In the earthen house, Yu Zai was talking about geology with Wenming and Emperor E, a large wooden board was erected, and several used wooden boards had been placed around Yu Zai, and several used wooden boards were written on it with charcoal sticks, and animal hair was used as a board eraser.

And Wen Ming and the two also have the same equipment, but their wooden planks are much smaller than those of Yu Zai, and the charcoal rod is just a stick head, which is convenient for sitting.

Two boulders, three people, a pile of planks.

Wen Ming had never heard those novel sayings, and the whole person was hungry to learn, but it was Emperor E, who learned to learn, and gradually began to understand.

While thinking and understanding, the charcoal stick fell to the ground.

Yu Zai just erected the fifth plank.

Emperor E bowed down to pick it up, and then sat up again.

She was stupid.

“...... When rock formations are formed, they are generally horizontal. Under the action of tectonic movement, the rock layer is bent due to force, and a bend is called folding, and if it is a series of wave-like bending deformation, it is called folding...."

"And then what is tectonic movement, simply put, it is the emergence of a force in the earth, which leads to the displacement and deformation of the earth's surface and mountains, and even the entire rock layer.... Embodied in the outside world is a huge earthquake .... And folds, fractures, trenches, mountains and deep valleys are all guided by this force....."

"The so-called 'high bank is a valley, the deep bank is a mausoleum', and even 'the mountain has no mausoleum, the river is exhausted, and the heaven and earth are combined', these are all situations that may occur in geological activities.... What we know is a thousand years.... Geological activity is often calculated on the basis of thousands or tens of millions of years..."

"These numbers, the witches of all tribes should have been taught, there won't be any..."

Yu Zai drew a whole picture of the wooden board on the big wooden board, and then circled the entire knowledge point with charcoal!

Emperor E (dementia).

She bent down and picked up the charcoal stick, how could it be like this!

Teacher, can you quickly rewind x16!

"Okay, do you understand!"

Yu Zai asked the two, and Wen Ming responded: "I understand." ”

Emperor E: "I didn't...."

Yu Zai: "Okay, let's move on to the next key point of knowledge!"

Emperor E was speechless, why did it become like this, although he said that he would not be able to keep up with the progress when he was distracted in class, but he just squatted down and picked up the pen!

Emperor E suddenly felt a little resentful in his heart.

You can't do this to me if I'm a bad student! And there are only two students in total!

In short, a large class is out of class, Yu Zai said that the break between classes, if you need to go to the toilet, you can go now, Wen Ming immediately said: "Brother Zai, what is the geological phenomenon of the mountain without a tomb?"

The teacher was very happy to ask questions about the courseware, and Yu Zai did not hesitate to answer at this time: "This is the phenomenon of weathering and handling." ”

Mountains and mountains have no tombs, this is not from Ziwei Erkang's Qing Dynasty romance drama, and Qiong Yao also changed "Ling" to "Ridge", in fact, in the poem, the meaning of Ling is "mountain", so this is an act of painting snakes.

This poem is a famous passage in the Han Dynasty Yuefu folk song "Shang Xie", and "Shang Xie" is one of the "Eighteen Songs of the Cymbals", which belongs to Yuefu's "Propaganda Songs".

The full text is: "I want to know you and live a long life." The mountains have no tombs, the rivers are exhausted, the winter thunder and earthquakes, the summer rain and snow, the heaven and the earth are combined, and you dare to be with the king!"

However, mountains and rivers will really disappear, Shanwuling is a famous weathering and transport phenomenon, when it comes to weathering, everyone should be no stranger, that is, it is eroded by nature, the rock is destroyed, disintegrated, corroded, and the remaining dust is transferred out by wind, water, clouds, glaciers, gravity, etc., which is transportation.

So after tens of thousands of years, if there are continuous disasters in heaven and earth, then it is likely that the mountains will disappear, the rivers will dry up, and the whole world will change.

After Wen Ming got the answer, he was immediately amazed.

"Heaven and earth have such great power, and the so-called great ability of wizards to move mountains and seas is just to use a small part of the power of heaven and earth themselves, and immediately use it..."

