Fortunately, Gao Xiaotian was fairly decent to her, so the little girl did not end up crying and wanting to leave.
Meanwhile, Chen Kai had already decided to start executing their plan.
Before this, he had discussed with Song Taojie for several days in a row, ensuring that their plan was foolproof. Chen Kai knew that there was only one chance for this kind of thing; once it was thoroughly investigated, there might be no way to find that child again.
If the Gao siblings realized he had ulterior motives, they would surely become more guarded against him, and at that point, any action he took would be extremely difficult.
Chen Kai certainly did not want that to happen, so he patiently rehearsed with Song Taojie for several days. The process was utterly tiresome and boring; Chen Kai even felt it was quite stupid.
But there was no other way, everything was for the sake of seeing his child.
