The sun gradually rises.

There are more and more big monsters hovering in the sky.

There are hundreds of them.

They kept landing and lowered the children to the ground one by one.

Then take off again and fly away into the distance.

They have to run for today's incense.

The Great Sage Iron Feather finally appeared.

The huge body carried several children.

The feathers of the Great Sage stood up one by one to protect the children from the wind and cold.

The great sage descended to the ground, and then said softly: "Master Zhang, Master Wang, Master Li, I will go back to Lushan first, and I will pick you up in the afternoon!"

The teenagers were all very polite and bowed one after another: "Thank you, Uncle Tie!"

"Hehe!" Great Sage Tieyu nodded happily, then spread his wings and soared into the sky.

There are more and more ships on the dock.

Gradually a fleet of boats formed on the river.

There are also children who come alone.

They stepped on a sampan and floated here along the current.

If you look carefully, there is always a figure of the Aquatic Tribe escorting them beside them.

At this time, white swallows flew out from the willow city.

Falling into the crowd, each white swallow accurately found its partner.

They were chirping on the shoulders of the teenagers.

A red goose with blood-red feathers also fell into the crowd and rubbed Tao Ming's trouser leg affectionately.

Behind the willow tree, little foxes with snow-white bodies and crystal-like jade hair also walked out of the fox den next to the willow tree.

There are not many of them, only seven or eight.

But if you look carefully, you will find that these white foxes have some thunder marks on their foreheads.

It's just covered up by hair.

These white foxes have their own exclusive seats.

They happily found their very familiar seat under the willow tree.

Then he pulled out a grass-woven abacus from his hair like a magic trick.

Then there are the desks and mats woven from grass, as well as the pens and inks given to them by the people of Liucheng and the books bound in sheepskin.

For people in Liujun, this is a common thing.

The hair of the white fox family under the willow tree in front of Tianzun's throne is like a pocket, which can hold many things.

No one will ask how these foxes do it.

Dou Ziyu and others all took a breath of cold air.

"These white foxes are no longer ordinary auspicious beasts!" Dou Ziyu murmured softly.

Auspicious animals and auspicious birds are inherently auspicious and receive blessings from heaven and earth.

Born to be extraordinary!

Now, going one step further, it is naturally due to the favor of humanity.

Legend has it that in ancient times, when the Holy Emperor ruled the world, there were various similar auspicious objects among the human tribes, coexisting with all the people.

Even dragons, phoenixes and unicorns appear from time to time.

It's a pity that in the world today, there is no such thing as a real dragon, phoenix, or unicorn.

Even ordinary auspiciousness is rare!

Probably, only when the masters from the upper world come down to earth and are bathed in holy virtues can such auspiciousness be revealed!

While thinking this way, the willow tree suddenly started to sway.

Willow branches stretched out to block out the sky and sun, and willow leaves hung down.

The morning breeze brings bursts of fragrance.

At some unknown time, a Taoist priest appeared under the willow tree.

His figure is blurred and his face is erratic.

It seems to be far away in the horizon.

In my ears, a thunderous and uniform voice came: "Hello, Tianzun!"

Tens of thousands of young men and children bowed in unison.

Dou Ziyu and others also quickly followed Jishou and saluted.

Then there was only a cold, indifferent, but infinitely compassionate voice saying: "Hello, classmates!"

"Everyone, sit down!"

Even though it was more than ten miles away, the sound was clearly audible, as if it was right next to my ears.

Tens of thousands of teenagers and children, including children from the demon tribe and water tribe, all sat down in a polite manner.

Strips of willow branches covered their heads.

Every piece of willow leaves lingers with brilliance and leaves a lingering aftertaste.

"Let's learn something interesting today..."

The Taoist under the willow tree gently stretched out his hand.

Streams of light danced from the palm of his hand.

Show the numbers one by one.

0,1,2,3,4,5……

"These are numbers that we have learned and can use in daily life..."

As a result, countless numbers were flying, and an unprecedented symbol was swaying from it.

The concepts of positive numbers and negative numbers were explained in detail.

-

represents a negative number.

As a result, the branches and leaves swayed, and countless streams of light fell.

The children were fascinated by it and seemed to be immersed in it.

Everyone on the periphery only felt their scalps numb and dizzy.

Positive integer, negative integer?

Most people have never even heard of it and cannot accept it.

After the class, even Dou Ziyu's limbs felt a little weak and her mind was heavy.

However, in Dao's heart, he was quite happy.

The concepts of positive numbers and negative numbers have been accepted by him.

Positive is yang, negative is yang, each other is the inside and outside, and each other is the universe.

He took a deep breath and looked under the willow tree in front of him.

The Holy Master, the ‘Big Master’, has gone away indistinctly.

But above the willow tree, there is already an ethereal axis.

Positive and negative numbers suddenly appeared.

And slowly rotated, shaking gently above the tree crown.

This holy tree is even more extraordinary!

Even his figure seemed to become ethereal.

This is the trace of the avenue!

Mathematics Avenue!

Xu Ji rode a big buffalo and appeared quietly on Mount Lu.

The big buffalo walks gently through the grass and through the forest.
