As Zhao Tian followed Yan Zijin, the wind brushed through the trees around them and soon both of them reached the cave.
The entrance to the gravity cave loomed ahead, carved into the side of a jagged cliff.
It radiated an oppressive energy and Yan Zijin paused at the entrance as she turned her gaze to Zhao Tian.
"Remember," she said, her voice as cold as ever, "the gravity inside the cave increases in layers. I'll only guide you up for some layers. Beyond that, it's up to you."
Zhao Tian nodded, "Yes, Master."
Her lips curved into the faintest hint of a smile. "You'll need more than your best."
She stepped inside without another word, and Zhao Tian followed.
The air inside the cave was dense, pressing against his chest with every step.
The further they walked, the heavier it became, as if invisible chains were over his shoulders.
By the time they reached the first layer, Zhao Tian's breathing had already grown heavier.
