No system + no time travel + non-cool story
"I know nothing can be accomplished overnight, so I sacrifice everything in my first half of life, just for this long road of cultivating immortals."
When soil accumulates to form a mountain, wind and rain arise; when water accumulates to form an abyss, dragons are born; when good deeds accumulate to form virtues, the gods are content and the holy heart is ready.
When you accumulate Tao to become an immortal, you will be invincible in this world.
An Immortal does not differentiate between good and evil, nor do they care about the distinction between black and white. They do not ask what is right or wrong, and consider all living things as dogs. In spite of everything, Immortals pursue the Dao with bitter resolve.
Any being who disturbs my Dao, good or evil, will be forced to meet their karma, reduced to nothing more than ashes.
