Flying Swords of Dragon Gate(2011)

Three years after the infamous Dragon Inn was burnt down in the desert when its innkeeper Jade vanished. A new gang of marauders had taken over - innkeepers by day and treasure hunters by night. The inn is the rumoured location of a lost city buried under the desert, and its hidden treasure would only be revealed by a gigantic storm every 60 years. The gang used the inn as a front to locate the lost treasure.
