The first half of this secret passage looks like a shaft.
Looking down from the entrance on the floor, the depth is about four meters, and the bottom is dark.
There is a tunnel that slopes downward at the bottom of the well, extending eastward.
Where exactly that corridor leads is unknown.
As Xiao Ran said before, the entrance to this secret passage has been reinforced with steel plates and is very strong.
The inside of the secret passage is made of blocks of granite, which is also very strong.
The steel ladder installed in the secret passage is made of stainless steel and is in very new condition.
In addition, there is a wall lamp installed at the bottom of this secret passage, but it is not lit.
Everyone stood at the entrance and looked inside the secret passage. Everyone was very excited.
"Wow! The specifications of this secret tunnel look very high! It doesn't look like Miles and the others can dig it out in a short time!"
"This is really an unexpected surprise. I wonder what is at the end of this secret passage and what secrets or treasures are hidden?"
While checking the situation, everyone was also talking about it.
At this moment, Xiao Ran suddenly smiled and said:
"Yes, ladies and gentlemen, this underground secret passage was indeed not built by Miles and McCann."
"According to my observation, this secret passage should be about a hundred years old, which is basically consistent with the construction period of this historical building."
"In other words, this secret passage was built in the same era as this historical building. It is part of this building, but it is just unknown!"
"Perhaps it is because of this underground secret passage and the underground space at the end of the secret passage that Miles bought this place and transformed this secret underground space into an underground treasure house."
Hearing this, everyone nodded.
No one had any objection to Xiao Ran's conclusion.
Next, Frank couldn’t wait to say:
"Sean, now that we have discovered this underground secret passage, let's go down and explore it."
"At the end of this secret passage, there may be hidden a large amount of antique artworks and gold and silver treasures stolen by Miles and McCann."
Xiao Ran looked at this greedy guy, and then shook his head.
"Don't worry, Frank, it's a bit too risky to send people out to explore now."
"We still need to conduct some exploration and use various equipment to basically understand the situation in the secret passage before sending people down!"
"I am responsible for the safety of my staff and everyone, which is very important."
Hearing what he said, Frank and the others could only nod.
After chatting for a few more words, Xiao Ran began to plan the next step of exploration.
He called Nick and other employees over and told them.
Let them use pulse metal detectors and deep ground-penetrating radar to carefully detect the tunnel along the bottom of the secret passage.
Find out the depth and direction of the corridor, find the underground space at the end of the corridor, and determine the depth and structure of the underground space.
After receiving the order, Nick and the others immediately took action with various exploration equipment.
Immediately afterwards, Xiao Ran took a few more fluorescent lighting sticks, folded them one by one, lit them up, and threw them all into the secret passage.
As these fluorescent lighting rods landed, the bottom of the secret passage was suddenly illuminated.
Looking from top to bottom, there is nothing special at the bottom of the secret passage, and there seems to be no traps.
Next, Xiao Ran called Haipeng and another small drone pilot over and began to arrange tasks for these two guys.
He asked two people to fly two small drones into the secret passage, and use the high-definition cameras and other equipment carried by the drones to explore the situation deep in the secret passage.
After a while, two small drones flew into the secret passage one after another and started further exploration.
Everyone who had gathered at the entrance of the secret passage had come to the big-screen TV to watch the images transmitted back from the depths of the secret passage by two small drones.
The situation in the first half of the secret passage is the same as everyone Xiao Ran said.
There are no deadly traps or anything else, just a wall lamp.
When the first small drone flew to the bottom of the secret passage and pointed its high-definition camera at the east-facing corridor, the situation in the corridor immediately appeared before everyone's eyes.
This is a corridor that slopes downward, about 1.8 meters high and about 1 meter wide, which is quite spacious.
The vaults, walls and floors in the corridor are either made of granite or red bricks, which look quite solid.
Wall lamps are also installed on the walls on both sides of the corridor.
Judging from the style of those wall lamps, they are all modern items and relatively new. They should have been installed by that guy Miles.
In addition, there is a distribution box on the wall at the entrance to the corridor.
No special marks, holes or other things were found on the floors, walls and vaults of the corridor.
Judging from this alone, there seems to be no traps in this corridor.
Under the illumination of the searchlight carried by the small drone, we can also see a little bit of the situation deep in the corridor, but it is not clear.
Because there is a bend deep in the corridor, the searchlight cannot illuminate very far.
