How thick is a python that is over a meter in diameter? Well, if a person stood next to it while it was lying down, its body would easily reach over their waistline. Such a size could not be embraced even by two people. You wouldn't need to have good vision to see it; as long as there's some light you could easily spot it.
When the python slithered towards the factory area where the lights were, rain dropped onto its dark scales, reflecting off into a myriad of light specks. Coupled with its colossal size, anyone who saw it would certainly have their knees buckle in fear.
Nobody noticed that the python was as sluggish as a worm, with a body so huge it moved slower than a snail — but who could pay attention to that when they were frozen in fear by its size?
