However, Xun Qu wasn't too curious about such martial arts. Although practicing them seemed impressive, the risks were equally great, much like the Five Thunder Body Casting Technique. This was originally a sect-defining martial art of a major sect. Later on, the powerhouses of that sect all perished under the heavenly thunder of the Five Thunder Body Casting Technique. In the end, that major sect was completely obliterated. Therefore, any martial art with obvious downsides isn't necessarily a blessing.
Take the current situation for example: martial arts that invoke heavenly thunder boast tremendous momentum. But aside from Shen Changqing, anyone else who tried to cultivate them would likely meet their demise.
Watching the heavenly thunder outside the city, Xun Qu observed it intently for a moment but chose not to intervene further. If the other party had left voluntarily, they must have had their own plans. Meddling too much wouldn't necessarily be a good thing.
