"We detected an unknown toxin in her calf muscle tissue. I did an experiment yesterday, and this toxin can damage human nerve tissue, but it doesn't spread, nor is it expelled through metabolism, so it remains in place."
What Director Meng referred to as "in place" meant the calf.
Because it wouldn't spread, it didn't affect other parts of her body, and because it wouldn't be metabolized, so Director Meng discovered this poison.
This is why only the calf nerve tissue is necrotic, and other places are normal.
Qiao Xu had never heard of such a poison that couldn't metabolize nor spread.
"Have you found out what poison it is?"
Director Meng shook his head, "I've been in medicine for so many years, and I've asked several classmates who studied pharmacology, but none of them have heard of this poison."
As he spoke, he looked at Qiao Xu and asked:
"Your friend, did she offend somebody?"
