It's been said that Ma Zi is dead, but Yan Fei didn't even ask whether you all suspected him.
It's pretty obvious—if they really suspected him, they wouldn't just call him. They'd probably directly invite him over to assist in their investigation.
The police station's call was just routine questioning. No matter who the deceased was, since it's a murder case, there has to be a result. That's their duty; they can't just ignore it because the deceased happened to be a scumbag everyone wished dead...
Honestly, anyone could guess what happened—Ma Zi most likely carelessly revealed that he had two hundred thousand yuan, which led to his demise. As for suspecting Yan Fei, that's impossible—just this afternoon, the news aired a story about Boss Yan. Yan Fei, a renowned entrepreneur from our province, donated research equipment worth millions to a prestigious research institution in the Capital.
