60 Episode
The protagonist transmigrates to the Primordial Era, where the human race and the demon race stand as equals in power. He awakens a system that allows him to directly refine great demons—either they submit, or they are refined into Ancestral Demon Source Gold. With this source gold, he can purchase items from the system shop, paving his way to invincibility in the Primordial Era.
