It appears that the strength Zhou Tian demonstrated wasn't very strong, yet the true power of Zhou Tian's ability is something that cannot be overlooked by those high-level Fallen Elves.
Even if the Abyssal creatures summoned by Zhou Tian aren't as strong as those Fallen Elves, if their numbers increase slightly, those Fallen Elves back then still felt threatened. In other words, at that time, the Abyssal creatures summoned by Zhou Tian indeed had the ability to threaten the high levels of the Fallen Elves.
Moreover, the strength of those Fallen Elves back then was not weak; even though they couldn't compare to the Gods of the Burrow Spiders, they could definitely be considered top-tier powerhouses in the current world. It is believed that if the number of beings at their level increases, they might even have hope of defeating the originally invincible Gods of the Burrow Spiders.
