It seems that I haven't made the question clear enough. Assume that if it requires 1,000,000 exp to get to lv99. So now, I have 1,500,000 exp and after I rb, I am only lv5 but supposedly I should have 500,000 exp left and should not be only lv5. do I have any misunderstanding to the rb system?
PS. of course I know I will have 100c in return.
