Hu Kehao and Li Tianbang rescued He Xin, and the three of them walked together. When they came to Maojiagou, Hu Kehao and Li Tianbang took motorcycles and passed through many forks in the road. Now when they went back, they couldn't remember the direction, and they walked by feeling, and before they knew it, they came to a small temple. There were still oil lamps lit in the small temple, emitting a dim light, and it seemed that there might be people inside.

The door of the temple was closed, Li Tianbang went to knock on the door, and an old voice came from inside: "Who?" ”

"We were night people and couldn't find a place to stay. Passing by here, please make it convenient for the master, we want to borrow your temple for a night. Li Tianbang replied.

After a while, with a squeak, an old man in his sixties opened the door and said, "Please come in, please come in!" You are lucky, today is the first day of the new year, incense is burned in the temple, and I will guard the temple here at night. The old man said that the men and women of the nearby villages would go to the temple to burn incense and worship the Buddha on the first and fifteenth days of each month. According to folk sayings, the first and fifteenth days of the lunar month are the time when the moon goes from waning to round, and from round to waning.

The old man invited them into the temple, pointed to a corner of the temple, and said, "The four of you will be in a moment, the temple is in a simple condition, only sleeping on the floor." ”

"Uncle, there are only three of us." Hu Kehao said.

"And a little kid? Where did he go? The old man asked.

"Uncle, don't scare me, we've always been three people!" He Xin said.

"Obviously there is a child following you, and he didn't come in at the door, so I'll go out and have a look." The old man walked out of the temple gate, and sure enough, he saw a child. The old man talked to him, and he did not answer. The old man stepped forward to pull him, he kept dodging, and the old man touched his body and found it empty. It turned out that this child was a wandering spirit, and He Xin met him at the grave, and he followed He Xin to the temple. The temple gate is guarded by the general of the door god, and the child's wandering spirit cannot enter. The old man kindly advised the child, saying that there is a difference between yin and yang, and that there should be no peestering the people in the yang world, so he grabbed a handful of paper money from the temple and sent the child's wandering spirit away.

Hu Kehao and the three of them were rumbling with hunger, and the old man took out some food, and they swept it away. After eating, the old man took out grain grass and mats to lay them on the floor. Hu Kehao saw that He Xin was very tired and injured, and Li Tianbang was a lazy man, so he took matters into his own hands and quickly laid the ground, and the three of them lay down in clothes.

Although the oil lights in the temple are dim, you can clearly see the kind face of the Buddha and Bodhisattva. This temple is dedicated to the gods of Taoism and Buddhism, such as the Jade Emperor, the Buddha of the Western Heavens, the Bodhisattva Guanyin, the ancestor of Hongjun, the god of the King of Medicine, and so on. In the eyes of the villagers, they don't know which are the Taoist gods and which are the Buddhist bodhisattvas, and they don't need to know. They only know some simple truths: no matter which way of immortals, even Christianity and Islam, there is a principle and purpose, not to do bad things, and a religion that causes people to do bad things is not a good religion. Religion does not call people to kill people and set fires, nor does it support corruption, otherwise it is a cult. The three of them bothered the gods late at night, felt embarrassed, and kowtowed to the Buddha and Bodhisattva reverently, and then rested. With the awe-inspiring righteousness of the Buddha and the Bodhisattva, they are not worried about the attack of ghosts, so they can sleep steadily.

Although it is a hot summer, the small temple is located in the wild, and the cool breeze blows, which is also comfortable. In the middle of the night, Hu Kehao was awakened by a sound, and a white light shot in from outside the temple gate. Hu Kehao was not alarmed, maybe this was a bodhisattva manifestation. It is said in ancient books that the manifestation of gods and bodhisattvas is to emit a cloud of white light, and only the manifestation of evil demons emits black light.

Hu Kehao stared at the white light, surprised that he was about to see the Bodhisattva appear. Unexpectedly, a cloud of black gas suddenly appeared in the white light, and Hu Kehao felt bad, thinking that the demon was coming. Sure enough, the black qi grew bigger and bigger, and finally turned into an ugly monster in the shape of a pig, and ate all the offerings in front of the Bodhisattva. When the monster had eaten its fill, it showed the true form of a pig and rested there limply.

