As night falls, the silhouette of Hozuki Castle looks particularly eerie in the moonlight.
Naruto, Sasuke, and Yuki-onna stood on the hillside five hundred meters away from the city wall, looking at the prison shrouded in darkness.
"It feels wrong." Naruto frowned, "There's no sound at all Hozuki Castle."
Sasuke's Rinnegan carefully observed around the city wall. "It's not that there is no sound, it's that the sound is blocked by some kind of force. Look at the patrolling guards, their mouths are moving, but you can't hear any conversation."
Yuki-onna closed her eyes, and the perception ability brought by Ice Release Kekkei Genkai was fully activated. After a moment, she opened her eyes, her face solemn.
"The entire city is wrapped in a special energy field, which is the 'Soundless Wall' mentioned by Nagato."
"How thick?" Sasuke asked.
"At least thirty meters." Yuki-onna stretched out his hand, and tiny ice crystals condensed in the air, "And this energy field not only blocks sound, but also continues to absorb the surrounding Chakra."
Naruto moved his wrist. "Then just break in."
"Wait." Sasuke stopped him, "Entering rashly may trigger the alarm. I'll test it with Heavenly Hand Power first."
He picked up a stone from the ground, activated his Rinnegan Eye Power, and the stone disappeared instantly and appeared on the inside of the city wall.
The three of them waited with bated breath, but the expected alarm did not sound.
"It seems that space teleportation will not trigger the defense mechanism." Sasuke breathed a sigh of relief.
"Then let's teleport in directly?" Naruto suggested.
Yuki-onna shook his head. "No, Heavenly Hand Power's distance is limited, and Sasuke's pupil power needs to be preserved. Who knows what traps there are."
"Then go through the main entrance." Naruto grinned, "I enter Sage Mode, Natural Energy shouldn't be absorbed."
The three of them discussed their strategy and began to approach Hozuki Castle.
The closer to the city wall, the stronger the strange feeling of silence became. Naruto tried to speak, but the sound disappeared the moment it came into contact with Soundless Wall, and even he could not hear it.
Sasuke gestured to continue moving forward.
The moment they passed through Soundless Wall, the three of them felt dizzy at the same time. The world around them became extremely quiet, even the sound of the wind disappeared, leaving only the sound of their own heartbeats echoing in their ears.
Naruto opened his mouth to say something, but found that no sound came out at all. He looked at Sasuke and Yuki-onna in horror. They obviously encountered the same problem.
Sasuke quickly uses hand gestures to communicate: stay alert and move toward the goal.
The three of them walked carefully through the outer courtyard. The patrolling guards were walking not far away, but their footsteps and breathing sounds disappeared, and the whole scene was weird like a silent movie.
Suddenly, Naruto's Sage Mode felt a killing intent. He turned around suddenly, but saw nothing.
Sasuke's Rinnegan scanned the surroundings and found nothing unusual.
At this moment, a black shadow jumped out from the darkness, and the blade in his hand pierced Naruto's back heart.
"Be careful!" Yuki-onna wanted to shout, but couldn't make any sound. She could only use the fastest speed to form an ice wall to block behind Naruto.
The blade pierced the ice wall and drew a bloody mark on Naruto's shoulder.
Naruto rolled to avoid it, and then he saw the appearance of the attacker clearly - it was a prisoner covered in bandages, with empty eyes, and exuding the unique mechanical aura of Cyborg.
Sasuke pulled out Kusanagi Sword and slashed at the prisoner with a sword. However, the opponent's reaction speed was astonishingly fast. He turned sideways to avoid the attack and slashed Sasuke's neck with his backhand.
Yuki-onna With both hands Hand Seals, the ice-crystalized right arm was waved out, knocking the prisoner back.
The three of them stood back to back, observing their surroundings vigilantly.
More black shadows emerged from the darkness, and at least twenty reformed prisoners surrounded them. The movements of these prisoners were completely silent, and even when they were hit and fell to the ground, no sound was heard.
Naruto gritted his teeth and entered Nine-Tails Chakra Mode. The golden Chakra Cloak emerged, but the moment it came into contact with the Soundless Wall energy field, it was heavily absorbed and the light became dim.
"Damn it!" Naruto cursed in his heart, Nine-Tails's power was suppressed by at least 50%.
Sasuke's situation is not optimistic either. Although Rinnegan's insight is still there, there is no warning at all for the attacks of these prisoners. There is neither Chakra Wave movement nor subtle changes in muscle tension, making it impossible to prevent them.
A prisoner made a sneak attack from the side, and Sasuke was almost hit in the vital part, so he could only use Heavenly Hand Power to forcefully change his position. However, the eye power was consumed much faster than expected.
Yuki-onna's Ice Release was not greatly affected, but facing so many enemies, she could only barely defend.
The battle reached a stalemate.
Just when the three of them were tired of dealing with it, a black shadow suddenly fell from the sky, aiming directly at Yuki-onna.
Sasuke wanted to use Heavenly Hand Power to rescue, but the eye power had been consumed too much, and the movement was half a beat slow.
Just as the attack was about to hit, a Red Chakra chain shot out from the side and entangled the attacker.
Karin jumped out of the shadows, with a pale face but firm eyes. She was supposed to stay on the outside to respond, but seeing the three of them in danger, she ventured into Soundless Wall.
Naruto was surprised and happy when he saw Karin. He wanted to say something, but couldn't make a sound, so he could only use gestures to signal her to leave quickly.
Karin shook his head, bit his fingers, and drew complicated Fuinjutsu patterns on the ground.
That is the unique perception seal of the Uzumaki Clan, which can establish Chakra connection in a silent environment, allowing teammates to communicate with each other simply.
The moment Cursed Mark was completed, the consciousnesses of the four people were connected together.
"I can finally 'speak'." Naruto breathed a sigh of relief.
"Karin, you shouldn't have come in." Sasuke frowned.
"Stop talking nonsense, let's find a way to break out first." Karin gasped, maintaining the Fuinjutsu posture was very exhausting.
Yuki-onna's voice sounded in his consciousness, "I sense the energy Node of Soundless Wall, which is in the tower on the east side of the city wall. As long as Node is destroyed, this energy field will be ineffective."
"Then what are you waiting for?" Naruto was about to rush out.
"Wait." Sasuke stopped him, "Node's position must be heavily guarded, and our current situation..."
Before he finished speaking, the encirclement suddenly shrank. The reformed prisoners launched an even more violent offensive, completely ignoring their own safety and rushing towards the four people without fear of death.
One prisoner hugged Naruto's legs, and the other took the opportunity to slash at his neck with a knife. Naruto used Rasengan to fight off the second prisoner, but the first prisoner refused to let go and refused to let go despite being hit by Rasengan.
"These guys are not afraid of death at all!" Naruto was shocked.
Sasuke cut off the arms of three prisoners, but they still bit them with their teeth and hit them with their bodies, feeling no pain at all.
Yuki-onna's Ice Release froze five prisoners, but more enemies emerged from the shadows, and the number could not be killed at all.
Karin gritted her teeth and maintained the Fuinjutsu posture, but a prisoner broke through the defense line and pierced her shoulder with a knife.
