The spawn is in a jungle which borders a desert biome where all of the temples can be found. By just a little bit of walking you will find three temples and a village which combined have lots of iron ingots, gold ingots, diamonds and emeralds.Just walk straight ahead and you will find the first temple. It’s literally in front of spawn.
To find the chests in the temple go to the center in the temple and find the colored blocks (orange & blue) and destroy those to find the opening down to the treasures.
The second temple lays a little to the right behind the first temple. It has definitely the best loot.
The third temple has probably the worst loot but it still has some valuable ingots which are always welcome.
The village is located behind the third village. One part of the village has been generated in a flat landscape while the other has been generated on top of a sand hill.
