Xu Duheng didn't answer, but slowly pointed to the empty place.

"Hold on to me."

Then the two jumped straight down, landed at the side window, and walked in lightly.

The inside of the ancestral hall was quiet, just like the last time everyone came together, there was no difference.

Xu Duheng glanced outside the door and explained in a low voice: "Didn't you hear a sound from a place last time?" Or Du Yue himself proposed to investigate this matter. ”

Qingdai nodded slowly, "I remember this incident, but didn't they all think it was a mouse at the time?" ”

Xu Duheng shook his head, "Follow me." ”

Qing Dai paused, glanced at Xu Duheng beside her, and fell into deep thought, "Then are we going to demolish someone's ancestral hall now?" ”

Xu Duheng couldn't help but poke Qing Dai's forehead, "What are you thinking about in your little head." ”

Qing Dai tilted her head and said, "How can I know if you don't say it?" ”

Xu Duheng raised his steps lightly and walked towards the back.

I only heard him boo: "Listen, there is a sound of breathing in here." ”

Qing Dai paused, her scalp tingling a little, "How is it possible." ”

As she spoke, she put away her expression of disbelief, and then slowly walked towards Xu Duheng, following his movements, and gently leaning her ear to the wall.

The people inside seemed to be able to feel the movement outside, and the subsequent breathing became one after another, a little struggling.

As soon as Qing Dai heard this, she immediately took a few steps back, covering the corners of her mouth and almost leaking out of her exclamation.

"How so?"

Xu Duheng gently rubbed against the wall, "I haven't found any mechanism yet, and I don't know who it will be in here." ”

Qing Dai looked left and right, "It should be a dark wall." ”

Qingdai gently knocked on the wall, only to find that the whole wall was hollow, but this kind of seamless craftsmanship can really be said to have no traces.

If it weren't for Xu Duheng discovering the movement here, no one would have thought about this aspect at all.

"Look around, the mechanism must be outside."

Xu Duheng said slowly: "There is nothing placed around this wall at all. ”

Qing Dai glanced at the wall, then turned and rubbed against the pillar.

"Strange ......"

Xu Duheng also followed behind Qing Dai and searched left and right, but the two of them searched for a long time, but they didn't find any flaws.

"This Du Qingqing is indeed not simple."

At this time, the sunlight outside the window was actually a little dazzling, which made Qing Dai's eyes squint at an inopportune time, and she held her forehead and looked out the window.

The ray of sunlight slowly hit the side of her face, "The light is quite strong today." ”

Qing Dai paused slightly, and slowly looked towards the light source in that place, and happened to see an amber translucent glass on the lintel.

Because only the light in that place is unique, a warm light, it is not much different from the sun, but it is because of this light that Qingdai looks at Xu Duheng.

Xu Duheng discovered what Qing Dai saw, and quickly jumped on the beam, observed it, and jumped down again.

"It's a glass brick that's a little loose."

Qing Dai pondered, and suddenly ran to the position of the table, not knowing what she was looking for.

Isn't this the refraction of light? There must be something in this room that is going to be used for this thing.

Qing Dai searched the room for anything that could reflect the light, and finally, she pulled out a small bronze mirror under the huge candle base.

But seeing this, the smile on Qing Dai's face was put away again, "But I don't know what to do if I don't know the angle?" ”

Xu Duheng didn't seem to understand what Qingdai meant, but he still followed her gaze and kept looking.

"Here's what to do."

Qing Dai didn't have time to answer, and it was because she discovered this that she felt even more wonderful, how could the people here know these principles.

And invent something like this.

Qing Dai had no choice but to explain: "I may have found the key." ”

"There's light, there's a mirror, wait a minute, there's a spot of light in a flash."

Qing Dai gently shook the bronze mirror in her hand, and just like that, a small spot of light hit the wall.

"Since this thing is here, it must have its effect."

Qing Dai explained this, and began to constantly change angles, towards the wall, and the spots of light swept around on it.

But she never found what she was looking for.

Xu Duheng stretched out his hand and took it, "Give it to me when your arm is tired." ”

Qing Dai frowned and said, "I don't have ......"

Before Qingdai refused, Xu Duheng had already taken it, raised his arm, and swept it towards other angles.

Qing Dai was surprised to observe that Xu Duheng seemed to have understood the law, and even clearly remembered the angle he had just found.

There is not even a single place of duplication.

Xu Duheng glanced at Qingdai, "Don't worry, we still have a lot of time." ”

Qing Dai nodded slowly, "It's okay." ”

Xu Duheng searched the wall all over but didn't find the place he was looking for, he paused for a moment, began to look left and right, suddenly he paused, and then gently raised his hand to reverse the bronze mirror, shining on the ground.

At a floor tile near the wall, I don't know what it was marked, but under the light reflection of the glazed bricks, three white spots of light appeared.

Qing Dai looked at this, and immediately asked Xu Duheng to stay still, she reached out to touch the three points of light, and with a light press, the floor tile actually clicked and dented a few inches.

Qing Dai immediately got up, stood still with Xu Duheng, and raised her eyes to the wall where there was no movement.

Soon, there was a sound of squirming chains inside, and Qing Dai looked at Xu Duheng with a happy face.

Xu Duheng stretched out his hand towards Qing Dai, "You stand behind me." ”

Qing Dai's heart warmed and nodded slightly.

A small crack appeared in the left side of the wall, and it was a small door embedded in the middle of the wall, and it was opened from the inside without a sound.

Qing Dai glanced at Xu Duheng, and the two walked in slowly.

However, at this moment, the door behind them was closed silently.

As soon as Xu Duheng entered, he was stunned in place, this is a splendid decorated road, there are still holes on it, and looking at it from a distance, it is not just a door.

The entire disc-shaped space seemed to be extremely quiet all around.

And the person who heard the breath was in the door to their left.

As soon as Heng and Qingdai recovered their breath, they turned to look behind them, and Xu Duheng was instantly stunned in place, "Old valley master? ”

The unkempt old man nodded in a panic, and Xu Duheng walked up in three or two steps, reaching out and pulling out the cloth stuffed in his mouth.

Qing Dai looked at the old man, although he looked a little dirty, but his whole body still couldn't hide.

It's just that he has an iron ring tied around his waist, and the iron chain at one end hangs dead on the roof.

"Your Highness, why are you here?

I like to raid our villain boss and guide our villain boss.
