The Sea Shark King returned on the eighth day, and with him, he brought a sea chart made from shark skin that covered a radius of two thousand nautical miles.
The scope of the chart was vast, marking out every island, like stars sprinkled across the sky, including several significantly larger than Crescent Island.
Tang San directly gave Sea Shark King Louis five Sea God Array Discs as a token of his gratitude. He knew full well how precious this sea chart was.
In the Endless Blue Ocean, where the Sea Clan roamed wide, drawing up such a chart through exploration was as difficult as reaching heaven, not to mention the amount of Time it would take.
