DxD: I Steal Luck - Chapter 1: High School DxD?

Our MC dies from an accidental electrocution and ends up inhabiting the body of a young prince in another world, his new profession being the Necromancer he chose in the game he was playing before his untimely demise. However, things are not what they seem – including his own Necromancy skills!

Feng Lingxi was the traditional family’s head mistress – a person with a charismatic yet sly personality with the ability to attract people easily to her side, and having the potential to take someone’s soul away. Crossing across boundaries from a decade ago to now, a world that gives woman full respect and acknowledgement….

Don’t be fooled by her, because she was someone who would act obediently in front of a crowd but, stabs them in the back when necessary! Disguising as someone that would gain her trust and belief! That was why the Emperor of Xian started doting on her, allowing her to become absurdly daring to do whatever she liked. This made the Empress speechless to tears.
That would be the cause of the kingdom’s downfall in the near future…

Had to be a big badass in The Sims.

“Shen He, you don’t want Chongyun to be expelled from school, do you?”

“Captain Qin, you don’t want Barbara to be an idol, do you?”

“Gan Yu, you don’t want these photos to be seen by others, do you?”

“Lei Movie, you don’t want Guo Beng to be bullied at school, right?”

…………

In order to make up for the evil things done in the Sims, Li Xingshan can only accumulate virtue and do good in reality.

Who knew that one day, Shen He, holding a long spear, appeared in front of him: “Li Xingshan, if you have done all the bad things, I will kill you today and do justice for the heavens!”

Li Xingshan: ? ? Wait, aren’t those fake?
