Chapter 221: Asking Mr. Fang For Help

"Neurotoxicity?"

Zhang Sa was shocked.

Yu Gangan nodded her head, "He must have taken something that has a strong effect on his nervous system. This medicine must only target the nervous system and have little side-effects. So, even though it can't be detected in his bloodstream, the toxicity has been accumulating in his body and slowly damaging his nerves."

"What medicine has uncle been taking?" Zhang Sa immediately asked her auntie.

Auntie Zhang replied in a panic, "Just some Chinese medicine that you prescribed for replenishing the body. He stopped taking his Western medicine after he recovered."

"Do you have any left over?" Yu Gangan asked.

"No," Auntie Zhang said as she shook her head.
