Listening to Rakuzen's words, Lucien nodded in agreement as he immersed himself in the feeling of mama surging into his veins and passing out almost as quickly as it came. Even though Rakuzen is the one controlling the body, Lucien still owns the body so he could feel everything happening to his body.
To perform this level of elemental manifestation, Rakzuen forcefully pulls the mana into his body to fuel his elemental abilities, and when he releases his power, it is greatly enhanced because of this. Lucien may know how it works but he definitely couldn't do it. First of all, he lacked the knowledge and skill. He didn't know what method Rakuzen and the emperor used to forcefully pull mana into their body at a dangerously high quantity. Even his meridians and acupuncture points were screaming out in pain after getting forced to consume so much mana but Lucien wasn't complaining since he considered this as a method of training his body.
