Itachi's Illness

Uchiha compound, deep in the night.

Xingye was in his study researching intelligence on the Akatsuki, when he suddenly heard hurried footsteps outside.

Itachi pushed the door open, his face pale, fine beads of sweat dotting his forehead.

"Brother," Itachi said, "my condition... has worsened again."

Xingye's pupils constricted, and he quickly rose to steady Itachi.

"Itachi, how are you feeling?"

Itachi gave a bitter smile: "My chest hurts, and I'm coughing up more blood."

"The doctor said this is a side effect of the Mangekyo Sharingan and cannot be cured."

Xingye was silent for a moment, then said: "Itachi, sit down."

"I will treat you."

Itachi was stunned: "Brother, can you treat the side effects of the Mangekyo?"

Xingye nodded: "I have a system, and the system's medical capabilities far exceed ordinary Medical Ninjutsu."

"Furthermore, I previously obtained some medical experience from Orochimaru."

"Let me try."

Itachi hesitated for a moment, then finally sat down.

Xingye placed his palm on Itachi's chest, and the healing power of his Otsutsuki bloodline began to activate.

The Byakugan scanned Itachi's physical condition in 360 degrees, searching for the source of the ailment.

In the vision of the Byakugan, Itachi's lungs and heart were severely damaged.

The side effects of the Mangekyo Sharingan were slowly destroying Itachi's body.

"Found it," Xingye muttered to himself.

The Mangekyo Sharingan slowly activated, and Xingye injected chakra into Itachi's body.

The healing power of the Otsutsuki bloodline, combined with the Chakra Control of the Mangekyo Sharingan, began to repair Itachi's damaged organs.

A moment later, Itachi's breathing gradually steadied, and his complexion began to improve.

"Brother," Itachi said in surprise, "I feel... much better."

Xingye said: "It is not fully cured yet; we need to continue the treatment."

"Itachi, although your condition is serious, it is not incurable."

"As long as you cooperate with my treatment, you will definitely make a full recovery."

Gratitude flickered in Itachi's eyes: "Brother, thank you."

"I thought I would die young, just like in the original story."

Xingye said: "That won't happen, Itachi."

"With me here, you will not die young."

"Besides, you still have Sasuke, and the entire Uchiha clan needs you."

Itachi nodded: "Brother, I will cooperate with the treatment."

Xingye continued the treatment until Itachi's condition stabilized.

"Itachi," Xingye said, "for the next month, you need to rest."

"Do not overuse the Sharingan, and do not participate in combat."

"Once I have completely cured your condition, you may resume normal activities."

Itachi nodded: "Understood, Brother."

Xingye continued: "Also, Itachi, I have a plan."

Itachi: "What plan?"

Xingye said: "I will use the system to completely cure your Mangekyo side effects."

"At the same time, I will help you evolve your Mangekyo Sharingan into the Eternal Mangekyo Sharingan."

Itachi's pupils constricted: "Eternal Mangekyo Sharingan?"

Xingye nodded: "That's right."

"The Eternal Mangekyo Sharingan has no Mangekyo side effects and possesses even greater power."

"If you can obtain the Eternal Mangekyo Sharingan, your strength will increase significantly."

Itachi pondered for a moment, then said: "Brother, the Eternal Mangekyo Sharingan requires the eyes of a relative..."

Xingye shook his head: "It does not."

"With the help of the system, I can help you obtain the Eternal Mangekyo Sharingan through other means."

"There is no need to harm anyone."

A glimmer of hope flashed in Itachi's eyes: "Really?"

Xingye nodded: "Of course."

"Itachi, rest assured, I won't let you become the tragic character from the original story."

"You will become one of the Uchiha Twin Stars, leading the Uchiha clan alongside Sasuke."

Gratitude shimmered in Itachi's eyes: "Brother, thank you."

If it weren't for you, I might have already walked down a path of tragedy.

Xingye said: "Itachi, we are brothers; helping each other is only natural."

