After solving the Fox Immortal's riddle, Yun and Ling Shan experienced a significant surge in their cultivation levels. They stood in the cave, sensing the purer aura emanating from each other, sharing smiles filled with anticipation for the future.
The Fox Immortal's voice resonated once more in the cave, tinged with approval. "You've done well, but the secrets along the path of Immortal Cultivation extend far beyond. Beneath the Yellow Sand Ancient Land lies an ancient secret, where you may find the answers you seek."
Determination flickered in Yun's eyes. "Fox Immortal, we appreciate your guidance. Ling Shan and I will journey to the Yellow Sand Ancient Land to uncover that hidden secret."
Ling Shan grasped Yun's arm, her eyes shimmering with adventure. "Yun, we're in this together. No matter what challenges come our way, we'll face them as a team."
Leaving the valley behind, the duo embarked on their quest to the Yellow Sand Ancient Land. It was a harsh terrain, plagued by relentless winds and sandstorms, rumored to hold countless relics and secret tomes of Immortal Cultivators, yet shrouded in peril.
After enduring several grueling days of travel, Yun and Ling Shan reached the Yellow Sand Ancient Land. Stretching endlessly before them was a golden desert, bathed in the scorching sun, with sand dunes rolling as far as the eye could see. They cautiously traversed the desert, searching for any hints.
During a fierce sandstorm, Yun and Ling Shan stumbled upon an ancient ruin buried beneath the yellow sand. The entrance, veiled by a weathered stone door inscribed with cryptic runes, appeared to be an ancient seal.
Drawing upon the wisdom bestowed by the Fox Immortal, Yun meticulously deciphered the runes on the stone door.
