Just as Xu Fan was thinking about future plans, dozens of light curtains appeared beside him.
Outside the Steel Great Wall, a vast army of Demons was gathered.
This time, figures from the Four Great Demon Clans appeared among the army of demonic beasts.
The illusory shadows of the Four Demon Sovereigns hovered in the sky, and an astonishing killing intent filled the air.
"Oh ho, they haven't learned their lesson yet. The Demons are still gathering en masse." Xu Fan said, looking at the large congregation of demons in the light curtain.
"Grapes, let the four Demon Sovereigns each have a shot at the main gun."
"The auxiliary gun will strike in a covering style." Xu Fan waved his hand and said.
If their teleportation array hadn't been sealed, cutting off the supply of materials for making main gun shells, Xu Fan would have dared to bomb the Four Great Demon Sovereigns with the main gun.
"Yes, sir."
