"Auther, do you recall when I first explained to you that harnessing fire is the key to civilization?" Rico asked, his voice steady and commanding.

"Yes, I remember," Auther replied, his throat dry with anticipation.

"Excellent," Rico nodded, "Now, I will demonstrate to you the true power of fire." As he spoke, Rico’s expression was serious, and his eyes were filled with a hint of sadness, as if he knew that what he was about to show Auther would change his life forever. The mood was somber and reflective, as Auther watches Rico, feeling a sense of awe and respect.

As soon as Rico spoke, a bolt of lightning descended from the heavens, illuminating the landscape in an otherworldly glow. The bolt struck the earth, setting ablaze the trees, turning them into pillars of coal in an instant. And with that spark, a raging inferno was born, devouring everything in its path with a hunger that could not be sated.

The fire spread rapidly, consuming the forest with a ferocity that was both majestic and terrifying. The sleeping trees and animals were jolted awake by the heat and light, and they fled in all directions, seeking refuge from the destruction that was consuming their home. The many beasts of the land, from majestic stags to timid rodents, left their habitats in droves, forming a panicked tide of creatures seeking escape from the burning land. The scene was one of incredible beauty, but also of terrible destruction. The fire was awe-inspiring and mind-blowing, a force of nature that both created and destroyed in the same instant.

Auther stood in awe as he witnessed the scene before him, the fierce inferno consuming everything in its path. It was the first time he had ever laid eyes on such fire, and he couldn't help but feel a sense of wonder and amazement.

"This is the future for humanity, a flame that even the most powerful beasts can only flee from," Auther exclaimed, his eyes bright with reverence and understanding.

"Yes, this flame is the key to humanity's path to civilization. Only by mastering fire can we drive away the beasts and conquer hunger," Rico's voice was calm, yet powerful, as he spoke. His words struck Auther deeply, resonating with a sense of holiness and destiny. The mood was one of awe and reverence, as Auther gazed upon the fire, feeling a sense of connection to something greater than himself.

Rico raised his hand and muttered a few words. As if in response, the dark sky was suddenly filled with thick, ominous clouds. The rain began to pour down in heavy droplets, dousing the forest fire that he had ignited. The flames were quickly extinguished, and the once-destroyed forest began to reform, as if the rain itself contained the source of life. The sight was majestic and awe-inspiring, as the once-devastated land was reborn in an instant, thanks to Rico’s power. The fire and the rain, both forces of nature, played out in front of Auther, showcasing the balance and the power of nature. The scene was one of great detail and complexity, as the process of destruction and rebirth was happening before Auther's eyes.

Auther looked at all this with a mix of envy and admiration. As he spent more time with Rico, he couldn't help but be drawn to the immense power that Rico wielded, the power of a god. He wanted that power for himself, to be able to make the world bend to his will, just like Gaia. But deep inside Auther knew that it would be a dangerous path. He knew that the power Rico held came with great responsibility and a heavy weight of morality. "I will teach humanity to control the flame and start a new order of things," Auther nodded, trying to keep a straight face and hide his inner turmoil.

"Very well. I choose you, the new king of humanity. I hope you will not let me down and lead humanity out of the age of ignorance. Instead of the path of carnage." Rico smiled, with a hint of sadness in his eyes, as if he could see through Auther's thoughts.

"I shall work hard to live up to your expectations." Auther knelt on the dirt respectfully, trying to show his loyalty and respect.

"Before we part. I want to give you something." Rico waved his hand gently and took out a long sword and a ball of blue flame, which was on top of a torch-like object. The sword was intricately crafted, with symbols of fire etched on the blade, and the blue flame was mesmerizing, illuminating the darkness. Auther knew that these gifts came with great responsibility and the potential for great destruction. He accepted them with a solemn expression, promising to use them wisely and for the betterment of humanity.

The blue flame that was on top of the torch-like object was also something Rico created using Origin. It was called the "Flame of Creation," and it had the ability to create any form of flame and control its intensity. It was a powerful tool for harnessing fire, and Rico had chosen Auther to be its keeper.

The power of "Origin" can be applied to living beings to enhance and strengthen the body. This energy is incredibly powerful and has a wide range of magical effects that are yet to be fully explored and understood by Rico. What is currently known about the use of Origin is just the tip of the iceberg.

