It took half a year to change the reading room one after another, and the floor to floor. Today, it's time to go to Reading Room 7 on the 7th floor of the Universal Museum.

When Ye Feihua, He Shannon, and Yun Dan walked into the No. 7 reading room on the seventh floor of the Huanyu Pavilion, the three of them couldn't help but be slightly stunned.

The librarian behind the mahogany counter turned out to be the old man in gray who was presiding over the lecture just now.

Ye Feihua and the three of them came to the counter, bowed to the old man in gray, and silently selected a few classics.

After taking the book from the old man in gray, Ye Feihua and the three of them bowed down again, and then found a futon nearby and sat down cross-legged.

is still the same rhythm, Yun lightly picked up a classic book, and sat for a long time. Ye Feihua and He Shannon were holding the classics in one hand and turning the pages with the other, their movements were quick and neat, and after a while, the two of them went to the mahogany counter to exchange the classics, and so on.

Time is silent, flowing with traces.

Sunrise, sunset.

Ye Feihua and He Shannon don't know how many times they have to exchange the classics every day, but they can't find the information they are looking for. Today, it's still the same.

Just when Ye Feihua was changing the classics for the twenty-ninth time, the gray-clothed old man behind the mahogany counter suddenly smiled.

"Recently, I heard from a colleague that there were three young people in the Nebula Library, and two of them read ten lines at a glance, and the reading speed was extremely fast. These two are the two of you, right? The old man in gray asked.

"Let the master laugh!" Ye Feihua smiled and owed a debt.

"What book did you just borrow?" The old man in gray continued to ask.

After Ye Feihua heard this, she held up the classics.

"It's not yours, it's the previous one." The old man in gray said.

"It's a brief description of time and space written by the Master of the Cold." Ye Feihua replied respectfully.

"What did you say? Pick out the essentials and listen to them. The old man in gray said.

When the gray-clothed old man spoke, he never looked up, and his eyes kept staring at the light blue light curtain of the book index. Although the tone of the old man in gray was very light, there was a firm taste in his words, and Ye Feihua couldn't resist at all.

Ye Feihua recalled for a moment, and then said: "Master Snub said that in terms of the history of life evolution, ......"

"Slow down, say slow." The old man in gray raised his hand.

Ye Feihua smiled, followed the wishes of the old man in gray at the moment, slowed down his speech, and began to speak.

A Brief Introduction to Time and Space mainly expounds the relationship between time and space. The essence of time is the continuity between the first and the last, with a beginning and an end, and no beginning and no end. Space, or the universe, is commonly known as the universe. In the universe, time is a circle, a cycle that goes on and on, with no beginning or end, and everywhere there is a beginning and an end. The history of the evolution of life is a tiny point in the time circle, so short that it can be ignored......

Ye Feihua has a clear mind and is very organized.

When Ye Feihua finished speaking, the old man in gray looked up at Ye Feihua, and a trace of surprise flashed in his deep eyes.

"Not bad!" Looking at the young man in front of him who was docile and elegant, with a quiet atmosphere, the old man in gray sighed sincerely.

The gray-clothed old man stared at Ye Feihua for a few moments, then his face turned pale, and he asked, "What are you looking for when you change the classics so frequently?" Let's hear it and see if the old man can help you. ”

"I've always been confused, and I've been thinking, what is the universe? What is life? Ye Feihua directly raised a question.

"The origin of the universe is energy, and energy is the most basic unit of the universe. In this heaven and earth, everything is made up of energy, and everything is just a different combination of energy, tangible or invisible. The primordial universe was an infinitely hot energy body that exploded and expanded. In the process of continuous expansion of the primordial universe, the cooled energy continued to gather and combine, forming the sun, moon and stars, all things in heaven and earth, and generating the first life, and then, evolving countless life. The evolution of life, like life itself, has a process of gestation, growth, maturity, aging, and death. As the circle of time rotates, life fades away again. Finally, at some point in the time circle, life disappears completely. This is the history of the evolution of life. After countless years, the first life appeared, then countless lives, and finally, those lives disappeared completely. In this way, countless histories of the evolution of life eventually appeared in the time circle. Life appears, life annihilated; Life appears again, life is annihilated again; And so on and so forth. The history of the evolution of life is just a negligible episode in the long life of the universe. The history of human civilization in the Star Continent is just a tiny fragment in the history of the evolution of life. The origin of heaven and earth is the circulation and transformation of various energies, which can be transformed between various forms, and decay and continuous consumption in the transformation. The process of life is a process of continuous transformation and consumption of energy. The evolution process of human civilization is a process in which the human race controls and uses the energy of heaven and earth. Plunder and strife are the driving force behind the continuous progress of this civilization. The old man in gray said.

"Thank you for your advice! Teachable! Ye Feihua bowed slightly.

"In the cultivation world, the process of cultivation of monks and magicians is also a process of controlling and using the energy of heaven and earth, but for monks and magicians, it is more about advocating the development of their own potential, and controlling and using the energy between heaven and earth with their own potential. The universe is vast and unpredictable, and there may be some life, and the energy of heaven and earth can also be used to the fullest with the help of external forces. The old man in gray said.

