After the cataclysm occurred, Chaos became much more active than in the past. Among them, there were certain special enemies marked as arch-enemies by the Death Angels. They never publicly acknowledged it, but Gu Hang already knew of their existence, and they appeared more frequently.
Internally among the Death Angels, they are referred to as 'Fallen Angels,' reportedly traitors among the Death Angels.
Gu Hang knew about this very early on due to the rebellion incident involving the Oath of Remembrance Battle Group, he even communicated with the Death Angels about it.
The pursuit of Fallen Angels is a top priority for the Death Angels, with a significant portion of their efforts focused in this area.
Expanding occupied territories?
For the Death Angels, it is far less important than hunting down the Fallen Angels.
Honestly, Gu Hang was dissatisfied with this. But in the past, he had no justification or ability to command the Death Angels to do anything.
