In order to fight against the Ancient Ming and its forces the Dark Crow was forced to create powerful Legions of Human Race's cultivators in order to fight them and to later carry out his will throughout the Nine Worlds during the Emperors Era and they were:
- Brave Tiger Legion: The fiercest Legion. It is currently sealed inside Dark Crow's Palace in the Bi'an Beastworld.
- Azure Dragon Legion: The bravest/most destructive, Legion. The Veterans of the Azure Dragon Legion became the Old Ancestors of the Heavenguard Sect and trained the elders and disciples of the sect.
- Silver Fox Legion: The craftiest/wiliest Legion.
- White Crane Legion: The most secretive and mystical Legion.
Besides these four, there are three other known Legions:
- Godslaying Night Corps: It was Dark Crow's first Legion created for fighting the Ancient Ming. Both the Godslaying Night Corps and the Azure Dragon Legion took part in the Immortal Execution War.[?]
- Black Dragon Legion (黑龙王军团): It was the army created by Black Dragon King that dettered the three last generations of the Emperors Era.
- Vermilion Bird Legion (朱雀军团): It has many illustrious battle records.
- Other Imperial Legions
