National Destiny: Burning Lifespan, Refining All Races into Demons

The country bound the weakest human race, and nine of the ten chosen ones died tragically. The only survivor awakened a hundred times his understanding and actually developed the magical skill of burning longevity and cultivating immortality in the magical world. "A hundred times the lifespan of burning? A hundred times the cultivation speed!" Breaking through the realm to extend life? Then burn more life and sprint to the realm! Lead the remaining human race to cultivate demons and fight against alien races, using flesh and blood as wages. Elf magic destroys the world? The human race's magic power cramps and sucks marrow. When the Throne of Bones was cast, the Elf Saint prostrated herself to offer the land. "I send you the blood and bones of all races, and congratulate the human race on their ascension to the gods!"
