"All Lightning Release chakra, release!" A shouted, releasing his own chakra without reservation. Most of the people present had used this Lightning Release Formation before, so there was no need for significant coordination. Releasing the Lightning Release chakra simultaneously was sufficient.
As the one overseeing this Lightning Formation, A was responsible for gathering all the Lightning Release chakra released by everyone to a single point and then unleashing the most powerful Lightning Release technique.
Upon hearing this, the other Jounin exerted every ounce of their strength, not holding back their chakra at all, disregarding the subsequent weakness after expending all their chakra.
"Ryoha, face our Kumogakure's strongest combined Lightning Release technique, Combination Lightning Release: Thunder God's Furious Wrath." This move could be considered A's trump card, similar to some Sharingan techniques, using the name of a deity to label the technique. This indicated the immense strength of this Lightning Release secret technique.
Even before the strongest Lightning Release technique, which combined the power of over a hundred Jounin and A himself, appeared, countless thick lightning bolts flickered. The surrounding land and massive rocks were split by the sudden surge of lightning, causing a flurry of debris and dust.
"It's truly formidable. Well then, I'll let you see my move. Dark Release: Black Gaia Force!" Ryoha, observing A continually forming a huge lightning ball nearly 200 meters in diameter, suddenly had a flash of inspiration for this move.
He borrowed the inspiration for this move from an anime he had watched in his previous life as a young boy called "Digimon." In it, there was a very powerful move used by one of the immensely strong Digimon called "BlackWargreymon," and Ryoha developed this technique based on its principle and name.
Sometimes, overly complicated ninjutsu couldn't showcase their maximum effectiveness in battle. Instead, it was the techniques with relatively simple principles, but requiring extremely skilled chakra control and proficiency in ninjutsu, that proved to be the most effective. Techniques like the Tailed Beast Bomb, Rasengan, Chidori, and so on were the best examples. The principles were not complicated; it was just that very few could learn them.
In Ryoha's move, the principle was similarly simple, but executing it to release this move instantly and achieve its instant completion was something only Ryoha could do. It required extremely precise chakra control, mastery of ninjutsu, and high proficiency in using them. Also, the necessary energy for releasing this move was the dark energy of Dark Release, which only Ryoha possessed. In other words, nothing was lacking.
Of course, being able to instantly complete these techniques based on the actual needs of the battle and inspiration, especially since he had already developed Dark Release, what was needed now was to maximize the effectiveness of Dark Release in actual combat with this move and its usage. Ryoha also found the name "Black Gaia Force" fitting, so he used it as the name for this move.
Ryoha placed his hands in front of him, and a light sphere with a central dark-red color and surrounded by black appeared between his hands. As Ryoha raised his hands, the sphere, dark-red at its center and black at its periphery, continuously expanded and took shape. In the end, it surpassed the enormous lightning ball created by A, with a diameter of over 300 meters.
(Black Gaia Force can increase in size and compression intensity based on the output of dark chakra.)
"What kind of monster is this?" Whether it was A or the other Jounin from the Kumogakure, they were all horrified. The strongest ninjutsu they released by uniting so many people, this lightning ball with a diameter of over two hundred meters contained an extremely vast amount of compressed lightning chakra. Even after compressing it to the extreme, it could only maintain a size of over two hundred meters, meaning that even at its most compressed, it was still enormous.
From this, one could see just how terrifying destructive power was concealed inside. In front of this lightning ball, Kumogakure's colossal Lightning Release jutsu was simply like a newborn baby compared to a battle-hardened special forces soldier.
However, they felt the same aura from the Black Gaia Force in Ryoha's hands as they did from the lightning ball they created. In other words, the power of the Black Gaia Force was at least on par with the enormous lightning ball they all created together.
"We might lose the individual, but we won't lose our formation. We must maintain our momentum; believe in your own strength and give it all you have." A's voice calmed the other Jounin's shock. They had given their all. As A pushed both hands upward, the Thunder God's Furious Wrath, rising from below, truly carried a divine-like fury as it rolled towards Ryoha.
"Haha, A, even if you all attack together, you won't be my match." Thunder God's Furious Wrath? Using the name of a deity as a finishing move was impressive? Little did they know that Ryoha's Black Gaia Force also contained the name of a deity.
Gaia was the name of the most powerful mother of all gods in Greek mythology, which Ryoha knew. Ryoha hoped that this move's name was just right because it had these two words in it. As a name for this move, Black Gaia Force was quite imposing, and this name paired extremely well with the move. It would be a waste not to use it.
Two enormous energy balls, capable of easily shattering everything, collided in mid-air. Initially, visible air fluctuations spread out in concentric circles, causing anything touched by them, whether it was the surroundings or lakes, to be forcibly pushed away.
Simultaneously, a continuous rumbling, akin to thunder, accompanied this. Blinding rays of light intermingled, constantly blossoming. For a moment, the two energy balls were locked in mid-air, seemingly evenly matched.
"He's just one person, and we have so many. I don't believe we can't overpower him." A was the first to use a technique similar to the Eight Inner Gates. His body was strong enough that even using the Eight Inner Gates, he could easily open up to the Sixth Gate. However, his technique was not the Eight Inner Gates, but the principle was the same—temporarily boosting one's strength, and the others followed suit.
However, because of A's instructions, they didn't go all out, using life-threatening secret techniques, but instead used techniques to temporarily boost their strength. The side effects were not significant; they would completely recover after a few days of rest without any lasting repercussions.
However, even so, the sudden and substantial increase in strength of so many people was extremely frightening. Coupled with the effect of the Lightning Formation, they outputted their Lightning Release chakra without any reserve. It transformed into a thick and long streak of lightning that struck directly at the lightning ball. The lightning ball, just released a moment ago, seemed to be continuously bolstered, becoming increasingly enormous, and even had a tendency to surpass the Black Gaia Force.
