In the red fog, the explorers' plan slowly unfolded.
After the three alien invaders were controlled, Xu Xin handed the three cutters in his hand to them, and under Wen Guixin's control, they began to cut at four different locations on the scarlet crystal.
"Hey, they're cutting so slowly!" Because of the red mist, Zeng Tao had to get close to one of the alien invaders to see its movements clearly. She stared at it for a few seconds, then turned to Wen Guixin and said, "They're cutting another tiny bit of scarlet crystal!"
"Ah? Let me see."
Wen Guixin had just directed the last alien invader to a certain location, and then walked in to observe: "It's true. You guys, cut faster, use the fastest speed, and cut the largest pieces you can!"
The bodies of the three alien invaders obviously paused for a moment, then the cutting action stopped, and then the eyes all over their bodies began to blink continuously.
The alien invaders cannot understand human language, but Wen Guixin did not use language to command them. The words just now were just said casually.
But it seemed that he was somewhat resisting Wen Guixin's orders.
"Hmm?" Wen Guixin frowned, "Hurry up!"
The alien invaders' bodies trembled, their eyes blinked wildly twice, and then they immediately began to cut according to the method Wen Guixin had just said.
The cutter's laser pierced into the scarlet crystal and made a wide circle around it.
"Not bad." Wen Guixin nodded with satisfaction.
"Wow, it seems that these alien invaders are very resistant to cutting into large pieces." Qin Fu observed, "Then our previous guess about why they cut into small pieces of crystal may not be wrong."
"Anyway, in this case, there should be no problem." Wen Guixin looked around and took a few steps into the depths of the red fog. "Those artillery positions are gone. This place has become much safer. Where are Xu Xin and the others?"
"Here." Xu Xin's voice came from the depths of the red fog.
Xu Xin had actually been observing one of the alien invaders and had never left, but now the red fog was too thick and no one could see other people more than one meter away.
After seeing that the alien invaders' cutting speed was not slow, he was temporarily relieved.
"Then what should we do?" Lou Feier pointed at herself and the others, "It seems... there is nothing for us to do?"
"Our mission is to be vigilant at all times," said Xu Xin.
In this thick red fog, he actually felt very insecure because his field of vision was too narrow.
It is so narrow that he may not be able to see the enemy even if he is in front of him.
"Don't worry, if there are any metal objects, I can find them immediately." Li Wenxi raised his head and said with a smile, "So, isn't it a wise decision to bring me along for this mission?"
"Indeed." Xu Xin also smiled.
In this environment of red fog and scarlet crystals erupting, if the alien invaders are not sick, they should not enter the underground space in this state.
Just look at the state of the three alien invaders who fell to the ground even after being covered with protective film.
Therefore, before the red fog dissipates, there is a high probability that no more alien invaders will come in.
But the machine may come in to check again.
Therefore, before the red fog dissipates, Li Wenxi's ability is crucial.
"Then it's up to you." Xu Xin squeezed Li Wenxi's hand, then looked around, "I... will go check around a bit."
It was all red fog and I couldn't see anything.
But he still wanted to check out the surrounding walls.
Who knows what we might discover
It's not a good idea to wait here all the time.
"Ah? Goodbye." Li Wenxi grabbed him and said, "We'd better not separate. If something happens, how can I remind you if you are too scattered? I can't yell for you to pay attention."
Xu Xin pursed his lips.
That's true.
"So... just wait like this?"
If each of them had a cutter, they could speed up the progress, but now there are only four cutters, and several people can only wait here.
"Then just wait." Lou Feier walked to Xu Xin's side, "It's too tiring to be so tense all the time. It's time to take a break. Otherwise, it would be bad if a crisis comes and you can't hold on."
Zeng Tao also came over and said, "Yeah, it's no use for you to look around. What are you looking for? Are you looking for those loose walls of the world tree roots that might have something behind them? I can't even pry them apart, so what's the point of you finding them?"
That's true.
Xu Xin looked into the depths of the red fog.
… Let’s just forget about it for now.
Xu Xin looked at her and said, "Come to think of it, do you still think that inhaling this scarlet mist is addictive?"
“Not now.” Lou Feier shook her head, “But just now, when the scarlet crystal suddenly burst into light and affected us, I had a hint of that feeling again in those few seconds.”
"Neither do I." Zeng Tao took a deep breath, "Ahem..."
Then he was choked by the red mist.
"Hmm... cough cough! And, cough, is this red mist really the same red mist as before? It doesn't smell good at all!"
Doesn’t smell good
ah…
Xu Xin remembered.
This thick red fog is somewhat different from the red fogs they had encountered before.
If it was the same red fog as before, when it was so thick, Xu Xin and others would have smelled it as extremely foul and suffocating!
The first time he encountered the red fog was in an underground iron room.
At that time, in order to avoid the red fog, he climbed up the ladder to the ground with all his might, and he was exhausted.
