In Hua Taizong, the waist card is the pass, and Han Shengwei came to the Hall of Experience.

The hall of experience is a place to store the cultivation experience of the cultivators of the past dynasties of this sect, which is equivalent to the Tibetan Scripture Pavilion, and the architectural style is naturally not ordinary.

Another important function of the Hall of Gain is to record the history of Huatai Sect, which is responsible for the control of the history of the specialty, and the history books are usually placed at the entrance of the Hall of Experience, and anyone who is qualified to enter the Hall of Gain can read it.

If there is an event worthy of recording, the control in charge of revising the history will be directly written in the history of the sect, and the contents of the record will be written in the same place. The materials used in the annals of history are very special, like paper and not like paper, which is extraordinarily durable.

The first series of books that Han Shengwei saw in the Hall of Experience was the history of Huatai Sect, a sect of more than 10,000 years, and there are hundreds of books on the history of the sect, and the cover of each volume is marked with the year of the record.

On the cover of the latest volume, there is only a record of the starting year, which is the first year of Huatai.

Han Shengwei picked up the latest history book and turned to the first page, and found that the text recorded on it only occupied one-third of the area of the page, and only three pieces of information were recorded.

The first item: God is now changing the yuan, and the year of the sect is August of the first year of Huatai.

The second item: In August of the first year, there are exercises handed down.

The third item: In September of the first year, the five sects sent Shi He, and all the sects also came, and all the countries congratulated.

The first item is that there is a real immortal who appeared in Hua Taizong, and Hua Taizong commemorated this event by changing the era name, and decided to replace the original era name with the name of Hua Taizong, because the month cannot be changed, so the start time of the new era name is August of the first year of Hua Taizong.

The second item is that in August of the first year of Huatai, there was a real cultivation exercise in Huataizong, and under the instruction of the sect master, the exercise has been distributed to the elders of all departments.

The third item is that in September of the first year of Huatai, the news of the appearance of immortals in Huataizong has spread throughout the entire Xiuzhen Continent, and the other five major sects have sent envoys to congratulate, as well as all other small and medium-sized Xiuzhen sects have also come to congratulate. Not only the Xiuzhen Sect, but even the ordinary countries in the entire Xiuzhen Continent also sent special envoys to congratulate them.

Looking at these three short records, Han Shengwei felt a little funny, which was exactly the same as the Chinese history books he had read on Earth before.

The Chinese culture is profound and extensive, coupled with a unique way of expression, and perhaps there is a reason why it was too troublesome to engrave words on bamboo slips in ancient times, so the ancients would cherish the words like gold, and those that can be explained simply will not be verbose.

And here, it is clear that the speeches are all in the vernacular, but the records in the annals of history are like ancient Chinese texts, if it weren't for Han Shengwei knowing what these three records said, he really couldn't understand the specific situation at first reading.

All three of these records only explain the events, there is no cause and effect, and they do not show exactly the connection between the events, such as why the gods appeared, what they said and did after they appeared, and what happened after that, etc.

If people read it thousands of years later, it is really not easy to understand, and it seems that the study of history is indeed not so simple.

With the experience of these three records first, there is no need to read the other historical records, and I don't understand after reading them, Han Shengwei put down the historical records and walked inside.

The Hall of Experience is really like a large library, with bookshelves divided into two layers, evenly distributed and neatly arranged.

Books placed on the upper floor are shoulder-height for easy searching, books placed on the lower floor are at the same level as your hand for easy access, and there is a two-meter distance between the shelves for easy walking.

All the books in the hall of experience are not borrowed, nor are they allowed to be copied and taken out, and the students can only read in the hall, and there are few people in this hall, and it seems that they have spent their energy on actual cultivation.

The book placed here has a brief introduction on the cover of the booklet, outlining the lifespan and cultivation direction of the person who left the experience, so that the learner can choose to read it.

The first time Han Shengwei came here, he didn't have any set goals, he just walked casually, and after flipping through a few books, he understood the division of this heaven and earth in the cultivation realm.

Different from the cultivation realm of Taoism that he knew, the cultivation realm is distinguished by the life span of the cultivator, and the only criterion for achieving success in cultivation is flying in the sky, Han Shengwei doesn't know if this is the same thing as flying in the day, he is still a layman in this regard.

When he moved on to the ninth shelf, a book with the words 'All in Tension' caught his eye, and he was naturally reminded of Newton's law of universal gravitation.

The owner of this experience once lived to be 400 years old, according to his limited understanding of this heaven and earth, he knew that this person was already quite remarkable, and the ordinary people of this world were also limited to 100 years old, and the maximum lifespan of a cultivator was only 500 years old, and few people lived to 600 years.

