Doomsday Immortality: I Can Evolve If I Die in Battle

My father always said that I would die a tragic death, just like my mother. Well, I died. Then he died again. But he did not die cowardly. I died like a real man. When the doomsday tore the sky apart and countless monsters razed cities to the ground, Zeffion died under the first wave of disaster. But he did not just return to the dust. Instead, he awakened the immortal core - this mysterious power would reshape him and become stronger every time he died. But this power has an iron rule: it rewards courage, never ignorance. Suicide, surrender, or trying to take advantage of others will not gain any benefit. If Zefion wants to become stronger, he must face enemies far beyond his own limits... And he must hold on until the moment of a desperate fight before his power is triggered. Most people only have one chance to change their destiny. And Zeffion will continue to die until fate succumbs to him.
