Her words immediately gave the explorers a greater sense of security.
"So the strength of the World Tree after maturity is so strong!" Wang Lei said in surprise, "Then aren't we basically invincible?"
"No wonder those guys came in droves like crazy, not wanting the World Tree to mature," Wen Guixin complained, "But after the World Tree matured, it's been so long, and there's been no movement at all."
"Not long." Xu Xin reminded, "Only more than three hours have passed outside."
"Ah... This time flows at a different speed. It's really hard to get used to it."
Qin Yunlong on the side said: "But this hundred times faster time flow really makes us much more relaxed."
The time flow rate was a hundred times faster, which made the explorers' tense hearts relax a lot after arriving in this world.
Even if you spend a whole day doing nothing, only a dozen minutes pass outside.
When you think about living here for a hundred days while it only takes one day outside, everyone's originally very tight pace of life will naturally slow down.
There's still plenty of time, why rush
This is the most normal thought in their minds now.
But... there is still a thorn that has been stuck in their hearts, making it impossible for them to truly relax.
"So how do you plan to solve the problems in the underground world here?" Ji Chaoyang asked Xu Ying.
"Hmm? You mean the technology and people of the underground world? I can leave now, but I still suggest you develop this place first..."
"That's not what I'm talking about." Ji Chaoyang turned his eyes to Xu Xin, "You didn't tell her?"
"Ah... not yet." Xu Xin said a little embarrassedly, "In order not to waste time in the outside world, I brought them in as soon as they came back. I haven't had time to say anything yet."
"What? What are you talking about?" Xu Ying looked at them blankly, and then said to Li Wenxi, "Sister-in-law, do you know?"
Li Wenxi also shook his head blankly: "What can I know..."
Li Wenxi knew basically nothing about either Xu Xin's or Xu Ying's information.
She had been digesting this information since just now, and her mind was so confused that she couldn't sort it out yet.
Seeing Xu Ying looking at her inquiringly, Xu Xin pointed to the ground and said, "Directly below the World Tree, there is an underground sea world area with a radius of two to three kilometers. It will also be affected by the speed of time inside the World Tree."
"…Will the underground world also be affected?"
Xu Ying was slightly stunned, then thought for a while and said, "Well... The World Tree is indeed connected to the underground world, and it makes sense that it can affect the speed of time underground."
Then, her eyes lit up slightly: "This is actually good news for us."
"Although the time flow rate inside the World Tree is a hundred times faster, there are basically only soil and water resources, and other resources are very scarce. If you go outside to collect resources, the efficiency will be very low, but if it is the underground world area..."
The more she spoke, the more her smile grew, her eyes curved into crescents: "It's perfect! The various exotic and scarce resources in the underground world are much more abundant than those on the ground, and there are even... crystal mines that can be mined!
With the time flow speed increased by a hundred times and my sister-in-law's ability, we can collect as much as we want!"
That's a good point.
Xu Xin had considered this before, but...
"There are other things underneath!" Zhao Xiaochuan said, "There are scary monsters everywhere. They can't be easily used, right?"
"You probably don't know the situation underground here, right?" Xu Xin also asked.
"Of course I know the situation in the underground world. The situation underground in your entire survivor area is similar."
Xu Ying glanced at the ground and said, "I've seen giant beasts, giant insects, and giant plants everywhere before. They're all caused by those alien invaders. But don't worry!"
She raised her head and looked at everyone: "Since the speed of time in the underground world has also been changed, that area can be regarded as the inner space of the World Tree. And in this space..."
She walked to Xu Xin's side, hugged Xu Xin's arm with a smile, looked at the others and said, "My brother and I are invincible! Don't forget, we are the owners of the World Tree, this is our territory!"
...Yes!
Xu Xin's slightly frowned brows slowly relaxed.
Almost forgot this.
The area of the underground world is affected by the World Tree, so he is equivalent to the landlord there!
The explorers also reacted and looked at the brother and sister in surprise.
"But... our underground world is not that simple."
Xu Xin told Xu Ying everything about the vine bundles, the petrified creatures, the huge prison, the huge, soft beast beneath the prison, and the blood-veined python.
Xu Ying had no interest in petrified creatures and even looked down upon them.
She felt that those things would have no effect on the World Tree.
But when she heard the word soft beast, her expression changed slightly.
"Are you sure that an extremely huge, soft-bodied beast is trapped underneath?" Xu Ying asked again with emphasis.
"Of course we are sure. We were all scared at the time!" Wang Lei added, "Once you step in, you will sink right in. The moment you realize it's a living thing, it's really creepy!"
