Two high-powered ventilation fans are still working, spinning at high speed, continuing to replace the foul air in the basement.

Compared to the beginning, the stench in the castle is not so strong and suffocating.

But the Cypriot police and UN peacekeepers who stayed outside the castle, downwind and without any protective equipment, and those farther afield, were in bad luck!

The foul smell that blew in the wind, impartially, hit them head-on and surrounded them, instantly making each of them feel suffocated and almost fainted with nausea.

Immediately after, these guys rushed to their respective vehicles, got into the car in embarrassment, closed the doors and windows completely, and quickly turned on the car air conditioner, taking a big breath of fresh air, like a drowning person!

On the side of the castle, the exploration is proceeding in an orderly manner.

A few minutes later, Jason and another company employee walked out of the Gothic building with an air detector and began to report the test results to Ye Tian.

"Steven, the air in that basement has been much better, although it still stinks, but it can finally get in, the methane content in the air has been greatly reduced, and there is no danger of deflagration!"

As he spoke, Jason handed the air detector in his hand to Ye Tian.

Ye Tian looked at the data on the air detector, and then said to the people around him:

"That's true, there is no danger in the basement for the time being, let's go in and have a look, after entering the basement, everyone should be more careful, listen to my command, and don't act without permission!"

"Understood, Steven"

Jason and the others nodded in unison, and quickly checked their gear, ready to explore the basement.

Then, Ye Tian led everyone back into the Gothic two-story building, and soon came to the entrance of the basement!

Standing at the entrance of the basement to look at the situation, Ye Tian instructed his staff to remove the two high-power fans placed at the entrance, and arrange the next step.

"The situation below is unknown, for the sake of safety, there should not be too many people going in, I will only take two guys down, Jason, you and the rest of the guys will stay here to provide us with support and backup.

We'll bring an exhaust fan in and replace the air in the basement further down in the ground, and when we go down, you'll reinstall another exhaust fan at the entrance to this basement!

When the stench in the basement is almost as clear as it gets, and you're sure it's safe, you'll go down the stairs and explore to see what those hateful bats are protecting!"

"Okay, Steven, stay safe"

David and Jason responded in unison, and quickly assigned their staff.

Next, Ye Tian took two company employees, turned on the headlamps above their heads, took a high-power exhaust fan and two strong lights, and walked down the slippery steps covered with moss.

When the three of them walked down the stairs one after another, Jason and the others immediately took another high-power exhaust fan and reinstalled it at the entrance of the basement to continue to replace the dirty air in the basement.

After walking down about a dozen steps, Ye Tian and the three of them entered the basement below.

Because Jason and the others had entered this basement before, they knew that there was no other danger here except for the stench, so Ye Tian and the three of them walked down the steps with confidence.

After landing and standing still, the two company employees who followed immediately turned on the two strong lights they carried with them and placed them on the damp floor.

In the blink of an eye, the darkness that had shrouded this basement for hundreds of years was completely dispelled, and this small space was directly illuminated as if it were daylight, and everything was clearly visible!

This basement is located directly below the Gothic two-story building above, and it is located quite deep, four or five meters underground.

The walls and roof of the basement and the floor are all made of hard granite, and there are many rusty iron parts on the walls and roof, including hooks, rings, and arm-thick iron pillars!

On the north and south walls of the basement, there is a small air window, which can only let in a very limited amount of sunlight, and the air window is located very high, almost close to the roof, about three meters from the floor.

Because of its long history and lack of access, this basement is dusty and moss-grown, and the floor is so slippery that your feet are disgusting to listen to!

Fortunately, there are no dense and scalpen-tingling cobwebs that are common in other abandoned ancient buildings, and it feels a little better.

Of course, there's a little bit of credit to Jason here.

After some simple cleaning before, this basement is finally able to stand up, so that there is not even a place to stay.

In the blink of an eye, the situation in this basement was fully seen by Ye Tian.

In fact, a few hours earlier, he had seen it clearly through perspective, and all the actions that followed were nothing more than acting, just to make everything seem more reasonable and flawless!

