Jiang Yu, a modern and quirky girl, accidentally slipped and fell into the sewer while shopping. When she opened her eyes again, she traveled to a remote and barren mountain village and became an orphan girl of the same name who was only fifteen years old, had low self-esteem and was neglected by her family. Memories of the original owner flooded into his mind. Jiang Yu looked at the adobe house with bare walls, the mean and indifferent tribesmen, and the days of not having enough to eat. He decided to change the timid temperament of the original owner. With modern thinking and clever brains, he opened up wasteland to get rich in this poor ravine, slapped the best in the face, and counterattacked in life. From a pitiful little person who could be bullied, he became a leader in getting rich respected by the whole village and even the town. Finally, he walked out of the mountains and lived his own splendid life.
