Tong Qin: Please Wait for Me in the Next Life

[After reading many articles, I was disappointed with the endings, so I decided to write an ending article myself. This is my first time writing a book, so try not to be OOC. Suppose Kotonoha was not killed, but fell off a cliff and was saved by Demon Slayer Hanashira. And from then on, he learned about the existence of ghosts, so he joined the Demon Slayer Corps and became a doctor, traveling after wars to treat the wounded. At the same time, Tong Mo always thought that Qin Ye had died that night, until later he saw the eyes that he missed so much in the memory of another ghost... Tong Mo, who became Icicle much later, still feels incredible about his experiences in the past ten years. And with his joining, the Demon Slayer Squad has also suffered less losses, and everyone in the original work can have a happy ending. There will be a modern if line in the later period, and the previous life will be a modern he (lifespan theory)
