Fang Ning's head started to ache. 'Sir System has super low emotional quotient as usual. The Black and White Impermanence were just standing right in front of him...
Qiao Zijiang did not think much, he immediately answered, "According to my analysis, the key to entering the arcane realm is on that ghostly train. The ticket might have needed bodies, but not necessarily human sacrifice. The bodies that were buried before were already dead for some time before they were buried here, and most of them died of natural causes."
