Hong Daoshi was influenced by his father Hong Lao Dao since he was a child. Hong Lao Dao is a Taoist master with excellent professional quality, with unique insights and research on yin and yang, five elements, and eight trigrams, and can also integrate the ideas of Buddhism and Taoism. Usually for the funeral of others, for the deceased excess, both the Taoist rituals, and the use of Buddhist scriptures, can be said to eat both, the essence of Buddhism and Taoism for their own profession, and meticulous work, the deceased often dream to the family, said that under the excesses of Hong Lao Tao has been buried for peace or reincarnation. Hong Lao Dao was very relieved to receive the gratitude of the family of the deceased, he knew that there were people outside the world, and there was heaven outside the sky, so he always worked hard to improve his Taoism.

The biggest problem that Hong Laodao encountered was that he had not yet opened the Heavenly Eye, that is, he could not see or experience some things in the underworld through the naked eye. The underworld is actually the fourth dimensional space, and the ghosts who live in it can see people, but people can't see ghosts, because the fourth dimensional space is curled up to the size of Planck. Master Hong didn't know what the fourth dimensional space was, he only called it the supernatural space, or "the underworld". Although Hong Laodao has summed up a lot of experience in the funeral activities, and has some innovative thinking to improve Taoism, he still does not have some conditions, mainly because he has not yet opened the eye of the sky, just like medical scientists and biologists, without the tool of the microscope, how can he carry out the next step of research and research?

Hong Laodao not only did not open the eye of heaven, but almost blinded his own eyes. Why? Because Hong Laodao has always worked conscientiously and responsibly, he is meticulous about funerals, just like Confucius in the "Analects" is very cautious and serious about sacrifices and funerals, and he is never sloppy. Once, Hong Laodao personally surveyed for 7 days and showed a poor man a cemetery, in his opinion, this is a treasure land with excellent feng shui, after this poor man is buried, his descendants will be born, at least become provincial and ministerial cadres. Hong Laodao was excited about his discovery, and at the same time he was very conflicted. Because it is not easy to discover such a feng shui treasure, just like the geological exploration team discovered a gold mine, how can you give up easily if you find it? If you don't give it up, give this piece of feng shui treasure to this poor man, and his descendants will be developed, isn't this a wedding dress for others? Moreover, if he found a treasure land, if it leaks out, his eyes will be blind. Hong Laodao was conflicted. However, after all, the secret of heaven cannot be revealed, and Hong Laodao finally did not reveal this feng shui treasure land, and showed the family an ordinary cemetery. In fact, the feng shui cemetery is not nonsense, it involves courses in hydrogeology, underground fluid seepage mechanics, etc. Hong Laodao himself does not know these disciplines, and he has his own rich practical experience. He recorded this feng shui treasure in his writings. Because of this huge discovery, although it did not offend the heavens by revealing the mechanism, but after all, it was the discovery of the "secret of God", Hong Laodao suffered from an eye disease, and his eyes shed tears every day, as if he had entered the sand. His family grabbed more than a dozen pairs of Chinese medicine for him, but it didn't work. Seven or forty-nine days later, Hong Laodao's eyes miraculously improved. Only he understood the reason, and he never mentioned this treasure again. This eye disease dealt a heavy blow to Hong Laodao, which brought a very bad impact on his technical research in opening the Sky Eye.

One day, when the scorching sun was in the sky, Hong Laodao dried millet for the production team. After two hours of labor under the scorching sun, he took refuge in a dark hut to rest. The house was usually dark and damp, and it used to be a small temple dedicated to the Bodhisattva of the land, but then it was broken down and abandoned. The moment Hong Laodao entered from the scorching sun, he felt that his eyes were full of stars, and he couldn't see anything in the hut, but he just felt colorful spots of light floating around in front of him, he knew that this was because he had been exposed to the scorching sun for a long time, and he didn't care. But before he knew it, he saw two men in black and white clothes appear in the dark room, and the one in white had a long tongue. Hong Laodao trembled, he knew that this was the legendary black and white impermanence. Hong Laodao clearly heard Hei Wuchang say: "Go faster, if it's too late, you won't be able to complete the task, and then the Lord of Hades will blame us, and we won't be able to bear the board." Hong Laodao softened, although he usually did some rituals, but it was only an indirect connection with ghosts and gods, and he didn't see ghosts and gods directly like today. He knew that he had opened the eye of the sky. Ordinary people who go to a shady place after being exposed to the sun will not see anything that is already invisible. However, Hong Lao Dao usually has a certain degree of Taoist cultivation, so in this state of stress, he sees some things in the fourth dimensional space. Yes, the two Qincha, black and white impermanence, as well as the king of Hades, live in the fourth dimensional supernatural space, which is an objective real existence. Hong Laodao hurried back to the village, and as soon as he entered the village, he heard that an old man in the village had just died. The funeral was still presided over by Hong Laodao, and he knew that the black and white ghosts he saw in the hut were real, and his eyes opened inadvertently.

Later, Hong Laodao found that his Tianyan was not opened often, and could only be opened by chance in a state of stress. We all know that in Jin Yong's novel "Dragon Babu", Duan Yu's six-vein divine sword can only be used in an accidental state of stress, and it cannot be easily exerted in ordinary times. The same is true of Hong Laodao's Tianyan. He knew that his level in this area could not be improved. Because his Heavenly Eye was opened too late, he was too old, and his Heavenly Eye had already closed, and it was only because of his own diligent study and hard practice that he had gained the foundation of Taoism that helped him open part of the Heavenly Eye.

