Because I Like Master, I Turned Her into a Yandere

Double yandere heroine + reincarnation system + severe yandere My name is Shen Qingyu. I traveled to the Immortal Cultivation Continent and met the Master whom I fell in love with at first sight. I happened to have a system in my hand that could allow me to be reborn. So I decided to break Master! Just turn it into a yandere who only loves me! Jie Jie Jie... My name is Shang Yunchi, and I am the master of that idiot above. She approached me with that lustful look in her eyes from the beginning, thinking that I didn't know. I was indifferent to her at first, but it wasn't until she was everywhere around me, and there were proofs of her existence everywhere, and it wasn't until she died on the sword for me that I finally woke up. Later I discovered that I was born again. I started to treat her better and better, and I became more and more attracted to her. I found that I gradually couldn't stop. When I found that I was completely and hopelessly in love with this idiot, she abandoned me again... "Haha... Disobedient Yu'er... Just catch him..." "Master... Don't be like this..." "You don't love me anymore! Is there another master outside? No! You can only be mine... You can only belong to me! Belong to me alone!!!"
