Are you too tired to move, are you hallucinating? Lu Wu looked left and right, and the door was locked. He even opened the door and went out to take a look, making sure there was no one outside.

Lu Wu walked out of the room, came to the bathroom outside, and washed his face. Then go back and start packing your bags. He didn't have many things, mainly clothes and quilts and mattresses. It is more troublesome to tidy up alone, but it is not difficult......

"Hey, that...... Can you hear me?" the voice sounded again.

Damn, how are the auditory hallucinations so weird now?, he walked to the window and looked out at the river. At this time, a flat-bottomed transport ship did not know what goods were passing through the small river, and the sudden sound of the motor was accompanied by the sound of brushing water, which was quite loud. Lu Wu stared at the ship until it disappeared from view.

The voice didn't come again.

Lu Wu took a long breath, and sure enough, everything was an illusion. In fact, he shouldn't be surprised that he is too tired recently because of a series of things like graduation, job search, and moving. Especially the mental stress is very high. As one scientist said, the human body is a delicate machine. Overstrain injuries are sure to cause all sorts of breakdowns.

"Hey, did you hear me. ”

This time, it's even worse. Although Lu Wu denied this matter in his heart, he was actually waiting for the voice to sound again. He finally determined that it was not his ears that he "heard" the voice, but a voice that sounded directly in his head.

Worst...... Is it schizophrenic? Is it really so much stress on me to find a job and rent an apartment?

Lu Wu had heard of this mental illness. He also knows that schizophrenia can present with a variety of perceptual disorders, the most prominent of which are hallucinations, including auditory hallucinations, visual hallucinations, olfactory hallucinations, taste hallucinations and touch hallucinations, with auditory hallucinations being the most common. Although there is no scientific explanation of the cause of schizophrenia, at least everyone knows that external mental stress is definitely one of the triggers. In a more popular phrase, human beings can be driven crazy.

No, it shouldn't just be mental stress, there should be something else.

He walked to the router with some irritation. It is said everywhere that electromagnetic radiation has a great adverse effect on the human body, and even some people would rather have no signal on their mobile phones than dismantle nearby base stations. Lu Wu decisively turned off the damn router - this thing is an old thing that has been used for many years, and generally speaking, the radiation of old electronic products always exceeds that of new products. After all, the theory that electromagnetic waves hinder health was far less popular than it is now.

Then he sat down and waited for the next auditory hallucination. If it is schizophrenia, he must at least know how the split "self" appeared and what he wants to do.

Minutes and seconds passed. After a long time, the voice did not sound again.

Really...... The situation is not as serious as I thought. Occasional auditory hallucinations and persistent auditory hallucinations are two different things entirely. The former is something that everyone can encounter, but the latter can be seen as a symptom of mental illness.

Wait a minute...... Auditory hallucinations...... Router......

A thought suddenly popped into Lu Wu's mind. It seems to have been fine all along, but suddenly this sound appeared after the router was installed.

This router was used in the dormitory before. But then again, electromagnetic waves are also affected by the external environment. For example, the house he lived in used to have brick walls on all sides, but here it has that kind of plastic panels. Could it be that the reflection of plastic plates causes electromagnetic waves to concentrate and ultimately cause adverse effects on the human body?

The idea was ridiculous, but it stuck in my mind and wouldn't leave. Lu Wu finally turned the router back on.

"Hey, hey, hey...... Can you hear ......" As soon as the voice sounded, Lu Wu immediately turned off the router.

The effect was so obvious that the sound was only halfway through, but as soon as the router's power indicator went out, the "sound" disappeared immediately.

Sure enough, it has something to do with the router!

Lu Wu turned on the router again. What happened next was exactly the same as it had just happened. Every time that sound sounded, he immediately turned off the router - and the sound stopped abruptly.

After trying this three times, Lu Wu was sure that everything was a problem with the router. As soon as the router is turned on, that wonderful sound will ring in his head, and on the contrary, as soon as it is turned off, everything will be back to normal.

Oops, it's really a bad influence of a particular environment. Doesn't that mean...... This router doesn't work?

On the Internet, the price of routers is generally between 100 yuan and 400 yuan (depending on performance), but this place in W City is very dark, and the routers in several markets are more than 150 yuan.

But it looks like I'm going to have to buy one. Hey, forget it, order one online. Fortunately, there is Taobao in this year. Although it is said to be two days late, it is better than going to the computer market. It would take half a day to go to the computer market.

Lu Wu turned on his phone. Now mobile phones are more convenient than computers, and in a few clicks, he found the webpage to buy a router...... Wait a minute...... Snap shot?

That's right, a rare opportunity to grab a shot. Routers that were originally worth hundreds of dollars are now sold for only ten yuan. The snap time was about ten minutes later.

Ten minutes...... Lu Wu immediately made a decision. Relying on the pitiful network speed provided by China Mobile, it is impossible to grab it. But if the router is turned on, then he can give it a try. You might be able to grab this router for almost no money.

