The Grindset Kid Lands in the Villain’s Childhood [Quick Transmigration]

In her previous life, Zhu Wuyu followed the grind culture to the letter, working herself to death at a young age. As it turns out, cultivation can't replace sleep. You can literally work yourself to death! After dying, he was bound to a System and sent into various power-fantasy novels, where he became a villainous child tasked with changing bad endings. Zhu Wuyu stretched his new body and decided to start grinding all over again. System: “You are forbidden from doing anything that goes against the original owner's personality.” The little workaholic, who had no intention of slacking off and was a rebellious, chuunibyou troublemaker with a bad temper who attacked everyone and wanted to destroy the world: “Oh T^T” [The legitimate son, spoiled and gloomy, whose mother died young In the original story, he bullied the male lead and became the last straw that broke the camel's back. After arriving, Juanjuan invited the male lead to team up and bully his scumbag dad.] [The young prince whose father died in battle and mother died young In the original story, he used his family's debt of gratitude as an excuse to target the male lead, his father's adopted son, at every turn. When the male lead returned to the capital carrying his father's coffin, Juanjuan rushed over to put him in his place, only to crash into him and land hard on his own backside. Juanjuan: “Mother, he hit me in the head with his knee!”] [The emperor's prematurely deceased young son, born to his beloved empress Juanjuan: “My big brother will be the Great Yonghe Emperor, and Juanjuan will be the Great Yonghe King!”] [The elder's son who bullied the power-fantasy male lead in the cultivation world Juanjuan went to humiliate the male lead, saying, “You're not worthy of becoming my father's disciple.” The male lead immediately knelt and said, “This disciple pays his respects to Master.” Juanjuan, who couldn't jump as high as the male lead's sword: ?] Reader's guide: 1. The protagonist is a troublemaking baby with an extremely unusual way of thinking. Not recommended for readers with high expectations for the protagonist's morals and values. 2. A little bit of everyone doting on the protagonist. The male leads and villains have platonic relationships, including but not limited to brotherly, friendly, and master-disciple bonds. 3. My own take on the everyday life of raising a child. I only like writing the characters as children, so the story will be nearly finished once they reach adulthood. The parents' romance is practically nonexistent. Theme: Work hard and strive to get everything.
