As the ventilation fan hung into the secret tunnel began to work, a large amount of dirty air accumulated in the depths of the secret tunnel was drawn out, and fresh air from the outside was continuously injected into the secret tunnel, rapidly improving the environment inside.
If there are some antique paper artworks or murals hidden deep in the secret road, such rapid replacement of air will inevitably cause irreversible damage to those objects, or even directly destroy those objects.
However, Ye Tian is not an archaeologist, so naturally he has no worries about this, and this is a secret road built in the Middle Ages, and it is basically impossible to have any paper objects inside.
In the environment of this secret passage, paper objects from the Middle Ages are also difficult to retain until now, unless they are sealed and placed in a vacuum environment.
Of course, special paper products such as parchment are excluded.
More importantly, this is France. Even if paper antique art or murals are hidden deep in the secret road, Ye Tian doesn't care whether they can be preserved intact and reproduced in the world.
Martinez and the French Minister of Culture, who were standing outside the wine cellar, cared very much, but they couldn't think of a better way for a while, so they could only watch Ye Tian and the others act boldly.
Soon, fifteen minutes passed.
Ye Tian hung the air detector into the dense tunnel again to detect the air in the dense tunnel.
After a minute or two, he lifted the air detector up, looked at the test data on it, and said with a smile:
"The air environment in the secret passage is much better. Although it can't be compared with the outside world, nor can it be compared with the air environment in the wine cellar, at least people can enter it without worrying about anaerobic suffocation.
Jason, put the drone into the secret tunnel, let the drone take us to explore this secret tunnel in depth, and see where the secret tunnel leads and what is hidden! "
"Okay, Steven"
Jason nodded in response, looking eager to try.
Afterwards, he turned on the searchlight and several cameras carried by the small drone, personally manipulated it to fly, and landed directly towards the secret tunnel entrance at the bottom of the pit.
In a blink of an eye, this small drone fell from before Ye Tian's eyes and entered the secret passage that slanted to the depths of the ground to explore the secrets hidden in the dark.
At the same time, the pictures taken by the camera carried by the drone and related data detected also appeared on the monitoring screen in Jason's hands.
"Steven, this dense road is about two meters high and 1.2 meters wide. It extends downward at a 45-degree slope. The walls and vaults on both sides are all made of granite and concrete, and they look very strong. .
On the walls on both sides of the secret passage, at a distance of five to two meters, there is a circular hole about five centimeters in diameter. It should be used to insert a candlestick or torch. There are no traces of traps.
Going down the steps for about ten meters, the secret road turned to the east, the **** dropped sharply, and became smoother, and the space in the secret road became larger and larger, but there was nothing,... "
While manipulating the drone to explore, Jason introduced the situation captured by the drone, but there was no surprise.
After standing at the bottom of the pit and listening to a few words, Ye Tian simply came up from the big pit, came to Jason, and looked at the LCD display in his hand.
On that piece of liquid crystal display, a strong light projected from the small searchlight on the belly of the drone, like a sharp sword, directly splitting the darkness, revealing the deep underground tunnel.
As Jason said before, as the drone gradually deepens, the space of the underground tunnel is getting bigger and bigger, the width has exceeded two meters, and the height has exceeded three meters.
However, the drone still found nothing, and the secret passage was empty, let alone any treasure.
The drone then flew forward a few meters. Suddenly, a rusty iron fence appeared in front, blocking the drone's path.
The first time he saw the iron fence, Ye Tian immediately reminded:
"Be careful, Jason, don't hit that iron fence"
Jason's reaction was also very quick, he quickly controlled the drone and let it hover in the air.
"Let the drone slowly fly closer to the iron fence to see if you can pass through it. If not, then check if there are gaps above the iron fence and on the left and right sides."
"Okay, Steven"
Jason nodded in response, and then controlled the drone to slowly fly towards the iron fence.
As the drone approaches, the image displayed on the LCD display becomes clearer.
It was a rusty iron fence that had been sleeping for hundreds of years in the dark. It was at the end of the secret road, and behind it was a dark space. I don't know how big it is or what it hides.
In a blink of an eye, Jason grasped the situation of this iron fence.
"Steven, the gap between the adjacent railings of the iron fence is too small. Although the drone can barely pass through, if one is not careful, it will hit those rusty railings.
