Back in Ancient Times, He Was a Ghost

What am I? This was my biggest doubt when I returned to ancient times after my car accident. What what? Am I a "half-soul"? What what? Can I be reborn? ********************************************* I just wrote a story that I have been thinking about for a long time... My writing skills and expressive skills are not good... So the adults who read the article are disappointed... Also~ if you have any suggestions... You can put them forward~~ Finally, thank you to those who cheer for me and read my articles~~ PS: We are about to take exams recently~~~so the update speed will be slower~~Thank you again for your attention~! ! ! ----Kunbugege
