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!

Travel through the world of Naruto, activate the god-level forging system, and a super strong man has risen in the ninja world!

One after another artifact appeared in the ninja world one after another,

So the whole world is boiling!

Grass Pheasant Sword, Ten Fist Sword, One Hit Kill – Murasame!

The beheading sword, the Zanpakutō, the flowing blade is like fire・d solution!

Red Sand Scorpion: “My puppet is not worth mentioning in front of his ninja gear!”

Four Raikage: “What?

He can slash through my Thunder Dun armor with a single knife? ! ”

Madara Uchiha: “I can’t even beat his ninja gear. What kind of fourth ninja war is going on?”
