Inside the Path of Heaven:
Yun Haoran looked at the horizon with different people coming and going. There is a special rule on the Path of Heaven that no beings can enter if they are in the secret realms or outright in a sealed state.
It is the rules imposed by Heaven because it will be broken when someone is trapped in a secret realm and they can ask for help when they enter the Path of Heaven.
It helps to regulate the balance, the inheritances, and the competitions governing the world. It also balances the quality and quantity of everyone because those who died are weak while those who survived are strong.
It is the reason for the peaceful state of the Path of Heaven where mortals enjoyed the privilege to own this place even a little bit. They have known power and manage to meet Cultivators all around the world, rather than the Eastern Continent.
They are too weak to know that the place they are in is only a small Galaxy in an unknown place.
