I, the stepfather of the ninja world!

After a few seconds, the door opened and Tsunade welcomed him inside.

Kushina was sitting on the couch in the living room, concentrating on reading Jiraiya's book "The Legend of Perseverance".

She was wearing a yellow dress, her red hair was draped over her shoulders, and she had a plump figure with round curves.

Seeing Kimura coming in, she raised a smile, her long legs pulled her plump hips, supporting her round pregnant belly, she slowly stood up and took light steps.

This posture has a bit of the calmness of a pregnant woman and some of the meaning of being a mother.

As the distance between him and her got closer, the seal on Kimura's abdomen became hotter and hotter. Combined with the hot sensation from Tsunade, he suddenly felt a burning sensation.

"What a rare guest! The last time we met was when you moved into the barrier!" Kushina giggled, her tone light.

As soon as she opened her mouth, her composure was instantly broken, and she was still as lively and outgoing as before.

Kimura smiled and said, "I have been training hard recently, trying to improve my strength so that I can protect you when you give birth."

"Don't be too stressed! There are five of us, and the opponent has a pair of Mangekyō Sharingan. They can't beat us!" Kushina smiled and patted Kimura's shoulder, looking like a big sister.

Tsunade coughed lightly and said, "You still have to be careful. If the opponent's pupil power is strong enough, he can control the Nine-Tails. If the Nine-Tails breaks the seal while you are weak, you will be dead!"

"Hehe!" Kushina scratched her head and smiled awkwardly.

Tsunade turned her head to look at Kimura and asked, "What's the matter with you coming here today?"

"Uh……"

Kimura was slightly stunned. From Tsunade's words, he could tell that the master had forgotten the weekly training class. Or, the master subconsciously thought that now was a special period and the training class could be postponed.

Kimura suddenly had an idea and decided to "forget" his training, skip the class, cherish the precious time, and go to the basement to happily knock on pebbles.

"It's okay, I just came to visit a pregnant woman and show basic humanitarian care." Kimura made up an excuse to cover up his sudden visit.

"Now, the visit is over. The pregnant woman is in good condition. It's time for me to leave."

After saying that, Kimura turned around and left neatly.

Hearing his strange words, Tsunade could not help but frown and narrow her beautiful eyes. Her mind flashed with thoughts and she blurted out: "Wait a minute!"

Kimura's heart skipped a beat and he stopped obediently.

"I suddenly remembered that today is Monday and I should guide you in training!" Tsunade said lightly.

"..."

After failing to skip class, Kimura sighed secretly, turned around and said with a smile: "Master, you have to take care of Kushina, so you probably can't spare the time."

"It's still possible for a while."

Tsunade said, looking at Kushina and instructed, "If you feel unwell, let the slug notify me. I can reverse summon back at any time."

Kushina smiled and responded, "Don't worry, I'll be fine!"

Tsunade nodded, and without further ado, she left the room, saying, "Ono, follow me."

"Bye!" Kushina smiled and waved to Kimura.

"Bye-Bye."

Kimura waved his hand and went out and upstairs.

In order to avoid being cramped and dark without sunlight, the rooms in the cave are designed to be very spacious and have a height of more than ten meters.

Therefore, the staircase is also very long, with nearly a hundred steps.

Kimura followed Tsunade up the stairs step by step. In this position, his eyes naturally fell on Tsunade.

Tsunade had long legs and fair calves. She wore the standard black low-heeled sandals of the ninja school, with thin black leather belts tied around her fair ankles. Her heels were white with a hint of rosy red, without a trace of callus, and were as smooth as jade.

With each step she took, white and black left graceful shadows in the air, creating a beautiful picture; the low heels of her sandals fell on the stone steps, making a cool sound that echoed in the cave, forming an elegant melody...

Volume 069 I really want to improve! : Does Master think I'm handsome too?

Tsunade is now nearly forty years old. She is not young, but she has mastered the art of maintaining her youthful appearance. She is still an extremely beautiful woman and does not look old at all.

