After making up his mind, Kuroto did not waste any time and started to act without any delay.
With the intention of carrying out a Blood Transfusion, Kuroto carried out all the necessary preparations for the Blood Exchange Operation and soon started the operation.
Blood Exchange Operation/Transfusion is obviously much simpler and easier compared to the cell or organ transplantation operation.
The real problem that Kuroto faced when carrying out the Blood Transfusion for the Fujin Clone was not any so-called technical difficulty or the lack of knowledge, rather, it was the lack of suitable vessels capable of holding Fujin Cloneās blood and the corresponding storage container that wouldnāt just disintegrate upon coming in contact with the decaying āAll-Killing Ash Bonesā particles.
It is no secret to Kuroto that the concentration of āAll-Killing Ash Bonesā particles has reached unusually high levels in the Fujin Cloneās Blood.
Before carrying out the operation, Kuroto even went as far as to conduct a few small tests and found that all the Blood Transfusion Tubes/Catheters, as well as most of the containers present in his laboratory, cannot be used to store the Fujin Cloneās Blood as they simply canāt withstand the disintegration upon coming in contact with the blood containing āAll-Killing Ash Bonesā particles.
Basically, within 15 minutes of coming in contact with the āAll-Killing Ash Bonesā particles contaminated blood; the vessels and container will start to show clear signs of decay and turn into pure ash within the next 5 minutesā¦
If the container is made up of āmetalā, it will quickly rust and oxidize, and if it is made up of āglassā, the structure of the glass will collapse as it starts to heat up and melt.
Because of facing this unreasonable problem, it took him a lot of time and effort before Kuroto managed to find a suitable material that could barely hold Fujin Cloneās contaminated blood.
The material he found is the bark of a tree that secretes a special type of āGlueā on its surface. The only reason such a thing appeared in his laboratory is that Kuroto was testing out various colloidal materials that would be suitable in replacing the āGlueā used by Hiroku at the time of making the Chimera Buds.
The results of those tests were obviously disappointing, so at that time Kuroto had just discarded this Tree bark and didnāt care too much about itā¦ but now that very same tree bark is proving to be quite useful.
Kuroto never expected that this Tree Bark which secretes a special type of āGlueā would actually be capable of withstanding the disintegration upon coming in contact with Fujin Cloneās contaminated blood, but now that he has finally found something he can use to store the blood, so the Blood Transfusion Operation can finally begin.
So it began, and lasted a few hoursā¦ After a few hours, the blood transfusion operation was finally completed.
The Transfusion Operation went smoothly without any major accidents in the middle, and as the blood in the body of the Wind Clone B was quickly transfused into the body of the Fujin Clone, all the vital signs of the Wind Clone B also gradually disappeared.
With the āAll-Killing Ash Bonesā particlesā contaminated blood now exchanged with the clean blood; the disintegration of the Fujin Clone also slowed down.
The next thing Kuroto did was to properly and securely store the contaminated blood for later research, then dispose of the Wind Clone B as it had already lost all vital signs and would be of no use now.
With all those pesky tasks completed, Kuroto again came towards the bench on which the Fujin Clone was lying and observed it very carefully.
After a while, he frowned, then loosened his eyebrowsā¦ In order to better understand the status of the Fujin Clone; he directly used the Tenseigan Soul Descend and transferred his soul from the main body to the Fujin Clone body.
āCoughā¦ā After coughing for a while to get rid of the blood clots jamming the trachea, Kuroto climbed off the operation table; staggered a few steps then heavily collapsed on the ground, which wasnāt anything strangeā¦
Although the disintegration of the Fujin Clone body has stopped because of the Blood Transfusion, the original damage, and injuries of the body, as well as the other major organs, have not been treated, so obviously; the body functions are not back to normal.
In the fight against Hiruko, Tendo, and āMadaraā, several of his organs, many major vessels, bones, and even muscle fibres throughout the body had been injured or damaged severely. And considering these damages, itās nothing strange that the body has lost all mobilityā¦
āNow that I see the condition of this Clone body, it appears that I went a bit too far in using the Fujin Cloneā¦ā Kuroto sighed while resisting the sharp pain he was feeling all over his body.
But Kuroto didnāt regret it, because if he didnāt do what he did by going a bit too far in using the Fujin Clone during his fights with Satori, Hiruko, Tendo, and āMadaraā, then the consequences that the village would have suffered might not have been just about a few thousand deathsā¦
At the price of a few serious injuries of this Clone body if Konoha can continue to exist, and many of his friends and families can continue to live, then this is not too big of a price to pay.
""
Whatās more, those battles have also been proven to be beneficial to Kuroto from an overall perspective, as his mastery over all the powers and Kekkei Genkai of the Fujin Clone has also improved to varying degrees.
And please donāt underestimate all these improvements in fighting skills, Kurotoās ability to fully bring out his fighting power is inseparable from his major improvements brought by frequent participation in high-intensity life-and-death battles.
