Under Konoha’s Shadow

Chapter 33: Kekkei Genkai

Hashirama and Tobirama had actually arrived much earlier, but seeing the children discussing ninjutsu, they didn't want to interrupt them. Who would have thought that they would actually invent such an incredible ninjutsu?

"Ryusei is just one step away from finishing it. To achieve the effect of the Rotation just now, you need to change the single-direction rotation of the chakra into a chaotic, multi-directional rotation, concentrating the power into a single point. Like this." Tobirama opened his hand and condensed a Rasengan, then pressed it against the rock. The rock was instantly blasted with a large hole three meters deep and one meter wide.

The corner of Yamamoto Ryusei's eye twitched incessantly. As expected of the inventor of forbidden jutsu, Tobirama Senju. With a simple gesture, he figured out the principle of the Rasengan and even showed off a bit, leaving me with no opportunity to look cool.

Tobirama continued, "This jutsu has another very advantageous point: it doesn't require hand seals. Therefore, it can be cast very quickly. It can be used against ninjas with strong defenses, such as Earth Style users."

Hashirama looked at the hole made by Tobirama's Rasengan and said, "The power of this ninjutsu is probably at the B-rank level. Considering it doesn't require hand seals, it can be considered an A-rank ninjutsu. Ryusei, you should give a name to the jutsu you invented."

Ryusei glanced at Tobirama and said, "This jutsu was completed by Teacher Tobirama. It should be Teacher Tobirama who names it."

Tobirama said in a faint tone, "The core of the jutsu was proposed by you, and you would have figured out the last step eventually. Of course, it's considered your ninjutsu."

Ryusei smiled happily. "Then let's call it the Rasengan."

Tobirama nodded. "That's a good name."

After praising the children, Hashirama and Tobirama left.

Uchiha Kagami and the others let out a huge sigh of relief. Ryusei, no longer needing to pretend, directly condensed a final-form Rasengan the size of an egg.

"It's so beautiful," Komiya Yuki remarked, looking at the pale blue Rasengan.

"Don't be fooled by its beauty; its power is also immense," Ryusei said, pressing the Rasengan against the rock. Instantly, a hole appeared.

Ryusei sensed the chakra he had just used and said, "The chakra consumption of the Rasengan is a bit high. It's not very suitable for us to use right now."

Kagami said, "That's right. After all, there's not much difference between killing someone with a kunai and killing them with a Rasengan."

Ryusei thought for a moment. "I'll write down the training method for the Rasengan for you all later, so you don't have to bother experimenting anymore."

Sarutobi Hiruzen said with some hesitation, "Is that really okay? You invented it, after all."

Ryusei smiled. "It's fine. Without you all, I wouldn't have been able to invent this jutsu. Besides, ninjutsu can only advance through communication. Sticking to old conventions won't work."

"That's right," Inuzuka Rō said, winking and teasing, "The Rotation has been in the Hyuga clan for so many years and was only a defensive ninjutsu. But in Ryusei's hands, it's become a powerful offensive technique."

Hyuga Natsuki's face darkened a little, but he couldn't refute it. Who could he blame but the Hyuga clan for not thinking of it for so many years?

Kagami also lamented, "Yes, ninjas nowadays hold onto their secret techniques so tightly. It's so difficult to have an honest exchange."

"After all, there are too many enemies. If you don't protect your own ninjutsu and the enemy finds out, you won't even know how you died," Ryusei said after some serious consideration. "How about we just exchange ideas more often in the future? For now, let's not exchange other clan ninjutsu."

Everyone nodded in agreement.

Hiruzen thought for a moment. "What do you all think about Kekkei Genkai? I heard that things like Ice Release and Explosion Release are synthesized from chakra."

Kagami said slowly, "That's right. For example, Ice Release is a fusion of Water and Wind Release chakra. Explosion Release is a fusion of Earth and Lightning Release."

Natsuki also said, "Fusing a Kekkei Genkai is very difficult. To become a first-generation Kekkei Genkai user, you first have to train two chakra natures to their highest level of transformation before you can attempt to fuse them."

Inuzuka Rō yawned. "Why think about all this? We're not qualified to research these things right now. We should just focus on mastering our own family's jutsu first."

