"This."
Qian Wanyu took a glowing green Formation Stone out of her storage space. It was the very stone Ninth Sister had used to impersonate the Elf Heart.

If it left them alone, you might think you'd guessed wrong and stop investigating what happened before. Then it could keep causing you more and more trouble and even find a scapegoat to take the blame. Why wouldn't it?"

Dongfang Minghui took the bundle
