Konoha Camp, inside the camp where the wounded are housed.

The cries of pain one after another were endless, making the whole camp seem extremely noisy. People came and went, some of the wounded who had just been brought in, some who helped the wounded out, and some who came in to visit, and the crowded, chaotic appearance made it impossible for Hanzou to fully concentrate on remembering every step of the ninja who guided the medical ninjutsu and the analysis of the symptoms.

Since Yunyin's AB combination appeared, the pressure on this side of the front has been very great. Before, it was a little better when the two sides had a large-scale melee, and the commander Zilai could also rely on his rich experience to contain the Yunyin ninja named Ai, and the Eight Tails could also use the formation of the Four Purple Flame Formation to cooperate and contain it, but before the next big war, due to repairs, the two sides changed the large-force combat to a squad to lurk, conduct military intelligence spying, and disrupt the rear, and the boss must not move lightly, and there are almost no people on Konoha who can balance the AB combination. Therefore, as the failure rate of ninja missions increased and the number of wounded continued to increase, Konoha had to shrink his forces and reduce the attendance rate of the squad, and only those who were equipped with sensing ninjas or who had Hyuga in the team could carry out the mission, that is, the team must have long-range detection capabilities to avoid the combination of the enemy.

And it was in this situation of the surge in the pressure of treatment that Hanzo came to the camp to treat the wounded and learned to help with the medical ninja. Because there are too many injured people, the task of treating medical ninjas is very serious, and there is no extra time to teach the course, so a lot of changes have been made in the teaching method, taking the students with them, and assigning several students to each experienced medical ninja, so that in the treatment process, when they encounter any problems, they will teach relevant knowledge while treating. This brings some problems, because each ninja encounters different problems, the corresponding daily income of each student is also different, if there is something missing, then it is more likely to be stuck in a thing when reviewing at night, resulting in a weak foundation.

Luckily, Hanzo had already passed the first phase before they could make changes to the way they were taught. Of course, the selection is very strict, and the requirements will not be lowered due to lack of manpower. This also caused the number of people who entered the training class to drop from more than fifty to about twenty, which was more than half, and there were fewer people, and the pressure of substitute teaching for medical ninjas also came down, but it also made Hanzo and them not even have anyone to communicate with.

In order to cope with this situation, Hanzo had to cast the shadow clone, and the main body and the shadow clone cooperated with each other, and while one helped, the other wrote down the knowledge. It is also in this hectic atmosphere that everyone ignores the process, and Hanzo sometimes uses shadow clones to operate this way of increasing proficiency. In addition, Hanzo had already mastered the chakra scalpel, so he was able to keep up with the pace of learning well, and gradually helped the instructor, and the person who taught the relevant knowledge had a good impression of Hanzo, and he was more enthusiastic about teaching, even if he was tired, he was willing to answer Hanzo's doubts. This can't help but make Hanzo sigh, thinking that a good student in the eyes of a teacher like Xueba can be popular anywhere.

Busy like this, addicted to learning and unable to extricate himself, Hanzo's basic knowledge of medical ninjutsu is gradually solidified, and he is getting closer and closer to becoming a real medical ninja. Although Fukuda told him not to distract himself too much, if he continues like this, his combat strength will not be greatly improved. For the medical ninja that Fukuda repeatedly reminded as far as Konoha is concerned, only Tsunade-sama has extremely high combat effectiveness, and none of the others can fight, Hanzo knows in his heart, and even for Hanzo, Fukuda vaguely hopes that he will give up this path, but he is also prevaricated by Hanzo pretending to be confused.

That night, Hanzo thought about his own development path for a while, but he was thinking about how to go after becoming a medical ninja. As for giving up the training of a medical ninja or failing to pass the training, Hanzo didn't even think about it, if he really did this, what Orochimaru left in his body would definitely kill him. As for telling Fukuda that there was something in his body, Hanzo didn't think Fukuda could cover it, and maybe he would be implicated. Moreover, Hanzo was reluctant to cut off contact with Orochimaru in his heart, because whether it was the cells between the planning pillars or the high-level ninjutsu in the Konoha Forbidden Book in the future, it would be much easier to get these through Orochimaru than to go by himself. Although this is a fire in the fire, it is definitely one of the few ways to increase Hanzo's own ceiling, and it is also the fastest way relatively speaking.

Hanzo thought about it, since he has the attributes of water and thunder, there is nothing that Thunder Ninjutsu Konoha is good at and is well-known, and even if he has, he will not teach you for no reason, and he will not always meet good people like Fukuda and Oki, after becoming a medical ninja, he will definitely have to develop into a water ninja, unless his cultivation encounters a bottleneck and he is considering Lei Dun. The development route of the Water Escape Ninja can completely follow the path of the second generation Hokage, after all, the development of the Water Escape between the doors is already very mature, there are attacks, defenses, and illusions are involved.

In Hanzo's mind, Orochimaru has been sealed by ghouls, and he will definitely have the opportunity to obtain all the ninjutsu in the door, as long as he reflects his value, he should be able to get some benefits, and Yakushi Dou can become one of the big bosses in the Four Wars period, completely by virtue of Orochimaru's research results for many years.

"Hanzo, scrape the necrotic flesh of this ninja, do some preliminary treatment, I'll get this side done soon, pay attention to the blood vessels, no problem, right?"

"No problem."

Hanzo, who received the instructions, skillfully dealt with the injured accordingly, and when the other party showed distrust when he saw his young age, he smiled at the patient like a real doctor and gave him a reassuring look.

"Take it easy, don't be nervous, the adult won't let me do the difficult operation, he can let me do this part of the work because he knows my ability, please trust me."

"Ah, I'm sorry! I just want to get better quickly, after all, we're going to fight back later, and I'll be able to go to the battlefield sooner and kill the enemy. ”

"Really? Aren't we strategically shrinking now, do we have a way to restrain the opponent's speed ninjas? Hanzo asked curiously.

"Of course! It is said that we are going to transfer a powerful young ninja from another front, and he is also a very fast person, it seems to be called Bo Feng Shui Gate or something. If he can defeat the other party's bastard called Ai, he will be my idol in the future. ”

"Bo Feng Shuimen, it seems that the golden flash is about to appear, I don't know if I have a chance to see it." Hanzo thought so.

"Ah, it hurts! Please, don't get distracted. ”

"I'm sorry, I'm really sorry."
