Si Chen returned to the cave and once again entered a state of Cultivation.
For him, improving his strength was the top priority; other matters could be set aside.
The other Human Race members also knew his habits, so aside from occasionally visiting him, no one came to disturb him.
Time flew by.
Another ten years had passed since the birth of the first Acquired Human Race.
In these ten years, the Human Race gained tens of thousands of new Acquired Human Race members, the oldest of whom were already ten years old.
As the number of Acquired Human Race members continuously grew, problems slowly began to emerge.
These Acquired Human Race members were not like the Innate Human Race, who were at the Heavenly Immortal Realm from birth.
The harsh survival environment of the Primordial World was somewhat unfriendly to them.
First, temperature changes between morning and evening, rain, and other weather variations made many newborn infants very uncomfortable.
Some infants even fell ill, but these were early Acquired Human Race members, and their Physique was generally good regardless.
Their mothers often helped them regulate their bodies, which prevented any premature deaths.
However, this also made the Innate Human Race realize that something was wrong.
But no one taught them what to do, and they didn't know how to handle it, so they could only leave it to fate.
Si Chen was aware of the Human Race's situation, but he had no intention of intervening.
Firstly, he didn't want to draw too much attention, as there might be powerful beings watching from above.
Secondly, the current Human Race had no immediate survival problems; after all, their numbers were significant, and Shouyang Mountain was not an unknown place.
There were plenty of Spirit Fruits on the mountain, which also caused the Human Race to lack a sense of impending danger.
Now that problems were emerging, it would naturally trigger everyone's vigilance and thought.
From the moment he learned that infants were falling ill, Si Chen knew that the Three Ancestors would soon appear.
Therefore, he wasn't overly concerned about what was happening to the Human Race.
Ten years passed, and Si Chen's Realm had now broken through to the True Immortal Realm.
The seed had also entered its final stage, but this last bit had not fully completed its Fusion even after more than two years.
Si Chen had no solution for this; he could only wait.
Another year passed in a blink, and an unfortunate event occurred: a newborn infant died.
This caused the entire Human Race to panic, as death was still an unknown concept to them.
After all, it had been less than twenty years in total; most people were at the Heavenly Immortal Realm, and even Mortals would only just be reaching adulthood in twenty years.
Regarding the cause of the infant's death, after ten years, everyone knew what the problem was.
It was the issue of keeping warm, especially during rainy weather, which made people more prone to illness and discomfort.
During this time, the man holding the Creation Whip came to inquire with Si Chen.
Si Chen didn't explicitly say anything, only telling him to observe the changes in the surrounding heaven and earth more closely.
Seeing this, the man could only descend the mountain.
Tonight was another cold and damp night; the little ones who had been playing wildly during the day were now huddled close to the adults.
Only then did they feel a little warmer, interspersed with a few coughs.
"Crack!"
Suddenly, a bolt of lightning streaked across the sky from the clouds, striking a nearby mountaintop.
A large fire instantly ignited, a scene witnessed by everyone.
The man, who had been contemplating how to solve the problem of keeping warm, saw this scene and suddenly recalled the feeling he had when he once passed a burning ancient tree.
His eyes immediately lit up; if they had fire now, wouldn't they no longer have to worry about getting sick?
The more he thought about it, the better the idea seemed, and remembering Si Chen's advice to observe the changes in heaven and earth, he was instantly convinced that this idea was correct.
Thus, he immediately got up and ran towards the nearby mountaintop.
The other Human Race members, seeing this, didn't understand what he was doing; they glanced a few times, then ignored him, merely holding the little ones in their arms a little tighter.
Soon, the man arrived at the place where the fire was burning, and feeling the warmth emanating from his body, a smile immediately appeared on his face.
He approached a burning ancient tree and, without hesitation, punched it.
"Crack!"
The large tree broke in response, and the man, ignoring everything else, picked it up and ran back.
In just a moment, he returned to everyone's presence.
Everyone curiously examined the object the man was carrying, not understanding what he intended to do.
The man ignored them and simply set the large tree down, and intense flames immediately rose several feet high.
The little ones nearby suddenly felt the heat from the flames and instinctively moved closer to the fire.
The other little ones also gathered around, some even reaching their hands into the flames.
However, in just an instant, they were burned and quickly retracted their little chubby hands.
Seeing this, the other little ones also retracted their curious little hands.
Just as the little ones were happy, the flames grew smaller and smaller, and the temperature became lower and lower.
This scene immediately caused the little ones to panic, some even crying out.
Seeing this, the man thought for a moment, then quickly walked towards a nearby tree.
He knocked down the tree with a few loud punches, then, ignoring everything else, dragged it over and placed it on the fire.
"Crackling!"
The sound of burning leaves rang out, and after a brief period of thick smoke, the fire reignited.
"Wah...wah..."
The little ones cheered happily at the sight.
Happy times are always short-lived; the long-brewing heavy rain began to pour down on the earth amidst the thunder.
The raging fire, which had been burning intensely, was extinguished in just a moment by the torrential rain.
This scene caused the smile on the man's face to gradually disappear; looking at the little ones huddled together again, he silently turned and sat down under a tree.
In the following days, all the Innate Human Race members were trying to find a way to solve the problem of keeping warm.
Si Chen naturally saw the situation down the mountain, but he did not intervene.
He knew that the Three Ancestors were about to be born, and he no longer needed to continue playing with birds.
Perhaps it was already destined in the unseen.
Si Chen didn't have to wait long.
After a period of contemplation, three individuals among the Innate Human Race seemed to have an Epiphany, a sudden flash of inspiration.
Among them was the man who had brought the fire.
At this moment, the man was sitting on a piece of deadwood, rapidly rubbing a wooden stick between his hands.
On the other side, under a tree similar to a palm tree, a woman was examining a piece of palm bark in her hand, seemingly lost in a kind of Epiphany, standing there in a daze.
Then her hands began to move, occasionally holding the bark up to her body and gesturing.
Another person was looking up at a bird's nest in a large tree, as if admiring a rare treasure, appearing somewhat captivated.
After a long while, this person lowered his head, looked around, and then walked towards the thatch not far away.
Si Chen, who was Cultivating in the cave, was suddenly startled awake by an invisible force, but this invisible force came and went quickly.
"Could it be... !"
Si Chen seemed to have thought of something, and with anticipation on his face, he got up and walked out of the cave.
As he stepped out of the cave, he saw that the Void Realm outside had already turned golden.
Three golden Profound Lights descended towards the foot of the mountain.
"Heavenly Dao Karma!"
A smile appeared on Si Chen's face; finally, he no longer had to play with birds.
The three masses of profound yellow Karma Golden Clouds once again split into two, with the smaller portion merging into the three individuals' bodies.
The other portion fell respectively onto a burning wooden awl, a garment made of palm bark, and a house constructed of wood and thatch.
"I am Suirenshi!"
"I am Ziyi Shi!"
"I am Youchao Shi!"
Three voices rang out at the foot of Shouyang Mountain.
At the same time, the three Acquired Karma Spirit Treasures, having undergone the baptism of Karma, fell into the hands of the three individuals.
"Boom!"
The aura around the three individuals began to rapidly Ascend.
Peak Heavenly Immortal—True Immortal—Peak True Immortal—Profound Immortal—Peak Profound Immortal—Golden Immortal—Peak Golden Immortal.
Ultimately, the strength of the three individuals settled at the Peak Golden Immortal Realm.
