Yes, currently his strength is increasing at too slow a pace, but if he can absorb Affiliated Civilizations and transform other powerful Trial Civilizations into part of the Human Civilization System, his cultivation speed will definitely see a substantial rise.
Yes, the newly joined Affiliated Civilizations are not deeply connected with Shen Hao due to loyalty issues.
But it also depends on the level of the Affiliated Civilizations.
Any civilization in this Trial has strength not less than, or even exceeding, the Human Civilization System's apparent power.
Under such magnitude and level, although they cannot easily be absorbed as Affiliated Civilizations like before, once absorbed, the effect obtained far surpasses the past.
After confirming that this is the only way to break the impasse, Shen Hao did not target those relatively weak Trial Civilizations.
Instead, he chose the Oak Civilization!
Yes, he chose the most powerful Trial Civilization!
