章 1397: The speed of killing

The clinic was located in the High-tech Zone of Hailan city, which wasn't a bustling area. When Zhao Yu walked onto the bridge, there wasn't a single person on it.

The traffic under the bridge was not as dense as he had imagined. The cars were moving back and forth, as if they had slowed down the pace of the entire city.
