Zhao Xinwen's office floor had dozens of offices, and Gao Yang had fired over a dozen shots. He hadn't expected not to be discovered, but when he stepped out of the office, he found the corridor silent, even the doors that were originally open had been closed.
Gao Yang had intended to use the stairs to go down, but when he saw that an elevator was descending and about to reach the 18th floor, he pressed the call button with a calm face. As the elevator doors opened, Gao Yang entered with an inconspicuous smile.
There were seven or eight people inside the elevator, completely unaware that a homicide had just taken place. Gao Yang rode the elevator as it stopped at each floor, quickly arriving at the lobby on the ground floor.
