Following the Netherworld's invasion, the higher-ups of Wolf Fang City issued a notice stating the everyone had to report to the three armies within three days of receiving the notice. There, they would receive commands from the generals and fight together against the Netherworld.
This time, it didn't matter whether one had retired from the army or not, nor did it matter how many merit points they had accumulated. All Immortal Realm elites still present in the Two Realm Battlefield were obligated to participate in the battle against the Netherworld. Moreover, an urgent call for reinforcements had already been issued, and it wouldn't be long before more elites arrived at the Two Realm Battlefield.
The Netherworld had suddenly elevated the small skirmishes into a full-blown war, and it was crucial that all the elites on Cloud Apex Planet were mobilized to participate in the resistance.
