When An Ling was traveling with her parents, she encountered an accident and got an elf that only existed in her mind - Ripple.
The elf told her that if she wanted her comatose parents to wake up, she could only follow her to do tasks in different small worlds. The goal of the tasks was to change the fate of the relevant characters, but it could not change the known historical context.
Every time she completes a small world task, she can get very generous rewards.
Out of concern for his parents and the temptation of generous rewards, An Ling started traveling through time and space again and again under the guidance and cooperation of the elf Ripple.
She was mentally prepared that every mission would not be too easy, but she never expected that every start would be a disaster...