"Besides, your strength is vital to the Uchiha clan."

"Only when you are fully recovered can the Uchiha Twin Stars truly be formed."

Itachi nodded: "Brother, I will recover as quickly as possible."

Xingye said: "Itachi, get some rest."

"For the next little while, I will focus all my efforts on treating your illness."

"Once you are healed, we still have important tasks to complete."

Itachi: "What tasks?"

Xingye said: "Subdue the Six Paths of Pain and expose the conspiracy of Black Zetsu."

"Only by defeating the Six Paths of Pain can the threat of the Akatsuki be significantly reduced."

A spark of fighting spirit flashed in Itachi's eyes: "Brother, I will cooperate with you fully."

Xingye nodded: "Very good, Itachi."

"For now, get some rest."

Itachi lay down and quickly drifted off to sleep.

Xingye looked at Itachi's sleeping face, making a silent resolution in his heart.

Itachi, I will definitely ensure your complete recovery.

You will not become the tragedy of the original story; you will become the new hope of the Uchiha.

Xingye walked out of the room and arrived at the high platform within the Uchiha compound.

The night sky was dotted with stars.

Xingye looked up at the sky, contemplating his next plans.

"Itachi's condition is improving," Xingye muttered to himself, "This is good news."

"Next, I need to continue subduing the members of the Akatsuki while strengthening the defenses of Konoha."

"The Akatsuki will not give up easily; the battles to come will be even more intense."

Just then, the system's notification sound rang out.

[System Notification: Treated Itachi's illness, gained Medical Ninjutsu experience]

[Medical Ninjutsu (Blue) → Medical Ninjutsu (Purple)]

[Obtained new skill: Healing Technique (Red)]

Xingye felt a surge of joy; his Medical Ninjutsu had upgraded to the purple tier, and he had even obtained the red-tier Healing Technique.

"With the Healing Technique," Xingye muttered to himself, "I can treat Itachi's illness even better."

"At the same time, I can also help others who are in need of treatment."

Xingye turned around and returned to the study.

He needed to continue researching intelligence on the Akatsuki and formulate a detailed battle plan.

The threat of the Akatsuki, while formidable, was not invincible.

As long as he had sufficient preparation and strength, Xingye was confident he could completely dismantle the Akatsuki.

The next day.

Xingye continued to treat Itachi's illness.

With the help of the system, Itachi's condition improved every day.

A week later, Itachi's condition had basically stabilized, and the side effects of the Mangekyo were effectively under control.

Itachi was able to move around normally, though he could not overuse his Sharingan.

Xingye told Itachi that in another month, his illness would be completely cured.

Itachi was filled with gratitude toward Xingye and expressed that he would cooperate fully with Xingye's treatment.

Xingye was also happy, for he knew that Itachi's recovery was crucial for the Uchiha clan.

The Uchiha Twin Stars—Xingye and Itachi—only when both were healthy could the Uchiha clan truly rise.

At the same time, Xingye also continued to secretly subdue members of the Akatsuki.

According to the intelligence provided by Kisame, Sasori, Kakuzu, Konan, and Zabuza, the next target should be the Six Paths of Pain.

The Six Paths of Pain possess the Rinnegan; they are the strongest combat force of the Akatsuki and the most difficult opponents to subdue.

However, Xingye has already made full preparations.

He has the help of the system, the 360-degree vision of the Byakugan, and the powerful abilities of the Mangekyo Sharingan.

Furthermore, he has insiders such as Kisame, Sasori, Kakuzu, Konan, and Zabuza.

The Six Paths of Pain will be subdued by Xingye.

Xingye stood on a high platform in the Uchiha clan grounds, gazing at the distant sky.

"Six Paths of Pain," Xingye muttered to himself, "your doomsday is approaching."

"The threat of the Akatsuki will be completely dismantled."

Xingye turned around and returned to his study.

He needs to continue formulating a detailed battle plan to prepare for the confrontation with the Six Paths of Pain.
