I woke up to find myself, a glorious Soviet base vehicle AI, in a bizarre American wasteland—a place filled with atomic punk metal lumps and mutated giant cockroaches, even more outrageous than the heart of capitalism!

To restore order (and incidentally have some fun), I "recruited" a group of tribal natives who couldn't even put on their own pants. The most urgent task? Teaching them to speak magnificent Chinglish! After all, who can stand that incredibly complicated, unrelated native English?

And so, a bizarre sight appeared in the wasteland: a group of blond, blue-eyed burly men, speaking broken, construction-worker-accented English, shouting "Hurrah! For Ironhead God!", drove their magnetic tanks over mutants, followed by a swaying Kirov...

Hey, you over there, the shelter kid in the blue bodysuit, and those tin knights with laser guns, any complaints about the "Red Iron Curtain"? No? Very well, comrade, welcome to the Soviet wasteland!

Humanity has never been so close to the edge of destruction. If it does not fight, it will be destroyed. Only the Star Marines stand up. They are warriors blessed by the Emperor, the legendary guardians. They travel in the starry sky, guarding humanity for thousands of years. The storm is about to rise, and it starts from the Far East. Special note: The style of this book tends to develop towards "Gothic"...

[Invincible, Daily, Simulator, chat groups will appear in the early and middle stages. 】

As a result, every simulation of Bai Ye is a journey of salvation.

Early simulation, daily life.

After the chat group appeared, Bai Ye's good days were over, as he saw that everyone in the chat group was someone he knew.

The sage of the Mechanic Church, Exis.Σ.Σ.Lu (Lu for short), transmigrated to a "terrifying" place. Here, humans worship psychic energy and call the practice of cultivating it "cultivation of immortality." Here, a strange, demonic voice calling itself "System" whispers in Lu's ear from time to time. Here, there are also powerful psychic entities comparable to spatial gods and demons. How corrupt, how terrifying! But… the Great Sage is never afraid. The Great Sage is always thirsty for knowledge. This is a good opportunity to observe psychic energy and research countermeasures. Perhaps, he can even find his way home. As for joining? Impossible, absolutely impossible! The Great Sage, following Om Messiah and believing in science…

[System Message: World Line Initializing... Alteration Rate: 0.001%]

Su Li stared at the scene unfolding on the massive public monitor, a stream of curses catching in his throat. Of all the places to be thrown into, it had to be Island Iffish—right at the dawn of the One Year War. Was this some kind of cosmic joke? Was fate itself trying to get him killed?

But then he discovered a secret: he could alter the very fabric of this world line, reaping incredible rewards for every change he made. From that moment on, the legend of the "White Devil" was destined to be rewritten.

His enemies could only cry out in disbelief, "What in the world is that Zaku?!"

Su Li would just grin, his voice cutting through the comms. "Hey, Red Comet! You think you're three times faster? Then prove it and get over here!"

Eli, who came to the Universal Century, witnessed the cruelty of war. Driving a mass-produced machine, he wanted to stay away from the world of conflict.

But he never thought that the meteor of the new human in the battle really made him want to do something.

He wanted to change the tragedy.

Come and witness, the tears of another Universal Century

I came to space to realize my dream, but I was fighting pirates all day long. I wanted to retreat to the second line and become an instructor, and I started fighting with the Adjuster. Then I will show you what a regular army is, what is the real Federation ace, Gundam? Please understand, the Federation Army never wins by fighting alone.

My name is Su Qi, and I became a transmigrator by sheer luck. This is a world where everyone can raise a Familia. On the very day I awakened, the system asked me what Familia I wanted. But only children make choices; adults want them all! Zerg, Undead, Demons, Omnics, Skaven, Orcs, Grey Gu Storms, Abominations, and even ordinary humans? What, you say you fought your way through one of my Familias? Then congratulations, I have eight more Familias like that!
