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

Xuanbao sat cross-legged on a cloud, wearing an expression that said, "Let me think about this," but his brows were furrowed like a crumpled rag. After a while, Xuanbao suddenly slapped his forehead, and a look of sudden realization appeared on his face.

What are you thinking? I'm a transmigrator. Isn't it normal to borrow from so many cultivation systems I've seen in my past life? But... the Golden Core Path, Martial Arts, Soul Refining, Body Refining, "these things are all resource-intensive..."

"Martial arts? It's good, isn't it? A punch can split a mountain, a kick can shatter the earth—simple, brutal, and exhilarating. It's certainly very suitable for humans, but compared to those muscle-bound Wu Clan guys, it still pales in comparison," Xuanbao muttered. "But martial arts alone isn't enough; the ceiling is still a bit low. After all, humans have an extra primordial spirit compared to the Wu Clan. If we don't utilize that primordial spirit, wouldn't it be a waste? It's like having great strength but not a sharp mind." Thinking of this, Xuanbao's eyes lit up. "Why not combine martial arts with soul cultivation! Use martial arts to temper the physical body, and cultivate the soul to strengthen the primordial spirit. In this way, I can possess powerful physical strength and also use the power of the primordial spirit to unleash more powerful spells and supernatural abilities. Maybe I can even open up a new direction for cultivation."

Even if not all humans can cultivate it, with such a large population, there will definitely be many geniuses. After all, the original Golden Core method could only be cultivated by a small portion of the human race.

Xuanbao grew increasingly excited as he thought about it, and his previously furrowed brows relaxed. At that moment, a pure white cloud drifted by, as if applauding his ingenious idea. He slapped his thigh, deciding to first find someone to test this envisioned cultivation system; perhaps he could cultivate the first powerful individual who combined martial arts and soul cultivation, ushering in a new era of cultivation for humanity.

Thinking of this, Xuanbao recalled the cultivation system from the novel and anime he'd read in his previous life, specifically the one in "Perfect World," which progressed from Blood Transformation and Cave Heaven to Immortal King and Quasi-Immortal Emperor. "Blood Transformation Realm…that's great!" Xuanbao slapped his thigh. "Humans are currently just a bunch of people with brute strength and surging blood energy, but they only know how to squander it in the most primitive ways! Blood Transformation Realm, as the name suggests, is about controlling the blood energy throughout the body; it's a systematic process of tempering, refining, and utilizing it, unlocking the potential deep within the bloodline. This is practically a tailor-made introductory course for humanity's current state!"

Xuanbao's eyes lit up as he thought about it more and more: "The Cave Heaven Realm... opening up a cave heaven within the body, creating a small world of one's own, absorbing the essence of the outside world to nourish oneself. This idea is excellent! Compared to the myriad races of the primordial world and those innate beings, the innate foundation of individuals is a weakness. Although the human race has gathered the essence and blood of four saints and Xuanbao, a quasi-saint, they are still ultimately acquired beings. The first few generations might be fine this time, but as time goes by, the bloodline will definitely become thinner and thinner. But if everyone can open up a cave heaven within their body, it's like adding nutrition to themselves. Isn't that like carrying a spiritual energy charger and talent amplifier with you? Perfectly making up for the weakness!"

"The Spirit Transformation Realm allows one to reshape their true self and undergo a metamorphosis; the Inscription Realm involves carving runes into bones and inner caves, mastering the rudiments of precious techniques (these precious techniques refer to the innate supernatural abilities of those innate beings); the Array Formation Realm allows one to set up killing arrays within the body, imbuing every gesture with array power... Tsk tsk, each step is interconnected, from exploring oneself to communicating with heaven and earth, and then to mastering the rudiments of laws, progressing layer by layer, with a solid foundation and a bright future. Moreover, it is very flexible. Each person can open different inner caves, carve different runes, and set up different arrays according to their own characteristics and comprehension, fully embodying individualized teaching and customized services, avoiding the embarrassment of mass-producing 'cultivators'."

Xuanbao became increasingly excited as he deduced, dancing and gesturing wildly on the cloud. The surrounding clouds were stirred by the Daoist aura he unconsciously emitted, sometimes transforming into the phantom of a martial arts god fighting against heaven and earth, and sometimes evolving into the wondrous phenomenon of a blessed land swallowing up the starry sea.

"The most crucial thing is compatibility!" He snapped his fingers, a string of sparks flying from his fingertips. "Martial arts cultivate the physical body and will, emphasizing the ultimate application of 'force'; perfect cultivation of grotto-heavens, runes, and laws pursues the exploration of the roots of 'law' and 'the Way.' The two can completely complement each other!"

He already envisioned the future of humanity: a burly man, muscles bulging like dragons, his aura soaring to the heavens. With a roar, ten celestial realms, each radiating a different light, opened behind him with a thunderous boom. Within these realms, runes flickered, and killing formations flickered. He formed a martial arts fist seal with his left hand, drawing upon the power of the runes in his right, and unleashed a punch that possessed both the pure power to shatter stars and the ripples of law capable of annihilating all things. Just imagining it was exhilarating!

