"Woo——!"

The screeching noise of the electric drill rig continued to ring, and the dust from the drilling filled the entire basement.

Fortunately, everyone in the basement was wearing gas masks and fully enclosed protective suits, and the flying dust did not harm them in any way, at most they made them disgraced.

Suddenly, the electric drilling rig in Ye Tian's hand gently moved forward, and the harsh noise echoing in the basement disappeared, leaving only the sound of the motor idling.

Seeing this scene, everyone at the scene understood what was going on!

That piece of hard granite has been pierced by an electric drilling rig, and the secret room or secret passage hidden behind the wall is about to be unveiled today, more than 700 years later!

Next, what everyone will gain, whether it is a huge surprise or an empty joy, we will see immediately!

Almost at the same time as the sound of the motor idling, Ye Tian had quickly controlled the electric drilling rig in his hand, and began to recycle the drilling rig at a low speed in time.

In the blink of an eye, he put the rig back up, then turned it off and placed it on the floor next to it.

At this time, on the wall on the north side of the basement, there is a round hole with a diameter of about two centimeters, which leads directly to the hidden space behind the wall.

Looking at the round hole, everyone in the basement was overjoyed, and everyone's eyes were full of anticipation.

Especially the Bishop of Kent and the other high-ranking Vatican priests, they couldn't wait to step forward immediately to replace Ye Tian, and then smashed the wall with their own hands to see what was hidden behind the wall.

However, Ye Tian didn't give them this chance!

After putting down the electric drilling rig, he immediately took out a set of four-way industrial endoscopes from the trolley box next to him, quickly installed the endoscope, and simply debugged it.

Everything was in perfect condition without any problems.

Immediately afterwards, Ye Tian carefully inserted the endoscopic probe that integrated a strong light flashlight and a high-definition pinhole camera into the round hole in the wall.

As the probe gradually went deeper, the situation in the round hole and the hidden space behind the wall were presented one by one on the monitoring screen of this industrial endoscope, and the picture was very clear.

Behind this wall is a dark space, or rather the entrance to a secret room or tunnel.

Compared to the floor of the basement where everyone is located, the location of this secret space is higher, about 1.5 meters high, so that the water in the water dungeon can be prevented from penetrating into it, which is a very clever design!

The position where the endoscope probe enters, where the borehole is located, is below the secret space, near the bottom, just above the stagnant water.

Of course, this was the result of Ye Tian's deliberate choice, and it was also one of the reasons why he personally punched holes, and no one knew the situation behind this wall better than him.

After the endoscope probe entered this hidden space, it first paused, and then under Ye Tian's control, it began to slowly rotate and explore this hidden space that had been closed for more than seven hundred years.

This space shrouded in darkness is about three or four square meters, the ceiling and walls are covered with moss, and there is some standing water on the ground, which should have been washed in by the fire high-pressure water cannon just now.

To the right of the endoscope probe, there are two rusty iron chains, about the size of an adult's wrist, attached to the granite strips of the wall at one end, and the other end sloping downward, connecting to the floor through the stagnant water.

Obviously, this is the mechanism that controls the opening and closing of the door of the secret room, and after more than 700 years, it has long been rusted and may have been scrapped.

The mechanism that opened the door of the secret room from the outside must be in the basement where Ye Tian and the others were.

Judging by the situation in the basement, it is very likely that the opening mechanism is one of many burning pillars, or it may be some iron hook on the ceiling!

As the endoscope probe continued to go deeper, an arched corridor about two meters high and about one meter wide suddenly appeared on the monitoring screen.

The arched walkway, also made of granite and concrete, covered with moss, looks rather slippery and has a slight upward slope that runs due north until it is completely engulfed in darkness.

Because the length of the endoscope probe is limited and the detection range is also limited, the situation in the arched corridor cannot be seen much for the time being, and it is not very clear.

However, this is enough!

