For instance, while the creature's ability at that time was indeed extraordinarily bizarre, its combat power didn't appear to be overly formidable.
It's easy to understand. If the creature's combat power were truly as strong as the ability it displayed, then Zhou Tian most likely wouldn't have survived up to this point.
After all, judging from every angle, the creature that absorbed Zhou Tian's blood was clearly not benevolent. When Zhou Tian hadn't noticed, it secretly sucked his Divine Blood. And when Zhou Tian did become aware of it, if the creature had the ability, it would've likely directly drained all of Zhou Tian's Divine Blood right then and there.
But the creature didn't act that way. From the moment Zhou Tian discovered it, the creature immediately chose to retreat. Observing its behavior at that moment, it wasn't difficult for Zhou Tian to gauge the actual standard of its strength.
