Heroic Force: The Awakening/Part 3 and finale

Jan illuminates the drawing: a man and jewels in cyan, red, blue, light blue, orange, purple, yellow, white, and white with black
Claire: These are ancient paintings.
Reddie: Do you think the alien wanted us to see this?
Jan: There are stairs over there, let's see where they lead. This place is thousands of years old; it must be an unprecedented discovery.
Claire: But are you guys sure about this?
Reddie: Let's just go, Claire.
Where are we even going? Jan turns on the flash, leaving the two of them blind for 5 seconds
Jan: I don't know, but it feels like we're crossing the mountain. They keep walking, Reddie runs ahead
Jan: Reddie, slow down! They catch up to him; Reddie is completely surprised and excited Jan: Have you gone crazy? She is surprised; the view changes to a beautiful place with a river, a stone bridge, and a temple Jan: It's like a secret garden! Reddie encounters a horned caterpillar that roars at him; he slaps it, knocking it to the ground Jan: Is that a temple over there?
Reddie: Yes, but it's closed.
Claire: Guys, let's go over there, I think it's a clearing, you need to see this.
Jan: Wait, Claire, why the rush? There are several different animals with horns, scales, dragonfly wings, etc. Claire: What kind of place is this, huh?
Jan: We're behind the city mountains; I can't believe this was here the whole time. The dragonfly throws them into a hole and they fall onto some leaves Reddie: Phew, we almost died twice today. Good thing there was this pile of leaves here to cushion our fall, otherwise we would have... Jan looks at the crystal clear water Reddie: Did you guys see? There were incredible creatures and monsters. I think we're in another dimension.
Jan: Guys, we're inside the temple.
Claire: Oh, you're right.
Reddie: There's something glowing back there, look! They arrive to see the 9 jewels—cyan, orange, light blue, blue, red, yellow, purple, white, and half-white half-black—floating Are these jewels?
Claire: It's a hidden treasure.
Reddie: Then let's take them.
Claire: Have you gone mad, Reddie? Don't you know from the movies that when you take a treasure, a deadly trap appears?
