The sound of hurried footsteps was particularly loud in the empty and unmanned campus, and the hazy moonlight stretched the figure of the passer-by for a long time.

Zheng Gang subconsciously aimed at the moon in the sky, there were obviously no clouds in the sky, but the moonlight was not bright but revealed a haze. The older generation of people call this celestial phenomenon the Mao Moon, Zheng Gang vaguely remembers that when his mother told him a story when he was a child, he said that the Mao Moon is the easiest to hit evil spirits.

A faint uneasiness welled up in Zheng Gang's heart, the road out of the school seemed to be particularly long, and several people walked for more than half an hour, but they still didn't see the shadow of the school gate mentioned on the map.

"Why haven't you arrived yet, look at the signs on the map, the school gate should have arrived a long time ago! Fang Mu, are you taking the wrong direction? ”

Zheng Gang's physical energy was consumed to the limit, and his hurried pace slowly slowed down. seems to be complaining, but in fact, he is venting his inner anxiety and talking to Fang Mu.

Fang Mu ignored Zheng Gang's accosting, and he stopped. As a criminal psychology planner, Fang Mu's observation of details is definitely much stronger than Zheng Gang's. He'd already noticed something was wrong.

According to the speed of their pace and the time they walked, this distance should have been completely out of the school, but until now they still had not been able to see the shadow of the school gate, and even the scenery on both sides of the road had not changed.

They're always on the same page!

At this time, the captain of the soldier who was walking at the end of the line suddenly spoke, "The direction of the Fang Mu Belt is definitely not wrong, but have you noticed that we have been walking for more than half an hour, and the scenery on both sides of the road seems to have not changed much?" We should have encountered a ghost hitting the wall! ”

The words of the captain of the soldiers made everyone's hearts chuckle, and the unease and nervousness began to spread rapidly in the ranks.

"Ghost hitting the wall?"

"Hit the wall against the ghost! The so-called ghost hitting the wall is to suddenly get lost in a familiar place and can't get out. I only heard the older generation talk about it when they talked about it, saying that if they encounter a ghost hitting the wall, they will take off their underwear and put it on their head, and walk in one direction, and they can walk out of the ghost hitting the wall.

Or pull the zipper and pee on the dick. If it doesn't work, find a stone on the side of the road and throw it at the back, and at the same time say 'Taishan Stone dare to be here'! ”

The soldier said several ways to deal with the ghost hitting the wall, but none of them sounded very reliable. Zheng Gang nodded approvingly, and explained: "I've also heard of these, and panty pullovers can crack bad luck." And peeing is because the legend says that ghosts are also afraid of filthy things, otherwise how can there be black dog blood, and the legend that a woman's menstrual belt can drive away evil spirits!

As for throwing stones, shouting 'Taishan Shi Dare to Dang' is based on the legend of Shi Dang. Legend has it that there was a person named Shi Dangdang in ancient Taishan, who had high mana, and the demons and monsters were afraid of Shi Dangdang. The local people of Mount Tai because the stone dare to be there, so the days are very peaceful, and later the people from other places also came to ask for help, but the stone dare to be the doppelganger lacked skills, so he found a piece of Taishan stone, engraved on it 'Mount Tai stone dare to be' these five words, let people take home and stand on the wall at home, the demons and monsters will be afraid to flee after seeing it, so when the ghost hits the wall and throws stones, shouting these five words will have the effect of exorcising evil spirits. ”

Hearing Zheng Gang's explanation, everyone was also relieved, and immediately tried according to the method proposed by the captain of the soldiers, but found nothing.

However, although it did not help, the originally tense atmosphere was somewhat eased by these actions that can be called sand sculptures.

"These earthworks are useless, I have read some journal papers, and a biologist once did an experiment where you blindfolded a wild duck and threw it into the sky, and the duck would fly in the air, but the biologists found that the trajectory of the duck in the air was a regular circle.

Blindfold ordinary people and let them walk in a straight line according to their feelings, and the final trajectory is also a circle. So scientists put forward the conjecture that the essence of biological motion is actually a constant circular motion, and if there is no goal, the instinctive motion of any living thing is a circle.

Because there are subtle differences in the body structure of living things, such as the wings of birds, there are subtle differences in the strength and muscularity of the two wings. In the same way, there are also differences in the strength and length of people's two legs, so that the distance of the steps taken will be different, for example, the distance of the left leg is long, the distance of the right leg is short, the deviation is constantly increasing, and the final trajectory of action must be a big circle.

So why do living things keep moving in a straight line? Why can people walk in a straight line? It is because we use our eyes to constantly correct the direction, our brain is constantly positioning and correcting, and constantly correcting the deviations we cause, so a straight line is formed.

We're always going around in circles here now and it's not so much a ghost hitting the wall as a ghost covering your eyes! Different from the superstition of Zheng Gang and the captain of the soldiers, Fang Mu seems to want to interpret the ghost hitting the wall from a scientific point of view.

"Ghost Blinding?" The new term in Fang Mu's mouth made the people present a little confused.

"That's right, the ghost blinds, to put it bluntly, because of some kind of interference, our eyes and brain now lose the common function of correcting deviations, or the correction signals given are false and chaotic. We think we walk in a straight line, but in reality we walk according to our instincts. ”

"So do you have a way to find the right direction?"

"Of course, give me your dagger!"

Taking the dagger from the soldier captain's hand, Fang Mu took a deep breath and slashed at his palm.

The soldier captain's knife was very fast and sharp, and as soon as the blade touched the epidermis of the palm, red blood came out of the wound, and the stinging pain from the palm made Fang Mu's somewhat sluggish brain regain some clarity.

"Follow me, don't leave anyone behind!"

Everyone began to follow Fang Mu's method, holding hands and following behind Fang Mu one by one, and the surrounding scenery began to gradually become a little blurry and then changed. The tall trees on either side began to grow smaller and smaller until they disappeared, replaced by the abandoned women's restroom they had seen earlier.

For half an hour, several of them were actually circling around the abandoned women's toilet all the time! From the very beginning, when they came to the abandoned women's restroom, they fell into the ghost wall!

The soldier patted Fang Mu on the shoulder twice, and Fang Mu was obviously much more intimate than before, "It's useful!" I didn't expect Fang Mu's method to really work, your method is much more effective than the method on my panty pullover. ”

Fang Mu didn't think so, he was just about to say something but suddenly noticed that Zheng Gang's face had changed, and he had become a little frightened! What did Zheng Gang see?

Zheng Gang discovered a detail, a terrifying detail that no one present had discovered! There were 10 of them, but why were there only eight shadows on the ground? Of the ten of them, there were two people without a shadow!

Something slipped into them!
