Improved Strength

However, beyond the bloodline enhancement brought by the Kotoamatsukami Mangekyo resonance, the potion also contained components that strengthened White Zetsu Cells, significantly increasing Uchiha Shūichi's Yang Chakra.

With Yin and Yang combined, Uchiha Shūichi's improvements in physique and Chakra were even greater than the enhancement brought by truly awakening the Mangekyo Sharingan and undergoing a bloodline ascension.

Most importantly, the potion had also eliminated the hidden drawback of the Kotoamatsukami Mangekyo. Although using Kotoamatsukami still required a period of cooldown, it would no longer cause his vision to deteriorate.

As such an absurdly powerful Dojutsu, Kotoamatsukami naturally had certain restrictions. It was not as though it could be used indefinitely as long as Dojutsu Power did not decline.

The more abundant one's Dojutsu Power and recovery ability, the more they could reduce Kotoamatsukami's consumption. For instance, if pure Hashirama Cells were used for recovery, Kotoamatsukami would only need two or three days.

If Uchiha Shūichi could also integrate Hashirama Cells into his bloodline, then now that he had truly fused with the Kotoamatsukami Mangekyo, the cooldown after a single use of Kotoamatsukami might drop to just one or two days.

In a sudden battle, Kotoamatsukami could probably only be used once. After all, no battle lasted twenty-four hours.

But if he used it to stir up trouble, even being able to use Kotoamatsukami only once every week or two was already more than enough.

Furthermore, the improvements brought by the Mangekyō Sharingan encompassed every aspect. Its boosts to genjutsu, perception, and dynamic vision far surpassed the Three Tomoe Sharingan.

Even without using any special Dojutsu, and even if he merely maintained the Three Tomoe state, the genjutsu cast through the Kotoamatsukami Mangekyo would still be unimaginably powerful. Even ordinary genjutsu could be enhanced to the level of A-rank genjutsu.

The Uchiha Clan's genjutsu in particular required neither hand seals nor preparation. It could be activated directly with nothing more than eye contact, making it vastly more powerful than the genjutsu of ordinary ninja.

My current strength is roughly equivalent to that of a Kage-level Ninja skilled in genjutsu, with Kotoamatsukami genjutsu as my trump card.

While Kotoamatsukami is off cooldown, almost no ninja at this stage can withstand my Kotoamatsukami genjutsu.

Perhaps only Nagato, who now possesses the Rinnegan, and special existences like Black Zetsu can resist my genjutsu.

But that depends on the information not leaking first. Once they know about Kotoamatsukami genjutsu, those top-tier ninja should be able to find ways to counter it, or at least guard against it.

Ninja intelligence was extremely important. In a battle between opponents of the same level, no matter how powerful a ninjutsu or secret technique was, once its details were exposed, a countermeasure could generally be found.

Even at the level of Uchiha Madara and Senju Hashirama, intelligence still remained immensely important.

Not to mention anything else—if Senju Hashirama had known of the existence of Izanagi during the Battle of the Valley of the End, Uchiha Madara's fake death would have become a real one.

Among Mangekyo Dojutsu, Kotoamatsukami stood in a class of its own. Its ten-year cooldown alone showed the gap between it and other Mangekyo Dojutsu.

But in the end, it was still within the scope of Mangekyo Dojutsu. It could not truly be without a solution.

Ordinary ninja could not resist Kotoamatsukami genjutsu even if they knew it existed, but battle-hardened Kage-level Ninja with varied methods could, given enough time, generally devise some means of prevention.

What a pity... If I could get both Kotoamatsukami Mangekyo, I could awaken Susanoo. That would be when I truly pull ahead of ordinary Kage-level Ninja.

Uchiha Shūichi sighed. Susanoo's greatest advantage was its unity of offense and defense, activating with a thought. Its strength far exceeded that of ordinary defensive ninjutsu.

A ninja's greatest weakness was their frail body. The vast majority of Kage-level Ninja could be killed by a single shuriken, while an Uchiha with Susanoo could make up for that weakness to the greatest extent possible.

What Uchiha Shūichi lacked now was precisely this kind of defensive ability. No matter how powerful Kotoamatsukami was, he himself could still be stabbed to death by a single kunai.

After leaving Orochimaru's Base and returning to Konoha through the Reverse Summoning Jutsu, Uchiha Shūichi took a deep breath of the night air, excitement appearing on his face.

In less than a month, he had gone from an Elite Jonin to a troublesome powerhouse even among Kage-level Ninja. Uchiha Shūichi felt that his plans were progressing even more smoothly than he had imagined.

I really have to thank Uchiha Shisui for his naivety. Otherwise, even if I took advantage of his trust to launch a sneak attack, I probably wouldn't have been a match for him at all.

Even after Uchiha Shisui had been successfully ambushed by Shimura Danzō, he had not truly lacked the ability to kill them in return. The main reason he had not continued fighting was that he did not want to attack Konoha's ninja.

Otherwise, an Uchiha who had activated Susanoo, even after losing one eye and suffering serious injuries, might not have been unable to deal with those Root members.

Next... Yamato is the target. This Wood Release Ninja is currently a member of Konoha's Anbu. Catching his trail will require some methods.

After pondering briefly, Uchiha Shūichi thought of someone.

Aside from the Third Hokage, the only person who should know Yamato's current information is Hatake Kakashi, the man who pulled Yamato out of Root!

Perfect. Hatake Kakashi also has a Mangekyo. Whether I use it against Uchiha Obito or test whether I can use Susanoo, I have to get my hands on it.

Uchiha Shūichi estimated that the possibility of activating Susanoo using Hatake Kakashi's Mangekyo was extremely small. Leaving aside that they were the eyes of two different Uchiha, they were both left eyes.

Eye transplants did not require concern over left or right. Whether it was a left eyeball or a right eyeball made no difference. Even transplanting a left eye into a right eye socket would still allow it to function normally.

But activating Susanoo probably still required both a left and right eye. Besides, combining Uchiha Shisui's eye with Uchiha Obito's eye in Uchiha Shūichi's sockets made the possibility of activating Susanoo negligible no matter how he considered it.

But that did not stop Uchiha Shūichi from taking that Mangekyo. Even without considering Susanoo, an ability like Kamui was an extraordinarily powerful one-shot kill technique. Not to mention that Mangekyo could also restrain Uchiha Obito.

Compared to the already decayed Konoha Village, Uchiha Shūichi was more wary of Uchiha Obito. That man was the true mastermind behind the Uchiha Clan's destruction.
