Hao Xuan stood in front of the vault door in the middle hallway.
'I hope they're still there.'
He closed his eyes and the information about the vault door slowly came up.
With his index finger outstretched, Hao Xuan started circulating his Qi. All the Qi slowly circulated towards the finger and it started to light up. The bone and veins in the finger could be seen with the naked eye as the tip started glowing.
*HMMMMM*
A humming sound came from the door when he touched one of the symbols on the upper right corner, lighting it up as well. Hao Xuan did this more than 64 times. Tapping gently on one symbol after another, by the time he was done, the symbols formed a web that looked like a giant face from afar.
*Clank*
With a light sound, the door was unlocked and pushed open on its own. It was more than seven meters thick, made from the same black metal all the way to the other side.
