Naruto: The Medical Ninja

Chapter 186: Chapter 185: Memories

The next day in the academy, he kept on training his earth affinity under the desk. He always used parallel thinking to train this way without losing focus on what is being taught at the front.

After the class, Saya, Takeshi Yamamoto, and Fumi Suzuki joined him. Takeshi told him, ”We are done with the task you gave us. We all can now walk on water.”

Ryu congratulated them and said, ”Well done.”

Ryu thought, ’Now they won’t have a hard time learning ninjutsu.’

Takeshi replied, ”Thank you; walking on the water is cool; I can’t get enough of it.”

Ryu tells them, ”It definitely is cool, but water walking had much deeper purposes than just being cool. Now you all have proper chakra control to start training for ninjutsu.”

Hearing ninjutsu, both Fumi’s and Takeshi’s eyes sparkled. Both were from civilian backgrounds without any history or legacy of ninjutsu.

Ryu said, ”But first we need to test for your chakra natures.”

Fumi said, ”Finally. I thought you wouldn’t teach us anymore since you have not taught us anything for the past few weeks.”

Ryu said, ”I was too busy. You know I am also in a medical apprentice course.”

Takashi said, ”That is why we didn’t disturb you and trained on our own.”

Ryu said, ”Okay then, let’s test your affinity. For Saya, her affinity is fire, as all Uchiha have. And she has been training for it even before the academy. I have no idea about you two.”

Fumi asked, ”How do we test the affinity?”

Ryu said, ”Leave that to me. Tomorrow is a holiday; meet me at my home. I have something for all of you. And bring Kaito too. ”

After this academy class, Ryu went straight to Tsunade.

Tsunade asked, ”You are done with the classes.”

Ryu replied, ”Yes, I am. Those boring classes are a pain in my butt.”

Tsuande said, ”I told you to come with me. Homeschooling is not a new concept. All you need to pass is the final exam if you come with me.”

Ryu replied, ”Nice try, but I am not leaving my grandpa to go gambling with you.”

Tsuande was slightly annoyed. She said, ”I had to try. Let’s go, Shizune.”

Shizune asked, ”Where are we going?”

Tsunade replied, ”This brat thinks he has cured TB. I wish to go see for myself.”

Ryu replied, ”This brat did not think he cured it. But he actually did. Lab tests were positive for a reduction in bacteria multiplication. This cure, coupled together with the immune system of the host and TB, will be history.”

Tsunade replied, ”Only if the cure itself is not harmful for the host.”

Ryu said, ”We will find out today. Even if it is harmful, we can find the chemical mechanism behind the reduced cellular growth of bacteria and utilise it somehow. If I have to make a guess, I think the cellular walls of the bacteria are being affected by the dye.”

Tsunade replied, ”That is a very interesting theory.”

Ryu took a self-made prototype Polaroid camera that he had built for some other purpose.

Ryu said, ”I bet Nono-sensei will be surprised to see Aunty Tsunade. It would be funny to see her surprised face. I want to capture it.”

Shizune asked, ”What is this?”

Ryu replied, ”Ohh ... This ... this is a prototype Polaroid camera. I built this for the site survey for the time being. But I plan to launch it in the market after some time.”

Tsuande replied, ”You have too much time on your hands; it looks like I need to increase your training time.”

Ryu replied, ”You can also help me by teaching me shadow clone jutsu. I will use it for a business meeting.”

Tsuande said, ”I will tell you what, kid. If this cure of yours passes the animal testing, I will teach you shadow clone jutsu. But if not, for the next two years, you will come with me.”

Ryu replied, ”You know that you never win bets like that and are called a legendary loser for that reason, right?”

Tsuande’s eyes twitch again in anger.

Ryu said, ”Fine, it’s your loss. The bet is on.”

Shizune smiled and thought, ’Maybe she is betting on her loss. It’s so much fun seeing her happy like this instead of hungover all the time.’

Shizune asked, ”Ryu-kun, how does it work?”

Ryu said, ”The camera has a card inside that is photosensitive. The light it captures reacted with the chemicals on the card, and colours are formed on the spot. It wasn’t that hard to build.”

Ryu said, ”Big sister Shizune, you can take a picture of us and see for yourself.”

Ryu and Tsunade posed for a picture, and Shizune captured the prototype Polaroid camera. The picture came all black.

