The nearly black lightning surrounding Thunderstorm radiated a suffocating, sinister pressure, as though it devoured even light. Beneath his feet, the ground cracked and blackened inch by inch under the energy spilling from him. This was no longer ordinary Lightning Release, but a mutated energy mingled with the Sacred Lord's source darkness, filled with corruption, decay, and pure malice.
"Can you feel it? This is Lord Sacred Lord's true blessing! Beyond any mortal ninjutsu... Abyssal Power!" Thunderstorm's voice was warped and fanatical. He slowly raised his arms, clad in pitch-black Lightning Armor, and even the air around him seemed to grow thick and heavy.
Kakashi's feint with Lightning Blade struck the black Lightning Armor, but produced only a tiny spray of sparks before a stronger recoil knocked it away. A bone-chilling cold and numbness spread through his arm. His Sharingan clearly caught a wisp of black vapor trying to creep up along his Lightning Blade! He immediately canceled the technique and retreated, his expression graver than ever. "Watch out! His energy has undergone a fundamental change. It now has extremely powerful properties of both mental corruption and physical corrosion!"
"Naruto!" Ling did not turn, but his voice carried clearly to Naruto, who was still struggling against the beastly instincts within him. At the same time, Ling pressed two fingers together like a sword, gathering highly pure senjutsu chakra imbued with soothing natural fluctuations at their tips. He touched Naruto's forehead as swiftly as lightning. "Calm your mind!"
That cool, pure strand of senjutsu energy flowed like sweet dew into Naruto's chaotic sea of consciousness. The savage red chakra reacted as though doused with cold water, churning violently before it was temporarily suppressed. The scarlet faded from Naruto's eyes, restoring a trace of clarity, but he was still panting and pale.
