After all, Big Ke and Ah Lu were elite mercenaries. The two of them quietly approached the room that Jiang Yao mentioned, and it took less than three minutes to control the two people inside.
A few seconds later, Jiang Yao received a message from Big Ke.
Only then did Jiang Yao return to her room and remove the bug. She was cautious when she did that as that thing was very expensive. If it was in her hands, she might be able to reuse it for other purposes another day.
Jiang Yao had to thank Lu Xingzhi for teaching her to recognize that coin-sized bug. Lu Xingzhi had once drawn Jiang Yao's attention to all kinds of high-tech eavesdropping tools that he had seen in his notebook. One of them was the one in her hands.
Therefore, there was no harm in learning more things. If someone did not know anything about the eavesdropping devices, even if they accidentally found one, they would think it was a child's toy.