One of the reasons why Nagato retreated to a crippled state this time was also because he seriously lacks the experience of fighting against people of the same level as him.
Because Nagato hasnāt really fought that many life-and-death battles against someone of similar strength as him, therefore, when faced with the moment of real crisis, his response wasnāt up to the standard, he did not use the best tactics that he could have and as a result, caused many mistakes and misjudgments in the battle.
One of those extremely serious misjudgments was his inability to see through Kurotoās faƧade, as Kuroto managed to fool him without much difficulty just using his own experienceā¦
Therefore, even these itsy-bitsy improvements are very important as they can bring about major differences over the course of several years.
Anyway, after putting away this thought, Kuroto sat on the ground in a cross-legged position; and instructed the Kazekage puppet to bring over Karin.
Kuroto is not that proficient in Iryo-Ninjutsu, so although, he has temporarily solved the major problem of the Fujin Clone by performing a blood Transfusion, he has no immediate method of treating the injuries that the Clone Body is suffering from.
Fortunately, enough, Karin is also present at Ancor Vantian. With her around, just a single bite can provide the necessary healing chakra and heal almost all the major injuries
Although Kuroto doesnāt really want to use her in such a manner, he doesnāt have any other option at this point because Karin hasnāt learned Iryo Ninjutsu eitherā¦
Thinking so, Kuroto sighed, āIāll have to find a way to teach her Iryo Ninjutsu tooā¦ā
While Kuroto was busy in his thoughts, under the guidance of the Sandaime Kazekage Puppet, Karin came to the laboratory with a look of curiosity. For her, this is the forbidden Zone, and this is the first time she has foot anywhere near Kurotoās laboratory, so when she looked around, she felt that everything was full of novelty.
Seeing Karinās arrival, Kuroto who was currently controlling the Fujin Clone beckoned her towards him.
Karin nodded and walked up to him, and called out, āFujin-sama!ā
Having been living in Ancor Vantian for quite a while, Karin and Gaara have seen and met Suijin, Tsukihi, as well as Fujin. Of course, they are not aware of the fact that all of them are just Kuroto controlling different clone bodies; what they think is that Suijin, Tsukihi, and Fujin are all Kurotoās subordinates just like the Kazekage puppetā¦
And seeing Fujinās state, Karin was a little worriedā¦
With Karin standing next to him, Kuroto said lightly, āAs you can see, I have suffered several serious injuries and need your helpā¦ will you help me?ā
There was no need to ask, as even before Kuroto had asked, Karin had already rolled the sleeve of her Kimono and proactively stretched out her armā¦
Although she didnāt seem to hesitate and actively stretched out her arm without even Kuroto asking, he could still see that her arm was shaking in nervousness and her face had a slightly timid expression, and thought, āIt seems that she remembered the painful memories of her motherās experience in Kusagakure.ā
Shaking his head slightly, Kuroto didnāt say much and took a gentle bite at her armā¦
As soon as he bit on Karinās arm, a gentle Yang Chakra entered his mouth and soon passed through his entire body giving a warm feeling.
The feeling was like soaking in a hot spring, the whole body felt warm, and the unbearable pain in his body instantly started to dissipate as all the injuries started to heal rapidlyā¦
At the same time, Kuroto, with his Byakugan could clearly see that Karinās body was also becoming thinner.
Upon realizing this, he did not burden her too much and immediately stopped after the major injuries were healed. After all, Karin is still too young, and excess overdraft of her Chakra will seriously affect her health and deteriorate her foundation.
Stopping halfway, Kuroto breathed a sigh of relief and said while gently patting the girlās head, āThanksā¦ with this, I am healedā¦ā
At the same time, Kuroto canāt help but feel enviable towards the Uzumaki physique. Although Karin at this point in time is just an ignorant young girl who is not even 10 years old, when it comes to her passive ability as a medical-nin, she is by no means inferior to Tsunade-hime, the number one Iryo-nin in this Shinobi World.
While Kuroto was feeling enviable, Karin obviously noticed that not all of his injuries are healed, so, she still didnāt roll back the sleeve of her Kimono and said, āIā¦ I can still hold onā¦ā
Kuroto shook his head, āDonāt worry about itā¦ the major injuries are already healed, rest will heal automaticallyā¦ So, I am fine now, and you can go back and restā¦ā
āOkayā¦ā Karin nodded slightly, then under the guidance of the Sandaime Kazekage puppet, she left the Forbidden Zone.
With Karin and the Kazekage Puppet gone, Kuroto observed the state of his Clone body using his Byakugan, then carried out a basic assessment of the physical body.
And based on the result of the assessment, he concluded that as long as he doesnāt use Chakra and more specifically, doesnāt use Shikotsumyaku, then the Transfused Blood can continue to maintain all the activities of the clone body for the next three to four months before becoming contaminated with the āAll-Killing Ash Bonesā particles.
āIt seems that I will have to create a few more Wind Clones in the future to serve as backup blood tanks for the Fujin Cloneā¦.ā
