Above the Giant Sword, the radiance on the Sword Talisman was bright. Ahead in the void, Lin Chen stood on nothing, with the Myriad Formation Board floating in front of him like a slowly unfurling scroll. It opened gradually in front of Lin Chen, leaving behind a curtain of white light.
Lin Chen extended his index finger, touching it to the white curtain of light. Spiritual power surged from his fingertip into the curtain, instantly leaving a bright trace.
Lin Chen was quite surprised. "Isn't this just like drawing on a touchscreen?"
Interesting!
The Formation Disc's Curtain of Light was like the screen of a touchscreen device, and Lin Chen's finger acted as the stylus, free to sketch at will. If there was an error in the Array Formation being sketched, the spiritual power would become chaotic, resulting in the entire curtain shattering.
