The wars in the Heaven Realm were vastly different from those in the Lower Realm; in fact, there wasn't really a "battlefield" in the true sense. Everyone possessed Divine Powers to traverse the void. Even if they were billions of miles apart, they could arrive in an instant.
Wherever a battle took place, that was the "front line."
Thus, many tactics in the Lower Realm could not be applied.
However, this war was due to the Immortal Race advancing towards the Heavenly Palace, so there was a designated location for the so-called battlefield and front line.
Four Immortal Venerables had already been stationed in this place by the Immortal Race, with Master Merlin as the commander-in-chief. Two galaxy systems away from the Heavenly Palace, they built sturdy starry shelters.
