Ten minutes later, Jason and his family returned to the basement with a high-pressure water cannon, along with a water hose that connected to a powerful water pump on the ground and a fire truck.

In this way, when you use a high-pressure water cannon to wash the secret room and corridor behind the wall, you don't have to worry about running out of water or stagnant water, and you can completely recycle it.

Next, Ye Tian and Jason did it together, and they quickly made preparations.

Before turning on the high-pressure water gun and carrying out the operation, Ye Tian reminded everyone at the scene again.

"For the sake of safety, it's best for everyone to avoid a little, don't stand in the opposite direction of the secret room and the corridor, under the strong impact of the high-pressure water cannon, if there is a trap here, it is very likely to be triggered immediately!"

So saying, he stepped out to the side and stood on the east side of the door of the secret room.

The high-pressure water cannon in his hand pointed diagonally at the west wall of the chamber, ready to fire.

"Okay, Steven, we'll be safe!"

Everyone at the scene responded in unison, and then flashed to both sides, standing in front of the walls on both sides, watching Ye Tian's actions.

After everyone dodged away, Ye Tian said through the walkie-talkie:

"Peter, now have the firefighters open the water valve, we're ready!"

"Roger, Steven"

Peter, who remained on the ground, responded, and sprang into action.

In the blink of an eye, the shriveled water pipe on the floor quickly bulged, and the sound of water flowing sounded in everyone's ears at the same time.

At the same time, Ye Tian also used both hands to hold the high-pressure water gun nozzle in his hand tightly, so as not to prevent the thing from jumping out of his hand, losing control and scurrying in the basement, turning into a deadly weapon!

When all the water pipes spread on the ground bulged up and the water flow quickly rushed to the vicinity of the nozzle of the high-pressure water gun, Ye Tian's right hand that held the high-pressure water gun tightly squeezed it violently and directly opened the water spray valve.

As he moved, a powerful stream of water shot out from the spout of the water gun, and struck the moss-smeared, slippery wall on the west side of the chamber like lightning.

"Bang"

With a loud bang, water splashed and spilled all over the basement.

In an instant, the white high-pressure water flow accurately hit the wall, directly sending a thick piece of moss on the wall flying, revealing the granite wall below!

There were no traps triggered, no dense rain of arrows flying out, and no deadly weapons such as javelins and poisonous smoke, it was obviously a solid wall, very safe!

Seeing this scene, everyone at the scene couldn't help but breathe a sigh of relief and relax a little!

Immediately afterward, the senior priest beside the Bishop of Kent exclaimed.

"Wow, there are other crosses carved on that wall, as well as the Knights Templar's insignia, and two Templars with shields and spears riding a war horse, and the shield is painted with other crosses of the horses, as a sign of the friendship of the Knights!"

Before his words fell, the kid Jason jokingly said:

"As far as I know, there is another interpretation of the Knights Templar insignia, in the eyes of King Philip IV of France, it is a symbol of homosexuality in the Templar Order, and to be honest, it does look very similar!"

"Hahaha"

There was a loud laugh at the scene, and everyone laughed.

While speaking, Ye Tian used a high-pressure water gun to rush out a clean wall, on which was engraved a line of flower-style Latin.

"God's will!" was the slogan that the Knights Templar shouted during battle, and it was they who charged into battle on the battlefield!"

This time it was the Bishop of Kent who spoke out, and he was quite emotional.

Hearing this, several fellows standing on the opposite side of the Bishop of Kent all looked at the line of flowery Latin, and everyone was extremely excited.

The guys standing on the west side of the door of the secret room scratched their ears and cheeks one by one, but they could only watch with their eyes, and could only wait for Ye Tian to turn to their side and wash the wall on the east side of the secret room with high-pressure water.

At this time, Ye Tian was still holding the high-pressure water gun in his hand, and kept washing the west wall of the secret room with a strong flow of water.

The strong flow of water hit the granite wall, like an autumn wind sweeping away the leaves, washing away all the dirt attached to that wall in an instant!

