"Director, we've found it. The property management of the Xin Rui neighborhood told us that a resident on the first floor of his neighborhood dug up a basement secretly under his house seven years ago, and the area he dug up was even larger than his house. Several relatives of that family worked as cement workers at night. They were all dug secretly at night, but later they were found to have been reported and dealt with as well as the property management..." Qin Qin Ting told us that they would report it as soon as there was any news, so they couldn't act rashly and alert the enemy. Therefore, when they found something, they came to ask Qin Qin Ting for instructions.
The policeman said that he had dealt with the property management department, but he did not say exactly what he had done. Obviously, it was impossible for him to do too much. If other residents in this building knew about this, it would be a big problem.
