The primordial era began with the Upper Cave Man.

Can you imagine a vine as thick as a human arm with a mouth at its end that spits out a blank pig's head?

The current vampire wisteria is already like this; it could be renamed Pig-faced Vampire Wisteria. If it grows a cow hoof in the future, perhaps it could be renamed Cow-hoofed Pig-faced Vampire Wisteria...

But its appearance is so bizarre, yet it seems so normal in this primordial land.

This is the primordial wilderness, where the creatures are even more bizarre and strange than those ferocious beasts and divine creatures recorded in the Classic of Mountains and Seas. After all, the Classic of Mountains and Seas only records a few hundred kinds of strange beasts, while the vast and boundless land of the primordial wilderness has trillions of strange beasts.

Therefore, Luo Zu was not surprised by the mutation of the vampire wisteria.

He was only surprised by the tenacious vitality of the vampire wisteria; even after being thoroughly investigated, it could still grow back.

But as surprised as he was, it did not stop Luo Zu from eradicating them and burning them to death.

The long-prepared ointment was thrown into the pig-faced vampire vine by the hunting team at the height of midday sun. At this time, the pig-faced vampire vine was withered under the scorching sun. With the ointment as fuel and Luo Zu controlling the fire, the many "caveman" who could directly or indirectly ignite the flames exerted great effort and, under Luo Zu's command, made the flames in the valley rise higher and higher.

The fire started at noon, and the wisteria vines were howling at noon too. They howled for a full three hours. The howling finally stopped near dusk, but the fire was still burning. The oil from these vines has a really strong endurance. After being burned like this, all the wisteria vines will turn into "roasted suckling pigs".

As dusk fell, the fire in the valley gradually subsided, while Luo Zu and his tribesmen had already lit another bonfire nearby, roasting their newly hunted prey and eating it without stopping.

After eating for a while, I looked up and saw that it was already half dark. The sun had already dipped halfway down to the western mountains, and the moon had risen to the east, echoing the gradually brightening stars in the sky.

"Chieftain, we..."

"Go back, come back tomorrow." Luo Zu waved his hand.

Then a group of people started cleaning up the utensils and leftover ingredients for the meal, and then they hurried back.

Although the "Peak Caveman" is now considered the overlord of the surrounding area, the prehistoric night is more dangerous and is a completely different world from the daytime.

Many monsters that were originally dormant will come out at night, especially in this place that has been the site of a "fierce battle". The monsters will come by the smell.

Moreover, the desolate land at night is not only home to living things, but also to inanimate objects.

Imagine some enormous creatures that, after they die, if their consciousness is not completely dead, will become ghosts, carrying their rotting corpses as they roam this land.

During the day, under the scorching sun, they can only hide in dark, gloomy caves, dense forests, or deep underground soil. They may even exhale deathly energy, creating a dense, poisonous mass in a valley, in order to avoid direct sunlight.

Now that there is no underworld or netherworld, they have nowhere to go, and over the millions of years of primordial chaos, the dead on this land must outnumber the living.

The area where the "Cavemen" now live is kept clean by everyone, and the constant lighting from the campfires keeps these inanimate objects away. This is also an experience passed down by the elders to protect their home.

Moreover, now that the ointment has been refined, the campfire can burn all night. At night, only two or three people need to take turns guarding and patrolling to keep the fire from going out.

Now these dead will also be used by Luo Zu. Luo Zu has a good grasp of the amount of ointment. It will end after dusk. Before leaving, Luo Zu has his men throw hundreds of pottery jars into the ruins. These jars are full of rotten prey entrails and blood, enough to attract all the dead to this valley.

At night, Luo Zu did not fall asleep. He left his body and traveled a hundred feet away to the ground outside. Then he used his Thousand-Mile Eye Divine Power to see the situation in the valley.

A few fireflies could be seen in the pitch-black forest. Some of them were probably nocturnal wild animals, while others were scarlet and perhaps some kind of ferocious beast, though it's also possible they were herbivorous predators.

As for that valley, with the help of the moonlight and starlight, Luo Zu was able to see the situation there clearly.

The vampire wisteria had been reduced to charcoal ash, and the entrails of the prey smashed inside were now emitting a foul, fishy stench that had drifted far into the air; even Luo Zu could smell a faint odor.

This is a good thing; Luo Zu's goal has been initially achieved.

While Luo Zu was observing, the sky suddenly "darkened".

Luo Zu didn't need to look up at this moment. He was in Yin God state, with his whole body providing a 360-degree view without any blind spots, so he immediately saw the situation in the sky.

A thick fog enveloped the sky a thousand feet above. Through the perspective of the Yin God, Luo Zu saw shadowy figures within this thick fog, none of which were human.

An eerie, deep mist slowly drifted over Luo Zu's head. It didn't even glance at the "Cavemen" tribe illuminated by the campfire, but instead swam deeper into the mountains. When it passed the valley, it paused briefly, but then continued moving forward without stopping.

Although they disappointed Luo Zu, the night was still long.

Luo Zu's spirit cannot travel for too long at present; it can only leave his body for about an hour before returning to his physical body to be nurtured.

However, a trip can also be quite beneficial for the spirit, as it can deepen its sensitivity to the natural environment. Although one or two trips may not lead to "enlightenment," it can certainly improve its ability to use magic.

This is also why Luo Zu was able to raise so many of his spells to the eighth rank within three years.

After exhaling gently to revive his slightly cold body, Luo Zu put aside his surveillance of the valley and focused his mind on the world within the gourd to continue his research on refining the spirit and returning to emptiness.

Refining the spirit and returning to emptiness is not an easy task. According to Luo Zu's original plan, the spirit should be activated by the five internal organs, and then the spirit should ascend to the Purple Mansion, thereby illuminating the spiritual platform and seeing the body spirit. The brain should be developed to the extreme to build a more stable primordial spirit prototype than the Yin spirit. In this way, one can "calculate" more quickly, have better memory, and stronger thinking ability.

However, after observing the exploratory spirit of the creatures in the world within the pot several times, Luo Zu abandoned this plan and came up with the plan of the Yang God. Yin gives rise to Yang, and Yang is in harmony with the physical body. This allows the Yang God to be more deeply integrated with the physical body, but it can also leave the physical body at any time and travel far away during the day.

Furthermore, it can unleash more potential in the physical body. After all, this body was created by the goddess Nuwa based on the innate physical bodies of many great gods, so how could it only have this much ability now?

He then experimented for another three years, and spent about thirty years in the world within the pot. During these years, Luo Zu slowed down the speed of time within the world within the pot, which also reduced the maladaptive reactions of his physical body when his spirit left the world within the pot. Otherwise, it would be bad to have such a dizzy feeling every day.
