I recommend Naruto: Ghost Sword Susa to you. This book described how a person who had transmigrated to the Naruto Uchiha Clan had successfully awakened the four profession skills of the Ghost Sword in the Naruto World. Although this book had no female protagonist, the author had a very toxic milk powder style. It was said to be a story that spread the glory of toxic milk powder to the anime world. If you want to catch up, the author's second world is currently being serialised-Death. I hope you like this fairy's recommendation. Muah ~π
