I'm Very Happy After Marrying the CEO Husband According to the Agreement - Chapter 79: Childhood plum is no match for Heaven.

Tang Long was brought to the Immortal Cultivation World by an immortal who noticed his affinity to wood and cultivation.
Relying on his amazing talent, became one of the five emperors of that world.
He failed his Heavenly Tribulation and had his soul scattered into pieces but one part found its way to Qin Haodong on Earth.
With his excellent medical skills, he became a divine doctor of traditional Chinese medicine and encountered the baby girl he made before going into the Cultivation World, whose mother was as pretty as a fairy. The little girl even asked him to find more lovers. What a cute girl…

She transmigrated into an orphan, thinking that she still had her boyfriend with her, yet in an instant, her world crashed. For the position of heir, he said, “Yao’er, why don’t you become my second wife?” A sentence destroyed her wishful thinking, causing her to end their relationship of two lives cruelly. Leaving the hustle bustle, she then lived in a forest, wanting to find an honest man to spend the rest of her life with. But not long after getting married, she realized that the honest man she married was a bit dishonest.

“If I don’t die… I swear I will act on all my evil thoughts..”

Not exactly everyone’s typical thought when they’re about to die. What will a cowardly young man do when reincarnated with the evil powers to redefine his destiny? Can the natural kindness of human nature triumph over evil? Will he become the cold-blooded demon king of legend, or will he forge his own path and rain down another kind of terror?

- Description from novelupdates

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.”
