The heart is worse than the action, Chen Feng immediately decided to start with the carpet: "Shui Bin, should we try to lift the carpet and take a look?"

"No problem~" Hongshui Bin opened the carpet according to Chen Feng's suggestion. The two of them rolled up the carpet and piled it in the corner of the wall, and then re-observed the ground covered by the carpet.

At this sight, they immediately noticed a different place. Under the sofa in the center of the room, there was a piece of floor that was different from the surrounding ones. There were obvious signs of separation around it, and it seemed that it could be opened.

As soon as he saw this special wooden board, Hongshui Bin knew he had found the right place: "Haha, I found it!"

"Well, let's lift the board, and be careful not to make too much noise." Chen Feng also smiled, and this time he didn't run in vain, and finally could catch Nangong Ao's feet.

The two moved the sofa first, and then lifted the wooden board with the screwdriver in the toolbox nearby, and a hidden door appeared in front of them.

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

There is a turntable on this secret door, which should be used to open the secret door, but Chen Feng did not dare to try to open it easily, because he didn’t know if Nangongao did anything with this mechanism. If they If the rash attempt fails, Nangong Ao will be reminded about it.

The two men were frowning at the agency. They didn’t know how to twist to open the secret door. This problem bothered them and made it difficult for them to take action. A Qiu is likely to be locked underneath. Whether the secret door can be successfully opened is the success of the action. key.

Hong Hung Bin stretched out his hand to knock on the secret door and felt the return force from his fingers: "This door is at least five centimeters thick. It is made of steel and cannot be forcibly opened by manpower."

Chen Feng threw a rat trap, and turned to the room to find out if there was any record of how to open the secret door: "Don’t be reckless. We must figure out how to open the secret door before we can do it. Otherwise, if Nangong Ao discovers him, we will not only find him. Evidence of killing the owner of the family, even Ah Qiu's life would be in danger."

It was difficult to get to the sky if Nangong Ao left us with clues, and it took a lot of time for Chen Feng and Hongshuibin. If they continue to search like this, it is estimated that they will not be able to open the dark after Nangong Ao comes back. door.

"You can't go on like this anymore. A dead horse is a living horse doctor. Let me try it!" Chen Feng gave up on finding a way to open the secret door, and got down and pressed his body in front of the secret door.

"Don't try it! It's very likely that something will happen!" Hongshui Bin anxiously grabbed Chen Feng's left hand. Who knows if Nangong Ao has done anything with the secret door, it would be unwise to make a haste.

Chen Feng smiled slightly, stretched out his right hand and blinked at Hongshui Bin: "Don't worry, I won't touch the turntable, I have another idea."

Chen Feng knocked **** the secret door with his fingers, and raised the volume as much as possible and shouted: "Aqiu, is it you down there? We are here to save you. Can you tell us how to open the secret door?"

Shushuibin was startled by Chen Feng's sudden roar, and quickly covered his ears with both hands, and said nonsense, "You are too nonsense. How could Aqiu know how to open the secret door, even if she knew it?" How can I tell you."

With the thickness of the secret door, it is difficult for the voice to pass. A Qiu below Chen Feng’s shouting here may not be able to notice that there are insurmountable obstacles to the communication between the two sides, so Hongshui Bin thinks Chen Feng’s approach is impossible. success.

"Try your best, it's better than doing nothing." Chen Feng continued to stick to his own approach. No matter what, he must have a clear conscience. If A Qiu is below, he will definitely respond to his cry.

Seeing that Chen Feng was so serious, Hongshui Bin no longer affected his shouts, but quietly went to the other side of the secret door and lay down, stretched his ears to hear if there was any response. Since he came here, he also wanted to contribute his own. A force.

Chen Feng shouted four or five times in a row, until his voice was about to smoke, and then he stopped and put his ears to the secret door with Hongshuibin, praying that the people below could hear his own voice.

"No matter what response you make! Please!" Chen Feng's heart was thumping wildly. Now he has no way to open the secret door, only expecting the people below to give him a hint.

The two held their breath, and finally heard a knocking sound from under the secret door after half a minute. It should be the people below who heard Chen Feng's shout and responded!

"There's a show!" Chen Feng and Hongshuibin looked at each other excitedly, and immediately pressed their ears for fear of missing any details.

The knocking sound from under the secret door was prioritized and stopped after a while, sounding like a reminder.

Chen Feng silently wrote down this voice, and imitated it on the floor with his fingers: "Hum! Duck! Duck!"

This percussion sounds a total of seven strikes, and there are two intervals between the seven strikes, and then the cycle repeats.

Hung Hung Bin noticed that this knocking sound had a special meaning, but he didn't know how to decipher it: "This should be the way to open the secret door, but what does it mean?"

"Hum! Deng Deng! Deng Deng Deng!" The percussive sound from the bottom still came. Obviously, the other party felt that the news contained in it was very important, so he insisted.

Chen Feng pondered various meanings, and suddenly had a guess, perhaps the changing percussive sound was reminding him of the way he twisted the turntable.

Chen Feng told Hongshuibin what he thought, and Hongshuibin immediately agreed. What is more important than opening a secret door at the moment? Since the people below insisted on spreading the news despite the poor communication, thinking about it, they should not escape the secret door.

Putting his hands on the turntable, Chen Feng raised his head and looked at Hongshui Bin. Whether or not they can decipher the percussion sound can be rescued by the people below, Chen Feng has no bottom in his heart and wants to seek the support of Hongshui Bin.

Hongshuibin gave Chen Feng a firm look: "Just do what you want, we can't open the secret door anyway, it's better to try, there is still a chance."

"Well, I hope I can't be too wrong." Chen Feng licked his lips and finally started to turn the turntable on the secret door.

Since the percussions below are very regular, Chen Feng resolves it into three pieces of information, one quarter turn, one half turn and one full turn. Fortunately, the turntable can only rotate counterclockwise. Chen Feng There is no need to consider the question of direction.
