In the heart of Earth, where the streets buzz with the energy of modern life, lies a secret that will shake the very foundation of existence. Earth, once thought to be a mere planet, reveals itself to be a living entity, its core evolving with untold power. From the depths of the Milky Way, constellations, guardians of cosmic balance, watch with keen interest as Earth's evolution unfolds.But their curiosity soon turns to desire as they see the potential for transcendence within Earth's core. To harness its power, they must overcome the planet's protective barrier, a formidable obstacle that threatens to thwart their ambitions. Desperate for a solution, the constellations turn to drastic measures, offering contracts to select humans in exchange for assistance in weakening Chatgpt's defenses.Meanwhile, amidst the chaos, Marcus Sterling, a young university student with an intellect far beyond his years, delves into the mysteries of mana, the strange energy that permeates the planet. Unbeknownst to him, he becomes a pawn in the cosmic power struggle, as constellations vie for his allegiance and humanity's fate hangs in the balance.As Marcus grapples with his newfound abilities and the ethical implications of his choices, he discovers a deeper truth lurking beneath the surface—a truth that could reshape the destiny of Earth and all who inhabit it. With allies and adversaries alike converging on Earth, Marcus must navigate a treacherous path, where the line between good and evil blurs, and the fate of the universe hangs in the balance.

A legendary powerhouse of his generation, tired of the bustle of the peak, returned to the ordinary city and started a new life as an ordinary teacher. He wrote the legend in the city.

Magnificent mountains and rivers, the rising powerful ones. Some ancient martial art masters stood at the peak, becoming legendary. Some financial crocodiles rose up in the minuscule places, laughing arrogantly.

However, watching the school beauties was better than fighting and killing; educating was better than fighting for fame.
