64 Xiao Hua's Mission

After walking up 20 flights of stairs, Yuan and his small group finally reached the 21st floor. On this floor, there existed only three doors made of stone that were evenly distanced from each other and a stone tablet right beside each door. Two of the three stone tablets already had a key inserted into the hole, signaling that it was already occupied.

Therefore, Yuan and the others walked to the stone tablet that had an empty keyhole.

After inserting the key into the keyhole, the stone door began to tremble before it started opening. However, it was unlike any normal door, and it opened by levitating off the ground.

Once they walked into the empty room, the stone door closed itself, sealing them inside.

A few moments later, the empty room began filling with rich and dense spiritual energy, and a large drawing resembling a magic circle appeared on the floor that spread throughout the entire room.
