The trial of wind and thunder can be described as nine deaths and one life. Now that I know what kind of "soul union" I still have to perform, I will inevitably resist in my heart. Feng Xing said: "I just died nine times, how to avoid the attack of that monster, to be honest, I can't tell you clearly, if you don't tell us some hidden secrets now, I'm afraid our cultivation will also be more auspicious." ”

Thunderfall thought of the dangerous situation he was in when he faced the Sunwind Beast, so he also sided with Fengxing, and said to Yinxian, "Fengxing is right, it's time for you to tell us something. ”

The wind ghost and Yinxian didn't speak, but Qingmeng took over the topic: "Oh, two big men, mother-in-law, mother-in-law, this girl didn't know anything, and she didn't succeed in 'soul union'? Qingmeng's words really startled Lei Xing and Fengxing, I thought that Qingmeng was the same master as Yinxian them, but I didn't know that she was actually the same as herself, and she was also a chess piece, but this chess piece went faster and farther.

Feng Xing smiled faintly, turned his back to Qingmeng and said: "The cultivation of the young girl is naturally much higher than that of me and Lei Luo, then please ask the Qingmeng girl to tell us what this 'Mustard Seed Bodhi Realm' is, and how can we go to the 'soul union'?"

Qingmeng smiled and said, "Why, Fengxing, don't look at me when you talk to me, I'm afraid that this girl will eat you." Witnessing Fengxing's embarrassment, Lei Luo wanted to laugh very much, I'm afraid Feng Xing had also suffered at the hands of this tricky and eccentric Qingmeng like Lei Luo, so he didn't even dare to look at her eyes. Qing Mengmeng still didn't speak, and he was even more happy, he leaned back and smiled and said, "Hey, it's not difficult for you, I didn't tell you before, I was afraid of scaring you." Or if you don't reach a certain stage, you won't believe it. Now, after you have succeeded in your two trials, I will tell you what is going on in this 'Mustard Seed Bodhi Realm' and the 'Universal World'. ”

Qingmeng took two steps on the snow before he said slowly: "Prick up your ears and listen, be mentally prepared, don't stare your eyes out." ”

Teacher Xuanqing once said to Lei Luo: "This world is so big, and it is so small. So big that no one can tread every inch of land, as small as a day, you can reach any corner of the world. ”

Lei Luo is always puzzled by this, saying that the world is very big and easy to understand, but saying that the world is small and can reach any corner of the world in one day, Lei Luo is unpredictable and has a deep meaning.

Lei Luo received the education of Teacher Xuanqing since he was a child, and learned that the composition of the world includes mountains and valleys, plain basins, rivers and oceans, and continental territories......

Teacher Xuanqing has never explained the concept of "Huanyu", and Lei Luo once believed that the world is everything that our eyes can see, and every inch of our steps can go.

Therefore, it has always been Lei Luo's biggest dream to travel around the world, to trace the pyramids in the rainforest, to find the traces of the Pagbalha Temple, to feel the splendor of the Great Wall......

"How ugly is life for a hundred years, and the yellow sorghum has to be hasty. "Once upon a time, people knew their destiny in this way, and they were crawling and rolling in the little square inch of land they were in. Almost most people's lives are engraved in a mold, and the space in which the life produced by the same program is what we call the world.

After Qingmeng's narration, Lei Luo thought of a philosophical proposition: If you know more, is it unfortunate or lucky? If it weren't for the turtle telling the frog at the bottom of the well that there is still a sea in the world, the frog's life would be satisfied with the joy of a well and live happily all his life. I know more, is it misfortune or luck? Recent encounters have made Lei Luo completely lose confidence in real life.

If Yinxian did not take Lei Luo into this magical world, with Lei Luo's knowledge, he would have gained fame, formed a warm and happy family, got rid of that poor country, and returned to his hometown with glorious ancestors...... And now, is Lei Luo lucky or unlucky?

Bruno was lucky or unfortunate to be burned to death in Campo de' Fiori in Rome because he knew too much and was convinced that what he knew was right?

"I also have a good heart, although I still have no regrets after nine deaths. "Now that you've faced it, let's take it calmly. Confused, ignorant, and restrained, how can it compare to the short-lived, but dazzling brilliance?

In the ice and snow, the fate destined to transcend the object, in the explanation of Qingmeng, gradually revealed its magnificent original appearance.

The huge world we live in is divided into eight realms, corresponding to the eight hexagrams of the eight trigrams. There are different races living in all walks of life.

What you see with the naked eye is only one of them, that is, the world in which human beings live - the realm of reincarnation of the five elements. The five elements are metal, wood, water, fire, and earth, which are mutually reinforcing and encompassing all things on the earth. It is still a hundred years of life, reincarnation and rebirth, all of which are called reincarnation. Of course, whether life can be reincarnated or not, Lei Luo can't say clearly, but since this world is defined in this way, it naturally makes sense. This world is the foundation of human life and survival, and thunder and wind are naturally no stranger. I wasn't surprised to hear this, but it felt a little weird to name this beautiful world after this strange name. However, the real sense of the "reincarnation of the five elements" is actually much broader than the earth that human beings understand, which is a later story, and will not be shown for the time being.

