Good assassin/magic manga?

[Justamoldycheeto]

I’m really looking for something like undead lord of the palace
Kage no eiyuu
Mercenary enrollment
Omniscient readers viewpoint
The greatest mage returns after 4000 years

Anything with magic like this. Preferably vampire/ assassin
Isekai is always welcome

I heard that the manhwa Solo Leveling has quite the popularity.