The smell, like that of canned herring that had gone bad, was something he would never forget.
But for people like Lou Feier and Zeng Tao who have undergone blood vein mutation, this red mist is very sweet.
But the red mist here has no smell at all.
That's a bit strange.
"It's possible that this red mist has been purified and optimized?" Qin Fu walked over from the depths of the thick red mist and guessed, "This is the red mist that will submerge the scarlet crystal and make it release energy."
The red mist that makes the scarlet crystal shine...
I always feel like it could be used.
"What a pity, there is no device that can collect gas." Xu Xin sighed.
With their current level of technology, it is very simple to make a device to collect gas.
But who would have thought of doing it
"Collect gas? Do you want to collect this red fog?" Wen Guixin also walked out of the thick red fog and asked.
"Yes. I feel that this gas, combined with the large pieces of scarlet crystal that have been cut, can make the scarlet crystal release a stronger light, which can play a big role."
He glanced at the alien invader beside him that was completely controlled by Wen Guixin: "With this cooperation, we won't be afraid even if we encounter many alien invaders."
"In fact, I feel that a large piece of concentrated scarlet crystal alone is enough." At this time, Xu Ying suddenly teleported to their side and said, "The light of this concentrated crystal alone is enough to make ordinary alien invaders drink a pot. Besides, didn't you say that the light of a small piece of scarlet crystal can drive alien invaders crazy?"
That's not wrong.
But the scarlet crystals in the red mist can drive alien invaders with protective touch crazy.
Forget it. Judging from the current situation, I’m afraid not many alien invaders have protective membranes.
"Let's take a short break. When Zhao Xiaochuan gets tired, we'll go and switch with him."
Xu Xin and his group became more alert and sat in the red fog, waiting to be cut.
Time passed by minute by minute, and the red mist showed no sign of dissipating.
Similarly, there are no alien invaders or even machines entering this underground space.
Everything seemed smooth and peaceful.
During this time, Xu Ying used her teleportation ability to go out and take a look, and she came back in just three minutes.
She told everyone that the outside of the World Tree was still very peaceful and not much had changed since they arrived.
But the control area above, which is the central control area of the trunk where the core of the World Tree is located, is now on absolute alert. A large number of weapons are gathered there. She was really shocked when she went up.
As for the scarlet crystal, Zhao Xiaochuan was still working very hard to cut it, and he had become addicted to it.
Even when Xu Xin and others wanted to find someone else to cut the deal with so that he could take a break, he simply refused.
"I'll do it, just watch me!" His voice came from inside the scarlet crystal.
The red mist had already followed the channel he had cut out and diffused into the interior of the scarlet crystal, causing it to release a very intense light.
This made Xu Xin and others a little worried about Zhao Xiaochuan, who was inside the scarlet crystal and wrapped in the scarlet crystal.
However, every time he was asked, his voice was full of energy.
It seems that the four layers of protective film are still very effective.
Xu Xin could only remind him that if he felt any discomfort he should come out immediately because the protective film was disposable and might lose its effectiveness.
"Don't worry, Brother Xin, I value my life very much!" Zhao Xiaochuan replied.
The three alien invaders controlled by Wen Guixin also performed their duties conscientiously.
The positions of the three of them formed an equilateral triangle, digging inwards from three directions outside the scarlet crystal.
Moreover, probably because they were designed to do this, they dug faster than Zhao Xiaochuan. However, they had no intention of hiding the entrance of the hole, and each hole led straight inward.
Fortunately, Wen Guixin gave good orders, asking them to dig a smaller hole outside and then expand the hole inside, so that the hole made by the three people was not very conspicuous.
Xu Xin and others have been keeping their nerves high, alert to the risks that may come at any time.
About two or three hours later.
"Come up and take a look. Zhao Xiaochuan's side is almost ready."
Jin Yue's voice came from above the scarlet crystal.
"Let me go up and take a look." Xu Ying stood up.
"Take me with you." Xu Xin said.
The two of them were teleported directly to the scarlet crystal and to the side of the pit that Zhao Xiaochuan had dug.
In order to make the pit less conspicuous, Zhao Xiaochuan dug half a meter downwards, then dug another one or two meters to the side, and continued to dig diagonally downwards.
So, if you look from above the pit, you can't tell how deep the pit is.
But in fact, the pit was already very deep at this time.
The scarlet crystal is twenty meters high in total. Zhao Xiaochuan dug nearly ten meters inside at an angle of at least forty-five degrees, and has already reached the deepest part of the scarlet crystal.
"How is my masterpiece!" Zhao Xiaochuan's forehead was covered with sweat, his clothes were soaked, there was some fatigue between his brows, but more of excitement.
"Okay, come up quickly, it's so hot!" Wang Lei reached out to Zhao Xiaochuan and pulled him out.
