Not to mention being able to escape Zhou Tian's entanglement, but even with the abilities Pan Shi possessed, if he wanted to elude Zhou Tian for a moment, that wouldn't be a problem either. Given the situation at the time, if Pan Shi could have gotten some time to heal his wounds briefly, Zhou Tian's efforts would naturally have been in vain.
Zhou Tian was well aware of the situation, which is why he seemed to completely lack confidence in Killing Pan Shi. However, lacking confidence was one thing, but having reached this point, even without confidence, as long as there was an opportunity, Zhou Tian would still strive to try and kill his opponent.
Thus, Zhou Tian kept desperately attacking Pan Shi, but he couldn't kill him nor restrain his actions. Therefore, just when it seemed Zhou Tian was about to kill Pan Shi, Pan Shi successfully unleashed another of his abilities.
