Heart Disease + Bloodline Disease

The next morning, sunlight filtered through the curtains into a hospital room at Konoha Hospital, while the faint scent of disinfectant lingered in the air.

Uchiha Itachi sat on the hospital bed as Tsunade stood before him, carefully conducting a series of examinations.

Originally, Uchiha Itachi had utterly disdained this sort of examination. He felt that there was nothing wrong with him at all.

However, he ultimately could not resist Uchiha Feng forcibly dragging him here.

At that moment, Uchiha Feng paced back and forth outside the room, his face carrying a hint of anxiety.

Time slowly passed. The morning light gradually gave way to the noon sun, yet the atmosphere outside the hospital room remained tense.

Uchiha Feng wandered anxiously through the corridor, his brows tightly furrowed as he muttered, "Why isn't he out yet? Is Tsunade really any good? It's just a medical examination—how could it take this long?!"

Jiraiya, on the other hand, looked entirely calm. Smiling faintly, he tried to soothe Uchiha Feng's worries. "Don't worry. Tsunade is the strongest medical ninja! No one can match her medical skills. She'll definitely handle it properly."

Just then, the hospital room door slowly opened, and Uchiha Itachi stepped out. A faint smile rested on his face, though a trace of exhaustion showed in his expression.

Seeing this, Uchiha Feng hurried forward and asked with concern, "Little brother, how do you feel?"

Uchiha Itachi raised his brows, determination flashing in his eyes. "I'm fine! It's nothing. Brother, I still have a mission to carry out today, so I have to go first."

Although Uchiha Feng was puzzled, he nodded understandingly. "All right! Go ahead, then. Be careful."

Uchiha Itachi smiled slightly and gave his brother a reassuring look before turning and leaving Konoha Hospital.

His figure gradually disappeared beneath the sunlight...

Just then, Tsunade's voice came from inside the room. "Uchiha brat, come in here alone!"

Hearing that, Uchiha Feng frowned slightly. He felt a vague unease in his heart, but he still stepped into the room.

Tsunade came into view, seated at the table with a pen in hand. She was intently jotting something down in a thick notebook at great speed, her brows faintly furrowed in deep concentration.

When she noticed Uchiha Feng entering, she raised her head without any politeness and said bluntly, "Your little brother does indeed have a problem. It could be serious or minor, but it's very troublesome."

Uchiha Feng's heart immediately sank, and he could not help asking, "What's wrong with him?"

Tsunade frowned slightly, her tone heavy. "He has Bloodline Disease, and he also has congenital heart disease! The combination of the two makes his condition exceptionally complicated."

Uchiha Feng's eyes flickered. After thinking for a moment, he said, "I can understand congenital heart disease, but Bloodline Disease... How could the Uchiha Clan have something like that? I've never heard of it."

Tsunade let out a slight breath of relief and said firmly, "I have a way to cure his heart disease, but the medicine for Bloodline Disease still requires further research and exploration. That may take some time."

Uchiha Itachi's Bloodline Disease appeared simple on the surface, but it concealed deadly danger.

Whenever he used the Sharingan, his body would feel a trace of weakness. Though the feeling was minuscule, if it continued over time, it would gradually accumulate and eventually lead to irreversible consequences.

What was more, every use of the Uchiha Clan's Mangekyo Sharingan would diminish his eyesight a little further. This invisible price was undoubtedly a bottomless pit, one that would ultimately lead only to complete blindness.

Without treatment, the future Uchiha Itachi would not only suffer the torment of Bloodline Disease, but also be plagued by congenital heart disease, making his physical condition even worse.

Tsunade explained it to Uchiha Feng for a long time, her brows tightly knitted. At last, she said solemnly, "Your little brother should not take any more missions for the time being. We'll talk again once I've developed medicine for this Bloodline Disease!"

Uchiha Feng fell into thought, quietly weighing the matter. After a while, he slowly said, "All right! How long will it take to develop the medicine?"

Tsunade said firmly, "I'll return to the village again in one year. During that year, you'd best have your little brother temporarily withdraw from all ninja operations, lest his condition worsen!"

Uchiha Feng nodded, a hint of resolve in his voice. "I understand, Granny Tsunade!"

"Hm? What did you just call me? Granny Tsunade?" Tsunade raised a brow, and her face instantly darkened. "What is it, brat? You called me Lady Tsunade before, but now that you've achieved your goal, you've switched to Granny? Do I look like a granny to you?"

Uchiha Feng froze, then hurriedly explained, "Uh... Granny Tsunade, please don't get worked up. The facts prove that you're indeed not young anymore. As far as I know, you should be forty years old, right?"

Bang! Tsunade showed no mercy as she punched Uchiha Feng. The instant her fist landed, a huge bump immediately rose on his head, making him look so ridiculous that it was hard not to laugh.

"Ow, ow, ow! Damn it! Granny Tsunade, why are you so violent?" Uchiha Feng clutched his head, his eyes full of grievance.

Tsunade glared at him furiously, her tone carrying unquestionable authority. "Brat, you are not allowed to call me Granny, understand? I'm only eighteen this year!"

Her voice carried a stubborn refusal to admit age, as though she were swearing that her youth remained untouched.

"Cough, cough, cough..." Uchiha Feng scratched his head awkwardly, an unnatural flush appearing on his face. "Sorry, sorry, Granny Tsunade. I still have some things to deal with, so I'll be taking my leave! Don't forget to come find me in a year! Hahaha..." His voice sounded somewhat relaxed, though it also carried a trace of haste.

Before he had even finished speaking, Uchiha Feng's figure dissolved into nothing amid a puff of white smoke, vanishing in an instant as though he had never been there.

Tsunade looked in the direction where he had disappeared and could not help shaking her head. "What a brat. It was only a Shadow Clone, and I didn't even notice!"

Meanwhile, within the estate at the Uchiha Clan Compound, Uchiha Feng sat in a spacious main hall, where the atmosphere was solemn and tranquil.

As the son of the Uchiha Clan head, he already possessed an estate of his own. It not only symbolized his status, but also suggested that he might inherit the position of clan head in the future and shoulder greater responsibility for the family.

At that moment, Uchiha Feng sat cross-legged with his eyes slightly closed, focusing on refining the chakra within his body.

His heart was like a vast, turbulent ocean, nurturing boundless power.

Unlike those native Konoha residents, he was a transmigrator, blessed with extraordinary creativity and a unique perspective.

His thoughts seemed to wander through the cracks of time and space, allowing him to analyze the essence of power from different dimensions.

Most importantly, his spiritual power had already reached an astonishing level.

Chakra was the perfect fusion of spiritual energy and physical energy. What he currently lacked was only physical energy.

Although his physical strength was quite outstanding as well, compared to the powerful physiques of the Senju Clan, it still fell somewhat short.
