When Master Na Wu heard this, he immediately smiled, waved his hands and said,

"Xiao Yang, what are you thinking about? This is the refuge of our Nalan family. Why set up a trap?"

"Old man, you'd better go down with me and have a look. I don't know how to close this mechanism yet."

Naturally, Yang Jun couldn't let him go.

Although you cannot punish others with evil, you still have the necessary guard against others.

Master Na Wu saw that Yang Jun didn't believe him, so he sighed: "Forget it, I'll take you for a while."

After saying that, he squatted directly at the entrance of the cave and touched inside with his hand. The dark entrance of the cave suddenly became bright.

Na Wuye went down the stairs, then pointed at the two buttons next to the entrance of the cave and said,

"The one on the left is the light switch, and the one on the right is the switch that opens the secret room."

After that, continue walking down.

Yang Jun didn't have time to check the two switches, so he could only follow him and continue walking down.

"The secret room is closed from the inside. Even if people outside know the mechanism that opens the hole, they will not be able to open it unless the hole is blown open."

Na Wuye introduced as he walked.

When Yang Jun heard this, he realized that this mechanism was really powerful. If it was closed from the inside, no one from the outside could get in.

He couldn't help but sigh that the wisdom of his ancestors was really invincible, and he could design all kinds of mechanisms.

In the courtyard where he originally lived, the mechanism was set on the stone table in the courtyard, but this mechanism was actually set on the blue bricks of the wall.

If Master Na Wu hadn't led him, he probably would never have known the entrance to the secret room in his life.

The cave is very narrow and can only accommodate one person bending down to pass through.

The cavern leads diagonally downward. Fortunately, the caveway is not long, about twenty meters or so.

After walking up the stone stairs, the two came to an empty stone room.

Yang Jun looked back at the cave and guessed the distance between the stone chamber and the ground. The vertical distance was about eleven or two meters.

This stone chamber is more than four meters high. Excluding the floor height, that is to say, the ground is about seven or eight meters from the top of the stone chamber.

Yang Jun took a breath.

He couldn't imagine how difficult it was to build this stone chamber and how much it cost.

Yang Jun looked at the entire stone chamber.

The overall feeling given to him is in one word, big.

The stone chamber is very large, about five to six hundred square meters, almost equivalent to surrounding the entire backyard.

In the middle of the stone chamber stand eight stone pillars that are hugged by three people, seemingly distributed according to the principles of Tai Chi and Bagua.

The top, bottom, left and right of the stone chamber are covered with blue ceramic tiles, which feel cold and slippery to the touch.

There is an oil lamp device on the wall every few steps, which is a backup setting to prevent power outage.

Yang Jun stayed inside for a while, but he didn't feel dull at all. He could faintly feel the wind blowing.

Yang Jun looked for a long time and still couldn't find where the vent was, so he asked.

"Old man, is there a vent here?"

"Yes, I have."

Na Wuye took two quick steps and came to the corner of the stone room, pointing at the small black round holes above his head.

"These tunnels connect the eaves of various houses. It is difficult for ordinary people to find them unless they climb up."

"Incredible craftsmanship!" Yang Jun exclaimed.

"of course!"

When he mentioned this, Mr. Na Wu was very proud and said proudly: "Xiao Yang, I'm not bragging to you. It took more than two years to build this secret room, and it was specially designed by a master craftsman from the Ministry of Engineering.

.”

When Yang Jun heard this, he couldn't help but click his tongue.

Fortunately, it is the Nalan family. If it were left to ordinary people, let alone hiring a master craftsman from the Ministry of Works to design it, the construction cost would not be affordable for ordinary people.

"Old man, the more you say this, the less likely I will let you redeem this house." Yang Jun said with a smile.

After hearing this, Mr. Nawu smiled and waved his hands and said,

"Don't do what he wants. Besides, I don't have the money."
