The Grand Tao is fair, the Great Tao is simple.
For any heaven and earth, it treats all beings nurtured within it with extreme fairness and equality.
No matter whether the creatures between heaven and earth are strong or weak, in the will of the heaven and earth, they are all their own children, and there will be no bias.
However, for most worlds, unless it's a world that is inherently intended to nurture evil and killing, the majority of worlds will need to prosper and grow, which requires the constant prosperity of the world itself.
The battles and killings between cultivators, the fights among mortal martial artists, for the heaven and earth, are mostly a great burden and will affect the steps of the heaven and earth's advancement, delaying the speed of the world's growth.
