Chapter 77: Invisible Light

The special ability of the Green Pupil Magic Serpent, could it really filter out invisible light in its field of vision?

Like infrared light, for example?

Well.. wait.. it shouldn't be referred to as infrared, this is a term in the scientific field.

Xia Zhou responded, actually, infrared light has a usage that has been used for a long time within the alchemy school.

It refers to the bluish light that can see through the bodies of living creatures.

The alchemy school calls this light beam the "Biological Penetrating Beams", and in the Tower Scholars school, the spell to cast this light beam is called "Biological Penetrating Ghost Light".

In Xia Zhou's view, Biological Penetrating Beams are essentially the application case of infrared light in the alchemy field, paralleling the Vein Imaging Device in the scientific field - if a nurse can't find a vein for injection, she would use the infrared light of the Vein Imaging Device to detect the veins beneath the skin.
