Konoha's Dark Harvest

Zuo Yun had been developing new ninjutsu all morning, and every time he was just a little short of succeeding.

"Hiss! It hurts!" A needle-like feeling came from his hand.

Zuo Yun looked down and found that his palms and arms were covered with scars. Even though his recovery was amazing, he could not keep up with the wear and tear of the experimental ninjutsu.

"Zao Yun, you are indeed here. The old man said that your mission has been completed. What about your hand?" Zuo Yun was observing the injury on his arm when Tsunade's voice suddenly came from behind.

"Sister Tsunade? It's okay, it's just over-training. It'll be fine in a while!" Turning around to find Tsunade, Zuo Yun immediately acted like there was no problem, not wanting him to worry.

"Show me!" Tsunade ignored him and took Zuo Yun's hand with a gloomy expression.

"Is this okay? You don't want your life! Even if you have strong recovery power, if you continue like this, your hand might become useless." Tsunade felt very distressed and immediately used Palm Senjutsu to treat him.

"Hehe! I believe Sister Tsunade can heal my hand!" Zuo Yun looked at the nervous Tsunade, touched the back of his head and smiled innocently.

"Hmph! From now on, no forced training is allowed without my permission!" Tsunade glared at him angrily.

"No! I'm almost ready to develop it!" Zuo Yun looked bitter.

"Development? Are you developing ninjutsu?" Tsunade looked surprised.

"That's right! Based on the Thunder Release Ninja Taijutsu, I have integrated my strange power to complete several close-range moves. I have been experimenting with long-distance moves just now." Zuo Yun nodded and explained.

Tsunade hesitated for a moment. She knew Zuo Yun's body very well. In fact, without her treatment, it would take at most half an hour for the injury to be fully recovered.

"I understand! From now on, you have to develop under my supervision. If I think it's not working, you will stop. Do you understand?" Putting down Zuo Yun's healed hand, Tsunade said seriously.

"Hi! Hi! I understand!" Zuo Yun shook his head helplessly in agreement.

For the next three days, Tsunade accompanied Sakumo in developing ninjutsu.

Kushina would also visit him from time to time and accompany him in training.

With Tsunade's treatment, Sauno can develop with more confidence. So far, he has developed armor that is full of thunder and lightning. Of course, it is only a thin layer, which is not at the level of Raikage.

There is also the Chidori reverse push, but because this move is beyond Sakumo's control, it is not very complete.

When using the Chidori, the thunder attribute will activate the whole body. Because the speed is too fast, the dynamic vision required is very high. At least it needs to be used a few times before you can get used to it and not aim crookedly.

"That's it for today! Come and wipe away the sweat!" Tsunade wiped the sweat from Zoun's face with a towel.

"Thank you, Sister Tsunade!" Zuo Yun stared at her face with a moved expression. Tsunade had been training with him these past few days, which made him very touched.

"You...don't get me wrong! I'm just fulfilling my obligations as a teacher!" Zuo Yun looked a little embarrassed, and Tsunade turned her head and explained arrogantly.

"Yes! I know~" Zuo Yun responded in a funny tone.

"Speaking of which, Sister Tsunade, you said last time that you wanted to develop a Yin seal. Recently, I have also been learning sealing techniques. Maybe I can help you!" It was Tsunade who always helped him, and Zuo Yun also wanted to repay Tsunade and let her compete. The original work developed the art of Baihao earlier.

"Sealing technique?" Tsunade was a little confused.

"That's right! Grandma Mito asked me to learn it!" Zuo Yun did not tell anyone about the Jinchuuriki.

"Indeed! I learned the Yin Seal from my grandma, which can only store chakra. I have always wanted to develop it further, but I have no clue!!" Tsunade nodded in approval.

"That's it! I understand!" Zuo Yun knew what he was thinking and began to think.

Looking at Sakumo who was deep in thought, Tsunade couldn't help but look forward to it. She fully agreed with Sakumo's idea of ​​developing ninjutsu. After all, the previous Chidori was at least an A-level ninjutsu in her eyes.

