The giant door shook more and more violently, and the gap was slowly widening, but no matter how Zhuge Yu increased the energy output, the door remained in that state, unable to open any further.
After more than ten minutes, Zhuge Yu's spiritual energy was nearly exhausted, sweat beads forming on his forehead, forcing him to stop activating the array.
The icy blue energy ball dissipated, the shaking of the giant door gradually subsided, and the gap closed again, returning to its original state.
"Can't do it." Zhuge Yu put away the array plate, shaking his head helplessly.
Everyone fell into silence.
Seeing the treasure vault within reach, yet stopped by this door, the feeling was truly frustrating.
Qin Tian stared at the runes on the door panel, his brows knitted tightly. Suddenly, he remembered something, a glimmer of light flashing in his eyes.
"Let me try."
Qin Tian's voice broke the silence, and everyone turned to look at him.
