Marvel: Trading with Worlds

"The study of the Curse Seal to strengthen the body? It's indeed a good choice for training subordinates, but not right now. The affairs of the village are too busy. Even if I separate Chakra and use Shadow Clones, I can't do it. If you can bring Tsunade here... Fortunately, with her ability, it should be very fast."

Orochimaru didn't think much of it when he heard Kain's words. He didn't do it on purpose. Many Jōnin in the village had already canceled their missions, and ninjas like him might soon be sent to the front lines again. Even if he were interested now, he couldn't spare the time for research.

Kain shook his head and said to Orochimaru on the tablet: "Tsunade is not like you. She can't tolerate many things. Since you don't have time, let's talk about it later. But don't push the interview about the newspaper, or I will let the newspaper print their minds."

After speaking, he ended the call. Though he was a little regretful—while war could be a good time to make a fortune, it also delayed many other things. He definitely didn't want to seek Tsunade's help, unless she was personally aligned with him. Otherwise, the news would leak out soon.

Besides Tsunade, there was Yakushi Nono. Her medical ninjutsu was excellent. Even without the status of Tsunade's student, Yakushi Nono's medical skills were among the best in Konoha Hospital. 

But she wasn't involved in human experiments, and her medical ninjutsu was still a work in progress.

At present, she didn't meet Kain's required standards, and she might not be qualified until a few years later.

"By the way, there are two people who are very suitable: Shinno and Hiruko."

Kain suddenly thought of these two. They were excellent in body research—one had developed physical activation and regeneration, and the other could integrate bloodline limits. 

If they could be found and controlled with the Imperius Curse, Kain could have two human researchers at his disposal.

It was just that Kain didn't know if they could still conduct research after the Imperius Curse was used on them.

"Find their traces first, and then I will personally 'convince' them."

Now, Shinno and Hiruko should be just Jōnin, with Shinno's strength being even weaker. Without physical activation and regeneration, he was a medical ninja. The former should be easy to find, as he was often used as a ninja doctor in the ninja world. The latter would take a while.

"Shadow Clone Technique."

After Kain created a Shadow Clone, he sent it to leave Konoha and go to the underground gold exchange office to issue tasks. He had Apparition and could ignore Konoha's enchantment to travel anywhere he had clearly memorized in the ninja world.

However, the farther away he traveled, the more mana would be consumed by Apparition. But with Kain's strong magical power, even traveling from the Cloud Shinobi Village to the Sand Shinobi Village was no problem. As long as there was news, Kain could immediately 'invite' Shinno and Hiruko back.

Under Tsunade's medical reform, the new medical course has been established as a regular subject in the ninja school curriculum. Starting from the second grade, all students must participate, but only in the fourth grade will an assessment be made to determine who is suitable to become a medical ninja.

Sarutobi Hiruzen and the other Konoha executives had no objections to Tsunade's proposal. They didn't need to spend more money and could train more medical ninjas for Konoha, so they had no reason to object. 

It was simply one more class for the students of the ninja school, but playing less meant a better chance of surviving on the battlefield. This was also for the benefit of the students.

Before the selection and examination of medical ninjas, the students at ninja school learn a series of first aid techniques, such as bandaging, suturing, diagnosing internal injuries, as well as identifying herbs and learning basic healing techniques.

If they can learn the healing technique, it means the student is very talented in medical ninjutsu.

Under normal circumstances, second-year students at the ninja school can learn the healing technique within a year and potentially become medical ninjas in the future. However, before they can learn the healing technique, they must first improve their Chakra control ability to an extremely high level.

As a result, very few students learn the healing technique in the first year. It's usually only in the second or third year that someone can successfully perform it.

Students like Shizune and Nohara Rin were able to perform the healing technique after only half a year of learning, which means they will definitely become medical ninjas in the future.

"Before class ends, I want to remind all students not to take the medical class lightly. The grades in this class will be linked to your graduation scores. If you do poorly in the exam, it will significantly impact your placement after the exam," Yakushi Nono said to the students with a flat expression. 

They did not realize the importance of medical ninjutsu and first aid on the battlefield, particularly in terms of squad configuration.

If they don't perform well, they will be assigned to what's called a 'cannon fodder' squad.

It's a bit of an exaggeration to call it cannon fodder, but it's certain that they won't be taken seriously by the upper echelon or even the frontline command. When the time comes, depending on the team's composition, they might be sent on 'decoy' missions.

"Teacher Nono."

After Yakushi Nono left the classroom, Nohara Rin hurriedly chased after her. Uchiha Obito stretched out his hand to stop her, but before he could speak, Nohara Rin had already run out of the classroom. 

He wanted to ask Rin something, but this time, it wasn't possible.

"Nohara-san, it's you. What's the matter?" Yakushi Nono smiled kindly. Although she was only sixteen years old, her position as a teacher and her caring, older-sister demeanor made her seem more mature than her age.