"In the future, when humans fight, they'll first open their caves to scare you, then show off their muscles to make you despair. It'll be a combination of physical and magical attacks. Are you scared yet?" Xuanbao chuckled, as if he could already see those arrogant guys who relied on their talents and supernatural abilities being beaten up by the new human cultivators and running away with their heads in their hands.

"However..." After laughing for a while, Xuanbao calmed down and stroked his chin thoughtfully. "Directly copying it won't work either. The Perfect World system has high requirements for resources and the environment. It often requires pure-blooded creatures' blood, rare and precious materials, and the like. Although the current human race has a high starting point, it can't withstand that kind of exploitation. It needs to be simplified, grounded in reality, and in line with the current main theme of the human race: 'hard work and self-reliance'."

He scanned the human race below with his divine sense and saw that they used stones to make tools, animal bones to make weapons, and grass and wood to build houses. They observed the sun, moon and stars and recorded the changes of the four seasons in the most simple way.

"I've got it!" Xuanbao's mind flashed. "In the early stages of cultivation, we don't need to pursue those high-end rare and precious materials. 'Blood Transfer' can be done using one's own blood and qi from ordinary beasts hunted; the initial energy for opening 'Grotto Heaven' can start with the most common spiritual energy of heaven and earth and one's own life essence; the runes inscribed for 'Inscription' can draw upon the rudimentary principles gained from observing all things in nature, or glean the superficial instinctive runes from the beasts hunted; and 'Formation' can be inspired by the teamwork of human group hunting and the arrangement of tribal defenses!"

"Yes! That's it!" Xuanbao's thoughts became clearer with each thought, as if he had unlocked his full potential. "This cultivation method should emphasize 'cost-effectiveness' and 'practice makes perfect' in its early stages. It should allow humans to naturally embark on the path of cultivation amidst their existing production and daily life, their struggle against nature, and their dealings with other races. Furthermore, the results of their cultivation should immediately translate into improved living conditions and enhanced combat power, creating a virtuous cycle!"

"Once they have a solid foundation, are stronger individually, and have a higher level of civilization, they can explore more dangerous areas and obtain better resources. Then we can gradually unlock higher-level cultivation methods that require more resources. This is called sustainable development!" Xuanbao was very satisfied with his "installment payment" style cultivation system design.

"As for the name..." Xuanbao pondered, "The combination of martial arts and grotto-heaven techniques... 'Martial Cave Path'? That sounds awful. 'Perfect Martial Arts'? That sounds a bit like a knock-off. Hmm... This path aims to pave the way forward for humanity, build a strong foundation, and create an infinite future. It emphasizes both the power of physical martial arts in battle and the wonders of grotto-heaven runes. It is tailor-made for humanity... 'Humanity Foundation Building Method'? No, no, no, that's not imposing enough."

His gaze fell upon the majestic Shouyang Mountain below, and he thought of the great god Pangu, and of the mission and potential of the human race born in this primordial world.

"Each of the myriad races of the primordial world has its own path, some possessing innate strength, others divine abilities. Our human race, therefore, should have a path of inclusiveness and relentless self-improvement. Martial arts serve as the spearhead, cleaving through thorns and brambles; the grotto-heavens are the roots, carrying the torch of civilization. Let it be called—'The Martial Path Grotto-Heaven Scripture'! Martial Path symbolizes humanity's arduous journey of overcoming obstacles with strength; Grotto-Heavens represent humanity's wisdom and possibilities in exploring its infinite potential within and expanding its living space without. Scripture signifies that this is a fundamental path that can be inherited and developed!"

With the name and basic framework settled, Xuanbao was in high spirits. He began to meticulously construct in his mind the descriptions of each realm, key points of cultivation, precautions, and how to integrate the "Martial Path Cave Heaven Scripture" with the existing life practices and civilization development of the human race.

"The Blood Transformation Realm is divided into four steps: 'Condensing Qi and Blood,' 'Tempering Muscles and Bones,' 'Unblocking All Meridians,' and 'Qi and Blood Smoke.' Initially, it can be achieved by consuming large amounts of energy-rich beast meat and regularly training and refining. Hmm, we also need to add a set of 'Basic Body Tempering Twelve Forms,' which is simple to learn, highly effective, and suitable for widespread adoption. Lieshan and his group gained strength by eating mutton; that's the most basic form of 'Blood Transformation'!"

"Cave Heaven Realm: Sensing one's own life wheel, using qi, blood, and spirit as guides, one opens an initial cave heaven at the lower dantian (lower dantian). The initial cave heaven may only be the size of a grain of rice, but it can automatically absorb trace amounts of spiritual energy, slowly nourishing the physical body and spirit. As cultivation deepens, one can try to open more cave heavens, and the location is not limited to the lower dantian. The five internal organs—heart, liver, spleen, lungs, and kidneys—correspond to the five elements and can also serve as the place to hold cave heavens, forming 'Five Organs Cave Heavens,' even bones, acupoints... Hmm! This idea is good, the potential is huge!" Xuanbao deduced and recorded at the same time, feeling as if he was designing a super complex nurturing game.

