Five Monarchs' Ambush

Consort Tian Si and Mo Yin both had different styles; with the Almanac of Fate and his overwhelming intelligence, Mo Yin excelled in planning, formation organizing and the altering of fate. He was a master strategist. He led his army in two different styles, one straight forward and the other conniving, making him a formidable foe.

Consort Tian Si, on the other hand, was different.

She possessed the Almanac of Karma, manipulating karma, creating chaos throughout the process. Unlike Mo Yin, she was not a good commander, but she was unrivaled in setting up plans and schemes, each connected to one another, leaving no gaps untouched.
