Primordial Era: I am a treasure trove, full of magical treasures.

Xuanbao sat cross-legged atop Shouyang Mountain, his body radiating neither dazzling divine light nor earth-shattering phenomena, but rather a profound aura that subtly resonated with the mountains and rivers, and with the faint yet tenacious flame of civilization of the billions of humans below. He did not immediately begin his sermon, but instead sprinkled his divine sense, like the gentlest rain, across the vast territory below.

The centennial period has arrived.

The area surrounding Shouyang Mountain is no longer the scene of just a campfire belonging to the Lieshan tribe. As far as the eye can see, the foothills, plains, and valleys are densely packed with people from all directions, numbering in the tens of millions. They live in simple caves or sit in the open, their rough animal hides mixed with simple hemp clothing, and the totems and decorations of different tribes gleam in the sunlight. The crowd is bustling, yet they spontaneously maintain a solemn order. At the forefront of the crowd are the three ancestors of humanity, whose auras are the most enduring and whose eyes gleam with the most serene wisdom: Youchao, Ziyi, and Suiren. Although humanity is no longer what it once was, three ancestors have still emerged, and their strength has been elevated to the level of Great Luo Golden Immortal through merit. However, how much power they can unleash remains unknown.

Following them were tens of thousands of leaders from various powerful tribes, such as Lieshan, whose strength ranged from Golden Immortal to Profound Immortal.

Xuanbao's gaze swept over the faces filled with expectation, trepidation, and thirst for knowledge. His voice rang out calmly and clearly, requiring no magical enhancement, yet naturally reaching the hearts of every human present, and even those billions of miles away who were devoted to this path:

"The hundred-year period has arrived. Humans, please listen attentively to what I have to say."

The clamor subsided completely, leaving only the whistling mountain wind. Countless eyes were focused on that seemingly ordinary figure atop the mountain.

"Father God!"

With the appearance of Xuanbao, the three ancestors of the human race, who were the most powerful among the original 129,600 people, were the first to recognize Xuanbao's identity.

"Father God! It's Father God!" Suirenshi, the first of the three ancestors, knelt down in the most devout posture, his eyes filled with tears, and bowed in reverence.

"It's the Father God!" At the summit of Shouyang Mountain, among the first generation of humans who had witnessed the Xuanbao at their birth, someone was so moved that tears welled up in their eyes, and they cried out in disbelief. The voice was not loud, but it was like a pebble thrown into a calm lake, stirring up ripples in the silence. Immediately afterwards, more and more of the first generation of humans recognized that unique aura engraved deep in their blood and soul—gentle and kind.

In the area where the Lieshan tribe was located, the Lieshan chief was shocked. He looked at the group of people who had eaten roasted meat with Xuanbao. His eyes were filled with disbelief. The immortal who had eaten roasted meat with them back then was actually the father god of his human race.

It's no wonder that no one in the Lieshan tribe recognized them. The human race has been multiplying for tens of thousands of years and has reproduced for countless generations. The Lieshan tribe is only a tribe that was born in the last few hundred years. Although there are several Father Gods among the human race, no one dared to think of this, so naturally no one recognized them.

In an instant, like the wind rustling through wheat fields, the resounding cry of "Father God" echoed throughout the area surrounding Shouyang Mountain. Tens of millions of humans knelt in unison, a testament to their deepest bloodline and soul-deep reverence. Their awe deepened, and their anticipation burned even brighter. They finally understood why immortals had preached to humanity—it was the Father God's return, to personally pave the way for their future!

Xuanbao felt the overwhelming faith and excitement below, and felt quite embarrassed. He was probably going against the natural order, but since things had come to this, he could only grit his teeth and continue.

"Get up." Xuanbao's voice carried a calming power. "I am here today to fulfill our previous promise and to pave a viable path for the future of the human race."

Xuanbao said no more and went straight to the point. He sat cross-legged on the mountaintop, his figure seemingly merging with Shouyang Mountain. His voice was not loud, but it was like the imperial decree of the Great Dao, clearly imprinted in everyone's heart, and even transcended space, faintly echoing in the sky above all human settlements.

