The primordial era began with the Upper Cave Man.

The day of revenge always comes quickly. During the once-every-three-day food supply, Mu suddenly unleashed his power, knocked down the person delivering the food, stripped off his clothes, transformed his body and bones according to his physique, and then left the dungeon without a sound.

He knew he was no match for the tribal chief, so he decided to bide his time and hide in the mountains. He was most familiar with the mountains, and once he entered them, even if the entire tribe came looking for him, they would not be able to find him.

During Mu's absence, a minor incident occurred. Money can be tempting, and Luo Zu's generosity by the campfire attracted the attention of a group of desperados, which led to a small conflict. Ultimately, Luo Zu successfully completed part of the human elimination work.

After eliminating these people, Luo Zu quietly left, this time without leaving any "remains".

He had been here for so long, yet not even a single night had passed in the primordial wilderness.

The night was still long, and Luo Zu continued to immerse himself in the world within the pot.

At this moment, people finally stopped lingering on the "sacred mountain," the mountain where Luo Zu's first remains were located, and prepared to begin their exploration.

Furthermore, three of the Five Great Masters of the World have arrived to observe the martial arts masterpieces of this "ancient" era master. How could this not ignite such a surge of passion?

"It is the way of Heaven." One of the Five Greats, Plum Blossom Sword Master, holding a long sword made of natural jade, stood on the tree canopy with his feet on the green leaves and said lightly.

"This senior is truly remarkable." Eight Palms Lianjue, also one of the Five Greats, exclaimed in admiration.

"Ha, we've been exploring the Heavenly Dao for so long, yet we've never seen that inexplicable Heavenly Dao. Don't actually believe that guy's nonsense," another expert, Lian Shan Jue Dao, said indignantly.

The guy he was talking about was Wu Jue, one of the Five Greats. He was always talking nonsense, saying that the path to martial arts lies in the Heavenly Dao, and only by merging with the Heavenly Dao can one enter the Great Zhou Body and achieve even greater success.

Some people believe this claim, while others do not, and the debate has never stopped.

Now, this debate may finally come to an end.

The corpse on this mountain, shrouded in a cloud of blood, will surely provide them with the answer.

"This power is like the might of heaven, subtly inspiring people to immerse themselves in it and become one with it. It is influencing our will, haven't you noticed?" A voice suddenly came from down the mountain.

A burly and extraordinary figure appeared beside them, moving so lightly that none of the three noticed him.

"Martial Arts Mastery!"

This is none other than the martial arts master who is arguably poised to become the leader of the Five Greats.

"Have you found the way forward?" Plum Blossom Sword Master stared intently at him.

"He is the way forward." Wu Jue pointed with his hand.

After that night, news of the Five Greats' forceful incursion into the Holy Mountain spread throughout the world.

At the same time, the news that they had seen the way forward also shook the world.

The remains of the ancestors on the sacred mountain were also given a name—the Golden Body of the God of War!

Furthermore, after the Five Greats stormed the mountain, the Martial God's golden body disappeared without a trace, leading people to suspect that it had been stolen by the Five Greats.

However, the Five Masters repeatedly stated that this matter had nothing to do with them.

As the legend of the God of War's golden body gradually spread, Luo Zu got up because it was dawn.

Even though he could summon wind and rain and stir up the world within his teapot, he still has to brush his teeth and wash his face himself.

Although one can expel dust and metabolic waste from the body by breathing after refining Qi into spirit, Luo Zu still insists on brushing his teeth and washing his face every day.

In addition, he actively promoted sanitation work among the "Peak Cavemen".

The first step was to prevent people from urinating and defecating anywhere. A small room was specially carved out in the cave, with a drainage ditch leading to it, so that everyone could relieve themselves. They could also pile up manure, which would be more conducive to irrigating the fields at the entrance of the cave.

After the simple stone latrine was built, Luo Zu, relying on his prestige accumulated over the years, forced everyone to use the toilet together and never urinate or defecate anywhere again, except when hunting. If they were in a cave, they had to abide by this rule.

Next is brushing teeth and washing face. Luo Zu can't promote it yet, since he's still testing suitable brushes for brushing teeth. As for washing face, you can just use mountain spring water.

Of course, promoting hygiene and health is not a big deal. At least in the primitive times when people were struggling to make ends meet, it was not necessary to encourage it. However, urinating and defecating indiscriminately is unsightly and can easily lead to diseases and affect the living environment, so it must be prohibited.

"Good morning, Boss Luo Zu." Huowa grinned, showing his big yellow teeth and breathing out his ancient breath as he approached.

"You mated with Ah Si again," Luo Zu said casually, glancing at his face.

Huowa's smile froze awkwardly on his face, even his bald head was stiff: "No way... Boss told me not to mate, so I absolutely won't mate."

Luo Zu remained noncommittal: "You'll be three hundred years old in another year."

The "Upper Cave Man" reached adulthood at the age of eighteen, at which point all of his organs matured. Over the next five hundred years, his physical condition would continue to improve. Around the age of five hundred, his bodily functions would begin to decline, and finally, around the age of one thousand, his vitality would be completely exhausted, and he would die.

This conclusion was reached by Luo Zu after communicating with the elders who once lived in the settlement.

Of course, the "Peak Caveman" has only reproduced to the fourth generation so far, and the future situation is still uncertain. Whether they will extend their lifespan or gradually lose their former spirituality remains to be seen.

As for Luo Zu's recent ban on Huowa's mating, the main reason is that this fellow has recently become aroused and has been constantly seeking mates, which has led to a significant decline in his physical condition and has greatly hindered his cultivation of Qi-refining techniques.

To refine essence into qi, one must have "essence" to refine. Of course, this "essence" is not the same as that essence, but rather essence and qi.

"You've left behind quite a few descendants by now, haven't you?" Luo Zu suddenly changed the subject.

"A-Si gave birth to twenty-eight for me, A-Niu gave birth to twenty-six for me, and Ah-Hei gave birth to thirty-two for me, but only eighteen survived." Huowa said sullenly.

Although the first generation of humans in the prehistoric era had extremely high physical qualities, the environment in the prehistoric world was so harsh that the survival rate of infants in the "Mountain Cave" settlement was always low.

Very few survive to adulthood. Even though Huowa was considered strong in the settlement, and the women he mates with are no less physically capable than men, the survival rate is still very low.

It was only after Luo Zu took over the settlement in recent years that he "introduced" a lot of knowledge about childbirth, which greatly reduced the infant mortality rate.

"Practice the Qi Refining Technique I taught you diligently, so that we can protect our people and give birth to stronger children." Luo Zu patted his shoulder.

"Boss, how about you teach us this today?" As Huowa spoke, he raised his hands, clenched them into fists, and threw several hook punches into the air.

"This is martial arts."

This is the martial arts skill that Luo Zu displayed during the last hunt. The hunting team members all witnessed it and were eager to learn it.

All I can say is that the people in this prehistoric world are ambitious.
