After completing the task of eliminating Yomi's cult, Kuroto immediately returned to Konoha and directly sneaked into his laboratory.
Now that the Ryuumyaku has been extracted from his body and sealed into the portable Gourd artifact, Kuroto no longer has to worry about the risk of Ryuumyaku going on a rampage while he uses the Tenseigan Soul Descend.
Coming to the laboratory, Kuroto looked at the Kazekage puppet who was standing beside him and thought a little.
'The security of the laboratory cannot be compromised, no matter what!'
This laboratory hides most of Kuroto's secrets, and he must ensure that its safety isn't affected. Therefore, Kuroto must see that the Kazekage Puppet remains active even when Kuroto uses the Soul Descend.
After all, once he uses the Tenseigan Soul Descend to transfer his soul from the main body to the Clone body, the Tenseigan itself will become inactive so Kuroto wouldn't be able to regularly transfer the Tenseigan Chakra to the Kazekage puppet which is required for its working and functioning.
So, after thinking a little, he decided to use another method and that is to seal a large volume of Tenseigan Chakra inside the Kazekage puppet.
This method isn't that uncommon in the Shinobi world.
Just before their death, Yondaime-Sama and his wife Uzumaki Kushina sealed all their remaining Chakra inside the body of their child Uzumaki Naruto, so that they could help Naruto tide over the difficulties in the times of crisis.
And Orochimaru also uses the Curse Seal technique to store his Chakra inside other shinobi as a backhand to ensure his resurrection.
Therefore, Kuroto can also use a Chakra Sealing method to ensure the continuous functioning of the Kazekage puppet.
Being a full-fledged activist, once Kuroto has an idea, he immediately tries it.
With that decision, he turned towards the Kazekage puppet and pressed his right hand on the puppet's chest area, and immediately a huge volume of Tenseigan Chakra flowed along with his right hand and transferred into the Kazekage Puppet.
Instantly, a bluish gleam appeared around the puppet's body.
When the amount of Chakra transferred was more than enough, Kuroto immediately performed the sealing technique.
"The Four-Symbols Seal: Seal!"
With the completion of the sealing technique, a series of black symbols spread around the chest of the Kazekage puppet and quickly contracted into a small size Four-Symbols Seal Technique's symbol on the chest.
When Kuroto was done, he casually asked the puppet while monitoring its state, "So, how do you feel?"
After a short pause, Kazekage Puppet felt it and replied, "Kuroto-Sama, with this amount of Chakra; if I don't partake in any battle, then the continuous functioning will last for about three months give or take."
Kuroto nodded in satisfaction.
Although a period of three months is not very long, it is still more than enough.
As for how long the sealed Chakra will last if the Puppet were to participate in a battle is hard to say, as different amount of chakra is consumed against different opponents, so no one can make an accurate estimation.
And that's not very important for now.
After dealing with this issue, Kuroto immediately used the 'Tenseigan Soul Descend Technique' to transfer his soul into the Clone-A body.
After putting on his clothes, and adjusting the Ryuumyaku Gourd, along with all the necessary tools and his Kusanagi Sword around his waist, Kuroto left the laboratory in his water Clone body.
At its current state, the Clone-A body is obviously far from being perfect to be ready for being used in the Chimera Technique as per Kuroto's standards.
Firstly, he has to let this clone 'which is just an accumulation of the fusion of his and Haku's cells' to adapt to his soul to achieve a Yin-Yang balance between the strength of Soul and Body.
This step is crucial!
If Kuroto doesn't do this, then there wouldn't be any essential difference between the Chimera Technique he plans to use and the one Hiruko plans to.
Secondly, Kuroto has to further cultivate the Water Clone to increase its strength, so that its strength is around the same level as his main body.
The reason for doing this is to have the same Chakra intensity of all seven natures to achieve a perfect balance when fusing them through the Chimera Technique.
Now, this is obviously very difficult because the Water Clone doesn't have the Tenseigan or anything that would help him reach the level as a Super Kage, but meh… there's no harm in trying, anyway, he has a lot of time in his hands, Kuroto will eventually find out some method to compensate.
Only in this way will he be able to reach a perfect balance of seven natures, to reach 'Kekkei Mora.'
Walking out of the Secret Laboratory, Kuroto applied a simple Transformation Technique upon himself to change the color of Clone-A's Black hair into brown; to avoid dealing with unnecessary troubles and came to the Underground residence where Haku was living temporarily.
Seeing Kuroto's arrival, Haku let go of the little rabbit from his hands to the ground and quickly greeted Kuroto, "Kuroto-Sama!"
Kuroto nodded towards Haku and asked, "Are you somewhat used to living here?"
The little rabbit that Haku was playing with was actually a test subject that Kuroto didn't use, and after he met OkinaButa he didn't need to use it anymore.
