"Is it really okay for you to teleport so far at once?" Xu Xin asked Xu Ying with some concern.
"A few hundred kilometers is still far?" Xu Ying waved her hand nonchalantly. "Don't worry, as long as it's a place I've been to, there will be no problem. Even if I send you back to the World Tree now, it will be no problem."
At this time, everyone was in a world of extreme darkness. Only the core of the tree house was emitting bright white light, illuminating the area of dozens of meters around it.
There are some wet rock walls everywhere.
They are now in a cave in the underworld.
That’s right, Xu Ying directly teleported everyone to a cave in the underground world that they had passed by before.
"Don't force yourself." Xu Xin reminded.
"Oh, you're so annoying." Xu Ying turned her head away.
"Okay, okay, let's get down to business!" Wen Guixin, who was sitting on the ground leaning against the stone wall, asked, "What on earth did you go through? Why did it take so long to get in there?"
"Yes, we waited for you for at least half an hour after we came out." Zeng Tao was sitting next to Lou Fei'er at this time and punched her lightly, "What on earth did you go through?"
"The focus is on your side, right?" Lou Feier asked the people who entered the other side of the World Tree, "How is your side? Have you found a way to get closer to the Scarlet Crystal?"
"Of course, we have overcome many difficulties and even killed several alien invaders!" Zhao Xiaochuan said with some pride.
"You also killed several alien invaders?!" Li Wenxi's eyes widened in shock, "Is this true?"
"How could it be false? I also have a contribution in this matter!" Wang Lei pounded his chest with a proud look on his face.
Qin Fu leaned against the stone wall nearby, spread his hands and said, "I say, you don't think that killing a few alien invaders is a good thing, do you?"
Xu Ying also said helplessly: "The situation here is not optimistic."
…
After they discovered the core of the World Tree that was glowing scarlet light, they began to look around for a way to enter the underground space of the World Tree and get close to the scarlet crystal.
But just as they were looking for the entrance, uninvited guests arrived.
No, actually they are the uninvited guests. It should be said that the residents of the World Tree have arrived.
It should be the "gatekeeper" who brought people in, which made the alien invaders living in the World Tree notice something was wrong.
"So, you just gave these two alien invaders to...?" Li Wenxi asked in surprise, "How did you do that?"
"The method we use is actually very simple and crude."
These two alien invaders descended from the sky using the vine ball elevator that Xu Ying and her friends were very familiar with.
Probably because the strong ones had already left with the army, the only ones left in the World Tree were some alien invaders with very weak combat capabilities, so the two alien invaders who came to inspect were very weak and didn't even bring any weapons.
The feeling it gives people is... just come down to take a look.
But this is also normal. Carrying weapons should not be allowed in the most important world tree. This can be seen from the fact that all military members who carry weapons live in the area outside the world tree.
The interior of this most important world tree has been very safe for nearly a thousand years, so they probably don't feel there is any danger at all.
They came down to check, probably because they just felt it was a bit strange and wanted to see what was going on below.
So, at first Xu Ying and the others did not want to alert the enemy, but just waited quietly for the two alien invaders to check.
Zhao Xiaochuan even ran to the vine ball elevator to check the condition of the elevator.
But what surprised Wen Guixin, Xu Ying and others was that these two alien invaders gradually noticed the existence of their group during the inspection!
One of the alien invaders moved in front of the crowd and kept looking at them.
A few seconds later, it made an unpleasant and shrill mechanical scream and rushed towards the vine ball elevator.
For alien invaders who have never seen humans, seeing humans is like seeing super scary monsters!
Especially for this alien invader, it was like looking closely at a few peculiarly shaped stones from a close distance and suddenly discovering that these stones were not stones, but a few ugly monsters disguised as stones!
Therefore, even though it was clearly wriggling on the ground, it gave Xu Ying and the others a feeling of... rolling and crawling.
Run away with strange screams!
This also caused another alien invader to look this way.
It didn't seem to notice Xu Ying and the others, and was puzzled by its companions' screams of fear.
Xu Ying and others also reacted on the spot.
They were discovered!
