There are tan and gray pieces

Question

And the two flame pieces, with smaller bag inside.

Answer 1

I started looking at sets containing a 6L technic axle in red, and I soon came across 60216-1 Downtown Fire Brigade :

Your bag looks like it contains the main building there - 1x6x5 tan panels, 1x4 bricks with brick pattern, 1x6x1 grey arches, they're all in there.
