Reborn into Naruto World with Tenseigan

Kuroto had a thoughtful look while looking at the Water Curtain that splattered on the ground.

In the trial just now, Kuroto copied the exact Chakra movement as it was when Haku cast the Jutsu, from the direction of Chakra flow to the volume of Chakra used and ratio to be followed, all of them were kept exactly the same as Haku, and yet the result was a complete failure! ​​

'It seems that this approach wouldn't be the best method to learn Kekkei Genkai; even if it is present if the blood.' – thought Kuroto with his hand on his chin.

After all, if learning a Kekkei Genkai was so easy then their value wouldn't be so high!

Even if Ice Release is the result of a simple fusion of Water and Wind Chakra Nature, it would be far from as simple as it sounds.

It seems that the key point is not the Chakra flow mechanism, nor is it the perfect ratio but it is the perfect Nature fusion of Water and Wind Nature at the basic level.

While Kuroto was thinking and theorizing, Haku released the two Jutsu as he didn't have enough Chakra to maintain them any longer because of his young age.

But seeing that Kuroto-Sama was busy thinking something important, Haku didn't dare to disturb Kuroto and obediently stood at the side.

Even after storming out his brain to figure out a method, Kuroto couldn't think of any approach for a short while so he decided to use the next best option, turning towards Haku he asked, "Haku when you use Ice Release, do you feel anything different?"

"Uh… different!?" – Haku was a bit ignorant and couldn't understand what Kuroto was asking, what does it mean by some different feeling?

Understanding this, Kuroto changed his question, "Remember, what is the difference between Ice Release and Water Release when you use them? Anything out of the ordinary that you would say characterizes and differentiate the two styles!?"

After a bit of thinking, Haku replied, "Well there are indeed some differences, it's just that…"

Kuroto asked hurriedly, "Just what?"

Turning his head down downwards Haku spoke slowly, "It's just that… I can feel the differences, but I don't know how to word them…"

Kuroto patted Haku's hair and gently urged the kid, "Don't worry, think about it for a while and then speak… try to explain as clearly as possible, there's no hurry so take your time."

After calming down a little and thinking about it, Haku said, "I think that the biggest difference is that when I use Water Release, I only need to print the hand seals and guide Chakra flow and the ninjutsu would work, but when I use Ice Release, it doesn't work with only hand seals, I can't be distracted even a little bit or else the ninjutsu would fail." – After explaining this, Haku looked at Kuroto wondering if he was satisfied by the explanation.

Kuroto frowned slightly, 'So is it focus? Uh…, this doesn't help me at all! I am already putting all the focus I can… sigh, looks like I'll have to use that method!'

It is probably impossible for Haku to summarize the actual differences between the Ice Release and Water Release as of yet. Considering his young age and lack of in-depth understanding of various Natures, most likely it was his talent and emotional stimulation that led him to awaken the said Kekkei Genkai, but it looks like he hasn't yet grasped the essence of Ice Release!

So, now that Kuroto only has the last option which he didn't want to originally use, but it appears that is the only choice.

With that decision, he took Haku back to the Death Forest and said, "Haku wait here for a little while, and I will be using a technique so relax and don't resist, otherwise it could be a bit painful, understand?"

Haku promised, "U-understand!"

With Haku's nod, Kuroto immediately withdrew his soul from the clone-B body and transferred it back to the main body in the secret lab not far away.

Haku saw that the 'Kuroto-Sama' before him suddenly lowered his head and closed his eyes as if he went unconscious, as a result; he was surprised.

However, thinking of the previous instructions that Kuroto gave him, he didn't move from the spot where he was sitting nor did he attempted to disturb Kuroto-Sama who was probably using the technique he mentioned before.

Not long after, Kuroto in his main body rushed towards the spot where Haku and Water Clone-B body were sitting.

Since the 'Tenseigan Soul Transfer' instantly returns the soul to the main body, therefore he brought Haku near his secret laboratory so that he could rush here as soon as he can.

Hiding behind a tree not very far away, Kuroto stared at Haku who was looking around and glancing at the Clone body from time to time.

