From Konoha Hidden Village to the border of the Fire Country, with the footsteps of ninjas, it only takes two days or even less than two days to rush to the full force, but the speed of the large army will inevitably slow down.

First, because it is difficult to coordinate with a large number of people, unlike three or five people who can adjust the speed at any time, in the case of a large number of people, they can only rely on reducing the speed to maintain the formation.

The second is that large units are easier to target, unlike small teams that are flexible and difficult to detect, so when large troops advance, they must let the perceptual ninja reconnoiter first, and the upper limit of the speed of the large force will not exceed the reconnaissance speed of the perceptual ninja.

Tatsuma originally applied to join the reconnaissance team during the rush, after all, he is also very talented in perception, although the amount of chakra cannot support him to perceive reconnaissance for a long time, but it can also play a substitute role.

It's just that Tsunade refused, because the reconnaissance team was in front of the large force, which was easier to encounter the enemy, and after a few days of hurrying, the large force also encountered several attacks and killed two sentient ninjas.

It took more than four days for the large army to arrive at the camp on the border, and the border between the great powers was garrisoned by ninjas all year round, and the war had not really broken out at this time, and the camp had not been destroyed.

Therefore, the large army does not need to re-establish the camp, but directly connects with the original ninjas in the camp.

However, as soon as he arrived at the camp, Tatsuma ushered in his first mission, which was to cooperate with the medical team to treat the ninjas in the camp.

"Kazuno, you assist Tatsuma, treat the ninjas who have been seriously injured, take me to see those poisoned ninjas, and others are flexible and arranged, and the cases that can't be solved are waiting for me to come over."

Tsunade handed over the docking work to Orochimaru, and she directly took the medical team to the wartime medical department, and the medical team heard Tsunade's arrangement, and after subconsciously glancing at Tatsuma, he also quickly ran towards the wounded.

At this time, a sixteen or seventeen-year-old girl walked up to Tatsuma and said, "Hello, Sakamoto Tatsuma, my name is Mito Gate Kazuno, and I am the former person in charge here, please come with me." ”

Tatsuma nodded, not complaining about the start of work when he first arrived, and followed Kazuno into a tent with his backpack on his back.

There was a strong smell of potions in the tent, and there were four or five ninjas lying on the hospital bed moaning, or holding the quilt and trembling constantly, Tatsuma took a closer look at the situation of the most recent injured person, frowned and asked:

"Who did the previous treatment?"

The scar wound was on the thigh, it should have been caused by some kind of wind escape ninjutsu, the outside was all cut open, and the bones were also slightly damaged, but the most serious was not a cut wound, but an infection.

Hearing this, Kazuno looked at Tatsuma's frowning expression, and said with some embarrassment: "It's me." ”

"Didn't there be a medical ninja in the camp before?"

Tatsuma stepped aside, unloaded his backpack and asked, Kazuno's face turned red, and she was expelled from the medical ninja membership? But she could only say with shame:

"Medical care is limited here..."

Tatsuma didn't listen to her powerless convenience, put on a mask and gloves, and then Tatsuma took out a bundle of sealing scrolls from his backpack, and after unsealing, more than a dozen bottles of salt water and hydrogen peroxide appeared.

Picking up two of the bottles, as well as a pack of medical needles and threads, masks, and gloves, Tatsuma returned to the hospital bed and asked, "Will you stitch up the wound?" ”

Hearing this, Kazuno hurriedly nodded, and Tatsuma said: "I will cut off the infected and purulent part of his wound, and you can suture it to stop the bleeding, and then you can use the palm immortal technique or other ninjutsu to assist in treatment." ”

If it is a wound that has just been received, then as long as there is no dirt in the wound, you can use the palm immortal technique directly, but this ninja's wound is suppurated, and it is not suitable for using the palm immortal technique.

Kazuno nodded, subconsciously took the things handed by Chenma, and after reacting, he put on a mask and gloves like Chenma, and Chenma said casually: "Remember to wrap your hair next time." ”

"I see."

Suddenly, Kazuno had the feeling that she had just graduated from the ninja school a few years ago and was assigned to an internship at the Konoha Ninja Hospital, and Tatsuma was like the director who took her at the time, but... The director is just fierce and doesn't teach anything.

