"How do you think Secret Art Crystals are carved?" Vivian did not directly answer his question about the Forest Spirit, instead suddenly asking something else.
"Crystals..."
Mu You paused. In theory, Secret Art Crystals were harmless magic circuits constructed by unraveling the principles of Black Magic and using its most primitive, fundamental logic.
That sounded simple, but stripping away the core of Black Magic and extracting its purest elements was no easy process.
"Pure Black Magic Circuits inevitably have to be worked out by someone, stroke by stroke. But Black Magic isn't like ordinary magic, which can be studied freely. Every attempt is a dance on a knife's edge, carrying the risk of losing control upon failure."
"Under those circumstances, Forest Spirits, which possess the power to absorb Black Magic Power pollution, freely change their forms, and perfectly simulate the operation of the human body's magic circuits, are the ideal test subjects."
"..." Mu You fell silent. With Vivian bringing this up now, he had already begun to vaguely understand.
"Forest Spirits are a peaceful race. They're gentle by nature and dislike fighting. Their daily work consists of absorbing all kinds of pollution for the earth. Every Forest Spirit's core can contain enormous amounts of pollution, and they also possess the ability to break it down. Ordinary pollution can be broken down the moment they absorb it. Only a very few kinds of pollution that are difficult to break down accumulate inside them, such as pollution from Black Magic Power."
Vivian looked at the rampaging Forest Spirit in the distance. "And this Forest Spirit is the most severely polluted by Black Magic Power among its people. Its innate ability to 'detoxify' is very poor, causing it to accumulate far more Black Magic Power pollution than the others. At this rate,
