Yama did not care about Uchiha Ryota's swearing.

At this time he was observing Uchiha Ryota's chakra fluctuations with the Tenseigan. ​​

Unlike Uhciha Hideki, Ryota does not seem to be able to resist the chakra draining effect of the Four-Symbols Seal.

So even under the effects of extreme anger that he felt right now, there were no signs of Chakra fluctuations nor was the Sharingan activated under the emotional stimulation.

After observing this for a while, Yama shook his head in disappointment.

Similar to Uchiha Hideki the emotional stimulus of 'Anger' is insufficient to awaken the Mangekyou Sharingan or even be able to break free of the restraint effects of the Four-Symbols Seal.

With that conclusion, the first stimulation test was over, and Yama again clapped his hands.

Clap… Clap…

With the sound of Clap echoing in the room, the screaming of Uchiha Hideki that could be heard subsided and faded away.

Ryota who was tied to a stone pillar similar to Uchiha Hideki couldn't help but ask, "What on earth do you want from us? If Sharingan was what you kidnapped us for then you already have it! Why torture nii-san!?"

Yama did not bother to answer Ryota's question just calmly and silently walked out of the cage ignoring Ryota.

…

Inside the Uchiha Hideki's prison cage.

Uchiha Hideki who was tied to a pillar was panting heavily and tried to catch his heavy breathing, his body was full of scars from cut wounds and piercing wounds, some even had blood seeping out of them.

There were many bruises that made the skin purple, a few burn marks that made the skin black and a few of his fingers were also broken or bent in unusual directions with nails missing in all of them or impaled with metal needles.

Overall, he was in a very severe state, clearly indicating the picture that he went through severe torture that is akin to experiencing hell and Kuroto can guarantee that even the Slug Sannin Tsunade would have too much trouble healing him.

In front of Uchiha Hideki stood an upright wooden puppet that was one of the many puppets seized during the third great shinobi war when Konoha was in a conflict against Sunagakure.

The puppet itself is not of any extraordinary value or functioning, it can not use any ninjutsu, the only function it is capable of is to shoot out the pre-stored shuriken and Senbon.

Since such a puppet does not have any research value, therefore, after being seized by the Konoha, all it was used for was to give experience to the shinobi on how to combat the Sunagakure puppet brigade.

And since Kuroto needed someone or something to keep watch of this Dungeon Prison in his absence so he used his Anbu identity to take this puppet from the warehouse.

After making it a self automata with the use of Tenseigan Chakra, just like he did with the Kazekage puppet, Kuroto also used the basics of what he learned about the Yin-Yang Release to give it some sort of sentience so that it can keep watch of this prison dungeon and the captive Uchiha that will be kept here.

Although its combat power is not much only reaching the level of a Chunin, it is still more than enough to perform many tasks, like execution, cleaning, pouring tea, helping in torture etcetera.

Walking inside this Hideki's cage, Kuroto who was still wearing the Yama disguise, waved his hand and ordered, "Alright, walk back."

Following the order, the puppet put away all the torture devices and stepped aside.

At this time, Uchiha Hideki glanced at Yama with a weary expression and asked, "I… I felt l-like… I heard Ryuto… p-please tell me… it w-was just my… my imagination!"

Yama shook his head indifferently and said, "No, it was not your imagination, he is in the prison cell right next to yours… and he would soon be going through exactly what you have been going for the past few days."

Hideki said with a pleading expression, "Please, whatever you want, I… I will do a-anything… I will g-give you every… everything… please… please j-just l-let him go!"

Yama thought, 'The emotional bond between these two brothers is really strong, with this confirmed I think I can proceed further.' – Not caring about Hideki's begging, Yama stated, "Unfortunately that wouldn't be happening."

Hideki was silent after hearing Yama's cold words.

He understood that at this point, that Yama would not let either of the brothers go.

Not to mention the two of them, Hideki has even started to fear that the entire Uchiha Clan would fall prey at his hands and be eventually destroyed.

And he can't help but sigh at this thought.

While Hideki was silent, Yama observed his condition with the Tenseigan, and after confirming that everything was in order he left the prison cell.

Coming to another room, Yama took out two notebooks with [Uchiha Hideki] and [Uchiha Ryota] written on the cover.

He thought a little bit and started writing in the notebook that contained the report about Uchiha Ryota.

[Similar to the case with Uchiha Hideki, the 'Anger Test' failed, solidifying the conjecture that anger is not the most suitable emotion to be used as a stimulus for the awakening of the Mangekyou Sharingan.

Additionally, Uchiha Ryota's visual prowess is better compared to Uchiha Hideki, so the probability of awakening Mangekyou Sharingan is higher.

Uchiha Ryota is also quite cunning and seems to have noticed that I was intentionally stimulating him, perhaps he has a degree of understanding on how to awaken Mangekyou Sharingan]

After writing up to here, Yama stopped.

In the past few days, Yama has figured out that he should not put too much hope in this plan of his and for that reason, his mentality is quite stable even after repeated failure.

Perhaps it is because there is no telling just what is the right amount of stimulation needed to awaken the Mangekyou Sharingan.

Therefore, he has also started to study different changes in the Sharingan under different types of emotional stimuli.

After closing the notebook, he did not stay much longer in the dungeon prison and returned to his post that was taken over by his Shadow Clone in his absence.

…

In the blink of an eye, a few more days passed.

The sudden disappearance of Uchiha Ryota was another slap in the faces of the Konoha management, and this time the entire village was stirred up.

All Konoha shinobi openly regarded the actions of Amatsukami as an open declaration of War.

For this reason, the amount of effort each shinobi was putting to raid and hunt down the black-market increased several folds, and strangely enough, many unrelated small organizations that were hiding became unlucky targets.

At the same time, a seemingly ridiculous rumor that seemed hard to deny because of the amount of weight it had and seemed justified under careful consideration started to flow out of the rumor mill, and the protagonist of this rumor was none other than Uchiha Shisui.

After hearing the rumors, Shisui was in a panic and quickly met up with Kuroto.

As soon as Kuroto appeared, Shisuihow had a crying expression exclaimed, "Kuroto-san, w-we are exposed, w-what do we do!!?"

These past few days, Kuroto has been busy either with the task that was assigned to Anbu Team-11 or with torturing out the Uchiha brothers therefore he did not pay enough attention to the sudden rumor, now listening to Shisui mention this, he was stunned and asked, "How do you know you are exposed?"

Shisui was a little anxious, "It has spread everywhere in the village and everyone knows that Uchiha Shisui is Homusubi of Amatsukami!"

When Kuroto heard Shisui's words, he felt that such a thing should not be possible and muttered in thought, "No, even if someone figured it out, spreading such a serious matter without any evidence is simply foolish!"

Shisui said, "But this news has already been spread in the village, what should I do now??"
