"Summoning out a Katsuyu like Tsunade's before reaching Chakra saturation?"
Inside the command tent, upon hearing the report from his subordinate, Shimura Danzo's face showed numerous expressions. Naturally, he knew about Tsunade's Summoning beast and understood that Summoning the special Katsuyu like Tsunade did wasn't an easy task.
He just hadn't expected that Tatsuma, coming from a civilian background, could exhibit such Chakra levels to Summon a Katsuyu of that size. For a moment, Danzo recalled the blood samples he had Orochimaru research before.
Orochimaru's research concluded that everything was normal; Tatsuma and Minato were just ordinary civilian descendants. Out of trust in Orochimaru's abilities, Danzo didn't have his own research team reexamine the matter.
After all, he had already asked his research team before, but unfortunately, his team wasn't yet powerful enough to study blood traces and could only determine if someone was healthy through blood tests.
But now, looking at it, Orochimaru's research couldn't be trusted either. It's just unclear whether Orochimaru deliberately provided him with incorrect research reports or if Tatsuma at the time truly hadn't yet revealed his talent.
As Danzo pondered, his mind recalled that rumor, a talent that was similarly extraordinary, with a strong resemblance in both form and spirit, along with immense Chakra. Danzo spoke up:
"Have those remaining in the village investigate whether Sakamoto Tatsuma showed any changes during his several returns to the village, whether those around him reacted strangely to Tatsuma's presence, and... look into whether Orochimaru has any new research."
"Yes, Danzo-sama."
The ANBU operative acknowledged the orders and swiftly departed. Danzo then glanced outside the door, murmuring softly, "I am the one who inherited sensei's ninja way. If you truly have any connection to sensei, then the one who should have you is me, not that weakling Sarutobi."
Inside the medical camp, with the assistance of the split forms of Katsuyu, Tatsuma swiftly aided the injured in treating their wounds. With Katsuyu's Chakra assistance, Tatsuma didn't need to worry about triggering secondary bleeding when excising necrotic flesh; he only needed to swiftly remove, clean, and suture the wounds.
The Chakra blade formed in his hand was extremely precise; as it passed over the patients' bodies, they could only feel their flesh being cut open, with almost no sensation of pain.
After finishing the patients requiring surgical procedures, it was already late at night. Tatsuma didn't push himself and instead went to sleep. He returned to the medical camp the next day after having breakfast.
The remaining cases were not easily resolved with surgery alone. Many patients had organs or bone marrow invaded by viruses. Tsunade's antidote could neutralize toxins in the bloodstream but couldn't counter those invading internal organs.
However, antidotes were primarily designed for battlefield use. If there were medical ninjas present, such toxins weren't considered lethal. Previously, Tsunade alone had saved the lives of hundreds of heavily poisoned patients and developed various antidotes.
Tatsuma couldn't replicate the latter part, but as for the patients before him, he believed he could handle them.
As he sat on a vacant hospital bed in the medical camp, jotting down notes, Tsunade also arrived at the camp, intending to complete the work left unfinished from the previous day.
Seeing that her disciple hadn't begun treatment but seemed to be devising a treatment plan, Tsunade became curious. She approached Tatsuma and asked, "Do you not know how to treat these people?"
"Just the Delicate Illness Extraction Jutsu will suffice. It's just that the efficiency is too low. I only have two hands, yet there are fifty to sixty patients here. If I use the Delicate Illness Extraction Jutsu, it will take at least three to four days to resolve," Tatsuma replied.
Upon hearing this, Tsunade nodded. If it were her, she wouldn't use the Delicate Illness Extraction Jutsu either. Instead, she would research targeted medicines for internal organs and bone marrow. However, Tatsuma hadn't learned about these aspects.
Tsunade suddenly grew curious about how Tatsuma would handle the situation. She glanced at the notebook in Tatsuma's hand, seeing various techniques written on it. She furrowed her brow and said, "Are you sure? Can your Chakra control and the manipulation of Chakra forms really support this jutsu?"
"Let's give it a try. If I can't handle fifty at once, then I'll try ten at a time. If that's still too much, then I'll try five at a time," Tatsuma responded confidently.
Tatsuma spoke as he closed the notebook in his hand. Despite having Ninjutsu Development, it was still very difficult for him to create a Ninjutsu out of thin air. After all, his understanding of various Ninjutsu was still limited, and his training in Chakra Nature Transformation had not yet reached its peak.
However, based on his existing knowledge of Ninjutsu, summarizing and then innovating, making modifications and adjustments to some Ninjutsu, was still achievable.
Forming seals to refine Chakra, this time Tatsuma refined Chakra to a state where his body could fully contain it. Then, he performed the Summoning Jutsu with seals, and the enormous Katsuyu reappeared.
"Are we continuing yesterday's treatment, Tatsuma-kun? Oh, Tsunade, you're here too," Katsuyu said with a hint of joy in her tone, as if she thoroughly enjoyed the process of treating patients. Tsunade also greeted Katsuyu, and Tatsuma nodded, continuing to refine Chakra. After saturating his cells once again with Chakra, he addressed Katsuyu:
"Katsuyu-sama, I need to share all of your senses and utilize your body to perform Ninjutsu."
