Returning to Konoha Ninja Village, Izumi excitedly went to the Ninja tool shop, which was Tenten's family's store.
Izumi watched the little girl, Tenten, who was practicing throwing Kunai. She smiled and called out, "Hi, long time no see, Tenten!"
The chubby, cute little girl, Tenten, saw Izumi and immediately ran forward, happily shouting, "Izumi-jie jie, you're here, long time no see!"
Izumi half-knelt. She rubbed her cute cheeks with both hands and said, "I've cultivated some very powerful Medical Ninjutsu!"
Tenten said with some disappointment, "Huh? Medical Ninjutsu? What's so powerful about Medical Ninjutsu?"
"Don't underestimate Medical Ninjutsu, Tenten!" Tenten's father patted his daughter's head and then said, "You're here to pick up your custom-made weapon, right?"
Izumi released Tenten and nodded, "That's right."
Hearing about the weapon, Tenten also wondered what kind of Ninja tool Uchiha Izumi would use.
Izumi followed Tenten's father into the house.
Tenten's father took out a long weapon wrapped in cloth and said with a smile, "Your demands were too high. I specially entrusted a friend from the Land of Artisans to customize this for you. I owe him a huge favor!"
Tenten asked, "Is that a spear?"
"No," Izumi unwrapped the cloth and saw a long, pitch-black brush, fully two meters long, getting thicker from the end to the brush tip.
"Ah? It's just a brush!" Tenten asked in surprise, "Can this be a weapon?"
"Of course." Izumi swung it a few times and said happily, "This is a great item, it feels so natural in my hand!"
"That's right, the materials alone cost a fortune!"
Izumi clapped her hands and said with a smile, "Don't worry, I'll pay for it, and I can fulfill what I promised you right now."
"Ah? Really?" Tenten's father was very surprised, but then asked with some sadness, "But this is a surgery that even the elites of Konoha's Medical Department couldn't complete!"
Izumi bit her finger, smiled, and slammed her hand on the ground, "Ninjutsu, Summoning Technique!"
"Boom!" A Katsuyu the size of an arm appeared under Izumi's palm.
"Ah? This, this is..." Tenten's father looked at the Katsuyu in shock and said, "Lady Tsunade's..."
Izumi rubbed her nose and said, "See, I don't need to lie to you, right? You're my dad's friend, and we're both branch families of the Senju Clan, there's no need at all!"
Tenten's father grabbed Izumi's arm and said excitedly, "In that case, you can definitely do it! Izumi, please help my wife!"
Izumi smiled and said, "No problem!"
Tenten's father led Izumi to a room.
Inside, lay a woman in a wheelchair, who was Tenten's mother.
Izumi looked at her, knowing she was an ordinary person with a spinal problem, lacking strong regenerative abilities. And this surgery was quite tricky; even Tsunade wouldn't dare say she could definitely do it, but Izumi herself could.
After Tenten's father told his wife about this, her dim eyes suddenly lit up, looking at Izumi full of hope.
Tenten's father asked, "Do we need to go to the Hospital for the surgery?"
Izumi shook her head and said, "No need. I have a Katsuyu, and I have medical equipment. There's no need to worry at all."
"Good!" After all, she was a highly-skilled disciple of Tsunade, so there shouldn't be any problems.
The surgery began. Countless fine threads of Chakra appeared in Izumi's hand. These threads continuously operated within Tenten's mother's lumbar spine. Izumi's other hand treated and paused, repeating back and forth, repairing her cells.
Tenten and her father watched this scene nervously from the side. They saw Izumi's focused expression and dared not speak.
Finally, Izumi let out a sigh of relief, then wiped her forehead and said, "It's done."
She said to the Katsuyu, "Thank you, Katsuyu-sama. Just let her wake up!"
The Katsuyu made a sharp sound and said, "It's nothing, but your Medical Ninjutsu is getting better and better!"
It awakened Tenten's mother, and then disappeared.
Izumi instructed Tenten's father, "Let her rest for a while, and then she can try to exercise."
Tenten's father asked excitedly, "Can she really?"
He saw that even the Katsuyu said so, so of course, he trusted the Katsuyu. This was Lady Tsunade's Summoning Beast.
Izumi nodded, "Of course."
His wife said in surprise, "It really feels like it!"
Tenten's father heard this and immediately said excitedly, "Thank you! I'll give you whatever amount of money you want. In the future, if you need any weapons, just come. I'll give you whatever I have!"
"No need, for me, it was just a bit of effort."
In the end, Izumi not only didn't pay for the weapon but also received a large sum of money from Tenten's father, which Izumi "reluctantly" accepted.
Before leaving, because the amount of money given was truly too much, making her feel a bit awkward, Izumi gave Tenten a few of the special talismans she had made.
Tenten was overjoyed.
On the way home, Izumi touched the money in her backpack and happily said, "No wonder there were so many pharmacies everywhere in my previous life, and those who ran Hospitals made so much money. Medical care really makes money fast."
Izumi then thought about how the doctors who worked hard on surgeries didn't earn much more money, and she couldn't help but sigh, "Capital is truly powerful."
She thought about how the high-ranking Hospital officials caught for corruption even tried to persuade them to arrest fewer people, otherwise, there wouldn't be any good doctors left. Who would believe that? Were they really all promoted based on their abilities? The doctors who worked tirelessly like oxen and horses, with pitifully few holidays, were the truly capable ones.
No longer thinking so much, Izumi happily returned home.
During this time, Tenten's father also introduced Izumi to a few private jobs, all similar to his wife's situation: unable to move, either a broken arm, or spinal, thigh, and other bone injuries, as well as some old chronic illnesses.
The most troublesome were conditions caused by poison. Although the poison could be removed, over time, the poison in their bodies had already damaged them considerably, making it very difficult for Izumi to treat, only able to gradually condition them.
Izumi also used Traditional Chinese Medicine theories from her previous life, and unexpectedly, they were very effective here. Izumi thought that this world incorporated many Chinese and foreign cultures, and she felt relieved.
The money Izumi earned during this period was far more than what she earned as a Ninja for several years, which made her want to become a Medical Ninja.
"If there weren't those crises, maybe I really could become a Medical Ninja."
Izumi thought of the future crises and immediately dismissed those thoughts.
When the holiday ended, Izumi also began various missions with her new teammates.
Her new teammates were one Jonin and two Chunin. Everyone had already met and quickly integrated.
