“Young master, the Zhao family’s young master faked an illness and went to future young miss’s place for treatment. . .” said a servant.

“Break his legs! Fail his organs! A fake illness? I’ll make him sick completely!” A man said.

“Yes! But young master. . . what are you doing?” The servant said, confused.

The man finished swallowing a bunch of expired pills and said, “I’m sick, gotta go find my wife for some treatment!”

Fu Hongxue was a cripple, born with a lame leg and subject to epileptic seizures. He was also one of the most powerful, legendary figures of the martial arts world, with a dull black saber that was second to none. His fame made him a frequent target of challengers, but whenever his saber left its sheath, only corpses would remain in its wake. One day, however, Fu Hongxue rescued someone whom he should have killed…and in doing so, set of a chain of events and a conspiracy that would rock the world.

A skilled but unfortunate modern-day assassin was killed in a freak accident. However, he soon found himself summoned to another world by an evil wizard, who had him possess the body of a boy as an experiment. After successfully planning the evil wizard’s downfall, he used the wizard’s body as a springboard to gain influence and power in his new world.
