In the past, one had to choose a suitable mountain spot with great feng shui if they wanted to create a typical formation. Formations were extraordinary, and they exhibited mysterious effects.
Then came the era of recuperation of reiki, where formations could be drawn anywhere, be it on a piece of paper or a piece of wood, basically anything could be used as a material to draw a formation. As long as the formation was perfectly drawn out, and with the help of a Spiritual Stone to trigger the reiki from the heavens and earth, the formation would finally be complete.
Although it was currently the era with weak reiki, the Human Body Tactical Formation itself was unique all along. It could be formed even on a flat ground, and coincidentally, the place where Sakagami Village was holding the ritual was indeed a spacious flat land.
