In Konoha: Eating Goro Goro no Mi at start.

"Don't you want to go on a trip with me?"

As soon as they went out, Tsunade let go of Rei.

She didn't even look at Rei. She just lowered her head and walked forward beside Rei, looking at her toes dejectedly.

I was clearly trying to get a vacation for myself and Rei today.

But Rei was siding with Senju Tobirama, which made Tsunade feel a little betrayed.

She couldn't help but wonder if Rei didn't want to go out traveling with her, or if Rei didn't like her anymore.

"Yes, of course I do."

Rei turned his head and looked at Tsunade who was sulking on the side. He stopped and pulled Tsunade to face him.

"But there are always some things that need to be done first, right?"

Rei placed a hand on Tsunade's head and stroked her hair.

"Master Tobirama is already very old this year, and his time may not be long. If we can develop a permanent senjutsu before Master Tobirama leaves this world, then Master Tobirama will be able to accompany Tsunade longer?"

After a pause, Rei continued to speak to Tsunade.

"Who wants that old guy to keep me company?"

Tsunade immediately turned her head away in disdain and spoke angrily, but the confidence in her tone was obviously insufficient.

"So, can we put the travel on hold and develop the permanent Sage mode first?"

Seeing this, Rei couldn't help but laugh and asked Tsunade softly.

"Okay, so after we develop it, can we go out and play?"

Tsunade had to admit that Rei was right.

However, it is impossible to admit my mistakes, I will never admit my mistakes in this lifetime.

"That shouldn't be possible. If we are lucky enough to develop Senjutsu in a short period of time, we should also develop Wood Release and Magnet Release as soon as possible."

Rei chuckled at this, and spoke to Tsunade as if what happened just now had never happened.

In fact, when two people live together, some conflicts are inevitable. At this time, the most important thing to do is not to distinguish right from wrong, but to solve the problem.

"Ah~ Are you in such a hurry?"

Tsunade wailed when she heard this, hugged Rei right arm with both hands, and looked at Rei in front of her pitifully.

"Yes, because I feel that the war may be about to begin." Rei sighed helplessly and said to Tsunade.

"War? I think I am definitely vey powerful!"

Tsunade immediately spoke to Rei.

As for what Rei said about the war that was about to break out, there was no doubt about it at all.

Because Tsunade also felt that the war was about to begin.

This is something that almost anyone with a little political acumen can see.

"That's impressive, but does Tsunade want to go through a war every once in a while?"

Rei raised his eyebrows when he heard this and asked Tsunade.

"Huh? Do I lose to you every time because I don't want to win?"

Tsunade was stunned when she heard that, and looked at Rei in front of her as if he was an idiot.

"So, I think, war, once is enough."

Rei raised his eyebrows when he heard this and said to Tsunade.

"Does Rei have any ideas?"

A gleam of light suddenly appeared in Tsunade's eyes.

Whether in the Warring States Period or the Hidden Village Era, peace is always the subject that ninjas have been looking for the answer to.

"Why do you think there is a war, Tsunade?"

Upon hearing this, Rei did not answer Tsunade's question, but asked Tsunade back.

"Because of profit?"

Tsunade frowned and thought after hearing this, and asked Rei after a moment.

"Yes, but there is another reason besides profit." Rei chuckled at this and said to Tsunade.

"What?" Tsunade blinked when she heard that and asked Banyue.

Tsunade has always believed that the origin of war is profit. Does Rei have any other answers?

"Have you ever thought about why there has never been a large-scale war in the ninja world when the first Hokage was alive?"

Upon hearing this, Rei did not answer but asked instead.

"You mean... the cost of starting a war?"

Tsunade's eyes suddenly lit up with realization when she heard this, and she asked Rei.

"So, hurry up and become stronger. In the war that may happen in the near future, make the Hidden Village that started the war pay a price they cannot afford."

Rei nodded upon hearing this and said to Tsunade.

"Okay! Then let's practice hard starting tomorrow!"

