"What does it feel like to be trapped outside the boundary wall of the world?" Lu Wu suddenly asked Amber after making the call. He had asked several times about something similar.

"It's hard to put into words......" Amber's answer was pretty much the same as the last time. "That's a pretty dangerous thing to do, though. In a way you can understand, it's constantly being washed by turbulence...... If it takes too long, it can become dangerous. There are also oceans on Earth...... It's like swimming in the ocean. It's okay for a short time, but it's very dangerous in the long run. ”

"Why is it dangerous? It's like a boat being pushed away by the waves, and it's going to get lost?" Lu Wu remembered that Amber had said that the magical world he came to also had an ocean. Where there is an ocean, there must be a boat. "Or will you be unable to hold on because you are physically exhausted?"

"Worse than that, it will be destroyed. Amber said. "The kind that was torn apart. By the time the strength is exhausted, it will definitely be like this. I'm glad I met you. ”

"That's why it's important to go to Earth...... Wait, you've been waiting outside the wall for a long time, right?"

Although the Holoera box did not have a manufacturing date when it was first obtained, it has been sitting in the supermarket for quite some time based on other indications, including the thickness of the dust on the surface of the box. Considering the factors such as production and transportation, it must have been some time before it entered the supermarket. I don't dare to say how long, but there should be half a year and a year.

"It's been a long time. Amber admitted. "It's longer than I've been to Earth. ”

"So, as a traveler in time and space, why don't you return?" Lu Wu asked softly.

"Ah, this ......"

"I don't know what your world is like, but on Earth, if you encounter danger when you go on a trip, you will definitely return. Even if there is a beautiful scenery ahead, your own safety always comes first. ”

"This ......" Amber's voice was a little frightened, as if she was afraid of something. However, I can feel that this fear is not the kind of outright fear, because it is mixed with a strong unwillingness. "There's no going back. ”

"Why?"

"War. Amber replied in one word. After a few seconds of silence, he continued. "Now, a powerful enemy is chasing me from behind, and if I hadn't been hiding in this 'fold', I'm afraid I'd have already caught up.

"Are you...... Fugitives?" Lu Wu was taken aback.

"Of course not!" this time, Amber firmly denied it. "It's just that we ran into an enemy on the way. ”

"So you're not a simple traveler, are you?" Lu Wu asked. "If it's just for the sake of traveling, if it's for the sake of gaining knowledge, this shouldn't happen. ”

This is the obvious logic, because if one is in danger, one will never have the time to travel and expand one's knowledge.

"That, that ......" Amber's voice seemed stumbling.

"If you are not a simple traveler, then you have risked your time and space to come to Earth...... It should be a picture, right?" Lu Wu felt that since the topic had reached this, it would be better to make it clear.

To tell the truth, if Amber is really the vanguard of the invasion of the other world, then although reason tells him that Amber's success or failure will not change the overall situation - at most it is only ahead of schedule or lag behind - but Lu Wu will never want to let the invaders enter the earth by his own hands.

But then again, there shouldn't be such a stupid invader in the world, right? Because Amber has made it clear that she needs Lu Wu's help, and it's the kind that is urgently needed and necessary. Normal logic, if Amber is a cunning aggressor, then he should repeatedly hint that "you can really speed things up if you help, but I can do it myself without your help" so that is right.

"......" Amber didn't answer, he was silent for a long time.

"That, Lu Wu, I'm sorry, I lied. I am not a mere traveler. ”

I don't know why, hearing Amber's words, Lu Wu immediately felt a stone in his heart fall to the ground.

"Actually, you're right, I came to Earth...... Although it was an accident. Amber seemed a little downcast, but it didn't seem to be anything. "But the trip itself has a purpose. To put it simply, I hope to get something out of the earth. ”

"Some...... Stuff?"

"It's materiel. Our World...... Things are not going to be good right now, so I'm hoping to get some supplies from Earth. ”

"Your world...... What's going on?"

"Our World...... Wag, the war is going on. Just like what you told me about the Earth, the humans of Earth have invented the atomic weapon that can destroy the Earth. But anyway, the human race on Earth hasn't used it yet, has it? And our world is one step ahead of the Earth in this regard. Amber's words smacked of self-deprecation. "The war to destroy the world has already begun. ”

"What do you mean...... Emigrate to Earth......?" The Huns drove out the Ostrogoths, the Ostrogoths drove out the Visigoths, and the Visigoths drove out the Romans......

Can the earth survive the magic of another world? It must be dangerous......

