Modern Teyvat, bound to the Abyss Spiral

Teyvat calendar 2015, the fourth millennium after the end of the Demon War
Li Qingping, from Liyue, is 18 years old and a high school student. He has a deep spiral and a woman named Raiden Zhen in his mind.
The woman named Lei Dianzhen is beautiful and generous. She only eats Mora instead of rice. She always tells him that if he can't make it in Liyue, he can go to Inazuma to seek refuge with her sister and she will guarantee him wealth and glory.
But shouldn’t Thor have the final say over Inazuma?
And that Abyss Spiral is even more worrying. The first level of others are all Hilichurls, while his first level is elite Abyss Apostles, and it’s a fucking torrent.
He thought the situation would improve after passing the first level, but what awaited him was the Demon of Dust and the Demon of Tornado...
In order to support the spendthrift woman in his mind, he found a job at Yanshang Tea House.
The tsundere and proactive rich girl Keqing, the taciturn childhood sweetheart Shen He, the gentle and considerate transfer student Kamisato Ayaka...
Encountering these people, Li Qingping's work and life were not going smoothly.
