How many years were you reincarnated? If you believe in western myths, the longest is half a year. Legend has it that heaven will be full, and it will be full one day. The angel in charge of metempsychosis will let the soul of the waiting person return to earth and stay for half a year. But you can't tell who you are. It's almost like a movie, but I forget the specific name. It's hard to say if you believe in oriental myths. Oriental mythology pays attention to the causal cycle. You have done a lot of bad things, and you need to pay your debts slowly and accept punishment in hell. If you know how to pay, you may never live beyond life.
