With the four blue suns rising, terrifying blue rays swept passed the entire place. These blue rays with a destructive searing chi didn't allow a single demonic immortal spirit beast to live. Large areas of demonic immortal spirit beast fell while this blue sun expanded slowly from tens of km to hundreds of km.
Ye Mo could expand it bigger but he stopped, the larger it was the more consuming it was. He charged amidst the demonic immortal spirit beast and they were blown down like the wind.
It was much easier to move around than expanding the Heaven Flame Nine Suns.
…
"Help has arrived."
Everyone on the city walls saw what was happening outside, then they were dazed. Four blue suns moved around the city, demonic immortal spirit beast that stretched beyond the edge of spirit sense fell down in large areas.
This was like a howling wind blowing past not leaving any behind. What reinforcement was this? it was too powerful, too scary.
