"Hehe, this stupid girl, she doesn't care about her body so much!" Yuan Xi smiled helplessly, next time you must do some ideological work on Tutor Ya'er, only by keeping the most energy, the work efficiency will be higher, and continuous work will only destroy your body and reduce your work efficiency, working overtime seems to be completed, but the actual effect is not as good as the most prosperous state, you have to be tired yourself!

Yuan Xi can't let Ya'er sleep on her stomach like this, this sleeping position will also be bad for the spine, it is better to lie comfortably on the big bed!

Yuan Xi walked to Tutor Ya'er's side, passed one hand through the crook of her arm, and the other hand passed through the crook of her calf and knee, and lifted it slightly, and hugged this soft and boneless delicate body on her body, Shangguan Ya'er seemed to twist her body uncomfortably, Yuan Xi hurriedly used spiritual power to make a top on her slender waist, Ya'er's whole body began to balance out, and she adjusted a sleeping position very comfortably, just face to face with Yuan Xi.

Yuan Xi only felt a fragrance of her daughter coming to her nose in front of her, and Ya'er's stunning face was completely presented in front of her, her fair skin was snowy, her curved eyebrows, and long eyelashes were constantly trembling with her closed eyes, Yuan Xi was sure that she was not pretending to be asleep, but dreaming!

Only dreams will make the eyes move quickly, this is the biological theory that Yuan Xi talked about this month, and by the way, Xuanyuan Xi'er also gave her a physiological and hygiene lesson promised her, and the little goddess finally recovered from her ignorant state.

Yuan Xi hugged Ya'er's delicate body, her bare waist was as smooth as silk, Yuan Xi took a deep breath, "Let's let Tutor Ya'er sleep well, not sleep with her, based on this premise, superfluous movements can be avoided!"

Yuan Xi hugged Ya'er to the big bed next to the desk, gently put the soft and boneless delicate body away, and then covered the futon for her, Yuan Xi almost naturally slept on the big bed, Yuan Xi decided to move a big bed in, the small bed was just a joke, but in line with the inconvenience of Ya'er's tutor's boudoir, it was still put on the rooftop by Yuan Xi, and he could sleep there and look up at the starry sky when he was free.

Yuan Xi is really going to fall asleep, but he shook his head, this has not yet been approved by Tutor Ya'er, although Yuan Xi is usually not serious, but he still respects Tutor Ya'er very much, taking advantage of the danger of others or in the case of her unaware, Yuan Xi doesn't want Tutor Ya'er to wake up and open his eyes to see that there is an extra man beside him, even if he is a teenager, besides, our body has developed faster, and there are all physiological reactions that should be there, so it was embarrassing at that time!

Yuan Xi shook his head and smiled, and walked to the desk, which was full of notes and materials in front of him, the desk was very large, seven feet long and five feet wide, and there were still many vacant spaces for an adult man to sleep, but this bed-like desk was full of handwritten notes, all of which were Yuan Xi's painstaking works in the past month, from astronomy to geography, mathematics, physics, chemistry, biology, information engineering, and other basic introductions were all written!

This is all due to Ya'er's tutor Her endless questions aroused the memory in the depths of Yuan Xi's soul, this dream is very ethereal, you may not remember what you dreamed yesterday, but an impressive dream will make you not forget it for decades, and when Yuan Xi recalled it like this, he suddenly remembered that a great man said a sentence: "Study hard, make progress every day!"

Yuan Xi carefully sorted out the more than 10,000 notes in front of him, which had been divided into categories before, and now it was just based on Yuan Xi's first feeling that the depth of the content was typeset.

At that time, Tutor Ya'er looked at this pile of notes, Yuan Xi saw her smile like a little girl for the first time, she smiled so purely, so unabashedly, at that moment, there were no tutors and students, only two teenagers and girls who had endless exploration and discovery of everything in the world, for this universe, he and she were just a speck of dust, maybe emotional dust, but he and she really felt the silence and desolation of the endless world together!

In addition to the basic knowledge of mathematics, physics, chemistry, biology, information engineering, etc., the necessary topic of Yuan Xi every day is "astronomical cosmology"!

In the eyes of Mentor Ya'er, this belongs to the supreme morality and belongs to the category of Taoism, but she is also very interested, or rather, she is interested in whatever Yuan Xi says, and after discussing it every day, she began to look at the spirit bead record and copy down the notes, half of this dense note is Ya'er Xiujuan's font, and half is the font of Yuan Xi's dragon flying phoenix dance, which is easy to identify.

Among them, the most unbelievable aspect of the Tao is the origin and destruction of the universe, "Taoism really says that all things come from the Tao, and the Tao comes from chaos, chaos comes from being, and existence comes from nothing......"

At this time, Yuan Xi interrupted Ya'er's endorsement-like mode, "What is nothing?"

Ya'er pondered for a moment and replied: "Nothing is nothing, there is no space, there is no time, there is no air, sunlight, soil and water, there is not even extreme cold and extreme heat, there is nothing, there is nothing!"

