The streak of purple thunder Jiang Hanyun saw was none other than the 'Purple Mansion Celestial Thunder' unleashed by Li Xuan.
This talisman from the Tianshi's mansion is worth 1,200 patterned silver. Yet its destructive power is quite astounding. Consequently, after it was triggered by his Thunder Style Zhenyuan, its effectiveness slightly increased.
A tenth of the 'Pregnant Ghost's body was scattered by the incoming thunderbolt, while Peng Fulai, who was utilizing a talisman, caused its 'Chiyuan God Fire to burn the Pregnant Ghost' from the inside out.
The four men present were scared that this evil spirit would be chased away. However, their weak cultivation likely made the Pregnant Ghost feel unthreatened. The evil spirit, initially floating above in the air, was luckily lured down as they wished.
