step 1: Prepare some small inflammable (tissue, matsutake, Hay, etc.)

step 2: use the blade to scrape some magnesium shavings and integrate the scraped magnesium shavings into a small pile of flammable materials (paper leaves sprigs bark, etc.)

step 3: only by scraping quickly with a blade can Mars be effectively scraped and magnesium shavings be ignited, thus generating flame.

Usage skills

1. choose fire Velvet (it is obviously not wise to directly ignite branches with Sparks);
2. when starting a fire, keep Firestone as close as possible to the fire pile, reducing the time Mars stays in the air before falling on the fire pile (directly on the fire pile is the best).
