Tang Lan took the most crucial yet shattered crystal fragment.
This thing was probably an energy core. He could take it back and let several Grandmasters from Shrek Academy's Soul Tool Department study it. Perhaps they would make an unexpected discovery.

After Bell pointed it out, Tang Lan began paying attention to their surroundings as well, and soon heard the gentle sound of flowing water.
The three followed the sound and quickly discovered an underground spring in a corner on the eastern side of the cave.

Tang Lan pointed toward another corner as he explained.
Upon hearing this, Bell and Long Yao immediately went over to inspect it. Before long, Bell cried out, "There's also a metal box left behind by that guy here.
