The Dried Corpse Elder looked at the Underworld Monarch before him and said with respect, "Don't worry your highness, I'll go and get Qingfeng's head right now and avenge our young master."

The Dried Corpse Elder's body turned into a cloud of black fog as he disappeared immediately. The Underworld Monarch closed both of his eyes, as he continued to train there. 

The Underworld Monarch had already received news. The Crimson Fire Monarch had already reached the half-step saint realm and was trying to understand the Saint's Law. Once the Crimson Fire Monarch completely understands the Saint's Law, the Crimson Fire Monarch would then reach the saint realm.
