The Qiongzhou Island in the game was a utopia and it was also another strategic location that Ouyang Shuo planned for.
After the game map was expanded 10 times, the size of the Qiongzhou Island reached 350 thousand square kilometres, bigger than even Lianzhou Basin. North of it, the Qiongzhou Strait intersected with Lingnan, west of it was Guangxi and Vietnam, east of it was the Yizhou Island, southeast of it were the Philippines, Malaysia and Brunei.
During the Ming Dynasty, the imperial court set up the Qiongzhou House on the island and split it into 3 states and 10 counties.
Out of the 3 states, Danzhou was to the west of the island. In terms of geography, it was closest to the Lianzhou Basin. Hence, in theory it would be a good place to come ashore.
Ouyang Shuo instead turned his eye to Yazhou at the southmost area of the island. Compared to Danzhou, it was more suitable to be used as a military port.
Yazhou would be the best base for Ouyang Shuo to use to enter the ocean.
