The skill All For One was undoubtedly a skill worthy of the word UNIQUE. Although Bai Zemin did not know exactly what the most noticeable differences between "normal" skills and "UNIQUE" skills were, the two UNIQUE skills that Bai Zemin had received so far were undoubtedly tremendously powerful.
For example, the skill Blood Berserker's Wrath that Bai Zemin managed to unlock during the war against the goblin race when the leader of the goblin race located in northern China was a skill that in Bai Zemin's eyes could simply be described as a godly skill. After all, depending on the level of wrath awakened, even a normal human could receive more than enough power to fight against a Third Order existence that had spent tens of years and even centuries to acquire such power or even more!
That was how powerful the UNIQUE skills were and the newly acquired All For One was definitely not far behind despite the clear difference it had with Blood Berserker's Wrath.
