In the past, the Heavenly Law Alliance would always appear when the world was in danger. It would then protect the talented youngsters in order to provide the human race with an opportunity to rise up in the future. In this way, they were ensuring the next generation of new apex experts.
The Heavenly Law Alliance was always fighting for the world's well-being. As such, it was the last fort of the human race.
When alien-people invaded the continent and caused great turmoil, it was the Heavenly Law Alliance that sheltered all of the young experts. Such altruism led all of the people to respect the Alliance.
Even Undead Phoenix Master, Zi Donglai, and Lin Yunhe were all willing to hold offices in it, despite their having already retired. They did this because they all respected the Alliance's motto of selflessness and nobleness.
