Hu Kehao returned home, and his mother brought a steaming meal. Hu Kehao only ate a few biscuits in the car, his stomach growled with hunger, and the food brought by his mother was eaten in a few clicks. The father was smoking a cigarette next to him and slowly said to Hu Kehao: "Zhang Da from the neighboring village, he went to Guangdong to work after graduating from junior high school, and now he has become a contractor, driving a good car, and his children are two years old. That Zhao Erwa, your high school classmate, joined the job after studying vocational high school, and now he has become a small boss. Zhu Fatzi from Calamus Township, you are a few years older, you went to university and took the civil service examination, and now your annual income is at least 100,000 yuan...... Many of your peers have become parents, and dolls can play soy sauce. ”

"What are you talking about? Let the baby eat well. Mother said.

Hu Wenrui nagged there, worried about the child's future. Her mother didn't put pressure on Hu Kehao, she only cared about whether Hu Kehao was full and whether he was wronged at school. Hu Kehao knew what his father meant, he had grown up and should contribute to this poor family. It was not easy for his parents to study for him. They are all old now, and they hope that Hu Kehao can become the pillar of the family.

"At that time, I shouldn't have chosen theoretical physics, I should have applied for engineering majors, which would be better to find a job and earn more." Hu Wenrui said.

"Dad, I got the news a few days ago that I have been hired as a counselor by U City University of Technology, and I will officially start work at the beginning of school in September. I didn't tell you for the time being, but I wanted to surprise you. I have a salary, so you won't have to work so hard at home in the future. Hu Kehao said. When Hu Wenrui got the news, a smile appeared on his wrinkled face.

Taking advantage of this summer vacation, Hu Kehao wants to stay at home for a few days with peace of mind. Hu Kehao never figured out what happened strangely on the deadlock that night, which cannot be explained by the principles of physics. Hu Kehao clearly remembers that in physics class, the gray-haired old professor warned them not to be superstitious and to use the basic principles of physics to explain all phenomena in nature. All the secrets of nature can be explained, without supernatural magical powers.

After dawn the next day, Hu Kehao came to the deadlock he had walked through last night. He clearly saw the two cypress trees at the entrance of the stiff hill, surrounded by several luxuriant bargrass trees with rows of delicate thorns on the leaves. Clumps of fluffy dogtail grass grow around the barmao, swaying in the wind. The two large trees did indeed grow at the entrance to the Zombie Hill, and there were no other trees seen that night. Hu Kehao thought: magical supernatural phenomena may not occur during the day, the yang energy during the day is too heavy, the physical laws of nature are too strong, and supernatural forces cannot break the constraints of the laws of nature.

After dinner, Hu Kehao quietly came to the deadlock alone, he must find out what happened last night. He thought: If that happens again tonight, it will mean that beyond the three-dimensional space-time we inhabit, there is an unknown world that is not subject to the current laws of nature. If that night's events don't happen again, it can only mean that the eyes were overwhelmed that night, or that they were too tired and their minds were unconscious. Hu Kehao's purpose in doing this was only to maintain the sacrosanct scientific spirit in his mind.

From the beginning of the unitary time, Hu Kehao has been guarding the deadlock. He couldn't help but laugh at those cowardly "reversible ghosts", who only deceived the living, and when they saw the living people from other places, they came to make trouble, but they did not dare to show up to the people living in the local area. Hu Kehao's confidence in physics became even stronger, and everything on the deadlock could not escape the domination of the laws of optics and electromagnetism.

The evening breeze blew, and the surrounding leaves rattled. Hu Kehao heard soft footsteps in the distance. The voice was getting heavier and heavier, getting closer and closer to Hu Kehao. He was afraid of disturbing the sound, he didn't want to affect it, he was afraid that the sound would suddenly disappear, so he turned off the flashlight, he wanted to see what was coming in front of him. Hu Kehao studied quantum mechanics and knew that outside observation could have an irreversible effect on things themselves. For example, in an electron double-slit experiment, whether the experimenter observes which slit the electron passes through will affect the behavior of the electron. You're looking at electrons, and they're only going through a slit without interference; If the electrons are not observed, the electrons will interfere like waves through two slits at the same time. In other words, in the electron double-slit experiment, if you look at the electron, the electron is the particle, and if you don't observe the electron, the electron is the wave. Now, Hu Kehao was afraid of interfering with the sound in front of him, so he turned off the flashlight and hid himself.

