At this time, the old man made a noise, as if he was facing the judge of the sinner and said to Li Cha: "Boy, experience it, this is what you deserve for your arrogance, arrogance, no one in sight, and little cleverness! To get close to what you shouldn’t know, then it can only be-painful death!

　　I tell you, mortals should not have too much curiosity, curiosity will only hurt you! "

Speaking of which, the old man's tone suddenly changed again: "Of course, out of good intentions, I can give you a chance to change. You only have to make sure that you are no longer curious about what you should not be curious about. Things, live a good part. Then I can use some means to relieve your body from poisoning, and even give you a good leg. How?"

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

　　 "What do you want to say?" asked the old man.

　　Richard still didn't speak. He looked around and looked at his decaying body, looked at the calf that was cut off on the ground by himself, and finally looked at the old man again.

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

The old man was angry and shouted: "Nonsense! What illusion, this is real! Why, kid, do you think you can't accept reality anymore? Unacceptable, have you worked hard to the end, but have a miserable ending? But This is reality, this is the reality brought by your curiosity!

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

　　 "But I am still skeptical." Li Cha's expression smiled slightly.

　　The old man hummed: "But no matter how suspicious you are, this is the real world!"

　　 "That--" Richard said, looking at the old man and pointing to the side, 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 there hasn't been any movement at all, which is a bit strange..."

Before Richard finished speaking, the old man walked to the place where Richard pointed and stood in front of the wall at the end of the library. He said disdainfully to Richard: "Why, you think I haven't walked, it's an illusion. , Think I am some unreal projection?

　　Oh, sad boy, accept it all, your body is already crippled, toxins are spreading all over your body, leaving little life left. If you don’t ask for my forgiveness, there is only one way to go. "

"What you said seems very reasonable." Richard nodded "deeply" and then looked at the old man. "And the problem is, this is indeed an illusion. Although it is very special, I can't realize what I am. I didn’t feel any mana fluctuations when I was recruited in the time. Although there are no problems in imitating any details of it, there are no flaws visible to the naked eye, but... the fake is fake."

"Impossible!" the old man yelled, as if he was a little gaffe. "Is there anything wrong in this world, this real world? If your eyes can't find anything wrong, why is it false? , According to your assumption?!"

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

　　 You do mimic the current illusion, but you cannot imitate it, or do not realize the physical rules. Therefore, in my perception, the current world and library lack something that should exist. "

　　 "What?" asked the old man.

　　 "Echo!" Richard gave the answer.

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

"Yes, echo." Li Cha explained calmly, "When sound waves are projected on a large area of ​​obstacles at a distance from the sound source, part will be absorbed, while the other part will be reflected. If a person, hear the sound There is a clear time interval between the sound directly coming from the source and the sound coming back from the reflection, and the difference between the two sounds can be distinguished.

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

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

　　The sound comes from your mouth to my ears, and time is basically negligible. But to reach the furthest wall ~www.readwn.com~ and then there is a 40 meter path back, which takes about 0.12 seconds, which is enough for me to hear the echo.

　　 However, I did not hear an echo. Whether it is to change your position or to stimulate you to speak loudly, the echo is completely absent.

　　 It is obvious that this is an illusion, a very special but indeed fictional illusion. All things, insects, are made by you, so is the sound, so there will be no echo. "

　　 The old man listened to Li Cha's words and changed his expression a little bit. Although he didn't understand Li Cha's words, he could be sure that Li Cha really saw through his means and his eyes were uncertain.

Richard looked at the old man and said, "Since it is a illusion, it is much easier to handle. Although I don't know the specific principle of this illusion, it should be confusing my brain and producing the wrong electrical signal. And my brain can Not really easy to control, especially after I realized that this is a false world."

　　 "So-" Li Cha made a noise, reached out and slowly grasped the decaying skin on his body, snapped his fingers in deeply, and then yanked hard.

　　 "Stab!"

　　 The skin is like a coat. When it is ripped off, you can see that there is no **** flesh under the skin, but new clothes.

　　 Then Licha stooped down, picked up the lower leg, and aligned it with the cut. With a "click", the two were connected as if they were attracted by magnetic force and returned to their original state.

　　Richard nodded with satisfaction, stood up straight, and looked directly at the old man.

　　 The expression of the old man changed completely. Looking at Richard, who was completely back to normal, there was an uncontrollable hunch, a trace of consternation flashed in his eyes, his lips pursed, and he subconsciously stepped back. ...
