Jiu Yi hurried to fetch it. The needle bag was in the medical box, and he found it after a quick search.
When the needle bag was opened, a row of gleaming silver needles was revealed.
"Jiu Yi, take off his clothes," someone instructed.
Jiu Yi immediately complied, while Wen Lao took a needle and sterilized it over a flame.
A moment later, Wen Lao meticulously inserted needles into several vital acupoints on Yu Chiyin's body. A faint sting spread as Yu Chiyin's body twitched slightly.
Jiu Yi watched as droplets of black blood slowly oozed out of the needle sites, his face showing surprise.
When the time had passed, Wen Lao carefully removed the needles, one by one, and exhaled in relief,
"All done, Jiu Yi, help him wipe it off. Be careful, the blood droplets are poisonous. Do not touch them."
"Yes."
Jiu Yi took a handkerchief and carefully wiped away the droplets of blood.
