It seems that it's different for each royal blood. It probably has to do with one's power. For example Lucaon's father got corrupted immediatly, while his mother didn't despite drinking the v solution as well. In ch 50 Cecilia said that Lucaon takes after his mother and that he will turn into a zero in about 2 months.
Why master didn't die after drinking the vs solution like his parents? Can someone help?
