Please recommend an old horror movie that mainly portrays a monster.

I recommend "Hell Games", a mystery detective novel, to you. Although the plot doesn't completely match your description, there is an evil eye that monitors the protagonist, Anli, and gradually controls his thoughts, making him have the urge to kill. There are also murderers who kill people who are enemies of the protagonist. The plot is similar to the monster killing you described. I hope you like this fairy's recommendation. Muah ~😗

I recommend the urban life novel "Send a Red Envelope to the Future" to you. The main character of the novel, Wu Haoren, unexpectedly received a future red packet system.

I recommend "Old House Ghost". This novel is a modern romance and urban life novel. It tells the story of the female protagonist Guan Xiaoqin writing a horror novel. She visited many places with supernatural legends and had a thrilling experience. This book takes the form of a collection of stories, showing their kind and simple feelings.

Ah, you scared me!😱However, I happen to have a book that I can recommend to you. It has a full score on the horror index and is called " Hell Movie Theater." The plot of this book was quite exciting. It was about an office worker who picked up a mysterious movie poster. As a result, he was involved in the plot of a horror movie and had to play different roles according to the script. Only by saving up enough death redemption coupons could he leave the Hell Movie Theater. This book was different from traditional horror novels. It was a variant of the infinite style + fantasy + supernatural style. It would definitely make you unable to put it down! I hope you like this recommendation and don't cry after reading it.💕