"Spirit Transformation Realm: After the cave heaven is stabilized, the spirit resides there, repeatedly cleansing the body with the spiritual energy of the cave heaven, achieving the first small leap in the level of life, removing hidden injuries and impurities, and enhancing spiritual perception. At this stage, the human race's perception of nature will be greatly enhanced, and it will be easier to comprehend the principles gained through 'observation and experience'."

"Inscription Realm: This involves combining the natural principles one comprehends, the instinctive runes of exotic beasts, and even one's own understanding of martial arts with spiritual energy from one's grotto, engraving them onto one's bones, grotto's walls, or internal organs. Engraving a 'Mountain' pattern might greatly increase strength; engraving a 'Wind' pattern might make one as light as a swallow; engraving a 'Fire' pattern might inflict a burning effect on attacks… This is starting to resemble a 'personalized skill tree'! If Lie Shan were to engrave a 'Fierce' pattern, wouldn't he be even more ferocious in battle?"

"Array Formation: Combines multiple runes according to specific rules to form more complex formations inside or outside the body (initially with the aid of artifacts). For example, combining runes like 'Sturdiness,' 'Rebound,' and 'Spirit Gathering' creates a miniature defensive array beneath the skin; combining runes like 'Sharpness,' 'Armor Penetration,' and 'Speed' on the fist bones creates an offensive array... Isn't this just a humanoid self-propelled array turret? Moreover, the rune combinations can be adjusted temporarily according to the needs of battle, making it extremely tactically flexible!"

Xuanbao's thoughts became increasingly detailed, and he even began to imagine the future development paths of human cultivators: there was the "War God" style, specializing in physical strength, pursuing the ultimate martial arts, and breaking all laws with a single punch; there was the "Mage" style, with numerous cave heavens, complex inscriptions, and expertise in setting up formations and area attacks; there was the "Blood Bull" style, which combined cave heavens with the five internal organs, possessing tenacious vitality and being able to fight and withstand attacks; and there was the "Reconnaissance" style, which engraved inscriptions on their eyes to gain X-ray vision, farsightedness, and dynamic vision...

"Haha, this will greatly enrich the division of labor within the human race! Hunting teams, defense teams, exploration teams, construction teams... all can be optimized according to the focus of cultivation. In addition to exchanging resources, tribes can also exchange different inscription insights and formation combinations! Won't the speed of civilization development take off?" Xuanbao seemed to already see himself preaching on Shouyang Mountain a hundred years later, with people sitting below the stage wearing animal skins and leaves, but with bright eyes and surging blood and qi. That scene would definitely be very interesting.

"Of course, safety must also be considered." Xuanbao calmed down. "Cultivating too quickly can easily lead to an unstable foundation, incorrect inscriptions can cause internal injuries, and opening a grotto-heaven in the wrong location can affect lifespan... Hmm, we need to add detailed warnings and gradual methods to the scriptures. We also need to emphasize the importance of mindset. The stronger the power, the more we need to know how to control it, otherwise it won't be good to become a demolition crew in the prehistoric world."

In the days that followed, Xuanbao worked on perfecting every detail of the "Martial Path Cave Heaven Scripture" in the cloud, making it more in line with the current situation of the human race, combining potential and security, while also "spying" on the dynamics of the human race below with great interest.

He saw messengers sent by Lieshan traversing mountains and valleys, spreading the message of "a century of preaching" in the most primitive yet resolute way; he saw various tribes begin to consciously record knowledge in a crude but effective manner; he saw people observe sunrises and sunsets, the growth of plants and trees more carefully, and even begin to try to summarize patterns; he saw that conflicts between tribes seemed to have decreased, and a mysterious expectation and cohesion were quietly spreading among billions of people.

Ultimately, Xuanbao deduced the *Martial Path Cave Heaven Scripture* to be comparable to the Golden Immortal Realm of the Primordial World. However, the *Martial Path Cave Heaven Scripture* also incorporated settings from numerous movies, games, and novels Xuanbao had previously watched, resulting in countless variations. Looking at all this, Xuanbao felt that all the mental effort he had put in had not been in vain, and his heart was filled with satisfaction. He knew it was time to spread the *Martial Path Cave Heaven Scripture*. Therefore, he transformed into a stream of light and descended upon Shouyang Mountain.

"Martial arts are the edge, the cave heaven is the root... This is the path of 'self-reliance' that I have sought for the human race."

Xuanbao understood immediately, and Daoist energy flowed from his fingertips, as if sketching a blueprint for the future in the void.

Happy New Year! Wishing everyone a prosperous and auspicious New Year, and may all your wishes come true! May you make a fortune after the New Year! o>_
