Having dealt with the Task Taker, Anning could well complete the task.
She had originally planned to vacation in this world.
She thought of vacationing, learning some skills along the way, and then incidentally completing the task.
But, the very next morning, An Xin returned.
"Ningning, the Main God has discovered issues with this world. The disappearance of a Task Taker has alarmed the Main God, and soon many Task Takers will swarm here. Also, I've found information about a small world you once were cannon fodder in, and it's been tagged. Whenever you want to go there."
An Xin knew what Anning's greatest regret was, and what she most wanted to do.
Anning's most desired actions were to take revenge on the Main God and to find those small worlds where she had been cannon fodder, to live in them of her own free will, without anyone else's control.
And An Xin had always been helping Anning search for those small worlds.
