Packing up the treasure materials and spiritual medicine, he used his divine sense to inspect the small tower, his expression suddenly froze, betraying a look of surprise!
This unassuming black tower was in fact pregnant with thirty-six layers of Earth Evil Restriction, and was indeed a top-grade spiritual artifact. It only lacked the unity of the Four Nines, and the formation of a Heavenly Gang Treasure Restriction to be promoted to a low-grade magical treasure.
Alas, this slight gap was as vast as the difference between heaven and earth; in the Cultivation World, perhaps one hundred top-grade spiritual artifacts might not produce a single magical treasure.
Zhao Sheng felt some joy, yet despite his vigorous pumping of spiritual power into the tower, aside from emitting a layer of black light, it did not display any other functions or effects.
It seemed this spiritual artifact, though extraordinary, most likely needed some special magic spell to be activated.
