Steel Hand was lying lazily on the bed, holding a book in his hand, looking at it very carefully, when there was a knock on the door.

"Come in."

As soon as Hippo Hanyu put his head in, he immediately retracted and closed the door gently. Is there any mistake, whether the steel hand is a woman or not! How can you let someone into your room casually, especially if you are still a mature man (at least psychologically). Although it was only a glance, he had already seen the steel hand's plump chest half exposed, and he was so frightened that he retreated again.

Alas! Looking back, I have been a boy chicken for seven years, and it seems that I will continue to do it for a period of time, but I am really not a good man and a woman, and in the face of the temptation of mature women, the resistance is very low, especially a plump mature woman like Steel Hand, and it is the object of countless men's sexual fantasies, Hippo Hanyu thought.

Steel Hand didn't have so many ideas, but when she saw the strange performance of Hippo Hanyu, she realized that she was wearing pajamas. While changing clothes, Steel Hand couldn't help but think of Hippo Hanyu's expression just now, it's really cute!

Han Yu, the hippo who had been waiting outside the door for a long time, couldn't help but think about it, but he forgot that Steel Hand was different from other women he had contact with in his previous life, he would not spend a lot of time on makeup and clothes, and soon opened the door.

"Ahem-,ahem-" Steel Hand knew at a glance that Hippo Hanyu must be thinking about some dirty things, and he didn't even react when she stood in front of him, if Steel Hand gave him a punch at this time, it is estimated that he would not be able to dodge.

"Ahh Steelhand-sama. Hippo Hanyu's face was flushed, he was obscene, but he was hit by the object of obscenity, even if he was as thick-skinned as him, he couldn't help but be embarrassed.

"Come in and sit!" As if he didn't see the embarrassment on his face, Steelhand opened the door and let her in.

"I thought you weren't coming." The steel hand poured a cup of tea and handed it to Hanyu the hippo.

"How so? I'm really interested in medical ninjutsu, and you may not believe it, but I really hate killing, and watching life pass in front of me, I get frustrated by the fragility of life. Moreover, I want to use my medical skills to protect the people I care about and those who care about me. ”

Maybe it was the last sentence that touched the string called memory in the heart of the steel hand, maybe it was his thoughts that resonated with the steel hand, at that moment, the steel hand fell into contemplation, and Hippo Hanyu suddenly felt that such a steel hand was very beautiful, not only in appearance, but also in a kind of spiritual beauty.

Steel Hand is pitiful, although she was born in the House of Hokage, but she has never had the opportunity to taste the taste of her relatives since she was a child, and she can't do anything about it when she sees the war take her dearest and loved people away from her, in Konoha, she should be the one who hates war the most!

She is actually fragile because of her strong appearance, otherwise she would not have suffered from hemophobia because of psychological shadows. Always uses violence to cover up her innermost thoughts and doesn't let others get close, so she should be lonely! At this moment, Hippo Hanyu also found his own shadow from the body of the steel hand.

"Why do you say people die?" Steel Hand asked blankly.

"For a better life. Death is not the end, but the beginning of a new cycle of reincarnation. Hippo Hanyu didn't know why he answered, as if he was annotating himself.

The relatively silent two were woken up by the sound of the night bell, and Hippo Hanyu put down the tea that had already been cold, stood up and said, "Sorry, I'm disturbed." It's not early, so get some rest! ”

"Wait." Steel Hand remembered that he originally had something to say to Hippo Hanyu, but he didn't expect it to end up like this, "These are the notes I put together before, you can refer to them." There are also materials mentioned above that you need to learn to learn medical ninjutsu, you can go to the reference room and borrow them. ”

"Thank you! Good night, then, Lord Steelhand. "Hippo Hanyu wants to retire early.

Fortunately, the steel hand didn't leave him alone, and Hanyu, the hippo who returned to his room, shook his head, trying to throw out all those distracting thoughts.

For the next month, Hippo Hanyu carried the information every day, and although there were two shadow clones to help, it still took him a month to learn the information as high as a mountain. But this degree is a miracle in the eyes of others, although the status of the medical ninja is not high, but it does not mean that the medical ninjutsu is not remarkable, in fact, in this era of constant war, the medical ninja is very popular.

