This surprised Ye Feng, as he hadn't expected the existence of Holy Crystals within the Sword Palace.
In no time, Ye Feng and Ling'er moved everything from the Sword Palace's treasure vault.
Ling'er looked at Ye Feng with satisfaction and said, "Let's go, there's nothing here left for us…"
"No! There is still one thing we haven't taken!" Ye Feng said loudly, then proceeded to the deepest part of the Sword Palace's treasure vault, where there was a cylindrical stone platform with a protruding button.
Ye Feng pressed the button, and immediately the ground trembled, revealing a large door.
An underground passage appeared before Ye Feng and Ling'er. Seeing it, Ling'er asked with confusion in her eyes, "What is this place?" Ye Feng responded calmly, "We'll know once we go down to take a look."
Then, Ye Feng and Ling'er entered the underground passage together and began exploring.
