Guan Kang held out his hand.
"Please take it easy. You can squeeze out some blood with a needle! My blood has been taken previously to verify if my blood is effective, so my body is still a little weak. Please take a little blood from me to verify if my blood is really effective!"
This made everyone inexplicably sad.
Even the woman who had just walked over suddenly felt her eyes sting. She felt a little uncomfortable.
"Let's do as he says and take some blood! I think this child's face is pale. If we really take too much blood, he'll die!" Jade Face said.
The leader nodded and called for someone to bring out a silver needle and a clean porcelain bottle.
Blood quickly flowed out of the silver needle.
After squeezing hard and collecting a small bottle of blood, these people let go of Guan Kang.