"Bang Bang Bang"

The sound of high-speed water hitting the walls was constant and uninterrupted, and the entire basement was filled with layers of mist.

Everyone here even has the illusion of standing under the waterfall, but the splash mist is indeed a bit dirty, mixed with a lot of moss debris and other garbage!

Fortunately, everyone is wearing gas masks and fully enclosed protective suits, so they don't have to worry about getting wet with sewage.

Under the continuous impact of the high-pressure water, the moss attached to the wall was washed away by the water in a blink of an eye, and the granite wall gradually returned to its original appearance and appeared in front of everyone's eyes.

The granite walls are engraved with the Knights Templar's emblem, horse crosses, insignia and slogans, as well as many mysterious symbols unique to the Knights Templar!

Like the Templar mystical symbols that we had seen before, we didn't know them and didn't understand their meanings.

Soon, Ye Tian washed the wall on the west side of the secret room, and then moved the nozzle of the high-pressure water gun, and began to wash the moss and dust on the ceiling and floor.

At the same time, the moss and dust washed down by the high-velocity current, mixed with the current, had overflowed the chamber and flowed to the basement floor.

Like the west wall, the ceiling and floor of the vault are engraved with the Knights Templar's emblem and insignia, as well as some mystical symbols, but not as many as on the walls!

And there are no traps on the ceiling or floor, they are all made of extremely hard granite and concrete, so water can't splash in!

It only took more than a minute for Ye Tian to completely wash the western half of the secret room, then closed the water valve and stopped temporarily.

Immediately afterward, he smiled and said:

"Obviously, there are no traps in this secret room at the front of the corridor, don't worry about it for the time being, as for whether there are traps in the corridor, it's hard to say now, let's still be cautious!"

"It would be great if there were no traps in the corridor, and it would undoubtedly save a lot of trouble."

Bishop Kent echoed, and the rest of the group nodded.

Next, Ye Tian walked to the west side of the door of the secret room with the high-pressure water gun, turned on the high-pressure water gun again, and began to wash the east wall and ceiling, as well as the floor of this secret room!

In just a few moments, the small secret room at the front of the corridor was completely washed away, and after more than 700 years, it finally revealed its original face!

As was the case on the west side of the Vault, the walls and ceilings on the east side of the Vault, as well as the floor, were carved with Templar symbols, insignia, slogans, and mystical symbols.

There are also no traps in this half of the chamber, only granite strips that have just been washed clean and renewed.

After washing this secret room, Ye Tian casually turned off the high-pressure water gun, then picked up the walkie-talkie and said:

"Peter, have the Larnaca firefighters turn on the pumps and pump all the water from the basement onto the fire trucks for recycling, so we can get on with our work!

Tell those firefighters to work hard and keep it confidential, and when it's over, each of them will have a big surprise!"

As soon as he finished speaking, Peter's voice came over the intercom.

"Roger, Steven, I'll tell those guys that they're going to be crazy!"

Ten seconds later, a burst of excited cheers suddenly sounded in the long-abandoned ancient castle, which carried far away with the wind.

Immediately afterward, there was another sound of engines spinning in the castle.

A powerful water pump placed next to the two fire trucks was already running at high speed, continuously pumping up the stagnant water in the basement where Ye Tian and the others were, and then recycling it!

And deep underground, the high-pressure water gun nozzle in Ye Tian's hand was already aimed at the arched tunnel, which was ready to open the water valve for flushing!

At this moment, the Bishop of Kent, who was hiding on the side, suddenly said:

"Steven, if possible, you'd better let the high-pressure water avoid the medieval bronze candelabra on the walls, and the horse cross that hangs from the top of the road!

These things can be regarded as antique relics, and it is not easy to preserve them from the Middle Ages to the present, so it is best not to destroy them, so as not to block some people's mouths, so as not to cause some unnecessary trouble!"

"No problem, Bishop of Kent, even if you don't say it, I will take care to protect these antique artifacts, and don't forget, I am an expert in antique art!"

Ye Tian smiled and nodded in response, and then opened the water spray valve of the high-pressure water gun again.
