Xiaochuan, we can minimize the exposure of the laser cutter's laser."
This should be the safest method.
"We have to surround them, which is so troublesome..." Wen Guixin closed her eyes and rested them. "Then let's start with the first step. While cutting, let's discuss how to take the cutters from the three alien invaders below."
The crowd walked lightly to the pothole nearest to them.
All around, the small mechanical jellyfish were still circling around the scarlet crystal in an orderly manner, never stopping.
Xu Xin discovered that their attention seemed to still be focused on the hole in the core of the World Tree above.
This couldn't be better.
The hole under my feet is not big, about the size of a wellhead, and only half a meter deep. The inside is full of sharp edges and corners, and you can tell at a glance that it was cut out.
Zhao Xiaochuan jumped in, then squatted down, holding the cutter like a dagger, and was about to open it, when he suddenly looked at everyone and whispered, "Cover me up!"
"I'll do it." Wang Lei's tall body blocked Zhao Xiaochuan's side and back, which was the direction most likely to leak light.
Others gathered around as well.
They also wanted to see how effective the cutter was.
“Sizzle—”
The cutter that Zhao Xiaochuan was holding in his hand suddenly emitted a flash of light.
The light was very short, only about twenty centimeters, and very bright.
But because the scarlet crystal itself was also very bright, the laser of the cutter did not flash into the eyes of Xu Xin and the others.
They've gotten used to it.
But they were also glad that they blocked the light.
After all, the sudden burst of white light in the scarlet light is still very conspicuous.
Zhao Xiaochuan held the cutter in reverse and slowly approached the crystal.
“Sizzle—”
The sound of cutting crystal is not loud.
But in this empty underground space, the sound is much more obvious.
Li Wenxi suddenly grabbed Xu Xin's arm and whispered, "Those mechanical jellyfish around here have noticed this place!"
With her ability, even the slightest movements of the small mechanical jellyfish around her cannot escape her surveillance.
She clearly noticed that although the speed of these mechanical jellyfish circling the scarlet crystal did not slow down, their attention had shifted from the entrance above to them!
"Yingying!" Xu Xin shouted in a low voice, "Your little device that eliminates sound!"
When Xu Xin called her name, Xu Ying quickly took out the small device and turned it on.
With a "boom" sound, the surrounding sounds were disturbed and could no longer be spread out.
However, Zhao Xiaochuan in the pit had already turned off the cutter because of everyone's reaction, and looked at them nervously: "How is it? Is it ready?"
Everyone looked around carefully.
Except for Li Wenxi, no one else noticed any difference between these small jellyfish and the previous ones.
"It's alright?" Zhao Xiaochuan breathed a sigh of relief. "Then I'll continue cutting. This laser cutter seems to be very easy to use. The speed should not be slow. I..."
"Wait a minute..." Li Wenxi whispered, "Don't do anything yet."
