Fighting for Immortality from the Beginning

In a nascent world, everything is just the beginning, and there is no end yet. A world where human life is like a piece of grass and destiny is like a saint. God? Is he really the creator of this world? Humans can only live a lowly life? I don't believe it! I will use my power to break through the sky, kill the god, and destroy his rules. Follow a path of becoming an immortal based on your own flesh and blood and respecting yourself. ******* This is a story about cultivating immortality, but it has different excitement, different ideas, and different angles. I hope everyone will like it.
