Naruto: Rise to the top

When Tsunade saw Sayuri, she was fascinated by her attractive appearance, but she resisted the urge to go and hug her and went to Kushina's side and carried her.     

As soon as Kushina saw that Tsunade carried her, her body relaxed and then she fell asleep in Tsunade's arms, because she did a lot of training today and combined with her stress trying to catch Sayuri and she was very tired so she fell asleep quickly.     

Sayuri became worried when she saw that Kushina had fallen asleep, so Tsunade asked anxiously, "Is she okay? I was just joking with her, I didn't mean to hurt her."     

"Kushina's fine, just tired from training today. I'll take Kushina home to rest. Bye, Ryuu," Tsunade answered Sayuri's question.Then she said goodbye to Ryuu and walked home.     

"You made Kushina so tired, you shouldn't have done all this to her." Ryuu said to Sayuri seriously.     

"Don't look at me like that, I didn't force her to try to catch me, she's the one who did it herself." Sayuri spoke annoyed because Ryuu blamed her for it.     

It's true that she was worried about Kushina when she saw her sleep from tiredness in Tsunade's arms, and she felt a little guilty for what she did but when Hearing Ryuu blaming her, Sayuri's guilt faded away and was replaced by annoyance.     

"Whatever I want you to be on good terms with Kushina, that's it. Let's go home too, I'm tired."Ryuu sighed and started walking towards the house as Sayuri jumped on his shoulder and stood on him.     

When he arrived at the house, the lights were off and everyone was sleeping, so he quietly entered the house and went to his room to rest, but as soon as he reached the door of his room, Souta suddenly appeared behind him and spoke, which frightened Ryuu, "It's you, I thought there was a thief breaking into the house."     

"Before you ask yes I passed the test, I'm really tired I want to sleep so I'll talk about the details tomorrow." Ryuu turned his face towards Souta and said, then entered his room.     

...     

the next day. In the morning.     

Ryuu got up and stretched his body a little and noticed that Sayuri was sitting with her eyes closed and there was energy gathering around her.     

When Sayuri noticed that Ryuu had woken up, she opened her eyes and the energy gathered around her dispersed. She looked at Ryuu with bright eyes, "Finally you're awake, where are we going today? Are there fun places in your village to spend time in?"     

Although Ryuu couldn't see that energy, he could sense it. Ryuu looked at Sayuri and asked in astonishment, "What was the energy gathering around you a while ago?"     

"It's natural energy." Sayuri thought everyone knew about natural energy. So she was surprised when Ryuu asked her about it.     

"I know what a normal energy is, were you just training in Sage Mode?" Ryuu asked Sayuri.     

"It is an art that can be used in Sage Mode called Sage Art: body cultivation, but I will not tell you what this technique does because it is my clan's secret information."     

'I guess I saw this skill yesterday in the stats of the Sayuri. system , show me the information about this technique,' Ryuu thought, then asked the system to show the information about Sage Art: body cultivation.     

[Sage Art: body cultivation:     

is a technique used to extend life by combining natural energy with the Yang chakra and nourishing the cells of the body using it, to increase the life span of cells.     

flaws:     

It will take a lot of time from the user to extend his life sufficiently, which will reduce his training time on other techniques significantly.]     

'That's why even though Sayuri has a very great talent her strength is still at the level of a Kage (low). She must be focusing most of her time and attention on this technique, I wonder how powerful she would be if she didn't pay attention to this technique and focus on increasing her strength 'Ryuu thought once he saw the flaws in the technique.     

Nine-tailed foxes are often the same age as humans, but due to this technique, they have become much older.     

In fact, the Nine-Tails Fox Clan focuses most of their time and attention on this technique. Therefore, although their age has become longer, their strength is slowly increasing because they do not focus on increasing their strength, but most of their attention is on increasing life in order to achieve their dream of reaching the age of 1000 years mentioned in the legend.     

'This is the technique I've been looking for, if I tweak it a bit and make the natural energy and yang chakra nourish the vitality of the cells، I might have Hashirama's ability to regenerate, and it's possible that I can awaken the Eternal Mangekyou Sharingan or even awaken the Rinnegan, I must tell Sho to teach me this art 'Ryuu was happy with this technique so he decided to tell Sho that he wanted to learn it, because apparently Sayuri would refuse to teach him this art.     

"Ryuu, what have you been thinking about for so long?" Sayuri patted Ryuu's cheek with her palm to get him out of his thoughts.     

"Sayuri I want to go back to your clan to learn Sage Mode from your grandfather," Ryuu said seriously, he really wanted to learn Sage Mode quickly before the war started, if he learned Sage Mode he might increase his strength and reach Kage (low) level . He also wants to know if Sho would teach him Sage Art: body cultivation if he asked.     

"What, I don't want to go back, you can go on your own." she arrived in this world less than a day ago and haven't explored yet, but Ryuu suggests coming back, which makes Sayuri upset.     

Ryuu thought and then said, "Okay, but you will be with Tsunade and Kushina while I'm gone and you shouldn't leave the village."     

"Let's go have breakfast first," Ryuu said as he walked out of the room.     

When Ryuu and Sayuri came out of his room, Fuku saw them and said, "Good morning, Ryuu-chan. I've already made breakfast, and I made some for our cute little guest too."     

"Hi my name is Sayuri, thanks for making food for me too." Sayuri said she was glad they made food for her too.     

After introducing themselves, they went to breakfast, Sayuri ate more than half alone and was still hungry, which made the Ryuu family shocked that she ate so much for her small size, then Fuku went to the kitchen again to make more breakfast for them.     

During this period, Ryuu told them that he would go back to the Nine-Tails Fox Clan to learn Sage Mode there.     

Fuku prepared more food this time. After eating, Ryuu and Sayuri went to Mikoto's house. He introduced Sayuri to her and then they went to the seventh training ground.     

When they arrived at the Seventh Training Ground, Ryuu left Sayuri with Tsunade, Kushina, and Mikoto and used the Reverse Summoning technique to go to the Nine-Tailed Fox Clan.     

(Question: How long did it take Naruto to learn Sage Mode?)
