At this time, the old man spoke out, as if he was judging a sinner and said to Richard: "Boy, you realize it. This is the end you deserve for being arrogant, arrogant, defiant and clever! Your curiosity is too strong, trying to Approaching something you shouldn't know will result in a painful death!
Let me tell you, mortals should not be too curious, curiosity will only harm you! "
At this point, the old man's tone suddenly changed: "Of course, out of good intentions, I can give you a chance to change your ways. As long as you promise not to be curious about things you shouldn't be curious about, or explore things you shouldn't explore. You have to live a good life. Then I can use some means to relieve the poisoning state of your body, and even give you a good leg. How about it? "
After hearing what the old man said, Richard's eyes flashed 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.
Richard still didn't speak. He turned his head and looked around, at his rotting body, at the calf on the ground that had been chopped off by himself, and finally looked at the old man again.
"All of this is an illusion, right?" Richard's expression was quite serious. "Although I have always had speculations, I am almost certain now. All of this is some kind of very special illusion, right?"
The old man was angry and shouted: "Nonsense! What an illusion, this is real! What, boy, do you think you can't accept reality anymore? It's unacceptable that you worked hard to the end, but you have an extremely miserable ending? But? This is reality, this is the reality brought about by your curiosity!
Do you think this is an illusion? Then tell me, where is the lie? Look at everything around you and feel your body. Do you think anything is unreal? "
"But I'm still skeptical." Richard said with a slight smile.
The old man snorted: "But no matter how you doubt it, this is the real world!"
"Then -" Richard said, looked at the old man, pointed to the side, and said, "Can you stand in that position and talk to me?"
"Huh?" The old man frowned, "Why?"
"Because I found that you haven't moved at all since you appeared. This is a bit strange..."
Before Richard finished speaking, the old man walked to the place pointed by Richard, stood in front of the wall at the end of the library, and said disdainfully to Richard: "Why, you think that if I haven't moved around, it's just an illusion." , do you think I am some unreal projection
Oh, pathetic boy, accept it all. Your body is already damaged, toxins are spreading throughout your body, and you don't have much life left. If you don't ask for my forgiveness, you will die. "
"What you said seems to make sense." Richard nodded "deeply", 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. Those who were hit at that time did not feel any mana fluctuations. Although every detail of it was imitated without any problems, and no flaws could be seen with the naked eye, but... if it is fake, it is fake."
"Impossible!" the old man shouted, as if he was a little out of his mind. "Is there anything wrong with this world, this real world? If your eyes can't find anything wrong, why do you say it is false? Is there anything wrong with it?" , just based on your imagination?!"
"Of course not." Richard shook his head slowly, "I have to admit that your methods are very sophisticated, making it difficult for me to find flaws with my naked eyes. But the problem is... I not only have eyes, but also other sensors, such as ears.
You did imitate the current illusion very real, but you are unable to imitate it, or you are not aware of the physical rules. Therefore, in my perception, the current world and library lack something that should exist. "
"What?" The old man couldn't help asking.
"Echo!" Richard gave the answer.
"Echo?" The old man was stunned and confused.
"Yes, echo." Richard explained calmly, "When sound waves are projected onto a large-area obstacle that is some distance away from the sound source, part of it will be absorbed, while the other part will be reflected. If a person hears the sound coming from If there is a clear time interval between the sound directly from the source and the sound reflected back, the difference between the two sounds can be distinguished, that is, an echo is generated.
Generally speaking, the shortest time for humans to distinguish echoes is 0.1 seconds, and the speed of sound propagation in air at 15 degrees Celsius is 340m/s.
It is now November, which is the cold month, and the temperature inside is relatively low at night, but in this library, the temperature is acceptable, about 15 degrees Celsius. The library is approximately 12.5 meters wide and 22 meters long. Where you are standing now is more than 17 meters away from the farthest wall, which is about 20 meters.
The time it takes for the sound to come out of your mouth and reach my ears is basically negligible. But it takes about 0.12 seconds to get to the farthest wall and then back to the farthest wall, which is enough for me to hear the echo.
However, I heard no echo. Whether it's asking you to change positions or stimulating you to speak louder, echo is completely non-existent.
Obviously, this is an illusion, a very special but indeed fictitious illusion. All things and insects are made by you, and so are sounds, so there is no echo. "
The old man's expression changed little by little as he listened to Richard's words. Although he couldn't quite understand what Richard was saying, he was sure that Richard had really seen through his methods, and his eyes were cloudy and uncertain.
At this time, Richard looked at the old man and said: "Since it is an illusion, it is much easier to handle. 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 It’s not really easy to control, especially after I realized this is a fake world.”
"So -" Richard said, reaching out and slowly grabbing the rotting skin on his body, digging his fingers deeply into it, and then pulled hard.
"Stab it!"
The skin was torn off like a coat, and you saw that there was no bloody flesh under the skin, but brand new clothes.
Then Richard bent down, picked up the chopped off calf, and connected it to the incision. With a "click" sound, the two came together like a magnetic attraction and returned to their original state.
Richard nodded with satisfaction, stood up straight and looked directly at the old man.
The old man's expression changed completely. Looking at Richard who was completely back to normal, he had a premonition of losing control. A trace of panic flashed in his eyes, his lips pursed, and he subconsciously stepped back.
