Seeing Feng Ning Yan's expression suddenly turn excited and serious, Shen Ling Jue hurriedly walked to the entrance of the passage, closed her eyes and held her breath. She placed all of her facial features into her ears, and only heard a slight sound of wind.

"It's here." He couldn't help but be happy.

The fact that there was air flowing meant that this wasn't a dead end. There was a ventilation passage.

Only a living person needs fresh air.

The three of them no longer hesitated and carefully walked forward.

Suddenly, he saw a light at the corner in front of him. A shadow was projected on the wall.

"Damn it! Tonight, I've got two nests and half a catty of pickled vegetables. Those fish, shrimp, meat, and eggs, I'll give them to those wild beasts and patrolling guards to eat …" "I'm starving …"

The man grumbled as he put down the box and grabbed the meat to eat.

It turned out to be a small guard delivering food.

"Here's my clothes." Feng Ning Yan gave a faint smile, sticking close to the wall as she quickly approached a corner. When that person turned around, she waved her hand and shot an arrow from her sleeve towards that person's throat.

The person didn't even have time to shout before he fell to the ground and died.

Jing Qi quickly helped Feng Ning Yan to take off this person's clothes, then dragged him out and threw him at the corner of another passageway.

Shen Ling Jue said: "The body will be found soon. There isn't much time left, let's go."

Feng Ning Yan quickly put on that person's clothes, put on his hat, and picked up his food box. As she walked, she tied up the sword in her belt.

She looked at her badge and saw that it had the words "Cuisine B" on it, but no name was written on it.

And the identity token on Shen Lingjue's and Jingqi's waists had the words "Patrol Officer" written on it.

"Understood. This is the division." Feng Ning Yan said.

Shen Ling Jue nodded his head: "The plate is very old and should have been used for a long time. However, they did not write their names, but only wrote the groups. It seems like the staff are always changing, only looking at the group code names, so there's no need for them to write their names. "

"Strange, why does it change so often?" Jing Qi didn't quite understand. The patrolling guards here were so important, how could they be changed so often?

Feng Ningyan couldn't understand this point either.

"Because the people from earlier have been sent out. They need someone new to replace them." Shen Ling Jue's eyes turned cold as he said, "The best food are the wild beasts and the patrolling guards, what does this mean?"

"This means that the status of the 'Beast' and the patrolling guards on this island is high?" Feng Ning Yan guessed.

Shen Ling Jue shook his head: "No, it means that they are the most useful people, and wild beasts, are definitely not the real wild beasts, but probably the killers."

It made sense. The best food was used to provide energy to the killers, and the people in the kitchen, that is, the people from the group of food, were useless. Naturally, there was no need to feed them so well.

"Great, since the people here often change, let's take advantage of this situation." Feng Ning Yan said happily.

"It's best not to be careless." Shen Ling Jue helped her arrange her identity token.

The fact that there were patrolling guards in the passageway meant that they had come to the right place.

As they continued walking, the smell of blood became even stronger. This time, even Shen Ling Jue and Jing Qi could smell it.

Not only was there the sweet smell of fresh blood, but there was also the stench of rotting flesh that had accumulated for a long time.

Even if it was the place where the Crown Prince raised assassins, why did it have to be so slovenly?

He didn't walk too far and saw a winding staircase in front of him. The light below was very strong.

He looked down, stunned, from the edge of the stairs.

There were at least a dozen floors below him. As he descended the stairs, he saw that there was a metal door every so often. There were windows on the door, making it look like a prison cell.

The strongest light rays and the strongest smell of blood also came from the bottom layer.

Even though there was only one guard between the two floors, Shen Lingjue had Feng Ningyan follow behind him just in case. He and Jing Qi took the lead and walked down the stairs.

The two of them held torches up, and the eye-piercing light just happened to block their faces. The identity token on their waists swayed for a moment, and when those people saw it, they didn't doubt it at all.

Feng Ning Yan held the food box and walked behind the two while bowing. It seemed like she had to bend because the food box was too heavy, so no one paid attention to her face.

Walking and walking, seeing that there were no guards nearby, she couldn't help but take a glance inside the iron gate by the stairs. With a single glance, she gasped.

It turned out that behind every metal door was a stone room. The stone rooms were not small, and each stone room had three to five people shackled inside, as well as a lot of training equipment.

It seemed that they were all eating and sleeping here. Apart from sleeping, they were all training in martial arts, and they were all training in shackles. This was simply inhuman treatment.

"Don't look around." Shen Lingjue reminded her in a low voice.

The three of them continued down until they reached the bottom level. They saw a wide, red wooden door. There were countless shiny rivets on the door, and roars could be heard coming from the inside. It really did sound like a wild beast.

At this point, the stench of blood had already made Feng Ning Yan feel nauseous.

What exactly is behind this door, the slaughterhouse?

When the two guards at the door saw Shen Ling Jue and Jing Qi walking over, they shouted:

"Why are you all so slow! "Hurry up and change shifts, we two brothers are almost suffocated to death by a piss, those beasts haven't even decided who's going to win …"

Shen Ling Jue looked at Jing Qi, and the two of them understood each other.

So these two were waiting for someone to take over.

Judging from the "Patrol Officer" tags on their waists, it seemed like they weren't the same type of patrolling guard who died earlier. No wonder they didn't recognize each other.

It was probably because this island was very secretive and the inspection was very strict, so the people inside were not very vigilant. When they saw the identity token, they thought it was undoubtedly their own people and didn't believe that outsiders would barge in.

Shen Ling Jue and Jing Qi walked over to take the place of the two guards.

After the two guards left their posts, they saw where Feng Ningyan was standing and said, "Quickly go in! The people inside are waiting to be fed! "

Feng Ningyan did not expect the rice in her hands to be delivered to the 'slaughterhouse' in front of her. She suppressed the uncomfortable feeling in her stomach and hastily nodded her head before carrying her food box to the door.

When the red door opened, the scene inside startled her even more.

Inside the door was a large arena filled with obstacles and equipment. The floor was littered with "fresh" corpses, and blood was flowing in rivers.

On the ground, in the crevices of the rocks, there were traces of black blood. No wonder it smelled so bad.

Within the battle stadium, there was a group of ragged, blood-colored people fighting with their lives on the line.

Their eyes were bloodshot. No matter who they saw, as long as they were alive, they would kill.

Pitiful roars and screams rang out as blood and flesh splattered everywhere, causing Feng Ningyan to think of a battlefield that was filled with flames.

On the battlefield, there were at least a few factions that could fight each other. There were also their warriors who could take care of each other, and each of them had their own reasons for fighting.

However, the people in the battle coliseum only killed people for the sake of killing others. They had no camp and did not know how tired they were. They did not even dare to stop until they received an order.

The battle arena was surrounded by high, barbed iron fences, and outside the fence was a high platform. On the high platform sat three people, looking down coldly at the battle stage, their gazes were numb, as if they were looking at a bunch of ants.

Shen Lingjue and Jing Qi took the opportunity to peek in when the door was opened and were shocked when they saw the three people.