Although Hippo Hanyu had a classmate who was a doctor in his last life, he himself was an absolute idiot for medical skills, but even if he was an idiot, he still knew the basic professional requirements of the doctor industry. Medical ninjutsu is also a medical technique, and medical ninjas are a special group of doctors, and if a doctor makes a wrong diagnosis, it is equivalent to murdering a life.

Hippo Hanyu is thick-skinned, but he also has a great advantage, that is, a sense of responsibility, as a doctor, he must be responsible for patients. Therefore, Hippo Hanyu not only memorized all the existing medical skills, but also worked hard to understand the meaning of every medical term. After having a certain amount of theoretical knowledge, Hippo Hanyu began to learn on the spot.

Undoubtedly, Hippo Hanyu is a very good student, just as he promised before, he did not always go to the steel hand or the pharmacist Tianshan them, but observed by himself, wrote down every case and diagnostic plan he saw, and returned to the room at night to study, analyze, and sort out behind closed doors.

Then in a laboratory where no one is around, all kinds of experiments are done with those injured animals. He already has all the medical ethics and skills that a doctor needs, and the only thing he lacks is experience. Hanyu the hippo even experimented with different ninjutsu to injure animals and then treat them to find the subtle differences. Just like there is no master key in the world, Hippo Hanyu does not believe in any omnipotent medical ninjutsu, he firmly believes that because the nature of chakra is different, the damage caused is not the same, and the corresponding treatment methods are also different. Among them, how to grasp the degree of "quality" and "quantity" is very important.

For the great research of Hippo Hanyu, the animals of the Death Forest have worked hard, I really don't know why Hippo Hanyu likes to abuse the animals of the Death Forest so much, is it because they are easy to bully.

After animal experiments, Hippo Hanyu set his sights on people, and such good luck befell Ryumeng and Sakikawa, who were captured by Hippo Hanyu, let's pray for both of them! Amen!

The strange thing is that since the incident that night, Steelhand has never looked for Hippo Hanyu, and Hippo Hanyu has not looked for her, even if the two met in the hospital, they just politely said hello, and then left quickly.

After learning the knowledge of the medical ninjutsu system of this world, Hippo Hanyu began to learn ordinary medical knowledge, and it took him half a year to learn these things. He, Hippo Hanyu has completely integrated into the role of a doctor, and no one would have thought that this young man who holds notes and books all day long, records behind the backs of others, and makes various preparations and antidote pills in the laboratory is the famous Konoha gray wolf who kills like Konoha White Fang.

In the backyard of Konoha Hospital, there is a newly built shed, and Hippo Hanyu is planting some exotic flowers and plants in it at the moment, which are actually some precious herbs that he went out to find and try to cultivate.

"Zheng Taijun-" Medicine Master Tianshan looked at Han Yu, a hippo who had no time to pay attention to it for a long time, and really admired his ruthlessness.

"What's the matter?" Hippo Hanyu didn't look back and asked.

"There's a new poison, Steelhand, please come over."

"Okay, you go first, I'll be here in a moment."

After the pharmacist Tianshan left, Hippo Hanyu left a shadow clone and put the real medicine shed under the enchantment before leaving with confidence.

The time is May 18, the forty-first year of Konoha, and Hippo Hanyu has been in the hospital for nearly two years, in the past two years, in addition to going home to see his mother from time to time, occasionally drinking a glass of wine with Jiraiya, and meeting his ninjutsu teacher Qimu Shuomao, basically he has never left the hospital, even if he left, it was to go out to find medicinal materials.

Because of his low profile, some of the opinions of the Konoha high-level about him have gradually faded over time, and it seems that there is no such person as the Konoha gray wolf in the world. However, in Konoha Hospital, almost every medical ninja and ordinary medical staff knew him - Yoshino Shota, and he won the title of ghost doctor in two years.

A sentence from Hippo Hanyu has been widely known to medical personnel: "The treatment of ninjutsu is broad and profound, and there is still a lot of space for us to dig and explore." ”

Although he was not a member of the medical class, he had earned the respect of all the medical staff in the medical class. Hippo Hanyu began on-site treatment in January of the 41st year of Konoha and is said to have been jointly approved by Tsukade and Yakushi Tenzen. And the talent shown by Hippo Hanyu in medical forbearance is not as good as that of the steel hand and the pharmacist Tianshan.

So later, Steelhand and Yakushi Tianshan would discuss more troublesome problems with him, and Hippo Hanyu learned more things through the process of communicating with the two.
