In this world, there is one place in each of the four directions where true energy is released. Each was occupied by one of the Four Clans. Ten thousand years ago, the Four Clans went to war, and humanity emerged victorious. The human race sealed away the true energy of the other three clans, then built dragon veins in the Central Plains to absorb the true energy of all four clans, leaving the other three with no hope of ever rising again. Ten thousand years later, all kinds of gangs and religious sects have sprung up among humanity, while strange phenomena appear throughout the world. One day, the imperial court announced that it would organize a gang war, with ten Rebirth Pills as the grand prize. Said to be relics from the ancient war, the pills can bring the dead back to life and transform the living from the inside out. Gangs and religious sects across the martial world are sharpening their weapons, eager to take part. Meanwhile, a new gang, the World's Number One Gang, has quietly risen to prominence. Is this an opportunity, or a conspiracy?
