Qin Mo's visit to Yang Xiao this time signified a major change, likely due to some things the middle-aged man whom Yang Xiao had saved had told him.
For instance, the respectful title Qin Mo used for Yang Xiao. Before, even though Qin Mo had asked for Yang Xiao's help in saving someone, he hadn't used the formal "you" to address him, but now, he not only used "you" but even knew to call him Mr. Yang.
Therefore, when Yang Xiao heard Qin Mo speak, he couldn't help but be startled for a moment.
Afterwards, a smile crept onto Yang Xiao's face, giving off the impression of an elder who sees their younger relative as a promising student worth teaching.
However, the smile on Yang Xiao's face soon faded, and he looked somewhat stern.
