I am Naruto, I sacrifice Asura at the beginning

The ring thing is really a big blind spot. Uzumaki Naruto only remembered about the wedding and the ring when he was reminded.

But the ring is not something that needs to be purchased specifically.

Diamond itself is just a substance produced by pressing carbon element to the limit.

Diamonds themselves are very cheap, but they are just very hard and beautiful-looking stones.

If there hadn't been a strange advertisement that increased the existence value of diamonds, then diamonds would actually be the kind of stone that no one would care about even if it fell on the ground.

Therefore, Uzumaki Naruto can actually prepare things like diamonds.

There is no need to just do it in front of Tsunade, it would be better to wait until it is done before giving it to her.

"……"

The two of them just sat like this, unable to talk as casually as they did in the past.

「What should I say now?"

Uzumaki Naruto really doesn't know how to find a suitable topic with the opposite sex. He has no experience in this area.

「Idiot, won't your stinky brother find a chance to get close to his sister?"

Seeing that this bratty brother didn't make any movement at all, Senju Tsunade couldn't help but feel a little anxious.

Senju Tsunade, who really couldn't wait any longer, looked at her stinky brother sitting opposite with her eyes.

"Then what?"

"Then...what?"

"Fool! Of course you have to say something!"

Tsunade Senju confirmed at this moment that this stinky brother is definitely the kind of person who doesn't know how to interact with women.

"I said to you, you just proposed, shouldn’t you say or do something to the person you propose to?"

"……Ah, how's your research going?"

"As for that, it has actually developed to a pretty good level."

When it comes to research, Senju Tsunade subconsciously shifted her attention. After all, there has been some progress in the recent research on the soul. This is the foundation for future immortality.

"The souls of the dead do have corresponding death marks. The souls with that mark will be attracted to the Pure Land and will not be able to stay in this world at all."

"Therefore, according to your previous speculation, eternal life is the gray area between life and death."

"Since the soul can obtain the characteristics of eternity without using special methods, it can connect the soul on the basis of the body, so that the soul and the body can be synchronized, and further enjoy the common immortality of the soul and the body."

Research in this area is also the conclusion reached at this stage.

Regarding this conclusion, Senju Tsunade also made it clear that immortality of body and soul is indeed something that can be achieved, but the method requires further research to obtain it.

"Orochimaru's physical condition has also been verified."

"That idiot snatched another person's body without devouring the other person's soul. The little remaining soul caused his own soul to bear too much burden."

"To solve this problem, we need to completely eliminate those souls that have not been devoured, and we also need to find ways to repair our own souls."

Repair is the most serious problem. The most troublesome thing for Senju Tsunade is actually the repair of the soul. This is an area that needs to be explored. They are also crossing the river by feeling the stones and are still exploring the way forward.

Uzumaki Naruto also knows that it is very difficult to repair the soul, at least without knowing the method. Compared with repair, destruction is relatively simple.

"Then start from the direction of chakra"

"Chakra is also the most direct connection between this world and the Pure Land. The issue of soul repair can also be considered from the perspective of Chakra."

"Chakra?"

Tsunade Senju thought for a moment and nodded.

"I know, and next I will tell Grandpa Er and Orochimaru to research in the direction of chakra."

The next important research direction is still the soul.

Helping Orochimaru solve the problems in the soul will also be of certain help to the study of immortality. After all, immortality has a certain relationship with the soul. Now it is definitely not necessary to know more about the mysteries of the soul. It would be wrong.

But when she said this, Senju Tsunade suddenly stopped and looked at Naruto, this stinky brother, with a speechless expression.

"Then, if I ask you to talk, you will talk to me directly about research topics?"

"Well, actually I don’t know what kind of topic I should talk to you about."

Well, Senju Tsunade is also helpless. It's too difficult for this stinky brother in this regard. It's actually not suitable for her.

There is no way. In fact, she herself doesn't know what topics she can have with this stinky brother at this time. Let’s talk.

Tsunade Senju stood up from the cushion, moved the table in the center away, and stood in front of her stinky brother.

"Feet, spread apart, I want to sit"

"oh."

Uzumaki Naruto slightly spread his legs that were sitting cross-legged, and Senju Tsunade sat directly on it, leaning back directly.

This"seat" became stiff, and Senju Tsunade clearly felt it.

"Hands, holding me from behind."

Uzumaki Naruto was a little stiff now, but he still listened to Tsunade's words and hugged Tsunade from behind.

「Not very heavy, about fifty kilograms."

Perhaps it is a habit. When Uzumaki Naruto is upset, he will subconsciously analyze and pay more attention to the current situation in more detail, and roughly estimate Tsunade's weight.

It’s not particularly heavy, and is even a pretty good weight for a well-figured mature woman.

Because he was holding Tsunade from behind, Uzumaki Naruto could feel that Tsunade's waist was also quite slender, and he didn't feel any fat at all.

Senju Tsunade, who was sitting in the arms of her stinky brother, looked proud. She could feel his stinky brother's discomfort and stiffness in his body, which was undoubtedly a confirmation of her charm.

「Huh~ Smelly brother, you know the charm of your sister."

She doesn't mind these simple contacts, not to mention that she has already agreed to the proposal. Is she afraid of some simple contacts?"

If she's scared now, won't she be scared to death on the wedding day?

"Hmm~"

Stretching out comfortably, Senju Tsunade leaned directly into her stinky brother's arms.

"My recent research has made me very tired. I came back early today because my mental state is really unbearable."

"So hard?"

"Yes~ Research is very easy for us to get started, and once it officially starts, it is difficult to stop in the middle."

Once you start research, the enthusiasm for research that is unconsciously ignited will explode uncontrollably.

"I'm not the only one who's burning, Grandpa Er and Orochimaru are also the same"

"This research topic is much more interesting than imagined"

"You also know that my second grandfather just likes to study those forbidden arts, and he is also very interested in the study of the soul."

"So after this research started, we began to put all our efforts into it."

But even if she burns with astonishing enthusiasm, Senju Tsunade must admit that after a period of rest, she cannot allow too little rest time, or even directly choose not to rest, otherwise her mental state will not be maintained.
