"What's here?" Zhengfan Shi became alert.

"Notice! Just now, there was a notice that the third group of people has all arrived, and now the third class of the first phase of the new alliance has been established, Li Daomin, class will be on time at nine o'clock tomorrow, and you must not be late! As soon as he finished speaking, a row of letters appeared on the wall: "Classes tomorrow!" ”

The building where Zhengfanshi lived and a few people lived further east was the sparse Lala building, among which there was an inconspicuous building, which was covered with grapevines, and some ripe purple grapes and unripe green grapes were hung on it.

In one of the rooms in the inconspicuous building, two strong men stood facing each other, both with strange hair growing on their heads, their hair occasionally squirming as their voices shook through the air.

"Alright, let's just let these hostages and our newcomers go to class together!"

"No way!" I saw a more sturdy man walk outside the door, but it was a bald man, holding a turquoise ball in his hand, he put the ball on his shoulder, only to see the ball standing motionless on his shoulder. "I don't agree, we have just enough facilities for our own use! Let them stay on their own! ”

"Xiao Zhi, we have already reported this matter to the above, and it has been approved, not to mention, there is no unpleasant ...... between the private cultivation and our main altar."

"Say no more!" The bald man, known as Xiao Zhi, waved his hand, a little angry, "There is no main altar, but don't forget, in 1700, how many wanted people died in their hands!" Isn't the life of the wanted person? Could it be that the lives of the Wanted fell from the sky? ……”

The bald man became more and more excited the more he spoke......

"Alright, that's it, don't talk about this anymore, the above has already decided, unless you convince the above!" One of the middle-aged men with strange hair interrupted the bald man's words, "Besides, the Wanted People are meant to obey orders, aren't they, for more than a thousand years, the Wanted People have been seriously divided internally, and some have disobeyed the command, and now the above has decided to rectify the circle and not allow the voice of opposition." Today you weren't there, you didn't say anything! ”

"Humph! The king regards his ministers as siblings, and his ministers regard him as his confidants; The king regards the minister as a grass, and the minister regards the king as an enemy! This has been the case since ancient times! ......," said the bald man angrily.

"Presumptuous!" The middle-aged man was furious, "Wang Duzhi, you have to know what you are talking about!" You have to understand your position! Where you stand! ”

"Where do I stand? Where do I stand? There is no beginning......"

"Smack!" The middle-aged man slapped the bald man in the face, "Wang Duzhi, don't say some things, otherwise you know the consequences, especially at this time!" ”

"Good, good! Imam! The bald man didn't say more, but just bowed his hand to the middle-aged man, "However, I won't let those cubs have a good time." With that, he turned around and left.

"Alas! It's still like this! Another middle-aged man sighed.

"No wonder! If it weren't for Wu Duanqi to introduce Xiao Zhi back then, Xiao Zhi would already be dust, how could he not repay the revenge of killing Jie? However, we still have to focus on the big picture, at least at this stage, and pay attention to the small and don't let him go too far. ”

……

After breakfast, the seven Zhengfan Shi people met, and under the leadership of the seven maids, they came to a big tree.

"What a big tree!!" Several people exclaimed.

There were already a dozen people gathered under the tree, most of them teenagers, but there was also an old man.

The men were wondering what kind of tree they were, when a middle-aged man in a leotard jumped down from the tree.

"Alright, everyone, let's start class." As soon as he finished speaking, more than twenty broad roots protruded from the ground, and a group of students sat on the roots.

As soon as the middle-aged man stretched out his hand, a whiteboard appeared on the tree, snow-white, and his eyes were shining.

"What is this? Can anyone answer me? He clicked a black dot on the board.

"It's a little bit." A teenager stood up and said.

"Very well, Collida, I ask you, point, how big?" The middle-aged man asked.

"Dot, there's no size, the smaller the better!" Corida replied.

"Okay, sit down." The middle-aged man nodded. Draw another dot on the board and join the previous dot into a line segment, "What is this?" ”

"This is a line segment!" Huang Yankuo stood up and replied.

"Yes, Li Daojin, you say, how many dots are in this line segment?"

"Infinite!?" Huang Yankuo said unconfidently, because he didn't know what the teacher was going to ask.

"Not bad! It's an infinite number of points! So how many line segments of unlimited length can this line segment be divided into? ”

"Unlimited!"

"Yes, sit!" The middle-aged man used his hand to extend the two ends of the line segment to become a straight line, "This straight line also contains infinite points, right?" ”

He looked at the students below and caught a glimpse of the old man, "Krieg, how many segments do you say this line contains?" ”

The old man stood up from his seat, thought about it a little nervously, and looked at Huang Yankuo again, "Unlimited!" ”

"Yes, sit!" The middle-aged man nodded, "A straight line contains an infinite number of segments, this is an infinity, each line segment can be divided into an infinite number of smaller line segments, this is the second infinity, and any line segment contains an infinite number of points, this is the third infinity." ”

"Everyone, you are from the Inner Self, Erdaozi, Zongyishi, Yin and Yang Harmony Dao, according to the leader's arrangement, today, by me, the content I am talking about is called infinite!"

The middle-aged man stepped forward, "Although it doesn't involve your cultivation, it will open up everyone's minds!" I hope today's lesson will be enlightening to you. ”

"For example, on the white screen, we know that the point is infinitely small, so small that it does not exist, but it exists, and the line, infinitely fine, so small that it does not exist but exists, so the infinite of the infinite is the basis of existence."

The middle-aged man waved his hand, and the white screen disappeared, and a three-dimensional surface appeared. "Surfaces are also infinitely thin, because planes have no thickness, and they don't, but they exist, and they are faces, and faces contain infinite lines."

With a wave of the middle-aged man's hand, the face disappeared, and an almost transparent cube appeared in front of him, "Only space is what we have the most contact with, and space contains infinite faces." So our world is actually infinite, infinite, infinite, infinite, ......infinite, infinite,

The middle-aged man spat for a while, regardless of the confusion and boredom on the faces of the students below......

"Then I want to ask, teacher, are lines made up of dots?" Xu Zhuanwei was very interested.

"Oh no, lines aren't made of dots!" The teacher shook his head, "A line can't be divided into something that doesn't have a length, so a line isn't made up of points." ”

"Then why did the teacher say that there are dots in the line?" Xu Zhuanwei asked.

"Xu Zhuanwei, you asked very well, this is one of the rules of nature, the world is impermanent, there is nothing, there is nothing, the line naturally contains a point without length, but it cannot be divided into a point without length. And I ask you, is there a line in the world? The teacher asked.

"Teacher, there are lines in the world, but you can't see them, as you said, the world is impermanent, there is nothing, there is nothing, the line is abstract and concrete, infinitely long, but infinitely thin, long to no end, so thin that it is invisible, immeasurable, unusable, but still contained in space. However, points, lines, and planes are all abstract images, and they do not exist in the world, so can they also be said to be true if they exist in terms of non-existence? ”
