Naruto: The Medical Ninja

Chapter 212: Chapter 209: Replicate Kekkei Genkai

Dan thought, ”There is no way....”

His eyes widened slightly, a look of amazement and disbelief crossing his features.

Ryu explained the purpose and function of the seals he had created. ”One of them fuses two different chakra natures in a fifty-fifty ratio, and the other does it in a twenty-eighty ratio.”

Dan’s breath hitched in his throat. He asked, ”That explosion before...?”

Ryu replied, ”That was a fifty-fifty fusion of earth and lightning chakra, and it resulted in an explosion release!”

Dan’s eyes widened in surprise. ”Explosion Release? that stone village’s Kekkei Genkai?”

Ryu nodded eagerly. ”Yes. And did you feel a strange pull before the power blackout?”

Dan was shocked, thinking, ”Don’t tell me.”

Ryu replied, ”That was from a fusion of wind and lightning chakra. It seems I can replicate the effects of Magnet Release too!”

Dan was stunned at Ryu’s statement.

Dan stared at Ryu, his face a mixture of astonishment and apprehension.

Dan said, ”Magnet Release and Explosion Release? Ryu, do you realise what this means?”

Ryu nodded, his excitement slightly tempered by the gravity of his discovery. ”I think so, Grandpa. The seal has the potential to replicate Kekkei Genkai.”

Dan shook his head slowly and said, ”Ryu, you cannot talk about this to anyone. The situation is far more dangerous than anything you have done so far.”

”I understand, Grandpa,” Ryu replied solemnly.

Dan leaned forward, his voice low and urgent. ”This kind of ability... it makes bloodline abilities almost obsolete. If the world finds out that there are fuinjutsu seals that can grant Kekkei Genkai to just anyone, there will be a war just to get their hands on this knowledge. Trust me on this, Ryu.”

Dan then asked, ”If you can achieve Explosion and Magnet Release, have you considered what other combinations might be possible? If you trained in water affinity, could you, for instance, mix water and earth to replicate the effects of Wood Release?”

Dan wanted to know if Ryu had thought about the potential of combining different elemental abilities to create new, unique Kekkei Genkai. He was curious to see how far Ryu’s abilities could be pushed.

Ryu replied thoughtfully, ”If my guess is right, Grandpa, then the seal tag itself might act like a seed. When activated with the right chakra mix, it could potentially grow into a tree right where it lands. The size of the tree would likely depend on the amount of chakra used, and the effectiveness in a particular area might vary based on the ratio of chakras. Wet regions might need more earth chakra, while drier regions would need more water chakra.”

Dan nodded thoughtfully and said, ”What you’re saying is logical. But did you even realise the gravity of the situation?”

Dan continued to explain, ”The most visible superiority the Fire Nation has over others is because of all the fertile lands this nation has. And all this fertile land was extended to far-reaching ends of the nation because of the Wood Release of the 1st Hokage. During his peak, he grew forests everywhere he went.”

Ryu already understood the significance of this discovery, but Dan was overly impressed.

Dan then told him sternly, ”Do not conduct any further experiments with these seals without my presence, Ryu. Promise me. The consequences of any leaks about your activities could be catastrophic, potentially leading to widespread destruction or endangerment. Other ninja villages may try to kill us even in the safety of the village, even if it means risking a war.”

Ryu reassured him, ”Yes, Grandpa. I made sure Kaori was not present during yesterday’s experiments. Furthermore, I reinforced the privacy seals around the lab and added extra security measures.”

Dan said, ”It was a wise choice to keep your secretary out of the loop. I still don’t trust her completely. There’s something about her behaviour that raises suspicions.”

Ryu stated confidently, ”I trust her, Grandpa.”

Dan asked, ”What makes you so sure, Ryu?”

Ryu leaned in slightly and confided, ”She’s a secret ANBU, Grandpa. The Third Hokage assigned her to watch over me.”

Dan’s eyes widened in surprise. ”A secret ANBU? How did you find that out?”

Ryu replied with a knowing smile, ”You know my methods, Grandpa. Nothing escapes my observation for long. My keen eye for detail and subtle cues often reveals hidden truths.”

Dan said, ”If Hiruzen has placed her there for your safety, then I suppose it’s acceptable. But if I even get the slightest feeling that she’s here to spy on you for other reasons, I will speak to Hiruzen directly.”

Ryu calmed him down, saying, ”Don’t worry, Grandpa. It’s fine. Besides, once you know who a spy is, they’re no longer a spy. They become a rat.”

