Lei Wenjun didn't expect it.
He had just descended to the 28-meter area when he discovered such an astounding situation.
A footprint more than three times the length of an average human's—what kind of concept is this?
It's little known.
By measuring the size of a person's footprint, it is often possible to infer their normal height.
This technique is used quite a bit in criminal investigations, and authorities even have different calculation templates based on different shoe types.
In everyday life, we don't need to calculate too accurately; a more standard formula is that an adult's height equals foot length at age 13 times 7, plus or minus 3 cm.

The foot length of an average adult male is generally between 22 to 26 centimeters, with an adult height ranging from 160 to 185 cm.
Let's take three times the foot length to be 70 cm for calculations.
