Silly Chu strenuously stuffed the pillow into Xin Lin's hands, quite obstinately.
Xin Lin was puzzled, and upon looking down again, the pillow was still a pillow; could it possibly hatch chickens?
Upon closer examination, she noticed that the dried grass core inside the pillow was somewhat peculiar, dotted with tiny black spots that would be hard to detect unless scrutinized.
Xin Lin gasped, the air imbued with Fu Xi's Energy, as she closely observed those grass cores.
Under the influence of Fu Xi's Energy, the slender grass cores, barely the thickness of a needle, enlarged in Xin Lin's eyes, and the black spots gradually became discernible.
The dots expanded from small to large, turning out to be not mere grass patterns, but characters.
Xin Lin's pupils slightly contracted.
Mystical Medicine Book!
Hidden within this decrepit pillow was the Mystical Medicine Book personally authored by Chu Beiqing.
