A tale of a demon, Lev Geiss, who is hated by heaven and earth. He meets his end at the hands of gods and heroes but gets reborn 200 years into the past.

With memories and experience of his first life, he will rise again as a demon.

His sole purpose is to grow stronger and he will kill anyone who stands in his way. Fear? Anger? Love? He knows none of those useless emotions.

Additional Info (for those who are still not sure if the novel is worth reading)

-The MC is a savage. He will not hesitate to rob/kill anyone.

-The power system in the world is similar to cultivation in the sense that there are stages and tiers. It's more like magic + cultivation.

-The MC gains power slowly. The OP part is not his strength but his knowledge and schemes. His attitude is also kind of OP.

-At least one chapter every day and 1000+ words each chapter.

-If you prefer something less serious, check out my other fiction ( I Became a Legend Before I Realized It ). That one is a romance comedy isekai.
