After traveling through time, I became friends with Tsunade

Ninja Alliance, Medical Headquarters.

The place was filled with a tense and busy atmosphere; even in the conference room with its door closed, one could hear the groans of the wounded.

Tsunade already had Yusuke's Flying Thunder God mark on her body. Because the security here was too strong, in order not to attract attention, he could only use the Flying Thunder God technique to sneak in silently.

Tsunade was now organizing several assistants to use slugs to disperse chakra to treat the wounded.

Yusuke's sudden appearance scared them. At that moment, everyone's eyes were focused on Yusuke, with surprise in their eyes.

But he heaved a sigh of relief after seeing who was coming. However, Yusuke obviously underestimated the professionalism of the barrier class.

As soon as Yusuke appeared, several teams of ninjas quickly surrounded him, looking at the intruders with vigilant eyes.

Looking at Yusuke's embarrassed expression, Tsunade couldn't help but cover her mouth and laugh, with a hint of teasing in that smile.

"The Fourth Hokage-sama!"

When they found out it was Yusuke, they immediately said respectfully, Yusuke nodded slightly, "I'm here to talk to the Fifth Hokage about something, you all go down."

"Yes!" The ninjas retreated quickly.

"You go summon the slug first, I'll go over later and remove the Yin Seal when the chakra is insufficient."

Tsunade immediately spoke to Shizune and the other girls, her expression also extremely serious.

As Yusuke's bedmate, she already knew Yusuke's character. It seemed that something happened on her side, otherwise why would he come here suddenly?

We all know that Akatsuki launched this war just to get the remaining tailed beasts, not to mention that the first battle has just ended and it is the busiest time for the medical department.

"Tsunade, this is all I can tell you."

Yusuke took Tsunade's hand and sat down again.

"I have already felt that some White Zetsu took advantage of the chaos on the battlefield and secretly killed the ninjas and exchanged their identities with them."

Just now, Yusuke used Isobushi's chakra to explore it once.

However, Isobushi is not the Nine-Tailed Fox, so there will definitely be some fish that slip through the net.

"Swapped identities? Does that mean the enemy has infiltrated the medical department now?"

Tsunade immediately realized the seriousness of the matter, and a hint of shock flashed in her eyes.

No wonder Yusuke came here quietly. It turned out that he wanted to guard against these White Zetsu in case they became desperate.

“Yes, but we know this but cannot say it, because anyone coming down from the battlefield now could be an enemy.

There weren't many in the medical department, but Isobushi's chakra could sense a little.

But I am afraid that it has already infiltrated into various units, and that is the most difficult problem."

Yusuke's expression became more serious, he knew the difficulty of this matter.

Seeing Yusuke's serious expression, Tsunade did not hesitate at all, "Don't worry, I won't let the medical department suffer too much harm."

"Who? Lady Tsunade is busy. Please go back to your own duties."

The guards at the door stopped those who wanted to break in and shouted at them to leave.

"We have business to seek out Lady Tsunade, and we won't disturb her for long."

"Isn't that Sakura and Ino's voice? Why are they in the medical department too?"

Yusuke asked curiously when he heard the sound outside the door.

There was a hint of confusion in his eyes, and he was obviously surprised by their appearance.

"I don't know either. I just took over temporarily, but they should be apprentices who have just joined the medical team. Let them in."

After Tsunade and Yusuke explained, they shouted and asked the guards at the door to let them in.

What apprentices? They were probably forced in by their teachers or parents in order to take part in the war.

Yusuke estimated that they might not even have learned a single medical ninjutsu, and their only role here might be to help people wrap gauze.

"Lady Tsunade! And... the Fourth Hokage!"

The three of them blushed, including Hinata, who had been silent just now, probably thinking of something she shouldn't have thought about.

However, they never dreamed that someone with a higher status than the supreme commander of the coalition forces would appear here.

Tsunade also glanced at Yusuke. Didn't they say it should be kept secret? How could they expose it in front of the juniors?

"What are you doing here?"

However, Tsunade still smiled and asked them. Her voice was gentle and kind, which made people feel at ease.

"We...we want to become Tsunade-sama's apprentice and learn medical ninjutsu so that we can save more injured people."

Haruno Sakura and the other two bowed deeply in request, their eyes full of anticipation.

Tsunade did not show any surprise, as there were many people who came to her to become her disciples.

However, except for Haruno Sakura, the other two have a deep relationship with himself or Yusuke.

"You should do the most basic things first. We will arrange for the three of you to help under the medical corps' jonin. If you perform well, I can consider it after the war is over."

You're going to run away after the war, right? Yusuke looked at Tsunade who was rejecting people seriously, and he acted quite well.

"You guys go down, I have something important to discuss with the Fourth Hokage. By the way, you cannot reveal the Fourth Hokage's presence here. This is confidential!"

"Yes!"

Haruno Sakura and the other two immediately agreed and hurriedly left. Their movements were swift and respectful.

"Okay, what else? You know I'm busy."

Tsunade immediately stretched lazily, with a hint of fatigue in the movement.

Yusuke immediately grabbed her shoulders and began massaging her, and then whispered his guess into her ear.

......

Late at night, most people had fallen into a deep sleep. The entire camp was shrouded in silence, with only the occasional sound of the wounded talking in their sleep.

After a day and night of fighting, they were already very tired.

Only one-tenth of the total number of ninja coalition forces were on night watch duty. They were all extremely alert, with vigilant eyes, always paying attention to the movements around them.

The medical ninja, who had been busy all day, had just finished washing up and was ready to return to his tent to rest.

Fortunately, the total number of medical ninjas provided by Konoha is more than that of the other four ninja villages combined. Now the injured have received preliminary treatment, and only the medical ninjas on duty at night are left.

Ino and Hinata are both famous nobles from Konoha. Although neither of them looks down on civilian ninjas, they still have more topics to talk about when they get along with each other.

When they finished washing up, they returned to the tent and saw Haruno Sakura already sleeping soundly.

The two did not feel anything unusual. They were indeed very tired today, not only because of bandaging the wounded, but also because it was the first time they had experienced such a thing.

To be honest, they did the same thing, then they lay down and fell asleep directly.

At this time, Sakura changed her face...
