There was a complicated array drawn on that page. It was roughly in the shape of a pentagram, and each corner of the star was drawn with a relatively abstract pattern.
"What's this?"
Li Xuan saw Bai Lin squat down and put the booklet to the side then pick up a branch and begin to draw on the ground.
Very quickly, a formation that was exactly the same as the one in the booklet was drawn.
"Xiao Lin?" Li Xuan was shocked. "You know how to do this too?"
Bai Lin patted the dust off her hands. "It's just a basic drawing. Look, each of the five corners of the pentagram represents one element, which are metal, wood, water, fire, and earth. They're all quite easy to find."
She tapped the tree branch at each corner and finally gathered at the center of the formation. "But the most important thing is the one in the middle. If there's no food for the cat, the formation won't work."
