Xiaoxiao took her medicine, and the two of them returned to the rental courtyard. There was nothing out of order in the house, everything was the same as they had seen yesterday.
They went over to the courtyard wall and examined the interior and exterior areas, discovering numerous footprints on the snow piles. Xiaoxiao's eyes lit up, "Yang Ming, look!"
Yang Ming analyzed for a moment, "There are many footprints, and they're disordered. There must be at least three people."
"And the footprints are large, they must be men's."
But other than the footprints, no other clues were left behind, and Xiaoxiao's bright eyes soon dimmed again.
"Xiaoxiao, don't get upset! There will be a way, that packet of medicine is a clue! We can start the investigation from that medicine!" Seeing his wife's disheartened look, Yang Ming was worried she might despair.