"Is it Tsunade's Network Healing Jutsu?" Katsuyu asked. Tatsuma nodded and then shook his head, saying, "It's a variant of the Delicate Illness Extraction Jutsu. This is my Chakra; please accept it."
With that, Tatsuma formed seals, completing the practical application of the jutsu within his body. A faint yellow transparent Chakra membrane appeared. Tatsuma reached out his hand and placed it on Katsuyu's body, while his Chakra was continuously drawn out in that moment.
"Phew..."
With almost depleted Chakra, Tatsuma halted the Chakra transfer and said, "Katsuyu-sama, could you please split into double the number of patients here? Each patient will need assistance from two Katsuyu."
"Alright, then my senses and Chakra are yours," Katsuyu replied.
With that, Katsuyu lowered her head, and her antennae lightly touched Tatsuma's forehead. Between Tatsuma and Katsuyu's foreheads, there appeared an additional strand of blue Chakra. Suddenly, Tatsuma felt his vision and sense of touch becoming extraordinarily strange.
However, this wasn't the first time he had shared senses with Katsuyu. They had attempted it during Tsunade's teaching sessions before, so by the time Katsuyu split and lay on the patients, Tatsuma had already adjusted.
Quickly refining some Chakra, Tatsuma closed his eyes. His vision didn't disappear because of the closed eyelids. Instead, hundreds of images appeared in his mind, like a security guard monitoring surveillance cameras in a control room.
Taking a deep breath and concentrating his mind, Tatsuma's hands began to gently wave in the air, infusing the Delicate Illness Extraction Jutsu with Chakra previously bestowed on Katsuyu into the patients' bodies.
This caused some unconscious patients to instinctively resist. At this moment, Katsuyu's split bodies timely injected some Chakra used for calming and anesthesia, pacifying them.
Tsunade, who had originally intended to treat critically ill patients, didn't leave but stayed by Tatsuma's side. As an excellent medical ninja, Tsunade naturally understood what Tatsuma was doing at this moment.
"Performing such meticulous surgeries on over fifty ninja simultaneously... truly insane," she thought to herself.
Even Tsunade had to admit that Tatsuma's current idea was crazy. If one mistake occurred and the Chakra used for treatment remained in the patients' bodies, it would instantly turn into lethal Chakra.
Individually, the Delicate Illness Extraction Jutsu wasn't difficult, at least Tsunade felt that way. After all, it wasn't as challenging to master as the Mystical Palm Jutsu. However, simultaneously using it on fifty people...
Watching Tatsuma's Chakra actually invade the bodies of over fifty patients simultaneously, Tsunade squinted. If Tatsuma had even a slight additional thought in his mind at this moment, all fifty surgeries would likely fail simultaneously.
Tsunade's attention was heightened to the extreme. She wouldn't allow anyone to disturb her student at this critical moment.
At this moment, Tatsuma's brain was rapidly processing all the received information. He was grateful that he had chosen "Divine Mind" when amplifying his abilities; otherwise, he wouldn't have been able to manage such a task of dividing his mind among fifty individuals.
However, while his processing speed was sufficient, the bandwidth was still a bit lacking. He could handle all this information simultaneously, but he couldn't process any single piece of information at the same speed as he normally would in one-on-one situations.
After quite some time, Tatsuma completely used Chakra to identify the toxins in the bodies of these patients. Then, slowly, with the assistance of another Katsuyu split body on each patient, which also possessed Chakra imbued with the Delicate Illness Extraction Jutsu, he began to draw out the toxins.
Only after the toxins were completely removed from the patients did Tatsuma open his eyes. Then, his eyes rolled back, and he almost collapsed, but fortunately, Tsunade caught him in time.
Watching Tatsuma, with pale lips and sweat dripping from his forehead, Tsunade chuckled and said, "Even prisoners who have undergone interrogation with the Yamanaka Clan Secret Jutsu don't look as miserable as you do now."
Tatsuma could only hear buzzing in his ears; he didn't catch a word of Tsunade's remarks. Tsunade also understood Tatsuma's condition. She laid him down on the bed and took over the work of controlling Katsuyu.
She concentrated the toxins collected by Katsuyu and sealed them in bottles with Sealing Jutsu. Then, she ended the Summoning, giving Tatsuma a meager amount of Chakra to replenish his strength.
Tatsuma's Medical Ninjutsu just now could be described as pushing to the absolute limit. Tsunade had been tempted to take over several times, but ultimately, she chose to trust Tatsuma, and he performed remarkably well.
However, it was already noon. Tsunade found some physiological saline and glucose solution for Tatsuma and hooked him up. Then, she entered the intensive care unit to start treating the critically ill patients.
Tatsuma slept directly from noon that day until the early morning of the next day. When he woke up, he looked around anxiously, fearing that his Medical Ninjutsu had failed at the last moment.
When he saw that there was no one left in the camp, he suddenly felt a bit panicked, wondering if something major had happened. Just then, a reassuring voice spoke up.
"You can record this technique and submit it as a forbidden jutsu to the village. However, your technique is probably one that no other medical ninja can use," said the voice.
"Sensei?" Tatsuma looked in the direction of the voice and saw Tsunade, who had come in from outside the camp, flipping through his notes. Upon seeing Tatsuma, Tsunade smiled rarely and said, "Your surgery was very successful. All fifty-six critically poisoned patients have been cured."
