Centennial Elegy

"Are you going to kill him?" "Kill who?" "Anyone who stands in our way... Or a monster." The most powerful demon in the world is hidden in "Pandora's Box" discovered by an expedition team in the Pacific Ocean. One day, Ke Ai accidentally opened the magic box and found that his superpowers could suddenly be used... But this did not seem to be a good thing, because becoming a hero comes with a price, and those with superpowers will be abandoned by the ancient alchemy. Superpowers, alchemy of equivalent exchange, doom plan, astronomical library, night watchman... This is a story about unknown heroes. Countless generations of people have been fighting against the "origin beast" for hundreds of years. They were born unknown and died brilliantly. If you were given a chance, would you save the world or make trouble in the world of mortals?
