Seems like your stubborn buddy either way splitting the ice island is his greatest feat while zoro did not go all out and just received a hax sword .
I think you missed the point that I
only talked about feats which were shown so far in the manga...
Once again: Chinjao's is more impressive, he split an island.
Honestly, if ISDS is the strongest shown attack in OP, many VS Battles sites would put OP characters on Mountain lv+ instead of Large Island lv/Small Country/Country Lv, lol.
I've never excluded the possibility that Zoro could show those feats as well, especially with Enma. Therefore, just re-read my posts again, mate...
So since he was already stronger then him in dressrosa that difference is expedited now
Well, at least there's the possibility that Zoro or other characters on his level can show such feats as well; they do not even have to since their AP would match Chinjao's island splitting attack anyway.