And the "Mustard Seed Bodhi Realm" is not among the Eight Realms, it is a unique realm. It is subtle, but in fact, it is not beyond the cognitive scope of Lei Luo: the east, south, west, north, upper and lower six directions are called Liuhe, which is somewhat similar to the "Eight Desolations" in definition. "Mustard seeds" are the seeds of mustard greens, which are small and round, mostly black and white.

"Liuhe" refers to a vast and boundless space, while "mustard seed" refers to a tiny, insignificant and insufficient space. According to Qingmeng's statement: "Liuhe is like a mustard seed, and a mustard is once red dust." It means that the vast and boundless space is actually as small as a grain of mustard, and everything in the world that is as small as dust and grass has a grand world in it.

"Huayan Sutra" cloud: "The Buddha is born with five-colored stems, a flower and a world, and a leaf is the same." Qingmeng's exposition somewhat corresponds to the well-known Buddhist thoughts, so it is not difficult to understand.

The world in which human beings live, the universe defined by existing knowledge, may be, to some extent, just a green leaf, a speck of dust in another world. If this is difficult to understand, then imagine the frog we know, for whom the well is its world, for which it is everything, that it is the limit of its cognition, and for us it is just a small well. Is the whole world it knows, the well, a speck of dust to the earth?

Qingmeng said: "Liuhe is like a mustard seed, and a mustard is once red dust." Although it is not difficult for Lei Luo to understand, what Lei Luo wants to ask is - where is this "Mustard Seed Bodhi Realm" and how to get there?

Unexpectedly, as soon as this question was raised, he was ridiculed fiercely by Qingmeng. She stared at Feng Xing with a smile and asked, "Xiao Feng, can you tell me your opinion?" Feng Xing pondered for a moment and replied: "According to my understanding, since the big world is like a small mustard seed, and the small mustard seed contains the big world, then this 'mustard seed Bodhi Realm' must not have a fixed space, perhaps, maybe at this moment, a flower and a tree, a piece of ice and snow, are all the world, or perhaps, at this moment, we are already in the 'Mustard Seed Liuhe'. ”

These words won a round of applause from the three of them, and Yin Xian couldn't help but speak: "It's really gratifying that Fengxing is so understanding." The understanding is close to the truth, but it is still biased. As soon as Yin Xian said this, Lei Luo and Feng Xing's attention couldn't help but turn to him, and they listened intently to what Yin Xian was about to say. What is surprising is that Qingmeng actually seems to be quite serious, it seems that she is only in the process of "soul union", and she has some understanding of the composition of this world, but she still has no understanding.

And at this time, Lei Luo, who knows that Qingmeng's identity and status are actually so high. So much so that after learning Qingmeng's true identity, Lei Luo and Fengxing were even more afraid of her. This is a later story, which will be explained in detail later.

Yinxian looked at the sky, sighed deeply, and then began to speak, with a sense of reverence and yearning in his tone.

"The world is infinitely large, and the world is infinitely small. Why is there a world, why is there life, or is there a world first, or is there life first? I don't think most people think too much about these questions. If there was a world, then who created it? Where did the world come from without life to create it? If there was life first, then where would life be born? How can life survive without the world to rely on?"

Speaking of this, the sound of the string abruptly stopped, leaving everyone with a rather long blank space, allowing everyone to experience the mystery of his words for themselves. Fragments of jade are flying all over the sky, the world is white, and the world is silent. The five of them stood quietly in this snowfield, each thinking about it, letting the snowflakes cover their bodies, and they were all stupid for a while. The snow grew heavier and heavier, and before long, there were five more snowmen in the deep forest.

If you introduce the string, it is actually equivalent to the proposition of "the chicken or the egg", but the proposition is more huge and serious when used in life and the world. After digging deeper, Lei Luo felt that what he had learned before seemed so pale and powerless in front of this proposition.

(Note: The more popular and authoritative version of the origin of the universe is the "Big Bang Cosmology," which was proposed by the Belgian mathematician Lemaître in 1927.) Lemaître believes that the universe was originally just a superatomic "cosmic egg", and around this atomic cosmic egg, there was a blank space, and all the material energy was concentrated in this cosmic egg, and the temperature and density increased more and more, and finally the Big Bang occurred, forming our universe today. In 1948, physicist Gamow further refined this theory and sketched a picture of the general process of the Big Bang. ）

No one spoke, Lei Luo and Feng Xing, Qingmeng didn't speak, because they didn't know the answer at all, and they didn't know how to pursue it, and the Wind Ghost and Yin Xian didn't speak, looking at their thoughtful looks, it seemed that they didn't know the answer either. Time seemed to stand still, and all five of them were silent in the face of a question beyond everyone's comprehension.

It was still Feng Xing who broke the silence: "In the face of such a grand proposition, we are so insignificant, maybe we have not yet reached the level of understanding the problem - perhaps, let's start with the 'soul union' first." ”

Yin Xian let out a long sigh and said: "Yes, the world is so big, it is so unfathomable and unreachable, in the face of the entire universal world, we can't even talk about the word insignificant. ”

Feng Xing also sighed, looked at the flying snow in the sky, and said: "I think, even if you are a transcendent character, I am afraid that you can't tell how the world is structured, I am popular, and the fate of thunder and rain, I am afraid it is related to this grand proposition, right?"
