The True Spirit is renowned for being difficult to kill. Of course, with Ning Fan's current mana, refining an ordinary True Spirit to death is not too difficult a task.
The truly difficult ones to kill are Exotic True Spirits. These True Spirits often require special means to be eliminated and are extremely troublesome.
Ning Fan once encountered an Exotic True Spirit of the Dragon-Horse Clan. At that time, the sixteen Dragon-Horse princes shared a heart, and it required capturing all of them before they could be refined and killed; while a single Dragon-Horse True Spirit, astonishingly, could not be extinguished even by the Refining God Cauldron.
To deal with the Dragon-Horse True Spirit, Ning Fan had no choice but to buy a copy of "The Complete Analysis of Chaotic True Spirits" from the Tongtian Sect, from which he found a strategy and finally refined the Sixteenth Prince into a pill to swallow, greatly advancing his cultivation.
