Ten minutes after the Cooter Clansmen on Roit Island left to inform the Cooter Clan, the Sumatra Ship arrived ashore. Inala got down and began to set up the operating table.
Roit Island had a massive population of Free Humans, numbering fifteen thousand. It would take him close to three days to extract the Spirit Containers of them all. Of course, Inala didn't have that much time.
Hence, he had to be quick about things. Until now, he had only extracted Spirit Containers from Free Humans on Fral Island. There were more than ten islands where the Free Humans had been fed the Mystic Mist Elixir.
But as all of them were more or less the size of Leh Island, he could be done with each in a matter of hours. Therefore, he could hit those islands, exterminate the Cooter Clansmen stationed there, extract the Spirit Containers from the Free Humans and make his escape.
Before the Cooter Clan even notices what is happening, Inala would have long left the island.
