Feng Cai'er, feeling ashamed, made a call to Yang Fei.
Yang Fei slapped his thigh and sighed deeply,
"It's my fault. I should have known earlier that ordinary police can't contend with these Mortal World forces."
The struggles of the Mortal World were perilously dangerous.
This kind of death was considered a major event in real life.
Yet, in the underworld battles, it was a common occurrence.
According to Yang Fei's knowledge, the General Police Department was overwhelmed with thousands of unsolved cases.
At least a third of them belonged to disputes and revenges from the underworld.
The next morning, Yang Fei arrived at the University Town Police Station.
The forensic autopsy results were already out.
The two arsonists' arms contained poison sacs the size of soybeans.
The poison sacs, disguised as black moles, were embedded in the skin.
Once these sacs were burst, the poison would blend into the bloodstream.
It would only take less than three minutes to cause death.