Tatsuma observed the wound and talked to the injured ninja for a few words, and then began to move, the chakra in his palm condensed, and a scalpel composed of blue chakra appeared, directly slashing around the patient's wound.

He did not use anesthetic drugs to assist, because the patient's wound was tightly bandaged around to stop the bleeding, and he was almost unconscious at this time, what other anesthetic?

Cut off the infected and purulent area, then rinse with hydrogen peroxide and saline, and tell Kazuno how to stitch it up, Tatsuma took off his gloves and masks, changed into new masks, and walked to the next hospital bed.

The next one was not so lucky, he was injured in the ribs, his lungs and stomach were affected, and Tatsuma just debrided him to stop the bleeding, and he couldn't handle such an injury, so he had to hand it over to Tsunade.

The next few were lucky, the wounds were all in the limbs, only one was in the buttocks, and they only needed to remove the infected part and clean up and suture it again, and after doing this, Tatsuma looked at Kazuno with strange eyes.

He remembered that Tsunade had asked Kazuno to take him to treat a serious injury, how could it be... Such a basic injury?

If it wasn't for the previous wound treatment error, it only needs to be debrided and sutured, even if you don't know how to treat ninjutsu, you won't be infected like this, right?

Or is it that the person in charge of Kazuno is fake... Wait a minute... Mito Gate... Tatsuma looked at Kazuno Mitomon and felt like she had come to gild.

Kazuno, who was deeply bowed by Tatsuma, was a little aggrieved, she was indeed a medical ninja, but she had never dealt with this kind of injury that was very likely to bleed too much in a short period of time and died.

In order to prevent these injuries from dying of excessive blood loss, she can only stop the bleeding urgently, and then use various hemostatic drugs, hoping for a miracle.

Tatsuma, who thought he had guessed the truth, didn't say anything anymore, after all, after the ninja clan, he was a civilian who couldn't comment on it, and it wouldn't be good if he was put in small shoes in the future.

He checked the wound that Kazunai had re-stitched, and it could only be said that it was unsatisfactory and not pretty, but at least the stitches were quite successful, and after untying the surrounding bandages, the blood was restored and there was no bleeding again.

Only then did Tatsuma use the palm immortal technique to speed up the recovery of the patient's wounds, and there were only four patients in total who needed his treatment, and even Tatsuma would not be so weak that he needed to rest halfway.

But after all, several people have a large piece of flesh on their bodies, although the wound is healed, but it will take some time to recover before they can continue to participate in the war, and after letting them sleep, Tatsuma is sorting out the case report and surgical plan of the patient whose internal organs are damaged.

Tatsuma didn't study medical ninjutsu in depth, but after following Tsunade for more than half a year, he saw a lot of cases, and although he didn't know how to do it, he still relied on his memory to introduce the surgical plan of several excellent cases.

Anyway, after these things are sorted out, Tsunade has to go through it again, and if he guesses correctly, he can save some time for Tsunade, and even if he guesses wrong, he won't waste Tsunade's time extraordinarily.

"Yes, do you want to change your mind and learn medical ninjutsu from me?"

Tatsuma in the book suddenly shook, a big hole appeared in the paper, and when he turned around, he found Tsunade looking at him with a satisfied smile, Tatsuma took a deep breath and said:

"Teacher, people are scared to death. By the way, the poison on your side was solved so quickly? ”

"It's all the inventory of Shayin Village, and there are ready-made plans."

Tsunade picked up the plan written by Tatsuma and looked at it, compared the case again, and said, "You don't have to fight and kill to be a ninja, I think you have the talent to be a medical ninja." ”

"Forget it, I still don't like the atmosphere in the ward, and... It's not that I don't dare to kill people because I'm cowardly, it's just... Never mind. ”

Tatsuma guessed that Tsunade had fooled him again and again about the purpose of transferring to medical school, but he still refused, and Tsunade nodded, and no longer advised, but said:

"Let's go to other wards, the medical conditions here are too poor, you can go and help."

"Okay, teacher."
