Xiao Ran's words stunned Yang Yi momentarily; he realized that whenever he dealt a fatal blow, it almost always involved slitting throats or cutting necks, without exception.
Why cut the neck? Because the neck is indeed a handy target.
The knife Yang Yi was currently using was short, just over twenty centimeters, and taking away the length of the handle, only about ten centimeters remained. To instantly kill someone with this length, one must hit a vital spot.
If a knife pierces the lung or liver or another vital organ, without prompt rescue, it can indeed be fatal. But a person who is stabbed would still have the time and strength to pull a trigger, even if death were certain. In battles where life and death are decided in an instant, these spots can't really be considered vulnerabilities.
