Summary
After World War I, over 70 German ships interned at the British naval base Scapa Flow mysteriously disappeared…
More than two decades later in 1940, the world is engulfed in a new war against the Mundus Empire, an invading force from another dimension. Having conquered the Southern Hemisphere and steadily expanding its territory, the Mundus Empire has finally set its sights on the Northern Hemisphere.
The United States Pacific Fleet is annihilated off the coast of Hawaii, and the Imperial Japanese Navy’s vaunted Combined Fleet suffers a crushing defeat at the hands of the Mundus Empire’s fleet that has invaded the Truk Islands.
Cornered, the Combined Fleet is relieved by the arrival of a secret fleet of battleships and warships that were supposed to have been sunk as targets under the Washington Naval Treaty, including the battleship Tosa and the German ships that scuttled themselves at Scapa Flow.
Resurrected and transformed by the Magitek Research Department, these ships and weapons are Japan’s new hope against the otherworldly invaders.
Rise, scuttled fleet!

Yan Qing has survived first contact, alien politics, and falling in love with the most dangerous man on the planet. Settling down should be the easy part.
No, far from it.
Life in the Teleopean palace is full of quiet misreadings, cultural collisions, and the kind of danger that arrives dressed as diplomacy. When the Mys civilization appears at Amoro’s doorstep, their interest in Teleopea quickly turns personal. Their society runs on hierarchy and slavery. Their prince does not understand the word boundary.
As Yan Qing’s connection to the Ultimate Weapon deepens and an unknown voice begins reaching into his mind, peace slips further out of reach.
Falling in love was only the beginning.
Staying alive together is the harder part.

Summary
Hey, Say Again Sagan (Big Boy Writer) here.
Soooo, this is a story that MinorSmile09 / CoolGuyWrites and I wrote quite a while back, and we were originally going to first publish this as a physical book.
However, life got very busy on both of our ends, and we (me, this is pretty much my fault) just never got around to doing it.
However, we both decided that, for now, it would be best to just upload it here and then publish it as a book later.
Soooo... Enjoy this story, written a few years back, and please do tell us what you think of it!!
This is another long one, so there will be plenty of chapters!!!
And now, it's time for... FULL METAL 'MERICANS!!!!!Series

Summary
In a universe where every person awakens a Planet as the foundation of their power, the strength of one's civilization determines their might. From martial worlds where warriors reign, to mystic realms teeming with magic, to ethereal domains of immortal cultivators, every awakened Planet becomes a reflection of its creator's path.
But Alexander Sebastian is different. Reborn with memories from a modern, Earth-like world, he forges something never seen before: a Technological Civilization. While others summon Qi, Mana, or Spiritual Power, Sebastian builds factories, launches satellites, and commands fleets of starships.
With logic as his weapon and science as his foundation, Sebastian begins to shake the very foundations of this Supernatural cosmos. When a Star Destroyer punches through planets and dimensional weapons turn worlds into nothing more than paper, even the proudest civilizations must bow before the cold, unrelenting force of progress.
Witness a tale where science defies fantasy, and technology becomes the ultimate path to dominance.
