Chapter 4.25
When I turned behind and looked— I was genuinely surprised by the sight of it.
A visible crack— spreading left and right across Kuroyuki's ice wall could be seen.
Behind it, was flooded with countless silhouettes. They were sticking onto her ice wall. It seems they were trying to break the wall by pushing it with their mass instead of breaking it.
For some reason, Kuroyuki seems to be in pain when she tried to restore the crack with her power. It seems she's almost at her limit to maintain that wall.
But if she opens up a small hole now to let them pass through, that will be the breaking point of the entire wall, and it would still collapse.
Kronos is at the 4th pillar on the left, right next to us.
"I got this," Rumelia said to us.
Which, thin threads of silver strings sprout up from the floor— sticking to the wall and ceiling edges like a spider web with a random pattern.
