Shisui has solved the problem.
Shaoyu stood in front of a cave.
The entrance to the cave is hidden between two rock crevices, and is covered with a thick layer of moss and hanging vines. From the outside, it looks like an ordinary mountain fold.
There is no chakra fluctuation, no trace of Barrier Ninjutsu style, and even the air flow is normal.
If he hadn't already known what was here, he would have passed by it a hundred times without giving it a second glance.
He lifted the vines and walked in.
The steps were slow and the landing was silent. The white robe looked like a moving ghost in the darkness of the cave.
The tunnel is very deep and becomes narrower as you go in. The rock walls are covered with a layer of smooth salt frost, and the air is filled with a moist mineral smell and a very faint smell of old age.
When you reach the end of the corridor, you will see a secret door reinforced with Earth Release.
Shaoyu didn't look for the mechanism, he pressed his palm on the door, his chakra shook, the secret door cracked from the middle, and gravel fell down.
Behind the door is an empty cave. The highest point of the dome is three feet high, and the walls are made of rough granite.
There is a stone platform deep in the cave. The stone platform is covered with dark red cushions. Behind the stone platform is a chair cut from rock. The back of the chair is very high, and the top extends slightly curved arcs to both sides.
There is an old man sitting on the chair.
His white hair hangs down to his waist, and his dry skin hangs loosely on his wide frame. Dozens of tubes on his back extend from the spinal joint and sink into the depths of the cave.
The connection point of the pipeline was embedded in his spine, and a layer of gray-white keratin grew at the interface between the skin and the metal.
Uchiha Madara.
"Who are you!"
Sound exploded from the shadows on the ground.
Black Zetsu suddenly emerged from the shadow of the rock wall, its black semi-fluid body condensed into an irregular shape in front of the stone platform, its two round yellow eyes widened, and its pupils shrank into two black dots the size of soybeans.
Its voice was sharp and hoarse, completely different from its usual slow and gloomy tone.
It's panicking.
It has been hidden in this cave for decades, hiding it from the entire Shinobi World and the sensing ninjas of Five Great Shinobi Villages.
No one can be found here.
But now there is a person standing at the entrance of the cave. He is wearing a white robe and Uchiha Gunbai pattern. He is standing there openly, as if he is here to visit.
Black Zetsu's body took a step towards the stone platform. Its mind was spinning rapidly.
It had never sensed the chakra fluctuations of the person in front of it, but it could recognize the Gunbai pattern on that robe.
Uchiha. Uchiha again.
Uchiha Madara is so old that he can't even live without a chair. Once Demonic Statue of the Outer Path's chakra supply is cut off, it will be a dead end.
Eye of the Moon Plan, which has deceived Uchiha Madara's layout for decades, has not yet reached the final step, and its mother has not yet been resurrected. It must not capsize here.
Shaoyu looked at it.
He took out a sealing scroll from his sleeve, unfolded it, the sealing talisman fell, and an eyeball appeared in his palm.
The eyeballs shimmered dark red in the dim light of the cave, and the three-edged sickle-shaped pattern in the pupils slowly rotated.
Mangekyō Sharingan of Obito Uchiha.
He held the eyeball in his palm and poured chakra directly into it.
It is not inserted into the eye socket, there is no need - his hand is the connection point, chakra is directly injected into the optic nerve stump of the eyeball from the meridian in the palm, and the pattern of Mangekyō Sharingan suddenly lights up.
Black Zetsu's yellow eyes suddenly widened.
It didn't know what the ability of that eyeball was, but it instinctively felt something was wrong.
The body quickly sank to the ground, and the black semi-fluid seeped down against the rock wall, preparing to blend into the shadow and escape.
A vortex opened silently in front of it.
Space itself spins like a whirlpool.
The air, dust, the cold air in the cave, and Black Zetsu's entire body that had not had time to sink into the shadow were sucked in by the vortex.
Black Zetsu only had time to let out a short exclamation, but the sound was completely swallowed up by the vortex of space.
Kamui Dimension.
Black Zetsu is standing in a strange space made up of countless cubes.
There is no sky, no ground, just endless gray-white squares extending in all directions.
Then a huge black shadow rose in front of it.
It has three heads and six arms, an eight-hole dharma ring on the top of its head, and six blue eyes overlooking it from a high place. Mahoraga.
Black Zetsu has lived for thousands of years, from the time of Kaguya to the present, but it didn't know this thing before and seemed to have seen it some time ago.
"Are you...Uchiha Shaoyu?"
But it also knows one thing - Mahoraga cannot hurt it. The only one in this world that can hurt it is Yin-Yang Release. It is the product of Otsutsuki Kaguya Clan's will and is a pure embodiment of chakra. Any physical attacks and conventional ninjutsu are ineffective against it.
Mahoraga's giant fist came down and hit Black Zetsu's head.
The black semi-fluid scattered in all directions, then gathered back together after raising his fist, leaving no damage at all.
"It's useless."
Black Zetsu's voice returned to calmness.
"Your shikigami can't hurt me. It's no use trapping me here. Sooner or later I will find a way out."
The magic ring on Mahoraga's head began to rotate.
The eight-hole magic ring rotated slightly faster after the first attack. Adaptation began.
Black Zetsu can't get out.
Kamui Dimension is a different space created by Obito Uchiha's Mangekyō Sharingan pupil technique. Without Obito Uchiha's own Kamui transmission, nothing can come out of it.
There is no upper limit to the adaptability of Mahoraga - give it enough time and number of attacks, and sooner or later it will analyze the immune mechanism of Yin-Yang Release and find a way to break through.
But...
The problem now is not Black Zetsu.
Shaoyu re-sealed Obito Uchiha's eyeball, recovered it, and put it away.
Then he raised his eyes and looked at Uchiha Madara on the stone chair.
The culmination of this Uchiha Clan, the legendary Asura of the Ninja World, Uchiha Madara.
Madara was also looking at him.
Three-Tomoe Sharingan turned slowly in the deep-set eye sockets, and there was no panic in those eyes.
Black Zetsu didn't panic when he was sucked into a different space, and White Zetsu didn't panic when they were cowering in the corner.
He just looked at the intruder and the pair of Mangekyō Sharingan that had the same origin as his, as if looking at something that was too late.
Several White Zetsu leaned half out of the rock wall, and the white human figures huddled together in the corner of the cave. Dozens of pairs of yellow round eyes stared at Shaoyu.
They moved forward half a step, then retracted, then moved half a step forward, then retracted again.
It's not that I don't want to do it, it's that I don't dare.
This man's chakra pressure was too strange and powerful, unlike any ninja they had ever seen.
Moreover, Black Zetsu was taken into a different space by him in just one breath. This strength gap cannot be made up by quantity.
They could only huddle in the corner and tremble, not even daring to breathe.
