Rebirth 70: I Relied on the System to Pamper Mr. Quan

[Travel through the ages, make a fortune, abuse scumbags and slap them in the face] Zhou Yunshu accidentally traveled to the 1970s and became a poor little boy who was forced by his stepmother to replace his step-sister in the countryside. In the beginning, she dragged her dying body to fight against the evil stepsister. Fortunately, the golden finger system was activated at the critical moment, allowing her to survive with the help of the system. Faced with verbal scoldings and beatings from her stepmother and vicious siblings, she appeared to be weak to win sympathy, but behind the scenes, she used the system to drain her family wealth, and then sent her in with a backhand. After going to the countryside, she found that she had actually dressed as cannon fodder in a period novel and died before even appearing. After being inexplicably targeted by the female protagonist many times and having the male protagonist make strange advances, Zhou Yunshu relied on the system to build a threshing machine to kill the female protagonist who framed her for surrendering. She used this to leave the countryside and become a member of the machinery factory. Then she relied on the system to modify tractors, develop new accessories, and polish firearms, gradually climbing to the pinnacle of scientific research. As a man who has made numerous meritorious deeds, Gu Rongchuan leads the best team. He originally wanted to protect the little girl he valued, but unexpectedly he was spoiled by her. The most advanced equipment, comprehensive protective gear, and incredible medicines, she used her own abilities to arm them to the teeth!
