Su Yuan darted out from behind the boulder and approached the two demons. With swift precision, he extracted the demon cores from their bodies and stored them in his spatial ring.

The Abyssal Key has the function of detecting Abyssal Crystal veins, which is exactly what Su Yuan needs right now. As for the bodies of the two demons, they are of no use for the time being... No, wait. Once the Primal Demon Egg hatches, it seems it can devour demons to grow stronger. Better keep them for now.

Zhang Zhengqing, who had come to Su Yuan's side, was momentarily stunned when he saw the two demon corpses vanish into thin air. The Black Emperor sneered, "It's just a storage ring, kid. You really haven't seen much."

As for Su Yuan, he was pondering how to explain this to Zhang Zhengqing.
