Chapter 572 Brother and Sister Meet

At this time, the human base of the underground world.

"Huh...?" Xu Ying suddenly let out a little snort, her eyebrows raised slightly.

"What's wrong?" Li Wenxi turned to look at her.

The two are resting in the villa now.

They just contacted Wei Shishi and explained the situation to her, hoping to use the Wei family's military equipment to fly up to check it.

It's a pity that Wei Shishi didn't directly agree to them.

The current head of the family is still Wei Bai, and Wei Shishi does not have the authority to use advanced military equipment here.

It's okay to say it's in other places, but this is the hinterland of the human base. Using military equipment here to fly near the dome at a height of two to three kilometers will be very eye-catching.

Especially since there are two other big families watching over here, you have to be more careful when doing this kind of thing.

So Wei Shishi had no way to agree to them immediately.

She told the two that she would convince her grandpa when her grandpa came back.

Therefore, the two who couldn't do anything for the time being returned to the villa, waiting for news from Wei Shishi.

But neither of them could sleep.

It happened to be almost morning time, so they simply didn't sleep, and the two of them started eating.

And at this moment, Xu Ying let out a small sigh, and slightly raised her head to look upwards.

"What's wrong?" Li Wenxi also followed her gaze.

There is only the ceiling.

"Hmm... is it true? It's so easy to find?" Xu Ying blinked, "The entrance is hard to find, isn't it? Could it be because of the little panda?"

"Little panda? Do you mean Keke?" Li Wenxi was very concerned about Xu Ying's words, "What's wrong with Keke?"

"Ah, it's okay, it's just..." Xu Ying looked at Li Wenxi, "My brother found the entrance to our place."

"...Really?" Li Wenxi's eyes lit up immediately, "So fast! How long has it been?"

"I also feel that it shouldn't be so fast..." Xu Ying rubbed her head slightly distressed, "If brother opens that entrance, the upper and lower will really be opened."

"Open the entrance? What do you mean?" Li Wenxi asked.

She didn't come down the normal way.

At that time, she was dragged by Xu Ying to a relatively hidden jungle, and before she could react, she went to the underground world and the villa in the blink of an eye.

At that time, she didn't pay much attention to it, after all, she was used to using the portal on the ground.

Of course, she still asked, "Is this a portal? The coordinates?"

"Ah... yes! It's the portal. It's very secret, otherwise it will be discovered." Xu Ying replied in this way.

But now it seems that it is not a teleportation gate, but Xu Ying's own teleportation ability.

So she didn't have much confidence in Xu Xin's ability to find the entrance to the human base.

But I didn't expect that they actually found it, so quickly!

one day one Night?

"Hmm..." Xu Ying pursed her lips.

"That's right... If it was before, even I could only use my own teleportation ability to travel between the ground and here. The two places are not really connected. But if my brother unlocks the mechanism that only me and him can trigger... ..."

The more Xu Ying said, the more worry on her face deepened.

"Then, there will be a normal passage between here and the ground that anyone can use?" Li Wenxi asked after taking the conversation.

Xu Ying nodded slowly: "That's right. If those alien invaders find out, it won't be very good."

"They... didn't they already know?"

Li Wenxi pointed to the top of her head: "If our guess is correct, didn't they already set up a teleportation device on the dome?"

"That's different." Xu Ying shook her head.

"The function of the teleportation device is a random and stable long-distance transmission. The main capabilities are in the 'random starting point' and 'stable'. Using the teleportation device to teleport, there is no need to use any place as the starting point of the teleportation, and there will be no risk.

But its shortcomings are also obvious. The transmission device cannot transmit in large batches, it can only transmit one by one, and there needs to be a period of time between each individual. I don't know the interval, but it should not be less than half an hour. This is also a compromise made for stability.

Therefore, even if there is a teleportation device here, there is no need to worry about the opponent's army coming through the teleportation device. The threat to this human base is not that strong. "

"Is that so, half an hour of cooldown? I really don't need to worry too much. Is it very stable..." Li Wenxi thought for a while, "The coordinates that Xu Xin will make, the transmission is also very stable? We have not had any problems with the transmission. "

"You talk about the coordinates. That's the master of our technology. It's very powerful." Xu Ying showed a slightly smug expression, "I'm also one of the researchers! But... it's not stable, you guys When you teleport for the first time, you will basically be dizzy and weak, right?"

