"Oh no, the energy defending the Treasure Refining Hall is nearly depleted!"
The Vice President of the Meridian Refining Master Guild, Qian Sanyuan, had once partially managed the Refining Treasure Hall, so he understood it more than others, and at this moment, he spoke with a grim expression.
Although the Refining Treasure Hall is a space divine artifact, its energy does have a limit. It must accumulate over many years to achieve an extremely high defensive power.
Of course, if some high-rank heavenly materials and earthly treasures are continuously thrown into the Artifact Heart of the Refining Treasure Hall, perhaps its energy could accumulate slightly faster.
However, at this moment, the master of the Refining Treasure Hall, Yun Xiao, was in a special state, naturally unable to control the Artifact Heart, so the Refining Treasure Hall could only passively endure the attacks of the Holy Grade Heavenly Spirit.