"In the primordial world, all races thrived. Some relied on innate supernatural powers, some on powerful bloodlines, and some on innate inheritances. The human race, born after birth, was weak when its form was first formed. How could it establish itself? How could it prosper? How could it achieve immortality?"

The three questions, each hitting the core of the matter, left all of humanity holding their breath.

"There are three things to rely on: first, 'unyielding will'; second, 'wisdom to pass on the torch'; and third, 'ability to be inclusive and open-minded'. These three things reside in your character and are manifested in your actions over the past century—recording and passing on traditions, observing and understanding, and cultivating your mind and character are all practices of these three things."

"However, possessing only willpower and wisdom, without the means to transform them into practical power, protect the people, and develop methods for survival, is ultimately just a mirage, easily broken by wind and rain, and vanished by time. Therefore, today I transmit to you the 'Martial Path Cave Heaven Scripture,' a fundamental method of cultivation tailored to your individual physical characteristics, current circumstances, and future potential!"

"The *Martial Path Cave Heaven Scripture* uses 'Martial Arts' as its sharp edge, tempering the body and qi, engaging in battles, protecting oneself and others, and opening up living space; it uses 'Cave Heaven' as its root, tapping into one's own potential, communicating with the spiritual energy of heaven and earth, nurturing spiritual wisdom, and carrying the torch of civilization. Martial Arts and Cave Heaven complement each other, forming the two wings for the self-strengthening of the human race!"

Next, Xuanbao began to explain the specific cultivation realms and methods. He did not speak of profound and obscure mystical principles, but rather combined the most familiar life practices, hunting experiences, and natural observations of the human race, describing them in the most simple and vivid language.

"The first realm is the Blood-Moving Realm. You hunt ferocious beasts and consume their flesh and blood, and you will feel your strength increase. This is the most primitive form of 'Blood-Moving.' However, it is scattered and disordered, and you can only exert one or two tenths of your strength." Xuanbao stretched out his hand and gestured, and the blood and qi of the strongest warrior below involuntarily began to rise slightly. Under the guidance of Xuanbao's Daoist rhyme, a faint red light appeared on his body surface, slowly circulating along a specific route. "The Blood-Moving Realm requires the system to condense the blood and qi throughout the body, making it as easy to control as an extension of one's own limbs, and gathering it into a flowing stream. It is divided into four steps: 'Condensing Blood and Qi,' 'Tempering Muscles and Bones,' 'Unblocking the Hundred Meridians,' and 'Blood and Qi Smoke.' To enter the threshold, there is no need to seek external help. Daily labor, hunting and fighting, and even the 'Twelve Basic Body Tempering Techniques' that I will pass on later, combined with sufficient meat and rest, if you persevere, you can step into this realm. At that time, you will be strong enough to lift a cauldron, run like the wind, and no longer fear ordinary wild beasts."

As he spoke, he demonstrated in mid-air. Daoist energy condensed, transforming into a transparent humanoid figure of light and shadow, demonstrating how qi and blood are pumped from the heart, flowing through the limbs and bones, cleansing the muscles, bones, and skin, finally forming a straight, pillar-like, visibly hot, crimson "beacon smoke" above the head. Beside the figure of light and shadow, twelve simple yet profound movements, each embodying the essence of power generation, breathing, and mental focus, were displayed in a loop—the "Twelve Basic Body-Strengthening Forms." These images were deeply imprinted in everyone's minds.

"The second realm is the Cave Heaven Realm. When your Qi and blood are abundant and your spirit is vigorous, you can introspect and sense the Wheel of Life's Origin at the 'Dantian' three inches below your navel. Use your Qi and blood as a hammer and your spirit as a guide to break through the barriers and create a small 'Cave Heaven'." At the Dantian of the transparent figure, a point of light lit up, gradually expanding to form a constantly rotating vortex that emitted a faint glow, slowly absorbing the spiritual light from the surrounding air. "This newly formed grotto-heaven may only be the size of a grain of rice, yet its wondrous uses are boundless. It can automatically absorb the wandering spiritual energy between heaven and earth, nourishing the physical body, making you more energetic and healing injuries faster. It can also store a small amount of vital essence. As your cultivation deepens, you may be able to open more grotto-heavens. The human body is a microcosm; the five internal organs, the four limbs, the bones, and the acupoints throughout the body can all serve as the vessel for grotto-heavens! Heart Fire Grotto-heaven, Liver Wood Grotto-heaven, Spleen Earth Grotto-heaven, Lung Metal Grotto-heaven, Kidney Water Grotto-heaven... If you can open them, each possesses its own wondrous properties, such as increasing endurance, enhancing perception, or strengthening muscles and bones!"

