There was a familiar feeling inside this fire cloud cave.

Zhang Xuan thought about it for a while, and found that the pattern here is very similar to the Wuzhuang Temple.

It's also true, this Fire Cloud Cave was originally the cave of the Red Cloud Ancestor.

"Come, children, come and taste this fire cloud fruit!"

Fu Xi smiled: "And these Zhu Fengguo, taste them, you sit, I'll make tea for you!" ”

"Where do you dare to let your uncle make tea!"

Ao Lingyue hurriedly said, "Just let us juniors!" ”

The smile on Fu Xi's face became brighter and brighter.

This Huoyun Cave suppresses the luck of the human race, there are only three emperors and five emperors, and there are usually no children to serve.

Moreover, the era of several of them is still relatively primitive, and there is a sense of roughness and arrogance.

"I thought you would come a little later, wait a little longer, and the seven black sheep will give birth to a lamb, which will just be stewed for you to eat!" Fu Xi said regretfully.

"Uncle don't be polite! We came to visit my uncle, how could we let my uncle work! ”

Danmei said with a smile, poured tea for Fuxi Zhang Xuan and others to drink, and took the little demon to the kitchen again.

"I've heard of your Monkey King for a long time, and when I see it today, I really show a talent!"

Suiren smiled: "In just a thousand years, there is such a skill, it is really amazing!" ”

"I don't dare to be, it's just some luck!"

Zhang Xuan arched his hand and said, when he came to this Huoyun Cave, there was nothing to do, he really just looked at his uncle Fuxi.

The children were very happy to spin around in the Huoyun Cave, Zhang Yingzhi cried and shouted for the seven-tailed black sheep, and Fu Xi also gave it to her happily.

A table of rice, the Suiren clan and they also ate together.

Although the three emperors and five emperors all had children, for so many years, no relatives came to see them.

This is also, the gentleman's ze, the fifth and beheaded.

Moreover, among their children, few have a long lifespan, and many of them do not know who their ancestors are.

A few people talked and laughed, Zhang Xuan passed through many countries in the Westward Journey to the World.

Because it is necessary to build a perfect world, a basic survey has been made on the population and immortal mages of this immortal and Buddha world.

It was the first time Ao Lingyue heard that Zhang Xuan went to explain the customs and customs of human beings, different from the theory of governing the world of the Three Emperors and Five Emperors, Zhang Xuan was more strategic.

This is not a mortal world, but a world of immortals, so the human race has not changed the world too much.

But even the world of immortals is a world of resource consumption.

Different races consume different resources, and the flow and loss of spiritual energy are also different.

The era with the highest concentration of aura is the age of the lich.

At that time, the aura, heaven and earth gave birth to countless wild monsters, and the number was more than that of humans now.

And because the Wu clan has no divine soul, as long as the body is not bad, it will not die, and there are very many of them.

However, the extremes of things must be reversed, and after the concentration of aura is at the highest point, it will decrease.

This point, in addition to the consumption caused by the increase in the strength of the gods and monsters, is that the aura is consumed in the process of circulation.

Until now, there are monks among human beings, and monks consume spiritual energy.

The ratio of mortals to monks is gradually increasing. This is because the Taoism of the three religions is very prosperous in the world.

But it's just a simple calculation problem, with water entering and draining at the same time.

The water drains faster than the water enters, so it's only a matter of time before this Reiki pool dries up.

All the monks can do is to jump out of this pool before the aura dries up.

Uncle Fu Xi said with a shocked face: "That nephew, when do you estimate that the aura of heaven and earth will be exhausted?" ”

The rest of the people also looked at Zhang Xuan nervously, after all, as immortals with good strength, their lifespan was unlimited.

Now there is a final catastrophe, and death seems to be a foregone conclusion.

"According to my calculations, with the current level of monk proportion, the depletion of spiritual energy will occur after 5.7 billion years, and the concentration of spiritual energy is not enough to support the true immortals, it will be 2.9 billion years later!"

Zhang Xuan said with a smile: "Of course, if the proportion of monks increases during this period, or if there are any calamities in heaven and earth, the depletion of spiritual energy will be advanced, which is not easy to say!" ”

Although the length of time has been pulled to 100 million, it is not too long for the great power, and many of the great power are people who have passed many yuan.

One Huiyuan has 1,399,680,000 years, that is to say, if there are not many Huiyuan, the spiritual energy will be exhausted, and the world will completely enter a state of dead silence.

Even if you want to develop technology, when the sun is about to collapse because of its longevity, it will collapse and destroy itself.

Without the sun, the desolate world will enter a new zero beginning.

"Is everything you say true?"

The flint felt that his mouth was a little dry, and he was a little unconvinced.

Because even the catastrophe of heaven and earth is nothing more than a struggle between species, and it is just who will be the leader.

From the very beginning, the melee of the dragon, phoenix, and unicorn clans, the Dao Demon War, the Lich War, and the God War, all came over little by little.

Now it's a little hard to accept that the world is going to be destroyed!

"Of course, what I said only represents my personal opinion, and the data I collected is not accurate, only a few countries on the westbound road are selected, and the sample is not universal!" Zhang Xuandao.

Zhang Xuan didn't tell anyone much about these things, but when he met the emperors today, he talked to them casually.

After all, they are all excellent politicians, and talking to them about these general trends is also a matter of communication.

However, it is not accurate to say that they are politicians.

They should be said to be tribal leaders, and in their era, it is enough to lead the clansmen to live, far less treacherous and changeable than the society of later generations.

"What can I do? My human race has gone through a lot of hardships and dangers, and I can't imagine that it will be such an ending! ”

Shennong sighed, but tears flowed from his eyes.

"Don't worry, everyone will have to die then, so don't be sad!"

Zhang Xuan said with a smile: "Although the desolate world is in chaos, it is not immortal!" ”

Ao Lingyue and the girls glanced at each other, feeling that what their husband said was too scary, and then looked at the children playing on the side, but they were still carefree, they didn't understand what the catastrophe was.

After leaving the Huoyun Cave, the Three Emperors and the Five Emperors all had sad faces.

"Uncle, let's go back! But don't worry, I'll come back to see you! ”

Zhang Yuan and a few little guys beckoned excitedly.

"Good grandson! Go back slowly! ”

Fu Xi also said with a smile, and then saw Zhang Xuan and the others go away.

Dan Mei said: "King, is the world really depleted of spiritual energy? Will it be destroyed? ”

"Although there will be some discrepancies with what I said, but there is life and death, this is inevitable!"

Zhang Xuan said: "But don't worry too much, with me, I will naturally not let you have an accident!" ”

Back in Huaguo Mountain, Ao Lingyue and a few people put cultivation on the agenda.

Since they were pregnant, they didn't pay much attention to cultivation, and now they know that the danger is not far away, so they naturally don't slack off.

Zhang Xuan took his four children to worship the teacher, but he came to Wuzhuang Guanzhong, first, to let them worship under the Zhenyuanzi Sect to practice, and secondly, to discuss the matter of exploring in the chaos.
