After their cultivation levels skyrocketed, Tsubasa didn't let his disciples rest on their laurels. Instead, he began the third stage of training—comprehending the laws of heaven and earth and searching for their own "Dao"!
"The laws are the fundamental principles governing the operation of the world. The intensity of fire, the resilience of water, the freedom of wind, the swiftness of thunder, the weight of earth, the vitality of wood, the stillness of yin, the creation of yang, the mysteries of space and time, and so on... Only by comprehending the laws of the elements can one truly unleash Immortal Level power, and even, in the Mirai, construct one's own Immortal King domain." Tsubasa's voice echoed in the lecture hall, and he released his domain for the disciples to experience its profound mysteries.
Based on the attributes and traits that his disciples excelled in, he personally led them to various elemental treasure lands that the Shinobi World and even the Tsubasa had opened up and drawn from space.
The Extreme Lightning Abyss is located deep within the former site of the Kumogakure in the Lightning Province. It was activated by Tsubasa with his Immortal Power, gathering the essence of thunder from the nine heavens. Thunderstorms rage here year-round, with purple, black, and even golden divine lightning dancing wildly like dragons and snakes, permeating the air with an aura of destruction.
Sasuke stood at the edge of the abyss, his Rinnegan fixed on the raging core of lightning. He no longer viewed Lightning Release merely as an offensive technique, but attempted to comprehend the true meaning of the laws contained within it: "Life force within destruction," "extreme speed and penetration," and "judgment and punishment." He stepped into the thunderstorm, letting the lightning strike him, protecting himself with Immortal Power, analyzing it with his Rinnegan, and drawing upon the lightning with his Sage Sword, gradually condensing a wisp of his own "Thunder Sword Intent."
The Endless Wind Cave, located in the desert of the Land of Wind, is a natural spatial rift where the elements of raging wind converge. Here, Naruto experiences the formlessness, freedom, and unbridled nature of the wind, while also feeling the tearing, ferocity, and destruction of the storm. He recalls Tsubasa's words that "the laws of space are often accompanied by wind," and attempts to combine Wind Release with the Flying Thunder God Technique. His figure appears and disappears within the wind tunnel, and his understanding of space rapidly improves. He even begins to ponder how to integrate the intangible power of " Talk no Jutsu " (unwavering belief and persuasiveness) into his own "Way," forming a unique "Wind of Belief" or "Power of the King's Way."
Above the Valley of the End, Tsubasa used immense magical power to draw upon the power of the celestial Xingchen, creating a temporary "Ancient Starry Road." Hinata walked along this road, her Tenseigan resonating with the countless Xingchen. She "saw" the birth and death of Xingchen, the movement of star orbits, and the balance of gravity and repulsion. Her " Eight Trigrams Xingchen Palm " began to incorporate the true laws of Xingchen motion; with a single strike, it seemed to unleash the crushing power of stars, its power surging. Simultaneously, she traveled to the Supreme Yin Cold Spring inside the moon (the place where Kaguya Otsutsuki was sealed), to comprehend the laws of extreme yin, tranquility, sealing, and the soul, compensating for the excessive yang energy of the Hyuga Clan and pursuing a balance of yin and yang.
The remnants of the God Tree are located deep within the Shikkotsu Forest, piled up with the remnants of the Ōtsutsuki God Tree, brimming with the most primal and boundless life force. Here, Rin'er merged seamlessly with the Natural Energy, and her Wood Release was no longer simply about creating trees, but rather contained the life laws of "growth," " Reproduction," "healing," and "absorption." At the same time, Tsubasa also took her to the " Ten Thousand Poisons Swamp," a place filled with the aura of death and decay, allowing her to experience another side of life—"withering," "corrosion," and "devouring." Rin'er began to try to integrate these two seemingly opposing forces into her Wood Release, creating the " Extinction Life-and-Death Wood," which embodies the concept of the cycle of life and death, possessing mysterious and powerful strength.
The Path of Xingchen is the ultimate realm of pure power. Tsubasa led him to a colossal crater formed by an ancient meteorite impact, where powerful impact laws and the distorting force of Xingchen magnetic fields remained. Here, Xingchen honed his physical body, experiencing the ultimate explosion and transmission of power. Afterward, he was thrown into the Earth's core furnace, enduring the scorching flames and the tempering pressure of the earth, treating his body like diamond to be refined, attempting to open deeper levels of the " Xingchen Meridians" and "Earthly Fiend Apertures" within his body.