As he said this, he touched his arm in a very vivid way, and goose bumps appeared on his body.
"That's really..." Xu Ying could no longer hide the excitement on her face, "Great! I didn't expect it to be right down there!"
Oh
It seems that this is still a good thing.
"What exactly is it?" Xu Xin asked.
"Well... it's a bit complicated to explain, let's take action first!" Xu Ying thought for a while and said.
She let go of the hand that was holding Xu Ying's arm, grabbed his hand, and said with a smile: "Come with me, ah, sister-in-law, you come too, let's go to the underground world together now."
"Ah? Go down now?" Li Wenxi was holding Coco, and before he could react, Xu Ying grabbed his hand.
Xu Ying grabbed one in each hand and stomped her foot lightly, and a purple-black vortex instantly formed under her feet.
"Ying!" Keke screamed and quickly jumped out of Li Wenxi's arms and landed on the ground, as if she was running away.
Before the explorers could react, the three of them fell into the whirlpool and disappeared on the spot.
Everyone in the tree house was left looking at each other in bewilderment.
"Teleportation ability?" Zhao Xiaochuan asked in surprise.
"Is it similar to Shi Wanyun's ability? It seems to be more convenient than Shi Wanyun's, and does not require drawing teleportation array patterns." Wen Guixin squatted down and touched the ground.
"It's normal for someone from another time and space to have this ability." Qi Xuefei looked calm.
"By the way, did we forget to ask Brother Xin and his sister to give us permission?" Wang Lei complained, "We still can't get out now!"
"There's no need to go out for now." Qin Fu smiled as he sat on the sofa. "It's going to be a long day, right? Anyway, we have plenty of time, so why don't we enjoy it and make plans for the next step later."
“Hmm…” Coco lay on the side, opened her little mouth and yawned, glanced at the place where Xu Xin and the other two disappeared, and began to doze off again.
Ji Chaoyang was looking out the window.
At this moment, his eyes were dull and without any focus.
Then, there was a flash of light in his eyes.
As the light faded, he took a deep breath, his face showing a hint of fatigue.
But there was a hint of solemnity and shock in his eyes.
He was just prophesying.
The previous prophecy has come true, which is the arrival of Xu Ying and Li Wenxi.
So he immediately made a new prophecy.
His ability to predict now is basically stable enough to predict the next day.
But now there is a problem.
Will the scene he predicted this time happen on the second day inside the World Tree or on the second day in the outside world
If it was the second day inside the World Tree...
Then... there will be big trouble soon.
…
At this time, Xu Xin and the other two were already standing in the underground world.
Li Wenxi was the first to exclaim: "Oh my god, this bug is so big!"
This was the first time for Li Wenxi to come here. Although she had heard Xu Xin talk about their experiences in the underground world, she was still extremely shocked to see this scene of demons dancing wildly in person.
"I didn't lie to you." Xu Xin said with a smile.
"Yeah, it's really exaggerated..." Li Wenxi looked at everything around him and nodded blankly.
"This is actually the norm in this area," Xu Ying explained to Li Wenxi. "There are strange mutant giant plants everywhere. They are all caused by the endless experiments of the alien invaders."
As she spoke, she looked into the distance.
“Oh…! As expected.”
She also saw birds flying at a snail's pace in the sky.
"The flow of time has really been affected..."
"It feels really different to see it with your own eyes... Wait, if there are giant beasts here, what about the human base?" Li Wenxi turned his head suddenly and looked at Xu Ying, "Will these giant beasts..."
"No." Xu Ying shook her head and said, "The underground world occupied by the giant beast experiment is not that large. Our underground human base is half a planet away from here and is not affected by this side."
"But it was also affected by the attack of the mutant creatures, wasn't it?" Xu Xin said.
Xu Ying briefly told him about this last time, and he still remembers it clearly.
"Yes, but those are relatively small mutant creatures. They are easier to reproduce and spread, which is why they affect human bases."
Xu Ying nodded.
"These big ones are all experimental individuals, and their reproduction speed is also very slow. The biological resources in the underground world are not very abundant now, and there is not enough to create these giant beasts for large-scale expansion. Therefore, most of the mutants that affect the underground human base are smaller in size. Of course, this is only relative to them. Compared with those tiny mutants on the ground, the mutants that attack the underground human base are still much larger."
Xu Ying pointed to the huge monsters in front that looked like alien creatures.
"The closer we get to that big vine over there, the more giant beasts there are." Li Wenxi stared at the very conspicuous vine bundle in front of him. "The giant beasts near that big vine bundle are really fighting. So the prison you mentioned is below, right?"
"That's it." Xu Xin nodded.
