Wu Lingyu obtained a mysterious power that she didn't know how to use, but fortunately there was a book that could guide her. In the process, she met a person who looked cold and fierce on the outside, but was actually so gentle and a bit introverted on the inside.
What Wu Lingyu had to do was to advance, from level one to level 12. Level 12 was the full level, and he would become stronger. Wu Lingyu also made many friends, and spent every day with him through difficulties.
Intention: When doing anything, you must overcome difficulties
