Review Detail of Novelreeead in Reborn As A Ghost: Time To Build My Undead Army!

I'm one of your readers who read almost all of your novels. just want to ask sir author does she had a power like necromancy and can gain a servant through dead creatures? like gaining some high ranking/general undead because she defeated a high rank monster or even human - to make a good example : solo leveling. lately I've been craving for necromancy novels but all the things i tried to read only had a average power system in regard to necromancy. like they can only summon skeleton or something sh*t through their skill in game like manner and didn't even give their respective MC's to revive a dead creature they defeated or found as undead. so ihope this one got something like that
