In the underground holding room of the Night Watchmen headquarters in the capital.
Elder Zhang and the two Battle-Kings were dealing with the other mutated creatures, while Elder Perkin and the other three Battle-Kings had recovered a little and joined in.
Not far away, there was a deep darkness quietly covering that area. From time to time, there would be a rumble, and a terrifying aura would seep out at any time.
Elder Zhang and the others would look at the Darkness Domain from time to time, worried about Li Xinghai.
If Li Xinghai hadn't used the Umbral Realm to place the battle area in the domain, the entire underground storage room would have been destroyed. Even the headquarters of the night watchers would probably have ceased to exist.
This was a terrifying battle between Battle Emperors!
"I wonder how the situation inside is now."
A worried expression appeared on Elder Zhang's face.
The others were the same.