Tsubasa opened a passage connecting the Kirin Cat to a distant " Xingchen." On the Xingchen, the Kirin Cat endured arduous cultivation in an extremely harsh environment. Facing extreme threats to its survival, the Kirin Cat's bloodline awakened, granting it the inherited memories of the Kirin demon beast and a deeper understanding of its innate laws such as wind, fire, thunder, and the auspicious Kirin. At the same time, Tsubasa set up Five Elements Rotation Formation on the Xingchen, allowing the Kirin Cat to frolic in the Five Elements Revolving Pool, balancing the five elements within its body and laying the foundation for condensing its Demon Core and transforming into a stronger divine beast in the Mirai.
The disciples, though not formally registered, also had their own unique experiences:
Kageko Nara was sent into the " Formation Evolution Sand Table " to deduce the grand array of heaven and earth and comprehend the laws of "binding", "evolution" and "calculation".
Tianling entered the " Yan Nation National Fortune Secret Realm " to comprehend the kingly way of "rule," "order," and "gathering power."
Madara Uchiha (childhood) was allowed to "walk through the Ten Directions of Hell," wandering through various perilous Hell places, experiencing the boundary between life and death, and stimulating his Rinnegan.
Mito Uzumaki (childhood) enters the " Shikkotsu Forest Holy Land God Sealing Sect," directly confronting the origins of various powerful Sealing Jutsu and understanding the various laws of "blockade," "isolation," and "contract."
Haruko, in the "Ancestral Shrine of the Shrine Maidens" (rebuilt by Tsubasa ), communicates with the remaining thoughts of the shrine maidens of past generations, perfecting the shrine maiden's way of "purification," "prophecy," and "spiritual communication."
Each disciple, within their own elemental treasure land, immerses themselves in the world, resonating with heaven and earth, and merging with the laws. They no longer merely learn and absorb, but begin to create, to form their own unique understanding of the "Dao." This process is fraught with hardship and danger; disciples sometimes make mistakes in their understanding and suffer backlash from the laws, but under the protection of the Tsubasa Avatar, they ultimately escape unscathed.
When everyone returned from their respective elemental treasure lands, their auras became more restrained, but deep in their eyes, there was something called "Daoist charm." That was the foundation for their Mirai path to becoming Immortal King.
Having comprehended the laws and gained power, the next step is to transform all of this into tangible combat strength, growing and learning through battle. Tsubasa's fourth stage of training—real combat! Insanely intense real combat!
He used his Immortal King status to gather all the top experts currently available in the Shinobi World, forming a "sparring squad." This lineup was extremely impressive.
Kakashi Hatake ( Early Golden Core stage, Lightning Release, Dōjutsu, Tactical Master), Obito Uchiha ( Peak Foundation Establishment, Space-Time Ninjutsu, Yin-Yang Release ), Might Guy ( Peak Foundation Establishment, King of Taijutsu, Eight Gates Released Formation ), Asuma Sarutobi ( Peak Foundation Establishment, Wind Release, Senjutsu Chakra Blade), Tsunade ( Middle Golden Core stage, Super Strength, Medical Senjutsu ), Jiraiya ( Early Golden Core ), Mei Terumi ( Peak Foundation Establishment stage, Two Kekkei Genkai ), A Yotsuki ( Peak Foundation Establishment, Lightning Release Armor, Speed), Killer B ( Peak Foundation Establishment, Lord of the Eight-Tails, Swordsmanship), and many other Golden Core Immortal Venerable Level experts from the Ten Family... Furthermore, Tsubasa even used his Immortal Power to condense some energy phantoms with special abilities, as well as projections of the Ōtsutsuki Clan troops simulating a space battlefield!
The training ground is a specially designed "All- Myriad Phenomena Martial Training Realm and Cosmic Starry Sky," which can simulate various extreme environments—deserts, glaciers, lava fields, deep seas, gravity anomaly zones, spatial disorder zones, and so on.
