Hakushi saw Doctor Kataki agree, then turned and left.

Ka.
With a soft sound, the white wall suddenly became transparent.
Normally, this wall is actually transparent, and after activating the mechanism, patterns appear on the wood and begin to circulate on the transparent wall.
That's the glow of chakra.
Even if outsiders infiltrate here, they cannot feel the hidden entrance.
Asuka curiously examined all this.
This is the most important comprehensive research base underground in the First Military Region of the Land of Demons.
The place he has entered now is the personal space territory of the staff.
Like opening a revolving door, Asuka pushed open the transparent door flashing with chakra patterns and entered the room.
Upon entering the room, he saw a middle-aged man wearing a monocle sitting in front of a computer, typing on the keyboard, with the light from the screen reflecting off his monocle, working seriously.
The screen displays a design drawing of some kind of super-large tool, which is extremely precious research material.
"Is it young master Asuka? Please have a seat."
Dr. Kataki did not expect Hakushi to send Asuka over so quickly, but he didn't mind at all and just treated Asuka with a normal attitude.
"Hello, Doctor Kataki."
Asuka politely bowed, then sat in a chair not far from Dr. Kataki, his expression a bit reserved.
"No need to be so formal. I've generally heard about your situation from Lord Hakushi. Following to learn from me is no problem. However, our work can be very tiring, and it may be accompanied by the annoyance of failure... Hmm, it's a bit untimely to talk about this now. Here, this book can be taken back for reading, young master Asuka. After one month, I will conduct a test on young master Asuka. After the test, we can continue to delve deeper."
Doctor Kataki stood up from the chair, picked up a heavy book beside the computer, and placed it in front of Asuka.
Asuka took it and found it extremely heavy, yet it didn't feel burdensome to him.
"I understand, Doctor Kataki."
Asuka knew this was a test from Doctor Kataki for him, and he treasured the opportunity his father Hakushi had fought for, intending to make the best of it.
"Okay, that's settled. I still have some matters to attend to here. Young master Asuka can freely tour here. If there are parts you don't understand, you can come find me during any week's break to ask me, I'll be available then."
Asuka has not completely abandoned the identity of a ninja. Often times, he still needs to attend Ninja School to learn ninja skills.
Weekends are dual holidays, Saturday and Sunday.
At that time, it's just his weekends, so there's ample time to answer Asuka's questions.
As for talent, it needs some time for observation, not too hasty conclusions.
Interest is just a foothold, but whether it can pry open the door of scientific truth requires talent in this area, and diligent accumulation.
Having said that, Doctor Kataki picked up a stack of printed drawings, hurriedly left the room, leaving Asuka alone to tour his office.

"Fire Style: Great Fireball Technique!"
In the enclosed training ground, Ruri performed sealing and quickly spat out a huge fireball from her mouth, fiercely flying toward the distant stake.
But that was not the end, Ruri's Sharingan suddenly began to change, starting from the basic tomoe form, extending into the Mangekyo Sharingan.
The Mangekyo Sharingan in her left eye released a powerful donjutsu, acting on the fireball that was being shot out.
In an instant, the projectile fireball immediately expanded and grew larger, burning the space with a terrifying presence, rapidly heating the surrounding air.
Afterward, Ruri's silhouette vanished from the spot, a fierce and fiery lightning twirled in the place, while she appeared before the large-sized fireball about to hit the stake.
Without any hesitation, she grasped a dark red sword blade condensed by chakra in her palm.
That was the sword that only appears in the Susanoo state.
A manifestation by chakra.
This sword is very difficult to cut through the Great Fireball Jutsu amplified by donjutsu.
However, the left eye continued to release donjutsu, concentrating on the sword blade in hand.
The dark red sword blade surface immediately adhered a layer of azure light, striking down without mercy towards the giant fireball.
The slash trajectory of the blade left behind the frictional traces of lightning on the atmosphere, sounding with chirps.
The giant fireball was cut through extremely flat from the middle, brushing past Ruri's sides, only stirring her clothes and hair, with Ruri standing there unscathed.
Ruri looked at the dark red sword blade in her hand, with its azure light not yet dissipated.
The slash trajectory of the sword cutting through the fireball left behind the straight traces of lightning eroding the atmosphere, seemingly cutting through space, enduring and persisting.
Just looking from a distance, one's eyes would feel pricked by the sharp blade, forcing one to close eyes.
Its sharpness made space in front of the sword have no resistance.
Facing the reinforced Great Fireball Technique, it could also effortlessly slice open with one blade.
And this was merely the scaled-down sword of Susanoo, if manifesting in its full glorious form, then the boost of donjutsu on the sword blade would be even more pronounced.
Ruri was highly satisfied with her current state.
The enhancement from the Eight Thunder Gods Donjutsu was also beyond imagination.
