Three years ago, a grievous news came from the distant stars, Crown Prince Ryann died so heroically on the frontier that even his remains couldn’t be found and returned home.
The Empire has lost its handsome and dazzling prince, as well as one of the strongest new crystal human beings in this century.
It was said that the prince left a poor widow behind.
… At the funeral, the young widow had black hair and white skin. He lowered his head in silence as he held the coffin.
The royal family and high-level officials of the empire couldn’t help frowning greatly: The person who made His Highness fall in love during his lifetime was actually such a vulgar creature.

Jiang Jianming worked like a salted fish in the imperial military academy for three years, and he was unremarkable to the extreme.
In the graduation season, he calmly rolled up his baggage and stepped into the cruel distant star battlefield to collect the body of His Highness.
Everyone knows that disabled humans are weak, and they have no fighting ability at all. How many people either sneered or regretted, just waiting to wrap the corpse of this young man who had exceeded himself?
Until later, the pale young man scoured the scorched earth covered in blood, and when he raised his hand, the sound of gunfire broke through the long night. The Milky Way was reflected in the bottom of Jianming’s eyes, and the blade of the mecha was bathed in crystal and starlight.
Behind him, countless new human beings were convinced by this ‘proud son of heaven’, and they all called him “commander” in unison.
The alien creatures were frightened and trembling;
The rich and glorious dominion star-lord treat him as a guest;
The mu*derous space pirate love and hate him…
Jiang Jianming smiled slightly: “Don’t be so exaggerated, I’m just a weak and sickly disabled human being.”
Imperial people: “?”
So when the monarch came back from hell to the world, facing the legendary story that his lover had turned the distant star upside down for him, the monarch raised his eyebrows coldly: “Nonsense. The commander is just a weak and sickly disabled human being… Tell me, who encouraged him into a mecha today?”
Imperial people: “???”
—Please light the withered years, go through the remnants of the old civilization and the cold stars, and wake up in my arms before the dawn of mankind.
Then there's Supremacy Games, Overgeared, reincarnation of the strongest sword god(closest probably to this novel, but shtty quality). Pretty much all the popular ones. Though I mostly rec TLM.