Kimura followed behind her, smelling the faint and elegant fragrance that came from her nose, which made his heart flutter. He lowered his head and stared at her legs and feet intently, following her steps mechanically.

Suddenly, Tsunade stopped.

Kimura was not paying attention and did not stop, bumping into him and getting stuck in his arms.

Tsunade subconsciously exclaimed, frowned and turned around immediately, glared at Kimura, and asked: "What do you want to do?"

Kimura came back to his senses, quickly took two steps back, raised his hands to show his innocence, and explained: "I was distracted just now and didn't notice that you stopped, Master."

Tsunade raised her eyebrows and sneered, "Are you blaming me for not notifying you to stop in advance?"

Then, she pointed to the oval green stone door at the side and said, "Look where this is! We are already in front of the door!"

"It's my fault, my fault! I won't do it again next time!" Kimura admitted his mistake and begged for forgiveness with a wry smile.

Tsunade snorted and said nothing more.

Although she appears to be a bit harsh towards Kimura, she actually cares for him and loves him very much.

It was precisely because of this condescension due to age and status that she had no defenses against Kimura and did not think that he had any bad intentions.

At this moment, she rolled her eyes at Kimura, as if to expose the truth. Then, she turned around, grabbed the door handle, and pulled the stone door sideways open.

"Go in, you go in front this time." Tsunade said lightly.

"Yes, Master."

Kimura responded obediently and walked into the house.

Tsunade followed him in, closed the door, sat down on the stone chair beside the table, and looked at Kimura.

"You only became a ninja when you were eighteen, so there are many things you haven't learned yet. Therefore, in the past few months, I have focused on shaping your ninja basics to help you lay a solid foundation."

"Now, you are already an excellent ninja, and your control over chakra is also very good."

"And my technique has always required extremely high levels of chakra control."

"Now, I'm going to teach you my most important skill - the Yin Seal!"

Tsunade said, pointing to the blue and purple diamond shaped mark on her forehead.

Yin Seal, S-level medical sealing technique.

The sign of mastering this technique is the appearance of a diamond-shaped mark on the forehead.

After unlocking this technique and releasing a large amount of chakra, you can further use the [Ninja Technique·Creation Regeneration·Hundred Healings Technique].

"Ono, don't underestimate my technique just because you know the healing technique without seals." Tsunade emphasized seriously.

"How could I underestimate you?" Kimura looked innocent.

The price of kryptonian life for the sealless healing of the wedge seal is too high. In comparison, the Hundred Healings Technique consumes much less life, just shortening the life span a little, and there is no need to worry about being possessed by Kaguya.

I just don't know, after using the Hundred Healings Technique, can its treatment priority override the passively triggered Sealless Healing?

Kimura had no answer, but still wanted to learn this technique very much, because it is always good to have many skills!

Tsunade was very pleased with his modest attitude, and continued, "The Yin Seal can make extremely subtle adjustments and controls to the chakra, thereby achieving many effects such as accelerated healing, stronger attacks, faster movement, youthful appearance, and improved body functions..."

"Ono, once you learn the Yin Seal, you will naturally master medical ninjutsu and strange physical skills, and you will be able to keep your handsome face without any wrinkles."

"Master, do you think I'm handsome too?" Kimura asked with a smile, his eyes twinkling.

Tsunade frowned immediately and scolded: "I'm teaching you so seriously, and you just heard such idle words?"

"..."

Kimura was disappointed and kept silent.

Tsunade snorted coldly and said calmly: "Your master is not blind, of course I can see that you are outstanding in appearance!"

Kimura immediately grinned and said, "Thank you for the compliment, Master!"

Tsunade rolled her eyes at him and went on to get down to business: "It's hard to explain the key points of practicing the Yin Seal in just a few words. When I was practicing before, I summarized some of my experiences and took notes."

Notes?

This is the reference book!

