After talking with Sun Yu, Wei Yuan was inspired and came up with a new plan. He asked Ji Liuli to design a "Gathering Qi and Nourishing Yin" formation, then set it up in several vibrant locations within the Boundary Domain. Immediately, Wei Yuan ordered the excavation of countless shallow pits within these formations, each seven feet long, two feet wide, and two feet deep.
These pits were neatly arranged, looking from a distance like a densely packed graveyard, which they indeed were. The formations set up were also meant to improve the feng shui of a graveyard. However, since these graves were located in areas of high vitality and continually gathered qi to nourish the yin soul, over time, they were likely to cause corpse mutation.
