That's exaggeration. Sure, if he went on rampage for several days with awakened powers, he might lay waste to the surface of the planet. That is no combat feat however. It's not even useful. If Whitebeard would destroy the island he is standing on, he would fall into the sea and drown. Sword lethality of a swordmaster who turned his blade black is more devastating for combat.
What would Ryuma do?
Fighting fodders and protecting wano?
Killing a mere dragon?
Stop living in empty hype

Kawamatsu being below but above Vets : Izo, Kinnemon & Kiku
Imagine thinking top retainers are around p1 or WsW lol
