Heart is not as good as action, Chen Feng immediately decided to start on the carpet: "shuibin, or we try to lift the carpet to have a look?"

"No problem ~" according to Chen Feng's proposal, Hong shuibin lifted the carpet and piled it up in the corner of the wall, and then observed the ground covered by the carpet again.

At this time, they immediately found a different place. In the center of the room, under the sofa, there was a piece of floor that was different from the surrounding ones. There were obvious signs of split around it, which should be able to be lifted.

As soon as he saw this special board, Hong shuibin knew that he was looking for the right place: "ha ha, I found it!"

"Well, let's lift up the board and be careful not to make too much noise." Chen Feng is also happy, this time did not run in vain, finally can seize Nangong Ao's horse feet.

They first moved the sofa away, then tilted the board with a screwdriver in the toolbox next to them, and a secret door appeared in front of them.

Chen Feng thought that after lifting the board, he could see the hidden area below. However, he saw another closed door in front of him. Nangong Ao was too careful and took so many protective measures.

There is a rotating turntable on the secret door, which should be used to open the secret door, but Chen Feng is afraid to try to open it easily because he doesn't know whether Nangong Ao has done anything on this mechanism. If they try to fail rashly, will Nangong Ao be reminded of it.

They are worried about the mechanism. They don't know how to wriggle to open the secret door. This problem bothers them and makes it difficult for them to make a move. Ah Qiu is likely to be shut down. Whether the secret door can be opened smoothly is the key to the success of the action.

Hong shuibin reached out his hand and gently knocked on the secret door, feeling the return force from his fingers: "this door is at least five centimeters thick. It's still made of steel, and it can't be opened by human force."

Chen Feng turned her head to the room to find out if there was a way to record how to open the secret door: "don't be rash. We must find out how to open the secret door before we can start. Otherwise, if Nangong Ao finds out, not only can we not find the evidence that he killed the owner, but also ah Qiu's life will be in danger."

It's hard to find any clues that Nangong Ao can use. It also took Chen Feng and Hong shuibin a lot of time to find them. If they continue to search like this, they will not be able to open the secret door when Nangong Ao comes back.

"It can't go on like this any more. I'll try it!" Chen Feng gave up to find the way to open the secret door, lying down and sticking to the front of the secret door.

"Don't try! It's very likely that something will happen! " Flood bin quickly pulls Chen Feng's left hand. Who knows whether Nangong Ao has done anything on the secret door. It's unwise to rush out.

Chen Feng smile, stretched out his right hand to the flood bin blink: "don't worry, I won't touch the turntable, I have another idea."

Chen Feng knocked hard on the dark door with her fingers, and raised the volume as much as possible and called out, "ah Qiu, are you down there? We have come to save you. Can you tell us how to open the secret door? "

Hong shuibin was startled by Chen Feng's sudden roar. He quickly covered his ears with both hands and said: "you're ridiculous. How could ah Qiu know how to open the secret door, even if she knows how to tell you."

With the thickness of the secret door, it is difficult to pass the voice. Ah Qiu, who is under Chen Feng's shouts here, may not be able to notice that there are insurmountable obstacles in the communication between the two sides. Therefore, Hong shuibin thinks that Chen Feng's practice is impossible to succeed.

"Try your best. It's better than doing nothing." Chen Feng continues to adhere to his own practice, no matter what he has to do with a clear conscience, if ah Qiu is below, he will certainly respond to his cry.

Seeing Chen Feng so serious, Hong shuibin no longer affected his shouting, but quietly went to the other side of the secret door, stretched his ears to hear if there was any response. Since he came here, he also wanted to contribute his own part.

Chen Feng yelled four or five times in a row until her voice was almost smoking. Then she stopped and stuck her ears to the secret door with Hong shuibin, praying that the people below could hear her voice.

"No matter what kind of response you can make! Please Chen Feng's heart is pounding wildly. Now he has no way to open the secret door. He can only expect the people below to give him a hint.

Two people hold their breath, half a minute later, they finally hear the knocking sound from the bottom of the secret door. It should be the people below who heard Chen Feng's cry and gave a response!

"There is a play!" Chen Feng and Hong shuibin looked at each other excitedly and immediately pasted their ears for fear of missing any details.

The percussion from the bottom of the secret door was in order of priority and would stop at intervals. It sounded like a reminder to them.

Chen Fengmo wrote down the voice and imitated it on the floor with his fingers: "Deng! Push it! Go, go, go

There are seven taps in total, and there are two gaps between them, and then they are recycled.

Only when Hong Shui bin noticed the special significance of the percussion, he did not know how to interpret it: "this should be the way to open the secret door, but what does it mean?""Deng! Push it! Go, go, go The percussion sound below is still persistent. Obviously, the other party thinks that the information contained in it is very important, so he will insist on it.

Chen fengzhuo pondered over various meanings and suddenly had a guess. Maybe the changing percussion sound is the way to remind him to twist the turntable.

Chen Feng told Hong shuibin what he thought, and he immediately agreed. Now what is more important than opening the secret door? Since the bottom of the people in the case of poor communication adhere to the spread of news, think about it should be with the secret door escape relationship.

Put her hand on the turntable, Chen Feng looks up and looks at hongshuibin again. Whether the people below can be rescued depends on whether they can decipher the percussion sound. Chen Feng has no bottom in her heart and wants to ask for Hong shuibin's support.

Hong shuibin gave Chen Feng a firm look in his eyes: "do as you want. We can't open the secret door by us. It's better to fight and have a chance."

"Well, I hope I'm not too wrong." Chen Feng licked her lips and finally began to turn the turntable on the secret door.

Because the percussion sound below is very regular, Chen Feng dissolves it into three pieces of information, which are a quarter turn, a half turn and a full turn. Fortunately, the turntable can only rotate counterclockwise, and Chen Feng does not need to consider the direction.
