I Just Wanted to Raise My Son... Why Is Everyone Challenging Me?

After surpassing the impossible and reaching the legendary Eleventh Star of Aura, the strongest knight in history shattered the limits of humanity—and alarmed the gods themselves. Branded a threat to the divine order, he was sealed away for centuries. When he awakens in a changed world, the age of heroes has faded, magic has strengthened, and his name has become myth. Instead of reclaiming glory, he chooses something unexpected: a quiet life. In a crumbling alley, he finds a starving child, a beggar with mysterious potential, and adopts him as his son. With overwhelming power and forgotten knowledge, the knight builds a home from nothing. But peace doesn’t last long. Now, Kael Zeroth must decide: remain hidden… or rise once more and defy the heavens to protect the family he chose. — Description from novelcodex.org
