Dream Pillow Gu

Feng Jin Huang runs to Duke Long holding a newly refined rank five dream pillow Gu and asks him to look at it. Duke Long glances at it and calls the result not bad. She answers that she failed many times before succeeding once, and that with this Gu mortal Gu Masters can enter dream realms if they sleep while laying their heads on it, which she expects to help Spirit Affinity House and Central Continent. ^{ch. 1619}

Effect and reach

Cited text treats dream pillow Gu as ordinary to look at, yet useful because it is a mortal Gu most Gu Masters can use. Mass production would let Central Continent Gu Masters enter their own dream realms and extract dream path Gu materials, which Feng Jin Huang frames as an early advantage in the great era. ^{ch. 1619}
