HP: A Magical Journey - Chapter 14: Letters Arrive, and The Decision

The MC (Minato) is a college student who died in a plane crash and was reincarnated in a fantasy world. He was raised alone in the wilderness by his succubus mother, and now he tries to make his way as an adventurer.

He was the powerful and influential heir of B City, the merciless head of the commercial world, but the divorce papers made him lose his cool.

“Sign the divorce papers, daddy,” said the 5-year-old boy.

This man had the divorce papers thrown in his face by his wife six years ago, and was now being pushed by his own son to sign the papers.

“That would make you a single-parent child,” said Gu Juexi coldly.

“Mommy said unicorns don’t exist but men like you do,” the boy leered at his father and said.

Gu Juexi’s face fell. ‘That damned woman.’

“You haven’t signed the papers,” the boy reminded as the man left. As usual, the door shut in his face.

Good lord… Dad and mom are not getting a divorce and are giving him a baby brother? How worrying!

I am the sword.

Killing a man amidst a thousand miles, no one dares take ten steps.
Killing a man amidst a thousand miles, no one can take ten steps.
Killing a man amidst a thousand miles, ten steps? Not possible!

I am the sword, the sword is me,
On the path towards heaven, each shall wield their own.
