The next day, after they finished breakfast, Haru was about to leave when suddenly Tsunade grabbed him by his collar and said, "Haru, from now on, make some time. I will be your medical teacher." Haru looked at Tsunade, then at Mito, who was smiling at him. Seeing Mito nod her head, Haru understood that she was the one who recommended him to Tsunade.

Haru nodded at Tsunade and expressed his gratitude, apologizing for any inconvenience he might cause her. Tsunade chuckled and flashed her mischievous grin, cracking her fingers as she assured him, "No need to worry. You won't be a bother at all. In fact, I'm excited to teach you. I promise that by the time I'm done with you, you'll be a very skilled medical ninja at the very least."

Seeing her like this, Haru was curious about what got on her nerves, but he decided to keep silent and just promised to be on time. Being on Tsunade's bad side when she was angry was a very scary thing to do, and he wasn't interested in being her punching bag.

And just like that, another class was added to Haru's already full schedule. After getting Mito's permission, Haru decided to use a clone in his place at school so that he could have time to study with Tsunade. Unlike Nawaki, Haru was always calm in class, so even if he didn't participate in any physical activities, they wouldn't suspect him of using a clone. Since he already had two clones, this new one would be solely for the time he spent studying with Tsunade. If he were to create three clones at once, the fatigue in his body and the resulting chakra depletion would not be enough for him to practice medical ninjutsu.

Haru arrived at the clan on time for class and found Tsunade already there, waiting for him. Although he was sure he wasn't late, he still apologized for arriving after her. Today, Tsunade's mood wasn't good, and Haru made sure not to further irritate her.

Noticing Haru, Tsunade came out of her daze and started the class by explaining the basics to him. He listened to her very carefully until she finished before saying, "Tsunade-nee, I already knew those topics. I've been reading a lot of books in the past. I think we can go straight to practice already."

Unlike his other teachers, Haru didn't need to hide his edge around Tsunade as she was family. Showing his talent around her wouldn't bring any negative consequences to him, unlike the rest who were outsiders. Even though they all knew Haru was talented, they didn't know how much exactly. In their eyes, Haru was a very intelligent and hard-working child, nothing more. And this was what Haru wanted to show them. In the ninja world, showing talent would attract a lot of attention and responsibilities no matter how young you are. They would throw you into battle right away and use you as a political pawn until they had drained you dry. Seeing how Kakashi and Itachi were treated was enough for him not to flaunt his talent around. He didn't want to have psychological problems by the time he was a teenager.

For most occupations, you don't just need talent; you need mental strength to succeed, especially being a shinobi. You need to be tough mentally if you want to survive in such a world.

Hearing what Haru said, Tsunade was silent for a moment but decided to believe in him. Even though she didn't study under Mito, she knew how strict her grandmother could be. Since Haru was already her disciple, he shouldn't talk without being sure. So she took him to the small library in the house and told him to sit while she took a piece of paper and started writing some questions on it. Even though she believed him, she still needed to know how much knowledge he had and find any blind spots to help him improve.

Unlike ordinary ninjas, medical ninjas need to have a vast amount of knowledge about a wide range of topics to perform even simple healing ninjutsu. That's why many ninjas don't dabble in medical ninjutsu, as the vast amount of knowledge required takes a lot of time to study. Therefore, medical ninjutsu is a highly specialized area within the ninja world. Most medical ninjas are not as combat-focused as regular ninjas. There are some exceptions, but those are usually genius ninjas and not the norm.

Haru waited calmly for Tsunade to finish before taking the paper and starting to answer the questions one by one. They weren't hard, as they were the most basic ones, but Haru still answered them very carefully. As a doctor, the lives of your patients are in your hands, and even for the most basic procedures, you can't take them for granted. Any lapse of judgment can result in the loss of life. This was Haru's attitude from his previous life, and it carried over into his current one.

After Haru finished, he gave the paper to Tsunade and patiently waited for her to finish reading. She then said, "Well, I suppose you do know about medicine. I wasn't aware of this before, so I need to modify my plan. Starting tomorrow, we'll begin testing you to assess your knowledge. Once I know the extent of your understanding, we can determine if you're ready to begin training."

Hearing this, Haru agreed with Tsunade's approach and took some books that might interest him before heading back and leaving her to start writing some tests for him.

In the next couple of days, Haru's class with Tsunade consisted of him taking a lot of tests. At first, they were all very easy and basic. But as Tsunade saw that he answered them with ease, they gradually got harder and harder. To be honest, Haru already liked his class with Tsunade as she was a very good teacher and would try to give him new information about the topics, even if he already knew them. Although he had been reading non-stop for the past couple of months, there were still new things he could learn from Tsunade every day.

