- Description from novelbuddy

Fang Ka, a man who became a necromancer in another world, made a shocking discovery: his consciousness was still linked to the internet networks of his previous life. By connecting online users’ minds to the undead he summoned, he turned what should have been a grim army into something far more dangerous—and unpredictable.

Since a young age, Su Qing already knew she was adopted and that her adopted parents didn’t like her. Hence, she learned to be independent as a child and became quite aloof. Aside from being slightly warmer toward her grandmother who she had lived with, she was indifferent to everyone else. Fearful that Su Qing’s mental health might be affected after her grandmother’s death, the doctors helped Su Qing find her biological parents and threatened them into taking Su Qing back.

However, once Su Qing returned to Su Manor, she was immediately cornered by her five older brothers, all warning her not to get too close to them! Su Qing, who held no expectations for the Su family, chose to ignore them. To everyone’s surprise, after a certain period of time, these five brothers seemed to have changed and kept hounding Su Qing.

Big Brother: This luxury mansion is for you. Do you like it? Second Brother: I heard you like sports cars. I just acquired this company, so just tell them what kind of sports car you like and they’ll make it for you. Third Brother: There’s a hundred million yuan in this card. Just ask me for more if this isn’t enough. Fourth Brother, carrying his laptop: I have scandals on everyone. You can see them all! Popular hunk Fifth Brother: I’ll scold whoever bullies you with my main social media account! When a man, who was kicked under the bed the first time they met, appeared at Su Manor’s door, asking Su Qing to proceed with their marriage as promised, all five brothers flew into a rage. “Scram! She’s our sister!” The man said, “Excuse me, she’s my wife.”
