Zin couldn't refute William's words. All he could do was to think again about what William said. A formation that was able to rewind time, make a copy of a certain point of it, and bring forth another scary wave of monsters… That was indeed the scariest thing he could think about, especially now.

Even if they came here with fresh and grand forces, he was sure it was impossible to repeat the same feat again.
