The Experimental Log Of The Crazy Lich c1-841

Legend says every transcender who breaks through the boundaries of space and time receives a gift from the world—a 'Golden Ring.' For one man who finds himself trapped in the skeletal body of a lich, that gift is the 'Evil Lich System.' Formerly a Holy Knight now forced onto the dark path, he must navigate the absurd and often malicious quests provided by his system.

As an undead being who has lost his sense of taste and lives in constant annoyance of the mischievous children who terrorize his laboratory, he must balance his survival against the bizarre requirements of his system. From petty pranks on local children to grand, world-shaking plots, he maneuvers through a world that views him as a monster, all while trying to maintain some semblance of his former sanity.
