His father once told him "Son,men who do good things get good things." 

Since that day Nox Michael became the most selfish person in the world.Helping people,volunteering,recycling and everything he could do to get good karma.All to get what he wanted.

So when he died saving someone he thought he would go straight to heaven.What happened was so much better.

Becoming an overpowered being and going to another dimension that is basically a xianxia.

"This is awesome!Normally the objective is to become the strongest,get revenge,get a harem and enjoy life.I'm already the best and nobody killed my family sooooo all I need is my harem then I can enjoy life by wrecking the bad guys and messing with people.Being selfish is the best thing ever!"
