Chapter 1612: "Silencing The Guardian Angels"

However, since the gate was there even before the domain was strengthened to the current domain... 

There was a huge chance that a domain core would appear around the gate. 

There was also the lava sea and the blood moon in the sky. 

These two places were also suspicious, but because a blood moon was impossible to reach, the Holy Spirits were more interested in the Blood Castle at the center of the Blood Kingdom on the huge island. 

Hell Break Domain made the single castle not lonely anymore, and there was also a strange city surrounding the Blood Castle and people called it the Blood Clan kingdom.

It wasn't suitable to call it a kingdom when it only looked like a small town, but it might be the capital of the 'kingdom', the reign of darkness that turned into Hell Break.
