Having worked at the Edge of the Universe for two years, Ji Changsheng had learned many things.
For instance:
Always stand on the side of justice.
Always stand at the moral high ground when dealing with others.
Always represent justice.
Only in this way, one can be invincible.
Therefore, he had to seize the moral high ground first and become the person who could interpret justice.
The Disciples of the Mystic Temple had this right to interpretation.
So did the Danqing Pavilion Disciples.
The Devil Sect did not, which is why Ji Changsheng despised the Devil Sect and didn't want to join them at all. It was others who forced him to do so.
Now, Ji Changsheng continues to represent justice as before.
