Su Jinnian personally took Shen Ci through a special passage to get an X-ray, and they found a hollow needle under the tissue of that red mark.
They extracted the needle for analysis, which contained a chemical agent that could damage nerves.

Shen Ci couldn't help but scoff coldly. To deal with him, they really devised quite a plot.
But this time, he really owed Meng Chuyue.
If she hadn't reminded him, he would definitely be at home sleeping right now.
