Ninja Ice House

Whether it's a summoned beast or something else, we need to separate it first.

"So, you also want to use the 'Snake Shedding Technique' to cultivate it to a certain extent before cutting it off and signing a bloodline spiritual contract?"

"Is it not allowed?"

"It's not that it's impossible, it's just..."

Karin had never experienced anything like this before, so she really had no experience. But... she had made a boast to her father, Kosugi Bokumizu, not long ago, and then turned around and went back to ask her parents for help when she encountered difficulties. Wasn't that a bit too pathetic?

Moreover, according to his father, Gushan Bushui, the forbidden technique of "snake shedding" was not foolproof.

Ultimately, it comes down to the fact that most of the extraordinary beings in the ancient ninja world did not know where to hide their bloodlines; and the "Snake Shedding Technique" has a very strong effect of activating hidden information, which can easily trigger a very serious "atavism" mutation if one is not careful.

For example, Jiraiya has shown strong aptitude for Toad Sage training, with a significant improvement in his comprehension of Sage Techniques and a much stronger adaptability than before; while Usami has shown some abnormalities in his eyes and pineal gland, greatly enhancing his perception of chakra, and even with his eyes closed, his prediction of energy flow is much more accurate than before.

Essentially, this is a forbidden technique that relies on luck. If it activates a mutation that has a beneficial effect, that's fine. But if it increases the expression of some unsuitable or even harmful recessive genes, then it's troublesome.

For example, during the formation of the mermaid army, there were extremely high-risk mutants with abnormally developed venom glands, even risking poisoning themselves. It took a great deal of effort to save them and stabilize them.

As for the hoped-for success of replicating Hanzo the Salamander, that's definitely impossible. Such a miracle might not be replicated even once in tens of thousands of experiments. However, in the development direction of the mermaid force, there is an additional extremely dangerous "Venomous Guardian," which can only be used in extremely harsh environments and requires extra caution to avoid harming one's own people.

If Yakumo Kurama were to use the forbidden technique "Snake Shedding Technique," it might be beneficial, but there's also a small chance it could significantly stimulate the activity of the "monster" within him, accelerating the process of Yakumo Kurama being corrupted.

"Oh dear, the way you're all looking at me, you don't think I've gone crazy, that my thought process has been changed, do you? No, not at all..."

Karin and Usami were a little worried, but Kurama Yakumo was quite relaxed and reassured her two teammates.

"As a ninja specializing in manipulating mental and soul techniques, I am most wary of being eroded and subverted from the inside out. In my regular 'self-examinations,' almost all abnormal thoughts are thoroughly examined, their source traced, and it is determined whether they originate from my subconscious choices. If even this hurdle is overcome, then there is no need to stop me..."

"I hope there won't be any problems!"

Karin, still somewhat worried, offered her advice.

"Let my father take a look. He has high expectations for this technique, and he should be very interested in this strange change."

"Not for now, Karin! The young commander should already know something, but he hasn't intervened personally, which means it's still under control and there shouldn't be any major problems..."

"Alright! If you feel unwell, you must tell me. Even if... I have to beg my father to cure you."

"Cure? I'm not sick. At most, I'm taking some risks and trying to control my own development. I hope that after getting through this ordeal, my physical condition will improve significantly, at least so that it won't become my biggest weakness."

In fact, Karin was still a little confused. Logically speaking, Kurama Yakumo had obvious signs of "yin dominance and yang deficiency" in his body, but his father, Kosugi Bokusui, did not try to balance yin and yang. Instead, to a certain extent, he made the gap between yin and yang power even greater.

When the little girl asked this question, Yakumo Kurama smiled and replied:

"My father already asked me this question when I underwent my first physical adjustment to mitigate the risks brought by Idu. The young commander's answer was that the contrast between the yin and yang attributes within me was too strong, exceeding the limit of forcibly 'complementing' them with external force. He said that we needed to adopt some more radical, but more effective, methods to quickly improve the situation..."

For example, in the originally weak body of Kurama Yakumo, the proportions of Yin and Yang attributes were 100 and 1 respectively, which is 100 in comparison; but if the former increases to 150 and the latter increases to 20, the comparison becomes 7.5; if the former increases to 1,000 and the latter increases to 250, the comparison becomes 4.

The yin-yang balance within a ninja's body is not determined by the quantity of yin and yang, but by how unequal the balance is between the two ends.

When the Yang attribute power reaches 10,000, the Yin attribute power is only 18,000, reducing the ratio to 1.8. This value is out of danger and can be considered relatively safe.

After Kurama Yakumo's explanation, Karin and Usami roughly understood Furusugi Shōdō's view on Kurama Yakumo's unique physical characteristics.

Because of the existence of the bloodline limit and the risk of Ido's resurgence, it is actually not suitable to suppress the spiritual power within Kurama Yakumo's body. On the contrary, it should be appropriately strengthened to avoid imposing self-restriction, which would make the spiritual power with nowhere to be released even more restless, which would be undesirable. While strengthening the Yin attribute power, the Yang attribute power should be increased simultaneously. As long as the increase ratio is not too large, once the absolute base is large enough, the difference will be large, but the comparison between the two will be significantly more balanced.

"That's true. Yin and Yang attributes are difficult to 'go solo' for long periods of time. As long as your physical condition has largely recovered and you've refined your chakra to significantly increase your load-bearing capacity, a little more or less Yin attribute power isn't a big problem. In fact, the consumption of Yin Release is much greater when casting genjutsu or mental techniques..."

When practicing and using certain special ninjutsu, it is necessary to deliberately create a dynamic imbalance within the body in order to enhance the power of the ninjutsu.

For example, the Ino-Shika-Cho trio, Inuzuka, Aburame, and Uchiha clans, when using clan secret techniques or bloodline limits, have an imbalance of Yin and Yang. Otherwise, they would not be able to perform Yin and Yang chakra nature transformation and form transformation techniques.

Naturally, the Kurama clan's genjutsu-type bloodline limit requires extremely powerful Yin attribute chakra nature transformation and form transformation to achieve. However, Kurama Yakumo's innate disparity was too great, which had the opposite effect, suppressing his physical growth and causing a series of side effects.

“Since it’s Father’s decision, then it should be fine. Yakumo, show me your moves again, and I’ll check them out.”
