Brief introduction of vault martial arts

Dome Wu, one of the characters in the series of stand-alone games of Legend of the Sword and the Chivalrous Man, once appeared in Legend of the Sword and the Chivalrous Man. The vault is an ancient dragon, which performs the duties of cloud and rain. People trapped in Loulan city died because they couldn't bear to lack water, and it rained privately, so they were banished to the world by heaven.
