"But how did I get poisoned?" The driver looked at his tightly bound wrists, certain the poison couldn't have spread from his hands.
"You just sucked the blood from the back of your hand," Xiaoyun said, looking at the driver with her big eyes. "You might have accidentally swallowed some of the poisoned blood."
"No way, right?" The driver's eyes widened. He wasn't stupid, so how could he have swallowed poisoned blood?
"Then are you prone to inflammation?" Shi Yazi suddenly asked.
"Inflammation?" The driver was baffled.
"Yes, inflammation," Shi Yazi said. "Do your gums bleed when you brush your teeth?"
"That does happen," the driver admitted.
"That's it, then. The poison must have seeped in through your gums," Shi Yazi said.
"So, I sucked on my hand for nothing?" The corner of the driver's mouth began to twitch again.
"Definitely for nothing," the siblings said in unison.
