Naruto: They are all reborn.

Chapter 6 Tsunade's Personal Motives

A questioning voice rang out in the classroom.

"Hmm... I understand the logic, but why do ninjas need to master the calculation method for the parabolic trajectory of kunai?"

I was transported to a world with extraordinary powers, thinking that "battle, awesome!" awaited me.

When I opened the textbook, there was nothing else but crooked, crooked pages filled with "Mathematics and Physics." I couldn't sleep, so I carefully examined it all night, finally discerning the conclusion between the lines: You've been transported, but have you really?

"It doesn't really mean anything to a kunai thrown by a ninja, but this knowledge is used in conjunction with another course."

After saying that, Nohara Rin took out a textbook titled "Trap and Mechanism" and continued her explanation.

"The vast majority of traps use poisoned kunai as their lethal weapon. Setting up, dismantling, and dodging all require calculating the approximate path of the kunai after they are launched from the trap. Not every ninja has enough adaptability; prevention is the best approach..."

"Once you master these abilities, they will be incredibly effective against the puppets of Sunagakure."

Shi Xu nodded thoughtfully, then asked, "Wait, what is Sunagakure? And what are puppets?"

Nohara Rin pondered for a moment, looking somewhat troubled: "It seems that the priority for catching up on ninja knowledge is general knowledge of the ninja world, rather than the knowledge in textbooks."

"I'm sorry to have troubled you." Shi Xu scratched the back of his head, feeling a little embarrassed.

Nohara Rin shook her head, her voice still as gentle as ever: "This is not your responsibility."

Blame it on the war.

This was the unspoken part of her statement. She had only thought of tutoring Shixu because of what happened that morning, and she certainly couldn't reopen old wounds.

Nohara Rin continued to tutor Toki, explaining the characteristics of the five great nations and five great ninja villages, the relationships of restraint between the five basic ninjutsu attributes, and bloodline limits.

He just lacked some common sense, not stupidity. He was essentially an adult who was already eighteen years old before he transmigrated, so Nohara Rin taught him quite easily.

After school, at the school gate.

"Anyway, thank you all for today. I'll treat you to a meal when the time is right."

Shi Xu bid farewell to Kakashi and the others, then turned and went home.

Not long after I stepped outside, I happened to see a green figure "rushing past"—literally rushing, because its two legs were kicking wildly in the air.

Shi Xu couldn't help but call out to him, "Kai, is there some deeper meaning to walking upside down like that?"

Might Guy stopped, braced himself with his hands, and landed in front of Shi Xu with a beautiful backflip.

"My dear friend! Walking upside down can strengthen your arms. Want to train with me?"

Shi Xu's lips twitched slightly: "No, I've never done any physical training before. If I start doing such high-intensity training with you right away, my body won't be able to handle it."

"That makes sense, but I can also think of a training plan for you." Might Guy didn't insist, but he really wanted to do his best for his best friend.

After thinking for a moment, Shi Xu politely declined, saying, "I'll follow my teacher's arrangements."

"Hmm...that's fine too!"

Matt Kai looked a little frustrated, but it only lasted for less than a second before he was full of energy and returned to the position of supporting himself with his hands on the ground.

"Shi Xu, see you tomorrow."

"Okay, see you tomorrow." Shi Xu watched him leave.

Back at the Senju residence, a strong smell of medicinal herbs filled the air even before entering. Did Tsunade-sensei bring the entire herb garden back with her?

A pot was set up in the front yard, and Tsunade sat on a small stool next to it, boiling the medicinal herbs with a wooden spoon.

When she saw Shi Xu coming home from school, she immediately called out, "Shi Xu, come here and drink this."

Shi Xu took the bowl, which contained a small amount of brown liquid. The smell of Chinese medicine wafted into his nose and rushed straight to his brain, powerful and unobstructed.

He pinched his nose and downed it in one gulp, the bitter taste lingering on his tongue: "What is this?"

"It's a powerful tonic, but you can only drink half a bowl a day; you can't handle more than that."

"What about this one in the pot?"

"This is for tonight's bath. Go find Kushina now and do some physical training so that the tonic you just drank can take effect as soon as possible."

"Yes, ma'am!" Shi Xu hurriedly went in to pour himself some water, and drank three large cups in a row to wash away the bitterness in his mouth.

He then walked to Kushina's door and knocked lightly.

"They're here."

Before long, Kushina came out dressed and ready: "Let's go! Let's go to the training grounds."

Kushina's training regimen was very simple, mainly consisting of running, jumping, squatting, etc. These training methods can quickly activate cardiovascular function and strengthen thigh muscles.

The thigh muscles are the largest muscle group in the human body. The best way to gain endurance for long-term, tireless training is to train your legs.

Under Kushina's strict supervision, Tokio had almost no chance to slack off. Even when he was completely unable to run, she would drag him and force him to run.

In the end, Toki was carried back by Kushina; he didn't even have the strength to move a finger.

Not a single mistake, not a single poem, not a single post, not a single piece of content, not a single look!

The courtyard was deserted, and the liquid in the pot was almost gone. It bubbled once under the heat of the flames, and then exploded.

"We're home." Kushina said, but didn't get the response she expected.

She looked back and saw that Shi Xu had fallen asleep on her back, his head buried in her neck, his breathing even and long.

She's so exhausted, she probably won't wake up anytime soon.

Kushina sighed softly, but rather than feeling helpless, her sigh sounded more like one of indulgence.

Tsunade came out of the house carrying several medicinal herbs. Seeing the two of them, she immediately said, "The medicinal bath is ready. Kushina, please help put Toki in it."

She nodded and walked toward the bathroom.

Just then, Tsunade's voice came from behind.

"Oh, and remember to take off your clothes, all of them."

"Huh?" Kushina paused, her long hair falling down to cover her flushed cheeks.

She instinctively wanted to pass the task to Tsunade, but when she looked back, she found that Tsunade was completely focused on brewing the medicinal herbs and couldn't leave.

"Where's Grandma Mito?"

Without looking up, Tsunade replied, "Grandma Mito has been very busy these past few days, working with the Hokage to investigate spies in the village. They've already caught quite a few spies from Kumogakure."

"Well... okay then."

Kushina seemed to have made up her mind and walked step by step toward the bathroom.

Unbeknownst to her, Tsunade behind her was wearing a strange smile, which became increasingly undisguised after she left.

In their past life, the Hidden Cloud Village orchestrated a kidnapping, successfully exploiting a weakness in the Leaf Village's defenses and abducting Kushina from her home.

Fortunately, Shio didn't go to school that day. He found traces left by Kushina at home, sent a signal to notify the village, and immediately followed the traces.

After finding Kushina, Toki risked her life to buy time for the village's reinforcements, resulting in one of Kushina's deaths and another injury. By the time Tsunade arrived, Toki was already half-dead and on her way to meet the Sage of Six Paths; she almost couldn't save her.

Although she was a bit disheveled, Kushina fell in love with Toki because of this heroic rescue.

But this time, there won't be that chance, so Tsunade can only try to bring the two of them together as much as possible.

"Oh dear—I'm so worried about this."
