When you have the barrel of gunpowder from the Great Wall of China (1593 AD), you can just click on the rocks at the cave (831 AD) and they will be blasted away.(There is no USE on the gunpowder.)
to use the gunpowder go to the viking time and go to the cave and click on the rocks and BOOM! the caves open.
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.
The gunpowder from the Great Wall of China (1593 AD) is used to blast open the cave at 831 AD, which is blocked by rocks. (see related question)
