Guzhu, a retired professor-level senior engineer, was once a literary young man with a dream of being a writer. After his retirement, when he was writing time-travel novels on Tomato Novel Network, he woke up and actually traveled through time. He is in a remote mountain village by the Yangtze River in Sichuan, with a gurgling stream. The era here is similar to that of the Ming and Qing Dynasties but it belongs to an unknown parallel world.
He became an 8-year-old child with the same name, no golden finger, weak body, poor family, bad temper and constant quarrels. This "old kid" first went through a period of daze and adaptation, and then got acquainted with his relatives, friends and neighbors. He was determined to conceal his identity in time travel and uphold the principle of protecting himself wisely.
He secretly figured out the social structure and customs, and prioritized solving survival crises such as food and debt. Using professional knowledge, they secretly carried out ecological agriculture, used mountain streams to develop micro-hydropower, raised fish and pigs, found magnets, made copper wires, and built small motors and lathes.
Two years later, the mountainous area changed drastically because of him, which caused conflicts. He also discovered martial arts secrets, learned self-defense techniques at the age of 10, later visited famous teachers, and came down the mountain three years later. Unexpectedly, something happened to his family. After taking revenge, he made a fortune. At the same time, he cultivated his moral character and studied. He passed six yuan in the scientific examination and was favored for his poetry.
He made friends, made friends with heroes, gathered forces, made nails, bricks, glass, and developed solar and wind energy. Knowing that it is difficult to protect oneself without strength, he packaged modern ideas, united the peasant and working class, and relied on wisdom and strength to protect himself and others in this man-eating society.