And he wasn't the only one having fun; Tsunade was too, even though she was the one teaching Haru. Conversing with someone who had such a vast knowledge reserve brought her a lot of enjoyment, as she needed to find interesting and unique answers to teach him anything new.

In just one week, Tsunade had already figured out Haru's advantage - he was a bookworm. He had read a huge amount of knowledge about many different topics from different sources and had a very deep foundation. However, all he knew was what was written in books. He didn't have any personal experience, so if you asked him about something that wasn't covered in books, he wouldn't know. But that was to be expected, as he was just a newbie - a very knowledgeable newbie. But that alone was already extremely remarkable, as your reserve of knowledge can determine how good of a medical ninja you can be. In Haru's case, Tsunade was sure that he would be an excellent one.

Today, they finally ended the tests and moved on to another crucial topic for medical ninjas: chakra control. Tsunade pointed out, "Well, since you're already knowledgeable, I assume you understand the significance of chakra control for medical ninjas. Many techniques require a high level of control, particularly when performed on other ninjas. Sometimes, even when they're unconscious, their chakra can surge, and poor chakra control can have disastrous consequences. So today, we'll discuss this topic. Although I suppose you already know how to seal so your control wouldn't be bad, just to be sure, you already knew how to walk up a tree and walk on water?" Haru nodded his head, indicating his proficiency in chakra control. Even before training with Matsuyaki, his chakra control was already excellent, as sealing necessitated delicate control, particularly when writing seals.

Then, Tsunade gave him a big grin, and Haru started to feel uneasy. She then led him to the training ground and asked, "Do you know how to use Chakra Threads?" Haru nodded. Chakra Thread is not a very difficult technique when you have good chakra control, at least the simple version. If you want to use it in puppets, you will need very high chakra control, and in most villages, except for the Village Hidden in the Sand, puppetry is not a very mature art. But, a simple version of Chakra Threads is mostly available.

Upon hearing this, Tsunade smiled and said, "Well then, today we will start testing your chakra control. Since you already know the basic exercises, why don't we try something interesting?" She then pulled out a small pouch and said, "This is filled with pebbles. Now, I will throw them at you, and you need to move them using only chakra threads. You can't use your body at all."

This exercise is particularly effective for improving chakra control, as Tsunade's ability to throw the pebbles at varying speeds and weights from different angles requires Haru to stay alert and maintain a high level of focus. As he uses his chakra threads to move the pebbles and protect his body, he will need to have excellent chakra control in order to achieve the precision and accuracy required for success. Any misstep could lead to a pebble striking him, potentially causing injury. Thus, this exercise not only tests Haru's abilities but also helps him to improve his concentration and develop a greater degree of control over his chakra.

Seeing that Haru understood what she meant, she put on a huge smile and became very excited for the fun they were about to have.

After a while, Haru stood there and tried to cheer up Tsunade, who was very frustrated and angry. He said, "Tsunade-nee, don't be sad. This test is really good. It's just that in sealing, you really need very good control. You know Grandma is very strict. It's my fault. Your training is really good."

In the end, Tsunade didn't have any of the fun she had anticipated, as Haru aced her test with flying colors and extinguished her excitement immediately. In all fairness, this test was really good and fun, at least for Tsunade. Even if it was a bit challenging, it would train you to have a lot of chakra control.

Seeing that Tsunade was still upset, Haru decided to offer up Nawaki as a sacrifice. Having an upset Tsunade on his back would be very difficult, so he said, "Well, how about we show this exercise to Nawaki? From what I know, his chakra control is very average. I think he would be very jealous if you trained me alone. Even if he can't become a medical ninja, having better control is still very necessary. As his elder sister, you should really help him train his shortcomings."

Upon hearing this, Tsunade's ears perked up, and the smile returned to her face. She then stood up excitedly and said, "What you said really makes sense, Haru. That brat really needs training in this aspect, and who could be better than me, his own sister, to teach him? Let's go. He should be back from school."

Seeing Tsunade's excited look, Haru prayed in his heart for Nawaki's well-being, and then brainwashed himself. "Some people really need some pain to understand better," he put Nawaki in this category, convincing himself of this. He nodded seriously at Tsunade and said, "You are a really responsible sister, Tsunade-nee. Nawaki is very lucky to have you."

Tsunade listened to his sweet talk, and her mood improved tremendously. From now on, she decided to treat this brat a little better. Having someone who knew how amazing she is is really a good feeling.
