บท 144: Mutually Beneficial Relationship

Recalling those days, Yao Ran licked her canine teeth and felt the urge to kill almost take over her sanity. She took a deep breath to calm herself down before she lost control.

After spending two years as an experimental subject in the laboratory, Yao Ran found it difficult to stay sane whenever her feelings fluctuated too much.

In her previous life, she could only hurt herself to control her killing instinct and retain her sanity. 

However, when she faces enemies or people with ulterior motives who want to harm her, her instincts seem to take over her mind, and she is unable to control the urge to kill. At that time, she will become a mindless killing machine.

After calming down, Yao Ran nodded to Grandma Quan and said, "Thank you, Grandma Quan, for coming to tell me all of this."

Yao Ran knew that Grandma Quan told her this not only because they were on good terms but also because Grandma Quan knew that her family needed their protection.
