Song He's approach, after all, required immense power – power enough to command the entire world.
He didn't really understand why one must endure suffering in this life to be reborn in bliss in the next... Why couldn't the world itself be easy and cheerful?
Those who had suffered, even if they later enjoyed themselves, had still experienced hardship, right? How could they be compared to those who had grown up carefree and unburdened?
Perhaps it was because the Miji God Tree resided within him, or perhaps it was his desire for such a world to exist, so he used this world as his experiment.
He had no power to change the outside world.
But here, he could.
He didn't intentionally interfere with the basic operation of the world; wolves still hunted rabbits, and birds still pecked at insects.