"It looks so oppressive..." Li Wenxi sighed and turned to look at Xu Ying, "What should we do now?"
"Hmm..." Xu Ying touched her smooth chin, "Sister-in-law, use your ability to explore the surroundings first to see how rich the resources are."
"Resources?" Upon hearing this, Li Wenxi immediately activated her detection ability.
Then, her eyes suddenly widened, and she covered her mouth and exclaimed, "So many! So many! This is too much!"
"A lot, indeed a lot!" Xu Ying couldn't help but smile wider, "I told you, the resources here are definitely very rich."
"Is it easy to mine?" Xu Xin's eyebrows jumped and he asked hurriedly.
"Well, it looks like it's easy to mine!"
Li Wenxi looked around, then looked down at her feet, her almond-shaped eyes wide open, with doubt and lack of confidence in her tone: "Is there something wrong with my ability? What's going on... Why are there so many of them..."
Everywhere...
"Are there metal mines under our feet?" Xu Xin followed her gaze and looked towards the ground.
"Well, at least that's what my ability tells me, and... the location is very shallow, we only need to dig about two meters down...!"
Li Wenxi licked his lips, his eyes shining, and took out a shovel and a pickaxe directly from his backpack.
"Hey, wait a minute, sister-in-law, don't dig now, let's solve the situation here first." Xu Ying quickly stopped her, "The resources are here, they won't run away. But now there are giant insects and beasts everywhere."
"Oh, yes." Li Wenxi quickly put away the tools and looked at the three or four meter long giant caterpillar crawling not far away. He moved closer to Xu Xin with a little fear.
Regardless of whether this bug is strong or not, this thing is really disgusting just by looking at it!
"Don't worry. Those bugs usually don't attack people." Xu Xin comforted, then turned to look at Xu Ying, "So, what should we, the two owners of the World Tree, do now?"
"Look up." Xu Ying pointed to the sky.
above
Xu Xin looked up.
The three thousand meter high dome of the underground world is already covered with the roots of the World Tree.
At first glance, the roots of the World Tree seemed to cover the entire underground world!
The moment he saw these roots, Xu Xin's heart moved.
"I can... control them?" he asked in amazement.
"That's right, just like how you control the roots of the tree house. Hey, watch me!"
Before Xu Ying finished speaking, the roots that had covered the entire dome began to wriggle!
"Hey...!" Li Wenxi shrank his neck, "It's a bit scary..."
It's a bit scary indeed.
It was as if there were a group of wriggling worms hanging on the dome, and they were a group of worms that were several meters thick...
At this moment, a root emerged from the tangled root system that covered the dome, extending downward at a rapid speed and stabbing downwards!
The speed is extremely fast, obviously exceeding the speed of sound!
The thick roots pierced straight down, and in just a few seconds, they pierced into the ground, becoming a three-kilometer-long root connecting the ground and the dome of the entire underground world!
"Bang!" The sound of roots piercing into the ground came late. The entire ground was shaking, and even made the three of them slightly unsteady.
The giant beasts and insects around were all shocked by the sudden piercing of the ground.
"Brother, you try it too." Xu Ying still looked up and pushed Xu Xin beside her with her hand.
"Okay." Xu Xin looked up and narrowed his eyes slightly.
Just like controlling the roots of the tree house, after he concentrated his mind, he felt that the roots of this world tree were like his limbs and could be used freely!
Another root fell from the sky and penetrated heavily into the ground!
The ground was shaking, and the giant beasts around even began to become agitated and panic!
"Let's continue!"
Afterwards, under the control of the brother and sister, thick roots continued to descend from the sky, connecting the dome and the ground of the underground world.
Soon, ten roots connecting the dome and the ground stood up in front of the three people.
"Alright, alright! That should be enough!" Xu Ying grabbed Xu Xin's clothes and tugged at them.
Xu Xin let out a breath.
So cool!
It feels so good to control such thick roots like controlling arms!
He felt that as long as he wanted, the root could turn a corner and stab the surrounding giant beasts, or even the vine bundle!
"This... Is this all caused by you two?" Li Wenxi was a little stunned.
"It feels great." Xu Xin turned his head and looked at her and smiled.
"How can I not feel good!" Li Wenxi looked at the roots that pierced the ground like tofu and swallowed, "No wonder Yingying said you were invincible. Even this giant beast couldn't resist..."
"Okay, now there are ten of them, that should be enough." Xu Ying nodded with satisfaction, "Next, let the roots of the World Tree begin to spread underground in this underground world!"
“Although it cannot spread as widely as on the ground, the root system covers this affected area, so there is no problem!”
