With the falling of nuclear bombs, the mutation strangely adapted and became an entirely new element.Those who couldn't withstand this mutation became beings tethering on the edge of life and death, becoming undead.Only a small population remains on the earth now.In this small population, some can adapt to the mutation and awaken unique powers in the apocalypse, while others are entirely unaffected, still like normal people.Ray was just a normal E-class awakener, but a faithful purple crystal changed everything.Through the purple crystal, a “system” activated inside him, which could allow him to get stronger the more he spreads his genes.Necromancer, wizard, martial artist to sorcerer - every single skill was possible as long as he spread his genes.From that moment, Ray walked the path of spreading his genes “for the sake of humanity.”#no ntr, yaoi or yuri
