When Su Bei heard this, a faint smile appeared on her face. "Since you mentioned evidence, Assistant, please tell Miss Tang the evidence."
The assistant took two steps forward and said, "After buying the supplement at the mall, I bought other things according to the old man's request and went to a nearby place to do some work. Therefore, I didn't take the supplements with me after buying them. I handed them to the mall staff to be packed and sent to the Tang family. The process of packing and delivery was recorded by surveillance cameras.
"After the items arrived at the Tang family, Madam personally opened them."
After saying that, he retreated to Old Master Tang's side.
Su Bei continued and asked calmly, "So, are you going to cast your suspicions on the mall this time and ask the staff to cooperate with the investigation?"
