As the ventilation fan that was hoisted into the secret passage began to work, a large amount of dirty air accumulated in the depths of the secret passage was pumped out, and fresh air from the outside world was continuously injected into the secret passage, rapidly improving the environment inside.

If there are some paper antique artworks, or murals hidden in the depths of the secret passage, such a quick displacement of air will inevitably cause irreversible damage to those items, or even directly destroy those items.

However, Ye Tian is not an archaeologist, so he naturally has no concerns about this, and this is a secret passage built in the Middle Ages, and it is basically impossible for any paper items to exist in it.

In the environment of this secret passage, it is difficult to preserve the paper objects of the medieval period until now, unless they are sealed and placed in a vacuum.

Except, of course, for special paper products such as parchment.

What's more, this is France, even if there are paper antique artworks or murals hidden in the depths of the secret passage, Ye Tian doesn't care very much about whether they can be preserved and reproduced in the world.

Martinez, who was standing outside the wine cellar, and the French Minister of Culture cared very much, but they couldn't think of a better way for a while, so they could only watch Ye Tian and them take drastic action.

Soon, fifteen minutes had passed.

Ye Tian hoisted the air detector into the secret passage again to detect the air in the secret passage.

After a minute or two, he lifted the air detector, looked at the test data on it, and then said with a smile:

"The air environment in the secret passage is much better, although it can't be compared with the outside world, and it can't compare with the air environment in the wine cellar, at least people can enter it, and there is no need to worry about anaerobic suffocation.

Jason, put the drone into the secret passage, let the drone take us together, explore this secret passage deeply, and see where this secret passage leads and what is hidden!"

"Okay, Steven"

Jason nodded in response, looking eager to try.

Then, he turned on the searchlight and several cameras carried by the small drone, and personally controlled it to fly and fall straight to the entrance of the secret passage at the bottom of the pit.

In the blink of an eye, this small drone fell from Ye Tian's eyes and entered the secret passage that led diagonally to the depths of the underground to explore the secrets hidden in the darkness.

At the same time, the footage captured by the camera carried by the drone and the relevant data detected also appeared on the surveillance screen in Jason's hand.

"Steven, this secret passage is about two meters high, about one meter and two meters wide, and extends downward at a 45-degree inclination, and the walls and vaults on both sides are all made of granite and concrete, which looks very solid.

On the walls on both sides of the secret passage, at intervals of five to two meters, there is a round hole with a diameter of about five centimeters, which should be used to insert candlesticks or torches, and there is no trace of traps.

About ten meters down the steps, the passage turned to the east, the slope dropped sharply, and the space in the passage became larger and larger, but there was nothing ,......"

Jason manipulated the drone to explore and introduce the situation captured by the drone, and there were no surprises.

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's side, and looked at the LCD in his hand.

On that liquid crystal display, a strong light was projected from the small searchlight on the belly of the drone, like a sharp sword, directly splitting the darkness and presenting the situation in the depths of the underground secret passage.

As Jason previously introduced, as the drone gradually went deeper, the space of the underground secret passage became larger and larger, with a width of more than two meters and a height of more than three meters.

However, the drone still didn't find anything, and the secret passage was empty, not to mention any treasure.

The drone then flew forward a few more meters, and suddenly, a rusty iron fence appeared in front of it, blocking the drone's path.

The first time he saw the iron fence, Ye Tian immediately reminded loudly:

"Be careful, Jason, don't hit that iron fence"

Jason's reaction was also quick, and he quickly took control of the drone and left it hovering in mid-air.

"Let the drone fly slowly close to the iron fence to see if you can pass through it, and if not, see if there are any gaps above the iron fence and on the left and right sides"

"Okay, Steven"

Jason nodded in response, and then slowly flew the drone towards the iron fence.

As the drone gets closer, the picture presented on the LCD becomes clearer.

It was a rusty iron fence that had been sleeping in the dark for hundreds of years, at the end of the secret passage, and behind it was a dark space, I don't know how big it was, and I didn't know what was hidden.

In the blink of an eye, Jason mastered the situation of this iron fence.

