Naruto: I am immortal and can open the eight gates infinitely

"I just don't want to suddenly have an extra brother."

Senju Nawaki scratched his head awkwardly: "Chiba was born on August 8, just one day earlier than me, so I don't agree with you, sister, recognizing him as your brother."

Tsunade didn't expect that Senju Nawaki, who is the same age as Uchiha Chiba, still has such a childish side. Then she rolled her eyes and said:

"It's just one day. If you don't want to call Chiba brother, then don't call her. Kushina is one month older than you, why don't you call her sister?"

"Yes, it's you, sister, who recognizes Chiba as your brother, not me who recognizes him as my brother."

Senju Nawaki suddenly realized: "Can't we just call each other?"

Seeing this, Tsunade also breathed a sigh of relief. She didn't expect that the trouble of Nawaki was solved so easily.

Then she waved her hand: "Okay, since you have figured it out, then you go and talk to Chiba yourself. I'm sleepy and I'm going to sleep."

"No, sister, just help me with this. I really don't have the confidence to let Chiba come to our house."

Senju Nawaki then thought of something: "How about this, sister, as long as you can let Chiba come to our house, I will give you a massage for a week, how about it?"

"One month." Tsunade raised her finger.

"No, at most two weeks." Senju Nawaki shook her head.

"Anyway, my minimum requirement is one month. If you don't agree, then go and talk to it yourself. Okay, I'm sleepy, I'm going to go back to sleep."

"Wait, okay, just one month, but sister you must promise to call Chiba." Senju Nawaki gritted his teeth.

Tsunade walked out of the room and waved to Senju Nawaki with her back.

…………

Back to the present, after making this request, Tsunade looked at the boy in front of her who was taller than herself with a nervous face.

In fact, Tsunade also hoped that Uchiha Chiba would agree. After all, they were going to her house, so wouldn't she be able to eat the food he cooked?

"Sister Tsunade, how about you tell me the reason first? I'll decide whether to go or not then."

Uchiha Chiba didn't mind going to the Senju clan's land, just to cook a meal, but he still wanted to know why.

Hearing this, Tsunade hesitated for a while, after all, this matter involved Senju Nawaki, but after a moment, she figured it out.

Then she completely recounted Nawaki's revenge plan the night before and Uzumaki Mito's desire to taste his cooking.

Finally, she also told her the conditions that Senju Nawaki had asked her to agree to let him go to the Senju clan's land last night.

Although he betrayed Nawaki, isn't his brother meant to be betrayed?

Guilt, what guilt? Can that thing be eaten as a meal? Not to mention the meal cooked by Uchiha Chiba.

"Okay, Sister Tsunade, I agree. It's my honor that Lord Mito wants to eat my cooking, but it has to wait until next weekend. Sister Tsunade, you know that tomorrow is Monday, and I have to go to school."

After listening to Tsunade's retelling, Uchiha Chiba agreed without hesitation. After all, she is the grandmother of the child's mother, and they are all family.

Isn't it natural to cook a meal for the family?

As for Nawaki? That's easy to do. After going to school tomorrow, I will continue to beat him up in the name of sparring.

Thinking of this, he couldn't help but reveal a hidden smile at the corner of his mouth.

"You agreed to Chiba? That's great, it doesn't matter, it's just a week, it won't take long." Tsunade was very happy. Although it would take another week to eat the food made by Uchiha Chiba, wasn't it something to look forward to?

And Uchiha Chiba has come to her house, so can she go to Uchiha Chiba's house for a meal next time?

"Then I'll go back first, sister Tsunade. You can eat slowly."

"Well, you go back first." This time Tsunade didn't try to stop him.

After returning home, Uchiha Chiba suddenly thought of something.

He opened his hands and looked around. They were empty.

"Oh no, I forgot to bring back Tsunade's lunch box."

Then he thought about it and said with relief: "Forget it, it's just a lunch box."

…………

In the afternoon, by the river in the woods.

Uchiha Chiba stood by the river and looked at the river quietly. After a while, he shook his head:

"Forget it, let's start with climbing trees. It's not good to get your clothes wet."

Then he walked to a big tree, looked up, and then began to attach chakra to the soles of his feet.

He stepped on the tree trunk tentatively.

Hmm?

Didn't fall?

Uchiha Chiba looked at the sky, then turned his head to look at the ground.

I succeeded in one try?

Isn't this as hard as I imagined?

He was ready to be beaten to a pulp, but he didn't expectSuccessful on the first try.

"Let's try treading water again."

After coming down from the tree, Uchiha Chiba's confidence increased, but he was still a little worried about treading water.

"If I had known, I would have practiced in the bathtub at home first. If I failed, I would have to go home to change clothes."

Then Uchiha Chiba thought about it. Since he was here, wouldn't it be a waste of time if he went back without trying?

Then he repeated the previous operation again. After attaching the chakra to the soles of his feet, he stepped carefully on the river surface.

As expected, Uchiha Chiba succeeded again.

Looking at the reflection in the water, Uchiha Chiba felt it was quite interesting.

Although he successfully mastered the fine control of chakra, Uchiha Chiba was not very happy.

Because this was somewhat inconsistent with his plan.

His original plan was to let Tsunade accidentally discover that he was learning the Palm Immortal Technique, and then he could use this as an excuse to ask Tsunade for advice. In this way, the relationship between the two would definitely improve by leaps and bounds.

But now, it seems that his plan needs to be slightly changed.

The previous steps remain unchanged, and then he packages himself as an ordinary person with little talent in medical ninjutsu, and then plays a trick in front of Tsunade. Finally, under Tsunade's guidance, his medical ninjutsu improves by leaps and bounds.

Well, perfect.

Although Uchiha Chiba has only learned the refinement of chakra now, he has not started to learn Yang escape.

But to put it bluntly, Yang escape is nothing more than the embodiment of a person's vitality. For him who has used "overgrowth" to strengthen his body for several years.

Vitality is definitely not worse than Tsunade.

This plan is perfect. The only drawback may be that doing so will disappoint Uchiha Genka.

However, when he marries Tsunade home, I believe Uchiha Genka will be proud of him.

After all, he should be the first Uchiha to obtain the Senju since ancient times.

…………

The next day, lunch break.

On the school rooftop.

"Shengshu, do you want to do some after-meal exercise to digest it?"
