After memorizing the whole scroll, he burned it into ashes, then closed his eyes started practicing the sealing art.
The first step is to control the chakra meticulously, which is very easy for him, then connect the chakra, which overflows through all chakra nodes, and compress it in the mind for later usage.
As for how to store, this is the second part: create a seal space in the mind; it is like those seals and formations.
After creating a separate space in his mind, which was also easy for Aoi because of his enhanced soul and talent in space.
Also, as Uchiha, he has a Yin chakra and a Yang chakra. While Aoi started storing the chakra, instantly he felt his Yin chakra in his body reducing at alarming rate. After a while, he sensed that his Yin chakra balanced the Yang chakra.
"It almost reduced one-third of my chakra, was practicing this art so resource intensive." Aoi's brow furrowed, feeling it's a loss-making business, then he felt something, looking at his cell and yang, which had been slowed before, become a little active and increasing alongside his yin chakra balacingly.
Aoi raised his head glanced at the mirror, looking at the smooth forehead. 'It seems it will take a while for the mark to become visible; it took Sakura three years to condense it after storing chakra; in my case, it will take a few days if I squish my cells regularly.' Aoi nodded thoughtfully.
Then he devoured the charkra from his cells. The next moment, a warm current spread through his whole body. Aoi opened his eyes, feeling his cells were replenishing at an alarming rate. 'Finally, the yang chakra is showing its properties; it was truly suppressed before by my Yin chakra.'
Aoi then waited for cells to recover; in just three hours, they recovered. Looking at the deep night, he squished them again.
Instantly, he felt exhaustion from the body, but still, he hasn't reached the limit like before.
Aoi was truly surprised. 'As expected of the Yang attribute, also known as the ultimate in vitality,'
This time, it took his cells a little more time—about four hours—because of exhaustion. Instantly, he squished these cells again and squeezed every ounce of chakra out.
His vision turned dark, and he finally fell to death after a while.
Resurrection!!!
He opened his eyes, looking at the sun rising up in the sky.
Growl!!!
His stomach is gurgling like an angry lion.
He stood up and appeared outside, visited the famous ramen shop, and ate a few bowls amidst the happy expression of the owner.
Then he turned around and left, walking toward the hospital. After bringing some fruit for Sasuke, looking at him, not talking to him, and turning his head away, Aoi didn't care; he was just here to complete formality. Who will babysit a child like Sasuke?
He left the hospital and halted near the Hyuga house, looking at the guard's white eyes. 'I also have the dormant genes of Byakugan from Kaguya; probably I should try awakening all those dormant genes in my gene chain and awaken every bit of talent in this dimension, because it is an opportunity for me; these talents are going to be original talent beside my Infinity talent. I found out they are awakened by my original soul, not linked with my Infinity talent; this dimension is really a little different from other dimensions,' Aoi thought, then walked forward toward his own house.
"Are you from the Uchiha clan?" Instantly, a voice sounded behind him.
He halted and turned around, looking at the white eyes of a middle-aged man. 'Hyuga patriarch, Hiashi Hyuga, what does he want from me? Wait, he sensed my chakra and also my Mangekyo color; although I conceal them, Byakugan can easily see through them.'
"I am indeed from Uchiha." Aoi replied calmly, then asked curiously, "Do you need anything?"
Hiashi was surprised to see Aoi's calm expression. 'It's interesting; this kid still thinks he is anonymous, so calm.'
"Uchiha boy, it seems your survival of that massacre wasn't a coincidence." Hiashi spoke calmly, looking at him.
Aoi glanced at him, then nodded calmly. "Well, you are right; I used the ability; I awakened and saved my life." He replied calmly, then asked, "Do you want to ask anything else?"
"Ha ha ha, little kid, you really are different. I thought you would panic at least, but it seems I was wrong. The Uchiha clan really is a cradle of genius; don't worry, I won't report you." Hiashi laughed loudly, then waved his hand and walked away.
Aoi glanced at his back speechlessly, then shook his head and said, "I was so calm because you are going to forget everything."
Hiashi halted, his face changing. The next moment, everything turned into an illusion.
Recall!!! 4 minutes
Standing outside the hospital gate, Aoi glanced around, then walked on another path and returned to his house.
"Well, it's time to start the blood limit combination and explore more three-line and four-line blood limits." Inside his lawn, he started combining the chakra natures again; he already has seven attributes now.
…
Time Passed,
Five years later,
"Well, it seems the show is going to start finally." Aoi muttered thoughtfully, turning his head in the direction of the village. While sitting on the cliff edge beside the Hokage faces,
He is now a twelve-year-old boy with an extremely handsome appearance, spiky hair style emo bangs on both sides, and a hair covering his forehead in the middle all the way to the nose, revealing both eyes aside. Some hair threads hang on both eyes, which makes his appearance more lethal for those females. His slim yet perfectly proportioned body, whether it's height or appearance, is flawless.
His hair style and appearance almost match Noctis in FF.
A calm wind blew off his cheek. Aoi raised his head, the hair bangs scattered around to the sides, with the wind revealing his closed eyelids.
"The warm wind has a little cold sensation; it seems it's going to be rain," Aoi muttered thoughtfully.
