"Alright, Sister Rin, didn't you say you needed my help? Let's get started."
Feeling somewhat embarrassed and helpless under the misunderstanding looks from the two, Kōki quickly changed the subject and asked Rin Takakura.
"Oh, right, I'm so happy to see you, Kōki. I forgot we still have many patients to treat. Uncle Genji, let me take Kōki to get used to things first, and we can have a proper chat after we're done."
"Okay, you guys go ahead, I need to continue here too."
After greeting Genji Ryōma, Rin Takakura led Kōki to a heavily injured ninja, then pointed at the ninja and said to Kōki, " Kōki, watch me operate first, and then you can act when I ask for your help."
Although Kōki's Medical Ninjutsu was quite good, Rin Takakura didn't dare let Kōki do it directly.
After all, these are matters of life and death, and cannot be taken lightly.
All medical-nin capable of providing direct treatment have undergone rigorous training and mastered several human healing techniques before being sent to the front lines.
Only someone Kōki, who only knows Medical Ninjutsu but doesn't know how to use it properly, needs this stage.
After giving instructions to Kōki, Rin Takakura turned to the heavily injured ninja in front of him and began to examine his wounds.
The ninja had been stabbed in the chest, but luckily the wound wasn't to his heart, saving his life. He also had multiple wounds on his arms, and his cells had atrophied to varying degrees, clearly the result of excessive strain on his cellular energy. He was now in a coma.
However, Rin Takakura believed that these problems were easy to handle, as she could cure them simply by using her Medical Ninjutsu.
The key issue is that while this ninja suffered these external injuries, he also had the Sunagakure's secret toxins inside his body, which were constantly damaging his internal organs.
The main reason why Rin Takakura couldn't save the seriously injured ninja was that there was no antidote for this poison in the camp.
Even if she heals all the ninja's injuries, if she cannot remove the deadly poison from his body in time, the ninja will still only die.
After analyzing the severely injured ninja's condition, Rin Takakura felt a sense of unease. It wasn't that she couldn't handle it, but rather that she couldn't simultaneously address both the detoxification and the wound treatment. No matter which aspect she treated first, the other would inevitably flare up at the right time, still potentially killing the ninja.
Besides, she didn't have much time to think. The ninja's heart rate was slowly dropping; if she didn't act soon, he was doomed.
" Kōki, I remember you're Delicate Illness Extraction Technique, right?" Rin Takakura said to Kōki while cutting open the patient's wound with Chakra Scalpel.
"Yes, I know this technique. Are you planning to let me use it, Sister Rin?" Upon hearing Rin Takakura's sudden question, Kōki had a guess in her mind.
"That's right. I originally wanted you to take a look first, but the patient doesn't have much time left, and I can't handle it alone, so I have to ask you for help."
Rin Takakura was also helpless. She had originally hoped that Kōki would watch her operate the equipment first and learn for a period of time before she tried it herself.
Unfortunately, time is of the Kōki Yuki no Uehara, that ninja will only die. And it's impossible to get help from others, because they are all dealing with seriously injured patients and can't get away.
" Kōki, I'll now cut open the patient's wound. Can you use the Delicate Illness Extraction Technique to draw out the toxins from the wound?"
"No problem, don't worry, Sister Rin." Rin Takakura 'Kōki request a piece of cake; he had long since mastered the Delicate Illness Extraction Technique, and it posed no difficulty for him whatsoever.
In other words, he lacked experience. If he had experience, he would have been able to do it himself without Rin Takakura's instructions.
"Alright, let's begin." At this moment, Rin Takakura had already cut open the patient's main wound, and then used her hands to perform Medical Ninjutsu to stabilize the vital signs of her Genin.
These wounds were surrounded by obvious purple marks, which were the areas that Kōki needed to treat using his Delicate Illness Extraction Technique.
This ninja was lucky; the poison didn't spread to his heart, otherwise it would have been even more difficult to treat.
Upon seeing the wound exposed, Kōki placed his hand into a container filled with a special medicinal liquid, used his Chakra to absorb the liquid, and then controlled the liquid to cover the patient's purplish, oozing wound.
As soon as the medicine was applied to the wound, the patient let out a painful scream, and his body involuntarily trembled to some extent. Fortunately, Rin Takakura was prepared and used Medical Ninjutsu in conjunction with other medicines to suppress the patient's restless body, preventing the trembling ninja from interfering with Kōki's performance of the technique.
After enveloping the poisoned wound with this special medicinal liquid, Kōki manipulated his Chakra to gather the toxins around the patient's wound and extracted them all in one go. As the toxins disappeared, the patient's wound changed from its initial eerie purple color to a normal blood red.
Then Kōki continued to treat all the remaining wounds in the same way, which finally cleared all the toxins from the patient's body.
Seeing that Kōki had cleared the toxins, Rin Takakura also began to exert her power, directly transforming the ordinary healing spell in her hand into a higher-level Mystical Palm Technique.
With the help of Kōki and Rin Takakura, the critically injured ninja was successfully rescued, and the painful expression on his face returned to calm.
However, this only indicates that the ninja's injuries have been healed. He will still need some time to fully recover and wake up, as excessive blood loss was one of the reasons why the ninja remained unconscious.
"Phew!" After successfully saving the ninja's life from the Pure Land, Rin Takakura breathed a sigh of relief. Although she seemed to trust Kōki, her heart had actually been in her throat the whole time.
Because the most challenging aspect of the Delicate Illness Extraction Technique is the practitioner's ability to distinguish between normal cells and toxins. If the practitioner fails to differentiate between them, it is easy to extract the patient's normal cells, causing greater harm to the patient.
After all, there's a difference between learning and using. Learning only means you can use the technique; truly mastering it means curing the illness. Fortunately Kōki didn't disappoint her.
For the next half day, Kōki stayed by Rin Takakura's side, assisting her.
Although Kōki wasn't allowed to heal the wounds on her own, Kōki gained a lot of experience in treatment. For example, she learned the order of using certain medications, how to allocate Chakra when using healing techniques, and how to distinguish which wounds required healing techniques and which could heal normally with medication.
This was all knowledge he had never encountered before; indeed, practice is the best teacher.
