Upon hearing Gu Shenghui's words, Pei Yan was even more confused and asked in surprise, "If it's not the Divine Artifact from the secret vault, then where did it come from?"
"It was left behind during the first ancient interdimensional invasion. At that time, the Plane Barrier was severely damaged, and all the Divine Artifacts brought to the cornerstone plane contained too much energy. If we forcibly brought them back to the original realm, it could easily trigger a chain reaction, causing the barrier to widen; hence, the various realms had no choice but to leave them in the cornerstone plane. As time passed, people from the major realms did try to send people to retrieve them but couldn't find them, so they had to give up."
