"Dual main lines + no system + no invincibility + non-game text"
Injuries cannot be healed by time, and hatred cannot be erased by death!
The story of the protagonist's past life (human) and present life (undead) is interspersed with two main lines. It is expected to be about two hundred chapters. The two lines are combined into one and begin to tell how the protagonist avenges his previous life in this life.
(PS: Regarding the undead creatures in this book, use "him (her)" if they have names, and "it" if they don't have names.)
