The primordial era began with the Upper Cave Man.

The distant mountains are green cliffs, like delicate eyebrows, ethereal and dreamlike. Closer up, the colors are vibrant purple and red, lush and verdant, captivating the heart.

Looking up, all I see is an endless expanse of blue water. The sun beats down fiercely, steam rises, and the hazy glow is intoxicating.

Water vapor drifts, passing through thousands of mountains, gathering into water, and falling into the mountains in countless drops.

The mountains are lush and verdant, and travelers hurry into the caves.

There was a person on this mountain, perched atop the peak to greet the rain, his body steaming with countless wisps of water vapor, resembling a fairy in robes and feathers.

Suddenly, another person darted through the mountains, starting from the mountainside and reaching the large flat area at the summit.

He single-handedly pushed aside the rain curtain and found the person on the mountaintop: "Chieftain, the rain is so heavy, let's go back and take shelter."

He stood trembling in the rain, as if a ferocious beast lurked beneath the curtain of rain.

Luo Zu, standing in front of him, was trembling, and the flesh on his face was twitching incessantly.

"Such a perilous situation is perfect for tempering one's spirit. You should go back now. I'll return when I can't take it anymore." Luo Zu waved his hand, managing a weak smile.

Ironhead, who came to see him, scratched his head, unsure whether to listen to Luo Zu or stay and keep him company.

But this rain was truly terrifying, far more terrifying than the last time he faced the unicorn.

Luo Zu still urged him to go back first: "Go back first."

His tone became much sterner, and the stubborn kid could only nod and agree in the end.

Then he quickly retreated, scrambling and crawling as if someone was chasing him with a knife.

After watching him leave, Luo Zu continued to fight the heavy rain alone.

The reason why this rain has such a terrifying and awe-inspiring power is because the rainwater is taken from that vast "lake".

This "lake" is the footprint left by the "Dragon God" in Luo Zu's records when he passed by. After the water accumulated, it formed such a large lake and sea, its vastness comparable to the sum of the four oceans in Luo Zu's previous life.

A trace of the "God of Longbo" remains in this footprint.

This mere trace of aura would likely be enough to intimidate even an immortal.

As for a "false immortal" like Luo Zu, the mere rain formed by the lake after being soaked by this trace of aura was enough to make him tremble and his legs go weak.

The terror it caused was beyond description; even Luo Zu's fear was insufficient to describe it. If one were to be exposed to it for a long time, one would probably be "scared to death."

The ancestor of mankind was scared to death by a rainstorm...

If it really works, Luo Zu will be remembered for all time.

He could command wind and rain in the world within the gourd, killing the most outstanding figures among the small human race with a wave of his hand, but in the prehistoric world, he was still a nobody, a piece of trash that could be killed by even a fart from "Longbo God".

After persisting for about an hour, Luo Zu finally got up unsteadily.

He rubbed his cheeks to relax his jaw, which had been aching from clenching his teeth for so long.

Then he quickly descended the mountain and ran away without stopping for even a second.

As long as one doesn't enter this rain, the oppressive aura of "Longbo God" within it can be greatly reduced.

At this moment, the mountains were completely silent. As the saying goes, "Birds have vanished from a thousand mountains, and human tracks have disappeared from ten thousand paths." The mountains, which were already ruled by the terrifying upright apes, were now devoid of any animals. Even the dense forests were withered, as if the rain had been in vain, and the rainwater had failed to make them thrive.

As Luo Zu passed through a familiar forest, he casually reached into a tree hole and pulled out a short-legged, plump dove with a full head of white markings.

It was three feet tall and had a wingspan of eight feet. Luo Zu had been coveting its large wings for a long time, but this fellow was quite wary of the "caveman," so Luo Zu couldn't catch it.

They often hide themselves in dense forests, using the thick trees as cover.

Even Luo Zu's arrows had a hard time hitting it.

When it had just started raining heavily, Luo Zu rushed up the mountain and saw it hiding in this forest. Sure enough, Luo Zu caught it.

After catching the large spotted dove, Luo Zu didn't even count how many legs it had. He simply held it to his forehead to shield himself from the wind and rain, and then ran towards the tribe's cave.

"Chieftain, Chieftain." At this moment, some clansmen were trembling and waiting for him at the cave entrance.

Luo Zu ran into the cave, first brushed off the rainwater, then threw the large dove on the ground and told someone to roast it, leaving it only one wing, and the rest of the meat to be divided among everyone.

Afterwards, Luo Zu went back to his room to meditate and rest.

This spiritual gain was substantial, as if I had been washed clean, removing most of the filth and impurities.

Luo Zu activated the Three Souls and Seven Spirits Yin Spirit Technique, causing his own soul and spirit to solidify within the room. Then, through the perspective of his physical body, he could see that his Yin Spirit was more solid than before, and the range that his divine sense could probe had also expanded by three feet.

Luo Zu had received such benefits twice before, which he discovered by chance, leading to his current method of tempering the spirit, which made the spirit progress faster than before.

However, due to this vigorous spiritual advancement, Luo Zu's physical body will need to be maintained for an additional half month.

After training his spirit like this last time, he chewed 300 jin of meat every day for a full eighteen days.

Fortunately, due to his cultivation of Qi into spirit, his digestive ability was extremely strong. The essence and residue of the meat were completely digested, so he didn't have to spend all day in the toilet.

His digestive system is now like a furnace; it can easily digest anything except soil, stone, and steel, as well as plants and meat, without producing any waste.

Luo Zu was worried that if things continued this way, his anus might degenerate and disappear.

Wouldn't that turn you into a mythical creature that only eats but never gets anything out of you...?

However, it's okay if the anus is gone, then you won't have to worry about hemorrhoids.

Is this a case of turning misfortune into blessing?

By observing the Yin spirit with the physical body and eyes, and by scanning the physical body with the Yin spirit's consciousness, the two complement each other, one can know some of the mistakes or omissions in one's own cultivation.

Then make improvements, which is something Luo Zu does every day.

One must be cautious in one's spiritual practice, especially a pioneer like him. He must be extra careful, for one wrong step can lead him astray, and it will be difficult to correct it later.

Moreover, at this time, Houtu Niangniang was still the ancestral witch of the Wu tribe and had not yet undergone reincarnation. When people died, they died and perhaps nothing was left. Their souls and bodies returned to heaven and earth, or they might become vengeful spirits, continuing to live tremblingly on the earth, and then return to heaven and earth when their lifespan ended.

As for the ghost that dies becoming a demon, and the demon that dies becoming...

Whether Luo Zu possessed these things is unclear.

After wandering outside for a while, the Yin spirit returned to the physical body, making the body, whose seven souls had been taken away by the Yin spirit, more rosy and fuller.

On the path of cultivation, before attaining enlightenment, the physical body must be preserved intact. If the physical body is destroyed, the soul will also be incomplete. If only the soul remains, it will be difficult to survive on this land, and it will be impossible to strengthen the soul, let alone increase cultivation.

Therefore, according to Luo Zu's deduction, one must at least cultivate a primordial spirit so that the soul has a place to reside, so that one can abandon the physical body.

That's a story for another time; Luo Zu is now just a primordial ant.

After the rain, just as Luo Zu was about to enjoy his roasted dove wings, the all-seeing eye that had been keeping a close eye on the red-haired monster suddenly came to report.
