But what is it

She restrained her rambling look and began to think seriously.

At the beginning, she found the textbook of astronomy. Out of preconceived ideas, she thought that the key to opening the password box would be related to Astronomy

But it turned out that it had nothing to do with it. Instead, the chemical knowledge in the portrait gave her the real answer.

The director's team spent so much time arranging astronomy just to disturb her vision?

Is that reasonable?

Did her fingertips hit the edge of the box

Suddenly, her eyes rested on a model of Professor Smith's desk.

The model is very common. At first glance, it looks like the wall of the great wall of China.

There are 12 concave and convex gullies in the city wall

Li Qinian picked up the model and looked at it 360 degrees. He didn't find the engraved font.

"Director, you are really... The sword is on the wrong side."

She suddenly opened her mouth to the radio.

[Woge, what's the matter?]

[what's wrong with this model? Isn't it the wall of the Great Wall?]

The director silently raised his hand and wiped his sweat. He didn't dare to say anything

"At first, I thought everyone entered the secret room at random, but now I find that everything is carefully arranged by you."

Li Qinian gradually had an answer in his heart.

"Other people might not be able to get out of this secret room."

【???】

【???】

All the bullets are question marks.

My college entrance examination score is 711. I have been praised by others since childhood. Now I feel like a fool...]

Li Qinian raised her eyes and looked at the clock on the wall. This time, she patiently explained to everyone:

"The clock on the wall hasn't moved since I entered the room."

September 15, 1980

6:00 am

"At first I thought the clock was broken, but now I think everything is a hint."

As she said, the people in the director group wiped their sweat madly across the screen.

you bet.

Everyone's room is arranged in advance.

Li Qinian entered the room with the theme of "astronomy + chemistry" because they knew her background and knew that she was a student in the Department of astronomy.

This chamber of secrets is tailor-made for her.

Li Qinian continues to explain.

"The model in my hand is not the great wall of China at all, but from the tower site of changjiluo - the 13th tower of changjiluo."

This model just has 13 raised walls and 12 depressions, which are called thirteen towers by scientists.

"We all know that the earth has been rotating, and the sunrise point on the horizon is also changing during the year, and these towers in changkiro fully correspond to the sunrise point..."

[... It's all human words. Why can't I understand it?]

[why did the earth start rotating? Shit! Isn't this a simple puzzle game?]

"The twelve depressions between the towers correspond to twelve months of the year in turn. The date on the wall stays on September 15, September... In September, the sun will rise slowly from the fifth depression."

So the position where the red laser pen should shine is just at the fifth depression.

She rubbed the tower model in her hand and suddenly tilted her head. She held her head and looked at the camera carefully:

"You may feel a little bored. Why do a group of people want to build such a tower just to make sure what day it is today?"

As long as you stand not far from the tower at sunrise, you can determine the approximate date of the day by observing the location of the tower when the sun rises at sunrise.

In short, changkiro is the ancient calendar.

"Today, with the development of science and technology, when we pick up our mobile phone, we can know the specific time today, but thousands of years ago..."

Thousands of years ago, the ancients did not have any modern equipment, watches or mobile phones. How do they determine the passage of time?

"More than 2000 years ago, people living in changkiro regarded the sun as a God."

"Every morning, thousands of people gather in front of the thirteen towers, waiting for the sunrise, waiting for their gods, looking pious and respectful, and thanking the sun for giving them a new day..."

Without any modern construction equipment, they piled up such a thirteen tower with yellow sand and stones 100% by manual force.

"Among the many ruins on the west coast, the long kirota building is not amazing, but for me, this is an unparalleled place..."

Li Qinian's eyes were complex and deep, and his tone was a little erratic:

"Because this is the first time that human beings use their own strength to measure the kingdom of God."

A group of uncivilized ancients tried to explore the laws of nature with their own strength for the first time.

Here is the birthplace of civilization.

"Maybe for you, the knowledge in textbooks is readily available. Primary school, middle school, University, mathematics and chemistry students... A set of knowledge system that adults should master has been established.

When you open the textbook, you can know why the sun rises in the East, why 1 + 1 equals 2, why the PI is 3.1415926, and the refraction of light

You think these are common sense.

But without the pioneers of exploration, human civilization could not be as perfect as it is now. "

The barrage became quiet unconsciously, and even the recording staff standing aside turned serious.

Thousands of years have been too long for them to imagine what human society was like in the past.

"We all know the theory of the earth big bang 13.7 billion years ago. We know that the earth was born and human beings were born... But at the beginning, the ancients only knew that Pangu opened the world and Nu Wa made people by kneading earth."

"We can clearly see the real shape of the earth through satellite photography. The blue mercury is very beautiful and dreamy... But at the beginning, many people thought the earth was square."

There are too many conclusions that modern people sound absurd and ridiculous.

It is precisely because of these absurd conclusions that they have been piled up step by step, leading mankind to the summit of civilization.

[... Is my tear point too low? I actually want to cry]

[after searching the photos of the thirteen towers, it's very common, very common, just like small piles piled up randomly in the desert... Who could have thought that this was once the place where humans shook hands with gods. The yellow sand buried all the prosperity, but could not bury the aspirations of the pioneers to seek up and down]

[hybrid rice is also the crystallization of human wisdom. Grains of rice everywhere in supermarkets are bricks and stones in the famine era]

[it's nice to live in such a peaceful age]

[sobbing, sobbing, son, you are so introverted and educated that you are not used to it!]
