The exterior of the Immortal Official Medicine Repository was rather strange. It looked like a gigantic building modeled after a pill furnace, and the position of the main gate was the fire-feeding mouth of the furnace.
In terms of structure, this kind of bizarre building had distinctive features, but it was not regular enough. Theoretically, it was unsuitable to exist alone as a Palace City building.
Unless it possessed some special function.
As far as Wang Yu knew, among Heavenly Formations, there was a peerless marvelous formation called the—[Ninety-Nine Earth Furnace Immortal Nurturing Formation]!
The Earth Mother Scripture recorded that this formation was said to be able to help a person ascend to immortality in broad daylight.
Simplifying it, changing it from ninety-nine earth furnaces into a single Water Nourishing Furnace used to nurture spiritual herbs and precious pills, was naturally also a first-class Mysterious Feng Shui Bureau.
When arranged by human power, it was a Human Formation. A Human Formation was not necessarily inferior to an Earth Formation; it was merely very difficult for it to be comparable to a Heavenly Formation.
Nature was a cultivator's best teacher, and learning from nature also contained this hidden layer of meaning. Many Feng Shui Secret Arts and methods of arranging mysterious formations had almost all been learned from heaven and earth.
At present, this yellow-brown building that closely resembled a pill furnace not only had exceptionally good effects, it also possessed very strong defensive power.
Wang Yu spoke up from the side to give instructions.
"We Feng Shui Geomancers never take the main gate. That's the path left for fools. Go to the Li Position. This place overcomes fire, so the protection at the Li Position is the weakest. Slowly erode it with your yin lightning divine ability."
"—All right!"
