Rebirth After Overcoming Obstacles

[Two heroines + supernatural + campus + rebirth + no system + no space] Instead of rebirth at the beginning, you fight monsters and complete tasks along the way to gain rebirth. Xu Nannan was taken away from her life due to a car accident. Her grandmother knelt down and prayed for a piece of peace on the ninety-nine steps, giving her a chance to be reborn. The main tasks of the two female protagonists are the same, but the auxiliary tasks are different. In the process of fighting monsters, Xu Nannan and Asan developed a forbidden master-disciple relationship. Ding Ning, on the other hand, has a crush on her deskmate Shen Nanzhi. The author is still writing. If I am not good at writing, please give me some advice.
