Magus Tech (Technological Wizard)

At this time, the old man said to Li Cha, as if he was judging a criminal: "Boy, have you realized that this is what you deserve for your arrogance, arrogance, insolence and cleverness! Your curiosity is too strong, try to To get close to something you shouldn't know, then it can only be - a painful death!

Let me tell you, mortals should not have too much curiosity, curiosity will only harm you! "

Speaking of this, the old man's tone suddenly changed again: "Of course, out of goodwill, I can give you a chance to reform yourself. You just need to promise that you will never be curious about things that you shouldn't be curious about, and don't explore what you shouldn't be. For those things, live a good life. Then I can use some means to remove the poisoned state of your body, and even give you a good leg. How about it?"

After listening to the old man's words, Li Cha's eyes flickered, and he looked at the old man, without speaking for a long time.

"What do you want to say?" the old man couldn't help asking.

Li Cha still didn't speak. He turned his head to look around, looked at his rotting body, looked at the calf that was cut off by himself on the ground, and finally looked at the old man again.

"All of this is illusory, right?" Li Cha's expression was quite serious, "Although I have been guessing, it is almost certain now. All of this is a very special kind of illusion, right?"

The old man was angry and shouted: "Nonsense! What an illusion, it's real! Why, boy, do you feel that you can no longer accept the reality? You can't accept it. Did you work hard to the end, but there was an extremely miserable ending? But This is reality, and this is reality brought about by your curiosity!

Do you think this is an illusion? Then tell me, where is the fake? Look at everything around here, feel your body, do you think there is anything unreal. "

"But I'm still skeptical." Li Cha said with a slight smile on his face.

The old man snorted: "But no matter how much you doubt, this is the real world!"

"Then—" Li Cha said, looked at the old man, pointed to the side, and said, "Can you stand there and talk to me?"

"Huh?" The old man frowned, "Why?"

"Because I found that since you appeared, it seems that you haven't moved at all, which is a bit strange..."

Before Li Cha finished speaking, the old man walked to the place Li Cha pointed at, stood in front of the wall at the end of the library, and said disdainfully to Li Cha: "Why, do you think I haven't walked around before, it's just an illusion , Do you feel that I am an unreal projection?

Oh, poor boy, accept it all, your body is mutilated, the poison is spreading throughout your body, and there is not much life left. If you don't ask for my forgiveness, you will die. "

"What you said seems to make sense." Li Cha nodded "deeply convinced", then looked at the old man and said, "The problem is, this is indeed an illusion. Although it is very special, I can't even realize what I am I was recruited at the time, and I didn't feel any mana fluctuations, although it imitated all the details without any problems, and I couldn't see any flaws with the naked eye, but... a fake is a fake."

"Impossible!" the old man shouted, as if he had lost his composure, "Is there anything wrong with this world, this real world? If your eyes can't find anything wrong, how can you say it's fake? , just relying on your imagination?!"

"Of course not." Li Cha shook his head slowly, "I have to admit that your methods are so superb that it is difficult for me to find flaws with the naked eye. But the problem is... I not only have eyes, but also other sense organs, such as ears .

You do imitate the current illusion very realistically, but you cannot imitate it, or you are not aware of the laws of physics. Therefore, in my perception, the current world and this library lack something that should exist.

"

"What?" the old man couldn't help asking.

"Echo!" Li Cha gave the answer.

"Echo?" The old man was stunned, puzzled.

"Yes, echo." Li Cha explained calmly, "When a sound wave is projected onto a large-area obstacle at a distance from the sound source, part of it will be absorbed, while the other part will be reflected. If a person, hearing the sound caused by the sound There is an obvious time interval between the sound directly sent by the source and the sound reflected back, and the difference between the two sounds can be distinguished, that is, an echo is generated.

Generally speaking, the shortest time for humans to distinguish the echo is 0.1 second, and the speed of sound propagation is 340ms in the air at 15 degrees Celsius.

It is now November, that is, the cold moon, and the temperature inside is relatively low at night, but in this library, the temperature is acceptable, about 15 degrees Celsius. The library is about 12.5 meters wide and 22 meters long. Where you are standing now, the distance from the farthest wall is more than 17 meters, about 20 meters.

The sound comes from your mouth and reaches my ears, and the time is basically negligible. But it takes about 0.12 seconds to get to the farthest wall, and then transmit back a 40-meter path, which is enough time for me to hear the echo.

However, I don't hear the echo. Whether it's making you change positions or prodding you to speak up, the echo is completely absent.

Obviously, this is an illusion, a very special but indeed fictional illusion. Everything, the insect, is made by you, and so is the sound, so there is no echo. "

The old man changed his expression little by little after listening to Li Cha's words. Although he didn't quite understand Li Cha's words, he was sure that Li Cha had really seen through his tricks, and his eyes were cloudy.

At this time, Li Cha looked at the old man and said: "Since it is an illusion, it will be much easier. Although I don't know the specific principle of this illusion, it should confuse my brain and generate wrong electrical signals. And my brain can Not really easy to control, especially after I realize it's a fake world."

"Then—" Li Cha made a sound, stretched out his hand and slowly grabbed the rotting skin on his body, dunked his fingers deeply, and then pulled hard.

"Stab!"

The skin is like a coat, it is ripped off, and there is no bloody flesh under the skin, but brand new clothes.

Then Li Cha bent down, picked up the cut off calf, and aimed at the incision to catch it. With a "click", the two were connected together as if magnetically attracted, and returned to their original state.

Li Cha nodded in satisfaction, stood up straight, and looked directly at the old man.

The old man's expression changed completely. Looking at Li Cha who had completely returned to normal, he had a premonition that he was out of control. A trace of panic flashed in his eyes, his lips pursed, and he subconsciously stepped back. ...
