A defeated smile curled Lai Mingjie's face as he heard his wife sneered about his sleeping habits again. Well, he couldn't blame Xu Rouguang if most of the time Xu Rouguang was at work, he was in the hotel room. As long as no one disturbed him, Lai Mingjie would continue to 'sleep' as if entering a dead state while sitting cross-legged on the bed. There was one time that Xu Rouguang left him alone for three days, and Lai Mingjie barely realized it.
Cultivation would not be the word to be used for it. He was not trying to gather energy to nourish his body and make it stronger after all. Neither was he taking in energy to fill his demon core. Technically, Xu Rouguang couldn't figure out what was happening to Lai Mingjie as his senses would be deflected by the 'dead state'.
Alas, the petty wife only described it as sleeping.