Hu Kehao saw a faint firelight, and an old face appeared in the firelight. He recognized this as Uncle Cang in the village. Uncle Cang has no diploma, barely knows how to read, is not married, and is alone. I usually help the people in the village to do some odd jobs, fall in love with the temple and burn incense, and also help the people in the village send gods and invite ghosts. Hu Kehao had a serious illness when he was a child, and the injections and medicines did not work, and the masters in the temple said that it was a ghost, and later asked Uncle Cang to send the ghost, and the disease was cured.

Uncle Cang carried a bamboo rice sieve with a pair of wax skewers, a few pieces of straw paper, and a bowl of rice porridge. Hu Kehao knew that Uncle Cang was helping others send ghosts tonight. Uncle Cang came to a fork in the road, put the rice on the ground, lit the wax skewer with a lighter, stuck it in the ground, and burned the paper dots. This wax skewer is a thin bamboo stick, wrapped in cotton, the cotton is dipped in sesame oil, used during the sacrifice, just like the "wax" in the incense wax paper money in the temple now, Huaishu Village used to use cotton to wrap itself, and now it is basically to buy red wax made of ready-made wax oil to sacrifice. The wax skewers burned vigorously, but there were no three sticks of incense. I heard them say that incense is inserted only when praying and making wishes, and not when exorcising ghosts. After doing all this, Uncle Cang muttered a few more words in his mouth, which was nothing more than telling these ghosts to leave quickly after eating and receiving the paper money, and not to pester the patients in the village again. After speaking, Uncle Cang put the rice sieve on the ground again, and then turned back to go home. Hu Kehao knew that the person who sent the ghost at this time must not turn back, otherwise the ghost sent away would follow back. Hu Kehao didn't disturb Uncle Cang, once he looked back, he would have lost all his efforts tonight.

Hu Kehao was conflicted. If he laughed at and resisted such an ignorant behavior of Uncle Cang, he also asked Uncle Cang to send ghosts when he was a child, and he was cured of his illness after sending ghosts, what reason did he have not to thank and support Uncle Cang? If you support Uncle Cang, then where is the scientific spirit in his heart? How to face Newton and Einstein? However, it is said that Newton and Einstein also believed in ghosts and gods in their later years. What a contradiction.

Hu Kehao witnessed Uncle Cang walking home alone in the back. However, after a long time, Uncle Cang still circled in front of him, as if he was blocked by something. Hu Kehao bit his little finger, it hurt a lot, he knew that he was still in reality, and Uncle Cang obviously met a ghost who was in the wrong way. Hu Kehao wanted to shout loudly and wake up Uncle Cang, but he wanted to seize this rare opportunity to study this phenomenon well, and maybe he could write a paper for publication. He quietly approached Uncle Cang, while trying to stay awake as much as possible so as not to let himself fall into this illusion.

Be sure to keep first-hand information, Hu Kehao told himself. Fortunately, he was prepared, and he came with a bag of lime. He walked up to Uncle Cang gently, but Uncle Cang didn't even notice him. He sprinkled the lime on the ground, and Uncle Cang walked around, leaving a string of footprints on the lime. Hu Kehao looked carefully at the lines of these footprints, which seemed to reflect some kind of pattern. This image Hu Kehao seemed familiar, and he recalled it carefully. He thought of Professor Tan, who was the same age at U University, from Uncle Cang's age. Professor Tan has talked about potential well models in quantum mechanics. The potential well model refers to the fact that in many cases in the microscopic realm, the motion of particles such as electrons in metals, electrons in atoms, protons and neutrons in nuclei is confined to a small spatial range and is in a bound state. For particles in a bound state, it can be assumed that they are enclosed in a square box with an ideal reflective wall, and that they are not affected by other external forces in the box. The particles will not be able to pass through the walls of the box, but will only move freely inside the box. This is the potential well model in quantum mechanics.

Uncle Cang walked around in place, and when he came to a certain line, he folded back again, exactly the same as the motion of the particles in the potential well model. Walking around like this is not a way, Hu Kehao shouted loudly, and Uncle Cang seemed to wake up from a dream. Hu Kehao explained everything to him, Uncle Cang sighed, and they returned home together.

The next day, Hu Kehao, Uncle Cang and Li Tianbang came to the place where the lime was sprinkled last night. The footprints on the lime are still clearly visible. Hu Kehao took many photos of the footprints on the ground for future research and use. Combining his expertise, Hu Kehao can only think of potential well models in quantum mechanics. On closer inspection, the footprints seemed to have other meanings, but he couldn't see them. Uncle Cang usually burns incense to worship Buddha and does good deeds, but there is no special research in yin and yang feng shui, and he can't see what the footprints on the lime represent.

