"The money he spent is not from my Celestial Empire, and he should get a little back. "His lady's method of slaughtering people must be unusual, I don't know if the silver brought by Xiyu Sheng is enough?

"I've renovated all the private rooms in the Wind Pavilion, and even if no one is secretly watching in the future, I can hear their conversation clearly. ”

In the past, it was not just the girl who found out the news, the women in Tingfeng Lou have undergone special training, whether it is skill, observation of words and colors, hearing, and smell, they are all good hands, but there are still many omissions when the guests enter the room, mother...... How did Leave Childe to do it. He was a little curious, even if this little cat had good hearing, it was impossible to hear what the people in all the rooms were saying? Not to mention that if a dignitary was talking about something important, he would let people put their hands on guard, even if he had many masters against the sky, he couldn't arrange people to monitor every room at any time!

"Let's go, I'll take you to see ......" After speaking, she took Tang Haotian's hand and came to a small room on the third floor, which was full of items like cups, and thin copper wires were hanging on them.

"Lady, what the hell are you doing?" he was a little confused, could he just rely on these little copper cups to know what others were saying?

"If you call it wrong again, you will not be allowed to eat at night. Li Kexin pouted and walked to the door and buckled the door panel: "Do you hear the sound?"

"It's so loud that you can hear it unless you're deaf. Tang Haotian told the truth.

"That's right, I did this with scientific evidence, it has been proved that solids can conduct sound, but in the process of propagation, the sound will slowly weaken, and the distance is naturally inaudible, among all the metals I can find, copper has the best sound transmission, it is transmitted through the principle of sound wave vibration, just like knocking on the door.

I have placed several things similar to copper wind chimes in each room, one is decoration, which plays a beautiful role, and the second is that it plays the role of solid sound transmission, as long as the people in it speak, no matter where they are in the room, it will definitely be transmitted to this message room through the copper wire on the copper wind chimes, so as to know what they are saying. She felt that her explanation was very detailed, but it was still confusing to hear it.

"What is the scientific basis, and what is the proprietorship?" he really didn't understand!

"It doesn't matter if you don't understand, you know that you can know all the news about the private rooms here. She really couldn't explain to Tang Haotian what scientific basis was.

"Ligongzi is so powerful, this kind of method can be thought of. He patted the ass at the right time, hoping that the sharp-toothed kitten would forgive him for the slip of the tongue.

"Of course, since I have taken over this green building, I will do it well. "Not only can you inquire about the news, but you can also make money, so why not?

"Okay, I'll wait to see how Gongzi Ligong makes this Qinglou impressive. "Tingfeng Pavilion's business has been booming in the past, and after her such a hard work, business will definitely get better and better.

"When it opens here, they will know, whether it is the layout of the wind building or the newly rehearsed singing and dancing, they have never heard of it, and they will naturally come when the time comes. "She knows that the girls in Tingfeng Pavilion are all performing arts and not selling themselves, but it is not easy to attract guests just by relying on piano, chess, calligraphy and painting, singing and dancing, so she can only come with strange tricks to make those people feel fresh and interesting, and guests will come often.
