In Konoha, you get one evolution point every day.

The training order for Rasengan:

First, gather chakra in your palm.

Second, use chakra to pop a water balloon.

Third, make a water ball and use chakra to shatter it.

Fourth, let's go back to step one.

Lin Fan then instructed Minato and Kakashi in the order described above.

Minato suddenly realized.

"You used a transformation technique to learn this, didn't you?"

No, it's a technique from the original work.

However, Minato clearly didn't understand the power of the original work and continued to explain things to Lin Fan on his own.

"Schools usually recommend training in the form of the fewest hand seals when teaching Transformation, Clone, and Substitute techniques because the Three Body Techniques use only one hand seal, so even if the user fails, the user will not be in danger."

"Furthermore, this hand seal method allows the user to master the knives of ninjutsu more quickly."

"And Mr. Lin Fan, you actually came up with two methods—water balloons and water balls—to help people quickly adapt to the Rasengan technique, using the Ninja Academy's curriculum... You're truly a genius!"

No, I didn't, don't talk nonsense.

Lin Fan nodded.

"you're right."

After he finished speaking, he looked at Kakashi.

Kakashi has already begun to try the first step: gathering chakra in his palms.

Blue chakra pulsed in his palm.

However, those without the Sharingan cannot see it.

Because Kakashi's chakra wasn't compressed enough.

"It's very difficult." Kakashi looked at his palm and was somewhat disappointed that he couldn't even see a trace of chakra.

Lin Fan immediately comforted him.

"Don't worry, it will happen."

After all, you're going to be the Copy Ninja Kakashi in the future!

If Obito doesn't give you eyes, I'll have someone dig them out for you!

......

While the two were cultivating, Lin Fan heard Lin Xiaobai arrive.

He turned to look at the quiet grass.

How did you find me?

The two stopped training.

The grass rustled slightly.

Lin Xiaobai jumped out from inside.

"Of course, it's because I have a keen nose!" Lin Xiaobai jumped into Lin Fan's arms.

"Oh, it's her." Minato recognized Lin Xiaobai and continued training with the ball he had just bought.

"Her? Isn't that Lin Fan's pet?" Kakashi asked, puzzled.

"That's no ordinary pet." Minato shook his head.

Kakashi: "? So she's a ninja beast?"

Ninja beasts are summoning beasts that possess chakra.

"That's not it." Minato shook his head again.

Kakashi: "???"

Upon seeing this, Minato told Kakashi that Lin Xiaobai could understand human speech.

"Oh, that's it." Kakashi was speechless. He had thought Lin Xiaobai was some kind of hidden master.

While Lin Xiaobai was enjoying being petted in Lin Fan's arms, he suddenly felt a disdainful gaze directed at him.

Who is it?! Who is looking at this bunny?!

When Lin Xiaobai saw the direction of the gaze, her rabbit eyes widened.

It's you, Kakashi!

"Lin Fan, I challenge Kakashi!"

We must show Kakashi who the real genius is!

Lin Fan didn't seem to care. He patted Lin Xiaobai's head and said, "Are you sure? You can't beat him."

"It's okay, I'll call some reinforcements!" Lin Xiaobai shook his rabbit head. "I have to let Kakashi know that Lin Xiaobai and Lin Fan are the true geniuses of this world!"

Goodness, this little bunny is starting to care about his image; his intelligence is growing!

"Alright then." Lin Fan didn't refuse. He brought Lin Xiaobai to Kakashi: "Kakashi, Lin Xiaobai wants to challenge you. Do you accept?"

Kakashi, who was practicing with water balloons, slowly typed a question mark: "?"

What do you mean? Are you insulting me?

"I don't bully nameless little rabbits," Kakashi said coldly.

He also couldn't bear to tear the rabbit apart with his bare hands.

"Bold Kakashi! I'm the genius!" Lin Xiaobai purred in Lin Fan's arms.

"Lin Fan, you..." Minato stepped forward to advise, "Lin Fan, Kakashi may have some strength..."

Kakashi, who could hear it: "?"

"But Lin Xiaobai is just an ordinary rabbit..."

Kakashi nodded.

"If all else fails, I'm willing to help Lin Xiaobai get revenge."

Minato smiled.

Kakashi: "???"

"Need not!"

Lin Xiaobai jumped out of Lin Fan's arms and performed a set of Tai Chi in the snow.

"Let me see who the real genius is!"

Lin Xiaobai's mind flashed to a middle-aged man with white hair, red eyes, and wearing blue plate armor.

Heavenly Rank Technique: Possession by a Ghost!

......

"Here we go again." Tobirama Senju entered Lin Xiaobai's body once more.

"It's snowing?" Tobirama Senju noticed that the floor of the house had turned into snow, and curiously reached out his rabbit paw to touch it. Eh! It's cold!

"Moshi moshi! Can you hear me?"

Lin Xiaobai shouted at Tobirama Senju.

"What's going on? Why do I hear a woman's voice?"

Tobirama Senju looked around and then looked up to see only Kakashi and Minato, two figures that were as big as giants.

"It's me, Lin, Xiao, Bai. I'm the one who called you here. Help me defeat that white-haired Kakashi."

Tobirama Senju: "?"

She said she was the one who called me here...

and many more.

Tobirama Senju looked down at his palm.

Could it be that the owner of that voice is a rabbit?!

The rabbit's body malfunctioned, and Tobirama Senju was questioning the meaning of life.

"So, this is its strength?" Kakashi's lips twitched; he couldn't see what was so powerful about Lin Xiaobai.

