MTL - Charm King Poison Queen - Chapter 1008

He became a teacher at the best magic academy in the empire.
….For being mistaken for someone else.

Guo Miao, the national treasure of the Empire, committed suicide after completing a certain grand project. Everyone had theories about her motives, but no one was aware that she was a reincarnation and had simply ended her own life because there was nothing left for her to do. She did not expect to reincarnate back to her past life when she discovered that she was the Guo family’s real rich daughter. In her last life, she did not turn down her parents who came for her, only to find that her decision left her in the abyss.

Not only did her parents play favorites, but their fake rich daughter was also ruthless, framing her for a murder and isolating her, then leaving her to rot in jail while her stepfather died from depression. Now that she had reincarnated, she no longer sought familial warmth—only survival for the sake of those who truly loved her and to live her life! She earned countless honors and innumerable scientific discoveries by turning over a new leaf.

Everyone who used to belittle her now regretted life, bawling as they begged for her patents. She coldly watched as they humiliated themselves and snapped at them icily: Dream on! In this secular world, she was the goddess to all and the most coveted person of every rich kid in the Imperial Capital. A certain man: The proudest thing I’ve done in my life is winning her love!

When an era came to an end, various forces set foot in cultivation to compete for immortality. A young boy who spent most of the time sleeping got lucky in the troubled times and became an unparalleled immortal who could cover the sky with a snap of fingers. Was he going to live forever?

- Description from Novelupdates

Lin Feilu, or better known by her nickname—Green Tea Princess, was the best of all the scheming b*tches that the world had ever seen. She was the Oscar-winning actress among the masses with real life as her stage. Acting coy, slandering, feigning innocence, or playing the saint, she aced it all. Simply put, she was the proverbial villainess.

Ah, but retribution came way too early for this malicious personage and she died on her 27th birthday.

In death, Lin Feilu reflected on her career of 20 years as the Green Tea Princess. She was full of regret and remorse over the life she once led. She vowed, if there was an afterlife, she would atone for her misdeeds and be a good person.

She transmigrated into a five-year-old princess of the Dalin Dynasty. In the name of family, she had a sickly mother disfavoured by the emperor, a mentally challenged and daft older brother.

Her life was constantly in danger, with having little to eat and trying to stay warm.

The living environment was very harsh.

Lin Feilu, who wanted to be a good person: … You forced me! Sorry, I can only activate my unique skill.

Harem fight? Striving for favor? Climbing the ranks?

Apologies, but let me show you what it means to be slaughtered by a maxed out player.

Note: “Green Tea” is a woman who presents herself as innocent, sweet, and kind but is very scheming and calculative in reality.
