Chu Fengmian slowly opened his eyes, revealing a trace of helplessness in his gaze.
The chaotic energy in this courtyard was already quite dense.
It was sufficient for some ancients or even emperors to practice martial techniques and comprehend laws.
But for a glutton like Chu Fengmian, the Nine Domains Sword Technique he wanted to practice was just too complex.
The Nine Domains Sword Technique, which integrates countless sword techniques in the world, is so complex that there is no sword technique, martial technique, or method in the entire Nine Domains that can compare to it.
The chaotic energy in this courtyard wasn't even enough to support one percent of Chu Fengmian's practice of the Nine Domains Sword Technique and was completely exhausted.
It would take at least several days for the chaotic energy to refill the courtyard.
But Chu Fengmian couldn't wait.
