What should he do?
The instant Uchiha Yue's Falling Moon Style Secret Technique: Blade Waltz came to a stop, even Uchiha Yue himself had no idea what to do next. Surrounded by countless Kirigakure ninja, he found it difficult to so much as move a finger. With his mental energy completely exhausted, even a quasi-Kage-level expert like Uchiha Yue could not deal with a single genin-level Kirigakure ninja. Much less when so many elite jonin-level Kirigakure ninja stood before him.
With no other choice, Uchiha Yue finally thought of a solution that was barely a solution at all.
That solution was to use Monster Ido's ability to absorb the mental energy of one—or even several—Kirigakure ninja, replenishing his own mental energy that way!
Without question, this was the method Uchiha Yue least wanted to use. If he used Monster Ido's ability to absorb the mental energy of multiple Kirigakure ninja, his body would not only suffer severe damage while absorbing that mixed, impure mental energy. Absorbing too much impure mental energy might even contaminate his own.
If that happened, Uchiha Yue's impure mental energy would indirectly weaken his strength.
After all, once mental energy had been cultivated to Uchiha Yue's level, what mattered was no longer its quantity, but its quality.
To give a simple example, Uchiha Yue's mental energy had originally been pure, like an elite ninja unit. There might not have been many members—perhaps only four or five ninja—but every one of them possessed Kage-level or quasi-Kage-level strength. Such a ninja unit was undoubtedly far stronger than an ordinary one. Even a ninja unit made entirely of elite jonin could accomplish nothing against a Kage-level unit.
However, if Uchiha Yue absorbed too much impure mental energy, his mental energy would become like a ragtag ninja force. Even Uchiha
