Star Letter Gu

In Imperial Court blessed land, Hei Lou Lan’s attendant Hei Shu hands him a star letter Gu that Wolf King Chang Shan Yin sent back, and Hei Lou Lan reads it by sending his mind into the Gu. Fang Yuan, acting as that Wolf King, later receives another star letter Gu that tears through the sky, carrying Hei Lou Lan’s demand that he return. ^{ch. 556}

As it flies it shines in the air, creates a huge commotion, and is easy to intercept, though Imperial Court blessed land removes that worry. ^{ch. 556}