Shizune said, ”There is nothing in the photo.”

Ryu replied, ”You wait for the chemical reaction to complete.”

They waited, and then the Polaroid film finally revealed a stunning photo of both Ryu and Tsunade smiling.

Tsunade smiled, looking at the photo, and remembered her brother.

Ryu said, ”Aunty, you can keep this one.”

Shizune looked at Tsunade and smiled without saying a word.

Then both Tsunade and Shizune followed Ryu to the Leaf Central Hospital. Nono’s mouth was wide open seeing the legendary Sannin in her lab. Ryu captured her photo, making that awkward face. The flash wakes her up from her surprise, and she notices Ryu looking at the Polaroid card, not knowing that it is her picture.

Ryu said, ”I am going to keep this.”

Nono Yakushi said, ”Lady Tsunade, please welcome.”

Ryu looked at Polaroid with a big grin on his face. When the picture formed on it, Nono saw it, and veins popped on her forehead.

Nono said, ”Give me that. How did you make it so fast? You don’t need processing in the dark room.”

Ryu said, ”Hey, give it back. It is for my collection.”

”If you want to preserve it in a collection for memories, you could have taken a better picture,” Nono said.

Ryu snatched back the photo, and a fight for the photo ensued.

Tsunade intervened and snatched the photo and said, ”I am keeping this so that we may proceed with the task at hand.”

Nonon said, ”Yes, Lady Tsunade, please forgive me for showing you my childish behaviour.”

Tsuande asked, ”How are the infected animals faring?”

Nono replied, ”They are showing signs of TB. They all have high temperatures and decreased activity, showing signs of fatigue.”

Tsuande asked, ”Have you administered the test cure?”

Nono replied, ”Yes. both on a petri dish and a healthy subject. But we are yet to administer it on infected subjects.

Tsunade asked, ”Any side effects on healthy subjects?”

Nono replied, ”We already ruled out any immediate side effects, and now, after a few days of observing, I can confirm no observable side effects as of now.”

Tsuande asked, ”And the results on the petri dish samples?”

Nono said, ”You can see for yourself. These are the photos captured every five hours after introducing the red dye in the dish.”

Tsuande observed the slide photos marked with time and said, ”There is a significant reduction in cell multiplication in the first hour itself.”

Nono said, ”Yes, and the reduction kept on increasing until there was almost no activity.”

Tsuande smiled and said, ”Congratulations, brat. You did it.”

Ryu smiled and said, ”See, I told you you are a legendary loser when it comes to betting.”

Nono thought , ’This brat, even if she is his aunt, has no regard for her.’

She snatched the Polaroid camera from his hand and said, ”Give me that; I am confiscating it.”

”Hey...,” Ryu protested.

Nono looked at the camera and asked, ”You made it...”

Ryu said, ”Yes ... that is the only prototype.”

Nono said, ”You can have it back if you give my photo back.”

Ryu said, ”You can have it. I made it. I can make it again. Besides, there are only 98 photos left in that. Just so you know.”

Nono said, ”Then I am keeping them.”

Tsuande said, ”So what are you going to do with this cure?”

Ryu replied, ”We are going to publish it as a research paper. Starting from how I doubt this dye as a suspected case of an environmental factor for the lack of TB patients.”

Nono thought, ’So this is how he found the dye is effective against TB. I thought he could see the future.’

Tsuande asked, ”You are not going to keep this for yourself.”

Ryu thought, ’Is she trying to test me?’

Ryu said, ”No, I already promised Nono Sensei that both our names will be on this paper, and since I used the survey data collected by the Leaf Central Hospital and also used their lab, it is work discovery, so I am going to leave it open to everyone.”

Tsuande asked, ”Are you sure? You will make a huge loss of money from the vaccine.”

Ryu replied, ”Money is the least of my problems.”

Tsuande thought, ’Not even a shred of greed. He didn’t even hesitate for a second.’

Ryu said, ”You should be more worried about the shadow clone jutsu. I heard it is a high-ranked jutsu. You would need permission from the Hokage’s office.”

Tsuande replied, ”My granduncle, the second Hokage, invented that jutsu. So I have all the rights to teach it. I don’t need permission from anyone.”

Ryu said, ”That is good to hear. I will be waiting.”
