Three days later, Su Yan came to see me.

He looked the same as usual, but I found him more pleasing to the eye than before.

"Thank you for helping me, I've been sleeping well these days," I said.

He was relieved, "Do you know when a doctor is happiest?"

I was puzzled.

He said, "It's when their medical skills are recognized, and their ideas are successfully verified."

I vaguely understood.

He hummed a tune as he turned around to tidy up the files.

I brushed my long hair forward to cover my ears, greedily staring at his back.

His body filled me with desire, a desire for slaughter.

Su Yan didn't know that the knife had missed, and I didn't die.

Now, I have killed Li Xiaoying, completely residing inside her body, controlling her consciousness.

For the rest of my life, I am Wang Fan, coexisting with Li Xiaoying.

Epilogue

Su Yan was so excited that he wanted to dance. The treatment was successful, and the research project he had devoted himself to for many years had finally become a reality.

He was convinced that the human mind could be controlled.

Back then, his mentor always poured cold water on him, holding back his thesis from being published, not even allowing it to be mentioned.

After so many years of being unappreciated, he was finally able to hold his head high today.

That day, he rolled out of the window with Wang Fan in his arms, and the saw cut open his stomach, but his knife only stabbed under the opponent's ribs.

After drowning Tang Yue, he remained alive for a while before slowly choking.

Fortunately, Wang Fan remembered clearly the last words he whispered in his ear: "Kill Li Xiaoying, and you'll be able to live forever."

From Li Xiaoying's recent action of covering her ears, it seemed Wang Fan had returned.

Su Yan sat in his spacious office, proudly opening his thick research paper.

The first line caught his eye.
