At this moment, standing behind the green ox, Xu Rigang, Huo Xing, and others like Chi Xiong and Zi Ying all had fiery expressions in their eyes.
The green ox did not hesitate and stepped forward to the foot of the mountain, in front of a huge stone wall.
This stone wall differed from the rugged mountain body, appearing relatively flat.
After approaching the stone wall, the green ox reached out his hand and began to continuously touch the wall.
It seemed like he was searching for something.
A moment later, he found a protruding part on the stone wall.
Next, the green ox immediately called out to Chi Xiong behind him:
"Chi Xiong, bring the item."
"Yes!"
Chi Xiong immediately picked up a large copper box from the side, walked forward, solemnly placed the copper box on the ground, and then retreated.
Zhou Yu curiously stared at the copper box, swept it with his Divine Sense, and found that he couldn't penetrate it at all.
At this time, the green ox looked at Zhou Yu again.
