Right now, explaining the concept of a space bag or item, was the farthest thing on Xu Hu Zhe's mind. He trusted Xu Zeng to explain the concept of the space to Bai Mo in his own time. For now, their immediate priority was to reunite with Xu Zeng and 'assist' him in dealing with the bandits.
Xu Zeng wasn't in good condition when they were all together last. He seemed to be handling himself well, but seeing was believing.
With a brief word of caution to Bai Mo, Xu Hu Zhe steered the ox cart in the direction of the commotion. Though it might have been quicker to go on foot, he chose to bring the cart along, recognizing its potential usefulness in the face of Xu Zeng's past violence.
The ox cart rattled along the uneven path, jostling Xu Hu Zhe as he spurred the beast forward, Bai Mo clinging to the edges with all his might.
