"This has been a long battle. In this battle, we couldn't trust most people. Due to immature technology, we couldn't detect every Banished Immortal, so we could only abide by the principle of better to kill wrongly than to let go. Even so, we couldn't be sure how many Banished Immortals still existed within the Immortal Alliance. And even if they weren't Banished Immortals, they couldn't necessarily be trusted. The power possessed by Immortals was simply too great; anyone could be tempted. Despite this, we were fighting for the mortals," Feng Luoyi said, looking straight at Wang Qi. "Only those Cultivators above the Primordial Spirit could be certain that their interests were fundamentally aligned with the Immortal Alliance. Only those who became Carefree Cultivators could be deemed trustworthy. However, even the Carefree could potentially lose their heart and abandon the Modern System."
Therefore, the means obtained from Zhao Qingfeng seemed crucial.
