Luo Sheng was injured because he had gone to see the investor of 'Derivative'. So, it only made sense for Tangning to speak to this man by the surname of Luo.
But, according to the initial investigation of the police, Luo Sheng was attacked before he even arrived at the man's home. As for the reason why he stopped his car halfway and what happened during the time that he stopped, the police had no way of finding this out. After all, it was a rainy day, so it was hard to retain evidence. Plus, that particular stretch of road had no government-issued surveillance cameras.
If Luo Sheng couldn't tell them what happened, no one would ever know the truth.
The next day, news of Luo Sheng's 'disfigurement' quickly spread throughout the city. An artist that had a promising future was suddenly disfigured; wasn't the timing too coincidental?
