Four days. Lex meditated for four continuous days, doing his best to calm his mind. There were still a few issues here and there that required his attention, but since they were not emergencies, he ignored them.
Unfortunately, despite how critical the situation was, there was nothing more important than getting control over his own mental state. Lex could not even imagine the consequences of what would happen if he developed a Heart Demon while he was learning the Masterless technique.
The very fact that it took him four entire days to regain mental clarity and regain control over himself was a testament to just how incredibly stressed he really was. Maybe he had been dealing with his stress and dangerous situations for too long, and this was a sign for him to take things easy for a while. Unfortunately, whether he took things easy or not was not in his control, at least for now.
