"I kind of feel the urge to call you dad or mom"

"...What do you think?"

"What can I think? Obviously, something is wrong."

The woman in white protective clothing knelt on the railroad tracks, taking samples carefully.

The red liquid flowing on the tracks was already half-dried, but a small amount remained. She carefully picked up the red fragments with tweezers and put them into a glass tube, and then she used a cotton swab to take some samples and put them into a container for preservation.

She placed the samples in a portable metal box and sighed, standing up.

The railway was completely blocked off, with many people in black combat suits fully armed and surrounding the area. It was heavily guarded.

"This doesn't look like blood. After oxidation, the color of the blood won't be so bright... I've been a forensic scientist for so many years. I at least have this level of discernment." said the woman in the protective suit.
