Versatile Mage: I Can Be Resurrected Infinitely

Can you just go and get the Ancient King Evil Armor? Anyway, you can be resurrected infinitely, so you are not afraid of being corroded by the undead. Moreover, it was once an undead attribute, so it is somewhat resistant.

How about becoming a Red Devil directly, absorbing negative emotions and growing up, growing old quickly, and becoming the leader of the monarch in a few years?

Although I haven't watched it yet, is the protagonist's resurrection from death the ability of Doomsday?

The classification of the work should be that of a derivative fanfic, but the label was wrong when I created it. I don't know if there is anything wrong with it (／_＼) Big complaint

I borrowed it from the Internet. A friend sent it to me, so I copied it... The picture I appropriated [Soul Lamp·Tanatos] is based on this description.
