You must go back to the time period 1387 AD and climb the houses to find a man in blue robes. You tell him you have his salt rocks and you complete the time period.
there is no pile of bricks...
take it to the vikings and climb up the mountain till u get to the cave with rocks in front of it, click on the pile of rocks, and the gunpowder will blow the rocks away.
It depends on which wall it is. Such as on the island Time Tangled where you have to get through the pile of rocks at the top of the mountain next to the viking ship. to get past that wall, you need to find the barrel of gunpowder in a different time period, then go back to the rocks and use it.
Jump on the rocks.
It means that the item is used automatically. For example, the gunpowder cannot be used anywhere but in 831 AD. Click the pile of rocks in front of the cave to explode it.

You go to the great wall of china and the gun powder should be there then go to the second place on your compass once you get there go to the pile of rocks and click on it. the Golden Vase should be inside at the bottom of the cave.
