The primordial era began with the Upper Cave Man.

Luo Zu had not expected such a commotion, which far exceeded his estimate of "thousand feet" of blood energy.

Unfortunately, he chose a desolate and uninhabited place, so the possibility of a small group of humans climbing over the mountains to come and worship him was almost nonexistent.

Of course, what Luo Zu did was not to make the small human race worship him; he was just experimenting and trying out the wonders of the Qi and Blood Breathing Method.

See if it can be applied to oneself.

However, this sudden outburst of blood and qi seemed to have been a bit too forceful, and ninety percent of the blood in his body was expelled.

Therefore, his appearance at this moment was emaciated, with his skin and flesh clinging to his bones, like a dried corpse that had been dried for many years on a mountaintop.

"Good heavens, I've gone too far." Luo Zu's jaw twitched a few times, and then the life force in his body gradually died out.

At this moment, he had no time to retract the blood he had spat out, and could only feel the slow death of this avatar.

His internal organs had lost their function due to the gushing of blood, and his brain had also shut down. The only reason he could still think at this moment was because he was possessed by a spirit.

Finally, one minute and fifty-six seconds later, Luo Zu was pronounced dead after all resuscitation efforts failed, at the age of only seven hours and twenty-six minutes.

He died young.

Luo Zu did not expect this result, but he was unwilling to give up, so he conducted a second experiment.

He chose a desolate mountain wilderness again, and once again brought his avatar's physical condition to the optimal state for a small human, before circulating his qi and blood breathing technique.

This time, he limited the outflow of qi and blood, only raising "hundred feet" of qi and blood, which was the "thousand feet" of qi and blood he had envisioned.

It covered the sky, which was more than 300 meters high.

Luo Zu still felt that his clone was completely drained of energy and blood.

Once this vital energy leaves the body, it is difficult to retrieve; it can only be replenished through subsequent food and breathing techniques.

After this relatively successful experiment, Luo Zu quickly recorded the various physical data he obtained from the test.

Luo Zu then continued his experiments combining the blood and martial arts of small human races.

By unleashing qi and blood within the body, and by allowing qi and blood to permeate the skin and strengthen the muscles, bones, and skin, one can unleash three to five times the original power, and the destructive force is far greater than an attack from bare fists and legs.

Furthermore, the blood and qi can adhere to the weapon and extend outwards, resulting in greater attack power.

Just like Luo Zu at this moment, he no longer allowed his blood and qi to spur out freely within a range of 500 meters, but instead gathered it into one place, transforming it into a bloody, viscous, hundred-foot-long sword.

Then, with all his might, he pierced the soil and rocks on the mountaintop beneath his feet with the sword.

Rumble!

The blood sword pierced through the mountain as easily as cutting through tofu, and then it exploded within the mountain.

In an instant, the towering "thousand-foot" mountain was neatly divided into pieces by blood lines, just like cutting tofu. Each piece of the mountain was smooth and clean, as if it could be used as a mirror.

Rumble!

The mountain collapsed, cascading down the mountain ridge, stirring up billowing dust and causing birds and beasts to flee in panic.

Luo Zu's clone closed its eyes, its life force dissipating, and the remaining dried corpse lay quietly in the ruins of the mountain.

He was still not satisfied with the result, and the experiment continued.

This was repeated seven times in one day.

He finally stopped the experiment after using his breathing technique and martial arts to kill 1,008 monsters and carefully recorded all the experimental data.

"Unfortunately, it is too barbaric and cruel. It is a good method to perish together with others, but it is not a good method for cultivation."

Luo Zu had already made his judgment.

Although it's not exactly a good thing, it can be used to create a Heavenly Demon Disintegration Technique...

They're risking their lives in the wilderness; there's nothing shameful about doing something like that.

As for whether it has a future, Luo Zu cannot make a judgment at the moment. After all, his vision has reached its limit, and he is still exploring his own path of cultivation.

In addition, he had another idea, which was to try to accelerate his "time" by using the world within the pot and manipulating the forces of nature.

He dared not do such a thing on the primordial land; although his lifespan was long, it would be gone if he accelerated it a few times.

Cells divide and divide again, which accelerates aging.

Moreover, the means to accelerate cell division and thought speed can only be implemented within the world of the pot.

With this idea in mind, Luo Zu decided to possess his clone in the world within the pot every night when he was resting.

"In this way, it can be considered a form of life extension," Luo Zu said with a self-deprecating laugh.

This is indeed a kind of unconventional life extension, since the cells are accelerating the division of clones, not the original cells themselves, while his thinking is also accelerated, so time is also accelerated.

However, after the first day of the attempt, Luo Zu's consciousness was still somewhat uncomfortable when he separated from the world within the pot.

First, there is a period of mental emptiness, followed by a rapid recovery as the mind is nourished by its own brain, but then a sense of emptiness follows.

"We need to find a way to solve this problem," Luo Zu said, his face pale, after passing the emptiness.

If this happens dozens more times, he might really start to feel empty.

This emptiness cannot be described as fatigue, but rather as a blank mind, a strange feeling of wanting to be a part of the universe.

After Luo Zu repeatedly entered and exited the world within the pot to accelerate his thinking, another ten years passed for the small human race.

Ten years is nothing, but the small human race has gained three more tribes, bringing the total to three thousand.

The reproduction rate is really fast. After the previous batch of infants grows up, they join the reproduction army. Each person gives birth to one child per year. Over time, the population has increased from more than two hundred to three thousand in just twenty years.

Luo Zu did not interfere at all during this process.

However, for so many people, the vast world within the pot is still just a drop in the ocean.

But Luo Zu discovered that there were even greater differences in the "genes" between the various tribal groups.

The environment is truly changing them.

After the changes occurred, Luo Zu did not interfere. He simply accelerated his thinking and observed the human race.

In addition, he recently began keeping the live animals he hunted in captivity.

Then remove their body tissues and put them into the world within the pot.

In this way, a group of creatures from the primordial world were created in the world within the pot, but unfortunately they were all just wild beasts that Luo Zu came into contact with.

In addition to putting the body parts of docile wild beasts that he had specially selected into the world within the pot, Luo Zu also put the body parts of ferocious beasts that he had hunted into it.

Upon careful calculation, twenty-seven types have now been incorporated. As for those ferocious beasts that can breathe fire and spew wind blades, Luo Zu did not collect them into the world within the gourd, otherwise it would cause some unnecessary trouble or even affect Luo Zu's experiment, which would be bad.

As for the wild animals kept in the caves, Luo Zu even held a special meeting for the entire settlement to discuss them.

After some discussion, everyone finally agreed to Luo Zu's proposal—that the elderly and children in the settlement would be responsible for them.
