47 Linglong Chess Game!

The interior of the pyramid was a triangular room, and a dim light illuminated the hollow space. 

At the center of the room, there was an inverted pyramid that looked like a tabletop, and a chessboard was lying on top of it. 

Other than the inverted tabletop, there was nothing else in the room.

Before Lin An could figure out the purpose of the chessboard, a deep voice rang out and reverberated in the hollow space.

"If you can solve this exquisite chess game, the treasure vault will open, and you will choose three treasures at will!"

"However, failure will lead to immediate death!"

After he heard the ethereal voice, Lin An felt calm.

He now understood the rules of the pyramid.

As long as he solved the exquisite chess game, and passed the test, he would naturally acquire the key fragment.