Yuan Xi nodded and said: "The problem is here, since there is nothing, then why is it suddenly born? How is it born? From nothing, how did it come about?"

Yuan Xi asked a question that even the Dao Saint couldn't answer (the Dao Saint's voiceover said, "We are the Holy Order, not the Immortals!").

Tutor Ya'er was choked by Yuan Xi like this, and she couldn't answer, so she said helplessly: "I don't think this question can be stalemate, something that even Dao Sheng can't think through (Dao Sheng's voiceover: Don't take the old man as an example!), why waste our time here!"

"No, I suddenly have an idea, it's about the destruction and birth of the universe!" Yuan Xi raised his hand to stop Ya'er's words, his dream memories were constantly emerging, and finally Yuan Xi slapped the table and shouted: "Big Bang! The Big Bang Theory!! I remember! There is also the law of entropy increase!! which indicates that all things return to the law of entropy increase!!"

Ya'er was shocked instantly, she was not shocked because of Yuan Xi's words that she couldn't understand, but because Yuan Xi was able to come up with an explanation from nothing, out of nothing! Even if it was wrong, Yuan Xi could actually put it forward, even the Dao Saint ...... Forget it, don't cite his negative teaching materials, anyway, from the ancient times to the prosperous era of China, all the transcendent masters of the Holy Realm, as well as the strong people like Emperor Yuan Yi who were enough to destroy the immortal realm ten thousand years ago, can't answer the source of this world, let alone the infinite universe starry sky above our heads!

Yuan Xi continued to say excitedly: "The Big Bang Theory, in my dreams, there are quite a few people who accept this theory, of course, it seems that there are theologies such as the creation god, I am not impressed, so I will say that this Big Bang came first, well, let me use the simplest words, Ya'er, what you say is nothing, that is, nothing, in my dream, nothing is the singularity!"

"No, it's not that there is no temperature, it has!"

"No, it's not that there's no space, it has it too!"

"So, nothing is something!"

"No, I call it a singularity here, a singularity, it is a point with infinitely small volume, infinite density, and infinitely high temperature!

Yuan Xibi demonstrated: "Nothing is this point, and then one day, no, no, it's not right! That's not time and space at all! Well, this singularity it doesn't know why it can't stand it, yes, it says Lao Tzu is gone, I want to decompress, I want to breathe!"

Yuan Xi made a gesture of stretching his hands, which made Ya'er laugh coquettishly, "So, this singularity began to explode, at this moment, yes! In an instant, because there is time and space, this singularity with infinitely small volume and infinite density exploded like this, and then this universe was born!"

"However, there were no stars at that time, there were no us, there were countless dusts at that time, and their temperature was still hotter than a few suns in the sky, and then, after countless billions of years of cooling, yes, Ya'er, you remember the word cooling first!"

Yuan Xi continued to say in a loud voice: "Now, I'm going to talk about the origin of the world! Those dust have been condensing for countless billions of years, forming a huge stone, such as the earth under our feet, this star realm, it was born and the dust condensed after the explosion! ”

"Yes, after tens of millions of years of evolution, in that distant primeval era, our human race, all races, and so on were still a single cell at that time (I don't know this term, read the notes!) and then we were in the sea of stars, gradually evolved, and then came up to the land, with the continuous evolution of our ancestors, formed a race with its own characteristics, but we are all homologous! That's right, that's right, that's the birth of the universe and the birth of the world, and the origin of our race, that's it!"

Yuan Xi's eyebrows flew and continued: "After talking about birth, let's continue to talk about destruction, I don't know if there is eternity, or this eternity is only relative, relativity or something, you look at the physics subject notes! This universe has a lifespan, it has been cooling since the big bang of the singularity, yes, just now I asked Ya'er to remember the word cooling!"

Because this universe is still expanding, but we are already in the center or edge of the universe, so we don't feel anything, but this universe will die one day, it may be that the entire star realm is turned into ashes for this universe is only a second, but time does not exist in the first place, it is just that we artificially add it as a unit of measurement!"

The young man took a long breath and concluded: "The "law of entropy increase" I mentioned at the end indicates that the "law of entropy increase" that indicates that all things return to extinction, in fact, the irreversible flow of heat from high-temperature objects to low-temperature objects!

I'll give you an example, if a cup of hot water is left for a long time, it will cool down, right! That is to say, the countless starlight above our heads will all be extinguished one day! And if the human race is still there, there is no temperature, it will be frozen to death by the extreme cold, and before the sun is extinguished, even the Northern Wilderness, which is known as the Extremely Frozen Domain, is just a little cold......

In the future, this scene will happen in countless billions of years, not only in the Star Realm, but also in the Eternal Immortal Realm, and in the Otherworld, all of which will return to nothingness......

From birth to death, from existence to nothingness, I think the so-called Heavenly Dao cycle refers to this meaning, heaven, not God, not rules, heaven is nothing, that is, there is, that is, from nothing to existence, from existence to nothing, which is calculated in billions of years, that is, epoch time, is the cycle of Heavenly Dao!"
