The effectiveness of the Devouring Whale Technique exceeded Shen Zhui's expectations!
Contrary to his anticipation, the Red Sun Nine Dragons Picture Technique did not conflict with the Devouring Whale Technique. Instead, this top-tier body cultivation technique, thanks to its solid foundation, offered ample scale for the operation of the Devouring Whale Technique!
The width and toughness of one's meridians, the capacity of one's acupoints, dictate the effectiveness of the Devouring Whale Technique. A typical person using this supplementary technique, even disregarding the issue of whether they could withstand it, would be limited by the aforementioned conditions.
If certain special techniques did not open certain acupoints in their body or unblock certain meridians, and the operation of the Devouring Whale Technique required that specific meridian, a conflict would arise, and the absorption effect would be compromised.