Initially, he kept it to use it as food, but because Yui loves rabbits very much, so this one was left alive.
Just to make sure that Haku doesn't get bored all the time while he lived in the underground residence, Kuroto decided to bring the little guy here as a playmate for Haku.
Now a rabbit as a playmate may sound strange, but it's still better over nothing.
Haku nodded repeatedly towards Kuroto's question.
With initial greetings out of the way, Kuroto spoke, "Alright, if that's so then it's good, now put Maron in her cage and follow me."
After giving this order, Kuroto turned and left the underground residence.
Haku also put Maron in her cage and quickly followed behind Kuroto and asked curiously, "Kuroto-Sama, are we going to practice ninjutsu?"
The corner of Kuroto's lips curved and he spoke, "Yes!" While he thought silently to himself, 'Unfortunately Haku, you won't, I will be practicing ninjutsu with your help!'
A short while later, Kuroto and Haku came near a lake at the lower reaches of the Naka River, far from the village, and way out of the patrol range, a safe place to practice ninjutsu and not attract unwanted attention.
Coming by the lakeside, Kuroto looked at the sparkling lake water with some emotions, he was reminded of some of his past.
Sighing lightly to not think about it, for now. Kuroto turned towards Haku and spoke, "Haku, at Orochimaru-Sama's place, you must have learned some Water Release Techniques, right?"
Haku nodded ignorantly.
With that confirmation, Kuroto pointed towards the lake and said, "Currently we are near a water body, so you can practice all those ninjutsu to higher proficiency, therefore show me all the Water Release Techniques that you have mastered!"
Haku was a little doubtful, the last time Kuroto ordered him to practice Ice Release Techniques, but how come today he suddenly ordered for him to show Water release Technique?
However, even if the kid was doubtful, he didn't dare refuse or question Kuroto's orders, Haku is still somewhat afraid of Kuroto because of witnessing the battle with Orochimaru.
So, nodding as per Kuroto's orders, Haku walked towards the lake and started printing hand seals to use Water release techniques.
Tiger – Ox – Tiger – Rat: "Water Release: Water Bullet Technique!"
As soon as he finished printing, a large amount of Chakra kneaded in Haku's stomach and he expelled a large quantity of water from his mouth in the form of a torrent towards the lake.
"Hm, a Class-C ninjutsu…" – after a nod, he added, "Continue!"
With Kuroto's order, Haku again started printing hand seals to perform other water-release ninjutsu.
Dragon – Tiger – Hare: "Water Release: Wild Water Wave!"
Dragon – Tiger – Hare: "Water Release: Water Trumpet!"
Ox – Monkey – Hare – Rat – Boar – Bird – Ox – Horse – Bird – Rat – Tiger – Dog – Tiger – Snake – Ox – Ram – Snake – Boar – Ram – Rat – Yang Water – Monkey – Bird – Dragon – Bird – Ox – Horse – Ram – Tiger – Snake – Rat – Monkey – Hare – Boar – Dragon – Ram – Rat – Ox – Monkey – Bird – Yang Water – Rat – Boar – Bird: "Water Release: Water Dragon Bullet Technique!"
'Hooh, Nidaime-Sama's Jutsu?' – thought Kuroto in surprise.
"Water Gun Technique!"
"Water release: Rising Water Slicer!"
After performing five Water Style Jutsu one-after-another even with the help of a water source nearby, Haku was already out of breath.
Kuroto observed him and asked, "Do you know any other Water Release Techniques?"
Haku replied lightly while trying to catch his breath, "I… I can still use the Waterfall Technique, but I don't have enough Chakra left."
"Waterfall Technique!?" – Kuroto was slightly taken aback and asked, "Waterfall Technique is the reduced version of the Great Waterfall Technique, you learned it at such a young age?"
When asked this question, Haku lowered his head and replied, "At Orochimaru-Sama's place… I…if I can't learn ninjutsu, I don't get to have dinner."
Kuroto just smiled at Haku's reply and didn't say much.
This isn't strange or anything new, even Anko-Chan had to suffer from such punishments back when they were training under Orochimaru, thankfully Kuroto was a researcher and had to practice the Hyuga Style Taijutsu, therefore, he wasn't subject to such punishments, but that wasn't the case with Anko, who would repeatedly complain and bad mouth Orochimaru whenever she would meet Yui.
And according to Orochimaru, not giving dinner is just a light punishment, but even such light punishment led Haku to master quite a lot of Water Release Techniques in a short time and at such a young age. This shows that Haku's talent is really exceptional.
'If Haku could become so dangerous and strong with just wandering around as a mercenary under Zabuza's tutelage, then his future achievements will undoubtedly be highly exceptional under Orochimaru's teachings!"
