This island was clearly not suitable for human habitation, as there were no signs of anyone ever having lived there.
But Shu Guan felt that even though the island's scenery was beautiful and it was so close to the coast, it might never have been discovered by anyone before.
Because when he was coming over, in the ocean ten-odd nautical miles away from this island, he discovered a peculiar undercurrent. This undercurrent circled the island, and its strength was immense; to give an idea of how strong, let's just say that even today's steamships, if less than ten thousand tons, would be deviated from their course once they entered the undercurrent.
And beyond ten nautical miles, even when the weather was clear, it was very difficult for mortal eyes to spot this small island, which was only two to three meters above sea level.
