After a while, everyone was ready.
Xiao Ran and Henry all wore gas masks, and several exploration team members working at the bottom of the pit wore full protective equipment for safety.
Elaine, Fang Yufei, and others retreated into the lobby on the first floor of the apartment building.
After everything was ready, Xiao Ran gave the next order.
"Guys, you can start cutting, everyone must pay attention to safety"
"If you find something is wrong, stop taking action and the guys on the ground will pull you up as soon as possible."
As soon as the words fell, several exploration team members standing at the bottom of the pit responded immediately.
"Copy that, boss, we will pay attention to safety"
After saying that, these guys started taking action.
They started the portable water jets in their hands and used the high-speed water jets rich in emery to start cutting on the secret tunnel vault.
And they cut along the seams of the bricks, so that damage to the secret passage can be minimized.
As soon as the jet of high-speed water touched the vault of the secret tunnel, it cut in without any hindrance like a hot knife cutting through butter.
Seeing this scene, Renault and others standing on the edge of the pit above were filled with envy.
Top-notch exploration equipment like this undoubtedly makes them very coveted!
It’s a pity that the Louvre doesn’t have that much money to buy these exploration equipment that may not be used even once a year!
The cutting process went very smoothly and the secret tunnel vault did not collapse.
As a hole was cut in the vault of the secret passage, bursts of filthy air immediately spewed out from the secret passage.
After the filthy air rushed out of the secret passage, it first spread at the bottom of the pit, and then rushed to the ground.
Immediately afterwards, they were pumped away by three powerful ventilation fans arranged at the entrance of the pit, and discharged to the street behind through temporary pipes.
In this case, everyone present will naturally not be affected.
It took about fifteen minutes to cut an entrance half a meter long and half a meter wide into the vault of the secret passage.
Some of the bricks cut from the vault were taken out, but most of them fell into the corridor.
There was no reaction in the corridor, which was enough to explain.
There are no fatal traps in this underground tunnel, at least not under the newly opened entrance.
After the preliminary demolition work was completed, the two exploration team members responsible for cutting immediately turned off the water jet and temporarily stopped cutting.
Immediately afterwards, Xiao Ran came to the edge of the pit again and checked the situation.
He naturally knew what was going on in the corridor.
After pretending to look carefully for a moment, he said aloud:
"Guys, throw a few fluorescent lighting rods into the corridor, and then send two small drones in to explore the situation in the corridor."
"After confirming safety, expand the entrance to the corridor, and then enter the corridor to start the next step of exploration."
As the order came out, the two exploration team members standing at the bottom of the pit immediately took action.
They first took out several fluorescent lighting rods, folded them one by one and lit them, and then threw them into the corridor from the entrance.
At the same time as several fluorescent lighting rods fell to the ground, this secret underground passage that had been shrouded in darkness for more than two hundred years finally welcomed the light again.
Looking down from a high position, all I can see is a pile of broken bricks and nothing else.
Immediately afterwards, two small drones flew down from above the pit entrance, passed through the newly cut entrance one after another, and flew into the underground tunnel.
There is a strong searchlight hanging on the belly of the two small drones.
There are several high-definition cameras and an infrared night vision camera scattered around the nose and surroundings.
When these two small drones flew into the corridor, the scene inside the corridor immediately appeared on the monitor.
Xiao Ran, who retreated under the umbrella, watched the scene on the big-screen TV with Henry and the others.
The first thing everyone saw was naturally a dark corridor.
It is about two meters high and about 1.8 meters wide. It is entirely made of granite and red bricks and looks quite solid.
Within the scope of the light, there are several rooms staggered on both sides of this underground corridor.
It is not known what is going on in these rooms, nor is it known what is hidden in them.
Judging from where the light shines, this underground passage is connected to the apartment building, but the entrance in the basement of the apartment building has long been blocked.
In addition, there are several rusty bronze candlesticks on the walls on both sides of this underground corridor.
Seven or eight meters away in front of the corridor, there seemed to be some boxes stacked on the ground on the left and right sides.
The items contained in those boxes should be some metal items.
More metal objects are hidden in the rooms on both sides of the corridor.
Another point is that although there is a lot of dust accumulated inside the corridor, there is no sign of collapse.
Through the footage transmitted by two small drones, everyone had a preliminary understanding of the situation of this underground tunnel.
Looking at the boxes piled on both sides of the corridor, everyone was very excited.
"What exactly are contained in those boxes? They are hidden so secretly. Could they be valuable antiques or gold and silver treasures?"
Henry said excitedly.
Before he finished speaking, Cornell shook his head slightly.
"If these items were collected by members of the Jacobin Committee of Public Safety, the likelihood that they are antiques is relatively small."
"In that turbulent era, the radical Jacobins did not attach much importance to antiques and art, but instead caused a lot of damage."
"Compared to antiques and artworks, I hope those boxes contain a large amount of historical documents. Those things will be more valuable."
The next moment, Carlin suddenly interrupted.
"Sean, let your exploration team control the small drone and continue exploring. Everyone wants to see the condition of those boxes."
Xiao Ran glanced at these French guys, and then shook his head slightly.
"Gentlemen, please be patient. You will see the condition of those boxes soon."
"Before that, I plan to take a look at the walls and vaults on both sides of the corridor, as well as the condition of the ground."
"Although we have not detected any traces of traps before, we still have to be careful."
Hearing this, Henry and Carlin could only nod.
Next, Xiao Ran picked up the walkie-talkie and informed the two drone pilots.
Let them control the two small drones and get close to the walls on both sides of the corridor, the vaults above, and the ground to check the situation in these places.
Following his instructions, the two pilots immediately took action.
The next moment, two small drones flew to one side of the wall one after another and began to take pictures of the situation on the wall.
Fang Yufei, who provided background technical support, quickly enlarged the footage captured by the drone and displayed it on a large-screen TV.
Although the two walls were covered with dust, they were quite smooth.
There are neither holes nor any patterns or murals on the walls. They look ordinary.
Next, two small drones took pictures of the vault and the floor.
After some analysis, Xiao Ran did not find any traps in these places.
After confirming this, he told the two pilots to control the two small drones and continue to explore forward.
The next moment, two small drones flew forward slowly, one behind the other.
After only flying forward for about three meters, we arrived at the door of the first room on the right side of the corridor.
There is no door to this room. You can go in directly, but it is completely dark inside.
"Fly into this room and explore, see what's in the room"
Xiao Ran said through the intercom.
"Okay, Sean."
The two pilots responded in unison.
The next moment, two small drones began to change direction, preparing to fly into the room to explore.
The moment the two small drones turned around, everyone saw them immediately.
In the room shrouded in darkness, there were actually a dozen boxes piled up.
