The first time he traveled through Mu Qing was to an ordinary family during the Warring States Period. On the first day he traveled through the family, his family was killed by a ghost. Then he resolutely joined an organization called the Demon Slayer Corps [because there was more money]. Later, he discovered that the brother of the boss who taught them breathing techniques had turned into a ghost, and then he passed through it.
The second time he traveled through time, Mu Qing became an older brother named Lian Xue Girl, and he also had a prospective brother-in-law named Komaji. One day, his brother-in-law went to visit the grave. When he came back from studying medicine, he saw his father and sister dead. The brother-in-law massacred the dojo next door for revenge. He also saw his brother-in-law walking aimlessly like a corpse and was turned into a ghost by Onii Tsuji Mumis, and then he wore it again.
The third time Mu Qing traveled through time and became the young master of a wealthy family. One day, friends and friends invited him to Flower Street. He got lost while walking and met a pair of brothers and sisters named Prostitute Taro and Mei. Then Mu Qing became the master of Prostitute Taro. One day, the apprentice did not come for training. Mu Qing later learned that the apprentice turned into a ghost, and then he wore it again.
After traveling through these several times, Mu Qing felt deeply powerless, and finally decided not only to kill the evil spirits, but also to bring back the careless ones one by one.
Ps: There should be private settings, the writing is not that good, and the updates will be random.
Intention: I hope the ending is happy
