Orochimaru and Tsunade were led by a medical ninja to a large, clean, and empty classroom. The walls and ceilings were snow-white, with lower ends of the walls painted dark green, and large red cross and wood leaf signs adorned the walls. Small baskets filled with disinfectant spray were spaced along the wall, and the floor was covered with square white stones, creating an atmosphere of solemnity and silence.
Orochimaru was excited by the scent of medicine masked by the disinfectant and grinned with anticipation. He was starting to enjoy the ambiance of the medical class!
As transfer students, Orochimaru and Tsunade occupied the last seats in the classroom. On the stage, a male medical ninja demonstrated with a wooden doll covered with diagrams of human anatomy.
The teacher spoke incessantly, while thirty or forty students in white coats below listened with great interest, jotting down notes diligently.
At that moment, Tsunade immersed herself in the role of a scholar, meticulously recording every essential point.
"The main idea behind medical ninjutsu is to use one's medical chakra to accelerate the division of cells in the injured area, promoting rapid wound healing. However, the effectiveness and chakra consumption vary depending on the technique used," the teacher explained.
Orochimaru's powerful soul force allowed him to quickly memorize and comprehend every word. It was a piece of cake for him, especially since his enhanced spiritual power enabled him to recall medical knowledge from his previous life.
Back in his own time, Orochimaru had access to various medical materials, though he only skimmed through them back then. Now, his potent spirit brought back all that knowledge.
He noticed that medical treatment in the Naruto world mostly relied on chakra and herbal medicine, lacking the emphasis on nursing and surgery.
Orochimaru couldn't help but smirk. In his previous life, traditional Chinese medicine was the oldest medical system globally, especially in the field of surgery. It had even developed anesthetics nearly two thousand years ago and performed craniotomies.
However, Western medicine surged ahead with the "Anatomy Act," providing access to numerous cadavers for research and experimentation. From that point on, Western medicine advanced rapidly.
Orochimaru knew that real progress required more than just theoretical knowledge; it demanded practical experience. Uncle Snake (referring to Orochimaru) was, indeed, an outstanding medical ninja.
"Why are you in daze for? Pay attention to the lecture!" Tsunade scolded Orochimaru playfully with a tap on his head using her pen.
At that moment, Tsunade was dressed in a white short-sleeved navel-baring T-shirt and a dark red short skirt, giving her a nurse-like appearance.
"Tsunade, do you know who excels in understanding the human body the most?" Orochimaru inquired with a mischievous grin.
"Isn't it medical ninjas who treat patients?" Tsunade replied, a little puzzled.
"No, I think it's the ANBU who gather intelligence, handle corpses, and interrogate prisoners!" Orochimaru quipped, appearing like a strange and whimsical doctor with his dark hair and purple eyeshadow.
Tsunade rolled her eyes in exasperation.
From then on, Orochimaru and Tsunade embraced their new routine, shuttling between home and the hospital. Orochimaru found joy in every moment and felt fulfilled in his work.
With his remarkable learning ability, Orochimaru quickly mastered medical skills, just like Tsunade. Both of them showcased their exceptional talents as medical ninjas, leaving countless onlookers in awe.
As the news of Orochimaru's excellence spread, many villagers requested his medical services, eager to witness the so-called "genius" in action.
Little did they know that Orochimaru's hard work behind the scenes was the true key to his success. He spent time in the hospital's mortuary and corpse storage area, his main base of operations.
Though frowned upon by civilians, Orochimaru's use of autopsy was tacitly approved by the higher-ups. Many medical ninjas knew about it but were still apprehensive in Orochimaru's presence.
During this time, Orochimaru collected numerous ninja blood and tissue samples, a task challenging outside the hospital but easily achievable within its walls.
With the perfect "conditions for committing crimes," Orochimaru made modifications to his body. His broken limbs now regenerated twice as fast, allowing him to extend his body like a snake if he desired.
Yet, there was still one goal he couldn't achieve just yet—growing back his head after being cut off. It required a complete transformation of his body and spreading the power of his soul throughout, something Orochimaru couldn't accomplish with his current abilities.
With some medical knowledge from his previous life, Orochimaru developed several medicines and treatments, which left even the talented Tsunade impressed.
As Orochimaru's accomplishments cooled off the initial hype, he became a forgotten prodigy in the ninja world.
However, there were still those who didn't forget the shock Orochimaru had given them, like Danzo, who couldn't dismiss the memory of his strength during his test. He knew Orochimaru was more than just a skilled healer.
Meanwhile, Jiraiya, under Sarutobi's guidance, grew stronger and decided to embark on higher-level training, leaving the village with a huge scroll on his back, seeking further improvement.
