During that time, Qi Zhaofeng changed his surveillance position two or three times but didn't dare to enter the inn.
It was not until over two hours later that he finally lost patience and left.
Ji Xinghuo still hadn't moved until Qi Zhaofeng was more than 500 meters away on another street according to the magnetic field sensing, then he slowly walked out of the inn and followed.
The maximum range of the magnetic field sensing was about 800 meters, so there was no fear of losing track.
Tracking someone over half a kilometer apart in the city with such dense crowds was almost an impossible task.
But for Ji Xinghuo, it was as easy as turning over his hand.
Qi Zhaofeng arrived at a station and soon boarded a steam bus.
Ji Xinghuo could have caught up with the bus if he ran, but he didn't have any invisibility powers and running in the street was too conspicuous.
He walked briskly for several dozen meters and entered a horse shop on the street side.
