Simultaneous traversal: All Abyss difficulty

In the dim dungeon under Konoha Village, the air was filled with damp and moldy smells. The torches on the wall flickered with weak light, casting swaying shadows on the cold stone walls.

Kakuzu was tied up on a stone bed, unable to move, and his memory was being extracted by the Yamanaka clan ninja.

The Yamanaka clan ninja's forehead was covered with fine beads of sweat. He concentrated on invading Kakuzu's mind with chakra, trying to dig out key information from his maze-like complicated memory, especially the information about the mysterious organization "Akatsuki".

However, Kakuzu, as a living fossil of the ninja world, has experienced countless things in his life, and his memory is like a vast ocean. The extraction process is long and difficult.

As time passed, the ninja continued to dig deeper, but he never found the core secrets of "Akatsuki". All he found were trivial memories that were irrelevant.

The ninja sighed helplessly, stretched his waist, and slowly got up.

He rubbed his sore shoulders, turned around, opened the cell door, and walked into the dim corridor.

As soon as he went out, he keenly sensed a strange atmosphere.

The Anbu ninja who usually patrolled the corridor was nowhere to be seen at this moment, and it was a little weird.

His heart was suddenly alarmed, realizing that something big might have happened.

Just then, he saw a man wearing an Anbu cat-faced mask slowly approaching from a distance.

The eyes under the mask flashed with mysterious light, which looked particularly gloomy in the dim environment.

The ninja was about to move when a strong feeling of dizziness suddenly hit him, as if the whole world was spinning.

His legs were weak and his body collapsed uncontrollably!

As the figure gradually approached, the ninja's vision became more and more blurred, but when he tried to raise his head, he saw a picture that terrified him!

In the distance of Konoha Village at night, a huge orange fox was roaring to the sky!

The fox was as huge as a mountain, with powerful and evil chakra emanating from its body, and its eyes flashing with strange red light.

The ninja of the Yamanaka clan instantly realized that he was under an illusion. At this critical moment, he bit his tongue without hesitation and tried to remove the illusion by hurting himself.

However, just as he was about to take further action, he suddenly felt a sharp pain in his head.

Uchiha Yu hit him hard on the head with a punch!

The guy's eyes turned black, and he fainted directly, and his body fell limply to the ground.

With the Observation Haki, Overlord Haki, and the illusion ability of the Mangekyō Sharingan, Uchiha Yu could hide in such a place as easily as going home.

Uchiha Yu walked into the dim room silently, and the air was filled with a disgusting smell of blood and rottenness.

His eyes passed through the darkness and fell on Kakuzu, who was tortured beyond human form in the corner.

Kakuzu's body was bound by layers of chains, and his tattered clothes barely covered his scarred body, with a look of fatigue and pain on his face.

"Sashibuli~ Kakuzu-san." Uchiha Yu's voice broke the silence, as if he was just greeting an old friend he hadn't seen for a long time.

Kakuzu opened his eyes in a daze, and his originally dim eyes suddenly brightened the moment he saw Uchiha Yu, which was the light ignited by anger.

"You damn kid!" He used all his strength to curse loudly, and his voice became hoarse because of anger.

Long-term torture did not wear away his stubbornness, but made his hatred even stronger.

Uchiha Yu didn't care about Kakuzu's curse at all, and the corners of his mouth rose slightly. He slowly pulled open his clothes, and in the weak light, two masks hidden in his body gradually appeared.

Wind escape earth resentment Yu!

Water escape earth resentment Yu!

Kakuzu's eyes widened instantly. The moment he saw the two masks, he felt a surge of blood rushing to his head, and he almost fainted on the spot.

"You, you bastard!" He cursed even louder, with endless anger and unwillingness.

These two masks are the source of his power, but now they are taken by Uchiha Yu. How can he bear it?

Uchiha Yu seemed to have anticipated Kakuzu's reaction. He walked forward slowly and his eyes fell on the only intact lightning mask left on Kakuzu.

"Tell me, where are the other fire and earth masks?"

Kakuzu did not answer, but continued to curse, his words became more and more intense, his eyes were full of hatred, staring at Uchiha Yu, as if he wanted to cut him into pieces with his eyes.

Seeing this, Uchiha Yu shook his head helplessly.

He knew that it was impossible to communicate with Kakuzu at this moment.

He took out two small flying needles from his arms, which flashed coldly in the dim light.

He approached Kakuzu step by step, his eyes revealing a feeling of anticipation before the feast was served.

The two flying needles rubbed left and right, and it looked no different from grinding the barbs on disposable chopsticks.

In Kakuzu's horrified and angry eyes, Uchiha Yu aimed the flying needles at the edge of the lightning mask and stabbed it.

Kakuzu felt a strong sense of uneasiness in his heart. He tried to struggle, but was tightly bound by the iron chain with the nature of sealing chakra, unable to move! This feeling is similar to the devil fruit ability user being tied up by seastone.

As expected, Kakuzu's guess was confirmed!

Uchiha Yu used the flying needles to circle the black lines on the mask, and then began to sew it on himself!

"You lunatic!" Kakuzu shouted in despair. He felt like an octopus watching its tentacles being eaten. His powerlessness and anger reached their peak.

But his shouting seemed so powerless in this dim room. He could only watch Uchiha Yu take away his last symbol of power bit by bit.

As the last stitch was completed, a Thunder Escape and Earth Grudge Mask was firmly on Uchiha Yu's body!

The pattern on the mask fit his skin, and there was a faint flash of lightning.

He slowly raised his head and his eyes fell on Kakuzu again. His eyes were like a predator staring at its prey, full of oppression.

"I ask you again, how did the masks of Fire Escape and Earth Escape disappear?"

Uchiha Yu's voice was low and cold, echoing in this dark and damp dungeon, and every word seemed to be squeezed out from his teeth.

Kakuzu gritted his teeth, said nothing, and his face was full of determination.

His lips trembled slightly because of anger and patience, but he still refused to speak stubbornly, as if to declare to Uchiha Yu that he would rather die than reveal any information.

Uchiha Yu frowned, obviously feeling thorny about Kakuzu's attitude.

He paced back and forth in place, thinking about countermeasures.

The dungeon was silent, with only his heavy footsteps and Kakuzu's heavy breathing.

After a while, Uchiha Yu stopped, and a trace of determination flashed in his eyes.

He took a deep breath, and as the chakra surged, he saw black, wriggling earth resentment Yu coming out of his body, twisting in the air, making a creepy sound!

Kakuzu saw this scene and his expression instantly became tense. He didn't know what Uchiha Yu was going to do, but his instinct told him that what happened next must be terrible.

"Eat him!" Uchiha Yu spat out three words coldly.

When Kakuzu heard this, his heart tightened and he struggled subconsciously, and the iron chain was rustled by him.

However, those earth resentful guards did not speak immediately. Seeing this, Kakuzu breathed a sigh of relief, thinking that he had escaped.

But the next second, the expression on his face suddenly became extremely terrifying.

Uchiha Yu's Sharingan rotated rapidly, emitting a strange red light.

Under the powerful control of the Sharingan, those earth resentful guards seemed to be given new instructions, and they pounced on Kakuzu with their fangs and claws, instantly drowning him.
