Lin Mu wore a relaxed expression.
Since it was just some aftereffects from the Elixir, it would be easy to resolve.
"Do you have anything like a Silver Needle?" Lin Mu turned and asked the middle-aged doctor.
"What do you need a Silver Needle for?" the doctor asked, startled.
"Just give me one," Lin Mu said without explaining.
"We don't have Silver Needles. Will this do?" The doctor handed over a thin surgical needle, about ten centimeters long.
"It'll do."
Lin Mu only needed to pierce the skin and blood vessels; it didn't have to be a Silver Needle.
Taking the long needle, Lin Mu located several points on Lady Su's body. He observed her ten fingers, her ten toes, her chest, and both ears, confirming he could proceed with the treatment.
Just as Lin Mu was about to insert the needle, the middle-aged doctor grabbed his hand. "What are you doing?"
"I'm treating my mom," Lin Mu said, as if it were the most obvious thing in the world.
