"However, what I still need to figure out is whether this world has already been invaded and destroyed, or if it's currently being invaded, and whether the invader is the Mysterious World."
If it's a world that's already destroyed, just like the Heavenly Dao Continent, or like the Hero and Demon King instance, then Mu Rufeng can make a resolute decision.
But if not, if it's a real world, then Mu Rufeng....
In an instant, Mu Rufeng thought of something, a notion popped into his mind.
"Damn it, wait, could it be...." Mu Rufeng was shocked inside.
He considered, if this world is real and hasn't been invaded, and then the task assigned is something like opening a passage to the Mysterious World.
Then, Mu Rufeng couldn't decide whether to complete the task, and the task probably wouldn't have a time limit.
So Mu Rufeng stayed in this world continuously, which also explained why Tang Xinhe, who reborn three years ago, and Mu Rufeng hadn't returned and remained in this world?
