A massive amount of black soil surged forth before Fang Qingyuan's palm. It poured out from his Immortal Mansion—soil that the mansion had not yet had time to absorb. Over the past six months of continuous collection, some of the black soil had always been left over, piling up little by little until it formed a mountain, saved for later use.
The transparent barrier before Fang Qingyuan was a one-way shield—things could exit, but not enter. This was merely an observation room; if anything else were allowed in, it would likely be instantly buried by the black soil.
The expanse of black soil stretched for tens of miles. At its very bottom lay an unknown abyss, like a deep-sea maelstrom, that possessed a powerful suction. If one were to fall into the black soil, the pull they experienced would be proportional to the amount of Spiritual Qi in their body—the more Spiritual Qi, the stronger the suction.