"I only invite Huang Jueya's Liu Banxian to come and take a look, he has been instructed by real people and is very good at this." Uncle Cang said.

"I don't believe in these evils, you guys have nothing to do." Li Tianbang said.

"You are a heavenly stick, you are not afraid of heaven and earth, why can't you go out of the zombie gang that night?" Uncle Cang said. Li Tianbang can't say, he did encounter a "ghost" that night, and he also wants to get to the bottom of it.

The next day, Uncle Cang rushed to Huang Jueya and invited Liu Banxian. Liu Banxian came to the scene to carefully investigate the footprints of Uncle Cang. I saw that there were words in his mouth, and he deduced it with the technique of five elements of gossip. Finally, he threw a hexagram on the ground, and saw that the hexagram pointed to Xunwei, that is, the southeast direction, and the hexagram was thirty centimeters away from the footprints. According to the principle of similarity, Liu Banxian pointed out that thirty kilometers to the southeast, there must be strange things. In view of the limited level, Liu Banxian couldn't figure out what the specific thing was, and someone needed to inquire in person.

Li Tianbang said: "I am full of food now, and the whole family is not hungry. Haozi is on summer vacation now, and there is nothing to do for the time being, so come with me! "This Li Tianbang turned out to be married and married a Yunnan wife, because he was a child, did not do his job, drank and gambled, and his wife ran away with others. I usually like to join in the fun, and when I encounter other people's family problems, I also love to help.

Hu Kehao has nothing to do at home anyway, so it is better to go out with Li Tianbang for a run, find out the strange things he has encountered in the past few days, and agree with Li Tianbang's opinion.

Thirty kilometers away is Calamus Township, which is even more remote than Baishi Township, where Hu Kehao and the others are located. The two of them called a motorcycle and spent thirty yuan to go to the Calamus Township Market. There are three streets in Calamus Township, and today is the day of the market, and there are many people on the streets. There are all kinds of vendors selling clothes, vegetables and meat, repairing shoes and repairing pots, and selling children's medicines. Hu Kehao and Li Tianbang rushed to the stomach hungry, they entered a small restaurant, and ate a big bowl of beef noodles by themselves.

Liu Banxian told them that something strange was thirty kilometers to the southeast, and they ate noodles and wandered around the street for a long time, but they didn't find anything. Hu Kehao said: "Thirty kilometers may be just an approximation, the actual distance may be 28 kilometers, or it may be 32 kilometers, let's continue to look for it." ”

Hu Kehao and Li Tianbang continued to walk in a southeasterly direction. After a while, I walked out of the block and came to a sheep's intestine path, which pointed to the southeast. They walked along the path for about two kilometers and found that there was a family holding a dam banquet in front of them, and the guests were full.

"It's definitely here, let's go check it out." Li Tianbang said.

"How can we go to a banquet at home? It will be embarrassing in case we are kicked out. We should send a red envelope. Hu Kehao said.

"Don't be afraid, just fish in troubled waters, and give red envelopes to expose yourself." Li Tianbang said. This reminded Hu Kehao of Li Yunlong, who ate the Japanese banquet in "Bright Sword", and they just took this opportunity to have a meal.

They spotted a table on which only six people were seated, including four women and two children. There are few of them, they don't eat much, and the dishes on the table are still very rich. They sat down while people weren't looking. One of the women asked, "You have only come now, and you have been at the table for a long time." ”

"We have something at home, and we're late." Li Tianbang said.

"I haven't seen you before? Where are you from? Another woman asked.

"We are from their cousin's second aunt's family." Li Tianbang replied. In recent years, relatives in rural areas have not moved around much, and their relationships have gradually become estranged, and many of them do not even know their close relatives, let alone distant relatives? They didn't ask anymore, Hu Kehao and Li Tianbang had already been grumbling with hunger, and they were bored to eat.

After eating a lot of meat and vegetables and drinking a few large bowls of wine, Hu Kehao and Li Tianbang were very full and satisfied. They learned that today was a wedding banquet, and the groom's surname was Zhou, and they learned that the daughter-in-law of the family was bought from other places. The bride was locked in the house, saying that she was afraid that the bride would make a big fuss and that the bride would run away.

Hu Kehao couldn't help but be shocked. This reminded him of the movies "Blind Mountain" and "Rose Life and Death Love", could it be that the bride of this family was also abducted? The guests looked very numb, no one cared about the bride's whereabouts, they just ate and drank, and the gift money they gave had to be eaten back, and they couldn't lose money.
