In the blink of an eye, 800 years have passed.

This is really the most comfortable and quiet cultivation time since Wei Cheng ascended to the Immortal Realm.

For more than 1,000 years, there has been no stability.

Looking back on the past, he couldn't help but feel a lot of emotion.

In the past eight hundred years, he had comprehended and mastered a total of 3,200 immortal runes, thus allowing him to comprehend and master a total of 6,000 immortal realm runes, which was 3,000 more than Yun Li at that time.

Truth be told, that's a bit ridiculously fast.

It took Yun Li thirty million years to master three thousand immortal runes.

But in fact, Wei Cheng and Yun Li are still different.

Because the immortal runes that Wei Cheng selected for enlightenment were the most basic, the most distant, and the immortal runes that the human race had mastered since ancient times.

This kind of basic immortal rune is no longer very useful, and it is more suitable as an auspicious rui.

Not to mention that after five million years, the ecology of the immortal realm has changed, even at this moment, these ancient immortal runes are basically useless, and their power structure has been weakened to more than seventy or eighty percent.

The reason why Wei Cheng wanted to comprehend these ancient immortal runes was not to strengthen himself, but to deduce the change index of the immortal ecology.

Not to mention, it works very well.

Through this kind of reverse inference, he successfully established twelve groups within his Great Zhou Heavenly Illusion Array, each with a time span of 100 million years.

And continue to deduce, evolve, and finally come up with a time span of 1.5 billion years of ecological change model of the fairy world.

And these 1.5 billion years theoretically include the early ecology of the rise of the human race.

To paraphrase the current situation, it is equivalent to the process of the demon immortals who have stepped onto the stage of the fairy world in ignorance and confusion, and have become regional hegemons and global hegemons in the next 1.5 billion years.

Wei Cheng didn't try to make a larger time span again, because he found that there were only so many immortal runes about this period on the Wendao Divine Bell.

Maybe there are more on the first fire, the second fire, but then there is no point, too far.

"There should be one last link left."

Wei Cheng looked at the Great Zhou Heavenly Illusion Array in front of him, which he had rebuilt in the past eight hundred years, and the core was three thousand two hundred ancient immortal realm runes, based on these immortal realm runes, the Great Zhou Heavenly Illusion Array would be able to perfectly reproduce the immortal ecology of the year.

This is more accurate, precise, and perfect than digging up dinosaur fossils and recreating the age of dinosaurs.

Because the fairy rune is the DNA of the fairy world!

As long as it is perfectly understood and mastered, then it can be perfectly reproduced.

This is also an important, core way for the Terran immortals to grasp power.

At this moment, within this Great Zhou Heaven Illusion Array, a miniature immortal realm with an area of 100,000 forbidden pits was being generated.

All kinds of big taboos and small taboos in it are also being generated simultaneously.

Lifelike, no different from the real thing.

And when this miniature immortal realm was completed, Wei Cheng selected one billion immortal cultivators from the natal immortal cultivation realm, as well as a full hundred billion mortals.

Then, Wei Cheng groaned for a few seconds, and then said in a deep voice,

"The Heavenly Demon invaded, and the Dao Fire withered. Three thousand worlds, the human race suffered. ”

"You are the last descendant of the human race in the three thousand worlds, and the Heavenly Demon will invade the immortal cultivation realm where you live in 50,000 years, and then, destroy everything."

"You can choose what to do or you can choose to do nothing."

"The old man is the last emperor of the fairy world, and he has opened up this trial level with supreme supernatural powers, and there are eighteen levels in this trial level, you need to try your best to strengthen yourself and survive."

"Of course, the old man doesn't force it, immortal cultivators can exit the trial level at any time in the first nine levels, and once they die, they won't really die, but they will be eliminated. Return to the realm of cultivating immortals. ”

"Mortals can exit at any time within the first five levels, and at the same time die and be eliminated from the game."

"The trial level of immortal cultivators and mortals will not intersect in the first nine levels, but after the tenth level, you will meet and need to fight together."

