Li Shiming discovered a fourth-grade top flying boat in Jiao Xian the Great Cultivator's soul crystal ring.
Perhaps due to the strong cultivators he's encountered at the Cloud Island Sea, in the short time he's been there, he has acquired two fourth-grade top flying boats and a considerable number of fourth-grade upper stage flying boats.
It's worth noting that while he has quite a few fourth-grade top flying boats, they were obtained over long years of battling numerous formidable enemies as spoils of war.
Moreover, most of those fourth-grade top flying boats have ties to Great Powers, which made him reluctant to use them in the Cultivation World before now.
However, the two fourth-grade top flying boats he got from the Cloud Island Sea have nothing to do with Great Powers.
In his view, this might be related to the abundant resources of Cloud Island Sea, coupled with the necessity of using flying boats for long journeys, thus resulting in more fourth-grade top flying boats.
