In the Training Camp, rules regarding killing other disciples were lax.
The Earth had transitioned from a law abiding society where murder was heavily condemned to a civilization which was now facing invasions.
No matter what time period, murder was a crime and punished severely, previously because it was a peaceful society, and now because they needed every manpower they could get to resist the invasion.
It would be stupid to allow people to get away with murder when they were surrounded by enemies on all sides.
Here in the Cultivation world though, they were in a peaceful period.
But their society was simply so large, the population was so massive and the talent base was so vast that their viewpoint towards killing was more or less different than that of Earth.
There was also the fact that people cultivated real power here. The peaceful time of Earth and the peaceful time of the Cultivation world was different.
