Wei had taken into account that even if he destroyed his phone, Mo Huojin could have already memorized her number. So, if he managed to escape under an exceptional case, he could just buy a new phone and sim and still contact Lihua. So, the only way was to destroy Lihua's number. There was another option by which Lihua could buy a replacement sim with the same number. But he would be there not to make that happen.
As for Lihua, he was pretty much sure that she hadn't memorized Mo Huojin's number. She wasn't that type. There was also the thing that they knew each other's addresses where they lived, but he decided to take care of that matter too.
So in this way, a jealous Mafia King cut off all the sources of Mo Huojin and Lihua contacting ever again.
When Lihua came back, she was stunned to see her phone lying on the floor. "What happened to my phone?"
Wei sincerely said as he lowered his head. "It's my fault. Your phone slipped from my hands and it broke a bit."
