No matter what kind of resources the Dragon Horse Galaxy is willing to offer to humans, it is a good thing. Regarding the issue of the Deep Red Realm, the two major federations must unite against a common foe.
The opportunity to return to the Douluo Federation this time was unexpected, or rather, a pleasant surprise for him. Taking advantage of this opportunity to return also allows him better communication with the federation over there, to determine the next course of action.
This time, the reinforcements that arrived are from the Seventh Fleet, but according to the information he had previously received, it was supposed to be three cosmic fleets. However, only one came. In such a situation at the time, if the Douluo Federation had sent all three cosmic fleets, it might have severely damaged the Deep Red Realm.
Of course, it's also through this experience that he realized the true strength of the federal fleet of the Douluo Federation.