"Ah, so it is true." Li Wenxi immediately recalled the situation at the beginning, "It's not just the first time, basically it takes seven or eight times to transmit it before there will be no side effects."

"Well, this is a kind of instability." Xu Ying nodded, "Moreover, not only must there be a starting point and an ending point, but the teleportation distance should not be too far. If it is too far, there may be problems, and the teleporter Lost in the chaotic space. But the distance of the teleportation device is very far, and it can even... cross the planet."

"Crossing the planet?!" Li Wenxi was immediately shocked, "So powerful! The alien's technology is so powerful!"

"It's indeed very strong. If it wasn't strong, how could it cross the galaxy and come to us." Xu Ying sat on the sofa and leaned her head on the back of the sofa. "I get a headache just thinking about going against them..."

Then she shook her head violently, sobered up, and explained to Li Wenxi again: "So, stability and long distance are the advantages of the transmission device, but its shortcomings are very obvious, so there is no need to worry too much."

"But that channel is different. That channel was left by my brother. It is a fast channel that allows humans in the underground world to move to the surface as quickly as possible. The ability to collectively teleport is extremely strong. If it is discovered and used in reverse after it is opened, …”

Xu Ying frowned slightly: "If you are not careful, this place will be destroyed."

"Hmm... don't worry so much, right? They all have the ability to install teleportation devices here. If they really want to attack in a big way, there must be a way, right?"

Xu Ying shook her head: "No, I don't think they have the ability to attack human bases now. Their permanent residence is very far away from here, but with an expedition spanning almost half a planet, it is not easy.

There may be a teleportation device here, which is most likely related to the invasion of mutated creatures that began a hundred years ago.

My guess is that that group of mutated creatures has been expanding in the underground world for thousands of years, and finally spread here, found this place, and let some bastard know about it.

So, that bastard sent someone to travel a long way here with a teleportation device, placed the teleportation device here, and then slowly penetrated and eroded the underground world. It is because they have no way to attack here collectively that they do this. "

"But if they have this method, I'm afraid something big will happen..."

The more she spoke, the more anxious Xu Ying's face became, and then she stood up suddenly: "No, I want to go up and take a look. I can't let my brother open this passage in advance!"

"This..." Li Wenxi also stood up, "Do you want to go up? If this passage is not opened, won't Xu Xin and the others have no way to come down?"

"It's not like it won't be turned on forever, but now is not the time to turn it on." Xu Ying stomped her feet slightly, and a purple-black vortex began to appear under her body. "At least we have to wait until the resources and weapons and equipment below are complete. The current human base area has no Even humans themselves can’t believe their ability to resist!”

With that said, she fell into the whirlpool and disappeared.

"It goes so fast..." Li Wenxi sighed, sat back on the sofa, and exclaimed, "I really want to be able to teleport so conveniently. The teleportation device... The teleportation device can actually travel across the planet..."

…

"Don't move." Xu Xin stopped Lou Fei'er from twisting the earrings of the stone statue, "Don't trigger the mechanism now."

"Huh?" Coco called out in confusion from the stone statue.

"Why, since we have found a method, let's open it first."

Although Lou Feier was a little unhappy, she still took her hand off the stone earrings.

But she didn't give up convincing Xu Xin yet: "Since it's similar to your statue, maybe there's a crystal city below? If we also activate the crystal city below, wouldn't it be stronger? Protect it. It would be easier to build a World Tree, right?"

Xu Xin opened her mouth, but in the end he still did not tell her the truth.

Although the entrance to the human base in the underground world is just his guess, it should be close to home.

The fewer people know about this, the better, otherwise there will be big problems if it reaches the ears of alien invaders.

"Huh?" Coco jumped off the head of the statue, jumped into Xu Xin's arms, tilted her little head in his arms and looked at him, as if asking Xu Xin why he didn't trigger the mechanism.

"This matter is not that simple. Moreover, we are also a team now. It is not a good habit to cover one's head. Some things still need to be discussed with everyone in the Explorer before taking action."

Xu Xin moved out everyone in the Explorer, and Lou Fei'er had no choice but to accept: "Well, it is true that the two of us are in some danger. It should be much safer if we bring a few more people."

"Bringing a few more people is even more difficult." Xu Xin objected, "Now we are in the protection stage of World Tree. How can we let the main force protecting World Tree do something that will take who knows how long?"

