"Ghost hitting the wall?" As soon as he heard this, the timid fat man suddenly felt that the air around him had dropped by more than ten degrees, and he looked left and right for a while: "How is it possible, didn't you say that there are no ghosts?" ”

"Nonsense, the ghost hitting the wall is not really blocked by the ghost." Seeing that the fat man was hairy, Zhang Meng kicked the fat man fiercely: "I said, can you make a living, we have robbed so many tombs, why are we still so afraid of ghosts." ”

"Nima, you're light." The fat man's mouth pursed, and a pair of small eyes looked around: "Can that monster compare with a real ghost?" If it's a monster, there's a way to clean it up, but if it's a ghost, we big living people know a fart, if only Laizi was still alive. ”

"No, there is still Brother Jiu."

"Him?" The fat man glanced at Ye Jiu and said, "With his small body, how much blood can he squander." ”

"I don't talk nonsense with you, it's really hopeless." In the face of the fat man's actions, Zhang Meng no longer talked nonsense with the fat man, but turned back to look at Zhao San: "Third uncle, is it a ghost hitting the wall?" ”

"Like." Zhao San just responded with a simple word, and then shook his head: "But I'm not sure." ”

"What then?" The fat man asked.

"According to me, let's leave a mark on the wall now, and let's talk about it." After Zhao San finished speaking, everyone began to make unique marks on the way to go, and sure enough, after walking not many steps, Zhang Meng found the marks he left. At this moment, everyone was dumbfounded, and they all stared at the mark that had just been left on the wall, unable to say anything.

"Nima ghost hit the wall, ghost hit the wall" The fat man trembled and shouted: "It's really a fucking ghost hitting the wall, it's over, it's over, we can't get out now." ”

"Don't talk nonsense, I'll take a look." Zhao San said.

Seeing that the fat man was so nervous, Xiao Lou said, "Brother fat man, in fact, there is no need for you to be so scared at all. ”

"Nonsense, it's not that you don't know, what I'm most afraid of, fat man." The fat man cried with a sad face.

"You're afraid of ghosts." Xiao Lou smiled and said in the fat man's ear.

"I know you still say it."

"But this ghost hitting the wall is not a ghost, what are you afraid of?" Small staircase.

"Huh?" The fat man touched his head: "What do you mean, isn't this thing a fool?" But I remember that every time I came across this thing, Laizi used a charm to crack it, could it be that Laizi was also wrong? ”

"Laizi's talisman restrains the corpse qi, and it doesn't rely on any Taoism." Zhang Meng interjected and said: "Everyone knows that there are cinnabar and other things that suppress corpse qi in Laizi's charm, so they will be effective." You see Laizi using a spell to crack this ghost hitting the wall, but you don't know the real mystery of it. It seems that you haven't even touched the skin of Laizi. ”

"You know that?" The fat man said with a pout.

"If I knew, I would have been able to get out of this ghost wall by now." Zhang Meng sighed.

"Cut" The fat man rolled his eyes: "Then what are you proud of?" ”

Zhang Meng said to Xiao Lou: "Xiao Lou, it seems that I want to trouble you to popularize these scientific knowledge for the fat man." ”

"Huh." Xiao Lou smiled faintly: "Everyone knows that the so-called ghost hitting the wall is the phenomenon of going back and forth in a strange circle at night but not being able to get out." Many people have experienced it, but they don't know why, so they just say it's a trick. In fact, the principle is very simple, that is, there will be a slight difference in the length of our human feet, and then we will fall into a strange circle. To put it bluntly, it looks like it's walking in a straight line, but because of distance and vision, it's actually been walking in circles. ”

"Oh."

"It's like the geese in the sky, when they fly, they will always fly out of a circle unconsciously, just like us humans. In short, the essence of the motion of a qiē creature is circular motion. If there is no goal, the instinctive movement of any living being is a circle. ”

"Relying on the fat man, why don't I walk in circles?" The fat man said disdainfully.

"That's because we usually walk with plenty of light, and we have a target reference, and our eyes are constantly correcting the direction, that is, our brain is doing positioning and correction. Constantly correcting our gaps, so it goes in a straight line. And when the ghost hits the wall, you lose your sense of direction, which means that you are lost. Your eyes and brain are no longer corrective, or the correction signals you are giving are false or confused, and you feel like you're walking in a straight line, but you're actually walking in a circle. ”

"And the ghost hitting the wall we are encountering now must be artificially created." Xiao Lou guessed.

"But even though the light is dim, how did the guy who made the ghost hit the wall do it?" Qingzhi interjected.

"That's a good question." Xiao Lou nodded and said, "This is going to require something to confuse us, as long as we succeed in confusing us, everyone will feel that they still have a sense of direction, but in fact, they have already lost their way." ”

"So having said all that, is there any way to crack it?" The fat man asked.

"Just enough light."

"Nonsense, we're only left with this broken flashlight, where are we going to get the light?"

"That's the only way to crack it now." Xiaolou was a little embarrassed: "You can also go out to see the stars, but we are now in the submarine tomb, and we will definitely not see the stars." ”

"It's not impossible to find a light source." Just after the fat man and Xiaolou finished discussing, Zhao San on the side thought for a while and said, "I always feel that there is a smell here."

Zhang Meng hurriedly asked, "What taste?" ”

"Corpse oil."

"Corpse oil?" When Zhao San said this, Zhang Meng's nerves moved: "Third uncle, do you mean that there are wall lamps on both sides of this tomb?" ”
