Your line looks as an object coordenates: X, Y, Z, RotX, RotY, RotZ. But it's strange, should be 0.0, not 0.
If they're, you just need X, Y, Z, and use them to set player position.

If you want go underground you need less value in Z, for example, we have 5.5 which is the ground, to go underground you need for example 5.0 or less, something as 4.5
Good luck!