"Oh - what should we do?" Lou Fei'er looked at the statue, then looked at Xu Xin, "You don't plan to touch the statue, right?"

"At least let's wait until this World Tree siege is over." Xu Xin felt that he should be on the safe side.

First complete the current goal and protect the World Tree.

"Uh... Okay, okay." Lou Fei'er was a little disappointed and glanced at the statue itchingly, "Is it really just for a look? Okay, do you want to go back now?"

"Well, there shouldn't be anything else here..."

"Hey!"

Before Xu Xin could finish her words, Coco suddenly screamed and pointed her little paw in one direction.

Looking in the direction it pointed, I saw a faint... purple-black light coming from behind the stone statue with a human face?

"what's the situation?"

Lou Fei'er immediately flashed her figure, quickly came to the back, and looked intently.

"It's a purple-black vortex! Teleportation!" Her voice immediately became solemn, "Something is coming out of it!"

As soon as her hands touched her waist, she held two daggers in her hands, always ready to take action.

Xu Xin also ran over one step behind her and looked at the source of the purple-black light.

He did not draw his weapon.

Because, for some reason, he felt a little...excited and excited?

There was a sudden flash of purple light, and then, a figure stepped on the ground.

Lou Fei'er stood in front of Xu Xin at this moment and scolded the figure: "Who are you! Why... Huh?"

When she saw the man's face, the scolding in her mouth suddenly stopped and was replaced by surprise.

She immediately turned to look at Xu Xin who was aside.

He looked again at the girl who was leaning on the stone statue and looked very tired.

"It seems..."

The moment the girl appeared, Xu Xin's eyes immediately flashed with excitement.

He opened his mouth, not knowing what to say for a moment.

This girl...

She is his sister, but... not his sister.

In the end, he could only say two words softly: "Yingying..."

Xu Ying was very tired.

There were too many transmissions in one day today.

Moreover, teleportation from the underground world to the ground is not easy even for her. At the same time, she also needs to be careful not to be noticed when teleporting.

So when she came up, her head was slightly dazed. It took three seconds for her to recover slightly.

Then she heard a familiar voice: "Yingying..."

Her mind suddenly cleared.

She immediately looked past Lou Fei'er and saw the person she was very, very familiar with, Xu Xin.

At this moment, her eyes immediately turned red.

Although she knew that this Xu Xin was not her brother, the face that she was tired of seeing and the extremely familiar voice instantly made her chest feel clogged.

A person who had lost all her relatives and friends suddenly saw the face of her closest relative. At this moment, she really couldn't hold herself any longer.

Fortunately, she was also hundreds of years old. She took a deep breath, calmed down her emotions, and raised the corners of her mouth: "Hi, brother, long time no see. Have you missed me?"

Xu Xin looked at Xu Ying, who was obviously several years older than his real sister, and felt a little uncomfortable for a while: "You... look like you have really grown up a lot."

"Of course. I'm a survivor from the previous batch, and I'm older than you now!" Xu Ying didn't know that Xu Xin had already guessed her identity, and said with a smile, "Brother, you should call me sister. La!"

"The first batch of survivors..." Xu Xin immediately laughed, "Yingying, this should be... our first meeting, right?"

"Huh?" Xu Ying's eyes widened, "What do you mean...you, you know?"

Xu Xin shook her head helplessly and said: "Have you forgotten that I have seen you in the image? You are almost exactly the same as you now."

"Ah..." Xu Ying was a little embarrassed and scratched her head, "How come you and your sister-in-law guessed it?"

Lou Fei'er hugged Coco and stood aside without saying anything.

"Hey!"

Coco wanted to jump out of Lou Fei'er's arms, but she grabbed her and stopped her from running. She scolded her in a low voice, "When brothers and sisters meet, don't disturb them!"

"Hey..."

Xu Xin walked up to Xu Ying and said with a smile: "No matter how old you are, your temperament has not changed much."

"Brother..." Xu Ying's eyes turned red and she sniffed.

She looked at Xu Xin's overly friendly face and gritted her teeth.

In the end, she couldn't hold it back, suddenly stretched out her hand, hugged Xu Xin tightly in front of her, buried her head and cried loudly: "Brother, you died so miserably!!"

Xu Xin: "I..."

Lou Feier: "Pfft..."

Coco: "Huh...?"