Ryusei retorted, "You can't say that. If we prepare now, we can start experimenting directly when the conditions are right in the future."

Kagami said, "Then let's find some non-secret materials from our families and discuss them together."

Ryusei nodded. "Then let's set the location at my house. Since I'm the only one living there right now, anyway."

Hiruzen said with a lecherous grin, "Yuki can live with you."

Hearing this, Yuki's face instantly turned red. The thought of living at the Yamamoto house wasn't so bad.

Kagami said, "Then it's settled. We'll meet at Ryusei's house after school tomorrow."

Ryusei wrote down his insights on training the Rasengan at the Senju compound, gave everyone a copy, and then they all went their separate ways.

After eating dinner at home, Yuki and Ryusei went out for a walk, hand in hand, as he walked her home. They unconsciously found their way to the riverbank where they used to practice.

Yuki said to Ryusei, "Look, Ryusei, that's where we used to fish. When I think about the three of us fishing together, I feel so nostalgic."

Ryusei smiled. "It's only been a few months. If you want to go fishing in the future, we can come here."

Yuki shook her head. "No need. I know you're eager to train. Let's forget about fishing."

Ryusei thought for a moment. "Yuki, I know I spend less time with you, but this ninja world isn't safe. If a war breaks out, I'll have to go to the battlefield. It's better to sweat more now and bleed less in wartime."

Yuki said with surprise, "The battlefield? Isn't it peaceful now?"

Ryusei stroked Yuki's soft, long hair. "Peace isn't so easily achieved. The great nations are only wary of Teacher Hashirama and Teacher Madara for now. The moment something happens to either of them, it will be the prelude to war."

Yuki was silent for a long time before saying, "Ryusei, when I confessed to you, I said I would train with you. Being able to train together every day now... I think that's wonderful."

Ryusei hugged Yuki. "I'm sorry, Yuki. When my strength is such that I fear no one, then I can rest."

"Mm..." Yuki replied, secretly resolving to keep up with Ryusei's pace.

Under the moonlight, Ryusei walked Yuki home. At her door, he kissed her forehead again, causing the peeping Komiya Yuta to burn with rage.

Seeing the blushing Yuki return, Ayako said, "Yuki, you should bring Ryusei back for us to have a proper look at him someday. Your father can't see him clearly through the crack in the door."

Hearing this, Yuki's face turned beet red. "I'll bring him for you to see on my next birthday."

Ayako was a bit speechless. "But that's a whole year away."

"That's right," Yuki said slyly. "If you're not at home then, you won't get to see him."

Komiya Yuta said with guilt, "Yuki, we had urgent business this year, that's why we broke our promise. We'll definitely celebrate your birthday with you next year."

Yuki said happily, "Really? Then I'll invite Ryusei and a lot of other classmates to come."

Yuta said with the tone of a new-money tycoon, "It doesn't matter how many people you invite! Your dad has plenty of money!"

"Thank you, Dad!"

Looking at his daughter's cute, smiling face, then remembering her being kissed just now, the feeling of his precious cabbage being eaten by a pig deepened several more shades.

When Ryusei returned home, he found the lights on. Overjoyed, he pushed open the door and saw Yamamoto Shuichi and Yamamoto Nami sitting in the living room.

"Mom! Dad! You're back!" Ryusei said with a pleasant surprise. "Have you eaten? If not, I'll cook for you."

Nami looked Ryusei over. "We've already eaten. Ryusei, you've grown a lot taller lately."

Ryusei looked at his parents and saw that they were thinner than when they had left, but they also had more spirit.

He said happily, "It's been so long, of course I've grown taller. But you two have gotten much thinner. Is your work finished?"

Shuichi said with some helplessness, "No. The buildings are mostly finished. We came back this time to bring the staff over there. We can only rest for three days. By the way, Ryusei, are the chefs and managers all trained?"

The restaurant's chefs were all from the Senju clan, while the staff were clansmen from various families who couldn't become ninja or had little talent. They were all being taught by Liu Maoxing in the Senju compound. Once the restaurants were built, they would be sent to the various cities.

Ryusei nodded. "Liu Maoxing goes to the Senju compound every day. They're all trained now. I guarantee their skills are first-class."

Shuichi nodded. "That's good. It's getting late. We'll go take a bath and sleep first."
