The snow does not freeze, and the sting does not open.

Bucket fingers, heavy snow.

The heavy snow season is divided into three waits, one waits for the crane to not sing, the second waits for the tiger to start handing, and the third waits for the lily to stand out.

It is said that at this time, because of the cold weather, the cold trumpet bird no longer chirps; at this time is the heyday of yin energy, the so-called prosperity and decline, yang energy has sprouted, and the tiger has begun to have courtship behavior; "Li Ting" is a kind of blue grass, feeling the germination of yang energy and pulling out new shoots.

But in the south, of course, it doesn't snow.

As the day gets warmer, even the place where you could still see the scattered small snowflakes is now gone.

It was pouring rain and the sky was dark and the clouds were low.

The water level in Mizusawa is rising, and this heavy rain is coming just in time for the completion of the Great Weather Observatory.

Hazy sinking into the world, the already huge meteorological observatory is more and more towering into the clouds, and the beasts in the mountains and fields in the distance, seeing the huge mountain-like shadow in the distance, inexplicably give birth to worship and awe from the heart.

A huge black snake arrived near the Great Weather Observatory, he raised his head and looked at the great building, a pair of snake eyes were dull for a while, and then quietly approached the Meteorological Observatory.

In the northern part of the public field, near the flood distribution area, there were many people dressed in robes.

Yu Zai is also among them, Ying Long is also among them, plus Chongbo, Zhu Rong, Changqin, Uncle Xi, and the wizards of the Yaoshan clan, etc., the people here are all people who participated in the construction plan of the Great Flood Control City.

Chongbo is the main hydrological survey, Changqin is the main record, Zhurong is the main stone, Uncle Xi is the main astronomy, Yinglong is the main wind and rain, and the rest of the Yaoshan master is calculated with data, and some other people, such as karma, will help the Yaoshan clan.

Red pine nuts, the main finger pointed.

This is a god-sent heavy rain, and the direction of the water potential can be observed, so it is inevitable.

"Data from field trips is a crucial ....."

Of course, this so-called advanced method is actually quite primitive in the later generations of Yu Zai, but it is definitely much more accurate than the measurement and calculation method of this era.

A stone monument was carried over and embedded in the hills of the flood distribution area, and this stone monument was very large and conspicuous.

This thing is called the "water rule".

Coupled with facilities and equipment such as rain gauges, we have long understood that the correct measurement of hydrological and celestial phenomena can bring endless well-being to the tribe, and of course, the basis of correct measurement is advanced facilities and clever calculation and comparison methods, and finally we must add cowhide people.

In this, many people saw the new "black technology" of Yu Zai for the first time.

Level.

In the process of excavating channels and even canals, the water surface is used to measure the height of the terrain, during the Warring States Period, Zhuangzi saw this kind of thing, and said that "the water is quiet and accurate, and the master craftsman takes the law", but the appearance time of this thing is actually much earlier than the Warring States Period, the Spring and Autumn Period, the so-called "what is the level of this person", this sentence, in fact, is from Confucius.

According to Xunzi, Confucius believed that the word "level" was very good, not only to measure the terrain, but also to express the level of a person's skills and knowledge, so he used this word when talking to his disciples.

The ancient level, this set of measuring tools, is composed of three parts, namely "level", "illumination plate", and "degree rod".

Of course, this thing, in the era of mountains and seas, is simple and easy to learn, but from such a simple, it will measure extremely magical results, as soon as this thing comes out, Chongbo used it for a while, and immediately couldn't put it down.

People's hobbies are always weird, but men's hobbies are the same, science students like delicate instruments, and liberal arts students like figurines.

The plan for the flood control city has been implemented soon, and this heavy rain is the best on-site investigation.

The busy people gathered and dispersed, their clothes swayed, their utensils were brought with them, and soon they gradually disappeared into the hazy smoke and rain.

"Man sees himself as a part of heaven and earth, but he also painstakingly ponders the changes of heaven and earth, and well-being and disasters are often hugely linked. No, for all living beings, they must tremble and walk on thin ice. ”

Yu Zai's voice was very soft, and he and Chi Songzi talked to each other, so the teacher asked rhetorically, if heaven and earth care about every living being, then Tianli should not exist.

It is precisely because of the breadth that it can accommodate all living beings and many colors of all things.

"Because heaven and earth don't care. ”

When they left, they saw a lot of cattle and sheep appearing in the distance, and some people were driving those cattle and sheep to come here from the direction of the river.

On the other hand, Shu Jun and Xianlong, they also saw the people who were busy here before, those people were wearing robes and hats, these things have spread, and the Central Plains originally had similar humble products.

But what really confused and puzzled Shu Jun and Xianlong were the tools that the people in the south took away.

They came to a piece of land in the flood distribution area, and saw the huge water monument, leaning diagonally, or rather embedded in the edge of the mound.

There are many scales recorded on it, and there is a huge Cangjie character on the back.

At the top, there is a "danger".

Wei is the name of an ancient god, this god is the guy who harmed the cave, and later made himself a stone man by death, and was suppressed for at least 2,000 years.

"Danger, it's a sign of a great murderer, is this something to measure the water level?"

"It's just a water tablet! What are you surprised about, isn't it just a matter of having a hand to engrave this?"

Xianlong snorted twice, deciding that this thing was not what he wanted to see.

If you have a hand that can carve something, I can do it too.

Shu Jun is a little interested, when he was young, he once participated in the sacrifice to expel the drought, at that time he walked to the west with a willow branch, and shouted to the gods to go north as he walked, and in some places, similar things were used to measure the water level, but it was usually a bamboo pole or something.....

As soon as they arrived in the south, they didn't expect to bump into what the south seemed to be doing, and such a professional movement reminded Shu Jun of the people at the observatory in the land of Taotang.

That is, although I don't understand it, I know that you are very professional in this one.

The sound of cattle and sheep came and went, the cattle were better, the sheep obviously did not like the rainy weather, even if they were covered with a large piece of turf, the sheep and sheep were still very unhappy.

Xianlong was also very unhappy, and began to urge Shu Jun to move quickly, but Shu Jun suddenly said:

"Xianlong, you go first, I'll observe ...... here"

"Ahh

Shu Jun pointed to an instrument on it, which was placed here alone.

That's a rain gauge.

.........

The rain began to lighten, and by the time they arrived at the public field, the muddy road was already full of people.

The black clouds dispersed, and the light fell in a scattered manner, and people saw the fertile soil bathed in light.

Look in the distance in the direction where the dawn is.
