The reason why Lin Fan asked Sam and Abraham to wait there was not because they could not enter the space tunnel.
Instead…
If that independent space was a forbidden area, then even if Sam and Abraham went, they would not be able to help much. They would be useless. Lin Fan could deal with it himself.
If it was some other special place, it would be convenient for him to go and take a look first.
...
In the blink of an eye, Lin Fan and the Heavenly Hound appeared in the dim yellow space.
Lin Fan looked up into the distance and saw volcanoes spewing black smoke.
The air was filled with a strong smell of sulfur.
He lowered his head and looked at the ground.
The dry ground cracked continuously, and one could even vaguely see boiling lava flowing.
There were no animals or plants in the surroundings, and there was no sign of life.
This... was probably what hell looked like.
