Eliminating Zhou Tian would only remove a potential threat for them, but if they could conquer Zhou Tian, their gains would be substantial.
Although they were unaware of Zhou Tian's identity, those forces understood that if Zhou Tian were to "create" an Abyssal Power System, given enough time, becoming a high-level figure within the Divine Race would be inevitable. If they could draw Zhou Tian into their camp at present, it would be beneficial not only in the future but also immediately.
Thus, faced with the tremendous benefits of conquering Zhou Tian, those forces, despite having great inherent dislike towards him, ultimately had to restrain the impulse to directly attack Zhou Tian due to his value.
As a result, given the situation at the time, since those forces had the idea of utilizing Zhou Tian, they opted not to attack him immediately but instead chose to send people to interact with him, hoping to compel Zhou Tian to join their camp based on the strength they displayed.
