This chaper shows once again that Oda himself is the fraud. He keeps milking that Conqueror's Haki as a story hook over and over. So apparently the secret to overcoming the bothersome recovery is just to use Conqueror's Haki, pure and simple, and Luffy supposedly never considered using it in his fight against Saturn and the other Gorosei, even in G5, despite being very angry at the start and wondering about how to harm them.
And like Zoro against King having to "learn" the secret of the power of Conqueror's Haki, despite having been shown to use it about 2 times in the fight against Kaido already, and Kaido even telling him, Oda STILL uses it to create massive fake tension after all this time, for both Luffy and Zoro, despite Luffy having been introduced as an expert of it even before G5.
This suggests that Oda had intimidated one of the leading Japanese OP theorists Yuderon out of his activity (and maybe even symbolically shot him in the head in the form of Vegapunk's Shaka?) simply because he runs out of genuine mysteries and surprises.
