After leaving the blood sea, Kai and Shark Head took a moment to rest. On their way back, he didn't encounter any danger, they didn't even see any other living creatures.
'Why is the blood sea so calm?'
Kai pondered while looking the red sky. He read in the book of the First Explorer blood sea is the most dangerous place in the entire Abyss World, not consider the dragon lair.
But he didn't even spot a single creature and even the blood contained in the sea water lost their concentration at the depth.
'Just how did the Naline King obtain his fragment?'
This was another one doubt of Kai. During the history he learned of Naline Kingdom from Dono family library, he didn't get any clue about the sudden appearance of another fragment. This was the mystery for Kai, but he had suspicion that another person was probably manipulating the entire scene.
