Bab 1579: "Summoning Gate of Hell" 

Lucifer was not an idiot either, and the moment he saw Michael summoning the Gate of Heaven, he knew that this commander of the army of God wanted to bring his people along to fight him. 

Hmph. He is also the king of all demons and he also has his own soldiers! 

Lucifer hurriedly cooperated with Atherton to open the Gate of Hell. 

Unlike the Gate of Heaven and the Gate of the Underworld that was summoned and appeared  in the sky, the Gate of Hell appeared beneath the seabed, deep inside the sea. 

It would be said that it was opened at the center, the world's core, where the temperature was the hottest. 

The Gate of Hell was opened with the sound of the devil's trumpet spreading throughout the two domains from the depth of the land, deep under the earth. 

If the angel's choir and the trumpet of war sounded from a distant sky somewhere, then, the devil's trumpet sounded from the depth of the world itself.
