From the two suns in the universe. Lu Yun began to think carefully.

This matter is basically a myth and legend level in this world, but in Lu Yun's opinion, it is completely different.

To put it simply, those two suns are most likely meteorites, and if the world really changes dramatically because of those two suns, it may be the production of some kind of material brought by those two meteorites.

Combined with the fact that the two meteorites can be called the sun, they are certainly not small, but such a large volume has not caused the extinction of the species......

You know, the current consensus on Earth is that the Cretaceous mass extinction was caused by an asteroid about ten kilometers directly.

An asteroid of ten kilometers will cause a mass extinction of species on the earth, and the two suns in this cultivation realm should not be much smaller than that, otherwise they will either be wiped out in the atmosphere or can only cause local damage.

But this is not quite the same as what Bai Meizi said.

Because if an asteroid of this size hits the planet, it is impossible for people to see it and draw it.

The mass extinction of species, will it give you time to paint?

There's definitely something wrong with that. If we extrapolate from another angle, the two asteroids are very likely to be large in size but small in mass, burning in the atmosphere to produce a huge light comparable to the sun, but the impact power is far less than imagined.

"So the composition of these two suns ......" Lu Yun's eyes suddenly lit up: "Generally speaking, the composition of asteroids in the universe is relatively complex, and there is everything, but the volume is large, the impact power is small, and it causes the large-scale evolution of the world's species in a short period of time, then it should be a gaseous liquid or pseudo-solid asteroid." ”

Lu Yun's speculation is reasonable.

No matter how you look at those two suns, they shouldn't be stones or metal, otherwise they can be regarded as the size of the sun, and it will be difficult for the planet to slow down for millions of years on the ground.

But according to this white eyebrow, it is only two thousand years......

It's definitely not too powerful.

Coupled with the large changes in species, it means that there must be some kind of material on these two meteorites.

It is likely that the material was rubbed away during the atmospheric phase, emitting a huge bright light, and then slammed into the ground to cause massive damage without breaking the bones.

Later, because of the material of these two meteorites, the creatures of this cultivation realm began to undergo great changes, for example, the ancient human race began to produce spiritual intelligence, and their size became larger, and the animals in this world also became larger......

So let's take it according to the knowledge of the earth......

Lu Yun: "So this heaven and earth aura is a gas that can make the body shape of a species change dramatically?" This situation on the earth is mainly in the Cretaceous dinosaur era, when the earth's creatures were generally relatively large, so the aura of this heaven and earth is actually a kind of oxygen? Isotopes of oxygen? There are 28 isotopes of oxygen found on the earth, so this heaven and earth aura may be oxygen-29? ”

Lu Yun was frightened by the results of his analysis.

If the aura of this heaven and earth is really oxygen 29, then don't say it, many mysteries can be solved......

Of course, this kind of thing involves the atomic level, and Lu Yun definitely can't verify it now.

But this did not delay his whimsy: "Assuming that this thing is really oxygen-29, then that is to say, the two meteorites of the ancient flood brought a huge amount of oxygen, and then there was a great oxidation event in this world, and the species changed dramatically because of the increase in the proportion of oxygen content......"

"And a lot of things in this world are acting with oxygen-29, so they show a lot of special states."

"And the array diagram is actually a kind of pattern structure that can trigger the oxygen-29 reaction......"

"Then in the future, my research direction can be closer to this aspect, hahahahahahahaha!"

Lu Yun can be said to be a soul flying out of the sky, and it was not easy to finally take back his thoughts.

At this time, Bai Meizi continued to preach on the stage: "After the ancient flood era, it is the Stone Age. In the Stone Age, the size of the human race has obviously changed dramatically, and our current height is about the same, but in this Stone Age, the human race has always been oppressed by the people, it is no exaggeration to say that almost all the strange beasts in the world feed on the human race, and the number of the entire human race is only ten million. ”

Lu Yun hurriedly took notes - if this was really the Great Oxidation Era, it would not be easy for the human race to survive.

You must know that the dragonflies of the Cretaceous period were more than a meter long, and it was reasonable for a wolf to be only five meters long at that time, right?

In the face of such a giant beast, it is indeed a fate for the human race not to be extinct.

Bai Meizi continued: "This state has lasted for more than 100,000 years, and seeing that the human race is about to become extinct, at this time, in our human race, the first three immortal emperors have appeared!" They are Zhenyang Immortal Emperor, Red Pupil Immortal Venerable, and Jiuyao Star Monarch! The three Immortal Emperors led the human race to lay a large territory, killing ninety percent of the big beasts in the entire territory that were in trouble, and in the end, only some of the big beasts escaped and entered the south of the domain realm to be spared. ”

"After this incident, this is the respite of our human race, and those big demon beasts also want to regain their territory from beginning to end, so the grudge between the human race and the demon beasts has been formed since tens of thousands of years ago."

Lu Yun hurriedly took a note and wrote down the keywords: Zhenyang Immortal Emperor, Red Pupil Immortal Venerable, Jiuyao Xingjun!

This is a good guy at the same level as the Yellow Emperor Yan Emperor in ancient China, and he knows that!

Bai Meizi continued: "After the three Immortal Emperors stabilized the world of the human race, the world officially entered the slave age—which is also what we often call the bloodiest and darkest era. ”

Lu Yun: "??? ”

Huh? What the heck?

The age of slavery is understandable, but the bloodiest and darkest age?

Hurry up and listen.

Bai Meizi said slowly: "The so-called absolute power will inevitably lead to absolute corruption, especially when a person's power and strength have all reached a height unimaginable to ordinary people. The three first generation Immortal Emperors were like that. Thousands of years of life make their tempers more and more moody, and this is the question I raised before, the method of the three immortal emperors to become stronger, there will be absolutely no information outflow, they ruled the entire human society for three thousand years, during that time, the human society was extremely turbulent, all mortals were slaves, all kinds of resources were unearthed for them, and human life was as cheap as grass. And the most terrifying thing is that ordinary mortals can't even see a chance to turn over! ”

Lu Yun: "!! ”

Damn, the human beings of this world can have this kind of insight, and even say that absolute power will inevitably lead to absolute corruption, which is not ordinary!

You know, it's not the same as on Earth.

No matter how centralized power is on the earth, at least the people in power are mortals, and they will die if they are stabbed by a sword.

But it's different here - it's three immortals!

Mortals have no chance to resist if they want to!

Sure enough, Bai Meizi continued: "In those three thousand years, the human race is not without people who want to break free from the rule of the three immortal emperors, but as I said before, when an initial cultivator appears, why should they let ordinary people have the opportunity to cultivate the truth?" The final result was that whenever there was anyone in the human race who had only stepped into the realm of cultivation for even a little bit, the three Immortal Emperors would not hesitate to say that he would be killed, or even the entire tribe would be killed! ”
