With Nangong Nuannuan's explanation, what else could Sze Lingyun not know?
She had previously asked why the driver was driving so fast.
Earlier in the car, she had already advised him to slow down. Who could have guessed that the driver would say that it was not easy for them to earn money? He had to finish her trip as soon as possible, so he could get another order.
She reasoned with him and told him that even on the next job, he could not exceed the speed limit. Even more than that, he could not give up his life for money.
However, the driver had rebuked her and told her not to think that her life was so valuable. His life was also valuable! He had a wife and sick child to support. He was his family's only breadwinner, so if he died, his family would be hopeless. Therefore, money was more important to him than her comfort.
After saying that, not only did he not slow down... He sped up! Then, the near-crash happened.
