"Hehe, he probably wants to jump off the cliff to escape, right?" Yan Bing turned his head and chuckled.

When the other soldiers heard this, they couldn't help but laugh.

After the laughter, the group escorted Jiang Rong and Fan Xiaoqi to continue to walk steadily upward. With this lesson, in the future process, Fan Xiaoqi has been looking straight ahead with obscene eyes, and he no longer dares to look down.

Five minutes later, the group finally arrived at the castle gates. It was a thick and hard wooden door that was seven or eight meters high. Dozens of smooth and shiny steel balls are evenly inlaid on the wooden door every half a meter distance, and next to it are two bright-eyed gatekeepers, making this tall wooden door look more majestic and unshakable.

Since they had already known of their arrival in advance, the city gate had already opened a small crack in advance for them. After a few people had climbed the stairs, they quickly walked through the crack in the door into the castle. After shaking hands cordially with several soldiers guarding the door, Yan Bing and his gang, led by the guards, escorted the two new felons to the depths of the castle with majestic steps.

In the process of walking, Fan Xiaoqi and Jiang Rong have been observing the scenery around them with curious eyes for a few hours.

The first thing they entered was the outer structure of the castle. The outer layer of this air prison castle is about twenty meters wide, and the height is about twenty-seven or eight meters on average, as Ming just said.

But these 278 meters are the height of the outermost wall, not the average height of the entire outer structure. These walls are on average five to six meters thick and are made of unusually strong boulders. The top of the wall was built into a ring of defense around the castle. Inside, there is a flat stone road, and every five to ten meters in the solid stone wall on the outside of the road are small holes that can be used to shoot arrows from outside. Its defensive ability is comparable to the 'Great Wall' we see today, and it can be said that it is even better.

Immediately close to the inner wall of the city wall, it is built according to the situation, about 15 meters wide and about 178 meters high, with tall and magnificent buildings with stone and wooden sticks and structures. The purpose of these four- and five-story buildings is not very clear to Fan Xiaoqi. But from what he had observed, more than a dozen of them were barracks, as well as the lowest stables, storage rooms, etc., and there was no main functional building or cell in this 'Blackwater Island Air Prison'.

As they progressed deeper, they had now passed through the outer structure and reached the interior of the castle. Fan Xiaoqi's eyes are several large-scale buildings with a height of 10 to 25 meters and two to six floors made of stones. The exterior of these houses is not too ornately decorated, but it has a sense of majesty and solemnity, which is very harmonious with the atmosphere of the heavily garrisoned prison.

The function of these buildings, based on the appearance of these houses and the clothes hanging on the balconies of the houses, should be mostly recreational facilities and dormitory buildings used by sergeants.

After entering the interior, the group continued along the flat stone avenue. Soon, in front of Fan Xiaoqi's eyes, a towering building of grand and unusual scale, with a width of more than 300 meters and a height of about 20 meters, appeared. When the whole building was two hundred meters away from it, Fan Xiaoqi's entire eyes were filled, which made Jiang Rong and Fan Xiaoqi widen their eyes, and looked at the scene in front of them with a look of consternation.

"Hey, I said, what do you two want? A stout soldier saw that they had stopped, slowed down their pace, and frowned at them.

Only then did the two of them come to their senses and continue to slowly follow the steps of Yan Bing and the doorman, walking towards this unusually magnificent building.

Is this the main part of the 'Blackwater Island Air Prison', the prison and cell where the most vicious prisoners are held?

With doubts, Fan Xiaoqi was pushed forward by the soldiers as he looked up and looked more closely at the exterior of the building.

The building is a U-shaped structure with protruding about 50 or 60 meters on both sides. Together with the recess in the middle, they are surrounded by a shady sports field the size of a football field.

Like the other houses I have just seen, there is no elaborate decoration on the surface of this building, it is solemn and unshakable, grand and magnificent. The further I went, the more I was shocked and impressed by its momentum. It was as if a majestic, powerful general was looking at the people who approached him with majesty, and one couldn't help but be afraid, even a little trembling.

However, although they were shocked by the big guy in front of them, Jiang Rong and Fan Xiaoqi were still escorted by several strong soldiers behind them, and they kept moving towards the building with staggering steps.

In this way, the team led by Yan Bing arrived at the gate of this huge building not long after. The gate is made up of two beautifully crafted wooden doors that are five meters wide and seven or eight meters high, and are painted with a beautiful burgundy anti-stain lacquer. It's no less impressive than the castle gates. The wooden door is flanked by two stout and tall marble pillars that reach to the top of the building, carved with the motifs of beasts such as eagles, lions, and elephants. At the upper end of the wooden door are several beautiful and majestic characters welded with copper and iron, 'Blackwater Air Prison'. On both sides of the upper end of the big character sit two mighty and majestic eagles, also made of copper and iron, with half-open wings and grinning teeth. This majestic and heroic gate signboard not only pushes the majestic momentum of the gate to the top. It also strongly highlights the majesty and unshakability of the whole building.

Looking at this majestic gate, as well as a few big characters and eagles on the gate that are glowing with light blue reflections under the moonlight, as well as this extremely powerful building, Fan Xiaoqi's heart fluctuated, and he couldn't help but be deeply shocked, and couldn't help but feel a sense of reverence.

At this time, one of the two tall and majestic gates had been opened for them by the guards inside. The group entered the building without any hindrance.

Fan Xiaoqi took advantage of his strong curiosity surging like boiling water, and as soon as he entered the door, he quickly and alertly took a look at the environment in the building.
