Mysterious No Return Zone

Jacob had left the flying ship on autopilot and activated the warning mode if anything untoward showed up. The warning he just received was from the flying ship interface, so he quickly entered the control room and saw that the flying ship was now flying into a fog-filled sky. 

Furthermore, the fog was filled with faint white energy particles, making him wince his brows. 

'How long I'd been out?' 

Jacob frowned as he quickly scanned the map on the ship. He was surprised to see that, including the three days it took him to assimilate the information he had gotten from the blood glyph, 23 days had passed since the last time he opened the Immortal Chapter. 

Now, he was very close to the location, and this misty area seemed to be where the legendary key was hidden.
