Absolution for Bloodshed

By today's scientific understanding, the world is infinite in size.

That is to say, “Anything is possible.”

So imagine this scenario, purely hypothetically: intelligent species are a common and widespread presence in the world around us. A doctor says, drawing on what they have learned, “You really should know a little about your own body. Vampires have a hard time breaking down alcohol... Try not to drink more than half a liang a day, at least. That's the bare minimum for your health.”

This has become common knowledge among more than half the population. And now, this half-open door is about to swing open for you.
