It is impossible to restrain a Jonin one such as Uchiha Hideki by simply relying on drugs.

What's more, Uchiha Hideki's drug resistance seems to be a bit higher than normal, therefore simple paralysis and sleeping agents aren't enough to ensure that he wouldn't run away. ​​

And Four-Symbols Seal is not only one of the best Fuinjutsu to seal the Chakra of a Shinobi but also the technique Hyuga Kuroto is best at.

With the Four-Symbols Seal applied, whatever Chakra Uchiha Hideki's will be able to refine will constantly be drained therefore sealing his Chakra, such that the drugs he is injected with will become more effective, cutting all the possibility of his escape.

After confirming that the mechanism of the Fuinjutsu was working exactly as he intended, Yama again started printed the hand seals.

By now, Uchiha Hideki could hardly maintain his Sharingan because of the Chakra drain and was more frightened, "Just what are you doing all this for!?"

Yama did not answer, and after completing the hand seals ha again reached out and pressed his hand on Uchiha Hideki's chest, "Fuinjutsu: Contract Seal: Seal!"

Followed by his words, the sealing symbols spread on Uchiha Hideki's chest and instantly severed his contract with the summoning world.

In the shinobi world, there are all sorts of strange summons.

In addition to the most common type of animal summons used by shinobi for summoning beasts, there are also Communication Summoning, Weapons Summoning, and Reverse Summoning that can be used by summoning beasts on their contract partners, as well as summoning used by a ninja on another ninja.

And if Uchiha Hideki's summon beast has the ability to perform the reverse summoning, then it is possible that he will be able to use Reverse Summoning to easily rescue Uchiha Hideki from here.

Therefore, Yama used the Contract Seal to cut away his connection with the Summoning World.

Although the Summon Beasts capable of performing Reverse Summon are rare, and Yama does not believe that Uchiha Hideki's summon partner would be capable of such a feat, but he decided to use Contract Seal to eliminate the slightest of the possibility of his escape from here.

Feeling that his connection with the summoning world was cut off, Hideki was more horrified and spoke with a horrifying expression, "You… you even know the Contract Seal?"

Both Four-Symbols Seal and Contract Seal are Uzumaki Fuinjutsu and with the destruction of the Uzumaki Clan very few individuals can use these techniques.

Therefore, these techniques are mostly exclusive to the shinobi of Konohagakure.

Yama who has completed the seal and verified its effectiveness spoke indifferently, "What's so strange about this?"

Uchiha Hideki stared at Yama and asked, "You are from Konoha, aren't you?"

No doubt Uchiha Hideki suspected this possibility.

Yama was surprised as he felt the violent fluctuations in Uchiha Hideki's emotions; understanding what was happening, he had a Cheshire grin under the mask and spoke, "Oh you noticed it so soon? As expected of an elite Jonin of the oh-so-great Uchiha Clan!"

Seeing that Yama did not deny, Uchiha Hideki was suddenly furious, "Who asked you to do this? Was it Sandaime? Or Danzo?"

At this time, Yama could see the violent fluctuations in Uchiha Hideki's chakra affected by his erratic emotions, suddenly he tried breaking free and it seemed even the Four-Symbols Seal wouldn't be able to completely suppress the flaring chakra in his body.

Yama observed Hideki's restlessness, and thought, 'Hmm, maybe I can use this method to continue irritating him!'

With that decided, he spoke with a chuckle, "Who asked me to do it? Is it really that important, after all, you are going to die anyway?"

However, Uchiha Hideki seemed to care about this and spoke while gritting his teeth, "It's that bastard Danzo, isn't it? He has long held ill-intentions towards the Uchiha Clan!"

Yama didn't speak anything, neither agreed nor denied.

Seeing Yama silent, Hideki frowned and asked with uncertainty, "Was I wrong…? Then is it… is it Sandaime?"

Since Yama had already found a topic to anger Uchiha Hideki so he deliberately didn't answer Hideki's question and incited him, "Don't worry about that, look around you, what do you see… this place is very big and many people can be kept here, many-many people, you understand what that means, don't you? You won't be alone for very long… this place will be filled with the Uchiha!"

"YOU-DESPICABLE-PSYCHOPATHIC-BASTARD! Conspiracy, all this is a conspiracy against the Uchiha clan! That hypocritical geezer Sarutobi really wants to eliminate all the Uchiha… I can't stay here any longer, I have to warn the Patriarch!"

Yama tried changing the subject making Hideki convinced that all this was done under Sandaime's instructions, so he was angrier, up until now; there are still many Uchiha shinobi who believes that Sandaime wouldn't hurt the Uchiha Clan but Hideki was now convinced that hypocrite Sarutobi Hiruzen also bears ill intentions towards the Uchiha clan!

As such he was madly trying to break free of the restraint, therefore, the prison room was filled with angry curses and the sound of chains clanging.

Yama didn't stop Uchiha Hideki but observed the Chakra fluctuations in his body with his Tenseigan.

Undoubtedly, Uchiha Hideki managed to extract some chakra while in rage, even under the suppression of the Four-Symbols Seal.

'Not enough… it's still not enough for him to awaken those cursed eyes!' – thinking so, Yama pondered a moment and asked tentatively, "By the way, I remember you have a younger brother, don't you? What was his name again? Haruto? No! Ryo? Not this either! Yup, Ryota! His name is Uchiha Ryota, right?"

As soon as Yama finished his words, Hideki looked at him with a murderous look as if he would chew Yama alive, "Don't you dare touch him!"

Yama obviously didn't care about Hideki's warning and muttered, "If I use the elder brother as a bait, it should be easy to fool him, umu… yeah let's do this, next target Uchiha Ryota!"

Hearing that the masked freak wanted to use him as the bait to lead his own brother into a trap, Hideki's Sharingan activated under the intense rage he felt.

Yama observed with a surprise and thought, 'Hoh? He manage to activate the Sharingan even with the continuous Chakra Drain, that's quite impressive?'

However, as Yama expected, because of the continuous chakra drain, the Sharingan couldn't be kept activated for more than a few seconds and was soon deactivated.

Shaking his head in disappointment, Yama thought, 'It appears that simple anger is not enough for him to awaken the Mangekyou Sharingan, maybe I will have to change my approach!'

…

On the side of Konoha.

After gathering the ninjas, Uchiha Fugaku led the teams across the outer wall without any delay to chase after the ninjas of Amatsukami.

But after following the enemy's tracks for a while, he stopped.

Not only him but the entire team stopped and each of them had a frowned expression, looking around blankly.

It's because when they started following the tracks and got past the training field there were still obvious traces left but after traveling a few miles all the clues disappeared suddenly.

It was as if the enemy didn't move any further.

Everyone couldn't help but have the same thought, 'How come the traces all disappeared from here?'

Uchiha Ryota spoke with an anxious look, "It couldn't be that he flew away! If we search carefully, we will definitely find something!"

Fugaku's face sank when he heard Ryota's words, it's because he heard that Suijin of Amatsukami could strangely fly away using Ice Mirrors, so they can't deny the possibility that the enemy might have really flown away from here, otherwise, it is impossible to explain that all the clues suddenly disappeared!

After all, even with the Sharingan, they can't seem to find anything.

It must be known that with the Sharingan, the Uchiha Clan is second only to the Hyuga Clan in tracking and pursuing, and since they are unable to find anything even with the help of the Sharingan can only have one explanation, there is no clue here in the first place!