One of the ways in which Origin can be harnessed is through the enhancement of weapons. For example, a long sword strengthened by Origin energy is incredibly sharp and can cut through almost anything. In an age where technology is not yet advanced, such a weapon would be considered indestructible by many.

Another application of Origin is in the creation of fire. Rico, was able to use Origin to create a flame that never goes out. This is reminiscent of the story of Prometheus in Western mythology, who stole fire from the gods and gave it to humanity.

"This sword and flame are gifts for you, Auther. Use them wisely and lead humanity towards a brighter future." Rico said, his voice filled with solemnity.

Auther took the sword and flame with shaking hands. He knew that with these gifts, he would have immense power and responsibility. He vowed to use them for the betterment of humanity, and not for his own personal gain.

Although Rico has taught Auther how to create fire, the true potential of this power extends far beyond just starting a flame. With this kind of fire, it is possible to demonstrate its incredible strength and versatility to others, potentially revolutionizing the way people think about and use fire.

Auther, being aware of the potential power of these weapons, expressed his excitement and nervousness at the prospect of wielding such a powerful tool. "The armaments of God.", he said, full of anticipation.

"Not only this," Rico replied with a smile. He then proceeded to unravel the Origin energy that had been surrounding him, shaping it into a ball and incorporating it into Auther's body. This process had a profound effect on Auther.

In the world of Eden Plain, the principle of natural selection holds true, where only the strongest survive and are able to claim their place at the top of the hierarchy. However, with the acquisition of this new power, Auther has the potential to transcend the limitations of the natural order and ascend to a level of strength and influence beyond what was previously thought possible. This newfound power brings with it a great responsibility, as the consequences of his actions could have a profound impact on the society and culture of Eden Plain, potentially shaping a new era of progress and development. It is crucial that Auther approaches this power with wisdom, humility, and a sense of purpose, rather than using it for personal gain or to further his own ambition.

Therefore, Auther's knowledge and intellect alone are not enough to change the course of civilization. In order to truly have an impact, he must also possess a dominant source of power. This is why Rico had to merge Origin into Auther's body.

The power of Origin can enhance Auther's physical abilities, giving him a physique that is beyond that of ordinary people. With the sword reinforced by the Origin, he would be able to skillfully defeat even large numbers of opponents with ease.

After the Origin entered Auther's body, it brought about drastic changes to his physical appearance. His body became robust, with his aura becoming more resilient and confident. He grew to an impressive 210 cm tall, with completely developed and defined muscles. His physical capabilities were enhanced to an inhuman level, allowing him to perform feats that would be impossible for a normal human.

Auther took the sword and the fire in his hands, feeling the weight and power of the objects. He couldn't help but marvel at the level of technology and magic that Rico possessed.

"This sword and fire are truly powerful, but with great power comes great responsibility." Auther said, looking at Rico with a solemn expression. "I will use these gifts to lead humanity to a brighter future, but I will also make sure to use them wisely and for the greater good."

Rico nodded in approval. "I trust in your abilities, Auther. You have the potential to be a great leader and bring humanity to new heights. Remember, the power of Origin is not just for destruction, but also for creation. Use it to build a better world, not just to conquer."

Auther nodded, understanding the gravity of Rico's words. He sheathed the sword and held the fire in his hand, feeling a sense of determination and purpose. He knew that the path ahead would be difficult, but with the power of Origin, he would be able to lead humanity to a new era of prosperity and civilization.

With the long sword in hand and the torch burning brightly, Auther set out on his journey with a sense of determination and purpose. He knew that the path ahead would be filled with challenges, but he was determined to see it through. He could feel the weight of the sword in his hand and the warmth of the flame on his face. It was as if they were guiding him, reminding him of the power that he held and the destiny that lay before him.

As he traveled through the land, he encountered many tribes who were reluctant to join his cause. But Auther was not easily deterred. He used his knowledge and the power of the flame to defeat their strongest warriors and show them the strength of his own.

With each victory, Auther's reputation grew and more and more tribes came to join his Empire. The people were amazed by the power of the flame and began to see Auther as a savior, a leader who would guide them to a brighter future.

As the Empire grew, Auther's ambition also grew. He began to envision a world where humanity would be the dominant force, where they would no longer be at the mercy of the beasts and the elements. He would be the one to lead them to this new world, this new order.

With the power of the flame and the knowledge that Rico had imparted to him, Auther set out to conquer the world and create an Empire that would last for all time.