Kimura's eyes suddenly lit up, and he stared at Tsunade's face intently, his eyes revealing a strong desire of "I want to see".

Tsunade shook her head and laughed: "The notebook is in the village. I will go back and get it for you now. However, I have left it in my study for many years. I don't know where it has ended up. It will probably take me some time to find it. Please be patient and wait for a while."

"Then let me go with you, Master. Otherwise it will be boring to sit here alone." Kimura said.

"as you like."

Tsunade said this, and then a cloud of white smoke burst out, and she returned to her home in the village through reverse summoning.

Kimura then emitted a cloud of white smoke.

In a blink of an eye, the master and disciple were standing in the living room on the first floor.

"The study is upstairs."

With that, Tsunade headed straight for the stairs, with Kimura following closely behind.

Before going up the stairs, Tsunade suddenly stopped and turned around.

Kimura was startled and stopped immediately, not understanding what she was going to do.

"Well done! You've learned your lesson by not bumping into me again." Tsunade praised softly, then turned around and walked upstairs.

"..."

Kimura opened his mouth, had nothing to say, and followed him upstairs silently.

After entering the study, Tsunade began to look for her notes. Kimura chose a place where she would not be in the way and sat down, watching silently.

Because she had to be on guard against sneak attacks from the Uchiha descendants inside the barrier at all times, Tsunade usually wore a light ninja uniform with soft armor covering her chest and abdomen.

At this moment, she was facing away from Kimura, bending down and looking through her notebooks in front of the bookshelf. This posture slightly tightened her loose uniform, making her look a little more graceful.

The sunlight shone through the window, fell on her body, and cast a charming shadow.

Kimura had nothing to do, so he simply held his chin and let his eyes move with the light and shadows.

For a moment, the study fell into silence, with only the creaking of bookshelves and the rustling of rummaging. The sunlight exuded warm warmth, outlining moving memories.

After an unknown amount of time, Tsunade, who was busy looking for her notes, suddenly remembered that there was a person named Kimura in the room, but she couldn't hear any sound. She turned around and found that Kimura was in a daze.

Tsunade couldn't help but angrily said, "Ono, you followed me back just to sit there and watch Master work?!"

Kimura was shocked back to his senses and asked innocently, "What else?"

"Don't you know to help me look for it?!" Tsunade was so angry that she laughed.

Kimura hesitated and said, "These are all your personal belongings, Master. It's not appropriate for me to rummage through them."

Tsunade didn't waste time talking to him, turned around and continued to look for her notes, and only said, "The notebook with [Yin Seal] written on the cover is my experience!"

Kimura raised an eyebrow, stood up obediently, walked to Tsunade's side, and looked for notes together.

……

Volume 070 I want to improve so much! : How dare you, evil disciple, hug your master!

Tsunade's study is huge.

She is the best medical ninja in the ninja world, and she has countless books on medicine, filling up shelf after shelf.

Because of this, trying to find the cultivation experience of the [Yin Seal] now is like fishing for stones in the ocean, which is by no means an easy task.

The master and disciple were very busy.

Stack after stack of books were pulled out from the bookshelf and opened to check the title pages.

Then, stack after stack of books were put back on the bookshelf and put neatly in order.

The wooden bookshelf had been around for a long time and had aged a lot. Suddenly, it was overwhelmed by such a heavy workload and kept squeaking, as if wailing for mercy.

The master and disciple showed no mercy at all and continued squatting on the ground, absorbed in searching for the [Yin Seal] notes.

The sun shone through the window into the room. The master and the apprentice were so close that their shadows on the ground almost overlapped.

Time passes silently, a faint fragrance floats in the air, and the shadow moves diagonally bit by bit.

Unconsciously, Kimura had finished flipping through another stack of books, wiped his sweat, looked up at the dozen or so bookshelves that almost reached the ceiling, and couldn't help but sigh, saying with emotion: "Master, I feel like we're going to have to spend the afternoon here."
