In Feng Ye's view,
given his current level of strength, if he trained the Eight Inner Gates to the Fifth Gate, he should reach the peak of Kage-level strength.
If he reached the Sixth Gate and raised Time Acceleration by another level, he would surpass the Kage level!
Feng Ye had read some novels before that divided the levels above Kage into Super Kage-level and Six Paths level. In his view, that classification was basically sound.
The strength displayed by Pain's Six Paths, whether in destructive power or other aspects, clearly surpassed the Kage level. Whether it was the Third Tsuchikage Ōnoki or the Third Hokage Hiruzen Sarutobi, peak Kage-level figures like them would basically be doomed to defeat if they encountered Pain's Six Paths.
Madara Uchiha and Hashirama Senju went without saying.
Even all Five Kage together would not be enough for him to fight with one hand.
Such strength clearly could no longer be defined as Kage-level. It was strength above the Kage level, and there was nothing wrong with defining it as Super Kage-level.
Judging by the boost the Eight Inner Gates currently gave him, once he reached the Sixth Gate, combined with Time Acceleration and Time Reversal, he should possess enough strength to crush Kage-level opponents.
Of course.
There were differences in strength even within the Super Kage-level. Madara Uchiha, with the Eternal Mangekyo Sharingan and control over the strongest tailed beast, the Nine-Tails, was still no match for Hashirama Senju.
So beyond the Sixth Gate, it was difficult to say what level his strength would reach. Feng Ye roughly judged that relying solely on the Sixth Gate of the Eight Inner Gates and Time Acceleration would probably still not be enough to defeat Madara Uchiha and Hashirama Senju. He would need to add Sage Mode
