As he walked out of the cell, Wen Ruchu kept thanking Zhang San incessantly.
Wen Ruchu was the eldest son and grandson of the Head of the Wen Family, not just the apple of his eye but also the future hope of the Wen Family. Although his attitude towards the people from Town Martial Office had been haughty, growing up in an environment like the Wen Family's, it was impossible for him not to have some arrogance and an understanding of human relationships and worldliness.
Added to this was the cultivation from the Head of the Wen Family, which made Wen Ruchu keenly aware of Zhang San's abilities.
So, while his mouth spoke words of gratitude, what he was actually hoping for was to use this opportunity to get closer to Zhang San.
If he could bring Zhang San under his command, that would be a great advantage for the Wen Family's future plans to extend their reach into the Town Martial Office.