"If I'm not mistaken, in the thirteenth century, this was the Knights Templar's cell, a place for felons, and the basement further down was probably a water prison.

The hooks and rings on the walls and roofs were originally used to hang prisoners, and the rusty metal pillars that looked like burn stakes were supposed to be used to bind prisoners.

But strangely, this cell doesn't seem to be used very often, and the wear and tear of the metal parts is not very obvious, and it is not deformed due to the frantic struggle of the prisoners!

Maybe this cell has never really been used, maybe there are other secrets hidden here, and hopefully we can find something here, then this trip to Cyprus will not be in vain."

As he spoke, Ye Tian had already stepped out, carrying the high-power exhaust fan, and walked straight to the northwest corner of the basement.

The entrance to the basement deeper, just around that corner, there was a rusty iron bar, or rather a cell door.

Behind the cell door is a dark passage and staircase that slopes downwards and leads deeper underground.

When he came to the prison door, Ye Tian did not open it immediately, but looked at the situation in the corridor behind the cell door, and then placed the high-power exhaust fan in his hand at the old door.

Immediately afterwards, he waved his hand and asked the two employees to step back a little, and then he personally activated the exhaust fan, and quickly dodged a few meters to the side, just in case!

Luckily, there were no accidents, no methane gas detonation, and no large number of bats flying out of the basement below at high speed!

As the exhaust fan began to rotate at high speed, a foul-smelling air immediately gushed out from the basement below, instantly filling the basement where Ye Tian and the others were.

Fortunately, they were prepared, everyone wore gas masks, fully enclosed protective suits, and were fully armed, otherwise they would have been smoked to death on the spot.

Under the joint action of the upper and lower high-power exhaust fans, the foul-smelling air in the basement of the lower floor is continuously pumped out, and then discharged to the outside world, and the fresh air is continuously injected!

Ye Tian and the others in the ancient castle, as well as the Bishop of Kent and his party, as well as many security personnel, because they had been prepared, each had a gas mask and a set of fully enclosed protective clothing, and they all protected themselves.

And those unprepared Cypriot police and UN peacekeepers, as well as all the other bulls, ghosts, snakes and gods guarding the vicinity of the castle, have fallen into blood mold!

As they got used to the sea breeze, the foul-smelling air kept coming, completely polluting every inch of space they were in.

Even if they hid in their cars and turned on the air conditioner to the maximum, they still couldn't resist the suffocating, pervasive stench of the air!

In just a few moments, these guys were so smoked that they were about to faint, and they wondered if they had fallen into the dung pit!

While the exhaust fan was working, Ye Tian and the three of them were not idle.

They searched the basement where they were located, and they didn't miss a single corner.

Unfortunately, they found nothing but a few mysterious symbols unique to the Knights Templar on the walls, neither secret passages nor dark rooms.

After searching this basement, Ye Tian and the others returned to the entrance of the lower basement.

At this time, the exhaust fan has been working for about ten minutes, and the air in the basement below has changed several times, and the foul smell in the air has been reduced a lot.

Ye Tian stood at the entrance of the basement and looked at the dark passage leading to the depths of the underground, and then said through the walkie-talkie:

"Jason, you move the exhaust fan from above for the time being, and stay away from the basement entrance, take care of it, we're ready to put the lights in the lower basement.

As soon as the lights are placed in the basement below, the bats in the basement will immediately fry, and then rush out and fly to other places.

What are the specific species of bats below, are they poisonous, and will they actively attack humans? It is not known at this time, everyone must be cautious, just in case!"

"Okay, Steven, don't worry, we know what to do"

Jason's voice came over the intercom and quickly went into action.

After giving the order, Ye Tian moved the exhaust fan placed at the entrance of the basement on the lower floor to the side, and then motioned to the two subordinates next to him to step back a little to avoid the impact of the bat swarm.

Immediately afterward, he stretched out his right hand, gripped the crumbling iron fence at the entrance to the basement, and pulled it outward, directly pulling open the rusty prison door.

"Boom!"

The cell door slammed into the floor with a loud bang and a cloud of dirty dust in its wake.

At the same time, a creaking scream suddenly came from the basement below, which was creepy to listen to.