"Migration to Earth? How is this possible. Amber was surprised by Lu Wu's judgment. "The comings and goings between different worlds...... The forces needed are enormous. Even if Wago really perished, only a handful of people would be able to escape to another world. And even if you run away, you won't run away to a place like Earth...... How can I say such a depressing thing, Wago is still very early to perish! Our world will not perish!"

"That'...... What does it have to do with you coming to Earth?"

"The basic fabric of space-time in our world is disintegrating," Amber said. "A ...... The ultimate way of destroying the world. If the basic structure of a world collapses, nothing will be left. I came to Earth to get something that would compensate for the collapse of time and space. ”

"Make up for the disintegration of time and space...... "Well, although Lu Wu is a college (graduate) student, but when it comes to imagination, at least he can't imagine what kind of scene the disintegration of time and space is. However, the word itself, as well as Amber's commentary, made him understand that this was probably a terrible thing.

"What do you want on Earth?" Lu Wu asked. He intuitively thought that if the other world needed to take some special element from the earth to make up for the shortcomings of the other world, would the earth also fall into the disaster of space-time disintegration?

"It's not certain yet. But this should be something that doesn't matter to the planet. The structure of the Earth's space-time is very stable, especially the boundary walls. At least for the foreseeable future, there is absolutely no danger of the fabric of space-time collapsing. Therefore, this matter should not cause any damage to the earth. That's what I want to do on Earth, because there are very few worlds like Earth that are solid. ”

……

W City, on the edge of the industrial park, a medium-sized warehouse.

The time is early evening, a safest time. At this time, normal people were eating dinner, and the warehouse was empty.

Lu Wu stood in this warehouse that he rented, looking at the twelve generators he had bought in the huge warehouse. Although each generator is quite large (by the standards of a generator), it is not enough to put it in this warehouse with an area of hundreds of square meters.

It's not that Lu Wu doesn't want to rent a smaller warehouse, but there are no small warehouses around here at all. Of course, he could have chosen those houses that were nominally warehouses but were actually private houses. However, due to the safety and noise issues, the warehouse in this industrial area was finally chosen. Only here is the problem of everything not a problem.

Earthlings may not understand magic, but earthlings are not fools. This kind of thing that summons another world must not be seen.

In China in the 21 st century, as long as there is money, the efficiency of work is absolutely first-class. The owner of the warehouse was almost impatient to sign the lease contract and collect the money, and the generator factory (yes, the local production in W City) quickly brought in the generator truck. Even the little things like oil and wires are all covered by the people in the generator factory.

In these years, merchants are only afraid of not making money, not trouble.

In addition, Lu Wu is now also a shotgun changer. He brought a portable WIFI, and Amber can communicate anytime and anywhere.

Generators roared, and through the connection of wires, hundreds of times more electricity than normal residents used was gathered on the sockets. When Lu Wu inserted Holoera's plug in, his fingers couldn't help but tremble.

If it is an ordinary electrical appliance, it will definitely burn out immediately under the impact of such a strong electrical energy, making a "bang" sound and a burst of stench of burnt plastic. But Holoera didn't respond. Electrical energy is being transmitted in a way that is not yet understood by earthlings, from the fragile wires of electrical appliances into another dimension.

There were no gorgeous and fantastic scenes, no lights, black holes, and the like, but with a slight "click" sound, a figure appeared in front of Lu Wu's eyes.

From the time he realized that he had really met a traveler from another world, Lu Wu had always fantasized about what this person was like. When he found out that the other party was from the wizarding world, he became even more curious.

Although Amber claims to be human, she doesn't say if there is any difference in appearance between those magicians and ordinary people. Truth be told, if there really were magicians in the real world, it would be normal to say that ordinary humans were any different. Well, at least from Lu Wu's point of view, as long as he maintains a general human shape, even if he has an extra tail, an extra pair of horns or something, it is normal.

But in fact, what appeared in front of Lu Wu was a person he couldn't have dreamed of.

"Whew...... Call...... It's finally here! This is Earth? What a strange place!"

If before the telepathy was a whisper close to the ear, now the sound he feels is like a tweeter. Even the noise from the simultaneous roar of a dozen or so generators couldn't interfere with it - well, the sound was indeed directly in his head, and it was not affected by the noise at all. It was also this that made Lu Wu understand that he was indeed not mistaken.

"You...... You ......"

The one in front of him is a mysterious magician from a magical world, a time-traveler named Amber.

"Are you...... Female?!"

That's right, at this time, there was a girl suspended in front of Lu Wu.