The inspiration for this experience came from an accident. Once, when the man was meditating beside a waterfall, he woke up hungry, caught a fish in a pool, and then made a fire to roast the fish, and then he found that the water was always flowing lower and the fire was rising.

The man did not understand this natural phenomenon, so he asked himself: Is it the water in front that pulls the water behind, or does the water in the back push the water in front? Does the fire above lift the fire below, or does the fire below lift the fire above?

The first half of the book is an explanation of 'all have tension', and the second half is a specific application of this theory in cultivation.

The tension in this theory is the thrust, which is the exact opposite of the gravitational force in the law of gravitation, and can explain all the concepts involved in the law of gravitation, but it needs to be understood in reverse thinking.

The tension theory holds that the reason why water flows lower is because the external thrust of the water is greater than the thrust of the planet itself, so the water can only flow to the lower place, and the water behind pushes the water in front of it to go lower.

The reason why the fire rises is because the heat produced by the fire combustion is also energy, and the thrust generated by itself plus the thrust of the planet is greater than the external thrust, so it will rise, and the height of the rise is proportional to the positive thrust it bears.

This theory also explains why the atmosphere does not disperse. Because the gas is too light, it is pushed farther by the thrust emitted by the planet itself, but after a certain vertical distance, it is just right to balance with the external thrust, so the atmosphere will condense and not disperse.

The theory believes that the generation of meteors is also due to the thrust, because the thrust breaks the original equilibrium at a certain time, so the stars will break out of their original orbits under the action of thrust, and then shuttle between the universe indiscriminately, plus they are affected by the thrust of different stars when shuttling, and occasionally the phenomenon of acceleration will be formed.

The acceleration phenomenon when the object falls from a high place is also formed under the action of external thrust, and the dual force of the mass of the object and the external thrust is more and more greater than the thrust of the planet itself, and the acceleration phenomenon will appear, and it will gradually intensify.

This phenomenon does not exist on very small objects of mass, such as tiny feathers, dust, and spores.

However, there is no hypothesis about the formation of the universe in this theory, and it may be that the cultivators believe that the universe should have existed in the first place.

Han Shengwei associates the Big Bang theory of the singularity of the universe, and after combining it with the theory of 'all with tension', he finds that this theory seems more reasonable than the law of gravitation, because the universe is constantly expanding outward, and how can it expand without infinite tension?

However, Han Shengwei prefers to accept the law of gravity because he is from the earth.

The second half of this experience is based on the theory of 'all have tension', which holds that the energy necessary for a cultivator's cultivation is innately present, and the reason why it is sensed by the cultivator is that the energy is pushed to all corners of the universe by its origin.

The cultivator senses the energy, establishes a connection with it with his thoughts, uses the energy to gradually improve and change himself, creates an inner space at the dantian to store energy, and tries to compress the stored energy to form a tiny enchantment in the body.

Then resist until completely eliminate the thrust of the planet's own divergence, let the energy under the action of the thrust of its own birthplace, accelerate the speed and total amount of energy entering the tiny enchantment in the body, and then compress it, and so on, so that the energy finally forms a qualitative change.

However, this method does not mention how the cultivator should use the energy after it has been stored, so as to achieve freedom in sending and receiving, or how to make the energy aggressive.

In Han Shengwei's view, these cultivation experiences are similar to the cultivation methods of Taoism on earth.

Isn't it the practice of qi to induce energy and establish a connection with it; isn't it to build a foundation by changing oneself and creating an inner space at the dantian that can store energy; isn't it to compress the stored energy so that the energy forms a tiny enchantment in the body; and the subsequent method until the energy reaches a qualitative change is not the completion of the golden pill?

Han Shengwei felt a little strange, these were two different universes, how could they be so similar in terms of cultivation, maybe this book of experiences was just an example, but why was the name and function of the word dantian exactly the same?

It can't be said that these are all speculative imaginations, but the people who left their experiences lived to be 400 years old.

The stage of Qi training that Taoist Xiuzhen talks about and the Qigong that Huaxia Kung Fu advocates are also the same thing, not to mention the medicine king who is already over 160 years old, Han Shengwei himself has already opened up the second pulse of Ren Du, and he does not dare to say that the qi of Qigong is released, and the fact that he strengthens his body is also beyond doubt.

Han Shengwei originally wanted to continue to look at other experiences, in an attempt to confirm the similarity of the two different universes in terms of cultivation.

But at this time he was hungry, and before he knew it, he stayed in the hall of experience for most of the day, and besides, some things were not in a hurry, and gradual progress was the best way.
