The next day, Tsunade began teaching Izumi the basics.
"First, you need to understand the body's acupoints and meridians, but you have the Sharingan, so I don't need to teach you that. Next will be medical knowledge…"
A few days later, Shizune watched in shock as Izumi performed surgery on an injured puppy.
Izumi focused intently on the surgery, and as soon as it was completed, she immediately used Medical Ninjutsu, and the puppy quickly sprang back to life, running around energetically.
Shizune swallowed and said, "No wonder Lady Tsunade values her so much. I thought it was already impressive that she learned those difficult Ninjutsu so quickly, but I never expected her to pick up surgery so fast and learn it so quickly!"
Shizune looked at the now vibrant animal and praised her, "That's excellent. Next, it's human experimentation. Are you ready?"
Izumi nodded gravely, "Yes! I'm ready."
"Um…" Izumi suddenly asked, "What if I can't cure them? Will it cause trouble for you?"
"Of course not!" Shizune said with a cold smile, "They're just death row inmates. This Daimyo received Lady Tsunade's favor in the past, so Lady Tsunade can make any request, and of course, he has many death row prisoners here."
"Oh, I understand." Since they were death row inmates, Izumi felt relieved.
Izumi followed Shizune to a Daimyo's territory, and the two walked into the gloomy dungeon.
The prisoners on both sides saw the two of them and their eyes immediately glowed green: "Yo, it's a little lady! Haven't seen a woman in a long time!"
"Shh~ Little lady, you're quite pretty. Come here!"
"Hehehe!"
"This little girl isn't even an adult yet, but she's already so cute. What will she be like when she grows up?! Hehe…"
"The older one isn't bad either; she's at her prime, slurp."
Upon hearing this, Shizune immediately stopped and looked at the death row inmate.
"Huh? Are you lonely? Do you want to do that with me? Hehe, no problem, just let me out first… What are you doing?"
The death row inmate watched as Shizune coldly smiled, opened the cell door, and walked in.
His eyes narrowed, and he immediately charged at Shizune, intending to knock her down and rush out of the cell.
But with a gentle wave of Shizune's hand, a Chakra Scalpel directly cut a deep wound into his body.
"Ah!" The death row inmate clutched his wound and screamed. Shizune continued to look at him indifferently.
"Ninja! She's a Ninja!" The surrounding death row inmates immediately shouted, and then one by one, they all quieted down.
"This one!" Shizune told the guard, then dragged him by the foot across the ground.
As she dragged him, she said, "I've cut his body and some of his internal organs. I controlled it very well; he won't die for a short time. Next, I'm going to teach you how to precisely repair internal organs! This is delicate work!"
"Yes!" Izumi excitedly looked at the death row inmate on the ground, and couldn't help but feel a sense of anticipation.
The death row inmate looked at the two of them, who were observing him like an item, and he despaired: "What's wrong with these two people? Aren't women supposed to be gentle?"
"No, I don't want to go out anymore, stop, stop…"
"Boom!" The door closed. All the death row inmates were now quiet; not a single one dared to make a sound.
So, these days, Izumi had been performing surgery on those death row inmates.
Every time Shizune and Izumi arrived, the death row inmates immediately huddled in a corner, bowing their heads deeply, terrified of being dragged out.
Because no one who was taken out had ever returned.
This time, Shizune walked up to a man who had been full of vulgarities in the past but was now very well-behaved. Shizune directly kicked him in the leg.
"Crack!" The man's leg instantly bent.
"Ah!" He cried out in pain, clutching his leg.
"This time, I'll teach you how to repair severely damaged and most troublesome bone injuries. We can usually heal ordinary bones with Medical Ninjutsu, but I used a bit of force just now, and quite a few small fragments broke off. You need to pick them all out. As long as you can pick them out and restore his leg to its original state, then you'll be a top-tier Medical Ninja."
"Yes!"
A long time later, Izumi wiped the sweat from her forehead and said, "Failed!"
Shizune smiled, "It's okay, I haven't succeeded yet either!"
She patted Izumi's shoulder and said, "If you succeed, you'll be able to compare with Lady Tsunade!"
"Hehe, um, Senior Sister Shizune, I want to try again."