"I've eaten a few temple offerings, it's really a burden to eat this!" The monster said. It turned out that this was not a monster, but a god, and the white light that appeared proved his identity as a god, and the black gas in the white light was just the black clothes he wore when he appeared. In fact, we all know this monster, he is the Pure Altar Messenger Zhu Bajie. At the beginning, after Zhu Bajie succeeded in learning scriptures with Tang monks, the Buddha named him as the messenger of the pure altar and specially enjoyed the offerings in the world. Zhu Bajie is a virtual character in "Journey to the West", and the Pure Altar Messenger is also virtual, why did the Pure Altar Messenger Zhu Wuneng Bajie really appear in this small temple and was seen by Hu Kehao? Although matter determines consciousness, and consciousness is the subjective reflection of the material world in the human brain, an idea will become a fact if it is widely circulated and widely recognized by everyone. "Journey to the West" is widely circulated, and Zhu Bajie has become a messenger of the pure altar in the book, which is agreed by many readers and considered reasonable, so Zhu Bajie really became the messenger of the pure altar, which is said to be the blessing of faith.

The temple keeper's surname is Guo, and it is said that he used to be a rural private teacher, and the men and women who burned incense called him Teacher Guo. Teacher Guo has to guard the temple on the fifteenth day of the new year, and he has seen the messenger of the pure altar come to the pure altar before. He felt incredible, and pondered the mystery. One day, under a yellow cypress tree, he finally realized the truth, which he thought should be explained as follows.

The problem of ghosts and supernatural beings exists objectively, and the scientific explanation for the phenomenon of ghosts and supernatural phenomena is time and space.

The problem of time and space is the most complex problem in the world. Throughout the ages, the years have passed, and this is time. This large container that holds all things in the universe, the sun, the moon and the stars is space.

There is a thin line and a leaf on the ground, and an ant climbs on top of the thin line, and if it only climbs on this thin line, he will not be able to climb on the ground, because the ant lives in the one-dimensional world, and he cannot reach the leaf in the second-dimensional world anyway. Above this thin line, the space of the second dimension is curled, and the ants cannot see the world of the second dimension.

There are two basketballs on the ground, and an ant crawls on the surface of the basketball, and the surface of this basketball is a two-dimensional world, and the ant only lives on this two-dimensional sphere, and he can't go to the surface of another basketball, and of course it can't go to another sphere with a different radius from the world it lives in now. On this two-dimensional sphere, the third-dimensional space is curled, and the ants cannot see the third-dimensional space.

In the same way, we live in a three-dimensional world, why can't we see the space of the fourth dimension? Einstein's theory points to four dimensions of space-time, but the fourth dimension is time, which is not space yet. The space we see and feel is only three-dimensional at most. Where exactly is the fourth dimension? Quantum mechanics and cosmology tell us that the fourth dimension is curled up to the size of Planck's size (i.e., 10 to the 33rd power of centimeters), so we can't see it and can't imagine it.

When a thing has length, we say that it has a one-dimensional space; It has length and width, and we say that it has two-dimensional space; It has length, width and height, so we say it has three dimensions. The projection of two-dimensional space on paper is one-dimensional, and the planar projection produces a line; The projection of three-dimensional space on paper is two-dimensional, and the projection of a space object produces a plane. Obviously, we know that the projection of four-dimensional space is a three-dimensional object. It is normal for ordinary people to not be able to see the fourth dimension, just like the ant crawling on the thin line, it cannot see the world beyond the thin line. The reason why human beings living in three-dimensional space cannot see the fourth dimensional space is because the nature of the fourth dimensional space is different from the known three-dimensional space.

In fact, our ancients have discovered the fourth dimensional space, as the saying goes, "one day in the sky, one year in the mortal world", and the fourth dimensional space is the world of ghosts and spirits that we are familiar with. Ordinary people don't have their eyes open, and they never believe in the fourth-dimensional ghosts and supernatural worlds. The world is usually curly, and the size of the curl is on the Planck scale, that is, 10 to the 33rd power. If the space of this scale is not affected by special forces, it will not open, and ordinary people will not be able to enter. But in the world, strange people are everywhere, and these people do not necessarily know the Planck-scale space in quantum mechanics, but they already know the key to open the door to this space. Although scientists know about Planck space, scientists have never believed in ghosts and supernatural worlds, so they cannot enter this world with scientific methods. Even if one day, the speed of the time-traveling machine reaches and exceeds the speed of light, even if time can be turned back, it can only enter another dimension, and this space is only three-dimensional, not fourth-dimensional. The three-dimensional dimension of another space is not the same as the fourth dimension of this space. His time shuttle only entered a pluralistic parallel three-dimensional universe, and did not enter the fourth dimension of this universe.

