Mangekyo Sharingan

In a shadow that Li Yu had overlooked, Danzo's figure materialized, unscathed, though one of the Sharingan embedded in his arm had permanently closed.

Having been knocked unconscious, Danzo had been jolted awake by the pain of having his Sharingan gouged out; he had immediately activated Izanagi, successfully deceiving Li Yu to save his own life.

Danzo's face was etched with lingering fear, but he soon clenched his fist, his voice laced with fury.

"Senju Nawaki, you are formidable. Just you wait."

Once Danzo calmed down, his gaze turned even more frigid.

"It seems I must find another, more secluded place to hide."

The Anbu and Root ninja, having detected the massive disturbance, arrived just in time to surround Danzo.

"Lord Danzo, are you alright?"

"Where did the enemy go?"

Danzo pondered for a moment before replying, "The person has already fled; it was a ninja from an enemy nation."

"I will report the specific details to the Third Hokage personally."

After dismissing the Anbu, he left with his Root subordinates.

Li Yu could never have imagined that Danzo had survived. His own appearance had triggered a butterfly effect, accelerating Orochimaru's research and leading to the early transplantation of Hashirama Cells and Sharingan into Danzo's arm. The procedure had been so perfect that the transplanted limb showed no abnormalities.

Unlike the original timeline, Danzo's arm was not wrapped in bandages; it appeared as a normal limb hidden beneath his long sleeves, showing no signs of irregularity, which had led Li Yu to misjudge the situation.

Having returned home via the Flying Thunder God, Li Yu was still unaware that Danzo lived, and he happily pulled out the Mangekyo Sharingan soaking in liquid.

He could finally possess his own Mangekyo, though he did not yet know what its ability was, and he wanted to avoid any complications that might arise from delay.

He went to his laboratory, drew a rune array on the floor, and sat in the center.

He immediately activated his Sharingan, the three black tomoe spinning within. He aimed his left eye at the Mangekyo Sharingan and quickly formed hand seals.

A cool, comfortable sensation washed over Li Yu's left eye. The three black tomoe increased their rotation speed until they suddenly merged, spreading out to form a triangular shuriken shape. The Sharingan in the bottle faded into an ordinary eye.

A sharp, stabbing pain suddenly struck his left eye, drawing a small amount of blood, but thanks to the powerful recovery of the Senju Clan, the pain vanished in an instant.

Li Yu suddenly realized that the sensation of the Mangekyo in his left eye was incomparable to that of his right; the sheer power of the ocular chakra was on an entirely different level.

After testing his eye, Li Yu discovered he had gained Kamui, the same ability as Obito.

It was the most bizarre Mangekyo Sharingan in the ninja world, capable of phasing the body, teleporting through space, storing objects in a massive pocket dimension, and shunting parts of an opponent into that same void.

Coupled with his own immense vitality, he could use the Mangekyo infinitely without the risk of going blind, just like Obito.

"I won't even need to maintain Sage Mode or carry giant scrolls anymore."

"My shadow clones can just absorb natural energy within the pocket dimension. Since the space is connected to my own body, I can dispel the clones at any time."

"Mother, I never have to worry about running out of natural energy in Sage Mode again."

After familiarizing himself with the Mangekyo's abilities, he deactivated his Sharingan and prepared to rest.

Li Yu suddenly noticed that the Sharingan in his left eye had reverted from the Mangekyo back to the three-tomoe state and stopped there.

"So, there's this side effect right after awakening the Mangekyo."

"My body hasn't adapted to it yet."

He took off his forehead protector and covered his left eye, feeling quite like Kakashi—the Copy Ninja, Senju Nawaki.

The next day.

Danzo went to find Orochimaru.

"Lord Danzo, what wind blows you to my humble abode?"

"Oh? What happened to your right eye, Lord Danzo?"

Danzo said, exasperated, "It's all thanks to that fine disciple of yours; he snatched that eye right out of my head."

As he spoke, his right eye still throbbed with lingering pain.

"Find me another Sharingan to replace it, and help me replace the one on my arm as well."

"Oh? It seems, Lord Danzo, that you had to use Izanagi to escape with your life."

"Has my disciple truly become that formidable?"

"Hmph, enough nonsense. Find me eyes to replace these."

Seeing the expression on Danzo's face, Orochimaru already understood the situation.

He retrieved a three-tomoe and a two-tomoe Sharingan, installing them for Danzo respectively.

Before leaving, Danzo said, "Keep your human experiments low-key for a while; the Anbu patrols in the village have tightened."

"But rest assured, I will provide even more experimental materials—only more, never less."

Watching Danzo leave his secret laboratory, Orochimaru muttered to himself, "Nawaki, I never expected the experiment from all those years ago to be so successful. I have never managed to replicate it since."

"Could it be because you are of the Senju Clan?"

"I still prefer to believe in the genetic issues you mentioned back then."

"Through my years of observation, the fact that you, Nawaki, can freely deactivate your Sharingan further proves the importance of genetics."

After saying this, Orochimaru buried his head back into his research.

Danzo emerged from Orochimaru's base and made a secret trip to the Hokage Office Building.

"Danzo, you've come."

"What exactly happened yesterday?"

"The enemy village's spy has already been eliminated by me; I will now go into hiding."

After speaking, Danzo quickly left the Hokage Office Building, as if afraid of running into someone, even though he was heavily cloaked.
