After the last and main guard disappeared, all his things fell on the ground. Among the things was an old-looking key.
The Luyao were an old school clan - they kept things simple. For example, when it came to keeping their clan's gold and treasures, they kept it behind the most secured hidden chamber of the fort. They called it the treasure chamber, and only two people kept the key - the main guard and Congming.
The main guard was one of the most reliable members of the clan. Congming could not be bothered every time anyone needed gold or silver for some trade for the clan, so all they needed was permission, and the main guard could provide them with the gold and silver the clan needed.
Wuyi went deep inside quietly. After walking through a few more narrow chambers, he came up to a wall in the deepest part of the fort, a solid thing that looked simple but was very carefully built.
