The primordial era began with the Upper Cave Man.

After recording the changes in his body and noting down his Four-Nine Mystic Arts Transformation, Luo Zu summoned the anxious crowd waiting outside the cave.

After all, the changes he had just caused were quite significant, even dramatic, and nothing like this had ever happened before.

"Chieftain, are you alright?" Tie Touwa asked with concern as he entered first.

"It's nothing," Luo Zu replied lightly.

Everyone breathed a sigh of relief. Then they heard Luo Zu say that he would teach them a new cultivation method and promote it to the entire clan. Children aged three to eighteen would also have to practice this method.

"The Four-Nine Mysterious Technique?" Iron-Headed Boy held the simple book, looked at the witchcraft text on it, and even read it aloud.

"Pass it around once first, and then each of you will make a copy later," Luo Zu said.

The copying process also helps them deepen their impression. Although everyone is quick-witted and has a super strong memory, they can remember everything after reading it once. However, sometimes what comes to mind is different from what they see when they hold it in their hands.

In addition, if you have any insights, you can write them down in a book. This will help preserve them in your brain. After all, although everyone has a good memory, they receive a lot of information every day, and some memories will be forgotten over time. After all, they are just prehistoric humans, not people with hyperthymesia, and they have not cultivated Yin or Yang gods. Their memories are naturally stored in their brains. Prehistoric humans have lived for so long, so their brains will naturally forget some information instinctively.

Of course, some important things, once remembered by the ancient human race, can be remembered after just one reading and will last a lifetime.

In addition, regarding memory, the process of forgetting memories for the prehistoric human race is also quite lengthy, perhaps because their brain structure differs from that of people in their previous lives.

Of course, Luo Zu wasn't a brain specialist in his previous life, nor did he specifically enlighten every "caveman" in this life, so he can't make a detailed comparison of the differences between the two sides.

No one had any objection to Luo Zu's instructions. The chieftain was right. The chieftain's decision to make me eat excrement was for my own good. This was the consensus of the entire "Peak Caveman" tribe.

"What questions do you have?" After they had read the first transformation's training content, Luo Zu took the initiative to ask.

"Chief, do we recite this incantation when we practice?" Tie Touwa raised his hand.

Luo Zu shook his head: "Just recite it silently in your mind."

His first transformation mantra wasn't some kind of secret incantation, but rather a practice method, written in conjunction with changes in body posture, much like the rhythm of morning gymnastics, one, two, three, four. Of course, he didn't write it in that rhythm; he simply added simplified explanations of some body movements.

The phrase "raise your left hand and right hand together" is a catchy and rhythmic phrase.

However, the subsequent changes are different. This is only a rudimentary first-stage practice method that can improve everyone's practice efficiency.

Starting from the seventh transformation, the practice of the Four-Nine Mysterious Arts will reduce physical movements and begin to enter the stage of mental meditation, where one must sense the spiritual energy in heaven and earth. If one's sensing ability is poor, one can first use one's innate supernatural powers to sense it.

"The first transformation is relatively easy for you, but it will be much more difficult for the children in the tribe. So don't teach them all the postures yet. Take it step by step, and teach them all the postures when they are fourteen years old," Luo Zu instructed.

Everyone responded in unison that they understood. Luo Zu also knew that they understood the importance of things and that they listened to him and would not disobey him. His main concern was that the children might be naughty and peek, which could cause trouble.

"You should copy down the first transformation first, and then distribute it to the others," Luo Zu instructed.

In one day, the first transformation of the Four-Nine Mysterious Technique spread throughout the entire village, including all the clansmen of Tiger Head Village.

During this time, Luo Zu went to the mountain where Qiu Zhi was killed again and plundered Qiu Zhi's flesh and blood.

He was quite lucky; he found three more pieces of flesh, the largest of which weighed ten pounds, and the three pieces together weighed a total of eighteen pounds.

"This knife skill isn't very good; the cuts aren't even either," Luo Zu complained as he picked up the pieces.

In the days that followed, Luo Zu not only supervised the training progress of his clansmen, but also spent his time picking up "trash" all over the mountains and fields.

A year passed in this way. During this time, Luo Zu slowed down the "time acceleration" of the world within the pot, maintaining it at a speed equivalent to thirty to one of the primordial world.

The reason for this is that Luo Zu wanted to focus on studying the Four-Nine Mysterious Technique. Although the main techniques had been written out, the specific practice still needed to be tested and revised repeatedly.

Fortunately, he possessed two supernatural abilities: the ability to create a world within a pot and the ability to manipulate fate. Moreover, he could combine them ingeniously, which saved him from many detours.

Over the past year, Luo Zu has not neglected his cultivation of Qi Refining Techniques. While improving his physical body is important, his cultivation level is even more crucial.

Of course, physical cultivation is also cultivation, and it can even contribute to spiritual practice. However, physical cultivation has not yet caught up with Qi Refining Method.

In addition, Luo Zu must combine the Four-Nine Mysterious Techniques of physical cultivation with the Qi Refining Method, only then can it be considered as cultivating both body and spirit.

Besides, Luo Zu sometimes thought that the changes in the physical body and the advancement of the Qi Refining Technique were not much different. They were both about improving oneself. However, the physical body was about the evolution of flesh and blood, while the Qi Refining Technique would gradually turn to the soul after reaching a high level.

The soul, on the other hand, is more ethereal and exists on a spiritual level, manifesting more in thoughts and spirit.

However, the soul also includes the physical body. After all, the soul originates from the brain, which is also flesh and blood, while the spirit originates from the physical body, including tendons, bones, skin, flesh, internal organs, and the eight extraordinary meridians. Therefore, physical cultivation is also very important for the cultivation of Qi refining techniques.

It's true that Luo Zu had considered things like body cultivation.

However, through his deduction, he concluded that the concept of physical cultivation in novels is not very effective. Cultivation cannot be limited to cultivating the physical body without cultivating the soul, nor can it be limited to cultivating the soul without cultivating the physical body, otherwise it will hinder one's own cultivation.

In particular, what makes a living being a living being is its self-awareness, its knowledge of who it is; only then can it be considered a living being.

Moreover, in Luo Zu's current speculation, the ultimate goal of cultivation should be the summarization and mastery of the laws and principles of the world.

If there is still energy left, then it may be used to create rules and principles.

Before you can grasp the rules, you still need to strengthen yourself. Don't think about physical cultivation or qi refinement; you need to do both.

I want both the body and the soul.

Of course, this is also due to Luo Zu's current limited perspective. He is only a novice who has been practicing on the path of cultivation for "two and a half years". The road ahead is long and he still needs to explore and walk it step by step.

Although he was in a bit of a hurry, he actually had plenty of time.
