<h4>Chapter 639 Mysterious No Return Zone</h4>


    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 assimte the information he had gotten from the blood glyph, 23 days had passed since thest 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.


    After confirming that there wasn''t any danger, he felt relief. Suddenly, blue energy gushed out of his body before turning into a water glob, washing away the blood on his face. He then used the fire aura to dry himself and felt refreshed, just like he had taken a bath.


    But he didn''t open the cursed immortality this time, for he was reaching the destination, and he wanted to be alert at all times, especially after finding that he had been out for over twenty days just by touching the blood glyph.


    Now that he knew what he had to do, he was no longer in a hurry to explore further. But it was too dangerous for him to fall unconscious while he was still traveling the star ocean and this close to the legendary key.


    Jacob sat on the captain''s chair and again fell deep into thought about the information, ''I seem to have a closer connection with my blood after touching that glyph. I can''t wait to unravel it''s mysterious, especially the crimson infinity symbol, that I can''t get out of my mind...''


    However, when night fell and the surroundings turned pitch dark because of the fog, Jacob suddenly felt uneasy in this eerie silence. He was confused since everyone seemed to be fine a moment ago; now, all of a sudden, he started to feel uneasy.


    Nheless, he didn''t dare to ignore it, for he had learned a lesson in the past.


    He quickly took control of the ship and started to descend towards the ocean from a 100,000-meter altitude!


    But Jacob noticed that as he was going down, the fog was bing thicker, and the atmosphere was bing colder. That uneasy feeling had almost vanished.


    "Alert! There is a solid surface at a 4000-meter distance!"


    ''What, surface, not ocean? Just where in the world is that bastard hiding the key?'' Jacob was astounded as he quickly decreased the speed, and the next moment, he opened the eyes of judge!


    Instantly, the mist ahead of him vanished without a trace, and he could finally see the ground, which was actually a mountain peak!


    Then Jacob instinctively looked up, and his heart palpitated the next moment because right above him, a few hundred meters ahead, he saw a huge dark mass floating there, like a flying ind!


    But the particles emitting from it were purple, a color that Jacob hadn''t seen before, and by just looking at it, Jacob felt mortal danger. He finally understood why he was having that feeling!


    ''Just what in the hell is that thing? Could it be a flying ind? But it''s impossible sincends don''t emit those color particles. Don''t tell me that is a living colossal creature, and the mist seemed to being from it!''


    Jacob didn''t dare to be careless, nor was he curious to go there and seek his own death out of curiosity, so he hid his aura as much as he could and desperately descended toward the mountain.


    ''If I''m not mistaken, that bastard hid the legendary key in some No Return Zone since they are the safest ces, and people seldom enter them. To my knowledge, there are only four famous No Return Zones that no one dares to go deeper into, or they will never return. But which one is that?'' Jacob wondered grimly.


    The ship finallynded on top of a snow peak, around 50,000 meters above ground. The winds were freezing.


    But Jacob didn''t care about the cold as he quickly exited the ship,nded on the frozen snowy surface of the mountaintop, and quickly stowed away the ship. He was keeping an eye on that humongous thing in the sky while wishing he wouldn''t get noticed, and he finally felt huge relief when he safelynded.


    Now, he felt more at ease since he was far from the danger in the sky, but the surroundings were still filled with thick, cold fog. But he wasn''tpletely blind and could clearly see around a hundred meters with his eyes.


    Furthermore, the white particles in the fog were now even denser, and he finally understood what they were, ''This is most likely the Icy Magic Energy that has materialized in the air. Just how dense is it? I guess I have no choice but to head towards the location on foot since it''s not too far and probably hidden somewhere in this ce.''


    Jacob had no choice but to activate his star watch again. The moment he did, he found many messages and ignored them all. He quickly activated the marked map and, with a flying disc, descended the icy mountain and headed east.


    "Roared!"


    "Growled!"


    Jacob suddenly heard ear-piercing roars not far away from his position and then powerful sonic booms, making the fog churn and ripple in the vicinity.


    ''Magic beasts fighting each other? Furthermore, I can feel their pressure from this far away, and they are not at the Unique Rank!'' Jacob''s eyes shimmered, as he never expected to encounter Beyond Unique Rank Beings in this ce.


    ''I never had three steps of legend rank meal before, and since they are fighting with each other, I can just finish them off…''


    Jacob didn''t dy and sneakily made his way towards the source of the uproar!
