Savior, Can You Die in My Hands?

I have experienced a green world destroyed by plants, I have fought with terrifying ocean beasts in the endless depths of the sea, I have seen the gorgeous world of steam ancient martial arts, and I have been trapped in a pale nightmare... Countless worlds, just to finally reach the end point prescribed by fate... Why did I, a college student, come to this strange world? Why should you be dictated to your own destiny? Since you can't go back, then come! Super powers, technology, ancient martial arts, magic, cultivating immortals, runes, source energy... No matter what it is, I want it! I want to become stronger, strong enough to change the world, strong enough to face the savior at that time, and then... Let him die in my hands! This novel and its characters are purely fictitious.