What is a multi-parallel universe? For example, someone A's girlfriend was hit by a car at 12 o'clock yesterday and died, and now someone A wants to take a time shuttle back to 12 o'clock yesterday to save his girlfriend. Sure enough, he had a time shuttle, and he really went back to the moment at twelve o'clock yesterday, and at that moment, he pushed his girlfriend away from the car with one palm, so her girlfriend was saved, and finally did not die under the wheels of the car. Someone A thinks that if he changes the past, he will change the future. Yes, now he saved his girlfriend, and if he had lived in the world of the "past", his girlfriend would indeed live well and not die. However, if he takes a time shuttle back to the present, that is, the current universe, his girlfriend will still be irretrievably hit by a car and killed. This is because the space he went back to is parallel to the current space, they are multiple parallel universes, and what happens in that space will not affect this space. The law of cause and effect does not change in each space.

We know that the space-time shuttle can only travel in parallel cosmic space, and these two parallel spaces are each three-dimensional, and the space-time shuttle does not let it enter the fourth dimension. However, there are some amazing people in this world, maybe he has not read a book, he does not understand the theory of relativity, he does not understand quantum mechanics, he does not know anything related to science. Because of this, their primordial thinking was not influenced and eroded by science, but found a way to enter the fourth dimensional space, that is, the ghostly and supernatural space. Those who have watched Jin Yong's "Chivalrous Journey" know that all the martial arts masters have profound skills and first-class martial arts foundations, but none of them have penetrated the martial arts on Xia Ke Island. However, Shi Potian couldn't read a word, and it was precisely he who understood the martial arts on Xia Ke Island. Because of this, scientists have tried every means not to enter the fourth dimensional space, and some people who have no scientific foundation, or who specialize in feudal superstition, can enter this space under certain conditions through their own practice.

This small temple is called the Stone Buddha Temple, and it is quite effective in the nearby villages. Why did the Altar Purifier appear this time? Because the traffickers in Maojiagou had good thoughts and released He Xin. The wicked can rein in the precipice, turn back to the shore, there are more and more good people in this land, the Bodhisattva in the stone Buddha temple is very happy, so he took advantage of the time of incense on the first day of the new year, invited all kinds of gods, as well as the messenger of the pure altar, under the worship of the good men and women, held a banquet. This pure altar messenger was fat, and when he came to enjoy the tribute, he was troublesome to change his body type, coupled with negligence, forgot to be invisible, and showed his true appearance, and was seen by Hu Kehao. The messenger's true form was seen by mortals and revealed the secret of heaven, this is not a joke, he has to find a way to fool the matter. The summer weather is changing, and a flash of lightning suddenly appeared outside the temple, and the white light shot directly into the temple. The envoy also saw that the mount of a clay sculpture Bodhisattva was similar to his own appearance, so he changed his body, and his true appearance gradually faded away, and he attached himself to the mount. This Hu Kehao looked at the lightning outside the temple, rubbed his eyes, and said to himself: "It seems that I am dazzled, this is an illusion caused by lightning outside the temple!" In other words, all the phenomena in this world can be explained by physical principles, how can a monster suddenly appear in the temple? ”

The breeze blows, and the stone Buddha temple is cool and pleasant. The four of them slept in the temple until dawn and were woken up by the sound of birds outside the temple. After the wind and rain last night, how many wildflowers fell outside the temple? Breathing in the fresh air, Hu Kehao and He Xin came to the outside of the temple and saw a mountain spring with flowing water. They wash their faces and rinse their mouths with spring water in their hands. He Xin washed off the stains on his face, and saw that his delicate skin was radiant. His hair flowed in the breeze and passed over Hu Kehao's face, and he felt the oxygen on his face.

Teacher Guo got up early, and when Hu Kehao and the others woke up, Teacher Guo had already cooked a pot of porridge, which was mixed with some rare herbs. Teacher Guo said that these herbs are collected on the slope outside the temple, pure natural food, absorbing the essence of the sun and the moon, eating can remove toxins in the body, replenish qi and circulation, relax muscles and invigorate blood, and prolong life. They ate two large bowls of pickles, feeling energetic and light.
