A white threadlike line stretched from the spherical body of the Ling Wan, extending from the top of its head to between its buttocks. At this moment, Yun Xiao's other hand also touched the endpoint of this white line, his Meridian Qi drilling into it, seemingly enacting some unknown technique.
Whoosh!
As Yun Xiao's hand infused Meridian Qi into Ling Wan's body in a mystical manner, a black threadlike line emerged on the corpulent body's back, starting from between its buttocks and spanning upwards, halting where Yun Xiao's right hand touched.
The two lines, one black and one white, appeared to bisect the ball-like body of Ling Wan, yet the colors remained starkly distinct, with neither line interfering with the other or sharing any visible linkage.
