I use demon seeds to cast immortality

When he woke up, Han Li traveled to a chaotic world where evil spirits were rampant.
Here, there is an immortal demon saint who is causing chaos in the world, and the Supreme Being is guarding the universe.
Traveling through this world, Han Li obtained a demon seed from heaven and earth. By killing creatures, he could obtain blood and energy, improve himself, and practice martial arts to derive supernatural powers.
From [Thunder Fist] to [Thunder God's Wrath], from [Kunpeng Transformed into Feathers] to [Swallowing the Sky and Devouring the Earth]!
Immortal demon body, immortal!
There are many corpses on the road to immortality. Han Li embarked on a martial arts path to immortality where the world will be destroyed but I will never be destroyed!