They certainly couldn't let the alien invaders return to the vine ball elevator, otherwise their presence here would be completely known!
So they immediately started to act.
Xu Ying teleported directly and blocked the path of the screaming alien invader, causing the alien invader, who had noticed their presence, to let out another extremely shrill and unpleasant scream and flee in another direction.
At this time Zeng Tao had already arrived. She raised her foot and kicked the alien invader head-on.
The huge power contained in the small body directly kicked out the alien invader's eyes that were wide open with fear, and at the same time kicked the alien invader to the ground.
Then, Wang Lei arrived. He jumped up and smashed directly on the alien invader. He pressed his hands on its body and the terrifying force pinned it to the ground.
Their huge movement caused their originally low-visibility figures to be directly exposed to the eyes of another alien invader that was moving towards them.
The alien invader immediately let out a strange cry and rushed in the opposite direction.
But Wen Guixin and Qin Fu had been waiting for it for a long time.
Neither of them used guns, but instead picked up the weapons they had previously used.
Wen Guixin swung her scythe directly, and with a flash of cold light, she cut off a part of the alien invader's body. At the same time, she hooked the inside of the sickle to stop the alien invader's forward momentum.
Qin Fu shot arrows repeatedly from the bow in his hand, directly nailing the part of the alien invader's body close to the ground, making it temporarily unable to break free.
The alien invader, screaming in pain, was suddenly restrained in place.
At the same time, Zeng Tao caught up again, shouted, jumped up suddenly, and then smashed the alien invader hard!
Her terrifying weight directly crushed the alien invader!
Because the alien invaders were covered with eyes, the scene was a bit uncomfortable at one point.
At this point, Wang Lei and Zeng Tao each took one of the two alien invaders and pinned them to the ground with brute force, making it impossible for them to break free.
It was easy after that. Wen Guixin took one in each hand and directly destroyed the two alien invaders.
Moreover, the erosion speed of these two alien invaders was very fast. Compared with the ten minutes it took to erode the gatekeeper, these two alien invaders were completely eroded in less than a minute.
It is enough to show that the physical strength of these two is far lower than that of the "gatekeepers" of the World Tree.
"Come to think of it, the two alien invaders we encountered weren't strong at all." Zeng Tao waved his fist lightly, "It felt like they could be easily knocked away."
"Maybe he's a fat otaku among the alien invaders, a scum with extremely low combat power." Zhao Xiaochuan shrugged, then frowned, "Alas, my ability has actually failed, making me feel really insecure now..."
"… Yeah, why were we discovered?" Lou Feier asked in confusion, "The alien invaders didn't find us at all, otherwise we wouldn't have made it out alive."
"We speculate that it was caused by the light of the World Tree's core or the scarlet crystal." Xu Ying said, "The light of the World Tree's core shining on us may have increased our sense of presence a little, causing the alien invader to discover us when observing us closely."
"Ah..." Li Wenxi pursed her lips, "So, the Cloak of the Hider is not that useful there..."
…
After controlling the two alien invaders, Wen Guixin tried to manipulate the two alien invaders to control the vine ball elevator to enter the underground space and approach the scarlet crystal.
But without success.
Because the vine ball elevator could not enter the underground space, it could only rise into the interior of the World Tree.
But if that's the case, wouldn't it be further away from the goal
So they had no choice but to search nearby again, trying to find the entrance to the underground space from here.
As a result, they found the entrance by accident.
They were surprised to find that the entrance to the underground world was right in front of them at the core of the huge world tree that emitted a mixture of white and scarlet light!
"Brother Xin, you didn't see that there was a very secret hole in the core of that World Tree!" Zhao Xiaochuan gestured with his hands and described, "The location of the hole is actually right above the big core!"
The core of the World Tree is very large. Even if only half of it is exposed above the ground, the highest point is still thirty or forty meters high.
The entrance to the underground space of the World Tree and the location of the scarlet crystal is at the highest point of the core of the World Tree!
At the highest point of the core of the World Tree, there is a hole about the size of a wellhead.
The entrance of the cave does not go straight down vertically, but instead rotates downward like a spiral slide.
