This prison, both inside and outside, is made of hard rock. It can be seen that the builders put a lot of effort into building this prison. If someone is imprisoned in this megalithic prison, even if they don’t get on the chains, they probably won’t be able to escape easily.

Kakashi sneaked into the prison and discovered that although the outside of the prison was heavily guarded, there were very few internal guards.

The megalithic prison occupies a large area, but the internal space is extremely small. There are only more than a dozen cells, and most of the other areas are filled with megaliths.

Kakashi explored these cells one by one, some cells were holding people, some cells were empty.

There are seven cells in which people are being held. The people in these seven cells have long been tortured in human form. Even if they are released, they are probably not far from death. What disappointed Kakashi was that there was no Swain among the seven.

Allen had already described Swain's appearance in detail to Kakashi.

Just when Kakashi wanted to leave the boulder prison, he suddenly stuttered, and then lay on the ground, pressing his ears against the ground.

The ninja's hearing is extremely keen. Just now, Kakashi vaguely heard a faint movement from the ground.

After pressing his ears to the ground, the underground voice became clear. It was a sound mixed with screams and laughter.

There are people underground!

Kakashi's eyes narrowed slightly, Swain, will he be imprisoned in the underground of this prison?

"DaDa, DaDa..."

There was a sound of footsteps, and the two guards in the jail walked in the direction where Kakashi was.

Kakashi's eyes flashed brightly, and it was just time!

Kakashi leaped lightly and jumped to the top of the prison, his back pressed against the roof, his body pressed against the wall like a gecko, his sharp eyes staring down.

Two guards in blue armor came, and they talked as they walked, not even noticing Kakashi above their heads. When the two walked directly under Kakashi, Kakashi jumped off their heads and fell behind them lightly.

Until now, the two guards hadn't even noticed the existence of Kakashi.

When the Kakashi was in the air, his right hand had already pulled out a kunai from his body. After landing, his left hand hit the left guard's back with a knife on the back of the neck. Hearing a click, the cervical spine of the guard on the left was crushed by Kakashi's hand knife.

"thump!"

The guard fell to the ground, without the slightest breath.

While killing the guard on the left, Kakashi, which Kakashi was holding in his right hand, was already gently resting on the aorta in the neck of the guard on the right.

"If you don't want to die, don't say anything."

Kakashi stood behind the guard and said softly.

This guard was also a person who was afraid of death. Hearing Kakashi's words, he did not dare to move at all.

"Where is the passage to the underground, take me over." Kakashi said.

The guard nodded stiffly: "Just ahead."

After speaking, walked forward with Kakashi.

After walking for a certain distance, at the corner ahead, footsteps were heard again, and other guards were walking towards this side!

The guard held by Kakashi turned his head and glanced at Kakashi with a horrified look, fearing that Kakashi would kill himself in order to avoid the guard in front.

"Don't be afraid, keep going." Kakashi said.

At the corner, the two guards turned around and were taken aback when they saw Kakashi and the guard held by Kakashi suddenly appearing in front of them.

At this moment of their stupefaction, the two shurikens in Kakashi's hand had already been shot.

The shuriken directly hit the throats of the two of them, their eyes widened, and they fell straight to the ground.

"quick!"

After killing the two guards, Kakashi urged. I have already killed three guards, and the bodies of these guards will be found at any time, so I must speed up the action!

Seeing Kakashi once again killed his two companions while waving his hands, the guards who were held captive became even more frightened, and trembled with Kakashi and walked forward.

This masked guy is simply a killer!

Turning around two corners, a dead end appeared in front of Kakashi.

"Yes, just ahead."

The guard finished speaking tremblingly, and stepped forward and pressed a button.

"Kacha, Kacha..."

The ground in front slowly cracked open, revealing a ladder leading to the ground.

"This is the gateway to the dungeon." The guard said.

Kakashi nodded slightly, and lightly touched the kunai that had been resting on the guard's neck.

Kuwu crossed the guard's throat, blood gushing out.

The guard covered his wound tightly with his hands, but it was of no avail. He looked at Kakashi with mixed emotions of hatred, fear, and doubt, as if asking.

I have brought you here, why kill me?

The guard's body fell to the ground, Kakashi didn't even look at it, and went straight into the passage.

Ninjas will never be merciful to enemies, even enemies that have already surrendered.

"Who is up there? What's the matter with opening the passage?"

At the bottom of the stairs, a voice asked. Under normal circumstances, the guards above are not allowed to enter the underground prison unless there is an emergency.

At the bottom of the stairs, there were two guards guarding it, and it was one of them who asked loudly.

"it's me."

Kakashi lowered his voice, imitating the voice of the guard he had held before.

The following two guards are obviously familiar with the voice of this guard. After hearing Kakashi's words, he laughed and cursed: "What are you doing here, kid?"

As soon as the two of them relaxed their vigilance, Kakashi suddenly accelerated and rushed down the stairs. After seeing the two at the bottom of the stairs, he threw out two shurikens.

"Whizzing!"

The shuriken plunged directly into the throats of the two guards, and the two guards were killed before they knew what had happened.

After eliminating the two guards, Kakashi moved on.

Along the way, every guard who encountered Kakashi was silently killed by Kakashi. What surprised Kakashi was that this dungeon prison was much larger than the megalithic prison above, making people feel that the dungeon prison was the real prison, and the megalithic prison above was just a cover-up.

In other words, the megalithic prison is just the entrance to the dungeon prison.

In front, a scream came, and Kakashi knew that the cell area was in front. If Swain was imprisoned in this prison alive, it is likely to be in this area.

Quietly approaching the outermost cell, Kakashi hides in the corner and looks into the cell.

In the cell, an unkempt person was chained to his limbs, and the whole person was hung in the air half a meter above the ground in a large font.

In front of this person, two guards talked and laughed loudly. One of the guards used a sharp knife to cut the skin of the locked person.

The guards cut very shallowly and could not cause fatal injuries, but cut one after another, and the locked person was dripping with blood, like a blood man.

Every time the knife was cut, the locked person would let out a painful cry, and he no longer had the strength to scream.

In addition to new injuries, the chained person was also covered with scars all over his body. Obviously, it was not the first time that he had received this torture.

"Why, don't you still want to say?"

Another guard walked up to the locked person with a basin of water and asked with a smile.

Looking at the water basin held by the guard, the eyes of the locked person showed extreme fear.

"I don't know, I really don't know. Please, kill me, kill me!"

The guard chuckled: "I want to die before things are explained? How can there be such a cheap thing in the world."

As he said, the guard poured the water in his hand on the person who was locked up.

"what……"

The chained person let out a scream, the whole body trembles violently, the chain is rustling, and the whole person's facial features begin to twist, showing an extremely painful look.

"Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhāh

The screams made people horrified.

Obviously, the water that the guard poured was added material, otherwise the people who were locked up would not suffer so much.

Kakashi looked at it for a while, found a gap that the guards were not paying attention to, and walked past the door of the cell.

As for saving this stranger, he didn't have the slightest interest.

Kakashi passed through cell after cell. Almost every cell in the underground prison contained people. Some of these detainees were falling asleep, some were alone in a daze, and some were being detained. The guards tortured severely.

The only thing in common is that these detainees are scarred and tortured.

There were no guards patrolling on the road. Kakashi only needed to avoid the sight of the guards who were torturing the detainees in the cell along the way, without encountering any trouble.

Walking to the depths of the dungeon prison, Kakashi suddenly heard a chaotic sound of birdsong, which made Kakashi a little puzzled. Could it be that there are still people in this dungeon prison who have leisure and elegance to raise birds?
