Du You was still researching the Northern Empire's affairs, since it was the first native world empire, and held much research value. Moreover, several northern alliances also showed signs of forming an empire.
Unfortunately, establishing an empire model is no easy task.
For instance, the reason the empire could establish itself was because a powerful late-tier eight strong figure led it; without such a figure, it's hard for others to be truly convinced. As for those at tier eight's peak, they have mostly entered the core regions.
Even those late-tier eight individuals remaining here find it hard to rise, and that guy's thoughts remain uncertain.
In the end, a late-tier eight nearing peak strength, who is also an alchemist capable of producing large numbers of puppets, constitutes an essential factor of the Northern Empire. The other alliances have no way truly to merge together.