The light and shadow displayed tiny, differently colored openings at the locations of the five internal organs, their energy subtly interconnected and circulating endlessly. The humans below watched, completely mesmerized, never realizing that such a vast world existed within their own bodies!

"The third realm is the Spirit Transformation Realm. Once the cave heaven is stable, a wisp of spiritual intent can be inhabited within it. The pure spiritual energy within the cave heaven, like a stream washing over stubborn rocks, repeatedly cleanses every inch of one's flesh, bones, and internal organs, removing the hidden injuries and impurities accumulated over the years, causing a transformation and sublimation of one's life level." The transparent figure became increasingly crystalline, impurities within its body turning into black energy and being expelled. The entire "person" appeared light and full of spirituality. "At this point, one's ears become sharper, one's eyesight becomes clearer, and one's perception of changes in wind and rain, the withering and flourishing of plants, and the tracks of birds and beasts far surpasses that of ordinary people. Cultivating the first two realms becomes twice as effective with half the effort, and lifespan also increases significantly."

"The fourth realm is the Inscription Realm. This realm reveals the wonders of cultivation and is where your wisdom shines." Xuanbao's tone was encouraging. "After transforming into a spirit, your spiritual awareness will greatly increase. You will form a unique 'cognition' regarding the laws governing the operation of heaven and earth, the flow of your own power, and even the life-or-death struggles in hunting and fighting. By combining this 'cognition' with the spiritual energy of the cave, and inscribing it on your bones, within the walls of the cave, or on the surface of your internal organs, it will become an 'Inscription'."

On the arm bone of the figure in the light and shadow, an ancient "mountain" shape pattern appeared, instantly making the arm's outline seem more substantial; "wind" patterns appeared on the leg bones, and the figure's movement speed suddenly increased; a simple "thunder" pattern appeared in the lungs (obtained from observing thunder and rainstorms), and when the figure opened its mouth, a faint spark of electricity flickered. "Inscriptions are ever-changing and vary from person to person. You can inscribe the 'fierce' pattern, which you learned from observing a tiger pouncing on its prey, to enhance your explosive power; you can inscribe the 'surging' pattern, which you learned from watching a great river flow, to make your blood and energy continuous; you can inscribe the 'burning' pattern, which you learned from drilling wood to make fire, to add a scorching heat to your attacks... This is the key to exploring your own insights and forming the prototype of a unique 'technique'!"

A burst of barely suppressed gasps and excited whispers erupted from the crowd. This was so intuitive! It turned out that spiritual practice could be so closely integrated with one's life experiences, observations, and reflections!

"The Fifth Realm: Array Formation. A single inscription has limited power. However, if multiple complementary inscriptions are arranged according to specific rules and orientations, a more powerful 'array' can be formed." Within the figure's body, several inscriptions lit up, connecting with each other by light, forming a simple defensive array on the chest, and a faint glow immediately appeared on the body's surface. "This array can be placed in key areas of the body, such as a defensive array around the heart, which automatically activates to protect the body in times of crisis; it can be placed on the fists and palms, giving attacks multiple characteristics; those with high cultivation can even temporarily manifest the array to trap and kill enemies. The encirclement formation of tribal cooperative hunting, and the sturdy structure of building houses, can all inspire the way of array formations!"

Xuanbao explained the concepts, cultivation methods, precautions, and connections between the first five realms of the "Martial Path Cave Heaven Scripture" and the current survival practices of the human race, gradually deepening the understanding from the basics.

