Xie Pinggang was not a fool. He knew that the killer could not have bought the silver ring powder himself. As long as it passed through someone else's hands, it would be easy for him to push the responsibility to someone else. He did not know how many times he had handled similar cases.
It would be difficult to catch the real killer.
Staying here was just a waste of time. It was better to go back and start investigating the silver ring powder again.
"Yes," Xie Pinggang agreed straightforwardly. He asked someone to capture the granny and take her away.
Xie Qiao did not stay any longer either.
After leaving the Dong Residence, Xie Pinggang spat, "F*ck you!"
"I understand that you've lost your wife. But in front of your sister, you should speak more elegantly. Don't startle her." Zhao Xuanjing glanced at Xie Pinggang silently.
