"It's none of your business."
"Is it poison?" The old doctor adjusted his glasses, "This red is really deep, it must be very pure, right?"
Luo Xiao ignored him. He stood up, walked to the trash can, forcefully broke the head of the test tube, and then used a disposable syringe to draw in the deep red reagent.
The old doctor kept a close eye on his actions.
With a grim expression, Luo Xiao walked to the bedside holding the syringe. He didn't inject it directly, but aimed the needle at a potted plant beside and pushed the plunger to let a few drops trickle down onto it.
The originally green potted plant instantly withered and decayed. In just a few minutes, the entire plant shriveled to the point where even the roots were invisible.
A wisp of black smoke rose from the blackened soil.
The old doctor widened his eyes at the sight, almost unable to speak in shock, "De... Devil's Kiss..."
Luo Xiao turned his head to look at him, "What? You know about it?"
