The title is a bit misleading. It's not really a skill or points based system, it's mainly a gacha system. After he breaks through to Qi cultivation he gets a gacha pull add-on that costs a big chunk of his points, naturally that becomes the main thing he uses them on. There's no real struggle to find new skills, no effort to find new cultivation methods that can improve talent, or do other unique things, just pull gacha. There are always enough points to cover maxing out any skills, and exceeding the max grants knowledge that wasn't part of the original skill, so no need to try to find or make anything better.

Unique. Basically the "immortal from the start" style but as a zombie. He uses makeup to blend in and lives in the capital as an undertaker. His system is that he can grant salvation to the spirits of the dead. Doing so makes the undead mindless, which is a nice nerf, but he not only gets the memories of any dead he's used this on, he also gets physical rewards, which is a bit much. He also ends up with so many skills from these memories that not even the author knows what he can and can't do. The pacing is kind of slow. A lot of arcs are just adventures he goes in, but doesn't really gain anything from. The overall style is influenced a lot by Chinese horror, like Ghost Blows Out the Light. The Xia aspects are more Wu than Xian, at this point.
