Global Reincarnation: Only I Know the Plot - Chapter 20:

Read at least six chapters, then prepare to crave the rest.The main character will show up in Chapter Five, though I don't recommend skipping the first four chapters.-----The world was celebrating. The Demon King was dead, along with his Darkness Generals.Humans led the other races to war for subjugation. They killed all, and none were spared. However, thousands of years before this happened, a piece of history was altered by time itself. In fact, the Demon King didn't have four generals but only one, which he sealed and sent into eternal slumber. Just as he started to close his eyes, the chains locked away for eternity shattered into pieces.

Yu Linglong is the shu (born of a concubine) daughter in a general’s family. Since her mother was only a tribute dancer, her position is the lowest of the low. She used to live with her mother outside the father’s residence, and they only received some monthly money from him. He didn’t bother seeing them. But when her mother dies, she moves into the general’s residence.

The general is a very irresponsible and violent man. He doesn’t really get attached to women, just letting his lust dictate his actions. His wife is a jealous woman, who killed one of his previous concubines, because he doted on her too much. She similarly wants to get rid of Yu Linglong, in part to vent her frustrations over her husband’s cheating habits.

Because the sixth miss – the general’s legitimate daughter, was bitten by a snake, she needs detoxification. The cure was apparently getting poisoned by scorpions, to fight one poison with another. But since she’s already weak, they decided it would be better if she drank the blood of someone poisoned by scorpions instead. The general’s madam naturally decided to use Yu Linglong’s blood. During the process of getting bitten by the scorpion, the original timid Yu Linglong died of fright (and maybe poison? it’s never made clear). Then Yu Mei takes over her body.

Yu Mei is a modern woman. She was some mafia boss, so she’s very capable with fighting and overbearing attitude. She died because the man she fell in love with betrayed her and killed her. So she doesn’t trust easily afterward.

Since she took over Yu Linglong’s body, she refuses to adapt to the circumstances of a lowly illegitimate daughter, and uses her violence to fight for a peaceful life, where no one will challenge her and plot against her. Basically, she beats them up into submission. In the meantime, she acquires a tail – a very persistent prince, who only seems to stick to her harder, the colder she treats him. Did ancient men have such heavy tastes, she wonders.

The Yan family and the Song family have a commercial marriage.
Song Nianying’s fiancée, Yan Chuyu, is known as a vampire on earth.
She has a feminine beauty, fair skin, bright red lips, and always has a seductive fragrance on her body. She has been educated by the heirs since she was a child.
But when two people try marriage together.
It was only then that Song Nianying realized that her wife was so cute.
She would actually blush because of a small approach of hers, and would often stare at her slender neck in a daze.
When she teased her again and again, Yan Chuyu would say coldly and arrogantly, “Don’t get too close.”
Song Nianying smiled and continued to approach, Yan Chuyu stared at her with eyes like ink: “This is the first time I have warned you.”
…
When she received the 320th warning, Song Nianying was ready to move, and decided to overturn the warning and take her down.
But that day.
Thunder and lightning flashed in the sky.
Yan Chuyu sat at the highest point of Xuanming Pagoda, her eyes were bright red.
Beside her, a maid with a pale face and blue eyes lowered her head and asked, “Wang, what is it about the house that makes you so afraid to go back?”
She has been with the king for so long, and she has never seen her so anxious and terrified. Could it be that she is a wolf clan?
Yan Chuyu raised his left hand and caught a bolt of lightning, forming an electric ball, and slowly replied: “My wife.”
