Without evidence, they can't just arrest people willy-nilly.
Therefore, Wei Zhi asked her, "The items Bai Qi took with him back then..."
That was the only evidence that could potentially convict everyone involved in the case. Without it, they would have to start the investigation all over, and the amount of manpower and resources that would be consumed is untold, not to mention the uncertain outcomes.
Hearing him say this, Ms. Liu's shoulders slumped in resignation.
She had anticipated this, but once Wei Zhi confirmed it, she couldn't help feeling disappointed.
After a pause, she said, "One of the servants who fled with Qi'er managed to survive, his name is Erji. But I can't hand him over to you just yet. If one day you can bring the mastermind to justice and need a witness, I will hand him over."
"And the items?"
That was what mattered most.
Ms. Liu shook her head and said, "I've been searching for them all these years."
