In just a few million years, there were only a few animals left, but with the help of the earth's relatively good and rich plant environment, the species richness was quickly restored to the pre-ice age level.

Moreover, it still seems to present a vague situation that goes beyond the pre-ice age.

That's it.

Finally, humans appeared......

From drinking blood to learning how to use fire.

From tearing with bare hands, to learning how to make tools.

From bare pants to shame.

............

As soon as human beings appeared, they began to evolve at a rapid rate.

It was also when he saw that humans appeared here that Mu Chen was interested, and continued to look curiously.

It's just that......

This human history ...... It doesn't seem to be the same as the human history that Mu Chen is familiar with.

"Isn't this the earth?" Looking at the scene in front of him, Mu Chen couldn't help but muttered to himself.

But it's okay, although Mu Chen still has some doubts, Mu Chen feels that this void core will definitely explain all this to himself at the end of the matter.

Otherwise, this Void Core would show itself what it was doing for no reason.

And if you really don't understand the meaning, what's the use?

And when Mu Chen resisted Xingzi and continued to look down, he found that there was something greasy in it.

Originally......

Before his current civilization, there was an advanced civilization on this earth.

And this civilization is not like the world that Muchen is now.

That civilization actually can't cultivate immortals!

It's about advocating something called technology.

"Technology, a word I've never heard of. Looking at the so-called technology of this group of human beings, Mu Chen couldn't help but muttered to himself.

However, with the help of the so-called technology of these pre-human beings, these people are actually living very comfortably.

Because, Mu Chen found that these former humans could use what they called these technologies to create many mysterious tools called steamships that could ride the wind and waves and cross the ocean.

With the help of this tool called a steamer, those former humans were able to make themselves who did not have any spiritual power and did not know any spells very easily cross the ocean and sail in the ocean.

If you want to cross the ocean, in the world that Mu Chen knows, this requires an extremely large amount of spiritual power! This is an ability that only the strong people of the Tribulation Period have!

What's more, these pre-humans also made the tool called an airplane that flew in the sky.

Moreover, the altitude at which this plane can fly is actually tens of thousands of miles in the sky! For this, it is even more difficult for Mu Chen to calm the excitement in his heart, because this flying at a height of tens of thousands of miles is not necessarily possible for the strong people in the Tribulation Period!

In addition to the ships and planes that have subverted Mu Chen's cognition, these former humans have also created many weapons that Mu Chen cannot understand.

These weapons are all disposable, but they can flatten a mountain!

However, because of these weapons called nuclear weapons, these former human beings were divided into nearly 200 camps, and they fought wars without scruples, and those nuclear weapons were also used wildly.

It's just that, in the end, the earth's ecological environment collapsed step by step because of this, and finally the earth ushered in a mass extinction.

The extremely polluted environment made it impossible for the former humans to live, and in the end, they migrated to other planets in a tool called a spaceship, and never returned.

It's just that......

The earth is now in shambles.

There was a miasma of smoke everywhere, and many creatures could not find a suitable environment for their lives, and they began to die one after another.

Eventually, all life on Earth became extinct.

Earth, I thought that these former humans had become like this!

If the history of the earth is compared to a day, then the birth of the earth and the beginning of the Precambrian era are considered to be the early hours of the morning, then there are 24 hours a day.

The birth of a multicellular organism consumes nearly four hours.

And from the emergence of the human race, all the way to the development to ......

In the past, the migration of human races only took up a few minutes!

After tens of billions of years of evolution, the earth finally formed creatures like the former humans who did not care for their homeland at all, and these former humans even wiped out the environment that the earth evolved over hundreds of billions of years in just 10,000 years!

While shocked by the various so-called technological things of the former humans, Mu Chen was also disgusted by the behavior of the former humans who did not care for the earth so much.

The shattered earth, once again, has undergone tens of thousands of years of evolution before it gradually regained its former vitality.

And human beings have appeared again.

However, when humans come out, there are still highly intelligent creatures like the beast race.

In this way, the earth has once again evolved over tens of thousands of years to finally form its current state.

This is the history of the earth.

The image in my mind gradually disappeared, and the rich void air around me came again.

It's just that Mu Chen is thinking.

Why did the Void Core tell itself this?

Is it a reminder to take good care of the earth?

Or should we pay attention to ecological balance?

All kinds of possibilities appeared in Mu Chen's mind, but Mu Chen couldn't pay attention to it.

Because, this void core also did not clearly state what kind of rhyme these pictures wanted to give Mu Chen.

However, Mu Chen had another doubt.

That is, what is the so-called technology of pre-human beings?

Why, after thousands of years of evolution, pre-humans made those terrible tools.

In the current history of Muchen, all races have been purified for tens of thousands of years, but there are no ancient books that record the mysterious technology.