"What does the master mean is that there are other beings in this universe?" Ye Feihua asked.

"That's nature!" The old man in gray nodded affirmatively.

"So......" Ye Feihua pondered for a moment and asked, "May I ask Master, what do you think of other life in the universe?" ”

"In the universe, all stars are the same, as long as it is life, all are equal. From humans to ants; It doesn't matter if it's grass or moss, it makes no difference! The old man in gray smiled indifferently.

Listening to the words of the old man in gray, Ye Feihua seemed to have relieved some kind of burden, and her heart was inexplicably more relaxed.

"It is said that the elven race is from outside the sky, since there is such an example, there must be countless civilizations in the vast universe!" Ye Feihua sighed.

"yes!" The gray-clothed old man smiled faintly and said, "The elven race comes from outside the sky, showing a magical civilization that is completely different from the human race's fighting civilization. Based on the magical civilization of the elves, the human race has also evolved a splendid magical civilization, which fully proves the wisdom of the human race, but it also proves the wisdom of the elf race. The elves came from outside the world, and in their native land, it was impossible to imagine how great and brilliant their magical civilization was. The arrival of the elves is enough to prove that there must be diverse civilizations in this universe, and it is also enough to prove that in this universe, our planet is too small. ”

"The elves come from outside the world, but how did they get here? I've been struggling with this question. Could it be that they flew and flew all the time in a flying machine, through the deep and undetectable universe, and flew directly to our planet? Ye Feihua asked.

"That's right! It's just flying and flying! The old man in gray nodded.

The gray-clothed old man glanced at Ye Feihua, and then said: "However, traveling in the universe, flying is only the most basic, even if you fly fast, faster than the light, you can't fly far." To go from this galaxy to another galaxy, the most important thing is to jump from time and space, constantly making time and space jumps, jumping from one time and space to another. In this universe, there are countless eyes of time and space. The Eye of Time and Space is a naturally existing teleportation array at the beginning of the birth of the universe, and it is a cosmic-level magic teleportation array. With the help of the Eye of Time and Space, it may only take a few minutes to jump from one galaxy to another. However, after entering the eye of time and space, there is a very serious problem, that is, the coordinates of the galaxy. Without accurate galaxy coordinates, you will definitely get lost in the vast universe. ”

The voice of the old man in gray was very light, but the words spit out by the old man in gray fell into Ye Feihua's ears, but they were tantamount to thunder.

The originally completely desperate state of mind was like the dry soil that had been dry for thousands of years, and at this moment, it was very unexpected to drench a drop of hope, Ye Feihua's heart couldn't help beating wildly, and a strange flush appeared on his face.

"Master! What is a time jump? There are also Eye of Time and Space and Galaxy Coordinates. Can you elaborate a little bit more? Please advise the master! Ye Feihua suppressed the excitement in her heart and bowed to the gray-clothed old man.

"The jump in time and space, the eye of time and space, and the coordinates of the galaxy are questions that the old man has been thinking about for a long time. It's a pity that for many years, there has been no progress. These problems, on this continent, may only be known to the elves. The old man once tried to contact the elves, hoping to get some valuable clues. However, it has not been possible. These questions are the eternal secrets of the elves! The old man in gray said with regret.

Hearing the old man in gray say this, Ye Feihua couldn't help but be disappointed.

At this time, Ye Feihua suddenly remembered something, hurriedly bowed down, and said respectfully: "Sin! Sin! I haven't asked the master for his name, but I still ask the master to forgive my sins! ”

"It doesn't matter! The old man was just a librarian, with no name. You can just tell the old man to snub him. The old man in gray smiled faintly.

"I've seen the Master of the Snub Shoot!" Ye Feihua reacted in an instant, and her voice became more respectful.

"I've seen the Master of the Snub Shoot!" He Shannon and Yun Dan had already come to the side, and this time they learned that the ordinary gray-clothed old man in front of them was the author of "A Brief Introduction to Time and Space", and the two of them also bowed slightly.

The snub master looked at Ye Feihua, He Shannon, and Yun Dandan, and the smile on his face became even bigger.

"In this world, there are infinite mysteries of fighting spirit and magic, but there are also some wonderful things besides this." The snub master said.

"Please also ask the master to advise!" Ye Feihua said respectfully.

The sunset outside the window was like blood, and it was almost time to close, and there was no one else in the reading room except Ye Feihua, He Shannon, and Yun Dandan.

"The old man has treasured a few things, and they have been on display for many years. The three of you gave the old man an unusually peculiar feeling, and today actually made the old man have an urge to share. Come on! Young people, let me show you. The snub master said.

With a wave of his hand, the Snub Master closed the door to the reading room, then opened a door on the wall and walked in.

Next door to Reading Room 7 is Reading Room 8, separated by only one wall between the two reading rooms. There was a door on the wall, and there was a faint wave of light flowing on the door, like a curtain. Obviously, there is a separate magical space in the wall.

When Ye Feihua walked to the door, she paused slightly, then raised her legs and stepped in.
