The channel between the Small World and the Immortal Cultivation World was not kept open at all times by Cultivator Shen Yu.
After all, even though the consumption of Gray Mist by experts passing through had already been greatly reduced, frequent movement back and forth would still accumulate considerable expenditure.
And Cultivator Shen Yu also had a reasonable excuse for this.
Every time a powerful figure passed through, it would bring the Extraordinary Laws of another world, and over time, this would cause a certain degree of pollution to the still fragile Small World.
In such a situation, unless absolutely necessary, passage had to be minimized as much as possible.
Of course, anything below the True Master level didn't matter.
Once this world leveled up further, Earth Immortal passage would no longer be of any concern.
