I just hope this is not like Solo leveling type. There are a lot of ways to counter necromancer like Robots, cyborgs, any lifeless machine inscribe with magic. Even strong golems or ents. Maybe angels of light. Priest paladins. Strong necromancer makes me nauseating almost puking at most story lines. Super strong without any adversity. No story at all to share just a short words to describe a story with op characters so strong finish all foes the end. No struggle no pain no drama. Well just need to look at the arts that makes it good but nah. Just total waste of time in the end. Like you just need to finish it because you started it. Then hoping to get to final chapter because it's became totally dull to read.
