Starting with a Body Full of Kung Fu, I Fought My Way from Slave to Lord

[Ensemble cast, alternate history, warlords and shifting alliances, no System, no info-dumping at the start, multiple storylines, vast worldbuilding]

What is the martial world? Is it flashing blades and punches that land with a thud? Is it loyalty and honor, boldness and ambition?

Zhao Dong never figured it out, and now he doesn't need to!

Why?

After transmigrating to another world, martial arts? They're nothing more than a bit of brute strength.

True masters wield vital energy.

There is no order in this otherworld. Warlords wage war, feudal lords carve up the land, the victors rule, and the defeated die.

Others transmigrate as kings with a System of their own, but Zhao Dong becomes nothing more than a slave.

With nothing but hot blood, a clever mind, a resolute heart, the martial arts of the Southern School, and just a little luck, he somehow rises from slavery to become a warlord commanding the strongest domain.

An ordinary person's path is paved with corpses and carried on a back burdened by blood feuds, as they claw their way out of a heap of the dead.
