"Emperor's arena?" Yan Moshan was astonished. He clearly found the name unfamiliar. This was the arena for the Imperial Martial Conference, said to be a treasure handed down by the Great Yi Dynasty as decreed by fate, used only once every three years for the grand event. It was rarely utilized on normal days. Having been passed down for thousands of years, it was commonly referred to as the Imperial Martial Arena. As for the esteemed name of the Emperor's arena, it was seldom heard of.