"Everything you do in the trial level will trigger different rewards, and cultivating and testing here will make your strength increase by leaps and bounds."

"That's all there is to say, please make a choice!"

After that, Wei Cheng couldn't help but smile, it was a reincarnation.

Although his purpose was different from the original purpose of the Chu Immortals.

Placing this Great Zhou Tian Phantom Array in the Yuan Shen Heaven and Earth, Wei Cheng will leave it alone, and after 50,000 years, the results of the Phantom Array deduction will generate the most detailed and detailed ecological data of the Immortal Realm for him.

Next, Wei Cheng's gaze swept away, and he began to build another Great Zhou Heaven Illusion Array.

So far, he's about to turn into a phantom demon.

Counting the previous two, plus the planned ones that are being built, he will create one large, three, nine small, and a full thirteen Great Zhou Heavenly Illusion Arrays within 50,000 years.

There is no way, in the face of changes in the general trend and ecological changes, trying to reverse and confront it with its own strength is actually the next policy.

After all, no matter how awesome and powerful he is, can he surpass the thirteen Heavenly Emperors of the human race?

That can all cultivate the existence of the ninth Dao body, the ninth immortal spirit armor.

That's already the ceiling.

How many years have people cultivated, hundreds of millions of years, billions of years.

If this is the case, what confidence does he have to think that he is different.

There is only another way.

But this time, Wei Cheng was interrupted, and when he was building the Zhou Tian Illusion Array, his heart suddenly moved, and if he realized it, he heard the anxious call of Qianqiu Immortal Monarch.

However, in the territory of the third fire, the three heavenly emperors and their relatives, and the entire 100,000 people under the core of the core finally turned into Dao fire at this moment.

At this moment, the entire Third Fire Territory was covered by boundless light, and even immortals without Dao Fire could see it with the naked eye.

All the darkness was dispelled, and the entire vast immortal domain was covered with cloud-like Dao fire.

"Wei Xianjun, what happened, why do I have a feeling of great calamity and great sadness?"

Qianqiu Xianjun was still shouting, and even he had begun to cry and couldn't control it.

In fact, it was not only him, but even Wei Cheng and all the Terran immortals who possessed Dao Fire.

This is the last burning of the fire, the last splendor of the Dao fire, this tragedy is indescribable, indescribable, but it can be felt.

Wei Cheng didn't explain anything, although he was also sad in his heart, he still immediately released his Dao Fire, with the help of the last burning of this third fire, resonance, forcibly opened the Dao Fire Vision, he needed more and more information, more and more data.

He wants to see the whole world, he wants to see the whole picture.

He wants to work backwards into the past, he wants to deduce the future.

It's all about these bits and pieces of data.

This time, the burning of the fire lasted for three days and three nights, unprecedented, and it was like returning to the light.

All the immortals were terrified and sad in their hearts, and even the eight hundred wildfires in the second fire, countless heretical immortals sensed that this was a kind of doomsday fire, the light of the sunset, but the sun could rise again, and whether the Dao fire could be rekindled, but they didn't know at all.

Wei Cheng also recorded three days and three nights, and this time he saw more carefully and more distantly through the Dao Fire Vision, and most importantly, it covered a wider area.

The last time he saw the fire, he only looked in the direction of the first fire, but this time, he looked in all directions.

A large amount of data information has been successfully obtained.

In particular, the comparative data of the Heavenly Demon Ecology and the Terran Ecology is simply precious.

Because of this data, he could preliminarily establish the Great Zhou Heavenly Illusion Array on the deduction of the Heavenly Demon Ecology.

Through various experiments in the phantom array, various attempts, to find, to find a way that can delay and weaken the ecology of the heavenly demons.

Even if you can't, you can continue to try and make mistakes for Wei Cheng.

You must know that there are still 100 million years left between this moment and the complete end of the human race, and during this time, he can do a lot of things, maybe he can't save the entire human race, and he can't save other people, but at least, he can let himself live as long as possible.

This is already the last bit of backbone and stubbornness of the human race.
