It should be because your bathroom is damp and then not cleaned often, so this moldy mold will grow on the wall or anywhere, and it will continue to spread, and you need to wipe it clean.
Unless you know the location of the sewer pipe, you can't punch the hole.
Make a hole in the ground and change it all to the shed below.
Don't worry, there will be no water leakage, the kitchen and bathroom floor slabs are generally made of cast-in-place reinforced concrete, which itself has a waterproof function. If the water leaks when a groove is made, the upper and lower water risers have to penetrate the floor slab, what will it leak into? The key is to take care of the waterproofing around the riser, which is generally leaking from here.
Find a plumber to repair it, re-do the waterproofing and replace it with a new one.