There is not enough space on the top of this iron fence, and on the left and right sides, for the drone to pass through. From the ground of the dense road to the vault, it is blocked by this iron fence."
Ye Tian looked at the iron fence on the LCD, and then whispered:
"In this case, don't take the risk, let the drone hover in front of the iron fence, and then use the searchlight and night vision camera to check the situation behind the iron fence."
"Okay, Steven"
Jason nodded, then began to adjust the drone's flying posture and began to explore the dark space behind the iron fence.
The next moment, a beam of strong light passed through the rusty iron fence, sending light to the dark space behind the iron fence for the first time after a few hundred years.
The first thing that appeared on the liquid crystal display were two granite stone pillars with a diameter of about fifty centimeters, standing on the left and right at the end of the dense road, supporting the underground space inside.
The beam of light extends further in, and it is an underground space of unknown area. On both sides of the beam, a dozen long dusty boxes are stacked on each side, lying quietly in the dark world.
The next moment, the powerful beam of the searchlight fell on the boxes, showing them on the liquid crystal display.
The picture is fairly clear, but Ye Tian and Jason still don't understand what is in the boxes. The thick dust and moss on the boxes completely cover up all the information!
In desperation, their sights can only continue to follow the beam and continue to explore.
A few meters behind those long boxes, Ying Ying Chuo Chuo still has a lot of things, but because of the relationship between light and distance, it is not very real, only the outline can be seen.
Due to the obstruction of the iron fence at the end of the secret road, the angle of view of the camera carried by the drone is also greatly restricted. For the time being, only so much can be seen.
"Jason, adjust the flying posture of the drone and use a night vision lens to photograph the dark space behind the iron fence to see if you can find something."
Following Ye Tian's remarks, Jason quickly adjusted the drone's flying posture and started shooting with the night vision infrared camera carried on the side of the drone.
The pictures on the LCD display changed accordingly, showing a dim picture. On these pictures, only the outlines of various objects in the dark can be seen, but no specific situation can be seen.
Deep underground, in the dark world that has not been visited for hundreds of years, there are hundreds of boxes full of boxes of various sizes.
And this is just a box placed in the drone's shooting range. Outside the shooting range, in perhaps a larger dark space, God knows how many such boxes are left.
Seeing this scene on the LCD display, Jason was immediately stunned and stunned.
Ye Tian did the same, he was also shocked by the scene before him.
Because the depth is too large, this underground space is beyond his perspective. He naturally doesn't understand the situation in that dark world, just like Jason and others.
After just a second or two, Jason exclaimed in excitement.
"Wow! There are so many boxes hidden in this underground space. There are hundreds of them. I don't know what are in these boxes? If it is the treasure of the Knights Templar, it would be perfect!"
His voice has not yet fallen, the scene is completely boiling.
"What? Hundreds of boxes are hidden at the end of this secret road. I heard that right? If those boxes were filled with gold and silver treasures and antiques, what a huge treasure!"
"It seems that the rumors that have been circulated for hundreds of years are true. The treasure of the Knights Templar is indeed hidden in the Arzhny Castle. The previous treasure hunters just failed to find it!"
Amidst a cry of exclamation, everyone rushed up and looked at the liquid crystal display in Jason's hand.
At this moment, Ye Tianqinglang's voice suddenly came out, and it reached the ears of everyone on the scene.
"The images captured by drones using night vision infrared cameras are only a part of this underground space. How many such boxes there are in other places and whether there are other things is still unknown.
In order to figure out the real situation of this underground space It seems that I have to go and explore it myself. If there are indeed hidden treasures of the famous Templars, then it would be better.
In view of this, in order to avoid suspicion and some unnecessary troubles, Bishop of Kent, you'd better go and explore with me. There are some religious sacred objects with special significance, which I am obviously not suitable for contact!
As for safety issues, you can rest assured, Bishop of Kent, I will definitely protect your personal safety. Even if there are deadly traps in this underground space, it is estimated that it has long been scrapped! "
With that said, Ye Tian turned his head and looked at the cardinal from the Vatican with a special mission.
"No problem, Steven, I will go down and explore with you! Even if there is a sea of swords and flames below, I will not be afraid"
The Bishop of Kent nodded immediately, his tone was firm, without hesitation.
For him, this is exactly what he could not ask for, how could he refuse!
In case of history, who can refuse such a huge temptation?