"It's just shortened the years, and weakened the power, so it's far less powerful than the changes of heaven and earth itself..."

Wen Ming sighed, and Emperor E was finally able to speak, it was not okay to ask questions, but she could raise the bar.

Although Emperor E doesn't want to learn from her eldest brother, at this time, she does have a big problem and must vomit quickly.

"How do you know that? If it's really based on a thousand years, 10,000 years, a hundred thousand years, a million years.... I don't even dare to imagine that kind of long time, since ancient times, Guangchengzi and Bai Zigao have lived for 1,500 years, and Yu Huazi has lived for more than 2,000 years, but their age is not worth mentioning at all before such a long time!"

As Emperor E himself spoke, he couldn't help but feel a deep sense of awe in his heart.

Reverence for the nature of heaven and earth!

Yu Zai nodded at this time: "Good question! This is also the key I am going to tell you!"

"Weathering can be seen when the usual sand is blown up by the wind, while in the deserts of the west...... The geological phenomena are as follows.... Sometimes you can get the whole picture from a small perspective, but it's best to go on a field trip......"

"Here I would like to talk about the issue of geological age, for example, I met a person who found the fossil of a sea shell in the mountains and rivers....."

Yu Zai's voice gradually left his ears, and Emperor E fell into his own inquiry and thinking.

Reflections on the years.

At this point, the years suddenly seem long.

"Longbo people, in ancient times, there were 18,000 years of life, but in the face of the changes of heaven and earth, they were just a basic unit, Guangchengzi They are even only one-tenth of a 10,000-level unit, and they belong to the foundation of the foundation.... And the big Tsubaki tree, which is 8,000 years for spring and 8,000 years for autumn, also seems incomparably small in this span of years....."

(Yu Zai's voice: "I met a god named Zhuhai, who came back from the East China Sea and said that he saw the people of the Mingyi Group measuring the tides, and found that the rise and fall of the tides are related to the waxing and waning of the moon, so there are knowledge points everywhere in life, and you just need to be good at observation..... ）

At this moment, Emperor E suddenly understood why many of those Qi Refiners advocated the rule of inaction, why many people liked to hide in the world, and why, they were extremely eager for immortality....

Because in their age, a hundred years and a thousand years, like a dream, but a big dream, watching the changes in the world, the old people are getting old, and their hearts are gradually numb, only those who are also qi refiners can feel a trace of the "truth" of being human beings with each other, and they have been immortal, so they know more about the longevity of heaven and earth, how leisurely!

(Yu Zai's narrator: "Wen Ming, as long as you observe carefully, you are the new Leeuwenhoek... Ah you ask me who he is, he is a man of God who observes meticulously, he squints and looks at the world with the tip of a needle, have you heard, Leeuwenhoek does not open his eyes, he opens his eyes to kill .... ）

Ten years of planning, a hundred years of work, a glorious state, and a prosperous tribe, in the eyes of the Qi Refiners of the Birth Sect, it is really just a dream, and after a hundred years, these dreams will be shattered, and then collapse into yellow dust.

So nothing has changed, only the quiet world is silently telling everything in the past!

Emperor E suddenly lost his mind and felt the sadness of "I was born as a human being, I am sorry".

(Yu Zai's voice: "Hey, Ah Huang, what are you doing, it's class.... Have you listened to the lecture!")

She was immediately depressed.

There's still a point in being alive and having a fart!

"Just like the cicada, born in a hurry, died in a hurry, singing in summer, and I don't know that there is spring and autumn!"

Emperor E said a word in great depression, and Yu Zai, who was about to scold, heard it, and waved it in front of Emperor E with a wooden ruler on the spot!

The sound of a snort woke her up, and Yu Zai said directly: "You are feeling that your eldest brother! The adult cicada can only live for eighty days, but its larvae can live underground for three years, and there are also two kinds of cicadas, one can live for thirteen years, and the other can live for seventeen years, who told you that cicadas don't know spring and autumn!"

"Don't study hard just because you're handsome!"
