The Illegitimate Son Became a Monster Summoner

Kain, a concubine’s son viewed as a worthless piece of trash by his family, is abandoned by his own siblings in the depths of an abyss. On the brink of death, he hears the dark echoes of the chasm. Awakening a god tier talent called Dark Eclipse Echo, Kain returns from the dead. Armed with a summon that evolves from an ordinary monster into an epic calamity, he survives the abyss and embarks on a dark path of revenge to reclaim his honor.