The entrance to this "spiral slide" was discovered by Zeng Tao.
Because she was very curious about the World Tree Core that was emitting scarlet light, she stuck close to it and looked at the translucent interior of the World Tree Core.
Then, she saw that there seemed to be a part inside that looked like a DNA helix and was more opaque than other places.
So everyone climbed up to the core of the World Tree with great effort, and the entrance to the "spiral slide" was discovered.
But because the passage was rotating downward, people could not see clearly whether it led to the bottom.
The one who tried to go down from this entrance was Xu Ying. After all, she had the ability to teleport through space. Even if there was danger below, she could teleport directly up.
So, Xu Ying went straight into the hole and slid down along the "spiral slide" which was the core version of the World Tree.
"I didn't go down directly, but stopped at the exit." Xu Ying said, "Because... right below the exit is the scarlet crystal."
Less than ten meters below the exit of the World Tree's core passage is the huge scarlet crystal.
The scarlet crystal was very large. Just as the monster said, it was about the same size as a three or four-story tree house. Although it looked relatively smooth overall, it had some potholes and its shape was irregular.
One part of it is clearly concave, with a large piece missing, and the entire piece has very uneven block-like cutting marks.
It is obvious that the damaged area was caused by continuous cutting over the past thousand years.
At the same time, Xu Ying saw that at the broken position, there were two alien invaders using some tools to manually cut the scarlet crystal.
"You actually saw alien invaders cutting crystals." Xu Xin said in surprise.
However, it seems normal that Xu Ying happened to run into him.
The alien invaders are now in great shortage of cut scarlet crystals, so much so that they need to recruit new staff members. The alien invaders who were originally responsible for this task will naturally continue to work.
"They are covered in a transparent, raincoat-like film, and use special cutting tools to cut the scarlet crystal."
Xu Ying recalled, and then rubbed her temple in annoyance: "Unfortunately, I was illuminated by the scarlet crystal's light that was almost blinding. I only observed it for less than ten seconds, and I felt like my head was going to explode, so I quickly teleported up."
She sighed, "To be honest, if I hadn't been in the World Tree Core and affected by it, I wouldn't have been able to hold on for even ten seconds. If only I had been able to snatch those equipment from those alien invaders."
"Alas, we couldn't help much at the time." Wen Guixin sighed, "Now there is a big problem. Although we have found the scarlet crystal, it is still a problem how to destroy it. We can't even get close to it now. Even being exposed to it for a few seconds will be very uncomfortable."
Xu Xin, Li Wenxi and the other two looked at each other and then laughed.
"What are you laughing at?" Xu Ying was a little dissatisfied, then she understood something and her eyes lit up slightly, "Could it be that you..."
"Yes, we have gained a lot here." Li Wenxi said with a smile, "It is exactly what we lack."
Xu Xin turned the bracelet and took out the two kinds of supplies.
Xu Ying stood up immediately and said in surprise: "This is... this is it! How did you get it?"
The others were also very surprised.
Xu Xin briefly recounted the thrills of their trip.
"... So that's how it is." Xu Ying muttered to herself, her hands unconsciously grasping the corners of her clothes, "In other words, we now have... a plan to destroy the scarlet crystal?"
"That's right." Xu Xin nodded, "This plan only uses the weapons we already have."
Xu Ying's breathing became heavier for a moment, and then she smiled bitterly: "Brother, you are giving me hope..."
"I'm not trying to give you hope, it's just the truth." Xu Xin said softly, "We don't necessarily have to use the weapons you brought."
"Huh? So, Yingying doesn't have to risk being wiped out of this world when using weapons from another time and space?" Wen Guixin said with some surprise and joy.
"… This is just a plan." Xu Ying took a deep breath, bit her lip and said, "If the plan fails, I still have my weapons to back it up."
"Yes." Li Wenxi nodded. "If the plan fails, it won't be too late to consider weapons from another time and space."
"Now that the plan has been finalized, we shouldn't waste time here."
Time is precious.
I don’t know how Ji Chaoyang and the others are doing, and how long they can hold on.
Hope they can hold on longer.
"It's time to go."
