Green chakra erupted from Naruto's body with a thunderous blast, its density and scale far surpassing Might Guy's state when he opened the Seventh Gate—by dozens of times, at least.
The principle of the Eight Gates Released Formation was to remove the body's internal restrictions on chakra, allowing all that suppressed power to be released in a short time. How much chakra the user possessed and how much impact their body could withstand determined just how much power the Eight Gates Released Formation could ultimately unleash.
So even when opening the same Eight Gates, the difference between users could be enormous.
In the end, this forbidden technique simply released the chakra stored within the body without restraint. When Might Duy opened the Gate of Death, he kicked the Seven Ninja Swordsmen into disarray; when Might Guy opened the Gate of Death, he had nearly crippled Six Paths Madara with a single kick.
The difference in their performance was not due to any difference in the Eight Gates Released Formation, but because the total amount of chakra in their bodies was on entirely different levels.
At this moment, the chakra erupting from Naruto resembled a raging demon, roaring madly toward the Hidden Cloud Village army. It was clearly only the Seventh Gate, yet the pressure it brought had already completely surpassed Might Guy's Eighth Gate.
That was why Might Guy always said that Rock Lee and he were geniuses of hard work.
True geniuses, on the other hand, found it difficult to master the Eight Gates Released Formation.
The stronger one's chakra, the stronger one's body had to be to endure that power. The chakra within underachievers like Might Guy and Rock Lee was only one-tenth that of ordinary geniuses, perhaps even less. After opening the gates, the backlash they endured