"Steven, the gap between the adjacent railings of the iron fence is too small, and although the drone can barely pass through, if one is not careful, it will crash into those rusty railings.

There is not enough space on the top of this iron fence, as well as on the left and right sides for drones to pass through, and it is blocked from the floor of the secret passage to the vault."

Ye Tian looked at the iron fence on the liquid crystal display, and then said in a low voice:

"In that case, don't risk it, let the drone hover in front of the iron fence, and then use searchlights and night vision cameras to see what is going on behind the iron fence"

"Okay, Steven"

Jason nodded, then began to adjust the flight attitude of the drone, and began to explore the dark space behind the iron fence.

The next moment, a bright light passed through the rusty iron fence, sending light to the dark space behind the iron fence for the first time in hundreds of years.

The first thing that appeared on the LCD was two granite pillars with a diameter of about 50 centimeters, standing on the left and right sides of the end of the secret passage, supporting the underground space inside.

Further inward, the beam is an underground space of unknown size, on both sides of the beam, stacked with a dozen dusty crates, lying quietly in the dark world.

The next moment, the powerful beams of the searchlight fell on those boxes, presenting them on the liquid crystal display.

The picture is quite clear, but Ye Tian and Jason still can't figure out what is in those boxes, and the thick dust and moss on those boxes completely cover up all the information!

In desperation, their eyes could only continue to follow the beam and continue to explore.

A few meters behind those long crates, there were many other things, but because of the light and distance, they could no longer be seen very realistically, and only a rough outline could be seen.

Due to the obstruction of the iron fence at the end of the secret passage, the angle of view of the camera carried by the drone is also very limited, and it can only see so much for the time being.

"Jason, adjust the flight attitude of the drone, and use the night vision lens to shoot the dark space behind the iron fence and see if you can find something"

With Ye Tian's words, Jason quickly adjusted the flight attitude of the drone and began to shoot with the night vision infrared camera carried on the side of the drone.

The picture on the LCD changes to a dark picture in which only the outlines of various objects in the darkness can be seen, but the specific situation cannot be seen.

Deep underground, in the dark world that had not been visited for hundreds of years, there were hundreds of chests of different sizes.

And this is just a box that is placed in the range of the drone, outside the shooting range, in perhaps a larger dark space, God knows how many more such boxes there are.

Seeing this scene on the liquid crystal display, Jason was immediately stunned and stunned in place.

Ye Tian was the same, he was also shocked by the scene in front of him,

Because of the depth, this underground space was beyond his perspective, and he naturally didn't understand the situation in that dark world, just like Jason and them.

After only a second or two of stunned, Jason exclaimed excitedly.

"Wow! There are so many chests hidden in this underground space, there are hundreds, I wonder what these chests contain? If it's a Templar treasure, it couldn't be better!"

Before his words fell, the scene was completely boiling.

"What? There are hundreds of chests hidden at the end of this secret passage, did I hear me right?

"It seems that those rumors that have been circulating for hundreds of years are true, and the treasure of the Knights Templar is indeed hidden in the castle of Arzhni, and the previous treasure hunters just failed to find it!"

In the midst of an exclamation, everyone has hula-la-la, and they all look at the LCD in Jason's hand.

At this moment, Ye Tianqing's voice suddenly came out and reached the ears of everyone at the scene.

"The images captured by the drone using the night vision infrared camera are only a part of this underground space, and it is unknown how many such boxes are in other places and whether there are other things.

In order to find out the true state of this subterranean space, it seems that I will have to go down and explore it myself, and if this is indeed the hidden treasure of the famous Knights Templar, it would be great.

In view of this, in order to avoid suspicion and some unnecessary trouble, Bishop of Kent, it is best for you to go down with me to explore, there are some religious relics of special significance, which I am obviously not suitable to touch!

As for safety, 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 they have long been scrapped by now!"

As he spoke, Ye Tian turned his head to look at the cardinal from the Vatican with a special mission.

"No problem, Steven, I'll go down with you to explore!

Bishop Kent immediately nodded and said, his tone was categorical and without the slightest hesitation.

For him, this is exactly what he can't ask for, how can he refuse!

In case it goes down in history, who can refuse such a huge temptation?
