Very well said, it literally ended, in fact, see how the Goroseis showed concern about Shanks, and even raised the hypothesis that world conquest may be something that the ambition of Shanks' conqueror's haki not aims for, however this may be precisely what Shanks may also be aiming, basically among the emperors Shanks is the only one so far, Kaidou wanted the world, Big Mom allying with him wanted the same, BB wants the same, Luffy's dream may include something like this or similar, WB was the "king of the sea", and Shanks can show interest just as he started to have an interest in the OP.
It's no wonder Kaidou called the government arrogant when they thought they could now stop them with the new seraphim.
