I Started Learning to Slay Ghosts in the First Seven Years

[No system + Ghost ghost recovery + Supernatural puzzle superposition + Sequence source ghost + Decisive killing + No intelligence and brainless fun, don't enter if you don't like it] I am Wang Dao, this is my seventh day traveling into this world... There really is a ghost in this world! Six days ago, I discovered that "myself" in the mirror was fading into a photo of myself... And it's getting weirder every day! They say the first seven souls return, and today is the seventh day... I feel like "myself" in the mirror is about to crawl out! In desperation, I came to this "Occult Open Class", but I got even more desperate news... Ghosts cannot be killed, only ghosts can deal with them! "Does it... Do I really have to turn into a ghost to survive?" ………… I am the king, at least I used to be... There is no hope for this world. Terror is resurrected and evil spirits are rampant in the world. There is no response to the call, and there is no god in the world... I decided to take a new path and end it all in my own way. When you read this sentence, I will be dead. This is my story after my death...
