Hao Ren could never understand why a goddess like Raven 12345 was so unreliable…
That aside, the pair of metal rings were quite useful.
According to Raven 12345, they were used to generate remote mass projections, and Hao Ren had actually seen such a thing before. Based on his understanding, the mass projection was a type of remote interactive interface that had an entity, which could transmit senses and interact with the environment. Its essence was a kind of image transmission, but the advanced technology of the Xi Ling Celestials in the field of information operation greatly expanded the "content" of the transmission, making it feel like the real thing. But at the same time, it reduced the interference of information by countless times, and that was one of the key conditions that allowed Rheia to "enter" the Surface World through the Wall of Reality.
