David saw it—and was genuinely surprised. That method had never crossed his mind.
But he knew enough to understand one thing: poison energy was very different from external poison.
Technically, external poison was safer. But bringing something like that into the Virellano residence was far too risky. The family didn't tolerate that kind of thing within their grounds.
Which left only one option for poisoning—poison energy.
A type of energy born from the negative side of nature energy.
Just like nature energy, which existed everywhere, this energy was also present—scattered, subtle, but always there.
The difference was… using it was far more complicated.
And one of its biggest drawbacks—contamination.
Unlike external poison, which could be easily cleaned off—sometimes even just washing your hands was enough—poison energy tended to mix with the user's own energy. Its residue lingered.
Long enough to be detected.
