Reconstruct the World from Blank Spaces

They said that I had been "formatted" three times by this magical continent. The first time, when I was five years old, was to hide my talent. The second time, at the age of eighteen, was to plunder blood. The third time, at the age of twenty-two, was to heal trauma. Every time, someone said to me: This is for your own good. My name is Kai Wein, an adventurer with nothing. Don't remember hatred, don't remember love. But my sword remembers fighting, but my soul can hear it - this world is slipping into the abyss of death on an "absolutely correct" path. Until a senior placed a rusty coat of arms in my palm. She looked at me, her eyes seeming to penetrate time and space: "Child, you are not sick. You are the last wrong fill-in-the-blank question left by this world for itself." So, under the floating city where divinity reigns supreme, in the roar of the eclipse tide—— My "mistake" that was erased three times, this "loophole" that is regarded as blank by the whole world. I decided to use everything that was taken away from me to fill in my answers for this hopeless perfect world. Starting from the third formatting, I use my blanks to reconstruct this world.
