Uchiha Hideki, who was barely alive a few moments ago now exuded a chilling aura as the tomoe in his Sharingan kept spinning rapidly.

Yama was observing Hideki's state with his Tenseigan and noticed that the Four-Symbols Seal could hardly restrain the incredibly strong chakra fluctuations which suddenly exploded like a volcanic eruption, the tomoe seems to be only a step away from merging into a different pattern. ​​

The Four-Symbols seal seems to be losing its effectiveness as many distortions started to appear in the sealing symbols that were eroded for some reason.

"What…?" – Yama was surprised by this.

He didn't expect that the Four-Symbols Seal would start to erode, seeing this change he was reminded of how the Four-Symbols Seal applied by Yondaime-sama was eroded by the rush of Ryuumyaku Chakra when Kuroto extracted the Ryuumyaku chakra for the artificial tailed beast project.

But there was still a difference in the two cases, the seal applied to Hideki was also being rearranged at the same time as it was being corroded, he seems to have never heard of such a thing happening.

At this time, he noticed that the Chakra fluctuations in Hideki were getting more violent and uncontrollable,, he took a step back to distance himself and observed all the changes with a look of expectation on his face.

He didn't even need the Tenseigan to notice that Hideki's visual prowess was continuously rising.

But suddenly something unexpected happened, the chakra fluctuations suddenly stopped and immediately white foam mixed with red traces came out of Hideki's mouth, and his body started twitching and spasming rapidly as if he was under a panic attack.

"Shit…!" – muttered Yama, and immediately stepped to give Hideki a high dose of tranquilizer along with a dose of Diazepam. The medicine instantly helped in subsiding the twitching and put him in a deep sleep.

Looking at Hideki's collapsed state. Yama sighed in disappointment.

Powerful emotional stimulation can indeed bring out the true potential hidden within the blood of Uchiha, but not everyone has the necessary willpower and mental fortitude to endure such emotional breakdowns.

Not everyone can endure to such an extent and past a certain level of emotional torture is the point of mental breakdown.

Uchiha Hideki was unable to activate the Mangekyou Sharingan even after witnessing the death of his brother and entered a panic attack implying that this level of emotional torture was past his mental breakdown point, as such his aptitude may not be enough to awaken the Mangekyou Sharingan.

Shaking his head helplessly, Yama walked out of this cell while and ordered the wooden puppet, "Clean up this mess and prepare for the next test in the adjacent prison cell."

The 'Uchiha Ryota' that was crucified on the metal cross and killed before Uchiha Hideki was just a low-quality clone he cultivated using Uchiha Ryota's DNA.

If not for Hideki's poor condition, broken spirit, and the restraint of the Four-Symbols Seal, Hideki would have undoubtedly figured out that it wasn't his brother Ryota.

This is because the clone does not have Ryota's Chakra trace, nor does it has the Sharingan.

Dojutsu requires mental power to activate the eyes, so even if Kuroto could perfectly clone Uchiha Ryota's body, the clone would not be able to use Sharingan.

This is the weakness of the current Cloning technology.

Coming to his study room, Kuroto took off his Yama mask and recorded all the details of the test conducted on Uchiha Hideki, as well as the result.

Being done with this, he glanced at the 'Uchiha Hideki' clone which was crucified.

The two clones he cultivated using Uchiha Hideki and Uchiha Ryota DNA were actually cultivated using a high amount of nutrient solution without even minding the cost, but strangely enough, a problem occurred and the two clones he obtained were of very low quality, they can even be considered as defective by Kuroto's standards.

Kuroto understands that Uchiha Ryota is more cunning than his brother, therefore, he decided to test this method firstly on Uchiha Hideki.

The test went quite smoothly and effectively if not for the last failure because of Uchiha Hideki's mental breakdown that resulted in overall failure.

Now Kuroto has to pin his hopes on Uchiha Ryota and considering that Uchiha Ryota's mental fortitude is much higher than his elder brother's, so the possibility of success is also higher.

After Putting on the Yama mask, he arrived in front of 'Uchiha Hideki' Clone and used a Kunai to carve out various wounds and cuts, which would let Ryota see just how much torture Uchiha Hideki has borne since he was kidnapped.

It only took him about half an hour to do this.

Although all these wounds appeared to be freshly inflicted, it isn't anything strange. This is because of the presence of Iryo Ninjutsu, it is common to heal the wounds and injuries of the prisoners to carry out repeated torture.

But even after he was done with all this, He still felt that something was amiss about Uchiha Hideki's clone, but he can't seem to figure it out. Uchiha Ryota is too cunning, therefore, Kuroto can't help but be too cautious about this.

For this reason, he didn't rush it and carefully thought and tried to figure out what made him feel as such.

Suddenly his gaze landed upon the clone's closed eyes and he finally realized what was amiss.

Kuroto immediately said to the wooden puppet, "Gouge out his eyes too!"

The wooden puppet followed his command and dug out the clone's eyes.

Now all that was left in the eye sockets were a pair of bloody eye sockets, which increased the visual impact and the convincing power of this clone.

Ryota, maybe cunning, is still an Uchiha after all, it is in the nature of an Uchiha to be affected by their emotions, seeing that his brother's Sharingan has been dug out, he would obviously go out of his mind as such his judgment power will also drop.

After nodding to himself that everything was in order, Kuroto muttered, "Let's see if this results in a success or another failure!"

With that, he walked out of his study and proceeded to the prison cell Uchiha Ryota is kept in…
