Li Zhongnan didn't ask for the rationale, he simply wanted her to tell him what he should do. Soon, Sun Ruiyan explained the process to him and handed him a copy of "Dragon Whale Breathing Technique".
According to her description,
this breathing technique was a culmination of the Beast Taming Sect's numerous experts' efforts, based on the respiration of the Dragon Whale Divine Beast, and established through countless deductions and validations.
Even when compared to the entire Eastern Mainland, the sophistication of this breathing method ranked within the top ten. Its training speed surpassed that of ordinary Elemental Warrior Techniques by several times!
Of course, in this aspect, Li Zhongnan was an idiot; he was utterly insensible to these matters.
In fact, he wasn't so eager to become stronger or to cultivate, but was mostly driven by curiosity.
After all, it was something new!