"Oh? Oh, I see." Shizune walked towards the man.
The man looked at Shizune in terror as she raised her foot, and then, in his frightened gaze, Shizune stomped down on his other leg.
"Crack!"
"Ah!!!!…"
…
"Failed again!"
A few days later, Izumi, with trembling hands, high-fived Shizune and said, "I did it! I finally did it! Yay!"
"That's great, Izumi! As long as you keep practicing, these surgeries will be second nature to you!"
"Mm! Thank you, Senior Sister! I'll try again!"
"Huh? This is very draining. Aren't you going to rest?"
"Hehe, I'm from the Senju Clan; I have plenty of energy!"
"Alright, then you do it yourself! I'm going to rest."
"Mm!"
Izumi walked up to the man, and under his terrified gaze, she suddenly smiled innocently.
"Hiss, no—"
Izumi stomped on his arm.
"Ah!"
…
"Ah! Failed again!"
Izumi lay on the bed, staring at the ceiling, and said, "It's so hard!"
These past few days, she had been thinking about how to handle this type of surgery. One night, Izumi suddenly thought, "I remember there was a technique in Hunter x Hunter that used Chakra threads, what was it called? Chakra Thread Stitching! I'll try it then!"
A few days later, Tsunade watched with disgust as Izumi manipulated the extremely fine Chakra threads on her palm to stitch up the prisoner's arm. She thought in shock, "This works too? How much precision does this require? Muscles, even smaller nerves can be connected. It's incredible, ugh—"
"Huh? These fine Chakra threads can also remove debris and bone fragments from vital organs? That's too amazing! Ugh…"
Shizune also said, "Right? See, she actually uses those fine Chakra threads for surgery and stitching, stitching and healing at the same time. How much calculation and precise manipulation does that require?"
"Ugh…"
"Lady Tsunade!" Shizune immediately supported Tsunade.
Tsunade watched the prisoner freely move his arm, then looked at the fine Chakra threads in Uchiha Izumi's palm. Each Chakra thread was the green Chakra of Medical Ninjutsu.
Izumi's Chakra-formed threads moved without any obstruction. She pondered in shock whether she should try to learn it herself in the future, though she might not be able to.
"Indeed, the same Ninjutsu has different uses in different people's hands."
After the surgery, Tsunade told her, "You can graduate. Congratulations."
"Yay! Thank you, Lady Tsunade!" Izumi happily treated them to a big meal.
During this time, Izumi treated them to big meals every day, making them a little embarrassed, but Izumi said she was very rich, so they relaxed.
"Wuwuwu… Izumi, if you leave, I'll be subjected to Lady Tsunade again… Ah!" Shizune covered her head and looked at Tsunade.
Tsunade crossed her arms and snorted, "Hmph, talkative!"
Tsunade told Izumi, "Izumi, you are the most talented student I have ever seen. As my clan member, the honor of revitalizing the Senju Clan is entrusted to you!"
"Yes! Lady Tsunade! I will revitalize both the Uchiha and Senju Clans, and I will also make Konoha the strongest Ninja Village!"
"Mm!"
Finally, Tsunade and Shizune watched Izumi's retreating back. Shizune asked, "So young and so talented, and also very hardworking, intelligent, and beautiful. I'm truly envious."
Tsunade sighed, "Alas, her future will definitely not be satisfied by just being a Hokage. If she stays on the right path, revitalizing Konoha will absolutely not be a problem. If she goes down the wrong path, then she will be a great enemy to the entire Ninja World. Moreover, she is also from the Uchiha Clan; this family is a particularly extreme clan."
"Huh?" Shizune looked at Tsunade in confusion and asked, "If that's the case, then why did you teach her?"
Tsunade smiled and said, "I just couldn't resist. I want to see what kind of person she will become in the future. Besides, she also has the bloodline of the Senju Clan, and she paid tuition, so I had even less reason to refuse."
"…" Shizune looked at Tsunade, then looked at Uchiha Izumi's vanished back. The moment she turned around, she found that Tsunade had already run off, carrying the money box.
"Ah! Lady Tsunade, just let me hold the money!" Shizune immediately chased after her.
