Naruto: I Can Upgrade My Techniques Infinitely - Chapter 28: Riddlers, Get Out of Konoha

SSS Beast Apostle System and Survival Racing in Apocalypse.

When the aliens invaded earth, they didn’t come for its resources as many doomsayers had proclaimed throughout the years.

Instead, they came for fun.

They came, flattened earth’s biggest cities and turned the world into a planet-sized stadium for their civilization.

The sport?

Survival Racing.

Ferocious alien beasts were unleashed upon the ruins of the world along with thousands of alien death-row fugitives who were only told one thing: Kill the humans, survive the year and regain your freedom.

Elliot was a survivor. He died right before he entered the final 15 days of the Games.

But as his consciousness began to slip away, a metallic voice rang out within his soul.

Mission failed.

Activating sponsor’s Boon: Reverse Time Walk.

Activating sponsor's Boon: Beast System.

Welcome to the Beast System. My name is Hawk, your AI.

EXCERPT from Chapter 1:

Elliot screamed in absolute exhilaration as he smashed his foot on the brakes, just enough to fully utilize the power of his ceramic brakes but not so much that his tires locked up. He went from two hundred miles an hour to forty miles an hour in a heartbeat.

He entered the sharp corner from the outside at the maximum entry speed and skillfully brought his car to the threshold of his tire’s grip.

SCREEE!!

He took the corner at record speed like a professional racer and then floored the pedal to the metal once more!

I didn’t know this was a world inside a game. And I didn’t know my master was a mid-boss. “No way… wasn’t she supposed to self-destruct because of her personality?!” …I’m sorry.

Everyone believes Lin Zhao Xi’s a genius.

Only she knows she’s looking back on years of experience in math competitions as a basis to “cheat”.

Until one day, her idol quietly looks at her.
