Ancestral hall.
The ancestral hall on top of Wu Yi Mountain was a mortal Gu House. Using a large number of rank five mortal Gu, even though it was inferior to Immortal Gu Houses, it was extremely significant to Wu clan.
Essentially, every super force and normal force would have an ancestral hall. Inside, life tablet Gu and soul lantern Gu would be used, or even blood rope Gu.
The former two were common, while blood rope Gu was rare, because it was blood path.
Even the small and big sects in Central Continent had buildings similar to the ancestral hall, storing life tablet Gu and soul lantern Gu.
At this moment, Wu Ba Chong was standing in the ancestral hall, looking at the Gu worm fragments blankly.
After the life tablet Gu shattered, it would be like wood scraps, while soul lantern Gu would become a cracked ladybird, it would not be shining with a dark blue light anymore.
