And the results are?

The Heavenly Dao exists.

It decides what is right and what is wrong. To act against it is to sin, to act according to it is to be blessed by its graces.

The world of cultivation is difficult, an unchanging principle. Yet there are those who are cherished by the Heavens, cuddled into rising above all and everyone else. How can this be? Why must this be?

What is moral and just? What is evil and immoral?!

WHY DOES IT GET TO DECIDE?!

So we, the Sinners, we act against the Heavenly Daos, grasp our own fates in hopes of truly overturning them.

This is a Journey of a young boy born Blessed, but turned Sinner.

The greatest sinner of them all.