More importantly, this ninjutsu can actually be used without seals in Sakumo's hands. If this jutsu is given to the third generation, the seal technique may be derived and more people can learn it.

After all, no one can imitate Sauno and instantly condense thunder attribute chakra. Most people need to perform seals to use attribute ninjutsu, unless you can achieve the conductivity of the whole body like Sauno.

"I thought about it! General medical ninjutsu uses chakra to stimulate cell regeneration. If the Yin seal is released and the whole body is stimulated with chakra, the wound will definitely heal quickly. Maybe with the huge chakra, maybe it can Complete limb regeneration.

In addition, if the chakra in the seal is continuously used to micro-inject throughout the body, it can keep the cells in peak condition. Does this count as eternal youth? "Zuo Yun explained his guess carefully.

After hearing this, Tsunade looked solemn and thought carefully.

"Maybe it really works... I'll give it a try." Tsunade held her chest and thought for a while, then prepared to experiment.

She took out a kunai and made a cut on her arm, and blood flowed instantly.

Zuo Yun was a little heartbroken, and Tsunade could see his heart: "It's okay! Don't worry!"

"Yin seal? Solution!"

Tsunade unlocked the chakra stored between her eyebrows, tried to gather it into the wound, and then stimulated the cells to heal.

As Zuo Yun expected, the wound healed quickly.

"It really worked!!" Tsunade looked overjoyed, hugging Zuo Yun to her chest and spinning her around.

"Tsuna... Sister Tsunade! I... I can't breathe!" With a pair of huge noses wrapped around his nose, Zuo Yun could bite the soft flesh even when he spoke.

"Pfft! You little pervert!" Tsunade's face turned red and she immediately put him down. She was also bitten very itchy by Zuo Yun.

"What? It was obviously Tsunade-san who took the initiative..." Zuo Yun looked like he was getting an advantage and still behaved.

"Hmph! This is a reward for you!" Tsunade pinched Zuo Yun's face angrily.

"I'll try again and keep the weak chakra throughout my body." Her previous success made her eager to try.

"Unsolved!" This time Tsunade only unlocked the weak chakra stored in the Yin seal.

Zuo Yun looked at Tsunade's face, as well as her exposed arms and thighs, and found that they had become plump and delicate to the naked eye, making people unable to help but play with them.

"Snapped!"

That’s right!Zuo Yun also proved with practical actions that he is really tender!However, he was immediately slapped away by Tsunade who was blushing.

"Ahem! Let's see if it works..." Zuo Yun explained with a smile.

"I know it was successful without you coming!" Tsunade rolled her eyes coquettishly.

"It seems you are a little pervert! You really understand how to develop ninjutsu~" After flirting with Zuo Yun, Tsunade looked surprised. No woman can resist the temptation of eternal youth.

"No, no! I'm just thinking~ Mainly because Sister Tsunade has strong chakra control ability!" Zuo Yun was telling the truth. For ordinary people, it is impossible to maintain chakra throughout the body.

Only Tsunade, a medical master, can perform such terrifying micro-manipulation.

"Why don't we give these two techniques new names!" Zuo Yun suggested, looking at Tsunade who was still immersed in surprise.

"Hmm... Indeed, what do you think it should be called?" Tsunade nodded and threw the question to him. After all, it was Zuo Yun who proposed the idea, and Tsunade wanted him to name it.

"Then... releasing the chakra at full power is called [Yin Seal? Creation and Regeneration], and the continuous input of chakra is called [Hundred Heroes' Art]!" Zuo Yun thought about it for a while, and still said the original name. out.

"[Creation Regeneration] [Hundred Heroes' Technique]? Not bad! Not bad! Let's call it this from now on!" Tsunade nodded with satisfaction and found that the naming style was very to her liking.

Looking at Zuo Yun, she became more and more satisfied, which made her feel that Zuo Yun and her were connected.
