The three kings held a torch in one hand, jumped to the roof, and began to search carefully, but it was very difficult to move with the torch in hand.
Long Lin stood below and also saw this situation.
It's dark now, there's no light, it's definitely very inconvenient to hold a torch on a dark roof to search for mechanisms hidden in the dark.
The best way is to wait until dawn.
During the day, although the lighting in the house is not very good, at least you can see clearly, which is more convenient than at night.
But with the clues, Long Lin didn't want to wait. He couldn't help but want to work hard to find the mechanism that opened the tunnel.
After a little thought, Long Lin came up with an idea.
"Xiaobao, come here."
Xiaobao heard the sound and immediately ran towards Long Lin.
"Your Highness, you called me?"
"Xiaobao, gather all the Imperial Guards with torches into a room, raise the torches, and light up the roof directly."
"Yes, Your Highness."
After Xiaobao finished speaking, he hurried to do it. Soon, the room they were staying in was illuminated by countless torches, and it was completely illuminated.
The Forbidden Army without torches was so numerous that there was nothing they could do for a while but all they could do was retreat.
The torch was held below, and the three kings above finally had a free hand. The three of them wandered around the roof and began to look for a place to open the mechanism.
One room was connected to the other, and it was not until the sixth room that the Ghost King was on the roof, and finally found the place to activate the mechanism.
It turns out that in this room, a little above the connection between the sixth vertical beam and the wall, there is a piece of brick that can be taken out directly.
Just inside, there is a raised disk that can rotate.
As the Ghost King exerts his strength, click click click...
There were deep sounds above, and suddenly there were muffled sounds on the ground of the house.
Although the muffled sound is obvious, it is not very loud.
With the sound, everyone immediately burst into happiness.
Some of the Imperial Guards who stood above the sound quickly moved their steps and got out of the way.
The figures of the three kings above flashed and landed smoothly on the ground, smiling at Long Lin.
The noise continued, and Long Lin came closer and listened carefully.
Down there, the sound was very dull, and it felt like the stone slabs were being pushed and moved by the mechanism, but there was no entrance on the ground.
Long Lin was not anxious, but felt a little surprised.
In this age without machinery, it is simply incredible that the mechanism can be made so superbly.
What kind of skilled craftsman is he with such superb skills?
As time went on, the sound coming from the underground felt closer and closer.
Click click click......
With a soft sound, a large stone slab on the ground slowly sank directly downwards.
"It's out, look."
Many people in the imperial army couldn't help but exclaimed in surprise.
Everyone's eyes were fixed on the large sunken stone slab.
Long Lin was standing nearby and could see it very clearly.
The area of this stone slab is quite large, probably several square meters.
After the stone slab sank, it was pushed by a force and moved directly to the side.
Only now did a passage leading downwards appear.
Yudie, who was staying outside, also discovered something unusual inside the house.
With a smile on her face, Yudie took steps and came to the house.
Everyone was no stranger to Yudie. A group of forbidden soldiers immediately moved out of the way and Yudie came to Long Lin's side.
"Thank you for your hard work. Have you found it?"
After Yudie finished speaking, she also looked towards the passage that appeared below.
Long Lin looked delighted and stretched out a hand to grab Yudie's hand.
"I've found it, I've found it... It's really not easy. It's not me who's doing the hard work, it's the Forbidden Army and everyone here."
Long Lin sighed with emotion. After everyone searched for several days, they finally found this tunnel.
This is only right. It is normal to have a tunnel. Otherwise, if the money suddenly disappears in the house, it will be unacceptable.
When Long Lin suddenly grabbed her hand, Yudie was stunned for a moment, but looking at Long Lin's delighted expression, she did not break away.
After a moment, Long Lin loosened his grip and became energetic.
"Armies, listen up. When you go down into this tunnel with torches, you must be very careful. There may be a mechanism to hurt people."
After saying this, Xiaobao immediately waved his hand.
A group of forbidden soldiers took the lead and filed directly below. In order to prevent any unexpected events, the Bird King also walked in front with the forbidden troops.
Long Lin and Yudie followed a little behind and stepped into the tunnel.
Stepping into the tunnel, surrounded by imperial guards holding torches to illuminate, Long Lin began to look around at the situation.
The tunnel is very smooth, and it was obvious that a lot of effort was put into repairing it.
It's not narrow inside, it's very spacious. Even if you push a wooden cart and walk inside, there will be no problem at all.
As we went deeper, there were no surprises. Soon, a row of underground houses appeared inside.
Long Lin stepped into one of them and showed a smile.
Inside this underground house, there are actually tables, chairs and a stone kang for resting. Although it is empty now, I think that there should have been mattresses laid on these stone kangs before.
The ground is huge and there are many houses underground.
There are probably dozens of houses in the entire row, but the houses here are not as spacious and huge as the houses above.
Now Long Lin understood that the house above was used to store money, while the house below was where everyone rested.
But Long Lin didn't understand why there was no echo from below when he hit the ground above.
Not only that, even the entrance has no echo at all when it is tapped. How is this achieved?
There was no time to think about it, and he continued to move forward behind the imperial army.
Generally speaking, wherever there is an agency, there must be a message room to control the agency, but I walked down a row of buildings and couldn't find it.
Keep going forward along the road, and the passage turns out to be very far-reaching.
The ground of this passage is all made of neat stones, and there are traces of wheels passing through it, but there is no damage to the passage at all.
At the end of the passage is a flat stone wall.
Next to the stone wall, there is an iron plate that can rotate.
Long Lin came closer and glanced at the iron plate.
"Open it."
After saying this, the Bird King stepped forward and easily rotated the disc.
Click click click......
The disc rotated, and the entire stone wall made a loud noise.
Looking at the scene in front of him, Long Lin was immediately shocked.
The rocks on the bottom layer suddenly fell downwards with a sound, and then were clearly pulled in by a force.
After the stone sank a little, a gap naturally appeared. When it moved, there was an obvious slight rolling sound between the stone and the stone above.
It's like there's a pulley inside, making a constant moving sound.
After the stone moved in, another stone of the same thickness fell downward again.
