The four ghost cultivators were well-aware of the strength of the western monk. Although the guy was a foreigner, the 'light of virtue' surrounding his body was thicker than that of many virtuous monks in the world of cultivators!
Such a thick light of virtue implied that the western monk had led a virtuous life and did innumerable good deeds. With the light of virtue protecting his body, no evil could harm him!
Only after leading to the right path 1000 souls could one call themselves virtuous.
Only after leading to the right path 10,000 souls would the light of virtue start to protect one's body.
But given how thick the light of virtue shrouding the western monk was... it had already undergone a qualitative change! The western monk had absolutely led to the right path at least 100,000 souls!