No High Priest has ever figured out what that mysterious technology is.

Even, these various races may now ......

Little did it know that there was once another civilization on this planet......

So, do extraterrestrial civilizations that want to invade the earth master this kind of thing called technology?

Because, these weapons made using technology really amazed Mu Chen.

If that extraterrestrial civilization really mastered this thing called technology, then, judging from the strength of the various races on the earth now, it may be that the earth really has no power to resist at all.

This is also the strong man of the beast clan, hoping to rely on Mu Chen to open the passage to the Forgotten Lands......

It's scary to think about......

Thinking about it, the violent swelling sensation in his body caused severe pain, and it pulled Mu Chen back from his imagination to reality.

And Mu Chen only now knows that these majestic void breaths have actually burrowed into his body one after another at some point, and he is doing other things without assimilating these void breaths in time.

Therefore, the void air is accumulating in his body, and he faintly wants to break his body.

Sensing the abnormality, Mu Chen didn't dare to think about it, and hurriedly assimilated the void breath in his body.

Mu Chen only felt that after these void breaths were assimilated by himself, they all purposefully poured into the faint Void Lord bloodline aura that originally existed in his body, and they actually merged with it, and slowly began to grow the trace of Void Lord bloodline breath in his body.

Feeling the purpose of these void breaths, Mu Chen was of course very excited.

Because the reason why Mu Chen absorbed the void breath emitted by this void core was to strengthen the trace of the Void Lord bloodline breath that was already in his body.

And now, I didn't expect that these Void Breaths were actually the trace of Void Lord bloodline breath that I had taken the initiative to pour into my body, and I didn't need to consume extra spiritual power to pull it by merging with it.

Mu Chen is not in a hurry to be happy now!

Since he doesn't need to use spiritual power to pull these void breaths, then he can also devote himself wholeheartedly to assimilating this void breath, which can undoubtedly greatly improve the efficiency of Mu Chen's cultivation this time.

Watching these void breaths pouring into Mu Chen's body one by one, Song Qi on the side was also tightly guarding Mu Chen's side, closely observing Mu Chen's changes.

Because......

Song Qi never wanted to be separated from Mu Chen again.

However, the void breath contained in this void core was indeed huge, and Mu Chen's absorption was a few days in a row.

And Song Qi has also been guarding Mu Chen's side.

Even when he ate, he watched Mu Chen eat.

Song Qi didn't dare to sleep, but sometimes he couldn't help it and took a slight nap, and then he continued to guard Mu Chen, not daring to take his eyes off at all.

It seems that Song Qi's experience two years ago is still vivid......

From Mu Chen's beginning to absorb the core of the void, to the complete absorption. When Mu Chen opened his eyes again, it was four days later.

As soon as Mu Chen opened his eyes, the first time he didn't feel the changes in himself, but hurriedly searched for Song Qi's figure.

Then, I saw Song Qi with a weak face, sitting in front of Mu Chen and looking at Mu Chen.

When Mu Chen opened his eyes a few seconds later, Song Qi reacted and hurriedly wanted to stand up, "Brother Mu......"

But......

When Song Qi wanted to stand up, he found that he didn't have much strength, so he just stood up and fell towards Mu Chen in front of him.

"Fool!

Haven't you slept in the past few days!"

Looking at Song Qi, who fell into his arms with a weak face, Mu Chen couldn't help but blame.

hugged Song Qi, Mu Chen also hurriedly carried Song Qi into the house and placed Song Qi on the bed.

"I ...... It's okay. ”

Looking at Mu Chen, who was hugging himself on the bed, followed by being busy, Song Qi also smiled at Mu Chen, and said weakly.

"Don't say it!

Looking at Song Qi, who was smiling at him, Mu Chen's heart was also slightly warm, but he said it harshly.

Looking at the angry Mu Chen, Song Qi finally couldn't hold it anymore, and lay on the bed and fell asleep.

"This silly girl ......"

Looking at Song Qi who was sleeping heavily on the bed, Mu Chen also shook his head a little helplessly.

"I'm just absorbing a void core, really, why bother holding on!"

............

A day later, at dusk.

"Hmm......"

Song Qi, who had rested, finally opened her eyes slowly.

"Awake?" Looking at Song Qi who opened his eyes, Mu Chen also hurriedly stepped forward, carefully helped Song Qi up, and leaned against the wallboard.

"Brother Shepherd......"

"Okay, needless to say, I'll go get you some hot soup. ”

Helping Song Qi up, Mu Chen also touched Song Qi's forehead lovingly, turned around and walked out.

Soon, a strong smell of herbs came from outside the door.

Mu Chen's figure also walked in with him, and there was also an extra porcelain bowl full of medicinal soup in his hand.
