"In these years, there are not many people who dare to talk about Gewu in public. This man is a man of great courage. ”

On the other side of the auditorium, a little girl who seemed to be in her early teens whispered. Compared to the adults around her, her delicate dresses and long, straight black hair looked out of place. And her sitting posture with her hands on her chest and one leg flat on the other leg also has a temperament that does not belong to her peers.

"Shhhh......h......h

"What if you hear that?" the black-haired girl tilted her head slightly, "If the truth is not allowed to be questioned, the truth itself will lose its meaning, I don't think that Lord Xia should be so narrow-minded." What do you think, Chichi?"

Chichi rarely shrunk his shoulders, "Chichi...... I don't know. ”

This is really rare, Fang Xiandao raised his eyebrows, he could actually make Qianzhi, who was good at everything, say such a thing.

This person is the old lady's newly sent living dead, a thousand words.

Fang Xiandao has been in the Fang family for more than ten years, and has heard a lot of rumors about a thousand words, but it is the first time he has really seen his true deity.

Of all the living dead, a thousand words can be said to be the most special one. Her age is unknown, it seems that she was born in her ancestors, and in the war against the rule of Eternal Kingdom, many of the living dead died permanently, but Qianyan survived. Not only that, she has never "slept", in other words, she has all the memories from her birth to the present.

In the Fang family, every living dead will become the guardian of the Fang Shi, with the exception of Qianyan. She rarely shows up, and she will tell the old lady and the old lady alone if she has any needs, and she never appears in battle, so there are jokes among the disciples, saying that the living dead protect the Fang family, and the Fang family protects Lord Qianyan.

I didn't expect the old lady to send this special living dead to Jinxia because of a letter of her own. When the senior sister introduced the other party as a thousand words, he was really taken aback.

Could it be that something happened in Lingzhou that he didn't know about?

However, with those two heads of the family in charge, there shouldn't be any major problems.

"Why doesn't anyone dare to talk about Gewu now?" Fang Xiandao asked. In any case, this person is a living annat, and it is not easy to see it, so it is always right to ask more.

"The so-called knowledge of things is to explore the truth of all things, and to ask questions with things, but what is the Tao, there has been no unified answer for thousands of years. Qianyan said in a cold tone, "Let's study it at a young age, there is nothing to say about every grass and tree, brick and stone, maybe the farmers in the village know more than you." If you study it bigger, it is all things, the universe, and luck...... and even the way of heaven. Except for the last one, the rest are things that cannot be seen or touched, and most of the research is full of lies, and it is easy to be caught by people and argue that they are useless. Therefore, in the long run, Gewu has rarely been mentioned. ”

"That...... How long ago did you say this?" Fang Yanni asked cautiously.

"It's been more than 100 years. At least when Yongguo was still around, there was basically no one talking about Gewu among the various academic schools. After all, it's easy to say that it's easy to see the big from a small perspective, but it's not so easy to really find out the connection between the grass, trees, masonry and the universe of Vientiane. In the final analysis, we are just mayflies that inhabit this world. ”

"1. More than a hundred years ago?" Fang Yanni's eyes widened in surprise, "Isn't that older than the ancestor?" I should call you...... Taishi Ancestor?"

When Qian Yan looked at the chief disciple of the Fang family, his gaze softened slightly, "You don't have to be so restrained, the living dead exist to protect the Fang family, and age is not the point." ”

"But you just mentioned the exception of the Heavenly Dao...... Fang Xiandao frowned, "Isn't this thing worthwhile?"

"At least it's not an empty rhetoric. Qianyan stretched, "Otherwise, Yongguo wouldn't have died because of it." ”

"Can you elaborate a little more?" he asked, "and in all the books I have read, its demise is attributed to the tyranny of the Eternal King. ”

This summary cannot be wrong, but it can only be said that it is the surface of each other with the actual reasons. As for the more specific, let's wait until you become the head of the house. ”

"I am not qualified to be the head of the house. Fang Xiandao shrugged, "The head of the family will definitely choose from the senior sister's generation, it depends on who can get the favor of the senior sister." ”

"Oh, I don't think she's—"

"Thousand, thousand, thousand, thousand words, Lord Xia, let's see Xia Fan start teaching!" Fang Yanni stammered.

He finally got started. Fang Xiandao immediately focused his attention on the podium, which made the senior disciple secretly breathe a sigh of relief.

"I want to ask you a question," after a brief introduction, Xia Fan went straight to the point, "Not only the children, but also everyone present, do you think this square is empty or crowded?"

The adult was still a little reserved, and the child had already raised his hand to answer.

"Empty!"

"Crowded!"

"The crowd of people sitting on the chairs, the emptiness of the people sitting on the straw mats!" concluded at the end of the day.

"Why?" Xia Fan asked with a smile.

"Because they have people next to them and we don't. ”

"In other words, if there is only one person in this square, it is empty, right?"

The children nodded in unison.

"What the hell is he trying to say?" Fang Yanni said curiously.

Qianyan closed his eyes disapprenosingly, "It's probably the reality in the virtual, and the reality depends on each other." It seems to be a big truth worth pondering, but if you taste it, you will find that it doesn't say anything. ”

"But I want to tell you—" Xia Fan said loudly, looking around, "you are not empty around you, but like fish, you live in the water. It's just that you can't see the water. Usually, people call it air. ”

The concept of air is not unfamiliar to everyone, and it has long been realized that what people breathe is air, and the absence of air will lead to suffocation, which is not a new statement. However, the world's basic understanding of qi is only a concept.

"So, when I'm walking back and forth, I'm actually swimming, and where I'm walking there are turbulence and whirlpools, and there are waves in front of me because of the collision with the gas. If you run, you can clearly feel the collision – we usually call it style. But in reality, you're splitting through layers of obstacles, pushing the gas forward together. ”

"Don't underestimate this resistance. If you're fast enough, it can even become as solid as a wall, and if you hit it head-on, the air can kill you. ”

Everyone couldn't help but show expressions of disbelief.

"Summer ...... Teacher, are you telling the truth?"

"But even if I ran as fast as I could, I couldn't feel the air stopping me. ”

"That's because you're not fast enough. Xia Fan smiled, "Why don't you think about it from a different angle, what do you think the fish will feel like in the water?"

"It's going to feel heavy!" said one of the children, holding up his hand - I have to say that the previous morning's lessons and guidance had put everyone into a lot, "at least...... I'll feel heavy. When you soak in the water, you have a hard time breathing!"

There was a burst of laughter.

"That's because the water is heavy and weighs on you. Xia Fan nodded, "The same is true of air - it also has weight, and it weighs on us all the time. ”

"Eh, is there one?" Fang Yanni stretched out her hand to support it, "Why can't I feel it?"

Qianyan also opened her eyes in a little surprise, and she vaguely noticed that what the other party said seemed to be very different from the past Gewu.

"Next...... I'll prove it to everyone. Xia Fan took out a big glass and placed it on the podium.
