Sure, here's the translation:
Meanwhile,
at the deepest part of the Demon Realm, several pitch-black Demon Gates stood anciently.
Suddenly, one of the Demon Gates rippled with a strange wave, causing the entire space to tremble.
Almost simultaneously, all Monarch Level Demon Monarchs appeared, half-kneeling on the ground, their voices filled with restrained fervor,
"Welcome, Lord Demon God!"
The wavering of the Demon Gate paused for a moment, then a deep voice, as if from the depths of the netherworld, slowly emerged:
"The Divine Secret Realm of the Human Race has opened."
"Proceed as planned."
"The Divine Pattern... must be obtained!"
As this command was issued, the demonic Qi surged like a tide.
All the Demon Monarchs bowed their heads, responding in unison,
"We obey the Divine Mandate!"
As this command was transmitted through layers, the entire Demon Realm seemed like a fierce beast awakening.
