These Beast Soldiers were originally reluctant to come, as the distance between the edge barrier and the main water tank was too far. They didn't want to waste their time on the back and forth journey.
Eventually, it was Su Tang who proposed to reduce their water quota by five buckets — this made them happily race towards the edge barrier.
Just as all the Beast Soldiers ceased their actions, the barrier that was shrinking inward also stopped.
"The barrier isn't moving."
Upon hearing Gaiyin's voice, Su Tang turned her head.
Meanwhile, a flash of insight appeared in her mind.
On her recent journey, the lost insight was recovered by her.
That's it, thinking back to every previous barrier contraction, it seems someone was intentionally or unintentionally breaking white beads.
This idea surged within Su Tang, but she didn't speak hastily.
She was waiting, waiting for the next contraction of the barrier.
