Gu Qiulong's face underwent a series of changes between gloom and brightness as he once again pulled out a handful of spirit stones from his storage bag to replace the spent ones.

This scene had unfolded several times already, and Gu Qiulong had nearly spent over two thousand spirit stones. His usually calm and composed face now bore furrowed brows and was drenched in sweat.

On his ninth replacement of the array's spirit stones, nearly depleting his storage bag, an unexpected change occurred. Accompanied by a thunderous boom from above, dazzling lightning bolts suddenly erupted from the purple wooden column, cascading down swiftly as if drawing in the natural lightning from outside, causing the entire dungeon space to shake violently.

The purple array on the stone platform also brightened abruptly, its operation speeding up manifold. Streams of white spiritual power surged out from the spirit stones, infusing into the Winged Bird Egg.
