Unfortunately, after the detective fled with the notebook, he vanished without a trace.
Song Zhen wanted to get that item all along, but could only be anxious about it.
Since this matter had no concrete result, he was at a loss as to what to tell Qiao Yi, lest she also start overthinking.
Song Zhen guessed that it was possible Cassie had laid a net, and the detective, fearing Cassie's local influence, was in hiding.
After Lu Xunzhi learned of this, he also organized a team to expand the search around where the detective last spoke with Song Zhen. So far, they've found nothing.
Thus, unbeknownst to Qiao Yi, both Lu Xunzhi and Song Zhen were working hard for her to uncover the truth about her biological father's death. The promise made to Qiao Yi, to keep investigating, was not an empty word.
And now, Cassie was indeed pursuing Qiao Yi, even following her to the highway service area.
