I Attained Invincibility In The Real World - Chapter 12 - : Practice and Great Upgrade

When gods gather, lightning will strike and the earth will move. Immortals! Which of the numerous way to immortality should one follow? Immortals are hard to seek, but why should immortals hide? Heaven has no mercy, but humans have emotions, and these emotions hinder the road to longevity!

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 emaciated old man with an alien-like appearance grinned maliciously, while the young girl cried and howled.“Worm, worm, worm, worm, worm, worm...”Countless worms surged towards the girl like a tide, seemingly intent on devouring her completely.The girl instinctively closed her eyes and let out a desperate wail.“Someone... save me!”A breathtaking beam of light cut through the dimness, dispelling the girl's fear and the swarm of worms that filled her vision. Accompanied by a voice that was young but carried a hint of sunshine.“It's okay, I'm here. Big brother is here to protect you.”The boy with purple hair and purple eyes held a scythe in his hand, blocking in front of the girl, and issued a declaration of death to the old man.“You deserve to die, Zouken Matou. No, Makiri Zolgen!”
