Do you know anything?

Under everyone's shocking gaze, Xie Ming carefully started putting the needles on the horse. 

She doesn't want to remove the effect of the drug fully with the acupuncture since she doesn't know what kind of drug it is and Grandfather Su has also told her earlier to not use needles carelessly when you don't know anything about one's medical history or the composition of any drug given to them.

So she only put the needles on the safe spots which will only reduce the effect of the drug and will not eliminate it fully.

She was planning to give him some medicines which will slowly remove the remnants of the drug from his body.

The sun was blazing and she was sitting beside the horse under the blazing sun and was treating him.

Everyone else has taken shelter under the shade which was on the corner. 

Jiang Yan pursed his lips and walked to her. He doesn't have any umbrella with him, so he just stood behind her, protecting her from the sunlight.
