Why did when Ye Chen treated her grandfather, her grandfather screamed in pain, even though before when Ye Chen was treating a middle-aged man, the middle-aged man didn't look at all in pain.
It was because Cheng Huzen's condition was still conscious, while the middle-aged man was unconscious, Cheng Huzen could still feel the heat from Ye Chen's fire, while the middle-aged man who was tenuous, couldn't feel the heat from Ye Chen's fire.
That was why Cheng Huzen screamed in pain, this was caused by the heat from Ye Chen's fire.
The poison in Cheng Huzen's body began to be burned by Ye Chen's flames, little by little Cheng Huzen's condition began to improve.
Seeing that her grandfather's condition was getting better, Cheng Mengyan was so happy, she didn't expect Ye Chen to have this kind of medical skill.
In front of other people, what Ye Chen was doing was just placing his palm on Cheng Huzen's body, they didn't know what Ye Chen was doing.