Activating the Tenseigan, Kuroto again used the 'Tenseigan Soul Descend' to transfer his soul, but the target this time wasn't the Clone body nor was it the puppet body, but it was Haku who sat in a cross-legged position on a small rock boulder in front of the Water Clone-B body.

As if affected by a Genjutsu, Haku suddenly felt very sleepy.

At this time, Kuroto's voice suddenly sounded in his mind, "Haku concentrate!"

He was shocked suddenly, and the sleepiness disappeared. Looking around in surprise, he checked the 'Kuroto-Sama' before him but it seemed as if he was still unconscious.

In a confusion, he asked in a low voice, "Ano, Kuroto-Sama, were you the one who spoke to me just now?"

"Yes, it was me, don't care about all this, now demonstrate an Ice Release technique to me…" – Kuroto urged eagerly. He didn't want to spend much time inside Haku, as this is the first time, he has transferred his soul inside an alive person, so maintaining will be a bit troublesome, besides it's not like he wants to take over the body control.

There is not much difference between the 'Tenseigan Soul Descend' and Orochimaru's 'Living Corpse Reincarnation,' both the abilities allow the user to transfer their soul to other vessels, although Tenseigan Soul Descend is much advanced in this field.

However, Kuroto knows that this technique also has its own flaws and repercussions, if the user tries to take control over the bodies of others' then a battle of the soul has to be conducted and the user has to devour the target vessel's soul, but here comes the problem, devouring other soul changes the soul signature of the user as well as damages it, which makes the soul unstable as is the case with Orochimaru in the main story.

Due to repeatedly transferring his soul from one vessel to another, his soul had actually become highly complicated that had decreased his spiritual power, therefore mental attacks like Genjutsu became his weakness.

In this case, Kuroto is very cautious to not do anything that would damage his soul, and this is one of the reasons he was hesitating to use Tenseigan Soul Descend to transfer his soul inside Haku's body, but now that he was left with no other option, so he chose to do it, but Kuroto is still very cautious and doesn't dare to have a spiritual battle with Haku's soul.

Kuroto understands that even if he can easily take over Haku's body, it is inevitable that there would be some small cracks that may appear on his soul which might expand over time.

That is why he only attached his soul to Haku's for a short while, and no doubt Haku would feel a huge burden because of this, his young body isn't suitable to bear the burden of Kuroto's soul, for this reason, Kuroto urged Haku eagerly because being attached for too long would most likely cause irreversible damage to both the parties.

Under Kuroto's urging, Haku took a deep breath to relieve the sudden heavy pressure he was feeling and quickly performed Ice Release Techniques.

Hand Signs printing.

Chakra Mobilization.

While simultaneously, he shouted, "Ice Release Secret Technique: Demonic Mirroring Ice Crystal!"

Whoosh!

However, even when everything was in order, by the time he completed the seal there was no change in the surrounding except for the light breeze that blew by the side, blowing away the scattered leaves in a roundabout curl.

Haku was confused, "Huh…!?"

Even Kuroto who was attached to Haku was at a loss and asked, "What happened?"

Listening to Kuroto's question, Haku replied hurriedly, "I… I don't k-know what's going on, it was clear before, it… it should have worked like always…"

Kuroto thought a little about the possible cause and said, "Don't use Demonic Crystals, try using simple ninjutsu with low chakra cost!"

After a short nod, Haku again printed the hand seals and shouted, "Ice Release: Ice Mirror!"

This time finally the ninjutsu didn't fail and a transparent Ice Mirror appeared in front of Haku instantly.

Because Kuroto's soul is attached to Haku's body while he performed the technique, Kuroto also had a clear feeling as if he has himself performed the Ice Release Jutsu.

This kind of personally experiencing the entire casting process of the Jutsu is undoubtedly the best learning method.

After experiencing this, Kuroto again ordered Haku to perform other Ice Release Techniques to gain more understanding of the Kekkei Genkai.

And when he was satisfied, he decisively pulled back his soul to the main body.

The moment Kuroto was back to his own body Haku lost consciousness, and Kuroto separated a Shadow Clone to send him back to the underground residence and himself returned to the secret laboratory with the Water Clone-B body.

Kuroto was confident that now that he has personally experienced the entire casting process of the Ice Release, it wouldn't take him much time or effort to learn Ice Release Kekkei Genkai…
