Zhang Bin and his two companions hadn't gone far, as Duo Duo was still exploring deep underground.
Duo Duo couldn't use Earth Escape, so it burrowed through the ground like a drill, constantly rotating to advance. As a result, its speed wasn't particularly fast, but its endurance was incredible. This was something that even cultivators and Superpower Users who had mastered the Earth Escape Technique couldn't hope to match. Its exploration range of thirty kilometers was also something no cultivator could rival.
Deep underground, Duo Duo found a golden ox of immense value, confirming that the City of Gold was indeed hidden deep within the desert. The exact location, however, still required careful exploration.
Therefore, Zhang Bin and his companions would not leave under any circumstances. To do so would be tantamount to handing the City of Gold over to the Americans on a silver platter.
