Draco's eyes flashed with anger at this open defiance, but he quickly calmed himself down. He suddenly understood that with his current power and understanding of his bloodline, he would never be able to make these three kneel.
Fortunately, that wasn't his objective... at least not this time? His goal here was to make the lesser aspects of his three main bloodlines acknowledge his presence and control, which had already been achieved.
Hence, the 100% success rate.
Now, Draco understood why the AI had analyzed his class and generated a Rank up Scenario for him at 100%. It had extrapolated further paths for development, but broke them down into stages that Draco could achieve at a certain point in time.
Indeed, if the goal had been to subjugate them all, his success chance would have plummeted from 100% to barely 1%. To get those three fellows to kneel and call him ancestor? Practically impossible!
