Dominate the World with One Sword

"He was a weak scholar and became a slave. He became a disciple of a killer and avenged his parents. It was difficult to navigate the rivers and lakes in the light of swords and shadows. He lamented his bizarre life experience and it was difficult to track down the murderer. A slave became a generational hero! A killer became an emperor! With one sword, he avenges the enemy, wins the smile of a beautiful woman with one sword, and conquers the world with one sword!"
