Even if a certain hedgehog constantly experiences misfortune from dawn till dusk, it doesn't mean that unlucky events are happening at every single moment, right? If, say, a staggering hundred misfortunes occur in one day, that alone would suffice to deem the person an embodiment of misfortune. Still, after setting aside those mishaps, it's indeed the case that most of their day operates under normal circumstances.
And currently, relying on the Qilin's Domain Power, it has probably just squeezed Zhou Tian's luck down to Kamijou's level, at most perhaps causing a bit more misfortune than Kamijou experiences.
But no matter how much the Qilin's Domain affects him, Zhou Tian, whether in offense or defense, is able to maintain his standard level for the most part. Although it's fair to say that, even sustaining his usual level, Zhou Tian still found it relatively challenging to deal with its attacks.
