The result was that the number which called the truck driver in front of Leng Yecheng was the same one that called Zhang Jinhua.
Obviously, they were a group.
Afterwards, Leng Xiaoyao needed to investigate this phone number.
After her investigation, she found the person was a middleman, but he had contacted Zhang Guanglin the day before yesterday.
After a series of investigations, Leng Xiaoyao finally figured out that it was Zhang Guanglin who turned to this middleman for help. And the middleman paid the truck driver to harm Leng Yecheng.
In other words, the key person in this car crash was Zhang Guanglin, but Leng Xiaoyao didn't think he was the mastermind. There must be someone else behind his back. Who was it? Leng Xiaoyao guessed the person must be in the company Zhang Guanglin wanted to work for.
Without delay, Leng Xiaoyao investigated Zhang Guanglin's call records.
