Since Pan Shi could barely preserve his own life at that time, he naturally wouldn't have had the ability to counterattack those living beings. Consequently, though there was no trouble in the short term, without the ability to fight back, it was unlikely that Pan Shi could consistently ensure his safety from the enemies' hands.
Therefore, based on the situation at that time, unless Zhou Tian took action to help, even if there was no trouble currently, it was likely that if time dragged on, Pan Shi would inevitably die at the hands of those living beings.
Was Zhou Tian capable of saving Pan Shi at this moment?
If that formidable opponent hadn't existed, given Zhou Tian's ability, he would have protected Pan Shi. No matter how powerful those living beings were, it would have been difficult for them to gain any advantage over him.
