Rhino Horn Continent.
Without discussing the outcome of the confrontation between Cao Wenjin and the Golden-winged Thunder Eagle, let's focus on Zhouyang, who began mining in the Spirit Stone Ore, digging for seven to eight days straight.
During these seven or eight days, he worked for three hours and rested for one hour, maintaining this routine.
After such continuous excavation for seven to eight days, the tunnel he had dug had reached several thousand feet in length.
However, despite such prolonged digging, Zhouyang still had not found the Top-grade Spirit Stones he desired. He did uncover a considerable amount of Middle-grade Spirit Stones, likely over a hundred pieces when cut, and even more Low-grade Spirit Stones, at least four to five thousand pieces.
This harvest was certainly unsatisfactory to Zhouyang, as Rhino Horn Continent was currently no friendly place; each additional day he spent there increased the danger.
