Back within the Shinobi World Star Domain, the light of Tsubasa's chaotic fire meteor had become as faint as a Fire Fly. He barely maintained his form, and slowly descended with his wife and children into the war-torn core starfield, where the allied forces had begun clearing the battlefield in the core area.
All the survivors of the Allied Shinobi Forces, as well as those who had witnessed the battle in the starry sky through various means, silently gathered around, and endless sorrow and solemnity filled the starry sky.
Tsubasa's fiery body began to disintegrate inch by inch, scattering like sand in the wind. He looked at his wife and children surrounding him, and the last trace of warmth and remorse emanated from the flames of his soul.
"I'm... sorry... from now on... you'll have to rely on yourselves..." His voice was so weak it was almost inaudible.
"No! My husband! You'll be alright! We can definitely save you!" Tian Mai gripped his fading hand tightly, tears streaming down her face. Tian Uguisu, Tian Zhiyun, and Tian Yukihime were already sobbing uncontrollably. Tenpi and Tenchu had red eyes and gritted their teeth. Tian Yu, on the other hand, endured her grief and continuously channeled her pure life energy into her father's body, but it was as if a stone had sunk into the sea.
Tsubasa shook his head slightly, his gaze finally settling on Tian Yu, filled with expectation and entrustment. Then, he slowly swept his gaze over each of the Shinobi World warriors present, his eyes filled with encouragement and farewell.
Finally, he looked up at the starry sky, which was gradually returning to calm but still bore the scars of war, and the flame of his soul emitted its last glimmer.
" The Mirai the Shinobi World... is in your hands..."
As soon as he finished speaking, his last fiery body completely dissipated, turning into countless glittering particles of light that rose into the air. At the core of those particles, a golden lotus seed, about the size of a fist, perfectly round, and radiating a faint aura of chaos and immortality, gently fell to the ground.
The Immortal King Tsubasa burned his soul, his physical body, and the very essence of his innate treasure. In the end, he fought to the death, his body and soul annihilated, leaving behind only this lotus seed that carries the last trace of his life and the essence of the Great Dao.
Heaven and earth grieved, and all things fell silent. Countless warriors knelt silently within the star field, and the will of heaven and earth murmured, as if the entire world was weeping for the passing of its guardian.
Tian Yu reached out with trembling hands and carefully caught the lotus seed, which was still slightly warm. She pressed the lotus seed tightly to her chest, feeling the faint yet incredibly familiar life force within it, and tears finally streamed down her face.
"Father... I won't let you down..." she choked out, making a vow.
The news of the Immortal King Tsubasa's sacrifice to repel the powerful enemy quickly spread throughout the entire Shinobi World. The world mourned, and all spirits grieved. But after the sorrow, an unprecedented sense of unity and determination emerged.
The Immortal King sacrificed his life to buy them time and protect their Mirai. They cannot let this sacrifice go to waste.
Under Tian Yu's supervision, the golden lotus seed, transformed from Tsubasa, was solemnly planted in the deepest part of the forbidden area of Shikkotsu Forest, a place where Natural Energy was most abundant and the laws were most complete. Tian Yu personally set up multiple protective barriers and Great Spirit Gathering Formation around the lotus seed and decided to stay there for a long time to personally protect and nurture this lotus seed that represented her father's hope for rebirth.
She believed that with careful nurturing, gathering the wishes of all beings in the Shinobi World and the origin of the world, her father would one day be able to be reborn from this lotus seed.
At the same time, the entire Shinobi World civilization entered an era of rapid development and perseverance.
All the major ninja factions, Immortal Cultivation holy lands, and all surviving forces united as never before. Tian Yu, as Tsubasa's successor and new strongest, though grieving, resolutely shouldered the responsibility of leadership. She joined forces with her mothers ( Tsubasa's wives), the original Golden Core Immortal Venerable Venerables of the Shinobi World, Tsubasa's disciples, and the heads of various Sage-Rank Clan to form the " Shinobi World Revival Council."
Based on the data and insights gained from the battle between Tsubasa and the Ōtsutsuki, as well as some life technology recovered from the wreckage of the destroyed Ōtsutsuki spaceship, and combined with the existing rune technology, Senjutsu, and Puppet Technique of the Shinobi World, a massive technological explosion began.
More efficient energy extraction and utilization technologies (such as mimicking the way the God Tree absorbs energy from the stars), more powerful individual combat armor and weapons (incorporating Natural Energy and Senjutsu runes), larger starship designs and manufacturing (to cope with Mirai interstellar wars), a more rigorous but more effective nationwide Body Tempering... One plan after another was proposed and quickly put into research and development and practice.
The original Mars star system and other strategic locations such as Mars were transformed into massive space defense bases and shipyards. Countless engineering puppets and ninjas worked day and night to build solid defenses in the asteroid belt of the star system where the Ōtsutsuki Clan would appear, as well as in more distant star systems, deploying countless automated defense weapons and reconnaissance arrays.
Everyone knew that the Ōtsutsuki Clan would not give up easily. The next attack would only be more ferocious. Without the Immortal King Tsubasa, they had to become strong enough before that day came, strong enough to rely on their own strength to protect the land beneath their feet and to protect the peace and hope that the Immortal King Tsubasa had bought with his life.
Within the forbidden grounds of the Shikkotsu Forest God Sealing Sect, the golden lotus seed lay quietly in the vibrant soil, absorbing the essence of heaven and earth and the will of all living beings, shimmering with a gentle light. Meanwhile, in every corner of the Shinobi World, countless people were striving for a shared Mirai. The seeds of hope had been sown, and a civilization reborn from the ashes of war was advancing towards the stars at an unprecedented speed.
Time has passed, and ten years have gone by since that interstellar war that determined the fate of the Shinobi World.
Ten years is but a fleeting moment in the vast universe. But for the Shinobi World that survived the catastrophe, it was a long and important period of recovery and development.
Under the leadership of core members of the Ten Family, including Tenchu and Tian Yu, as well as Tsubasa's disciples, the Allied Shinobi Forces were reorganized, and their technology and cultivation civilization experienced a leap forward spurred by the war. Utilizing some Ōtsutsuki biotechnology salvaged from the battlefield, combined with their own Sage Mode system, they developed more powerful warships and weapons. At the same time, the promotion and research of Body Tempering such as the Xingchen Body-Tempering Art and Senjutsu Chakra reached new heights.
As the only Immortal King in the Shinobi World, Tian Yu has become the de facto spiritual leader and the strongest fighting force. She inherited her father's sense of responsibility to Guardian Ninja world. Although she spends most of her time in the sacred Shikkotsu Forest, guarding and nurturing the lotus flower that her father transformed into, she also handles important matters in the Shinobi World while constantly consolidating her Immortal King Realm and studying the laws of life and soul, hoping to find a way to completely repair her father's soul.
