It is thanks to these changes that the Human Race has gradually gained an advantage in continental competition.
From the standpoint of the species, these reforms are undoubtedly of great strategic significance.
However, for the lower class citizens, it may not be a good thing. At least for this generation of the lower class, it's somewhat cruel.
Not only do they have to fight against Different Races, but after defeating them, an internal war within the Human Race might erupt.
There's no reason to feel guilty; victory for the species is the key to the future, and the fate of a defeated species is naturally fertilizer.
Moreover, the downward permeation of military affairs is also an opportunity for the lower class to change their social status.
One shouldn't fear intense competition among nations, but rather fear them becoming complacent without a competitive spirit.