"Don't underestimate her," Lin Fan said. "She possesses the most powerful fighting techniques in the world."

"A duel?" Kakashi didn't understand, shook his head, and thought to himself that Lin Fan was getting more and more ridiculous.

At this moment, Tobirama Senju communicated with Lin Xiaobai for a while.

Tobirama Senju: "You say this is your body, so how did you summon me? Was it through the Impure World Reincarnation?"

Lin Xiaobai: "What Impure World Reincarnation? Lin Fan said this is a Heaven-Rank technique called Ghost Possession! It's my unique fighting skill!"

Tobirama Senju: "? I don't understand. But who is Lin Fan?"

Lin Xiaobai: "The one behind me."

Tobirama Senju turned and glanced at Lin Fan.

Hmm, he's a young man who seems quite normal.

But why would this perfectly normal young man find a rabbit that knows strange ninjutsu?

Tobirama Senju couldn't understand it.

Since I can't figure it out, I'll stop thinking about it for now.

"I can help you," Tobirama Senju said, "but you must promise me that next time you summon me, you must take me to see Tsunade, the blonde woman who appeared in the house last time."

"Oh, that tigress? Okay, I promise you." Lin Xiaobai nodded.

It wasn't that she didn't want to use Tobirama Senju's power to fight, but rather that although she inherited one-tenth of Tobirama Senju's fighting strength, it didn't include combat experience, because Tobirama Senju's combat experience was that of a human, while she was a rabbit.

Tobirama Senju skillfully formed a hand seal with his rabbit paws: "Water Release: Water Wall!"

Sensing the chakra fluctuations, Lin Fan was the first to dodge.

Next is the water gate.

Kakashi was still rambling on when he looked down and noticed that a ring of water had appeared around Lin Xiaobai... Hmm? Is it forming hand seals?!

"Water Release: Water Shock Wave! Glug glug!!" The water around 'Lin Xiaobai' transformed into a water column.

Kakashi hadn't yet reacted to the fact that the rabbit had used ninjutsu by forming hand seals.

By the time he realized what was happening, the water jet had already hit his abdomen.

boom!!

Kakashi flew away.

"We won. This kid is really weak." 'Lin Xiaobai' spat. He, the Second Hokage, only managed to beat a weakling on his first appearance. If his older brother knew, he would probably laugh at him.

......

"Hey, are you alright?" Lin Fan appeared over to Kakashi and saw that Kakashi had been beaten to the point of vomiting blood, so he quickly used a hemostatic technique.

Kakashi felt like he had just almost seen his mother.

The mother transformed into Lin Fan's hateful face.

"...That counts as a sneak attack. Let's try again." Kakashi's first thought upon waking was still about winning or losing.

"...Are you sure?" Lin Fan's lips twitched.

"Maybe we should just forget about it," Minato said, running over to comfort him. "Losing to a rabbit isn't shameful."

"!!!"

Kakashi retorted, "That won't do!"

......

Fortunately, there was still time.

When Lin Xiaobai saw that the brat stand up and provoke him again, he couldn't bear it anymore.

"How dare you! No wonder you're a boy from Konoha."

If that's the case, then he won't perform as Tobirama Senju anymore.

Clasp your hands together!

Instantaneous movement technique!

The little rabbit used a Body Flicker Technique that Kakashi couldn't react to.

However, Kakashi still saw it the moment it appeared.

"I see you!" Kakashi threw a punch at the rabbit.

"Idiot." The rabbit formed a hand seal: "Darkness Travel Technique!"

He used his superhuman strength to block Kakashi's fist.

Kakashi's gaze vanished in an instant.

The sensation of a fist appeared for a moment and then disappeared.

"What kind of ninjutsu is this?!" Kakashi, unable to see anything, groped around like a blind man.

"Is this considered a loss?" The rabbit pointed at Kakashi and said to Lin Fan. He knew that Lin Fan was Lin Xiaobai's master.

Lin Fan imagined the scene of Kakashi breaking the genjutsu and then shouting "I refuse to accept this!"

"I reckon he's still not convinced," Lin Fan shook his head.

Minato: "..."

You...

Upon hearing this, the rabbit nodded, "Understood."

Tobirama Senju considered the ninjutsu he knew.

His main advantage is that most of his ninjutsu are highly lethal, which is necessary when dealing with the Uchiha clan.

"I choose you!"—"Water Release: Water Prison Technique!"

......

"Glug glug." Blind Kakashi suddenly choked on a mouthful of water that appeared all around him. Moreover, in this weather, the cold water was freezing cold, and Kakashi's eyes were rolling back.

A moment later, Tobirama Senju's soul emerged.

"It seems each time lasts about two and a half minutes." Tobirama Senju noted the time and said, "I don't know if you can hear me, but see you next time."

Lin Fan and Lin Xiaobai......

......

"He's gone." Lin Xiaobai ran wearily from the water dungeon toward Lin Fan.

The water prison has been opened, and Minato is giving Kakashi emergency treatment.

"Thank you for your hard work." Lin Fan patted Lin Xiaobai's head and put him in his coat. Lin Xiaobai closed his eyes contentedly and soon started snoring.

......

Lin Fan stepped forward and cast a hemostatic spell on Kakashi.

Kakashi suddenly woke up from his dream.

"That was terrifying. I just had a nightmare. I dreamt that I was defeated by a rabbit." Kakashi looked around but didn't see the rabbit, and then breathed a sigh of relief.

Minato and Lin Fan: "..."

Is it possible that this isn't a dream?
