The protagonist transmigrates into the body of the son of a marquis in another world, inheriting the marquisate's title, developing the marquisate's territory, leading surrounding nobles, fighting against his own kingdom and neighboring countries, and ultimately becoming a grand duke. The protagonist has no system, no special abilities, and no harem; he conquers the world solely through his 21st-century knowledge and millennia-old Chinese military wisdom.

A blood-stained contract, a mountain of gold waiting to be mined, a precarious kingdom. He is an engineer, a foreman, the last hope of all the oppressed. He is an ambitious man, a capitalist, the most unstable piece on the chessboard of the nobility. In his left hand is a blueprint for overturning the world, in his right is the soft hand of his daughter. Vand, no, Edwin VanCleef, will use steel and concrete, gears and levers, to reshape the order of this world. "Truth lies only within the range of siege guns. And I am responsible for defining that range."

Jody, a science whiz, is transported to a world of magic and martial arts, but the magic he awakens seems to be different from that of others.

You can sense fire element, are you a genius fire mage? But I can sense carbon, hydrogen, and oxygen element, and the fireballs I create are even bigger than yours.

You can sense the wind element and fly on it? But I can control air density and walk on air.

The First Alchemist of the Royal City: Why can you produce such a powerful explosion with just a jar of salt?

I'll tell you, I can separate sodium and chlorine elements and recombine them into simple substances.

What magic or martial arts can compare to my physics and chemistry?

Wu Liang transmigrates to a primitive tribe and gets a hundredfold return reward by binding himself to the tribe's leader at the start!

Faced with the onslaught of the Roland Empire's iron cavalry, they were not confronted with stone tools and wooden clubs, but rather with organized AK rifles and heavily armored legions.

While the rest of the world was still charging with swords and spears, his tribe had already taken up rocket launchers.

While the Imperial mages were still chanting fireballs, they had already boarded their magic-powered mechs!

Years later, the imperial princess asked curiously:

"Wu Liang, who exactly are you?"

Wu Liang looked at his clansmen scattered across the world and smiled calmly:

"Me? I'm just a messenger of the spark of civilization."