In fact, the road that has been shrouded in darkness for more than 700 years, what is the specific situation, Ye Tian is like a mirror in his heart!

Therefore, he did not plan to use the beetle drone here to fly in and explore the corridor in the dark.

Sometimes, it's wisest to hide it!

In just a few minutes, the situation in the hidden space behind the wall was basically clear.

Without exception, everyone in the basement was excited, their eyes glued to the endoscope monitoring screen, shining like a searchlight!

"Wow! There is indeed a secret passage behind this wall, and I don't know where this secret leads to, and what secrets are hidden inside?

"I hope this secret passage will lead us to the treasures of the Knights Templar, those sacred religious relics, and the huge wealth accumulated by the Knights Templar!"

While the heated discussion continued, everyone at the scene couldn't wait to step forward, directly break through the wall in front of them, enter the secret passage behind the wall, and explore the treasure!

At this moment, Ye Tian suddenly said aloud:

"Jason, you came to operate the endoscope probe, mainly to keep an eye on the situation of these two chains, I went to find the mechanism to open the door of this secret room, and open this hidden space that has been sealed for more than 700 years.

According to my speculation, the mechanism that opened the door of this secret room is most likely a certain burning pillar in the basement, which should not be difficult to find, I ignored those burning pillars before, and this time it will not be!"

"Okay, Steven"

Jason nodded in response, and then immediately stepped forward, took over the control of the four-way endoscope from Ye Tian's hand, and stared closely at the two rusty chains on the monitoring screen.

Ye Tian turned around and pretended to start looking for the mechanism to open the door of the secret room, carefully observing and trying to shake those rusty burn pillars one by one!

At this time, his every move was under the keen attention of everyone at the scene, and he had to put on a good performance, so as not to reveal any flaws.

Bishop Kent and David were originally going to come up to help and find the location of the mechanism together, but Ye Tian refused on the grounds of safety, so they just stayed where they were and watched.

Of course, you can't get them involved, in case they see that they're playing tricks and just performing, it's not fun!

After trying seven or eight burns in succession, Ye Tian came to a burn pillar in the northeast corner of the basement and began to carefully observe the burn stake and try to shake it gently.

After a moment, he suddenly said in surprise:

"Something is wrong with this burning pillar, the bottom doesn't seem to be very strong, it seems to be shaking, Jason, you keep an eye on those two chains, and tell me immediately if there is any movement, this may be the mechanism that opens the door of the secret room!"

As he spoke, Ye Tian had already exerted his strength and pushed the rusty burning pillar forward, without giving others a chance to come up and check it out!

At first, the stake remained motionless, as if it had grown on the floor.

But as Ye Tian continued to exert his strength, the rust on the stake began to fall off one after another, and then slowly leaned forward.

"Squeak——!

Suddenly, there was a sound of metal rubbing violently in the basement, which was extremely harsh, and it made people's scalps tingle and uncomfortable to listen to!

However, everyone in this basement completely ignored the noise that could almost pierce people's eardrums at this time, and they were all very excited and cheered directly.

"Great! That burning pillar is the mechanism that opens the door of the secret room, which means that this secret space that has been closed for more than 700 years is about to be revealed in front of our eyes!"

"Wow, what's at the end of that dark tunnel, what secrets are hidden?

Before everyone's cheers had fallen, Jason was already shouting excitedly.

"Steven, those two chains have finally moved, and this wall is being pulled open, and this secret room is about to open!"

Hearing this, Ye Tian immediately pretended to be surprised and said:

"This is really a bit unexpected to me, I didn't expect that more than 700 years later, this mechanism to open the secret room has not been completely scrapped, and it can still be operated, I have to say that it is a miracle!

Obviously, the Knights Templar have put a lot of thought into this chamber and built it at any cost, and I'm looking forward to what we'll find out next!"

As he spoke, the door of the secret room, which was made of a whole granite strip of stone, had slowly opened inward, and it was the straight gap that rushed out along the high-pressure water gun!