At the end of the light is an arc-shaped bend. As for the situation deeper in the corridor, it is unknown!
Another point is that the floor and walls of this corridor are quite clean, there is not much dust, and there is no moss.
The air escaping from the secret passage is also relatively humid, even better than the air in the piano store.
Seeing the situation in this corridor, everyone suddenly became more excited, and everyone was looking forward to it.
At this moment, Xiao Ran began to introduce the situation.
"It can be seen that Miles and McCann often go in and out of this underground secret passage, so they keep it so neat and tidy."
"Judging from the secret passage we have seen so far, there should be no fatal traps in it, and it is relatively safe."
"This may be related to the large amount of stolen antiques, artworks, gold and silver treasures stored inside. Miles and the others may not dare to significantly modify this already existing secret passage."
"Also, based on the analysis of the moist air escaping from the secret tunnel, it is very likely that a constant temperature and humidity system is installed in the space hidden deep underground."
"The existence of the constant temperature and humidity system shows from the side that there should be a large number of stolen antique artworks stored in this underground space!"
"Of course, these are just my speculations. Whether they are accurate or not requires further verification to prove!"
Listening to his analysis, everyone at the scene was shocked and excited!
What a little effort, what two small drones captured, but this guy Sean actually made so many new discoveries!
How on earth did he do it? Simply amazing!
Just as everyone was sighing secretly, Timothy suddenly said excitedly:
"I don't know anything else. There must be a constant temperature and humidity system installed in this underground space. I'm very sure of this!"
"The air escaping from this secret passageway, both in temperature and humidity, is the same as the constant temperature and humidity exhibition hall environment in our museum."
"What needs to be preserved in a constant temperature and humidity environment? Everyone knows that it is valuable paintings and other antiques."
"It can be determined from this that there must be many valuable paintings hidden in this secret underground space."
Before he finished speaking, Peggy and several other museum executives and appraisal experts nodded in agreement.
At the same time, everyone's eyes were shining with excitement.
Xiao Ran smiled and nodded, and then issued the next instruction.
"Guys, you can let two small drones enter the corridor to explore the situation deep in the corridor."
"Be careful and turn on the infrared detection device during flight."
"There seems to be no traps in this secret passage. It is probably difficult to modify and install, but be careful with some modern alarm devices."
"One more thing, you should pay attention to the various holes, special symbols, etc. that may exist on the ground, walls, and vaults, and take pictures of them all for me..."
After some orders, two small drones flew into the next section of the secret passage one after another and continued their exploration.
The picture displayed on the big-screen TV also changed accordingly.
In a moment, the first small drone that flew into the corridor arrived at the distribution box installed inside the entrance of the corridor.
This distribution box has no lock and can be opened easily.
Through the glass window on the distribution box, you can see several small indicator lights on inside.
From this, it can be determined that electrical equipment is continuously operating in this underground space.
These equipment should include constant temperature and humidity temperature control equipment, humidification equipment, etc.
Next, the two small drones continued to fly forward.
At this moment, Nick and two other employees suddenly returned to the entertainment hall and came to report the situation.
Coming closer, Nick immediately said excitedly:
"Sean, we used pulse metal detectors and deep ground penetrating radar to find out."
"This underground secret passage is about 20 meters long in total. If you count it from the basement, the shallowest part of the secret passage is four and a half meters away from here, and the deepest part is just over eight meters away from here."
"The secret passage continues eastward, with two relatively large turns in the middle, forming an overall S shape!"
"At the depth that the metal detector can detect, we only found very few metal signals in the secret passage, which should be things like wall lamps and wires."
"In other words, at the depth that can be scanned, there should be no fatal traps in the secret passage. The situation deeper than that is unknown!"
"At the end of this S-shaped secret passage, there is an underground chamber with an area of about 100 square meters. It is located more than eight meters underground from here, and the deepest point is about 14 meters."
"The location of this underground secret room is just below the back garden of the piano store. The architectural layout looks like an underground shelter..."
Before Nick could finish his report, the scene was already going crazy.
"Oh my God! Did I hear you correctly? There is an underground shelter of about 100 square meters more than eight meters below our feet. It's incredible!"
"Wow! How many stolen antiques and artworks are hidden in such a huge underground space? I don't even dare to think about it!"
Just when everyone was exclaiming, a new situation suddenly appeared.
