There are more than a dozen bamboos on the wall, which look like disposable paper cups, the size is about the same size as a paper cup, Lu Yijun is a little puzzled, "What is this for?" ”

He took it down and looked at it.

There are still threads in more than a dozen bamboo tubes, and he can take the cups off the wall with a light hand, but there are still threads connected to the back, leading to the wall, and he doesn't know where it leads in the end.

He seemed to have thought of something, but he was a little incredulous, "Ah Shu, you shouldn't be ......"

Xu Shu nodded, confirming his guess.

"Originally, I was afraid that the guests on the second floor would not be able to hear the sound on the stage, so I specially made this kind of device, but later I found out... It's a great bugging device, don't you think? ”

At first, she just wanted to solve the situation that she couldn't hear the sound of the audience upstairs, so she meditated for a while, and thought of the game she played when she was a child, as long as she connected the line between two paper cups, she could hear the words of the companion on the other end, which was directly applied by her.

"Could it be that the thread of these cups leads to ...... in the end?"

"Don't doubt it, it's the downstairs room."

Lu Yijun suddenly felt a chill down his spine, "Then what device did you use to record?" ”

Xu Shu added a dish of chopsticks and put it in his bowl, "There is a decoration in each room, which looks inconspicuous, but the sound effect is still very good." ”

Lu Yijun broke out in a cold sweat, and couldn't help praising her, "Amazing, really amazing." ”

The wine table, the gambling table, and the bed are the places where people are most likely to leak their secrets, and as long as Xu Shu asks someone to listen downstairs, he will inevitably be able to grasp the secrets of the entire Nancheng dignitaries within a few years.

Xu Shu seemed to be able to see what he was thinking, and explained: "I don't have that much ambition, my original intention is just to test this method and tell you." ”

Lu Yijun was a little puzzled, "Tell me?" ”

"Well, you have your own secret guards, they have their own codes, they have their own system, I will send you another set of listening equipment, is it twice the result with half the effort?"

Lu Yijun stayed for a long time, sitting in his place, and he didn't know how to take the chopsticks in his hand.

He swallowed hard, "You... When did you come up with this? ”

Xu Shu twisted his neck, "A few days ago, but because I don't know if the effect of this method is good, I haven't told you, I dealt with it myself a few days ago, and then improved it, and tested it in the first floor of my world for a few days, and found that as long as the distance is not very far, it can be done, of course, if it is too far, it will not work." ”

Lu Yijun didn't even have the mood to eat for a while, all he wanted was to hurry back and deploy his eavesdropping team.

Several countries are planted everywhere, but it takes time to cultivate, and generally if it is not cultivated from a young age, no one dares to appoint it easily, because the most important thing is to be heartfelt.

It would obviously be unwise to pin all your hopes on trusting people's hearts, and the method Xu Shu gave him was simply a send-off.

"Don't worry, it's not like this for a while, and today is Chinese New Year's Eve, our tradition should be to watch the Spring Festival Gala."

Lu Yijun: "Clams? Spring Festival Gala, where to watch? ”

Xu Shu raised his chin, "Well, I'm about to play." ”

Don't worry about me.
