Doubtful Points! Missing or killed?

"What's the meaning of all this?" 

When Su Xuan spoke, the entire Volkswagen car fell silent. Tian Yuan couldn't believe his ears and turned to look not far away. The landlady had already disposed of the garbage and was heading back inside.

He glanced over at the pile of garbage bags, but that didn't mean Tian Yuan was unimpressed. He opened his mouth to speak, as someone in the criminal investigation department, he wasn't a fool. He just found it hard to believe.

"Are you saying that this landlady is the descendant of that sister you mentioned?"

"Are you trying to tell me that such a coincidence exists in this world?"

"Don't joke..."

The people from their criminal investigation department had been following Tang Jiajia closely. They knew very well that it took them quite a few trips with real estate agents to secure such an affordable and good property.
