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. Even if he lost, he would still be able to retreat with his men safely.
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.
