First, let me apologize. This time, it really was my mistake. The main issue was that I mixed up Evening Elephant and Daytime Tiger. In the Original Work, when Madara clashed with Might Guy, Might Guy first used Evening Elephant to break Madara's horn and injure him. Only afterward did Evening Elephant's kick nearly kill Madara in his Ten-Tails Jinchuriki state. What I got wrong was attributing the damage caused by Evening Elephant to Daytime Tiger.
Chapter 502 was written three days ago. At the time, I did have a slight doubt, but first, I wrote it right after getting off work, so my mind was a little foggy. Second, I was lazy and didn't go back to reread the Original Work. I stubbornly assumed I was right and wrote Daytime Tiger as if it had the power of Evening Elephant. That was why there was a description of the Seventh Gate's Daytime Tiger shattering a complete Susanoo.
That was my mistake. I apologize.
The readers were right. Seven Gates Guy should only count as a Strong Kage. This is still nine years before the Great War, so he can only be considered slightly stronger than an ordinary Kage-level fighter.
At most, he could destroy a third- or fourth-form Susanoo. He could not threaten a complete Susanoo, at most leaving a few cracks in it.
From the First Gate to the Seventh Gate, it was merely a regular stacking of power.
Eight Gates Formation was the one-time, true explosive qualitative transformation.
I'll revise some of the descriptions as appropriate, so they won't seem quite so outrageous.
I hope all you readers can forgive me.
