That is to say, this channel was only open for exit, not entrance. The six ghost gods could escape the Netherworld from this channel, but it wouldn't be easy if they wanted to return.
With a flicker of thought, Jiang Chen followed into the Netherworld with the flag in his hand, shadowing the six ghost gods closely.

As soon as the six ghost gods escaped the two worlds channel and entered the region of Qingcheng Mountain, they were greeted by several heavenly gang-thunder as thick as water vats.

At the same time, Jiang Chen exited the two-world channel, shook the Netherworld flag in his hand, and gathered the immobilized six ghost gods with swathes of innate Netherworld divine light.
"Six friends, let's get going!"