Unexpectedly, Hong Daodao's son, Hong Daoshi, completely opened the eye of heaven by himself when he was young. Once, during the Chinese New Year, Hong Daoshi followed his mother to kill chickens by the pond. When the mother was cleaning up the chicken feathers after killing the chickens, Hong Daoshi was playing with kitchen knives. Accidentally, the kitchen knife fell into the pool. Hong's mother was anxious, slapped Hong Daoshi hard and scolded him for being a loser. At that time, the kitchen knife at home was the means of production at home, and it was as important as the ploughing cattle in ancient times. Remembering that there was a big magnet at home, Master Hong tied a rope with a bamboo pole and tied the magnet, and finally fished the kitchen knife out of the pool. Hong Daoshi looked at this magnet and felt very excited, and at night when he went to sleep, he put the magnet in the bed, guarding the magnet like his own child. He stroked it gently with his hand, staring at it in the darkness with his dark eyes. Gradually, Hong Daoshi found that the magnet emitted a strange brilliance, and the traces came out from the edge of the magnet, which was very beautiful, and he didn't know that this was actually the magnetic inductance line emitted by the magnet. Master Hong rubbed his eyes and continued to observe, the magnet still glowing faintly. From then on, every night, Master Hong slept with the magnet and communicated and talked with it with his heart.

Physics textbooks tell us that magnetic inductance lines are some curves that depict the distribution of a magnetic field. The tangent direction of any point on the curve is the same as the direction of the magnetic field at that point. The magnetic inductance lines are closed curves, and scientists specify that the direction of the north pole of the small magnetic needle is the direction of the magnetic inductance lines. The magnetic inductance lines around the magnet all come out from the N pole and enter the S pole, and the magnetic inductance lines inside the magnet go from the S pole to the N pole. Put a bar magnet and some iron filings on the flat glass, and the iron filings can be attracted by the magnet to show the magnetic inductance lines. After all, the magnetic inductance line is just the curve of people's illusion, but Hong Daoshi saw it with the naked eye.

A month passed, and Hong Daoshi's uncle came to his house on business. Master Hong said to his uncle, "Why did you bring a little child to my house? Who is she? ”

Hong Daoshi's uncle was surprised: "I came alone, how can there be two people?" ”

Hong Daoshi said: "It's just two people, look at how beautiful this little sister is wearing this red dress!" Hong Daoshi's mother didn't see the child either, and told him not to talk nonsense.

Uncle Hong suddenly understood something, and he quietly pulled Hong Daoshi aside and asked him to tell him what this little girl looked like. Daoist Hong carefully said what he saw, and Uncle Hong's heart was shocked, this was obviously his long-dead daughter Jin Lan! That year, before Hong Daoshi was born, Uncle Hong came to his sister's (Hong Daoshi's mother) house as a guest, but he left Jin Lan at home, saying that he would bring her delicious food back from his aunt's house. In the afternoon, Uncle Hong took the oranges back, but he didn't see Jin Lan, but later found Jin Lan in the ditch, and Jin Lan drowned in the ditch. A few years have passed, and Uncle Hong is still sad about this incident, but today he heard Hong Daoshi say that the little girl he saw was exactly the same as the day Jin Lan drowned! Uncle Hong believed that Hong Daoist really saw it, and later Hong Laodao found that Hong Daoist could still see many things that ordinary people couldn't see. He knew that Hong Daoshi's Heavenly Eye had opened unconsciously. In fact, Hong Daoshi opened the eye of heaven because of the magnet in his bed. The electromagnetic waves emitted by this magnet were induced by the Yin and Yang Qi that was born with the Hongdao Master, so that the Hongdao Master's naked eye expanded the visual range of the electromagnetic waves, so that he could see things that ordinary people could not see. Ordinary people, even if they are accompanied by a magnet all the year round, may not be induced by it, which requires the proper cooperation of yin and yang, five elements, and eight characters to achieve a resonance state, so as to break the barrier of the Planck scale with the help of the electromagnetic waves of the magnet, so that things in the fourth dimensional space can be observed.

Hong Lao Dao was overjoyed when he found that his son Hong Daoshi had opened the eye of heaven, and felt that his skills had someone to pass on and would not be buried, so he decided to let Hong Daoshi follow him to learn and practice. At that time, reading was not very attractive, people wanted to learn a trade, and there were many stonemasons and carpenters among his peers. When he was twelve years old, he began to learn art from his father. One of the reasons why he chose to learn Taoism from his father was that he would have meat to eat. In those days, it was not easy to have food to eat, and if you could get meat to eat, it would be even more unattainable. Ordinary people, it is a great joy to be able to eat a meal of meat in half a year. Hong Daoshi followed his father to learn art, and once he encountered funeral matters, he would get meat to eat, which was a very remarkable thing. Today, some readers are tired of eating big fish and meat, and they have disdained meat. But don't forget, what you eat now may be clenbuterol, poisonous food, how can it compare to the real natural food at that time?

After Hong Daoshi followed his father to learn art and become a Taoist, the main thing was to run and run tricks, and he couldn't get into battle. This is also a learning process, after years of experience, the level of Hong Daoist has been more and more recognized by his peers, and finally he has become a well-known Taoist master. This time, Hu Kehao and the three of them were able to escape from the maze of the Seventy-Seven and Forty-Nine Palaces because of the help of the Heavenly Eye that Hu Daoshi had opened when he was a child.
