What a pity.
Although the Mixed Element Skill is strong, it does not contain the methods of 'breaking the limit of Qi and Blood' or 'Qi Blood Refining'. This 'Mixed Element Skill' didn't come out of thin air but was deduced by Yan Chuan through learning and accumulation; all its content is what Yan Chuan has either actively or passively understood and mastered.
Yan Chuan doesn't know the methods of 'breaking the limit of Qi and Blood' or 'Qi Blood Refining', so naturally, the 'Mixed Element Skill' doesn't include them.
"Martial arts cultivation, different paths lead to the same destination."
"Perhaps."
"When I cultivate the 'Mixed Element Skill' to a profound realm, and my inner strength accumulates more abundantly, nourishing the flesh and driving the growth of Qi and Blood, I may naturally break the limit."
It's not impossible!
