Restoration vs Annihilation

As soon as the battle between millions of monsters, wood elemental creatures and undeads had reached the peak and the latter side gained an upper hand… a decisive move from the legendary rank tree-like creature suddenly turned the tide. 

The 100 meters wide massive green orb filled with life force and vitality it created exploded and a green wave of energy spread across the 10 kilometers radius where the battle was happening. 

It wasn't that the Six Guardians were strong enough to kill it or the legendary rank creature was unable to retaliate. It was actually in the process of creating this game-changer skill and didn't want any interference so it willingly retreated 10 kilometers backward contrary to Ceril's assumptions. 

And now, the corpses of the fodder monsters from the enemy side that were once torn and lifeless were restored to their previous state after the green energy spread over their bodies.
