South of the Seven Color City lay a vast expanse of southern slope.
This southern slope was a frequent training ground for Seven Color City's Soul Pet Masters. Further south, distinct mountain ranges appeared, stretching endlessly and forming natural barriers that completely separated human and Soul Pet communities.
One of the major hidden threats in the Western World, the Leopard Tribe Village, lurked in this mountainous area.
Over the past few decades, the Leopard Tribe Village had occasionally caused disaster, with its scale generally reaching the fifth or sixth-level tribes. In recent years, the Leopard tribe had become more aggressive, and seventh-level tribes had appeared several times within a few years.
This level nine species disaster was the largest in decades.
