Nah, dropped. Sealing his power just for the plot is even more ridiculous than him being teleported. I kind of wanted a super powerful ahjussi one-shotting everything like One-Punch Man and going against stronger and stronger opponents until one-shotting didn't work. What a disappointment.
I've always loathed the necessity of sleep. Like death, it puts even the most powerful men on their backs.
