Despite being thoroughly familiar with the technique, Lex continuously practiced it for over an hour. He practiced gathering the Qi for Qi Repulsor on various parts of his body, from his palms to his chest to his legs and even his forehead. Only when he was completely drained of his Qi did he finally stop.
Tired and sweaty, Lex went and took a nice long shower, before he re-equipped the Bathrobe and returned to the Meditation room. Sitting cross-legged, he started cultivating using Regal Embrace.
Each cultivation style was different, and would slightly transform the absorbed Qi into the unique form of Qi each cultivator contained within their body. For people who had affinities, such as Will Bentham who had a water affinity, the Qi or spiritual energy they stored in their body would be more concentrated and special. The Qi in Lex's body, though, was on an entirely different level.
