Xia Fan's logic was simple: I'll be nice to you if you're nice to me. If you're bad to me, I'll send you to your grave!
There had been no good men under the skydome, and while the scoundrels of the Holy Tomb had wanted Xia Fan to be a good person, they were also worried that Xia Fan would lose out if he came across people with wicked intentions.
That was why they had instilled two educational programs into Xia Fan. One was how to treat his friends, and the other was how to deal with his enemies!
There was nothing much to be said about how he should treat friends. Treat them with equal respect, and if they offered him a drop of kindness, repay them with a spring of grace.
