Time flies, time is like an arrow.

In a blink of an eye, it was the end of August, and Xu Ji resumed his old rhythm, except that he changed his classes from one class every three days to one class a week.

It's not that he's procrastinating, it's actually about mathematics and physics on Blue Star. As long as the teacher teaches and the students learn, they can only get extracurricular tutoring and practice questions, which is basically the same.

But in this mythical world, it can no longer be described as magic.

In particular, the curriculum is advanced to high school and gradually deepens into high-end knowledge in the field of mathematics.

Mathematics began to explore finite sets, empty sets, and infinite sets.

The geometric content begins to involve the equations of the surface of space aggregates and circles.

In this mythical world, under the influence of the so-called "Dao", countless magical powers can be directly expanded and subdivided into various Taoisms.

Xu Ji wants to be simple, but he can't be simple.

Because as soon as you start talking about it, all kinds of formulas turn into various changes, turn into magical powers, and derive endless dharma.

To put it bluntly, not only will the students not be able to digest it, they may also be injured due to the excessive loss of their souls.

Together with physics, I started to combine it with mathematics, especially geometry.

Mechanics has also changed beyond recognition!

Moment, strength of planar geometric structure...

This makes the content more and more magical as it goes forward, and the scenes during the lecture become more and more dynamic!

Especially the students are very restless.

If you listen, some people will put it into practice.

Once you put it into practice, it will create a wave!

Forty thousand people were studying, casting, and experimenting at the same time!

All kinds of Taoisms flowed across the river, and countless geometric patterns flew and collided with each other. For a moment, Lushan was agitated, and the magical power flew freely!

At this time, the willow tree will hang down its branches to protect the students and Lu Shan.

To avoid any teaching accidents.

Therefore, Xu Ji could only slow down the pace of his lectures.

Sometimes I have to stop and teach the old god the art of breathing and breathing in the golden elixir stage specially customized by the old god.

In this way, we talked from mid-May to the end of August.

Xu Ji was able to teach about one-tenth of the content of mathematics and physics in the first year of high school.

During this period, he naturally went to Caojun many times for observation.

He also visited various countries in the Central Plains many times.

The situation in Caojun has not changed at all.

From May to now, drought has been the main theme!

The Cao River is cut off, the Tao River is cut off, and the Huanggou is cut off!

All the lakes in the territory have dried up!

For three months, not a single blade of grass grew in Cao County!

What was once fertile land has now turned into a salt-alkali desert.

The surface temperature continues to rise!

Obviously, this is not normal.

It is the joint work of the dozens of drought demons and the fat relics that once wreaked havoc here.

Xu Ji seriously doubted that this was the masterpiece of "Qiongqi" he had ever seen!

Because the situation in various countries in the Central Plains is not as serious as that of Cao State.

Although the demonic locusts are raging, it usually only takes two thousand miles to have a swarm of more than a million demonic locusts active.

Generally speaking, small countries do not have any leftovers.

Only a big country like the Song Dynasty could have one or two fat men.

As for the drought demon?

Xu Ji has found no signs of it appearing elsewhere.

Xu Ji's perception of the cause and effect of heaven and earth also proves this point.

The situation in Caojun shows obvious signs of chiseling.

Someone drove or guided the demonic locusts from other places to Cao County.

This caused serious droughts to occur in dozens of countries, large and small, in the Central Plains.

There are also monster locusts raging, and fat relics are born.

But their situation is much better than Caojun!

There are even places where disasters have never happened at all.

It's been a quiet time.

Especially the areas that Xu Ji once paid attention to.

The country of Zheng, which was shrouded and protected by a jade-like treasure, was just like the old land of China, and nothing happened.

Good weather and no disasters.

This made Xu Ji a little curious, and even wanted to go to Zheng Guo for a while.

But he eventually gave up the idea.

Because he has digested what the old god left in Qinghe.

You know, that jade Ruyi is also the treasure of a certain Taoist ancestor.

It's okay for him to look at it from the periphery. Once he steps into the wishful range, I'm afraid it will immediately trigger the other party's reaction, and some "unpredictable" things will happen.

Xu Ji doesn't have the confidence yet to challenge a Taoist-level figure in a duel.

It would be so embarrassing if someone pushed her to the ground and rubbed her!

Except for paradises like Zheng Guo.

In the Central Plains region, there are also about a dozen small Taoyuans, large and small.

The situation is similar to that of Zheng.

But instead of being sheltered by treasures, he seemed to be protected by heaven and earth.

Just like safe zones, they can provide basic shelter for some civilians in such troubled times.

What’s interesting is that these small peach gardens are basically located in deep mountains and valleys with crisscrossed streams.

Moreover, after Xu Ji's observation, these small peach gardens seem to have some kind of special screening mechanism.

Only those with deep blessings or merit can find, see and enter.

If there is no one to guide others, even if Taoyuan is right in front of them, they will not be able to see it, discover it, or find it.

Get the door without entering.

This made Xu Ji wonder and think of "The Story of Peach Blossom Spring" that he learned when he was in school.

Did the fisherman in Tao Yuanming's novel also wander into such a shelter on Blue Star?

Or……

In fact, what the fisherman entered was an ancient sanctuary in this mythical world?

In short, the longer you stay in this mythical world, the more wonders you discover.

On the last day of August, Xu Ji finished his last class of the year.

Then he said to the 40,000 students who were listening in front of him: "After this class, I will go into retreat. You must not slack off. You will still study hard and practice hard, and you should also take good care of your homeland!"

"Promise!" All the students bowed in unison: "I will obey the teachings of the Heavenly Lord!"

"Next year, I will give you a new assignment!"

Countless people's eyes lit up.

A Taoist heart was beating non-stop.

"Go back!" Xu Ji waved his hand, and the man disappeared from under the willow tree.

The sacred tree swayed and the willow branches drooped.

Starlight is dotted, rising from the countless grass and trees on the top of the mountain.

When everyone turned around, they felt that the top of Mount Lu suddenly became dozens of times larger at this moment.

The feeling of crowding is overwhelming!