As for that strange auditory hallucination...... Well, it should be fine in a few minutes.

Around the same time, he turned on the wireless router.

“…… Do you hear that? Please...... When I hear it, I say...... "This auditory hallucination in my mind really looks like that, and it's actually a tone of prayer."

"I hear you, don't make a noise, I'll turn it off soon. Lu Wu said casually.

"You really heard it!" In the next moment, Lu Wu clearly heard the joy contained in that voice.

"I know you're hallucinating, but please don't harass me just yet. Lu Wu said while staring at the timer on the phone screen. "In a moment, in a moment, I'll turn off the router. ”

"Router? What is a router? Since you heard me, why didn't you answer me? What is this place?"

"Earth. Lu Wu already regretted it a little, he shouldn't have talked.

"Earth???Haven't heard of it. The voice in his head said. "But by all means, please help me. ”

Lu Wu's hand trembled. At this time, it was time to snap the shot, but his hand didn't press the snap button on the phone screen.

Wait, things seem to have changed? Help me? It's not like what a second personality would say after schizophrenia.

"Help you?" Lu Wu raised his head with some hesitation. As mentioned earlier, this is the house he just rented, almost all four walls, and there are few different furniture. Lu Wu didn't think that there could be anyone hiding in this place. If you want to say that this is a yin house, there was once some unjust ghost buried, and so on, it's not like it. After all, this house is not very old, probably built in the nineties of the last century. But could it be that the house was built in an inappropriate location (let's say an ancient tomb)?

"Are you unjustly killed?" he asked, not very confident.

"No, I'm not a ghost, I'm ...... Traverser!"

"Traverser?!" Lu Wu was shocked. Crossing is a popular topic now, and there is an endless stream of related novels, TV movies, anime, and so on. But that's an imaginary thing after all. For ordinary people, it is definitely a good dragon-type thing for Ye Gong. If you meet a time-traveler in the real world, you will definitely be shocked.

"Are you...... Future people?" Lu Wu asked hesitantly.

"I came to this world from the other side of time and space, but now something has gone wrong and I'm stuck on the edge of this world. The voice continued. Lu Wu's mobile phone screen showed that the auction had ended, and the ten routers that were pushed out by the shopkeeper for the auction were robbed in less than a second. But now Lu Wu has no intention of paying attention to this.

"My name is Amber, please help me. I'm in danger here......"

Amber...... The name...... Lu Wu now really believes that he is not schizophrenic, because he feels that no matter how schizophrenic he is, he will not give himself such a name. At least according to Chinese tradition, he does not change his surname.

If he is not schizophrenic, then ...... Did he really meet a traverser? This world is so big, how could he meet it? Wait, the traverser's words......

At least with the realistic technology of the earth plane, it is far from being able to do such an awesome thing as "traveling through time and space".

The latest technology on the ground, the controllable nuclear fusion reactor, is no longer in terms of scientific theory, but the specific technology has been studied for so many decades, and it is still "the revolution has not yet succeeded, comrades still need to work hard", and even when it will succeed is still far away. And time and space travel, not to mention technology, even the basic theory of the front is not half a hair. For example, interstellar travel, this technology tree is more complete, both theoretical and practical technology, and even earthlings have launched a lot of space machines. But so far, aerospace has still not been able to really realize it because of cost performance.

Lu Wu subconsciously remembered the many online novels he had read, which told how the time-traveler changed the world with the help of technology and the advantages of the times. Well, as nonsense as these stories are, when a real time-traveler appears in front of you, you naturally think of these things.

Obviously, if an alien fleet appears in Earth's orbit, then any sober-minded earthling knows that the aliens must have more technological power than the Earth. Because the technology of the earth is not yet able to do such a thing as "building a space fleet for space navigation".

In the same way, if a time-traveler appears on Earth, then this time-traveler must have technology and knowledge that cannot be matched on Earth. And so on, maybe it's not technology, it's magic, or whatever, but it's something that isn't currently available on Earth, or hasn't been discovered by scientists.

Although Lu Wu has always considered himself an atheist, if a real time-traveler appears in front of you with irrefutable evidence, it is very common to change the three views. As a philosopher once said, it's easier to admit that the whole world is wrong than to admit that you're crazy.

After he was really, unquestionably convinced that he had met a traverser, countless thoughts flashed through Lu Wu's mind. Most of them involve some anime and fiction content.

If you can get the knowledge and skills of another world that you don't have on Earth from the travelers......

This thought alone makes people's hearts beat uncontrollably. If a medical test is carried out at this time, then Lu Wu believes that the frequency of his heartbeat will definitely make the old Chinese medicine and Western medicine doctors dumbfounded.

This should be regarded as the so-called "God closes a door, but opens a window". At this moment, the original confusion, uneasiness and frustration in Lu Wu's heart have been swept away.
