Capítulo 419: Preparation For Demon Invasion.

It is strange that demons are attacking the Zargoth plane. Demons used to attack the plane but they've always been beaten back by the combined efforts of the gods. The order that the Celestial Supreme enforces ensured that demons stood no chance against them. So they became discouraged about attacking the Zargoth plane and left it in peace for numerous Origin cycles. So this attack seems odd.

'It shouldn't be a problem. Probably just an ignorant small-time high-rank demon who doesn't know what's good for him. The gods will beat him back immediately.' He thought to himself confidently.

The divine plane determined that the threat level is just 1A. It means that the attack is coming from a single abyss altar belonging to the fortress of a high-rank demon. The divine plane determined this because it couldn't sense the mark of sin of a demon noble or anything above that and the portal was opened by a high-rank demon.
