"How can he possibly be asleep?" Tang Yuxin stopped in her tracks, noticing Gu Ning's slowed breathing. He really was asleep, probably from sheer exhaustion.
Tang Yuxin then got up, fetched her needle package, pulled out a needle, and with a slight move of her fingers, inserted the needle into Gu Ning's back, then took a glass jar and attached it to the needle.
Before long, she could see dark blood seeping out from the needle tip.
This indicated a worrying state of health.
It wasn't until half an hour had passed that Tang Yuxin removed the glass jar and wiped away the dark blood, then covered him with the quilt. It was already approaching midnight.
Fortunately, Tang Yuxin thought about her own situation; she was on the late shift tomorrow. If she had been on the early shift, she might not have managed to get out of bed in time.
