This is impossible. According to my calculations, you need to will need at least 18620 minutes or 310 hours or about 13 whole days to watch the entire series of one piece. Since One piece has currently have 931 episodes which each may have AT LEAST 20 minutes (an average anime episode last 23-25 minutes) which would be impossible to watch in a single 24 hours even you skip half of the series as skipping the fillers.