Upon hearing this, Tsunade nodded vigorously and said to Rei.

"Hmm~"

Upon hearing this, Rei nodded with satisfaction.

But then he reacted 'Tommorow'

Before he could react Tsunade pulled him in cabinet.

It's not that Tsunade is bold but living together in Shikkotsu forest for so long and had done everything except that.

Tsunade wanted to do it during travel bit since she can't go for a trip she will change the time.

At night two of them did some kidney practice where Tdunade won die to bloodline of Senju clan.

Next Day at noon

"You guys are finally here! I thought you guys went to another place to practice."

Jiraiya said as he looked at Rei and Tsunade who were walking towards him holding hands.

"Eh? Rei, what have you been doing these days? Why do you look so unhappy? Are you practicing secretly by yourself?"

Before Rei could say anything, Jiraiya asked Banyue with a suspicious look on his face.

Rei: "…"

"Jiraiya, has the nature change of your earth chakra been completed?"

Just at this moment, Orochimaru came over wiping his sweat with a towel.

"It will be done soon."

Jiraiya said with a hint of excitement in his tone that after completing the change in the nature of the earth escape chakra, he would have mastered the changes in the nature of three types of chakra.

"So what are you waiting for?"

Orochimaru tilted his head slightly upon hearing this and spoke to Jiraiya.

"I know, I know, Orochimaru, why are you suddenly so long-winded?"

Jiraiya said to Orochimaru impatiently after hearing this.

"Do you want to rest for a while?"

Orochimaru glanced at Rei, hesitated for a moment, and finally asked.

"No need." Rei chuckled upon hearing this and said to Orochimaru.

"Um."

Orochimaru nodded, turned around and left. His intuition told him that Rei should have no desire to communicate now.

"Today, let's develop magnet release and do some recovery training instead of high-intensity physical training."

Tsunade whispered to Rei.

After thinking for a while, Tsunade continued to speak to Rei.

"I'm sorry. I didn't expect this would affect your practice."

But there is no way, Rei is really great...

I can't help it, I can't help it at all...

"It's really okay. I understand my physical condition."

Rei said with a bit of a smile upon hearing this.

It is the kidneys that are tired at night, and it is the liver that is tired during the day.

Although very tired, but it does not have much impact.

He found a place to sit down, and a spherical piece of metal appeared in Rei's hand and was placed in front of him.

He stretched out his right hand, stopped about ten centimeters away from the metal ball, and began to practice Magnet release.

The practice method is roughly the same as practicing the changes in the properties of chakras.

Rei has already completely mastered electricity. The next step is to master magnetism. Then Rei will have mastered the electromagnetic force, one of the four fundamental forces of the universe.

…

Tsunade sat next to Banyue.

This is the change in the nature of earth jutsu chakra and water jutsu chakra.

The fusion of the two attributes is the Wood Release that was once famous in the ninja world.

But at the moment, it is very difficult for Tsunade to do this.

It's really difficult.

…

When Orochimaru saw the two people sitting on the ground practicing, a hint of envy flashed in his eyes.

It's not a bad thing to feel difficulties, because as long as you solve the problem, you will be promoted.

Unlike me, my wind escape technique has been cultivated to the extreme and it is basically difficult to improve it further.

This is not a good thing for Orochimaru. After all, as of now, Orochimaru has only caught up with Rei in one item.

"Rei, Tsunade, Hokage-sama asks you to come over."

The ANBU figure appeared at the third training ground and spoke to Rei and Tsunade.

Upon hearing this, Rei and Tsunade stood up, looked at each other, and followed the Anbu away.

"Tsk! When will the Anbu say something like, 'Jiraiya! Did the Hokage-sama ask you to come over?'"

Jiraiya said with some envy as he looked at this scene.

"Huh? Just based on your level of Sage mode alone, yoi are not worthy?"

Orochimaru glanced at Jiraiya and said casually after hearing this.

"That's better than a guy like you who doesn't know any Sage mode, right?!"
