This shit can't stand it anymore

Chapter 201 Xuandu: I want to learn mathematics! (Second update, please subscribe)
August is still young, and the weather is getting cooler.

Even at noon when the sun was shining brightly, there was no such aching feeling on the skin as before.

Xuandu walked slowly among the groves on the banks of the Huaishui River, specially picking up shade to pass under the shade of trees that the sun could not reach.

The rippling water of the river is running towards the east, and the blue sky looks very high, only a few white clouds are floating in the far distance.

Perhaps it wasn't so hot anymore, and the sound of cicadas was much less.

Ahead is Linhuan Pass.

Xuan Du took a step forward, raised his eyes and looked forward.

A path twists and turns and stretches toward the depths of the woods, with farmland on one side and water canals on the other.

Xuan Du stopped in his tracks, with some hesitation on his face.

Ever since the Dashang Xuanniao wailed and lost his luck that day, the master let him go out and walk around.

So he obeyed his master's instructions, bid farewell to his master, Jinyintong'er and the green bull with flat horns, dressed lightly, and left Daluo Mountain.

But where should we go?

Master didn't tell him, so he wandered around by himself.

He is very familiar with Nanfang Buzhou, and he is also very familiar with the human race, because he is the first disciple of the human religion, and he is also the first generation of human ancestors fabricated by the saint Nu Wa.

No one knows the human race better than him.

He witnessed with his own eyes that the human race moved from that small valley in ancient times to all directions step by step, leaving their footprints in every corner of the prehistoric continent!
Even now, he often walks in the territory of the human race.

Wearing a green cloth robe and a pair of hemp shoes, he has walked through countless springs, summers, autumns and winters.

It also accompanied him from the wild cave to the high city and the big port, from drinking blood to the bell, from the Three Emperors and Five Emperors to the Great Shang Dynasty...

Now, he has to keep going.

After leaving Daluo Mountain, he planned to go to Naqi Mountain to have a look, but on the way, he heard that there was some trouble in the lower reaches of the Huai River, so he turned to the southeast, wanting to see the excitement.

But along the way, his brows became more and more wrinkled.

The world has changed.

Cause and effect are chaotic, and there are countless obstacles.

The God of Incense and Fire acted recklessly, forcing the human race to sacrifice and offer sacrifices by various means, and regarded the human race as a tool for tempering fragrant copper.

Most of the officials, wealthy households, and witches in the city gate became the helpers of the god of incense and fire.

One side gathers money, and the other gathers fragrant copper.

Each takes what he needs, win-win cooperation.

But for ordinary people, life is getting harder and harder.

"Western Sect has gone too far." Xuandu muttered to himself, "After we go back this time, we must discuss it with Master."

After all, he continued to move forward.

Going forward is Linhuan Pass.

It is said that the water god there was chosen by the people themselves.

This is very interesting.

Xuandu walked towards Linhuan Pass full of expectations.

It is said to be a pass, but in fact there is no danger at all here, it is just a settlement built when the wasteland was reclaimed.

Except for that city gate, there are neatly reclaimed farmland in all directions, and the rice planted in it is almost ready for harvest.

Xuandu stopped to watch, but saw densely packed rice growing in every piece of farmland.

A plant, the root system is connected, the branches and leaves depend on each other.

There is no end in sight.

Moreover, the ears of rice hanging from almost every rice stalk are extremely full and huge.

The ears of rice are heavy, cyan, and vivid.

"How come the rice here is so dense?"

A trace of puzzlement flashed in Xuandu's eyes.

Although rice is not grown in most places in Nanbuzhou, he knows that in places with abundant water systems near the south, people mostly eat rice.

However, rice loves water and is not drought-tolerant. After planting, it is necessary to ensure that there is enough water in the field, otherwise it will be easily sunburned to death.

Therefore, if you want to grow rice, even in a land with abundant water system, you have to look at the face of the water god.

Even so, rice is a crop that is far more delicate than hemp, millet, millet, wheat, and bean.

Insects, birds, weeds, etc. all pose a fatal threat to rice.

As a human ancestor who has run through the history of the human race, Xuandu is very familiar with these things, and even "taken" the rice ears of the Emperor Shennong in Huoyun Cave.

The rice grown from Shennong's ears is so big and plump, it is called Jiahe.

But at this moment, he saw Jiahe everywhere!
Looking at the distance again, the shore of the surging Huai River is filled with mist.

Tall wooden utensils are standing on the shore, and the round things like wheels are slowly turning, rolling up water waves from the bottom of the water, and leading them into the canal on the shore along the waterway.

Xuan Du looked at the wooden utensil carefully, with a look of novelty in his eyes.

In the end, he determined that this thing needs neither supernatural powers nor Taoism.

Instead, it rotates with the water flow, continuously introducing the Huai River water into the ditch.

As long as the Huai water is not dry, the appliance can work day and night.

This is much more reliable than the Water God!
Xuandu was very interested, so he asked some common people in the farmland to inquire.

These people are guarding the rice fields to prevent birds and beasts from spoiling the rice, so they have time to chat with him.

From the mouths of these common people, he learned a name - Wen Zhong Shangxian.

It was this Wen Zhong Shangxian who asked the people to cut down trees, drag them to the river, and make those huge wooden utensils called "waterwheels".

And teach the people to build channels, dig mud from the riverbed and riverside tidal flats, use it to fertilize the fields, improve farm tools, and optimize rice seeds...

Therefore, although the people near Linhuanguan did not worship the water god, the fields would never lack water, and the crops were lush, and it seemed that an unprecedented bumper harvest was coming.

After hearing this, Xuandu was amazed in his heart, and also a little curious about that Wen Zhong Shangxian.

An old man who couldn't hide his smile and showed his hard teeth enthusiastically introduced: "If you want to find a Shangxian, you can definitely meet him in the small forest in the south of the city at this time."

Xuan Du thanked the old man, and soon came to the small forest in the south of the city.

There is a thatched cottage in the woods, and hundreds of children sit cross-legged under the shade of the trees, leaving a big circle in the middle.

Surrounded by these children, a young man with a broad forehead, thick eyebrows and big eyes was talking about something.

The children listened carefully one by one, but Xuandu, who thought he knew everything about the human race, found that he didn't quite understand.

What are bacteria?
Why does water have to be boiled before drinking?
What is immunity?
……

Before he could understand these questions, he listened to the young man say: "After talking about hygiene knowledge, let's learn mathematics... I told you before that this mathematics is a tool that can help us understand the world and study tools of the world.

It's not just, it's just simple addition, subtraction, multiplication and division... Through it we can study space, time, information, machinery, etc..."

As the young man spoke eloquently, the eyes of Xuandu in the distance gradually widened.

He knew that he had come to the right place!
Why is this going to Xiqi!
If it wasn't for the fear of disturbing those children, I'm afraid he couldn't help raising his hand and shouting: "I want to learn mathematics!"
