"Unexpected Underwater Transportation"
Even if the glass bead seed looked extremely sturdy and reliable, there might be special situations where they were fished out of the barrier and were exposed to real danger outside.
The mermaid also felt the malicious gazes hiding in the dark, and she immediately knew that those gazes should belong to the slum monsters deep in the slum.
"Everyone, be careful. We might encounter a lot of desperate monsters and our priority is to maintain the barrier!"
"Everyone also has to make sure that no one will be ejected out of the barrier through some strange means, get it?"
The mermaid could feel her heart beating hard in her chest and even her face became a little bit paler than before.
If anyone was suddenly thrown out of the barrier, that person would die without bones within seconds.
