Empires & Puzzles Wanted Mission: Defeat 150 Holy Guardians

Wanted Mission is back, requesting you to slay 150 Holy guardians (yellow element.) 
To finish quickly, these are the two provinces with the most number of Holy guardians. Level 16 guardians are very easy for my strongest troop currently ( 2 five stars ascended one level, 2 four stars ascended 2 levels and 1 three stars fully ascended talent grid 4) about 3.8K strength. I could just leave them on auto-pilot mode. You could also place another Dark (purple element) hero to double the damage.
