There’s one thing that I am trying to comprehend after reading the latest manhwa chapter. At some point in the story, two of the inheritors fought over the Black Infernal Tower in the ancient past, with one dying and the other becoming wounded. It is likely that Kong Yan was one of the experts that fought over the Black Infernal Tower when it was formed. Now whom was he fighting against and who died among those two while the other was wounded?
Since Nie Lie is out of the question, only 3 Suspects remain: The Mysterious Old Man, his younger brother and the Unnamed Inheritor from the Ancestral God Land. Does someone know the answer to this question?
Note: During the Lord of Nether's Disciple Selection the Celestial Qilin recalls that he was chained up in the tower by an "insane old man." Since we already learned that the tower was originally fought over by two of Kong Ming's successors it might have been the Mysterious Old Man that locked him up, however this cannot be the case since the Old Man stated himself that he has already killed two successors of Emperor Kong Ming. One of them is from the Ancestral God Land, and the other is his younger brother. Hence he cannot be the one who fought Kong Yan as that would mean that that he killed 3 successors.
