Why had Luo Yunyang and the others come to Burial Underworld Earth this time? For the sake of the inheritance of the Second Ancient Yuan Underworld Lord, of course!
During the battle of Wanyu Sacred Mountain, Luo Yunyang had obtained victory after acquiring the Great Wide World Jade.
It could be said that the competition was over.
However, Jiuzi Xuanming came just as the inheritance was about to begin. Such actions were certainly inappropriate. It could even be said that the arrival of Jiuzi Xuanming was a direct provocation to Luo Yunyang and also a provocation to the Sky Martial Underworld Hall Master and the three other underworld halls.
The Sky Martial Underworld Hall Master's stance was tough. He was not as powerful as the Ancient Underworld Hall Master to begin with. If he did not deal with the matter firmly, he might end up being suppressed by the Ancient Underworld Hall Master.
