Core of Light

On the vast Wuji Continent, the Kingdom of Light and the Federation of Darkness have been at odds for thousands of years. Legend has it that practitioners who fully develop their core strength possess earth-shaking abilities. But no one knew that something had quietly changed after the vision of "Nirvana". Twelve years later, a boy with brown hair and brown eyes was taken away from the asylum in a border town by a mysterious girl. His core was lit up with pure darkness - so pure that he didn't look like a citizen of a kingdom of light. The girl taught him how to practice, made a contract with him, and then turned around and left a few days later, leaving only a golden scale behind. She explained nothing. But he remembered the moment when he broke through to become a bachelor, and there was a ray of white light in the deepest core, which flashed away. From the border valley to the wild academy, from the promise of a scale to the crossroads of the destiny of the continent—— When the undercurrents of major forces surge, and the balance between light and darkness is at stake, the secret deep in the heart of a young man that even he himself has not seen clearly may be the only chance to break the situation.
