In the flickering days, thousands of years have passed.

Zixiao Palace was still lecturing, and outside the palace, the temperature in the entire immortal world had dropped a lot.

Many plants and animals accustomed to the warm environment began to go extinct on a large scale.

But many more creatures have stubbornly adapted.

On the one hand, Zhang Zifan burned the floor heating, and the temperature in the yard did not drop too much.

On the other hand, it is because the energy film isolates the air circulation between the world of the small courtyard and the outside world.

Oxygen molecules are not yet able to penetrate the energy membrane, and water vapor is even more not.

Therefore, in the immortal world, it is not as heavy as Chen Guo's moisture.

Without the magical attack of "wet and cold", the winter days in Jiangnan would not be so difficult to spend.

But the fairy world was still more or less affected.

Zhang Zifan's small courtyard is very large, in fact, it should be regarded as a large compound.

Relying on him to burn firewood alone is still somewhat inadequate.

Many places in the fairy world were covered with ice and snow, and everything withered.

Take Nanzhan Buzhou as an example.

The plants of Nanzhan Buzhou evolved from the terrestrial branch of cyanobacteria, and then differentiated into multiple biological groups, basically following the evolutionary route of terrestrial organisms.

Among these primitive plants, ferns are the most abundant.

Ferns have no seeds, reproduce with spores, and can only adapt to warm climates.

When the Xiaoice period came, the ferns were hit hard and died extensively.

Gymnosperms such as pines and cypresses, which are relatively more adapted to cold climates, quickly fill the void left by the retreat of ferns.

This change has led to a change in the population of animals that feed on plants.

Gymnosperms are perennial woody plants, mostly tall trees with uniaxial branches, few shrubs, and sparse vines.

This has led to food shortages for many animals adapted to feed on low ferns.

For example, the duck-necked boy of Li Zhuang has been having a headache over the years because of the reduction of raw materials for Li Zhuang's white meat.

Pigs, or Tibetan Tuanzi Daisen, a type of obese dinosaur identified as pigs, have seen widespread deaths.

Judging from the trend, in the future, the reduction of pork production has become inevitable.

On the contrary, the duck-necked dragon group to which the duck-necked boy belongs, is thriving day by day.

As the name suggests, a duck-necked dinosaur is a dinosaur with a particularly slender neck.

Because the long neck is more able to reach the leaves of tall trees such as pines and cypresses, the duck-necked dragon family has an advantage in this round of species evolution.

Such changes are taking place in different ways not only in the southern Zhanbu continent, but also in several other continents.

But only in one place is the exception.

That's Buzhou Mountain.

Buzhou Mountain is a blessed place of the true God.

At the time of the Eternal Night, the fire of heaven shone on this place.

And when the catastrophe of the ice river came, Buzhou Mountain was the place where the earth fire began, which can be described as a deep blessing.

To put it simply, Zhang Zifan's floor heating stove is set up under Buzhou Mountain.

Separated by a thick layer of soil, the temperature of the firewood makes the vegetation around Buzhou Mountain lush and green.

Not only are the primitive ferns still flourishing and firmly occupying the ecological niche, but all kinds of cute dinosaurs can also maintain their original lifestyle.

It seems to be a huge Jurassic Park up and down the mountain, and all kinds of creatures that should have been ruthlessly eliminated by nature are living happily.

It's just that the top of the mountain is now open a hole, like a volcanic crater, and terrifying hot gases escape from here.

Near the entrance of the cave, there are no people or animals.

But the Zixiao Palace, which was located directly above Buzhou Mountain, was blessed, and the warm air flow slowly rose, making the entire thirty-three days away as warm as spring.

In Zixiao Palace, a group of disciples listened to the "Panxue" with relish.

They are in a warm palace, listening to lectures every day, eating fairy beans, and living a leisurely life.

It seems that the great changes that are quietly taking place around the world have nothing to do with this small classroom.

The so-called fairy bean, it is said that Hongjun Daozu said that it is a divine object that the true god has mercy on everyone and has been rewarded.

As long as you eat a small pill, you can go without food for several months, and the injury and illness are all effective, and the effect is remarkable.

On the same day, Zhang Zifan ordered Hongjun to open the altar to teach, and he acquiesced in his identity as a Taoist ancestor.

But Zhang Zifan felt that he was going to start a sect and establish an ancestor, and the equipment was really shabby, he only had a few tattered pieces, and he regarded them as treasures, which was really embarrassing for himself.

So Zhang Zifan rewarded many magic weapons and handed them to Hongjun.

These magic weapons are all innate spirit treasures, and they are very powerful.

Among them is a handful of aged millet.

This aged millet is the dregs saved in the Baihemen barn over the years, and it is distributed to the outer disciples to raise chickens and ducks.

This kind of thing, even the fist product of Hakuhemen, the meat with Hakutsuru, is disdainful of eating.

Since Zhang Zifan no longer raised chickens, he still had a lot of millet scum in his hands, so he took a handful and handed it to Hongjun.

These millet slags, for Hongjun, are tantamount to rolling boulders.

If he had been 200,000 years ago, he might have been stoned to death by these boulders.

However, today's Hongjun is no longer Wuxia Ameng.

is just a millet scum, and he can't help him anymore!

At the very least, you have to have peanuts.

Hongjun refined the boulder-like millet slag into the size of a bean and named it Xiandou.

The taste of this fairy bean is still the taste of millet dregs, mixed with a stale musty smell that can't be dissipated.

However, a small immortal bean contains energy that is a whole millet slag.

Therefore, as a food, the taste of immortal beans is really not very good, but in terms of the value of cultivating immortals, this is too great.

After all, the immortals in this fairy world are going to eat.

And it's a bit like a Saiyan, who is strong and has a lot of food, and when you're hungry, you get weak.

Therefore, this fairy bean, which can fill the stomach and heal wounds, has many wonderful uses.

Whether it's a retreat or a battle with the enemy, fairy beans are extremely useful things.

Hongjun didn't hide his selfishness, and distributed some of the fairy beans to everyone, looking unstingy and wealthy.

For everyone, Hongjun Dao Ancestor casually took out some things, which was such a treasure, and it showed the essence of Zixiao Palace and the True Temple behind Zixiao Palace, and he didn't dare to have half a contempt in his heart.

Especially the two Styx Dao people and the Tibetan Tuanzi Dao people, they had their own chances, one got the innate milk sea, and the other got the innate spiritual spring.

It is impossible to say that there is no sense of self-satisfaction, and even give birth to ideas similar to "maybe I can surpass Hongjun later, and I am the ancestor of the Dao".

But when they saw the fairy bean, they realized their shallowness, so they settled down and studied "Panxue" seriously.