This passage is not wide, with the widest part being only about 60 to 70 centimeters in diameter, which is enough for only one person to crawl in.
Xu Xin and Xu Ying slid down to take a look.
Because every time a piece of scarlet crystal was cut, a large amount of heat would be released, causing the interior of the half-meter-thick passage he dug to be extremely stuffy. The temperature was definitely over 40 degrees, and it felt like almost 50 degrees.
"They actually dug right into the innermost part of the scarlet crystal." Xu Xin was very surprised. After coming up, he said to Zhao Xiaochuan, "You did a great job."
"Ha ha!"
Zhao Xiaochuan wiped the sweat off his head and said complacently: "The diameter of our small nuclear missile is only about 50 centimeters, it can be completely stuffed in. Moreover, I plan to extend and cut from this channel in all directions, cut out a few more positions, and directly make a super explosion inside the scarlet crystal!"
"That's a good idea, but I think you should take a break." Xu Xin reached out and grabbed Zhao Xiaochuan's arm as he was about to jump in again, "You're obviously very tired now."
“Uh…” Zhao Xiaochuan’s body shook immediately when Xu Xin grabbed him.
He had been working in a high temperature environment for a long time, and everything he saw was emitting an extremely strong scarlet light, causing him to feel very dizzy.
"Let me do it." Jin Yue took the cutter. "I've been watching him cut for a long time, so I'm familiar with it."
"Ah? Then let me do it!" Wang Lei said hurriedly, "I have also been observing for a long time. How can I, a grown man, let..."
"Forget it. You are such a big guy. Can you move around in this small hole?" Xu Ying waved her hand. "Let Jin Yue do it."
“Uh…it seems so…” Wang Lei touched his head.
"Okay then... let's start digging from this position..." Zhao Xiaochuan immediately explained his plan to Jin Yue.
Xu Xin and Xu Ying went to check the results of the other three alien invaders.
They are all very good. Although not as deep as Zhao Xiaochuan, almost every one of them has already cut a second channel that can accommodate small nuclear weapons.
The progress is very smooth.
The two returned to the crowd and explained the situation.
"Then let's just keep waiting." Qin Fu spread his hands, "I didn't expect this place to be so safe."
At this time, Xu Ying suddenly pointed upwards and said, "Hey, are you guys interested in going up and taking a look?"
…
"ah?"
"Go up?"
"Are you serious?" Xu Xin couldn't help but twitch his lips.
"Since we are just sitting here doing nothing anyway, why don't we go inside their World Tree and take a look? Maybe we can find a few more cutters."
Xu Ying pointed at the alien invader beside her and said, "Although the cutting speed is not slow, it will take at least five or six hours to achieve our goal. Are we going to sit idle during this time?"
"This..." Li Wenxi hesitated, "Isn't it too dangerous? Besides, we don't have the ability to go up now, right?"
"Of course." Xu Ying pointed at the alien invader, "It is definitely capable of taking us up."
Everyone looked at the alien invaders.
Yes.
As a worker who cuts scarlet crystals, this alien invader is definitely one of the core members of this world tree. It is almost certain that it is a resident of this world tree.
Therefore, if you control it, you can definitely get to the top.
"... You mean, let one of us take its place, and then I control it and take you up?" Wen Guixin immediately refused, "No, you know how dangerous and complicated our situation is now. You are just kidding!"
"No." Xu Xin also refused.
Going up at this time would be tantamount to seeking death.
Isn't this just giving the other party a head
"I think we have some considerations for going up there." Xu Ying pointed at the thick red fog. "If we stay here for a long time, I feel like something might go wrong. Why don't we rotate them a bit? Those who don't need to cut can go somewhere else."
"Besides..." Xu Ying looked up and saw a red mist spreading. She said with interest, "The outside may have been messed up by that monster. We may be able to take away something in the chaos."
"I'd rather not."
Everyone shook their heads.
"snort… "
Xu Ying bit her lip, then gritted her teeth.
"Then I'll go up by myself. Anyway, there are many alien invaders in the inner space of the tree trunk. They will definitely go up. I can just find a chance to blend in with them."
"Yingying, you..."
Xu Xin felt helpless.
They are over 300 years old, how could they be so willful at the critical moment
And if she went up, they would lose a guarantee and a retreat that could be teleported at any time.
"Yingying..."
"Don't persuade me, sister-in-law." Xu Ying waved her hand, "Brother, come with me, I have something to tell you."
Xu Xin looked at Xu Ying, his eyes trembling slightly.
He seemed to understand why Xu Ying was so willful.
This... maybe this is her last act of willfulness.
Xu Xin's heart ached.
Could it be that Yingying still feels that she is going to die
Their plan clearly did not involve the weapons she gave them.
What does she want to say to herself
Xu Xin stood up and followed Xu Ying into the depths of the red fog.
"Yingying, you..."
"Brother, it seems that the weapon from another time and space that I gave you must be used."
