Sorry, I'm too lazy to use Corel Draw or other applications so I just use paint to make a simple map
The blue triangle is where we start this stage's mission.
The red dots are the locations of the jades that must be destroyed.
Inside building B1 it shouldn't be difficult to find it.
For the outside area, the first jade is on the small bridge in the starting area and the second jade is above the door which requires us to destroy all the jades.
for the jade in the building which is located below the map. the first one is in the first room attached to a pole. the second is in a room that has a long red gas cylinder. the third is in a room that has a stone monument with an eye carved at the top. and the fourth is in the room that has stairs.
I myself haven't finished this stage because after passing through the door with the jade requirements suddenly my laptop got a d3d lost error so I decided not to continue with the stage..
