I'm in Europa, My Girlfriend Is Killed at the Beginning

During a trip, Chen Changxing's girlfriend was shot dead. In order to find and avenge the killer group that killed his girlfriend, Chen Changxing learned from his father's method of dealing with competitors when selling pig's feet rice, and adopted the simplest "business war" - Use the lowest price to grab all the killer group's business, and use the fastest speed to kill all the killer group's potential targets.

In this way, killing and killing, the team led by Chen Changxing gradually became the most disgusting "Mixue Ice City" in the killer world!
