Upon hearing this, Yun Sheng couldn't help but feel a sense of amazement in her heart.
The advancement of her second uncle, as well as the Heavenly Thunder Body Refining, was very likely due to that Nine-leaf Purple Ginseng from earlier.
When the Nine-leaf Purple Ginseng advanced to the Nine-leaf Divine Level, it had also attracted Heavenly Thunder, but at that time, because of Yun Sheng and Ye Beiming, the Purple Ginseng had only absorbed a small portion of the Thunder power.
But later, it was used on Yun Canglang, and with the dispersion of the Divine Power, it coincided with Yun Canglang's advancement, and that portion of Thunder power brought forth several Heavenly Thunders.
Even though she knew heavenly thunder had benefits, the thought of her and Ye Beiming's past encounters with thunder strikes filled Yun Sheng with fear and trepidation; she was worried about the safety of her second uncle.
