Sniffing warm blood

Mac was lying flat out on his belly in the cold snow, scanning the evening landscape through his sub-spectral goggles.
The Lhasa entourage had given in to the weather, and was probably sleeping already inside the snow cave. Something radiated heat from within the snow.
Human heat, he guessed.
Fuelled by warm blood.
"Success.", he whispered to himself.
Luckily, the howling storm didn't interfere with the vision through the goggles, even if all he could see with his bare eyesight was white stripes of hurling snow. Another point added on the list to shut the mouths of the technology skeptics that seemed to fill the planet - like the ones he was hunting down on this very assignment.
For all he tried - not that hard, when he came to think of it - he couldn’t understand the resistance the House of Lhasa and all the Traditionalists had put up against all this wonderful new technology. They feared it like the plague, mostly based on their silly old tall-tales of global catastrophes in ancient times and other far-fetched myths.
It was a case of standing in the way of progress.
His progress, among others.
They simply wouldn't accept that the whole area of the Middle-North was all turning pro-tech these days, and that the new prosperity they were encountering was mostly due to the fact that people in his region were open to new thoughts. Embracing technological progress was a big part of the new thought that was about to lead them into a bright new future.
Of course, they had to get themselves into trouble like this.
Fatal trouble.
He remembered the day when he left Riga for the Northern Ice. On his way down towards the zeppelin pier he had noticed something he hadn’t seen before. Some brand new, electrically illuminated boxes had been put up next to the walkway. They were all the same size, about three by two foot, and across a shiny synthetic surface were printed a set of historical 'reminders'.
These had always been around, though always made out of natural fabrics and materials, hopelessly illuminated by smelly candles.
The new ones shone with bright electrical light.
Much more sensible, although the puzzling thing about this was that he’d never seen progressive technology applied to Traditionalist nonsense like this before. It made him wonder who put them up; Traditionalists loosening up to progress or forward-thinking people caught up in old bullshit ways of thinking.
One of them had read:

I

feel

You

feel

He feels

She feels

It feels

We

feel

You

feel

They

feel

All religious nonsense and nothing the world needed in this day and age.
Maybe these people would become less backwards-thinking now that he was about to sneak up on them in the night, and that it was all down to his utilization of recently developed tools that enabled him to track them down?
Pity they wouldn't live to be able to change their ways.