Dan then mentioned, ”The barrier seals you have around the lab are still low-ranked. I’ll place some higher-ranked ones later today, just to be safe.”

Ryu thought to himself, ”Great! Another opportunity to study advanced barrier seals.”

Ryu said, ”Alright, Grandpa. I should probably head to the academy now.”

Ryu attended his classes at the academy as usual and returned home. Later that day, Ryu trained in the second stage of the Senju-style taijutsu in the garden.

He was in no hurry, as his overclocking time was already exhausted. He decided to continue his taijutsu training and would tinker with his new seals later. He noted with satisfaction that he could now break the earth pillars in just two punches.

Ryu thought, ”Just a bit more, and then I can do it in just one hit. Maybe I should try to up the level and try harder elements. Ryu then had an excellent idea. He was already working on a substance as hard as steel – the carbon fibre. He still was far away in the carbon control to generate such substance at his will, but he could still make it in his lab.

Ryu thought, ”I am going to make a dummy made of the carbon fibre to take impulse release to the next level.”

Ryu’s chakra veins are already denser than normal. If he could increase the impulse output, Ryu theorised that this way his chakra veins would have more density than even the Senju clan’s elites. Even if he cannot break the carbon fibre dummy, he will keep on marginally raising the intensity of the chakra impulse each day.

Ryu thought, ”But I had to be careful not to hurt myself irreversibly.”

Ryu was also mindful of avoiding chakra nerve damage, as a gradual increase in chakra impulse was essential to allow his body time to adapt and prevent irreversible harm.

Ryu thought, ”Okay, once I can break the stone pillar with just one punch 10 times in a row, I will go for the stone pillar. Then I will then go for carbon fibre, and I will raise the intensity very carefully and slowly.”

The next morning Dan and Ryu were ready. Ryu mixed different ratios of chakra and tested the seal with a wind-lightning combination and a lightning-earth combination of chakra. He discovered different ratios have different reactions. He now knows many different ratio combinations for many different intensities of magnetic effects and explosive effects, from weak to strong. Magnetic variants have varying effects, but explosive effects were mostly similar effects with slight changes. He memorised each ratio and its effects for future application.

He created a few seals using the variant of the seal and tested them.

- [High Power Explosion Seal]: A variant of the Chakra-Fusion seal that stores earth and lightning chakra in the seal in a 50-50 ratio and fuses them together upon triggering to imitate [Explosion Release-Kekkei Genkai]. This seal, when placed on a target (earth formation, object, or even potentially a restrained person), unleashes an extremely powerful explosion upon activation.

- [Wide-Area Explosion Seal]: A variant of the Chakra-Fusion seal that stores earth and lightning chakra in the seal in an 80-20 ratio and fuses them together upon triggering to imitate [Explosion Release-Kekkei Genkai]. Once placed on an area of earth, upon triggering, the explosive chakra sweeps into the earth, surrounding a vast area depending on the amount of chakra. Simultaneously, the stored chakra in the earth explodes, creating a cluster of wide-area small explosions.

- [Landmine Seal]: A variant of the Chakra-Fusion seal that stores earth and lightning chakra in the seal in a 20-80 ratio and fuses them together upon triggering to imitate [Explosion Release-Kekkei Genkai]. When placed on the ground or another surface, this seal is dormant until pressure, contact, or a chakra signature activates it. Upon triggering, the stored earth and lightning chakra combine to create a powerful, localised upward explosion with lightning-augmented shrapnel of earth directly at the seal’s location.

Ryu now had explosive seals that would put the explosive crop of Stone Village to shame. Mostly, they were not stable unless he toned down the intensity by using less chakra, but the [Landmine Seal] was mostly stable. Ryu tried more combinations, but they showed similar effects to other explosive seals.

A/N:

Hey everyone,

So sorry for my month-long absence! Personal commitments ended up taking over, and sometimes, those just have to come first. I’m back now and really hoping to get back to regular posting.

It’s still a bit of a juggle balancing work, my personal life, and writing. If I find myself needing to make a tough choice, rather than just disappearing again, I’d prefer to lower the Chapter frequency to three per week—just like when I started this story. And if I do that, I’ll also reduce my patron subscription fee proportionally. I believe in being fair, even if it means less money for me.

I’m really hoping it doesn’t come to that point, but I wanted to give you all a heads-up. My studies, work, and personal life are all incredibly important, and I can’t compromise on them. I truly hope you’ll understand if I need to make that adjustment.

Get ready for another Chapter in just a few hours! And please keep those Power Stones coming!
