The Two Elders of Ling Nan did not dare to conceal any information at all in answering Ning Fan's question. They could only tell him every single detail about the entire event.
It turned out that the reason why the red-haired lady pursued the two was purely because of an accident.
The two were Void Inquiry Stage old monsters who had been searching and exploring historical remains of ancient cultivators throughout the years. In their most recent trip where they checked out an ancient place that was used by cultivators in the past, they accidentally discovered a passage leading to another realm that was filled with immense killing qi.
It was unknown as to what realm that passage would lead to. However, it seemed to be connected to a broken and worn out small chiliocosm.
