INFO CHAPTER: QUICK CULTIVATION BASICS(Good even if you know Xianxia)
Cultivation is to draw qi into the body to strengthen it, and as you absorb more qi(spiritual energy) you evolve the realm you're in, and every realm gives a qualitative leap in life level.
You eventually evolve into a god-like being.
The realms for this book(not really important): Qi refining, Foundation Establishment, Golden Core, Nascent Soul, Divine Transformation, Void Refinement, Enlightenment, Quasi-Saint, Saint, Saint King, Quasi-Emperor, Great Emperor.
Immortal realms: Earth Immortal, Profound Immortal, Silver Immortal, Golden Immortal, Tiayi/Great Golden Immortal, Immortal King, Immortal Venerable, Immortal Emperor(the mc)
A vampire in twilight is equal to a Foundation Establishment cultivation… maybe a bit generous, but we will go with that.
The MC will only use a couple abilities.
Palm Technique: To send them flying with minimal damage, for takedowns.
Fist Technique: To crush/ destroy their bodies.
Foot Technique: For speed, agility.
Sword Finger: The most offensive technique to send out a sword slash of qi.
Spiritual control(telekinesis): Self explanatory.
Fire technique: Weak pyrokinesis, to finish off vampires.
Divine sense: Not really a technique as it comes with increased cultivation, it's like observation haki in One Piece… kinda.
For reference, a Golden Core realm cultivator can easily wipe out an entire town and probably rule the world. A nuke can kill them but it has to hit them, they might just fly out of the blast radius.
As for Nascent Soul… that's an Avengers level threat, can rule the world, can survive one or more nukes.
Again don't think too much about the realms. It's not important. In the end it's a Twilight fic and you can as a Twilight enjoyer read with peace of mind.
