Ouyang Ping took the hammer from Master Yan's hand and knocked it heavily on the floor three times: "Knock-knock-knock." ”

Immediately afterward, there were three more voices from under the floor: "Knock-knock-knock", this time much louder than before.

Ouyang Ping knocked twice more.

Two more responses from under the floor.

The entrance to the chamber is just below the floor, and there are people inside.

Zuo Xiangdong and Liu Wenbin dragged the paralyzed Elder Zhizhen to the front of the screen—Zhizhen sat on the floor.

"True, where is the entrance to the secret room?"

Zhizhen raised his hand and pointed to the right side of the curtain.

"Drag him over and let him drive on his own."

Left to the east and Liu Wenbin dragged Zhizhen to the right side of the door curtain, there is a lattice window on the right side of the curtain, and between the door curtain and the lattice window, there is a wooden wall about two meters wide.

Zhizhen supported his body with one left leg, and his right leg fell tremblingly on top of him, his toes resting on the floor.

Everyone's heart is in their throats.

Ouyang Ping and his comrades-in-arms have worked hard and finally seen the results today.

Zhizhen pressed his right hand on a circular relief, pushed it to the right, and the circular relief shifted two or three centimeters to the right. At this time, Zhizhen's hand still did not let go, he turned his wrist and pressed the counterclockwise to turn the relief, and soon, the circular relief began to do counterclockwise turning.

Immediately afterwards, the screen and the floor under the bonsai are separated in a concave and convex shape.

One centimeter, two centimeters, three centimeters. A concave and convex opening gradually unfolds.

Ouyang Ping, Liu Dayu, Staff Officer Li and Master Yan squatted on the north side of the cave entrance to carefully observe the situation at the cave entrance.

No wonder the sound of the hammer hitting this piece of the floor was so real, it turned out that the floor was only a part of the secret tunnel mechanism - there was a wooden board about ten centimeters thick underneath the floor, and the floor was attached to this wooden board about ten centimeters thick.

The entrance of the cave is getting bigger and bigger, Ouyang Ping wants to see people, but unfortunately there is a black rumbling under the entrance of the cave, so it can be seen that the sound of response under the floor is not under the ten-centimeter-thick wooden plank, the sound source may be in a deeper place, in Ouyang Ping's opinion, there may be a door under the entrance of the cave.

The secret door slowly hid under the wooden wall. Hidden in half of the place, it came to an abrupt end, and a concave and convex hole 80 centimeters long and 90 centimeters wide appeared in front of everyone.

Yan Jianhua rolled up the door curtain and fixed the curtain at a height of 1.5 meters with a rope, so that the light in the room was brighter.

Ouyang Ping and Liu Dayu walked to the door and looked towards the corridor, and the two of them finally understood: the corridor was paved with floor tiles, which were about twenty centimeters higher than the indoor floor, and the secret door was hidden under the floor tiles.

Who would have thought that the entrance to the secret room would be placed inside the door and the secret door hidden under the floor tiles of the hallway? It would be even harder to think of by placing a screen and two bonsai above the secret door.

Han Lingling took a cover lamp from the incense case, and Li Wenhua took out a lighter from his pocket and lit the lamp - everyone forgot to bring a flashlight. Fortunately, one light is enough.

There may also be a light in the chamber.

Under the light, a stone staircase appears in front of everyone's eyes.

"Zhizhen, how many people are down there?" Ouyang Ping looked at the chaff who was sifting the chaff and said sharply.

"Two people."

Ouyang Ping and Liu Dayu looked at each other for a moment.

"Which two?"

Zhizhen's back was against the wooden wall, like a pile of mud that could not be pasted on the wall.
