[Volleyball Boy/spell Return] I Stand on Top of Millions of Lives

What is life? It is the cry of new life. It's the old man's sigh. To Huashanyuan Hegui, it was just a string of numbers. /// Since opening his eyes for the first time a thousand years ago, Huashanyuan Hegui has begun a drift that lasts for several eras. If my footprints can travel across mountains and rivers, if my name can be known by thousands of people, if my existence can subvert the world's perception... What if... I was like today, hiding under the rotting carcass of the magic world. The world is God's playground, and every step is a grand gamble that never looks back. "So life is really a miracle." Improper introduction: A certain blueberry brain: She is my grandfather's friend. A certain orange puppy: I thought she was the big sister. A certain fox volleyball team: So why did she study for two years as a freshman in high school? Some kind of robot: Grandma is... I don't know if it's appropriate or not, but grandma respects her very much. Crowd: So how old are you this year? Huashanyuan Hegui: (Looking away——) Why don't you go read the history books? Kageyama Tobio: She is very good at English and can speak many foreign languages. Kunimiying: She is very good at math and has a very smart mind. Oikawa Toru: She doesn't look like she has exercised at all, but her waist strength and other things are very strong. Hinata Shoyo: I can also play piano, bass guitar, and sing well. A certain Gojo Satoru who entered randomly: Actually, there are more! Crowd: How did you develop so many interests and hobbies? Huashanyuan Hegui: (smiling) I just learned it bit by bit. /// In short, this is a story about the heroine Mary Sue trying to make up for her regrets. *There is no cp in all directions in the full text. The heroine will not be with anyone. There are a lot of single arrows and gl-direction hints. Although I don't want to admit it, this is not a kind of female ticket. *The timeline is messy. In order to combine the two works, there have been a lot of changes, and the plot has been greatly changed. All for the sake of realizing my dream, I have written a fanfic, so just let me do it. *The full text is free and is not included in v. If it doesn't get messed up, I should be able to finish it (seriously). For details, please refer to the introduction to Chapter 1! Anyway, princesses, please come in! ! ! Mission: Good friends all over the world
