Although Miao Ying called a group of policemen to the scene, she did not ask them to take Xie Tongguo's uncle to the police station. Instead, she just asked him for more detailed information about Xie Tongguo.
After that, the police searched the house. Although the house had not been renovated since the sale, none of Xie Tongguo's personal belongings had been found. It seemed that Xie Tongguo must have thought of all of this in advance, eliminating any trace of himself or his belongings.
As such, they assumed that he had done the same thing in his basement. And, just as they thought, when they searched the dusty basement, they found nothing important, only old, useless stuff.
For this reason, Cui Lizhu was seriously annoyed at Zhao Yu. She felt like the search had been an unnecessary waste of her time and skills!
