Time passed in a hurry, and in a blink of an eye, Tsunade and Naruto had been traveling to the ninja world for more than two years, and Tsunade's mood was getting better and better during this time. It seems that the two seeds in her heart that led her to grief have gradually disappeared.

Half a year ago, Shizune also went back to Konoha after meeting with Tsunade.

In the past two years or so, Naruto has cultivated the Mixed Yuan Jue to the middle of the first layer, and his cultivation has successfully reached the peak of the Transformation God Realm, and the space in his body has also reached the level of millions of square kilometers, which is larger than the current area of the Fire Country, in addition to plants, a large number of animals have been introduced, because of the existence of the Chaos Blue Lotus Lotus, and the sun, moon and stars have also initially evolved, which is still because Naruto deliberately suppressed the cultivation.

From the inheritance left by Pangu, the area of the small thousand world should reach at least 1.2 billion square kilometers, the middle thousand world is measured in hundreds of millions of square kilometers, and the large world is measured in hundreds of billions of square kilometers, and the large world is the level of the flood world. According to Naruto's calculations, the space in his body must reach the level of the small world, at least it is possible to cultivate to reach the Great Luo Golden Immortal, which is still the reason for the Chaos Blue Lotus Lotus. In comparison, the world of Naruto is really too small, and it can only be called a planet, not a world.

Naruto is also nine years old, three years before the start of the Hokage plot. For more than two years, under the suppression of Tsunade, Konoha withdrew the ninja who was chasing Naruto, and Naruto agreed to Tsunade's request, planning to take a walk like in the original book in three years, so as to exercise the mental instability caused by the rapid improvement of cultivation.

The Nine-Tails have been like a change of character for more than two years, where is there still the appearance of the nine-tailed demon fox in the original book, just looking at Naruto Chenchen's rising cultivation, it can't move forward by half a point, so it is distressed.

Sitting cross-legged at the top of the inn tonight, as usual, after absorbing the last shimmer of moonlight, Naruto opened his eyes and returned to his room in a flash.

As soon as he entered the door, he felt two familiar breaths hidden in his room, Naruto covered his forehead helplessly, "Hey, two stupid people, come out"

"...... Uproar"

The lights came on all of a sudden, and the whole room was filled with a warm atmosphere, and at a glance it was a birthday party dress. Naruto's eyes lit up for no apparent reason, and he remembered that today was his ninth birthday.

"Happy Birthday!"

"Happy Birthday!"

Naruto's ears rang with the blessings of Tsunade and the Nine-Tails, which made his eyes moisten a little, he had been in this world for a few years, but he didn't expect that the first person to celebrate his birthday was this man and a beast.

Naruto initially experienced the warmth he had never felt before, and his mood became more relaxed, and he looked at the large cake brought by the two pairs of paws of the Nine-Tails, his face was slightly weird.

Tsunade and the Nine-Tails didn't mention anything else during the whole process, just quietly accompanied Naruto to eat the whole cake.

It is worth mentioning that since the Nine-Tails followed Naruto, after eating a barbecue at the instigation of Tsunade, this guy wanted to eat a few bites of anything delicious when he saw it, and even formed a human-like routine, but the body of that fox could not be changed, which can be called the best in the tailed beast world.

As soon as the cake was finished, Naruto felt that something was not quite right with Tsunade today. Sure enough, after ten minutes, Tsunade's skin began to wrinkle and become a little dry, exactly the same as Tsunade after opening the Yin Seal in the original book.

"Huh...... Tsunade, what kind of situation are you" Nine-Tails, who was the first to speak, was startled by the scene in front of him. Even Naruto was stunned and waited for a response.

"I didn't ...... It's okay, I suddenly forgot one thing in the past few days" Tsunade, who reacted, had a dry face that was even more unsightly, and he couldn't care about it so much, so he quickly made a mark in his hand and pressed it on the floor, "Psychic Technique......"

A cloud of smoke burst open, and a humanoid slug appeared in front of Tsunade, "Tsunade-sama, what are your orders?"

