In the Jiuxiao Continent, martial arts is respected. The weak are like ants living in the ruins of dark alleys, while the strong are like dragons roaring and gathering at the top of the clouds. The laws of this place use blood as ink and bones as inkstones. A three-foot-long sword can split the sun and the moon, and a murderous thought can stir up a bloody wind. There was once a drunk madman who trampled eighteen royal cities to pieces. Wherever the sword pointed, thousands of miles of mountains and rivers were dyed red. There was also a saint who lowered his eyes to calm the nine thunder tribulations, and with a flick of his sleeves, a golden lotus suddenly appeared in the abyss.
