After a long time of digging, Kai found an artificial cave.


    ''It seems it was dug by some kind of creature. Maybe that creature has the fragment.''


    Kai manifested a sword and went inside the cave.


    The interior of the cave was no difference from the outside. As he went deeper, Kai realized that it didn''t seem like a cave; it was more like an entrance to something else.


    After walking inside for a long time, Kai finally saw the other end of the cave.


    "Why is there light at the end?" Kai found the light at the end to be suspicious.


    He used his Will Power to manipte the Darkness Law to reduce his presence. Kai carefully walked towards the new entrance without making a sound.


    Kai tried peeking inside the entrance, but he didn''t find any. He wasn''t able to see inside; there was something blocking his gaze.


    ''Let''s just go inside and check it.'' Kai decided to visit since both of his fragments pointed inside.


    Kai opened his mouth in surprise aftering inside.


    There was a hidden sand vige inside. A lot of small sands were moving here and there. The entire vige was covered by dunes.


    ''I didn''t expect a hidden civilization to be present here.''


    Kai didn''t think a civilization could survive in the Death Abyss due to its harsh conditions. But here, a hidden civilization survived and thrived underground.


    ''Maybe there are a lot of hidden tribes in this world.''


    Kai decided to meet with the people of this tribe since he didn''t feel the danger from this vige.


    After visiting, Kai found another surprise. There aren''t any people living here; the sand that he saw was the people living here.


    The sand here mutated and became some type of nature spirit.


    ''What is the reason for their mutation? And they have a high amount of intelligence.'' Kai began to ponder this situation.


    ''There may be some kind of treasure born here, and it caused the mutation. The fragment must have some kind of concealment ability to hide the existence of that treasure.'' Kai deduced the truth within a matter of seconds.


    Kai''s reasoning is correct; most heavenly treasures will grow in a safe ce. Their goal was to grow to a high level and get rid of their race''s limitations.


    The sand spirit didn''t do anything to Kai, they just inspected him and didn''t care about him.


    ''Why are they behaving weirdly?''


    Kai tried talking with them, but they didn''t hear him and continued their work.


    ''Why did I forget about their race?'' Kai soon realized his mistake.


    Sand didn''t have any sense, and the same goes for sand spirits. Kai also reduced his presence using the darknessw.


    Although their mutation must have granted them sense, it would not be like natural species that were inheritably born with senses.


    Kai didn''t reveal his presence to them anymore; he began to observe their behavior and study their character.


    After a long period of observation, Kai came to one conclusion.


    ''They aremunicating using vibration.'' It was a piece of information that Kai obtained.


    Kai tried to understand their vibrationnguage, but he didn''t learn anything.


    ''I should just explore this ce.'' Kai decided to leave this ce since he found nothing interesting there.


    Kai swiftly left the ce without anyone knowing. He began to search the ce and found a lot of simr viges to the previous ones.


    ''Just how big is this ce, and how did they build such a civilization?'' Kai became astonished after learning more about this ce.


    ''I want to acquire that treasure if it exists now.'' Kai suddenly made this decision.


    He knew the treasure that was capable of mutating the ce on such a grand scale must be at least Tier 4. But deep down, he knows that it wasn''t Tier 4.


    Kai personally saw a Tier 4 treasure, and it won''t mutate a ce on such a grand scale as this. Only Tier 5 treasures are capable of this.


    ''It seems I don''t have to find a treasure for Nirvana." Kai thought happily and began his search enthusiastically.


    After searching for a while, Kai found arge vige; no, it would be more urate to call it a city.


    ''I hope I can at least find information here.''


    Kai didn''t find any information about this ce, other than that the sand sprits are mutated.


    Kai went inside the city while hiding his presence. But as soon as he entered the city, Kai felt danger.


    ''I was thinking Why didn''t I encounter any bad luck? But, here ites.''


    Kai confirmed that there is a Tier 4 beast here in this city. He didn''t feel this type of danger in the vige since the highest-level beast there was Tier 3.


    ''I should act carefully and be extra cautious.''


    Kai wandered around the city and found nothing different. It was the same as in the viges.


    Kai didn''t visit the Tier 4 beast since he wasn''t confident enough to hide his presence from it. Although it didn''t make any sense, it could use its domain.


    After seeing the fight between the Whisper King and Thunder Ape, Kai decided to never underestimate any Tier 4 beasts.


    ''It seems I have no choice but to learn theirnguage.'' Kai thought bitterly.


    To obtain information, Kai had tomunicate with them. For that, he had to use vibration.


    It wasn''t hard for Kai since he could directly manipte electromaic energy, and using that, he could manipte vibration.


    The vibrations are produced due to the movement of electric and maic energy, so it is entirely possible to manipte vibrations using electromaic energy alone.


    Kai left the city and arrived at the nearest vige. He didn''t want to learn thenguage near the lion''s den.


    Kai used his Will Power to sense the frequency of the vibration in their conversation. It was hard to notice the change in frequency, but Kai had to do it if he wanted to learn theirnguage.
