I Have the Power of Time and Space from the Start. What Should I Do?

1.7 billion years ago, the shattering of rules... the collapse of space and time...

1.7 billion years later, the body of thought... a life path gone astray...

Is this how [my] fate is destined to unfold?

"No."

"I refuse to accept this."

"I won't walk a path laid out for me."

"Fate's cruel tricks are utterly pointless."

"Then I'll be the most obsessive, most stubborn mediocrity of all."

"All the self-loathing and tears born of resentment... cast them all behind me. Every wave of hardship and scorching blaze that stands in my way... I'll cut them all down with my blade."
