Review Detail of Lub_Hli_Ci_Ntsa in The Wielder of Death Magic

The MC is very stupid, being the Heir to the God of death but doesn't train in any of Death's ability even though Death gave him advice on how to become stronger. He then goes and waste time raising a baby instead of training. So he wasn't able to save his hometown from getting destroyed and ends up dead and turned into stone by the princess. Story would have gone better if he went and trained with the God of Death after he died from the princess curse then return.
