When disaster strikes, all order collapses, money becomes meaningless paper, and discussions about order lose their significance. The only assurance that remains is power. And I, possessing power, can do as I please.In this post-apocalyptic world, besides growing stronger, Li Ming must also deal with the persistent neighbor who continually sends the wife to borrow food.“Ma'am, you can't always request food without offering anything in return, can you?”

Back in 1996, when the daughter of the Old Xie family, Xie Wanying, said she wanted to be a doctor, many laughed.“Phoenix begets phoenix, dog spawns dog. A truck driver’s daughter becoming a doctor is as likely as a sow climbing a tree.”“I’m not just going to be a doctor, I’m going to be a female chest surgeon,” said Xie Wanying.Her words provoked even greater waves of disdain within the doctors' community.Relatives who were doctors ridiculed her mercilessly: “Do you know how high the admission scores are for medical students? Do you think you can make it?”“There are zero female chief chest surgeons in the country. Who do you think you are!”A bunch of people mocked her: “You'll probably only get into a third-rate medical college and end up as a health worker in a small county town. It's easy to imagine what sort of marriage you'll have.”After the college entrance exams, Xie Wanying entered the top surgical class in the country with the highest science scores in the province, with department heads in the Capital’s top-tier hospitals vying for her from her internship beginnings.“Student Xie Wanying, come to our digestive surgery department.”“No, she must come to our urological surgery—”“Pediatric surgery is in short supply of female doctors like student Xie Wanying.”Circles of relatives and friends: …At this time, Xie Wanying independently completed the youngest Tetralogy of Fallot surgery in the country, represented the national association of chest surgery at an international medical forum, and published the world’s first minimally invasive heart valve repair surgery, becoming truly the foremost surgeon in the field of female surgery!As for the marriage concerns that everyone “worried” about:A brother from the Returned Overseas Faction, a hot bachelor within the Capital, changed his QQ profile picture to Junior Sister Xie.The young CEO, a handsome man, came to the hospital every day with flowers, keen to offer a diamond ring.Not to mention, a whole host of suitors had long since worn a path to the Old Xie Family's doorstep...

This is the story where Urahara Kisuke died after Nel failed to save him inside Askin’s Gift Ball Delux and reincarnated in the world of DxD.

I am not sure if I can capture Urahara’s character properly so I apologize in advance if you are not satisfied.

Also, English is not my native language.

I don’t own any of the characters from the canon.
