When Ning Yue heard this, she said indifferently, "Isn't it just cutting open your wound, digging out the arrowhead, and stitching up the wound?"
Gu Yu knew that Ning Yue was not telling the truth. He knew his injuries very well. The wound was so deep that it would take a lot of effort to treat.
Most importantly, if he were to handle it, he wouldn't be able to keep a person still while stitching up the wound.
He was so badly injured and bleeding too much. Even if he woke up, he should be lying in bed. If he moved, he would be dizzy.
However, that was not the case now, and he could not sense any use of blood replenishment medicine, so he had a bold guess that Ning Yue had replenished his blood!
Then where did the blood come from? He indirectly mentioned the blood loss to the Ning family. The Ning family was very confused. In other words, Ning Yue had given him her blood so he could recover.
