Blood Shaper - Chapter 1Book 4:

Sam Sanderson is envied by many for his job, however he himself didn't seem to like it much.

Due to his expertise in nanotechnology he was tasked with monitoring the state the Valkyries, humanity's strongest weapons who all just happen to be made into gorgeous females.

Forbidden from even touching any of them, Sam spends his days in agony watching flowers he couldn't hope to touch. However one day all of that seemed to change.

In this world, strong warriors are needed in order to conquer the hot crimson desert. The Pareia Tribal-Chief’s first-born son, named Yulian Provoke, routinely gallops through the stormy deserts alone. Only to find someone of destiny – an otherworldly man that would change his fate forever. This same young child who struggles to find purpose while embodying both ambition and revenge into his very own hands as he awaits that faithful day of confronting a particular person that was, supposedly, the culprit of his blood-mother’s death. At first, he was alone; but then after, he forms the RED STORM division – a group of powerful warriors at his command – in hopes of Conquering the Desert, braving towards those who oppose him, and bringing great fortune to his tribe.

After living in a desolate land, where there wasn’t even a single blade of grass and hunger was an everyday reality, Min Sung finally returns to Earth: his home.
