Ghost Zhu's Blue flame wasn't ordinary, it was hell Ice Fire. Hell Ice Fire was a type of extremely Yin Fire. No matter what it touched, it could instantly freeze it and turn it into ice powder. It was extremely overbearing.
Zhu Gui had obtained this flame by accident. Although the nether Ice Fire was extremely overbearing, he didn't use it often because it was too overbearing. Although the fire weaving tribe had a special technique to control fire, the more overbearing the fire was, the harder it was to control it. Even though Zhu Gui already had the nether Ice fire's flame seed in his body, using it for a long time would still cause his meridians to be affected.
He was an expert in the longevity stage. Even such an expert could easily injure his meridians when using the nether Ice and Fire, let alone others. This nether Ice and Fire could be said to be Zhu GUI's trump card.