"Quick, help me recover, there aren't enough chakras in the Yin Seal" Tsunade ignored Naruto's gaze and said to the slug in a hurry.

The Nine-Tails on the side understood something in combination with Naruto's ridicule at the beginning, and said with a frightened face: "Little ghost, is it like what you said at the beginning, Tsunade's body can't generate new cells because of the large number of cell divisions, so this slug needs this slug to provide chakra to maintain the body."

"What do you say?" Naruto tucked his purple-blue hair behind his ears, his crystal clear fingers rubbing his delicate cheeks, thinking about something on his face that made the whole world jealous, and replied disdainfully while thinking: "This is what I told you, your so-called chakra is too low-level, it is completely a practice of exchanging life for strength, you have seen how many ninjas can live to be fifty years old except for the Uzumaki clan"

"Hey! Little ghost, you must think of a way, I don't want to be like this one day" The nine-tailed beast was a little anxious.

"An-la, An-la, with me, you can't die" Naruto was amused by this guy's hellish expression, and he no longer struggled with anything in his heart, and faintly made up his mind, so he waved his hand to signal the slug who was transporting chakra to Tsunade and said, "Hey, that slug, you go down first, you don't need to transport chakra to her anymore, this method is like a drug, just maintain it for the time being." I have a solution myself"

"Oh?" Slug glanced at Naruto suspiciously, there was no lie in the determined eyes, the slight smile represented confidence, and the energy in this child's body was even bigger and terrifying than her main body Slug Immortal, Slug chose to believe, "Okay, I'll leave it to you"

Tsunade didn't speak, not knowing what he was thinking, but the way he looked at him was evasive, and he saw countless frustrations in it.

Naruto's fingers lightly pressed against the purple yin seal on Tsunade's eyebrows, and a wisp of incomparably pure innate aura was injected into it, and then his fingers left Tsunade. With Slug and Nine-Tails stunned, Tsunade's body returned to ruddy at a speed visible to the naked eye, and his skin was even more supple than ever.

"Huh? So pure natural energy," the slug's sweet voice conveyed surprise. "Since Tsunade-sama is fine, then I'll go back first, and if anything happens, please feel free to summon me"

"Okay, slug, goodbye" Naruto made an OK gesture.

"Okay, then Tsunade-sama please" The slug disappeared into the room with a pop, leaving only the voice that had not been broken lingering in the room, "Also, children, I'm not a slug, please call me a slug, or slug-sama"

"Cut, stinking fart," Nine-Tails snorted.

Naruto looked at Tsunade with a look of distraction, as if he had lost his life, and his white palm stroked Tsunade's face that had become rosy again, and said, "Okay, big beauty, isn't this a change back?" What is there to be sad about."

Naruto finally knew why Tsunade had only used the Yin Seal a few times in the original book, not that he wouldn't use it, but now it seems that he didn't dare to use it. After all, Tsunade's vitality was consumed too much in the ninja war.

"Will you look down on me?" Tsunade drooped his head and said in a low voice. Since following Naruto more than two years ago, she has been attracted to Naruto's elusive methods, and Naruto has always treated her with an adult-like attitude, which makes her feel like she is getting along with her peers.

Gradually, she tried to come out of the sad memories of the past, but every time she became like this, she felt like she was back to those terrible days. will always suffer from gains and losses in her complicated relationship with him before at this moment.

Naruto reached out and gently stroked Tsunade's cheek, let Hou help her curled up body, took her white jade hand and smiled, "Don't worry, I know everything you think in your heart, aren't you just afraid of becoming like that?" I can fix it."

The childish child's voice rang in Tsunade's ears, and Naruto had grown under her chest at this time, and maybe in a few years he would be about the same height as her. However, Tsunade's teeth clenched and biting his lower lip were still a little sad and pitiful.

"Come here, Nine-Tails, put your paw on my shoulder, I'm going to take you somewhere"

"Okay, little ghost"