He particularly emphasized the importance of a solid foundation, the principle of gradual progress, and the warning about matching one's mental cultivation with one's strength: "Cultivation is like building a house; if the foundation is not solid, the tall building will easily collapse. Do not be greedy for speed; every step must be firm. Strength is the tool, and the mind is the hand that holds the tool. With a kind heart, strength can protect one's people and expand one's home; with an evil heart, strength will become a scourge, harming oneself and others. You humans should take the prosperity of your race as your own responsibility, helping and assisting each other. This kind of mindset can also nourish the grotto heaven, making the inscription more in harmony with the Great Dao."

Finally, Xuanbao concluded, "These five realms constitute the foundational chapter of the *Martial Path Cave Heaven Scripture*. They are sufficient to grant individuals of the human race the power to better survive, develop, and resist common threats in the primordial land. Upon mastering all five realms, with diligent and persistent cultivation and the right opportunities, one can attain a level comparable to the 'Celestial Immortal' or even the 'True Immortal' realms of the primordial immortal path. As for the higher realms that follow, involving more profound laws of heaven and earth and fundamental insights, I will continue to pass them on when human civilization advances further, the overall fortune is elevated, and the foundation is even more solid. For now, laying a solid foundation is of paramount importance."

As for why Xuanbao did not pass down the "Martial Path Cave Heaven Scripture," which he had already deduced to the Golden Immortal realm, it was naturally for the sake of balance. He did not want the human race to follow the old path of the Human Witch Clan and become the common enemy of all races.

The Martial Path Cave Heaven Scripture is good, but it requires a lot of blood and sustenance and needs further improvement.

At this point in the sermon, Xuanbao paused for a moment, allowing the humans below to digest the massive amount of information. Tens of millions were immersed in the sound of the Great Dao, many closing their eyes to comprehend it, their blood and qi involuntarily surging slightly. Those with keen spiritual senses even vaguely felt a strange warm current flowing from their dantian below their navels. Lieshan clenched his fists tightly, his eyes flashing with a sharp light. He felt that the bottleneck in his physical body, which had been hindering him for many years, seemed to be loosening. The three ancestors of the human race fell into deep thought. Looking back at this Foundation Establishment method from the perspective of a Great Luo Immortal, they could better appreciate its ingenious design—a relatively low threshold, low resource dependence, high integration with the existing activities of the human race, a clear growth path with enormous potential, and especially its emphasis on "comprehension" and "personalization"—it was practically the best enlightenment method tailor-made for the human race!

Seeing that everyone had begun to digest the information, Xuanbao spoke again, his voice solemn: "The method has been passed down, and the path is under your feet. I will condense the fundamental principles of the 'Martial Path Cave Heaven Scripture,' the detailed cultivation methods and precautions for the five stages of Foundation Establishment, and the 'Twelve Basic Body Tempering Forms' into a legacy mark."

He pointed his fingers like a sword and made a light slash in the void. In an instant, boundless Daoist energy converged, transforming into countless golden specks of light, as fine as dust yet shimmering with the light of wisdom. Like a shower of stars, they rained down on the tens of millions of humans below, while some even traversed space and flew to various human settlements across the primordial land.

The light entered the brows of every human, regardless of gender, age, or whether they were present at the scene. Immediately, the clear and complete contents of the Foundation Establishment chapter of the "Martial Path Cave Heaven Scripture" appeared in their minds, along with the deep imprint of the twelve body-tempering movements, as if they were innate memories.

"This inherited mark can continue with bloodlines. All descendants of my human race, upon reaching a certain level of cultivation or triggering their will, can naturally awaken and acquire the basic content, ensuring the continuity of the inheritance," Xuanbao said slowly. "However, the methods are static, but people are dynamic. How to cultivate, how to combine it with one's own characteristics, and how to integrate cultivation with production, daily life, and tribal development are all things you need to explore, exchange ideas, and summarize on your own. The three ancestors of the human race and the leaders of each tribe, those with virtue and ability, should take on the responsibility of guiding, resolving doubts, and coordinating."

"Remember that humanity must always strive for self-improvement!"

"Father God, have mercy!"

"I will heed the teachings of God the Father!"
