It was already evening when Kirito left Kawaki's house, and he was now full of energy from gorging on a medicinal meal that effectively restored chakra and got rid of fatigue.
"Yo, Kirito, you've been studying sealing jutsu with Mito-sama for so long today, have you eaten yet? Do you want to come to my house to eat, there's enough rice to go around."
"Kirito, today's spirit is good, usually you look sick, you should pay attention to your rest."
"Little Kirito, that dumb kid in my house's learning rely on you, don't care about my feelings, punish when you need to, scold when you need to, as long as his grades improve, I'll ask you to teach him a very powerful ninjutsu ..."
...
As Kirito walked through the clan territory of the Senju, many of the Senju clan greeted him in a friendly manner with genuine smiles on their faces.
Children are very perceptive to the malice and kindness of others, especially orphans.
Kirito loved the Senju because the people here were all very simple-minded and friendly, and they all cared for him in their own way after realizing that he was Mito's disciple as well as an orphan, keeping his heart warm and fuzzy.
Unlike the cold and dark chakra of the Uchiha's people, he could clearly feel that the chakra of the people living here were all very sunny and warm, giving people a very reassuring feeling.
"What a bunch of good people, it's too bad that they're dying out in this village like this."
Kirito thought so.
He wondered why the Senju Clan had disappeared from Konoha in the later years. In the later anime, only Tsunade was still active in the shinobi world.
He used to be tending towards the idea that the Senju clan had responded to the call of the second hokage by voluntarily giving up their family name and changing their surname to integrate into the Konoha.
But after coming into personal contact with the Senju clan, he realized that things were not that simple.
The demise of the Senju clan was mainly due to the war.
The first and second hokages were undoubtedly the honor of the Senju clan, and this honor was the pride of the Senju clan, something they would fight to the death to protect.
However, after the death of the two hokages, this honor became a heavy burden for the Senju clan.
Countless people of the Senju clan wanted to restore and protect this honor.
Just like Kawaki, countless children of the Senju clan grew up under the honor of these two great men, following the dream of hokage since they were young.
To this end, they threw their heads and blood to carry out the Will of Fire that protects the village.
In both of the Shinobi World Wars, Senju was the main force in the Konoha ninja clan, always at the forefront.
And the hostile shinobi were afraid of the Senju clan to produce another Senju Hashirama and Senju Tobirama, so they would choose to prioritize the killing of the Senju clan in the war.
All these reasons eventually led to a large number of young and strong people of the Senju clan dying in the war.
Nowadays, in addition to Mito and Tsunade, there are no longer a lot of battlefield strength, only a group of old and weak women and children left.
Following the original plot, after Mito's death, Kawaki's untimely death, Tsunade's heart-breaking departure from the village and her self-loathing, the Senju completely fell, and eventually had to give up their surnames and voluntarily integrated into Konoha, and only then were they freed from this heavy honor.
How can we stop the demise of the Senju clan?
This question, Kirito's heart has long had the answer, but before that, he first need to master enough strong power to be able to do.
Half an hour later, he returned to the orphanage.
The face of the orphanage has also changed a lot, everyone is trying to pursue a better life, so with enough financial resources, the orphanage built new houses, and added many toys in the courtyard, such as slides, swing, bars, and other toys for children to play with.
Kirito himself got a house of his own.
Upon his return, he first greeted Yakushi Nono and the others before heading back to his own house before arriving at the entrance to the basement.
Since his basement held many important as well as dangerous things, he had set up a sealing jutsu at the entrance to conceal his entrance in order to prevent enemies and playful children from entering by mistake.
This was the result of the sealing jutsu he had learned from Mito during this time.
However, the level of the sealing jutsu he currently set at the entrance was still low enough that someone with a slight mastery of sealing jutsu could unlock it, but it was sufficient for preventing children from the orphanage from mistakenly entering.
" Release."
Kirito made a quick seal with both hands, then pressed on the floor.
In the next moment, a large amount of sealing jutsu formed from chakra sprouted from the otherwise empty floor, and the floor began to slowly move away, revealing a staircase leading underground.
As Kirito walked down, the sensor lights arranged at the top of the basement lit up.
There were roughly three types of things placed in the basement, one being books, one being scrolls, and the last being glassware.
The books in the basement were all purchased by Kirito at the bookstore, and the categories were mainly medicine, electricity, and biology.
The science and technology of the Shinobi world was actually quite advanced, with electricity and biology developing quite well, Kirito spent a little more money to easily purchase many related books, thanks to these books, he now had a good understanding of medicine, electricity and biology.
The scrolls were Kirito's collection of ninjutsu, most of which were sealing jutsu, followed by lightning jutsu and Yin jutsu.
The main sources of these jutsu were Mito and Chizuru, all three had jutsu libraries in their homes. The sealing jutsu were organized by Kirito who learned them from Mito, while the lightning ninjutsu and Yin ninjutsu were obtained by Kirito through Chizuru's contact for payment for sparring.
There aren't many Lightning Ninjutsu and Yin Ninjutsu, both have only one at the moment, which are Lightning Release - Lightning Balls and Yin Release - Mind Reading, respectively.
Kirito hadn't yet cultivated his lightning and yin attribute chakra, so he was only able to stare blankly to these two jutsu for now.
As for the glass containers, there were a large number of them, one large and one small, containing many creatures, bugs, plants, various organs and so on, which the most numerous was some red hair, all of the things soaked inside some green solution.
"Worthy of the bloodline of the Uzumaki clan, even if it's just hair that falls out as long as it's supplemented with nutrients it can be revitalized and form flesh and blood tissues."
Kirito came to one of the largest glass vessels in the basement and looked at a piece of flesh tissue inside that resembled a heart that was generally not in motion and smiled, a hint of fervor flashing in his eyes.
The piece of fleshy tissue in the glass vessel in front of him had started out as nothing more than a piece of Uzumaki Mito's hair that he had secretly collected, and after nearly a month of cultivation, it had taken on a whole different appearance.
He could feel that the fleshy tissue was not only filled with exuberant vitality, but also gave birth to chakra.
Chakra was the source of energy for all jutsu, only by grasping immense chakra could one become a powerful ninja, or so Kirito thought.
Therefore, he greatly envied people like Mito and Kawaki, who were born with immense chakra, and aspired to possess this power.
However, he wasn't a member of the Uzumaki clan and couldn't obtain the key to this power.
Thus, he planned to learn from Obito and integrate the bloodline of the Uzumaki clan into his body through biotechnology.
Now, the Bloodline Fusion 1.0 experiment was about to begin.
"Let's see if you can survive after mixing in my blood."
Kirito thought with anticipation before dropping his own blood into the middle of the glass vessel.
