After closing the stone door, Chu Feng could still sense the presence within the passageway. Only after confirming that Su Mei and the others had left did he feel reassured and head to the edge of the cliff.
Climbing down the vines, Chu Feng began to descend towards the sea of fog below. When he neared the sea of fog, Chu Feng extended his Mental Power, only to discover that there was a strange gas within the fog that could interfere with his Mental Power, making it impossible to penetrate.
Especially after entering the sea of fog, the hazy white expanse blocked his vision; even with Chu Feng's strength, his visibility was less than ten meters.
Fortunately, after descending dozens of meters in the fog, he finally reached the bottom. Although the fog remained, the feeling of stepping on the rocks calmed Chu Feng's anxious heart.
Shua, shua, shua.
Chu Feng took out the Spirit Realm Compass, and it immediately radiated brilliant light. His visibility instantly increased several times. Honestly, the light from this thing was truly peculiar—it seemed to pierce through the fog. It was indeed a treasure for seeking relics.
"It seems this place is truly fraught with danger."
Looking at the indications of the Spirit Realm Compass, Chu Feng quickly knew the direction he needed to go, but at the same time he also knew that countless deadly threats lurked all around him; one careless mistake and he would die.
It was fortunate that he had the Spirit Realm Compass in hand; otherwise, entering a place like this with his strength would have been a perilous venture, and even nine lives might not be enough.
Holding the Spirit Realm Compass, Chu Feng walked through this fog-filled underground space. He could faintly hear the roars of Fierce Beasts in the distance, as well as extremely eerie cries, even the painful wails and calls for help from people.
Moreover, these sounds only grew denser and closer as he went deeper, until eventually, Chu Feng could even see corpses that had just been devoured.
Sensing a powerful oppressive aura, he could hear some Fierce Beasts walking and roaring not far from him. They were Ninth-rank Fierce Beasts, even stronger than Spirit Martial 9th Stage experts.
It was said that Ninth-rank Fierce Beasts were already the strongest level among Fierce Beasts, and stronger than Fierce Beasts were intelligent demon beasts.
Although demon beasts do not kill indiscriminately, their cultivation ability is far above that of Fierce Beasts, and they possess intelligence not inferior to humans, or even stronger. Most importantly, demon beasts are very strong; they are born strong, carrying the noblest bloodline among beasts. It was said that even a newborn demon beast was innately at the Yuan Wu Realm.
Powerful demon beasts could even speak human language and even transform into human form. Some demon beasts who disliked the deep mountains and forests would transform into human form, enter human society, and live a life like that of humans—truly living up to the word "demon."
This place was full of dangers, and thinking of the strength of the Elder of Void Flight when he was alive, Chu Feng had no doubt that he would catch a few demon beasts and throw them here, binding them in some place.
Fortunately, after carefully walking for a full hour, the thick fog ahead gradually thinned, and at last the clouds parted to reveal the sun, and he walked out of the fog.
"Phew, finally out."
At that moment, even Chu Feng couldn't help but let out a long sigh of relief, because the area in the fog earlier was like hell, and being inside it was extremely oppressive.
"Damn, just how big is this Elder of Void Flight's burial ground?"
Looking up, Chu Feng couldn't help but feel helpless; what appeared before him was not the treasure he had expected, but another deep passageway.
